	== Upgrading notes for 1.42 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.35.

	Some specific notes for MediaWiki 1.42 upgrades are below:
	* MediaWiki 1.42 requires PHP 8.1 or above (up from 7.4) (T359868).
	* MediaWiki now requires Composer 2.x, and any related (vendor) files generated
	by Composer must be generated by Composer 2.x. Composer 1.x is mostly end of
	life by upstream, and using it will result in slower actions when downloading
	and installing packages. See the upstream blog post at
	https://blog.packagist.com/deprecating-composer-1-support/ for further
	information.

	For notes on 1.41.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.42 ===
	* Composer 1.x is no longer supported, and can no longer be used with MediaWiki.

	==== New configuration ====
	* $wgMicroStashType: This setting allows for control of the object cache backend
	for the MicroStash service.
	* $wgEditRecoveryExpiry: This setting sets the number of seconds for which to
	keep edit recovery data after each edit is stored.
	* $wgDjvuUseBoxedCommand and $wgDjvuShell: The first is a temporary flag to
	control whether or not to use BoxedCommand when wrapping DejaVu rendering, and
	the second sets the command to call if so.
	* $wgConditionalUserOptions: This setting makes it possible to define which user
	properties have defaults varying by user, without growing the user_properties
	table. The typical use-case is to enable a feature only for users created
	after a certain date when rolling out features on large wiki farms.
	* $wgGrantRiskGroups: This setting controls the risk levels for each grant, used
	to indicate on various UIs which grants should be considered risky. (T290790)
	* $wgTempAccountCreationThrottle: This setting is like AccountCreationThrottle,
	but to be used for managing temporary account creations.

	==== Changed configuration ====
	* $wgAutoCreateTempUser: This setting (in active development), which configures
	automatic 'temporary' user creation on page save, has had two changes:
	- it now supports multiple match patterns on the 'matchPattern' key; and
	- it now uses a different format for deciding how to label temporary accounts;
	if your wiki used temporary accounts before 1.42, you will need to override
	the configuration value to also match the old format of *$1.
	* $wgLogActionsHandlers: This setting, which configures handlers for different
	log actions, is now ObjectFactory compatible.
	* $wgBotPasswordsCluster and $wgBotPasswordsDatabase: These settings have been
	deprecated; use $wgVirtualDomainsMapping['virtual-botpasswords'] instead.
	* $wgMainPageIsDomainRoot: This setting is no longer considered experimental.

	==== Removed configuration ====
	* $wgDisableCookieCheck: Removed without deprecation.
	* $wgStatsCacheType: Removed without deprecation. Set $wgMicroStashType instead.
	* $wgJobSerialCommitThreshold: Removed without deprecation. Any setups using
	this config will perform just fine, but might be less performant.
	* $wgLogoHD: Deprecated since 1.35. Use $wgLogo instead.
	* $wgContentHandlerTextFallback: Deprecated since 1.37. No longer customizable.
	* $wgSquidPurgeUseHostHeader: Deprecated since 1.33. No longer customizable, and
	always true.
	* $wgAllowImageTag: Deprecated since 1.35. Instead, you can register an
	extension tag named <img>.
	* $wgMinimalPasswordLength and $wgMaximalPasswordLength: Deprecated since 1.26.
	Use $wgPasswordPolicy instead.
	* $wgUseMediaWikiUIEverywhere: Experimental, removed without deprecation.
	* $wgHTMLFormAllowTableFormat: Experimental, removed without deprecation.
	* $wgOpenSearchTemplate: Deprecated since 1.25. Instead, you can use
	$wgOpenSearchTemplates['application/x-suggestions+json'].
	* $wgUseSameSiteLegacyCookies: Removed without deprecation.

	=== New user-facing features in 1.42 ===
	* (T308160) filter: is now allowed in inline CSS in wikitext

	=== New developer features in 1.42 ===
	* (T326466) MediaWikiIntegrationTestCase's database and set-up code now avoids
	using dynamic properties, which was causing deprecation warnings in PHP 8.2.
	* (T13555) MediaWiki now includes styles that allow more accessible markup for
	section headings. MediaWiki's own HTML output will be changed in the future.
	More information: https://www.mediawiki.org/wiki/Heading_HTML_changes
	* (T193472) PHP Notice and Warning errors that are silenced (e.g. by the "@"
	operator, error_reporting directive, or Wikimedia\AtEase) are now logged to
	a new "silenced-error" channel.
	* (T347347) The CLI installer accepts a "--with-developmentsettings" argument
	to require the DevelopmentSettings.php file at install time.
	* (T350054) MediaWiki's ResourceLoader has been updated to add basic support
	for code-splitting (aka "tree-shaking") when using the Codex component
	library. A ResourceLoader module can now specify a list of "codexComponents"
	in its module defintion and ensure that only the code for those components
	gets sent to the client. More information:
	https://www.mediawiki.org/wiki/Codex#Subset_of_components
	* (T345185) The SessionProviderInterface now allows defining providers that
	are exempt from rights checks when auto creating users.

	=== Languages updated in 1.42 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.

	* (T356616) Added language support for Chinook Jargon (chn).
	* (T357879) Added language support for Ibibio (ibb).

	=== Breaking changes in 1.42 ===
	* (T340802) ResourceLoader: The targets system is no longer active; all modules
	will load on all platforms even if they are marked as desktop- or mobile-only
	in the 'targets' field, which is no longer read. As part of this, the internal
	methods RL\Module::setTarget() & ::getTargets(), and OutputPage::setTarget(),
	have been removed.
	* TitleArray, deprecated since 1.41, has been removed.
	* UserRightsProxy, deprecated since 1.38, has been removed.
	* SiteConfiguration::getConfig(), deprecated in 1.41, has been removed.
	* UserLoginCompleteHook is always called with its $direct parameter set to
	boolean true. The false case has been removed.
	* MagicWord::load() has been marked @internal, and may change in the future
	without further notice.
	* All classes that implemented the IDBAccessObject interface and all interfaces
	that extended it, no longer do that. See https://w.wiki/9DAX for more info.
	* The type of the last parameter of BeforeInitializeHook::onBeforeInitialize()
	and MediaWikiPerformActionHook::onMediaWikiPerformAction() changed from the
	MediaWiki class to the new ActionEntryPoint. Relevant methods are still
	available on the object.
	* Classes that override Maintenance::finalSetup() must now declare the $settings
	parameter and pass it on when calling the parent implementation.
	MaintenanceRunner will always provide this parameter when calling
	finalSetup().
	* WebResponse::disableForPostSend() is no longer static.
	* MediaWiki's virtualrest internal library has been removed, in favor of just
	using other HTTP libraries: Guzzle, MultiHttpClient or MwHttpRequest.
	* Several deprecated methods have been removed from the Content interface,
	in favor of the respective methods in ContentHandlers. Callers should
	use a more narrow interface like ContentRenderer or ContentTransformer
	when possible. The following methods have been removed from Content:
	- getParserOutput()
	- preSaveTransform()
	- preloadTransform()
	- prepareSave()
	* User::blockedFor() and AbstractBlock::getReason(), deprecated in 1.35, have
	been removed. Use AbstractBlock::getReasonComment() instead.
	* SerializedValueContainer::newUnified(), deprecated in 1.41 has been removed.
	* Use of ActorMigration for any of the following tables, deprecated since 1.34,
	is no longer supported:
	- archive
	- image
	- oldimage
	- filearchive
	- recentchanges
	- logging
	- ipblocks
	* ParserOutput::setFlag() and ::getFlag(), deprecated in 1.38, were removed. You
	should use ::setOutputFlag() and ::getOutputFlag() instead.
	* ParserOutput::getCategories(), deprecated in 1.40, has been removed. You
	should use ::getCategoryNames() and ::getCategorySortKey() instead.
	* ParserOutput::getTOCHTML(), deprecated in 1.40, has been removed. You should
	use ::getTOCData() instead.
	* The parser does not substitute the default category sort key at parse time;
	this is substituted when the category links table is updated instead. As a
	result {{DEFAULTSORT}} will affect all the contents of the page (not just
	categories added after the location of {{DEFAULTSORT}} in the article) and
	ParserOutput::getCategorySortKey() will return the empty string (still
	meaning "use the default sort key") instead of the immediate value of
	{{DEFAULTSORT}}. ParserOutput::getCategorySortKey() will directly reflect the
	category link contents, instead of having post-processing done to it
	(character references decoded, new lines replaced, language conversion). That
	post-processing is now done when the category links table is updated, and so
	it consistently applies even when categories are added directly via API.
	* PostgresUpdater::addPgEnumValue() unused everywhere, have been removed
	without deprecation. Use of ENUM is highly discouraged.
	* ILoadBalancer::getAnyOpenConnection() has been removed without deprecation,
	use ::getConnection() instead.
	* The unused method CommentStore::getFields() has been removed without
	depreaction.
	* LanguageConverter's internal properties, all deprecated in 1.35 or 1.36, have
	now had their deprecated property accessors dropped:
	- mConvRuleTitle
	- mUserVariant
	- mHeaderVariant
	- mMaxDepth
	- mVarSeparatorPattern
	- mLangObj
	- mTablesLoaded
	- mTables
	- mVariants
	- mMainLanguageCode
	- mVariantFallbacks
	- mFlags
	- mVariantNames
	- mDescCodeSep
	- mDescVarSep
	* OutputPage::addParserOutputText has been marked @internal since there are no
	known users of it. Its old behavior has been deprecated and will change
	in the future without further notice.
	* A some methods of ConnectionManager and SessionConsistentConnectionManager,
	previously deprecated, have been removed:
	- ::releaseConnection(), deprecated in 1.38; do not use
	- ::getWriteConnectionRef(), deprecated in 1.39; use getWriteConnection()
	- ::getReadConnectionRef(), deprecated in 1.38; use getReadConnection()
	- ::getLazyWriteConnectionRef(), deprecated in 1.39; use getWriteConnection()
	- ::getLazyReadConnectionRef(), deprecated in 1.38; use getReadConnection()
	* CoreParserFunctions::mwnamespace(), deprecated in 1.39, has been removed. Use
	CoreParserFunctions::namespace() instead.
	* Processor:: and ExtensionProcessor::getExtraAutoloaderPaths(), deprecated in
	1.39, have been removed; use ::getExtractedAutoloadInfo() instead.
	* MWExceptionHandler::rollbackMasterChangesAndLog(), deprecated in 1.37, has
	been removed. Use ::rollbackPrimaryChangesAndLog() instead.
	* Passing a custom database connection to DatabaseBlockStore::insertBlock(),
	deprecated since 1.41, is no longer supported.
	* LanguageConverterFactory::isTitleConversionDisabled(), deprecated in 1.36,
	has been removed. Use ::isLinkConversionDisabled() instead.
	* MediaWikiIntegrationTestCase::$tablesUsed has been deprecated. The framework
	now detects these automatically.
	* Passing an actor id to the constructor of UserIdentityValue, deprecated
	since 1.36, is no longer being supported.
	* Support for setting dynamic property on StatusValue object has been removed.
	To pass your arbitrary data along the object, use StatusValue::statusData
	property (which is always declared).
	* The global function wfReportTime(), deprecated since 1.40, has been removed.
	* The skin template parameter 'reporttime', deprecated since 1.41, has been
	removed.
	* WikiPage::getPageIsRedirectField(), deprecated since 1.41, has been removed.
	* WikiPage::insertRedirect(), deprecated since 1.41, has been removed.
	* Several methods in PageArchive, all deprecated in 1.38, have been removed:
	- ::listRevisions()
	- ::getRevisionRecordByTimestamp()
	- ::getArchivedRevisionRecord()
	- ::getPreviousRevisionRecord()
	- ::getLastRevisionId()
	- ::isDeleted()
	- ::getFileStatus()
	- ::getRevisionStatus()
	* Database, DatabaseInstaller, DatabaseUpdater, DBPrimaryPos, ResultWrapper and
	SQLPlatform are no longer stable to extend. It is not possible to define
	database types in an extension.
	* UserDef::PARAM_ALLOWED_USER_TYPES now differentiates between temporary account
	usernames and user accounts. Any endpoints that want temp users to be
	valid but were passing a name through will break. Temp users must now be
	explicitly allowed.
	* The Hooks class, a legacy wrapper for HooksContainer, has been removed. All of
	its contents have been previously deprecated in 1.35 (or 1.41 for ::runner()):
	- ::register()
	- ::clear(),
	- ::isRegistered()
	- ::getHandlers()
	- ::run()
	- ::runWithoutAbort()
	- ::runner()
	* Article::__get(), ::__set(), deprecated since 1.35, have been removed.
	* Several API calls have been updated to return a 'temp' user flag:
	- ApiQueryImageInfo
	- ApiQueryLogEvents
	- ApiQueryRecentChanges
	- APIs extended from ApiQueryRevisionsBase
	* Parser::getCustomDefaultSort() and ::setDefaultSort(), deprecated since 1.38,
	have been removed.
	* UserOptionsLookup::getDefaultOptions() and ::getDefaultOption() now accept a
	UserIdentity, to take conditional defaults for user properties into account.
	When run on a wiki where conditional defaults are used, calling those methods
	without the UserIdentity might produce unexpected results.
	* Installer-related classes have been namespaced without having aliases added.
	The following have been moved to MediaWiki\Installer:
	- CliInstaller
	- DatabaseInstaller
	- InstallDocFormatter
	- Installer
	- InstallerOverrides
	- InstallerSessionProvider
	- LocalSettingsGenerator
	- MysqlInstaller

	been removed.

	use `mediawiki.cookie` instead
	* The no-op module `es6-polyfills` (deprecated as of 1.41) has been removed.
	* Log formatters (as defined in $wgLogActionsHandlers) are now created by
	ObjectFactory, which means their constructors must be public. Legacy log
	formatters using callbacks instead of class names are no longer supported.
	* The old aliases for the namespaced ResourceLoader classes, deprecated since
	they were moved in MediaWiki 1.39, have now been dropped:

	* BlockListPager::getTotalAutoblocks() was removed.

	=== Deprecations in 1.42 ===
	* (T273239) wfGetDB(), deprecated in 1.39, now emits deprecation warnings. Most
	code can migrate to MediaWikiServices::getInstance()->getConnectionProvider()
	->getReplicaDatabase() or …->getPrimaryDatabase() as appropriate.
	* (T166010) All PHP code in MediaWiki is slowly being moved to be in a class
	namespace as appropriate, so that we can use PSR-4 auto-loading, which will
	speed up general code loading of MediaWiki. The old global namespace class
	names are being left behind as deprecated aliases.

	deprecated. Provide the error message when constructing the Exception,
	or if you need a whole custom error page, use ErrorPageError instead.

	the $context parameter is now deprecated.
	* Using `WikiImporterFactory::getWikiImporter()` without the $performer

	instead, or simply `vendor/bin/phpunit`, which use bootstrap.php and

	for `$wgCommandLineMode` can be replaced with `MW_ENTRY_POINT === 'cli'`.

	the StatusFormatterFactory.
	* Html::buttonAttributes() and Html::getTextInputAttributes() methods
	no longer do anything and have been deprecated.
	* DatabaseBlock::doAutoblock and ::updateTimestamp are now deprecated, use
	DatabaseBlockStore::doAutoblock and ::updateTimestamp instead.
	* The MediaWiki class has been deprecated. Type hints in hooks should be
	changed to refer to MediaWikiEntryPoint instead. Note that extensions should
	not define their own entry points and should not interfere with the state of
	MediaWikiEntryPoint instances.
	* Various methods in ObjectCache have been deprecated and their equivalent made
	available in ObjectCacheFactory, use them instead:
	- ::getInstance() -> ObjectCacheFactory::getInstance()
	- ::newFromParams() -> ObjectCacheFactory::newFromParams()
	- ::newAnything() -> ObjectCacheFactory::newInstance(
	ObjectCache::getAnythingId() )
	- ::getLocalServerInstance() -> ObjectCacheFactory::getLocalServerInstance()
	- ::clear() -> ObjectCacheFactory::clear()
	- In addition, the ObjectCache::$instances member has been deprecated as well.

	RevisionRecord or WikiRevision; passing an integer revision id has been
	deprecated and emits a warning.

	and emits a warning; pass an empty string or use `::unsetPageProperty()`
	instead.
	* Passing a non-string value to ParserOutput::setPageProperty() has been
	deprecated; use ::setNumericPageProperty() instead.
	* Passing a non-scalar value to ParserOutput::setPageProperty() will emit
	a warning (it has never worked).
	* ParserOutput::setLanguageLinks() has been deprecated.
	* ParserOutput::getTimestamp() and ::setTimestamp() have been deprecated; use
	::getRevisionTimestamp() and ::setRevisionTimestamp() instead.

	matches the name of the corresponding getter, ParserOutput::getRawText().
	* ParserOutput::addTemplate() will emit a deprecation warning if it is called
	with a non-local title, such as an interwiki link. In a future release it will
	throw InvalidArgumentException.

	- Parser::$mHighestExpansionDepth, deprecated since 1.35
	* ApiQueryBlockInfoTrait::addBlockInfoToQuery() will emit deprecation warnings
	and will soon stop working due to schema changes. Instead use

	ApiUpload::getUploadImageInfo() instead.
	* DatabaseBlockStore::updateTimestamp() is now internal and should not be
	called.

	use MainConfigDependency instead.

	WebRequest::getCookie().

	== MediaWiki 1.41.0-rc.0 ==

	== Upgrading notes for 1.41 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.35.

	Some specific notes for MediaWiki 1.41 upgrades are below:
	* (T178356) MediaWiki now requires browsers to support ES6 for them to receive
	JavaScript, up from ES5. In practice, this primarily means that users of
	Internet Explorer 11 (EOL in 2022) will no longer get JavaScript tools.

	For notes on 1.40.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.41 ===
	* $wgGroupPermissions: The 'purge' permission is now considered an
	implicit right that can be rate limited, but not revoked. This has
	effectively already been the case for a long time, see T291316.

	==== New configuration ====
	* $wgPrivilegedGroups – Users belonging in some of the listed groups will be
	audited more aggressively.
	* $wgPageLinksSchemaMigrationStage – This temporary flag lets you control the
	migration stage for converting the pagelinks database table into normal form.
	* $wgExternalLinksDomainGaps – Can be used by large wikis to optimize certain
	external link queries.
	* $wgResourceLoaderEnableSourceMapLinks - Add a SourceMap header to
	ResourceLoader responses for JavaScript modules (T47514).
	* $wgVirtualDomainsMapping - Mapping of virtual domains to other dbs. It's
	useful to get connection to the external cluster.

	==== Changed configuration ====
	* $wgAuthManagerAutoConfig – When using this setting to modify the
	authentication system in MediaWiki, the classes
	TemporaryPasswordPrimaryAuthenticationProvider,
	LocalPasswordPrimaryAuthenticationProvider and
	EmailNotificationSecondaryAuthenticationProvider now require
	DBLoadBalancerFactory, not DBLoadBalancer, as a service.
	* $wgUseFileCache is no longer used for ResourceLoader module caching.
	* $wgLBFactoryConf['secret'] has been replaced by $wgChronologyProtectorSecret.

	==== Removed configuration ====
	* $wgCommentTempTableSchemaMigrationStage – This temporary flag did let you
	control the migration stage for the temporary comment database table, from
	revision.
	* $wgExternalLinksSchemaMigrationStage – This temporary flag did let you
	control the migration stage for the externallinks database table.
	* $wgParserOutputHooks - This array interacted with
	ParserOutput::addOutputHook(), which has been deprecated since 1.38 and was
	removed in this release.

	=== New user-facing features in 1.41 ===
	* Special:RandomPage can now take multiple namespaces in its URL, split by ','.
	* The aria-level HTML attribute is now allowed in wikitext by the Sanitizer.

	=== New features for sysadmins in 1.41 ===
	* $wgDBssl can now enabled in the installer when the database type is
	Postgres or MariaDB/MySQL (T335828).
	* MWHttpRequest will forward 'tracestate' and/or 'traceparent' headers when
	those are present in the original request and $wgAllowExternalReqID is set
	to true.
	* MultiHttpClient will send X-Request-Id header and additionally will forward
	'tracestate' and/or 'traceparent' headers when those are present in the
	original request and $wgAllowExternalReqID is set to true.

	=== New developer features in 1.41 ===
	* Added ForeignResourcesDir extension.json / skin.json attribute, which should
	point to the directory holding your foreign-resources.yaml file. See
	https://www.mediawiki.org/wiki/Foreign_resources for background.
	* Added PrivilegedGroups attribute for extension.json / skin.json, which lets
	you add any new user groups you define to wgPrivilegedGroups (see above).
	* Added a .gitmessage commit template. To use it, run:
	`git config commit.template .gitmessage`
	* A new hook, TextSlotDiffRendererTablePrefixHook, has been added to allow
	extensions to add content within #mw-content-text but after the
	DifferenceEngineViewHeader or DifferenceEngineShowDiffPage hooks have been
	run. The new hook is used to add elements within a horizontal display area,
	where their order can be explicitly set. Examples of uses for this include
	adding the VisualEditor diff-type switch, and the legend for inline diffs that
	is displayed if Wikidiff2 is installed.
	* validation callbacks for HTMLForm fields can now return Status objects.
	HTMLForm::validate will convert good Status instances to true and Status
	instances to a string containing a list with the errors.
	* ?action=rollback, if successful, will fire core's postEdit JavaScript hook;
	for now, we do not display a success message to the user via mw.notify(),
	as the RollbackAction form's success page is already shown
	* MultiHttpClient constructor will accept `headers` property which defines a
	set of headers attached to every request performed by the client.
	* New `Wikimedia/Http/TelemetryHeadersInterface` interface that provides a
	telemetry information which could be attached to HTTP Requests
	* Wikimedia/Http/TelemetryHeadersInterface can be passed to MultiHttpClient
	via 'telemetry' option.

	Extensions providing support for wiki-farm can use this to provide a global
	registration date (across all wikis), for example.
	* When $wgUseXssLanguage is set to true (enabled by default in
	DevelopmentSettings.php), ?uselang=x-xss can be used to easily test
	whether all messages are being escaped correctly.
	* Html::noticeBox accepts new optional parameters, 'heading' & 'iconClassName'.
	'heading' allows to pass an string as title; 'iconClassName' overwrites the
	default info icon.

	== MediaWiki 1.40.0-rc.0 ==

	== Upgrading notes for 1.40 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.35.

	Some specific notes for MediaWiki 1.40 upgrades are below:
	* Maintenance scripts should now be executed using maintenance/run.php, e.g.
	maintenance/run.php update not maintenance/update.php as before.
	* Five extensions have now been bundled with MediaWiki:
	* The DiscussionTools extension, which provides a forum-like editing
	experience for wikitext-based discussion pages.
	* The Echo extension, which provides a system of user notifications.
	* The Linter extension, which warns about use of deprecated wikitext.
	* The LoginNotify extension, which warns users about failed attempted logins.
	* The Thanks extension, which lets users thank editors for edits.
	* The Renameuser extension has been moved to MediaWiki core. It is now possible
	to rename users without installing an extension. The extension had already
	been bundled with MediaWiki since 1.18.

	For notes on 1.39.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.40 ===
	* When computing PBKDF2 password hashes, MediaWiki now detects and uses OpenSSL
	support if available, unless $wgPasswordConfig['pbkdf2']['class'] is set in
	LocalSettings.php. OpenSSL is more efficient, so if that setting is present,
	you should remove it (or set it to 'Pbkdf2PasswordUsingOpenSSL' if possible).
	If users get an internal error when trying to log in, you can try setting it
	to 'Pbkdf2PasswordUsingHashExtension'. In particular, this would be necessary
	if existing PBKDF2 password hashes were computed using a hash algorithm other
	than "sha512" or "sha256" (the current and prior defaults).
	* You should configure your webserver to return the http header
	'X-Content-Type-Options: nosniff' for the /images directory. This will
	instruct browsers to not apply content sniffing when accessing the files.
	MediaWiki before 1.40 shipped with a content sniffer which disallowed
	potentially dangerous files at upload time, but this protection has now been
	removed in favor of this 'X-Content-Type-Options: nosniff' header and the
	installer will return a warning when it is not in place.
	* Support for MW_USE_LEGACY_DEFAULT_SETTINGS has been removed, setting this
	constant will not have any effect. Use of MW_USE_LEGACY_DEFAULT_SETTINGS
	had been deprecated since 1.39.

	==== New configuration ====
	* $wgThumbnailNamespaces - This setting lets you define the namespaces for which
	image thumbnails (or a placeholder in the absence of a thumbnail) will be
	displayed on Special:Search.
	* $wgResourceLoaderClientPreferences – This experimental flag lets you enable
	client-side preferences for logged-out users.
	* $wgExternalLinksSchemaMigrationStage – This temporary flag lets you control
	the migration stage for the new schema for the external links database table.
	Ignore it unless you have a large wiki farm with complex migration needs.
	* $wgCommentTempTableSchemaMigrationStage – This temporary flag lets you control
	the migration stage for the temporary comment database table, from revision.
	Ignore it unless you have a large wiki farm with complex migration needs.
	* $wgSpecialContributeSkinsEnabled – This setting lets you list skins on which
	Special:Contribute is available, for where others don't work for the feature.
	* $wgPrivilegedGroups – Users belonging in some of the listed groups will be
	audited more aggressively.

	==== Changed configuration ====
	* $wgPasswordPolicies – This setting, which controls what makes for a valid
	password for wiki accounts, has been adjusted to raise the minimal password
	length from 1 to 8 characters. The initial limit of 1 has been in place since
	MediaWiki 1.26. If you wish to allow shorter passwords, you can over-ride it
	in your LocalSettings following the guidance on MediaWiki.org.
	* (T254045) New accounts can no longer use an equals sign (=) in their
	usernames because of issues it causes in wikitext syntax. This can be
	adjusted by changing the value of $wgInvalidUsernameCharacters.
	* (T314318) $wgParserEnableLegacyMediaDOM – This setting has been changed, so
	the alternative modern HTML structure for media is now the default. You can
	disable it for now by over-riding this back to `true` in LocalSettings, but
	this configuration will be removed in future versions of MediaWiki. For more
	details, see the documentation at:
	https://www.mediawiki.org/wiki/Parsoid/Parser_Unification/Media_structure/FAQ
	* $wgWatchlistExpiryMaxDuration – This setting, which controls the maximum
	allowed duration for users to set their temporary watchlist entries for expiry
	if that feature is enabled, has been increased from 6 months to 1 year.

	==== Removed configuration ====
	* $wgShellboxUrl – This setting, deprecated in 1.37, has now been removed; use
	$wgShellboxUrls instead.
	* $wgMainWANCache and $wgWANObjectCaches – These never-used settings have been
	removed. To inject WANObjectCache parameters, use $wgWANObjectCache instead.
	These variables were introduced for multi-DC wiki farms to add a separate
	memcached proxy for cross-DC relaying of purges but never used because
	WANObjectCache works based on route prefixes, which can be transparently
	handled by the main memcached proxy.
	* $wgParserTestFiles – This setting, deprecated in 1.30, has now been removed;
	extensions can place their parser test files in `tests/parser` instead.
	* (T231412) $wgAutoloadAttemptLowercase – This setting, deprecated in 1.35, no
	longer has any effect. If you run into difficulties, fix the names of miscased
	local files.
	* (T309787) $wgVerifyMimeTypeIE – This setting, to provide extra security checks
	for very old versions of Internet Explorer clients, was removed. These user
	agents aren't used in practice, and haven't been served JavaScript content for
	years.

	=== New user-facing features in 1.40 ===
	* Special:Search can now show thumbnails for results for titles outside NS_FILE.
	This is controlled via the new onSearchResultProvideThumbnail hook.
	* A new preference ('search-thumbnail-extra-namespaces') to allow users to
	control whether to show more thumbnails (per $wgThumbnailNamespaces)
	* (T324910) On pages using multi-content revisions, the raw content of a
	specific slot can be retrieved using the action=raw&slot=<role-name> query
	parameters.
	* (T313804) The preferences page now provides a search bar to find preferences,
	regardless of the tab on which they appear.

	=== New developer features in 1.40 ===
	* The MediaWiki-Docker development environment is now configured to
	run on PHP 8.1 by default, up from PHP 7.4 now that that's EOL.
	* Vue development mode is enabled by default in DevelopmentSettings.php
	* (T277618) The @noVarDump annotation from the DebugInfoTrait tool can now be
	added to references to stop them from being expanded when their object is
	passed to var_dump(), to make its use for debugging more feasible.
	* The ApiSandbox will now by default request responses in the latest API format,
	rather than the original format. Users can set `formatversion` to a different
	value if needed.
	* A new hook, GetBlockErrorMessageKeyHook, allows extensions' block error
	messages to be received and displayed by BlockErrorFormatter.
	* A new hook, SpecialCreateAccountBenefits, lets extensions and local code set
	custom content on the signup page about the benefits of using an account.
	* (T321412) A new 'PageUndeleteComplete' hook has been added for more thorough
	information about a page post restoration than the 'PageUndelete' hook passes.
	This provides similar functionality to the 'PageDeleteComplete' hook.
	* The Linker::specialLink() method can now link to a Special page's with a sub-
	page or action parameter set, e.g. [[Special:Contributions/JohnDoe]].
	* The PHPUnit entrypoints (tests/phpunit/phpunit.php and vendor/bin/phpunit)
	now check if composer dependencies are up-to-date, like update.php, using
	CheckComposerLockUpToDate. To disable this check, use
	MW_SKIP_EXTERNAL_DEPENDENCIES=1 environment flag when running PHPUnit.
	* ManualLogEntry::setForceBotFlag() has been added to allow the forcing of the
	bot flag for log entries which are inserted to the recent changes.

	=== Other changes in 1.40 ===
	* Calling RecentChange::doMarkPatrolled() with $auto = true has no effect and
	logs a warning. Since 1.31, it would mark the change as manually patrolled,
	but would not log it as such in patrol log and would still require
	'autopatrol' right (not 'patrol'). Generally, whether a change should become
	autopatrolled, is usually determined before it's inserted in the database.
	* In versions of MediaWiki before 1.39, the table of contents location
	was marked internally with <mw:toc>...</mw:toc>; in version 1.39
	this was changed to an empty tag <mw:tocplace />. In 1.40 this has
	been changed a final time to use an empty <meta> tag for future
	Parsoid compatibility (see Parser::TOC_PLACEHOLDER). This may
	affect you if stale content is left in the ParserCache or if your
	skin did manual ToC replacement without using the recommended
	Parser::replaceTableOfContentsMarker() function.
	* Skins can now choose which Codex theme should be loaded by setting the
	SkinCodexThemes attribute in their skin.json file.
	* The parser test framework has been updated, and the 'pst', 'ill', 'cat'
	and 'showflags' options have slight differences in their output. These
	options are not much used outside core, but third parties may need to
	update parser tests.
	* (T332889, CVE-2023-36675) SECURITY: Fix escaping in BlockLogFormatter.

	== Compatibility ==

	MediaWiki 1.40 requires PHP 7.4.3 or later and the following PHP extensions:

	* ctype
	* dom
	* fileinfo
	* iconv
	* intl
	* json
	* mbstring
	* xml

	MariaDB is the recommended database software. MySQL, PostgreSQL, or SQLite can
	be used instead, but support for them is somewhat less mature.

	The supported versions are:

	* MariaDB 10.3 or higher
	* MySQL 5.7.0 or higher
	* PostgreSQL 10 or later
	* SQLite 3.8.0 or later

	== MediaWiki 1.39.0-rc.0 ==

	== Upgrading notes for 1.39 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.31.

	Some specific notes for MediaWiki 1.39 upgrades are below:
	* (T278139) Drop PHP 7.3 support in MediaWiki 1.39; require 7.4.3 or higher.

	For notes on 1.38.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.39 ===

	==== New configuration ====
	* $wgAutoCreateTempUser – This configures automatic user creation on page save.
	* $wgCopyUploadAllowOnWikiDomainConfig – This configures if administrators can
	use the MediaWiki:Copyupload-allowed-domains system message to define which
	domains can be used with the upload-by-url tool.
	* $wgCdnMatchParameterOrder – This can be set to false if MediaWiki is behind a
	CDN that re-orders query parameters. This will make the code that matches
	request URLs to canonical CDN URLs insensitive to parameter order.
	* $wgMultiShardSiteStats – This allows you to split site_stats across multiple
	rows. Only useful for very large, heavily edited wikis. (T306589)
	* $wgPrivilegedGroups – Users belonging in some of the listed groups will be
	audited more aggressively.

	==== Changed configuration ====
	* $wgInvalidUsernameCharacters – This setting now contains the char '>', which
	is now the reserved delimiter for external user names.
	* $wgLocalFileRepo – The default serialization method for file meta-data has
	been changed to JSON. You can revert it to PHP by setting the property
	'useJsonMetadata' to false.
	* $wgLBFactoryConf – The 'configCallback' flag can now be set to a callback
	function that returns an array with keys to update in $wgLBFactoryConf. This
	can be used to update the database configuration on the fly, e.g. to take
	replica hosts out of rotation.
	* $wgDBservers and $wgLBFactoryConf – The DBO_SSL flag in has been deprecated in
	favour of a boolean "ssl" parameter.
	* $wgObjectCaches – The 'globalKeyLB' and 'localKeyLB' flags are no longer
	supported.

	==== Removed configuration ====
	* $wgMultiContentRevisionSchemaMigrationStage - This transition flag, deprecated
	since MediaWiki 1.35, has been removed; the data migration is over.
	* $wgActorTableSchemaMigrationStage - This transition flag has been removed; the
	data migration is over.
	* $wgWikiFarmSiteDetector – This experimental setting has been removed without
	replacement. Use the MW_WIKI_NAME environment variable to specifiy the name of
	the site for which to load configuration. Using the WIKI_NAME environment
	variable for this purpose is deprecated.
	* $wgParserCacheUseJson - The ParserCache now always uses JSON serialization.
	Reading old non-JSON cache entries is still supported. The setting had been
	deprecated since 1.36.
	* $wgAllowJavaUploads - To allow uploads of JAR files, remove application/java
	from $wgMimeTypeExclusions.
	* $wgMaxRedirects – This broken feature was removed, as it never worked as
	intended (T296430).
	* $wgElementTiming – This experimental, default-disabled feature has been
	removed without replacement.
	* $wgPriorityHints and $wgPriorityHintsRatio – The related experimental feature
	has been removed without replacement.
	* $wgIncludeLegacyJavaScript – This flag has been removed, without loss of any
	functionality in this release. Most former "wikibits" functions were removed
	after deprecation in previous releases. The remaining functions, such as
	importScript, are now available unconditionally.
	* $wgLegacySchemaConversion - This unused setting has been removed.
	* $wgInterwikiPrefixDisplayTypes - This unused setting has been removed.
	* $wgMangleFlashPolicy – This is no longer functional, and is now deprecated.
	Users who are somehow still using Flash as a browser extension will be exposed
	to CSRF vulnerabilities.

	=== New user-facing features in 1.39 ===
	* Optional automatic user creation on page save ($wgAutoCreateTempUser)
	* Administrators now have the option to delete/undelete the associated "Talk"
	page when they are (un)deleting a given page. `deletetalk` and `undeletetalk`
	options were added to the 'delete' and 'undelete' action APIs in MW 1.38.
	* `{{=}}` is now a wikitext built-in magic word, expanding to `=`. This is
	conventionally used as an escape mechanism to allow the use of `=` in
	unnamed template arguments. Defining [[Template:=]] to expand to something
	other than `=` has been deprecated since 1.36, with affected pages put into
	a special tracking category for migration.
	* (T284020) Bot passwords are now supported when using the REST API.

	=== New developer features in 1.39 ===

	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* Actual localization was added for several languages, which were already
	in Names.php and even used for a Wikipedia:
	** (T313200) Added language support for Rundi (Kirundi, rn).
	** (T310976) Added language support for Tumbuka (ChiTumbuka, tum).
	** (T314270) Added language support for Kanuri (kr).

	and the "File" namespace is now "Faili". The old name of the "File" namespace
	was "Picha", and it's kept for backwards compatibility. If you manage a wiki
	in Swahili, and you use "Faili:" as a namespace anywhere in wikitext, and
	you mean to use it as "Media:", these need to be replaced to "Media:".
	* (T309866) Some namespace translations were updated for Kyrgyz (ky). The old
	ones are retained as aliases for backwards compatibility.
	* (T117845) Started the renaming of the language codes for Serbian from sr-ec
	and sr-el to sr-cyrl and sr-latn.

	migrations in extension tables.

	=== Other changes in 1.39 ===
	* Dynamic default values are now applied before extension registration callbacks
	are run. This way, extensions have a complete view of config variables, with
	all defaults applied. For example, when the default value of X used to be
	static but becomes dynamic, and an extension reads the value of X in the
	registration callback, it will now continue to function as expected. In some
	cases however, this may cause an undesired change in behavior: if the dynamic
	default of setting X depends on the value of setting Y, and an extension
	changes Y, the changed value of Y will no longer affect the value of X.

	== Compatibility ==

	MediaWiki 1.39 requires PHP 7.4.3 or later and the following PHP extensions:

	* ctype
	* dom
	* fileinfo
	* iconv
	* intl
	* json
	* mbstring
	* xml

	MariaDB is the recommended database software. MySQL, PostgreSQL, or SQLite can
	be used instead, but support for them is somewhat less mature.

	The supported versions are:

	* MariaDB 10.3 or higher
	* MySQL 5.7.0 or higher
	* PostgreSQL 10 or later
	* SQLite 3.8.0 or later

	== Online documentation ==
	Documentation for both end-users and site administrators is available on
	MediaWiki.org, and is covered under the GNU Free Documentation License (except
	for pages that explicitly state that their contents are in the public domain):

	https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation

	== Mailing list ==
	A mailing list is available for MediaWiki user support and discussion:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

	A low-traffic announcements-only list is also available:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

	It's highly recommended that you sign up for one of these lists if you're
	going to run a public MediaWiki, so you can be notified of security fixes.

	== Upgrading notes for 1.38 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.29.

	Some specific notes for MediaWiki 1.38 upgrades are below:
	* (T191740) The AbuseFilter extension is now bundled with MediaWiki. This is an
	anti-abuse feature that lets privileged users to set specific actions to be
	taken when actions by users, such as edits or file uploads, match certain
	criteria.
	* (T232948) The Math extension is now bundled with MediaWiki. This is a content
	feature that lets users create mathematical formulæ, written in a sub-set of
	LaTeX and rendered in MathML with a fallback SVG image. By default, it will
	use Wikimedia's mathoid service to render each formula, but local rendering
	can be set up for network isolation or performance.
	* (T191743) The Minerva skin is now bundled with MediaWiki. This is a simple,
	light-weight, and scalable skin that is particularly optimised for mobile use,
	and integrates well with the MobileFrontend extension (available separately),
	but can also be used as a regular desktop skin.

	For notes on 1.37.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.38 ===

	==== New configuration ====
	* (T297708) $wgMaxExecutionTimeForExpensiveQueries - This setting can be used to
	control the maximum execution time for several expensive query pages (e.g.
	RecentChanges and UserContribs).
	* $wgBrowserFormatDetection – This setting allows overriding browsers' automatic
	detection and handling of formats. It's initially used to prevent auto-linking
	of possible telephone numbers in wiki pages' output in Safari on iOS; this can
	be re-enabled if you wish, or locally extended for other browsers' quirks.
	* (T240685) $wgMetricsTarget, $wgMetricsFormat, $wgMetricsPrefix - These provide
	configuration for a new MetricsFactory service with support for the dogstatsd
	format, intended for integration with Prometheus integration.
	* $wgGroupInheritsPermissions – This setting allows inheriting permissions, both
	granted and revoked, from another group.
	* $wgForeignApiRepos – ForeignAPIRepo now has a apiMetadataExpiry option to
	control for how long file metadata is cached. Additionally the default changed
	from 1 hour to 4 hours.
	* $wgSkinsPreferred – This lets you set a list of preferred skins to be listed
	higher in Special:Preferences.
	* $wgWikiFarmSettingsDirectory – A directory that contains site-specific
	configuration files. Setting this will enable multi-tenant ("wiki farm")
	mode, causing site-specific settings to be loaded based on information from
	the web request. EXPERIMENTAL.
	* $wgWikiFarmSettingsExtension – The file extension to be used when looking up
	site-specific settings files in $wgWikiFarmSettingsDirectory, such as 'json'
	or 'yaml'. EXPERIMENTAL.
	* $wgWikiFarmSiteDetector – A callback function that returns the name of the
	wiki for the current request. This is used in multi-tenant ("wiki farm")
	mode to determine which settings file to load from
	$wgWikiFarmSettingsDirectory. EXPERIMENTAL.
	* $wgEnableRemoteBagOStuffTests – This replaces the environment variable
	PHPUNIT_USE_BAGOSTUFF.
	* (T230211) $wgForceDeferredUpdatesPreSend – Force deferred updates to be run
	before sending a response to the client, instead of attempting to run them
	after sending the response. Setting this to true is useful for end-to-end
	testing, to ensure that the effects of a request are visible to any subsequent
	requests, even if they are made immediately after the first one. Note however
	that this does not ensure that database replication is complete, nor does it
	execute any jobs enqueued for later.
	* $wgTemplateLinksSchemaMigrationStage – Templatelinks table schema migration
	stage, for normalizing tl_namespace and tl_title fields.

	==== Changed configuration ====
	* $wgStyleDirectory and $wgExtensionDirectory – These are now set later, so can
	no longer be used within LocalSettings.php unless explicitly set in that file.
	* $wgFileBackends – This setting no longer takes 'fileJournal' as an option.
	* $wgMaxImageArea - This setting may now be set to false to disable size.
	checking before scaling. Extensions can still override its value by using the
	BitmapHandlerCheckImageArea hook.
	* $wgAjaxUploadDestCheck – This is now deprecated, and act as always-true.
	* $wgInterwikiCache – This no longer supports the string value for CDB files.
	* $wgParserOutputHooks – This is now deprecated; adjustments using this should
	be done with OutputPageParserOutputHook instead. (T292321)
	* $wgExternalStores – This is newly documentated in
	includes/externalstore/README.md.

	==== Removed configuration ====
	* $wgShellLocale - This setting has been removed as it was a flawed solution to
	the problem of locale dependence, MediaWiki will now always set a locale of
	C.UTF-8 or C and works around the remaining problems of the C locale by not
	using escapeshellarg. This follows the direction of PHP 8.0, which sets a
	locale of C by default instead of respecting LC_CTYPE.
	* $wgLoggedOutMaxAge - Experiment removed, originally added in 1.35. (T293848)
	* $wgIncludejQueryMigrate - Deprecated in 1.36. We only support jQuery v3.
	* $wgUseCategoryBrowser - This experimental feature has been removed. If you
	still need to use this feature, please see [[mw:Extension:CategoryExplorer]].
	* $wgStyleSheetPath - alias for $wgStylePath, deprecated since 1.3 (2004).

	=== User-facing changes in 1.38 ===
	* (T284921) The "auto-number headings" feature was removed following a
	consultation, due to performance reasons.

	=== New operator/developer features in 1.38 ===
	* EXPERIMENTAL: The environment variable MW_CONFIG_FILE can be used to specify
	the location of the settings file. This allows alternative settings files to
	be loaded depending on the environment. Settings files may be given as PHP
	files like the traditional LocalSettings.php file, or they may use JSON or
	YAML format.
	See https://www.mediawiki.org/wiki/Manual:YAML_settings_file_format
	* Added a deleteUserEmail maintenance script - This file enables the deletion of
	a given user's associated email address. It can be helpful for
	privacy-preserving operations.
	* The description array for constructing an HTMLForm now can use 'disable-if' to
	disable fields on condition easily, supported expressions are the same as
	'hide-if'.
	* There is a new interface, IForeignRepoWithMWApi, to allows you to mark file
	repos provided by an extension as supporting making API queries against the
	foreign file repo so that extensions like TimedMediaHandler that depend on
	this can stop hard-coding looking for specific class names.
	* Added EXPERIMENTAL support for an easy to configure multi-tenant ("wiki
	farm") mode:
	Settings for each site can be placed in a directory specified by
	$wgWikiFarmSettingsDirectory. Site detection is controlled by
	$wgWikiFarmSiteDetector and defaults to the requested host name.
	For example, setting $wgWikiFarmSettingsDirectory = "sites" would cause
	the settings for wiki.example.com to be loaded from
	"sites/wiki_example_com.yaml".
	WARNING: YAML files under the web root may be accessible to browsers, please
	take appropriate measures to protect them from access via HTTP.
	* Running QUnit tests for an individual test suite module is possible with

	balanced HTML.
	* EventRelayerKafka was deprecated. To use $wgEventRelayerConfig with Kafka,
	add a similar class to your code.

	* The PageArchive class has had several methods deprecated. The replacements are
	as follows:
	- Use UndeletePage instead of ::undeleteAsUser(), ::getFileStatus() and

	$wgBaseDirectory is preferred.
	Application logic should use the BaseDirectory setting from the main config.
	Tests and framework code that need to function without MediaWiki being
	fully initialized should use the MW_INSTALL_PATH constant.
	* The global function wfWikiID(), deprecated since 1.35, now emits deprecation
	warnings.
	* AbstractBlock::getBy() now takes a wikiId as a parameter and emits deprecation
	warnings in case of cross-wiki accesses.

	`bindToggleOnSpaceEnter` has also been deprecated in favor of
	`bindToggleOnEnter`.
	* IDatabase::lockTables() and IDatabase::unlockTables() have been deprecated
	with no replacement. Instead, callers should batch updates into atomic
	transactions, using FOR UPDATE for SELECT queries.
	* EditPage::addNewLineAtEnd() was deprecated; use
	TextboxBuilder::addNewLineAtEnd instead.
	* EditPage::getCopywarn() was deprecated; use EditPage::getCopyrightWarning
	instead.
	* EditPage::getCopyrightWarning() without passing a MessageLocalizer parameter
	has been deprecated.
	* Passing the $formCallback parameter to EditPage::showEditForm, deprecated in
	1.25 and previously emitting a warn notice, now emits a deprecation notice.
	* EditPage::$action has been deprecated.
	* The following properties in EditPage now emit deprecation notices when used
	from another class:
	- mArticle (use ::getArticle() instead)
	- mTitle (use ::getTitle() instead)
	- isNew (no replacement)
	- allowBlankArticle (no replacement)
	- selfRedirect (no replacement)
	- allowSelfRedirect (no replacement)
	- diff (no replacement)
	- textbox2 (no replacement)
	- undoAfter (no replacement)
	- edit (no replacement)
	- contentLength (no replacement)
	* The HTMLForm methods getPreText, setPreText, addPreText, getPostText,
	setPostText, addPostText, getHeaderText, setHeaderText, addHeaderText,
	getFooterText, setFooterText and addFooterText have been renamed to
	getPreHtml, setPreHtml, addPreHtml, getPostHtml, setPostHtml, addPostHtml,
	getHeaderHtml, setHeaderHtml, addHeaderHtml, getFooterHtml, setFooterHtml and
	addFooterHtml respectively.
	* The FormSpecialPage methods preText and postText have been renamed to preHtml
	and postHtml respectively.
	* Article::doDelete, deprecated in 1.37, now emits deprecation notices.
	* The following Less mediawiki.mixins have been deprecated:
	- .background-image()
	- .list-style-image()
	* Category::getPageCount now takes a parameter. Category::COUNT_ALL_MEMBERS
	return count of all members while Category::COUNT_CONTENT_PAGES return that
	of content pages. For the former behavior use Category::getMemberCount()
	* Using `new HTMLForm( … )` or `HTMLForm::factory( … )` without the $context
	parameter is now deprecated.
	* BagOStuff::incr() and BagOStuff::decr() are now deprecated.
	* Action::exists() and ActionFactory::actionExists() are deprecated, use
	(bool)ActionFactory::getAction().

	=== Other changes in 1.38 ===
	* The following things were changed in the file deletion form:
	- The name and ID of the submit button are now `wpConfirmB`, not
	`mw-filedelete-submit`
	- The ID of the form is now `deleteconfirm`, not `mw-img-deleteconfirm`
	- The `mw-filedelete-editreasons` class was replaced with
	`mw-delete-editreasons`
	The goal of these changes is to make the HTML more similar to that of
	normal page deletion.
	* ParserOptions created with ::newFrom* or ::newCanonical are now identical.
	* MediaWiki initialization order have been changed to load vendor autoload
	earlier. This means that extensions that are installed via composer and
	execute code upon autoloading can not depend on any MediaWiki classes,
	constants or globals in that code.
	* The source of truth for configuration defaults is now the MainConfigSchema
	class. DefaultSettings.php still exists for backwards compatibility. A PHP
	file generated for optimized loading will be used in Setup.php to initialize
	configuration variables. Setup.php can be made to load DefaultSettings.php
	as before by setting MW_USE_LEGACY_DEFAULT_SETTINGS as an environment
	variable (e.g. via SetEnv in htaccess) or a PHP constant (e.g. via
	auto_prepend_file in php.ini).

	== Compatibility ==
	MediaWiki 1.38 requires PHP 7.3.19 or later and the following PHP extensions:

	* ctype
	* dom
	* fileinfo
	* iconv
	* intl
	* json
	* mbstring
	* xml

	MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
	but support for them is somewhat less mature.

	The supported versions are:

	* MySQL 5.5.8 or later
	* PostgreSQL 9.4 or later
	* SQLite 3.8.0 or later

	== Online documentation ==
	Documentation for both end-users and site administrators is available on
	MediaWiki.org, and is covered under the GNU Free Documentation License (except
	for pages that explicitly state that their contents are in the public domain):

	https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation

	== Mailing list ==
	A mailing list is available for MediaWiki user support and discussion:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

	A low-traffic announcements-only list is also available:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

	It's highly recommended that you sign up for one of these lists if you're
	going to run a public MediaWiki, so you can be notified of security fixes.

	== Upgrading notes for 1.37 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.27.

	Some specific notes for MediaWiki 1.37 upgrades are below:
	* (T280806) Deprecated methods of fetching API tokens have been removed. This
	may cause older bots and scripts to fail. Most queries are trivially
	updateable to using new methods. See the Action API changes section below
	for more information.

	For notes on 1.36.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.37 ===
	* (T242768) The PasswordCannotMatchUsername password policy has been removed,
	please use PasswordCannotBeSubstringInUsername instead. If you have not
	customised your password policies, there will be nothing to do here.

	==== New configuration ====
	* $wgBrowserFormatDetection - This setting allows the enabling or disabling
	of automatic detection of possible phone numbers in a webpage in iOS Safari.
	* $wgParserEnableLegacyMediaDOM - This setting defaults to true, and enables
	the legacy media HTML structure in the output from the Parser. The
	alternative modern HTML structure for media is described at
	https://www.mediawiki.org/wiki/Parsing/Media_structure
	In a future release of MediaWiki this option will default to false,
	so it's a good idea to test this setting on your wiki early and report
	any issues.

	==== Changed configuration ====
	* $wgContentHandlerTextFallback - This migration setting, which defines how to
	react if a plain text version of a non-text Content object is requested using
	ContentHandler::getContentText(), is deprecated.
	* $wgActions – This setting lets sysadmins over-ride which actions can be used.
	It has been re-worked to support injecting dependencies into Action sub-
	classes as part of wider work on dependency injection. Previously, $wgActions
	was an array where the keys were the names of actions, and the values had the
	following impacts (for a given key 'Foo'):
	- `true`: use the class 'FooAction' unless for a specific page
	WikiPage::getActionOverrides() wants to override that action
	- a string: use the class with that name, and do not allow over-riding on a
	per-page basis
	- `false`: the action is disabled
	- a callable: use the Action instance returned by invoking that callback, and
	do not allow overriding on a per-page basis
	- an object: use that specific Action instance, and do not allow overr-iding
	on a per-page basis.
	As part of T253078, values can now be arrays that are not callables, which are
	treated as ObjectFactory specs, allowing for services to be injected.
	Additionally, the distinction between values that allow per-page overrides and
	those that do not was removed - all actions can now be overridden on a per-
	page basis using WikiPage::getActionOverrides().
	* $wgShellboxUrl – This setting, new in 1.36 to configure the novel Shellbox
	encapsulation system, is now deprecated; use $wgShellboxUrls as a mapping of
	service => URL instead.
	* $wgIncludejQueryMigrate – This setting, introduced in 1.29 to on whether to
	provide a migration layer for jQuery, has now switched its default value from
	true to false. This may break gadgets that depended on methods that were
	removed in jQuery 3 in 2017. See T280944 for more information.
	* A number of settings have been renamed. The former configuration variable
	names are deprecated, but will be used as the fall back if they are still set,
	and remain temporarily available for extensions which might try to read them:
	- $wgFileBlacklist is now $wgProhibitedFileExtensions
	- $wgMimeTypeBlacklist is now $wgMimeTypeExclusions
	- $wgEnableUserEmailBlacklist is now $wgEnableUserEmailMuteList
	- $wgShortPagesNamespaceBlacklist is now $wgShortPagesNamespaceExclusions
	* $wgMimeTypeExclusions - As well as being renamed, this configuration array now
	also prohibits the RFC 4329 form of JavaScript, 'application/javascript', as
	well as previous MIME types.
	* $wgFragmentMode - This setting, which determines the encoding of section IDs,
	has now switched its default value from legacy-first to html5-first: both the
	HTML5 anchor and the legacy percent-encoding-style anchor will still be
	generated for section titles, but references to them will use the HTML5
	version, resulting in human-readable fragments.

	==== Removed configuration ====
	* $wgLegacyJavaScriptGlobals, deprecated in 1.36.
	* (T274695) $wgAjaxEditStash, deprecated in 1.36.
	* $wgShowDBErrorBacktrace, deprecated and non-functional since 1.32.
	* $wgShowSQLErrors, deprecated and non-functional since 1.32.
	* $wgLangObjCacheSize, without deprecation; the LanguageFactory service now
	always retains at most 10 objects in its LRU-cache.
	* $wgDjvuToXML, without deprecation; the tool it enables is obsolete and
	abandoned upstream. Use $wgDjvuDump to use that tool instead.

	=== Breaking changes in 1.37 ===
	* The Revision class, emitting deprecation warnings since 1.35, was removed
	entirely. As part of this, the following hooks that included a Revision object
	were removed:
	- ArticleRevisionUndeleted - use RevisionUndeleted
	- ArticleRollbackComplete - use RollbackComplete
	- DiffRevisionTools - use DiffTools
	- DiffViewHeader - use DifferenceEngineViewHeader

	- NewRevisionFromEditComplete - use RevisionFromEditComplete
	- PageContentInsertComplete - use PageSaveComplete
	- PageContentSaveComplete - use PageSaveComplete
	- ParserFetchTemplate - use BeforeParserFetchTemplateRevisionRecord
	- RevisionInsertComplete - use RevisionRecordInserted
	- TitleMoveComplete - use PageMoveComplete
	- TitleMoveCompleting - use PageMoveCompleting
	- UndeleteShowRevision - no replacement
	- UserRetrieveNewTalks - no replacement
	… the following methods and variables have been removed:
	- Article::$mRevision
	- Article::getRevisionFetched()
	- ContribsPager::tryToCreateValidRevision()
	- EditPage::$mBaseRevision
	- EditPage::getBaseRevision()
	- LinksUpdate::getRevision()
	- LinksUpdate::setRevision()
	- PageArchive::getArchivedRevision()
	- PageArchive::getPreviousRevision()
	- PageArchive::getRevision()
	- Parser::$mRevisionObject
	- Parser::fetchCurrentRevisionOfTitle()
	- Parser::getRevisionObject()
	- Parser::statelessFetchRevision()
	- ParserOptions::getCurrentRevisionCallback()
	- ParserOptions::setCurrentRevisionCallback()
	- Title::countAuthorsBetween()
	- Title::getFirstRevision()
	- User::getNewMessageLinks()
	- User::getNewMessageRevisionId()
	- User::setNewtalk()
	- WikiPage::getOldestRevision()
	- WikiPage::getRevision()
	- WikiPage::getUndoContent()
	- WikiPage::updateIfNewerOn()
	… and the following methods no longer accept Revision objects as parameters:
	- CategoryMembershipChange::__construct()
	- ContentHandler::getUndoContent()
	- DerivedPageDataUpdater::prepareUpdate()
	- DifferenceEngine::getRevisionHeader()

	- WikiPage::doEditUpdates()
	- WikiPage::hasDifferencesOutsideMainSlot()
	- WikiPage::onArticleEdit()
	- WikiPage::prepareContentForEdit()
	- WikiPage::updateRevisionOn()
	The following methods return arrays that formerly included a 'revision'
	key that would emit deprecation warnings when accessed and return a
	Revision object. The Revision object has been removed from the arrays,
	and the 'revision-record' key should be used to get the relevant
	RevisionRecord instead:
	- PageUpdater::doCreate()
	- PageUpdater::doModify()
	- Parser::statelessFetchTemplate()
	- WikiPage::doEditContent()
	Finally, the ParserOptions `templateCallback` option is a callback that is
	called in Parser::fetchTemplateAndTitle() and should return an array - the
	'revision' key to that array used to be a Revision object and was used if
	no 'revision-record' was returned - is now ignored.
	* Previously, the classes RevisionTestModifyableContent and
	RevisionTestModifyableContentHandler were loaded for use in tests, but were
	only used within the tests for the since-removed Revision class. This content
	and content handler class were removed without deprecation.
	* WANObjectCache::HOLDOFF_NONE, deprecated since 1.35, was removed. Use
	WANObjectCache::HOLDOFF_TTL_NONE instead.

	handler without changing the status, the edit form will now be displayed.
	* User::clearNotification() which had been deprecated in 1.35 has been removed.
	Use WatchlistManager::clearTitleUserNotification() instead.
	* User::getNewtalk() which had been deprecated in 1.35 has been removed. Use
	TalkPageNotificationManager::userHasNewMessages() instead.
	* The Autopromote class, deprecated since 1.35, was removed. Use
	UserGroupManager instead.
	* The CachedAction, SpecialCachedPage, CacheHelper, and ICacheHelper classes,
	all emitting deprecation warnings since 1.36, have been removed.

	in 1.35, were removed.
	* The TitleArrayFromResult hook, deprecated in 1.36, was removed.
	* The deprecated "es6-promise" alias ResourceLoader module has been removed. Use
	the "es6-polyfills" module directly intead.
	* The deprecated "mediawiki.legacy.protect" ResourceLoader module, deprecated
	since 1.36, has been removed. Use "mediawiki.action.protect" instead.
	* The JavaScript alias $j for references to jQuery, deprecated since 1.23, has
	been removed. Use $ instead.
	* The AuthenticationProvider interface and the SessionProvider class no longer
	extend the PSR LoggerAwareInterface concept, so they can't be typehinted as
	LoggerAwareInterface.
	* User::getGrantName(), emitting deprecation warnings since 1.36, has been
	removed. Use MWGrants::grantName() instead.
	* The following ApiBase methods, deprecated since 1.35, have been removed:
	- ApiBase::explodeMultiValue
	- ApiBase::parseMultiValue
	- ApiBase::validateLimit
	- ApiBase::validateTimestamp

	Instead of using it, get a UserIdentity by name from the UserIdentityLookup
	service.
	* IDatabase::upsert() and IDatabase::replace() now only accept a single unique
	key. Previously, a warning was issued if there were multiple unique keys
	provided.
	* The MediaWiki:Autoblock_whitelist block exemption control was moved in 1.36 to
	MediaWiki:Block-autoblock-exemptionlist. The backward-compatibility of reading
	the old MediaWiki:Autoblock_whitelist page has now been dropped.

	- use-filebackend => PHPUNIT_USE_FILEBACKEND
	- use-bagostuff => PHPUNIT_USE_BAGOSTUFF
	- use-jobqueue => PHPUNIT_USE_JOBQUEUE
	This is so that we can use the default PHPUnit entry point (T90875).
	* The PHPUNIT_REUSE_DB / --reuse-db option was removed from the phpunit.php
	runner. It had been broken for at least three years already. The original use
	case was speeding up tests on Oracle, but Oracle support was dropped several
	releases ago.
	* The MediaWikiPHPUnitTest__endTestHook and MediaWikiPHPUnitTest__startTestHook
	PHPUnit hooks were removed. MediaWikiHooksPHPUnitExtension was also removed.
	* EntryPoint::getTextFormatters() was made private without a deprecation period;

	* ActorMigrationBase::getExistingActorId() and ::getNewActorId(), emitting
	deprecation warnings since 1.36, were removed.
	* Hook handlers implementing the MediaWikiServicesHook hook are now prohibited
	from having services injected. This is because by definition, this hook runs
	before the service container is fully initialized.
	* The protected property LocalFile::$metadata was removed without deprecation.
	* WatchedItem::getUser(), emitting deprecation warnings since 1.36, has been
	removed.
	* AuthManager::singleton(), emitting deprecation warnings since 1.36, has been
	removed.
	* The AugmentPageProps class was removed without deprecation. It had no known
	uses.
	* Html::infobox(), deprecated since 1.36, was removed.
	* ParserOptions::__construct() now requires that the first parameter is a
	UserIdentity object - passing `null` used to fallback to the global
	$wgUser but was deprecated since 1.36.
	* ParserOptions::newCanonical() no longer supports the first parameter being
	null (or omitted entirely), which would fallback to the global $wgUser but
	was deprecated since 1.35.
	* The SkinTemplatePreventOtherActiveTabs hook, deprecated in 1.35, was removed
	entirely.
	* The SkinTemplateTabAction hook, deprecated in 1.35, was removed entirely.

	necessarily a User object. There is no known usages in MediaWiki ecosystem
	that were not satisfied with UserIdentity.
	* Direct construction of MergeHistory class, deprecated since 1.35, is no longer
	supported. Use MergeHistoryFactory instead. MergeHistory::checkPermissions,
	deprecated since 1.36, was removed.
	* Skin::generateDebugHTML(), deprecated since 1.35, was removed. Call
	MWDebug::getHTMLDebugLog() directly.
	* The ApiTestCase class no longer interacts with the global $wgUser.
	Previously, the global variable was set at the start of each test, and in
	ApiTestCase::doApiRequest() if a performer was specified $wgUser was
	updated to match, and if no performer was specified $wgUser was used
	instead. Now, $wgUser is not updated, and if no performer is specified
	the reusable TestUser object for the sysop is relied on. Extensions
	or skins that rely on the global $wgUser variable (which has been
	deprecated since 1.35) should instead retrieve the acting user from the
	relevant context source.
	* SkinTemplate::makeArticleUrlDetails(), deprecated since 1.35, was removed.
	* Skin::makeNSUrl(), deprecated since 1.35, was removed.
	* Skin::getRevisionId(), deprecated since 1.34, was removed. Use
	OutputPage::getRevisionId() instead.

	OutputPage::isRevisionCurrent() instead.
	* AbstractBlock::parseTarget(), deprecated since 1.36, was removed.
	* The ArticleEditUpdates hook, deprecated since 1.35, was removed.

	User instance.
	- A number of its `@stable to override` methods now accept an Authority
	instead of a User instance as the $audience parameter.
	- A number of methods now accept a UserIdentity instead of their User
	parameter.
	- The ::localUserFromCentralId() method now returns UserIdentity and not
	necessarily a User object.
	All extensions that extend this class or use this method were updated to be
	ready to the new behavior.
	* WatchedItemStoreInterface::enqueueWatchlistExpiryJob(), deprecated since 1.36,
	was removed.
	* ResultWrapper is now abstract. It cannot be directly constructed (T286694).
	* The SecondaryDataUpdates hook, deprecated in 1.32, was removed entirely.

	* Language::$mLangObjCache, deprecated since 1.35, was removed.
	* Language::$transformData, deprecated since 1.35, was removed.

	made private.
	* The Skin::setupSkinUserCss() method, deprecated in 1.32, was removed. Please
	use skin registration instead.
	* The ResourceLoaderSkinModule `legacy`, `content` and `content-thumbnails`

	* The BaseTemplateToolbox hook, deprecated since 1.35, was removed.
	* Previously a capitalize-all-nouns class was added to the body element of
	languages where nouns must be capitalized. This class is no longer added to
	the body tag and must be provided by skins.
	* The SkinTemplateOutputPageBeforeExec hook, deprecated since 1.35, was removed.
	* Calling Message::toString() without a parameter, which triggered deprecation
	warnings since 1.36, is no longer supported. You can instead use the explicit
	formatting methods directly, such as Message::text() and Message::escaped().
	* Article::getContentObject(), deprecated since 1.32, was removed.
	* Article::delete(), Article::confirmDelete() and ImagePage::delete() were
	removed. The logic responsible for building the form is being
	moved to DeleteAction, while the actual deletion logic will be moved to a
	separate service.
	* WikiImporter::debugRevisionHandler(), unused and for debug only, was removed.
	* Content::preloadTransform() now emits deprecation warnings. Instead, please
	use ContentTransformer::preloadTransform(). Extensions defining a content
	model should override ContentHandler::preloadTransform().
	* Content::preSaveTransform() now emits deprecation warnings. Instead, please
	use ContentTransformer::preSaveTransform() instead. Extensions defining
	a content model should override ContentHandler::preSaveTransform().
	* Constructing WikiPage objects from Title instances that cannot exist, emitting
	deprecation warnings since 1.36, now throws an exception. Additionally,
	WikiPage now implements ProperPageIdentity, rather than just PageIdentity.
	* The Skin::bottomScripts() method is deprecated. Please instead use

	1.36, was removed. Use CSS property `box-shadow` unprefixed for all basic
	supported browsers instead.
	* The LESS mixin `.flex()` now no longer tries to support the 2009 version of
	the Flexbox specification; support for the 2012 and modern standard versions
	remains unchanged.
	* The StorageAwareness::ATTR_SYNCWRITES, StorageAwareness::QOS_SYNCWRITES_*,
	StorageAwareness::ATTR_LOCALITY, and StorageAwareness::QOS_LOCALITY_*
	constants were removed.

	* JobQueueGroup::destroySingletons() was deprecated. JobQueueGroups are now

	* User::getRights(), deprecated since 1.34, now emits deprecation warnings.
	* User::changeableGroups() and ::changeableByGroup() now emit deprecation
	warnings, use corresponding methods in UserGroupManager instead.

	* The following constructor options of DatabaseBlock class will now trigger
	deprecation warnings:
	- the 'byText' property with blocker's name,

	For both of these, use the 'by' property with UserIdentity value instead.
	* The BeforeResetNotificationTimestamp hook was deprecated.
	* ArchivedFile::getUser() ::getRawUser() ::getRawUserText() were deprecated in
	favor of ::getUploader.() ::getRawDescription() was deprecated in favor of
	::getDescription() with RAW audience parameter.

	extra fields not requested by ::getQueryInfo() will now trigger deprecation
	warnings. This is to warn callers that deprefixing and automatic assignment of
	such fields will not be done in a future version.
	* JobSpecification::getTitle() was deprecated without providing a replacement.
	It wasn't used and job given the purpose of JobSpecification class it is not

	BaseTemplateAfterPortlet hook, which were deprecated in 1.35,
	now emit deprecation warnings.
	* The LocalFile::getHistory() hook is deprecated.
	* Previously the Skin templateDirectory option inside skin.json had to be
	relative to MediaWiki core. This should now be relative to the skin.
	* Calling WikiPage::prepareContentForEdit() without a UserIdentity is now

	deprecated. Use CsrfTokenRepository, which is available via IContextSource,
	instead. ::matchEditTokenNoSuffix() was deprecated without replacement.
	It was introduced to be able to provide custom error message if the token
	was submitted, but ending slashes were stripped by some ASCII mangling proxy.

	not much benefit in customising the error message.

	warnings.
	* User::listOptionKinds(), deprecated since 1.35, now emits deprecation
	warnings.

	- WikiPage::isBatchedDelete() (soft) - use DeletePage
	- WikiPage::doDeleteUpdates() (hard) - no replacement
	- WikiPage::getDeletionUpdates() (hard) - no replacement

	* User::isAllowUsertalk() now emits deprecation warnings. Use User::getBlock()
	and AbstractBlock::isUsertalkEditAllowed() instead.
	* Classes used by Preprocessor_DOM have been merged with classes used by
	Preprocessor_Hash, as Preprocessor_DOM was removed in 1.35.
	- PPDPart has been merged into PPDPart_Hash
	- PPDStack has been merged into PPDStack_Hash
	- PPDStackElement has been merged into PPDStackElement_Hash
	* By default, the global variable $wgUser is now an instance of the new class
	StubGlobalUser rather than User, and the first time it is used it will emit
	deprecation warnings (the $wgUser variable was deprecated in 1.35). For
	extensions that read from this variable, please use a relevant ContextSource
	instead, falling back to RequestContext::getMain() if none is available.

	PageArchive object has been removed, as that violates the laws of nature.

	=== Other changes in 1.37 ===
	* WatchlistManager::addWatch() and WatchlistManager::addWatchIgnoringRights(),
	which replace User::addWatch(), now call the WatchArticle and
	WatchArticleComplete hooks.

	renamed to 'mw-htmlform-autoinfuse'.

	$data['user_properties'] anymore. This optimization was not used.
	* The following files change the letter case of the file names:
	- SpecialRandompage.php -> SpecialRandomPage.php
	- SpecialRandomredirect.php -> SpecialRandomRedirect.php
	- SpecialRandomrootpage.php -> SpecialRandomRootPage.php

	maintenance script will now have the "mw-server-side-upload" change tag.

	* HTMLTitleTextField didn't support interwiki titles well previously.
	Starting with 1.37, HTMLTitleTextField has a new parameter, 'interwiki',

	a transitional period, the default value ('interwiki' => null) ensures
	MW will have the same behavior as before (logging a deprecation warning).
	In 1.38, the default behavior will change to "interwiki links aren't allowed".

	== Compatibility ==

	* (T282594) Timeless: Re-branch to 40eb3dad1for REL1_36.

	== MediaWiki 1.36.0-rc.0 ==

	== Upgrading notes for 1.36 ==
	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed per-version upgrade instructions from the
	oldest supported upgrading version, MediaWiki 1.27.

	Some specific notes for MediaWiki 1.36 upgrades are below:
	* MediaWiki 1.36 now requires the PHP internationalization extension (commonly
	referred to as Intl, ext-intl, or php-intl).
	* The MediaWiki:Autoblock_whitelist block exemption control has been moved to
	MediaWiki:Block-autoblock-exemptionlist. If you use this feature, please move
	the MediaWiki:Autoblock_whitelist page.
	* (T275334) $wgExtensionFunctions is sometimes used to change configuration
	settings. This is not safe; extension functions are run relatively late, some
	services are already initialized by that point and so they use the old
	configuration. Changes in 1.36 make this kind of breakage even more common.
	You can use the MediaWikiServices hook instead. (In the future there might be
	a dedicated hook for configuration changes.)

	For notes on 1.35.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.36 ===
	The MediaWiki update script, maintenance/update.php, used to accept `--nopurge`
	as an option to prevent clearing caches stored in the database during upgrade.
	This is no longer encouraged, and the option has been removed.

	==== New configuration ====
	* (T256001) $wgManualRevertSearchRadius – This setting controls a new feature
	that marks edits as reverts if they restore the page to an exact previous
	state. This configuration variable sets the maximum number of revisions of a
	page that will be checked against every new edit. Set this to 0 to disable the
	feature entirely.
	* (T244058) $wgOldRevisionParserCacheExpireTime — This setting was added to
	control caching of ParserOutput for old (non-current) revisions.
	* (T265263) $wgRememberMe - This setting configures the "remember me" checkbox
	on account log-in systems via RememberMeAuthenticationRequest.
	* (T157145) $wgSkinMetaTags – This setting lets sysadmins configure skins that
	support meta tags. These tags make sharing of MediaWiki pages on a variety of
	social platforms more contentful and thus useful.
	* (T280944) $wgIncludejQueryMigrate - This setting lets sysadmins disable the
	jQuery Migrate plugin. It has been enabled by default since MediaWiki 1.27.
	In future releases it will be disabled by default.

	==== Changed configuration ====
	* $wgLogos – This setting selects the logo shown on the site. The default value
	for the site logo, which is shown in an install if you have not set one, will
	now be the new logo of MediaWiki.
	* (T274695) $wgAjaxEditStash — This setting, to disable the edit stashing
	feature when users start writing an edit summary, has been deprecated. In
	future releases, this feature will always be enabled.
	* $wgUploadStashScalerBaseUrl – This setting, to enable remote on-demand media
	scaling, was deprecated. Use the `thumbProxyUrl` setting in $wgLocalFileRepo
	instead.
	* $wgSlaveLagWarning and $wgSlaveLagCritical – These settings have been renamed,
	to $wgDatabaseReplicaLagWarning & $wgDatabaseReplicaLagCritical respectively.
	The former configuration variable names are deprecated, but will be used as
	the fall back if they are still set, and remain temporarily available for
	extensions which try to read them.
	* $wgWANObjectCaches - The "coalesceKeys" option was removed without deprecation
	and replaced by a new "coalesceScheme" option, set to "hash_stop" by default.
	If you use Dynomite, then set the new "coalesceKeys" option to "hash_tag". The
	"cluster" and "mcrouterAware" options were also removed without deprecation.
	Use "broadcastRoutingPrefix" instead.

	==== Removed configuration ====
	* $wgUseTwoButtonsSearchForm — This setting, deprecated in 1.35, has been
	removed.
	* $wgAllowImageMoving — This setting, deprecated in 1.35, has been removed. Use
	group permission settings instead. For example, to prevent sysops from
	moving files, set `$wgGroupPermissions['sysop']['movefile'] = false;`
	* $wgExtNewTables, $wgExtNewFields, $wgExtNewIndexes, $wgExtPGNewFields,
	$wgExtPGAlteredFields, $wgExtModifiedFields — These settings were removed.
	They became obsolete after 1.17 overhauled the database updater, but were kept
	for backwards compatibility. The LoadExtensionSchemaUpdates hook should be
	used instead.
	* $wgParserConf - This setting, deprecated in 1.35, has been removed. The last
	use of this setting was for pre-processor configuration, which was deprecated
	in 1.34 and removed in 1.35.
	* $wgEnableRestAPI - This setting, ignored since 1.35, has been removed.
	* $wgPagePropsHaveSortkey – This temporary setting has been removed, along with
	the schema change upgrade path it controlled. If your site is still using it,
	meaning you have not yet applied the `pp_sortkey` schema change from 1.24, you
	must now apply it before upgrading.
	* The deprecated password policies PasswordCannotMatchBlacklist and
	PasswordNotInLargeBlacklist were removed. Please use
	PasswordCannotMatchDefaults and PasswordNotInCommonList respectively instead.

	=== New user-facing features in 1.36 ===
	* The logo of MediaWiki has changed. This means that the "Powered By MediaWiki"
	button shown in the skin footer will be different.
	* All HTML5 named entities are now accepted in wikitext.
	* (T106263) The file description page's alternate sizes now include 2048px.

	=== New developer features in 1.36 ===
	* Parser test files can now declare a dependency on a specific extension being
	loaded, not just on the presence of a certain extension tag hook. This is a
	better fit for extensions like TimedMediaHandler, which affect the output but
	don't register parser hooks. Use `extension:Foo` in the `!! hooks` section of
	your parser test file to declare a dependency on the `Foo` extension being
	loaded.
	* To expose code previously present in SpecialBlock/SpecialUnblock to other
	parts of the code, or to extensions, the new BlockUser and UnblockUser command
	objects were added. Use the BlockUserFactory and UnblockUserFactory services
	to create them.
	* The hook UsersPagerDoBatchLookupsHook takes now a \Wikimedia\Rdbms\IDatabase,
	instead of \Wikimedia\Rdbms\DBConnRef, as the first parameter.
	* MediaHandlers can now customize the formatting of the metadata they emit by
	over-riding MediaHandler::formatTag( $key, $value ). The default for unknown
	tags is numeric formatting; non-EXIF tags which are non-numeric should always
	use this method to specify the desired formatting.
	* The new 'title' type can be used to validate action API and REST API inputs.
	* The new ArticleParserOptions hook allows customizing the parser options used
	to parse wikitext for an article, based on user preferences, title, etc.
	* The new 'raw' type can be used to validate action API inputs. It bypasses the
	Unicode NFC normalization done on inputs of type 'string', so it more suitable
	when the input is binary or may contain deprecated Unicode sequences or
	characters (such as U+2001) that should be passed unmodified.
	* (T260330) A new abstraction for running shell commands has been introduced,
	called BoxedCommand. A BoxedCommand object can be obtained with
	MediaWikiServices::getInstance()->getCommandFactory()->createBoxed().
	* ResourceLoader modules can now mark themselves as ES6-only by setting
	`'es6' => true` in their module definition. ES6-only modules will not be
	executed in browsers that don't support ES6, such as IE11.

	* The wikimedia/avro suggested development-only library has been removed, as the
	support for logging in Avro format has been dropped.

	=== Bug fixes in 1.36 ===
	* (T190285) ApiEditPage module used to switch 'undo' and 'undoafter' parameters,
	if it founds you reversed them (based on assumption that higher revision ID
	indicates a later revision). The assumption is not always true, and is
	hindering proper edit undoing in some cases, hence the logic has been removed.
	Reversing the parameters will now lead to edit conflict or undefined behavior.
	* (T263340) In history merging, pages with a content model that does not support
	redirects will now be recorded as deleted if no revision is being left in the
	source page (that's if all revisions of the page have been merged to another).

	=== Action API changes in 1.36 ===
	* (T269636) `Access-Control-Max-Age` was added to the default list of headers
	allowed for cross-origin API requests ($wgAllowedCorsHeaders).
	* (T258108) Accounts with the 'bot' right no longer have pages automatically
	added to the watchlist when making API edits, regardless of their preferences.
	This is to reduce the size of the watchlist data in the database. To add API
	bot edits to the watchlist, explicitly set the 'watch' option.

	=== Languages updated in 1.36 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* (T258975) Added a Latin/Cyrillic script converter for the Talysh language.
	* (T245359) Split Bali script locale from "ban" (Balinese) (ban-bali).
	* (T264582) Added language support for Madurese (mad).
	* (T259330) Added language support for Mara (mrh).
	* (T263968) Added language support for Nias (nia).
	* (T270365) Added language support for Tyap (kcg).
	* (T276745) Added language support for Wayuu (guc).

	=== Breaking changes in 1.36 ===
	* Grade C (non-JavaScript) support for Internet Explorer 8 has been dropped.
	* (T249459) wfIsBadImage(), deprecated in 1.34, has been removed.
	* (T176526) EditPage::getContextTitle() will now throw an exception if a context
	title was not set using setContextTitle(). Previously, this mis-use would only
	cause a deprecation warning to be emitted.
	* The DeferredStringifier class, deprecated since 1.31, was removed.
	* Multiple methods that fell back to the $wgUser global variable were
	individually hard deprecated previously. The following have now been removed:
	- ApiTestCase::doLogin
	- Article::doDeleteArticle
	- Article::doDeleteArticleReal
	- Article::getComment
	- Article::getCreator
	- Article::getUser
	- Article::getUserText
	- Article::insertProtectNullRevision
	- File::delete
	- File::recordUpload
	- ForeignDBFile::delete
	- ForeignDBFile::recordUpload
	- LocalFile::delete
	- LocalFile::deleteOld
	- LocalFile::recordUpload
	- PageArchive::undelete
	- RecentChange::markPatrolled
	- Title::getUserPermissionsErrors
	- Title::quickUserCan
	- Title::userCan
	- WebRequest::getLimitOffset
	- WikiPage::doDeleteArticle
	- WikiPage::insertProtectNullRevision
	* The SpecialPageFactory class, deprecated in 1.32, has been removed. Use the
	SpecialPageFactory service instead.
	* Multiple methods previously had optional User parameters, with fallbacks
	to the $wgUser global variable. Not passing a User to those methods was
	previously hard deprecated, and support for not passing a User has now
	been removed:
	- ArchivedFile::userCan
	- File::userCan
	- FileDeleteForm::__construct
	- FileDeleteForm::doDelete
	- LocalFileDeleteBatch::__construct
	- LogEventsList::getExcludeClause (only needed for the 'user' audience)
	- LogEventsList::userCan
	- LogEventsList::userCanBitfield
	- LogEventsList::userCanViewLogType
	- LogPage::addEntry (also accepts user id instead)
	- OldLocalFile::userCan
	- PatrolLog::record
	- Title::getNotificationTimestamp (though the entire method is deprecated)
	- WikiPage::getComment (only needed for the FOR_THIS_USER audience)
	- WikiPage::getCreator (only needed for the FOR_THIS_USER audience)
	- WikiPage::getUser (only needed for the FOR_THIS_USER audience)
	- WikiPage::getUserText (only needed for the FOR_THIS_USER audience)
	* The following hooks have been removed:
	- APIQueryInfoTokens
	- APIQueryRecentChangesTokens
	- APIQueryRevisionsTokens
	- APIQueryUsersTokens
	- ApiTokensGetTokenTypes
	* LogEventsList::typeAction previously accepted an optional right parameter, and
	checked if the context user ($wgUser) had that right. Passing a right was hard
	deprecated in 1.35, and support for passing a right has now been removed.
	* WikiPage::doDeleteArticleReal previously accepted an optional user as its
	fifth parameter, and fell back to $wgUser if not user was provided. The
	signature changed to have the user as the second parameter, and the old
	signature was hard deprecated in 1.35. Support for the old signature has now
	been removed.
	* User::addNewUserLogEntry, deprecated since 1.27, was removed.
	* As part of refactoring the EditPage class, EditPage::setPreloadedContent,
	which had no known callers was removed entirely. Additionally, the following
	public methods were made private:
	- ::extractSectionTitle
	- ::getSummaryInputWidget
	- ::noSuchSectionPage
	- ::initialiseForm
	* EditPage::matchSpamRegex and ::matchSummarySpamRegex, deprecated in 1.35,
	were removed. Use the SpamChecker service instead.
	* The global function `wfWaitForSlaves`, deprecated in 1.27 and hard-deprecated
	in 1.35, has been removed. Use LBFactory::waitForReplication() instead.
	* Calling Action::factory() with null as the first parameter, rather than a
	string, was deprecated in 1.35 and support was now removed.
	* Calling Action::factory() with an object that wasn't an Article as the second
	parameter was deprecated in 1.35 and support was now removed.
	* The global variable $wgMemc, deprecated since 1.35, has been removed. Usage
	should generally be migrated to WANObjectCache, or if you really need the
	internal object, use ObjectCache::getLocalClusterInstance instead.
	* The preprocessDump.php maintenance script was removed.
	* CategoryFinder, which was deprecated in 1.31 and hard-deprecated in 1.35,
	has been removed.
	* GenderCache::singleton(), which was deprecated in 1.28 and hard-deprecated
	in 1.35, has been removed.
	* Sanitizer::escapeId(), deprecated in 1.30, has been removed.
	* Direct invocation of Parser::__construct() (instead of via a ParserFactory)
	now throws an exception; support has also been removed for several
	deprecated variants on the arguments passed to Parser::__construct.
	Direct invocation of Parser::__construct was deprecated in 1.34.
	* Parser::setFunctionTagHook(), deprecated in 1.35, has been removed.
	* The following properties of Parser, deprecated in 1.35, have been made
	private:
	- $mTagHooks - use Parser::getTags()
	- $mFunctionHooks - use Parser::getFunctionHooks()
	- $mOutput - use Parser::getOutput()
	- $mPreprocessor - use Parser::getPreprocessor()
	* The ParserBeforeTidy hook, deprecated in 1.35, has been removed.
	* The ParserBeforeTidy, ParserBeforeStrip, and ParserAfterStrip hooks,
	deprecated in 1.35, have been removed.
	* All methods of MWTidy except for MW::tidy() have been removed. These were each
	either marked as @internal or deprecated in 1.35.
	* (T248062) Mixins `.background-image-svg()` and `.background-image-svg-quick()`
	(provided by mediawiki.mixins.less), which have been deprecated since 1.35,
	have now been removed. MediaWiki no longer supports any browser which would
	require this SVG-fallback PNG support, so you can simply use the regular CSS
	`background-image:` declaration instead.
	* The ResourceLoader module `mediawiki.legacy.oldshared` and its file
	'oldshared.css', deprecated since 1.35 has been removed (T248357).
	* `ResourceLoader::__construct` now requires a Config parameter. The optional
	nature of this parameter was deprecated in 1.34.
	* The LinkBegin and LinkEnd hooks, deprecated in 1.28, have been removed. You
	can instead use the HtmlPageLinkRendererBegin and HtmlPageLinkRendererEnd
	hooks, respectively.
	* The EmailUser hook passes its fifth param, $error, by reference, to allow
	hook handlers to add error messages, indicate that they have sent the email
	instead of core, etc. Setting the parameter to something other than a
	Status object, true, false, an empty string, an array, or a MessageSpecifier,
	object, which had been deprecated in 1.29, is no longer supported, and now
	results in an MWException being thrown.
	* Skin::getDynamicStylesheetQuery(), deprecated in 1.32, has been removed. You
	should use action=raw&ctype=text/css directly.
	* Skin::makeI18nUrl(), deprecated in 1.35, has been removed.
	* The following User methods, deprecated and moved to BlockManager in 1.34, were
	removed:
	- ::isDnsBlacklisted
	- ::inDnsBlacklist
	- ::isLocallyBlockedProxy
	- ::trackBlockWithCookie
	* Support for v1 of the parser tests file format has been removed; it was
	deprecated in 1.35. (T174199)
	* SpecialUnblockUser::processUIUnblock() now returns a Status object instead of
	an array of messages or a boolean value. This function was also marked as
	@internal and is no longer safe to call it publicly.
	* mw.Title.getDotExtension() from the 'mediawiki.Title' module was removed
	without deprecation. You should use mw.Title.getExtension() and prepend the
	dot if need be.
	* Profiler::getTemplated and Profiler::setTemplated, deprecated in 1.34, have
	been removed.
	* DatabaseMysqlBase now requires MySQL version 5.6.4+ when "lagDetectionMethod"
	is set to "pt-heartbeat".
	* Removed HookContainer::getOriginalHooksForTest() without deprecation. This
	method was introduced in 1.35 for internal use, and appears unused outside of
	MediaWiki core.
	* ParserCache::__construct() now requires three parameters.
	* Message->getFormat(), deprecated in 1.29, has been removed.
	* Support for passing Article to ParserCache::get, deprecated in 1.35, has been
	removed.
	* ParserCache::singleton(), deprecated in 1.30, has been removed.
	* DatabaseBlock::deleteIfExpired and ::fromMaster, deprecated in 1.35, have been
	removed.
	* Some deprecated AbstractBlock methods have been removed:
	- ::prevents, deprecated in 1.33
	- ::shouldTrackWithCookie, deprecated in 1.34
	- ::getBlocker, deprecated in 1.35
	- ::setBlocker, deprecated in 1.35
	- ::getBlockErrorParams, deprecated in 1.35
	* Multiple DatabaseBlock methods dealing with cookies, deprecated in 1.34,
	have been removed:
	- ::setCookie
	- ::clearCookie
	- ::getCookieValue
	- ::getIdFromCookieValue
	- ::shouldTrackWithCookie
	* The public static callback function SpecialUnblock::processUIUnblock has been
	removed. This method was for internal use only, and appears unused outside of
	MediaWiki core.
	* ChangeTags::truncateTagDescription, deprecated in 1.35, has been removed.
	* Deprecated null fallbacks in PasswordReset constructor have been removed.
	* User::isEveryoneAllowed and User::getAllRights, deprecated in 1.34, has been
	removed.
	* The following methods of the UserGroupMembership class, deprecated in 1.35,
	has been removed:
	- ::initFromRow
	- ::newFromRow - use UserGroupManager::newGroupMembershipFromRow
	- ::selectFields - use UserGroupManager::getQueryInfo
	- ::delete - use UserGroupManager::removeUserFromGroup
	- ::insert - use UserGroupManager::addUserToGroup
	- ::purgeExpired - use UserGroupManager::purgeExpired
	- ::getMembershipsForUser - use UserGroupManager::getUserGroupMemberships
	- ::getMembership - use UserGroupManager::getUserGroupMemberships
	* The public static callback function SpecialBlock::validateTargetField has been
	removed. This method was for internal use only, and appears unused outside of
	MediaWiki core.
	* The public static callback function SpecialUploadStash::tryClearStashedUploads
	has been removed. This method was for internal use only, and appears unused
	outside of MediaWiki core.
	* SpecialComparePages::showDiff() ::revOrTitle(), ::checkExistingTitle(), and
	::checkExistingRevision() were marked as @internal to allow for breaking
	changes. They are no longer safe to call. The methods were unused outside of
	MediaWiki core.
	* Each special page within core now uses service injection via it constructor.
	When extending these special pages, a call to the grandparent constructor
	(`SpecialPage::__construct()`) in the sub-class would now break the derived
	special page, as the fallback code in the parent constructor cannot set the
	services as needed. Be sure to call the parent constructor when extending
	core special pages. Extending core's special pages is not part of the stable
	interface, and should generally be avoided.
	* Language::getExtraUserToggles and ::viewPrevNext, deprecated in 1.34, have
	been removed.
	* StreamFile::send404Message and ::parseRange, deprecated in 1.34, have been
	removed.
	* SVGMetadataExtractor class, deprecated in 1.34, has been removed.
	* ProcessCacheLRU class, deprecated in 1.32, has been removed.
	* wfForeignMemcKey(), deprecated in 1.35, has been removed.
	* LoadBalancer::safeWaitForMasterPos(), deprecated in 1.34, has been removed.
	* JobQueue::factory() now requires its `idGenerator` option. The optional
	nature of this option was deprecated in 1.35.
	* ApiFeedRecentChanges::getFeedObject has been changed to private, and appears
	unused outside of MediaWiki core.
	* Skin::subPageSubtitle() has been changed to private method. Callers should
	use Skin::prepareSubtitle().
	* RevisionDeleter::checkRevisionExistence was removed without deprecation.
	It had no known callers.
	* wfForeignMemcKey() and wfMemcKey(), deprecated in 1.35, have been removed.
	* MediaWiki now also requires the php-intl extension.
	* BotPassword::save() now returns a Status object for the result rather than
	a bool.
	* The methods in CoreTagHooks have been marked @internal and type hints have
	been added. The methods appeared to be unused outside of MediaWiki core.
	* SquidPurgeClient and SquidPurgeClientPool, deprecated since 1.35, have been
	removed.
	* Several methods on WikiPage will now throw an exception when called on a
	WikiPage instance that where constructed on a title that does not refer to a
	proper page (but rather a special page or interwiki link). The behavior was
	previously undefined and could in some cases lead to data corruption. Affected
	methods are: getId(), insertOn(), newPageUpdater(), doUpdateRestrictions(),
	doDeleteArticleReal(), doRollback(), and doEditContent().
	* The ParserTestRunner no longer invokes the ParserTestTables hook. Instead, it
	clones all database tables before running tests, like MediaWikiIntegrationTest
	does. If an extension was mis-using the hook to exclude tables from the
	clone, that will no longer occur, and tests may fail.
	* The following classes, which were only loaded for tests and had no uses found
	in public MediaWiki-related git, were removed:
	- MockWebRequest
	- UserWrapper
	* Passing Title as a second parameter to RevisionStore::getPreviousRevision and
	getNextRevision, hard deprecated since 1.31, was prohibited.
	* (T275619) Maintenance::hasOption and Maintenance::getOption now behave as
	documented and are not altered by previous calls to these methods.
	* The internal class FirejailCommand was removed.
	* Command::execute() now returns a Shellbox\Command\UnboxedResult instead of a
	MediaWiki\Shell\Result. Any type hints should be updated.

	and NamespaceInfo services, deprecated in 1.34, was removed. Note that the
	MediaWikiTitleCodec class is not @newable or @stable to create, and should
	be retrieved from MediaWikiServices instead.
	* The $wgContLang variable, deprecated in 1.32, was removed. You can instead use
	MediaWikiServices::getInstance()->getContentLanguage().
	* User::clearAllNotifications(), hard deprecated in 1.35, was removed. Use

	=== Deprecations in 1.36 ===
	* (T278026) The DB_MASTER constant has been deprecated in favour of DB_PRIMARY.
	* (T245963) User::getGrantName() is now hard deprecated and will be removed in
	a subsequent release. Use MWGrants::grantName() instead.
	* wfIncrStats() is now deprecated. Use MediaWikiServices::getInstance()
	->getStatsdDataFactory()->updateCount() instead.
	* WikiPage::doEditContent() is now deprecated. Use
	WikiPage::doUserEditContent() instead. Note that doEditContent() was also
	deprecated in 1.32 for unrelated reasons and doUserEditContent() is
	deprecated for other reasons, however, using doUserEditContent() is
	recommended over using doEditContent().
	* WikiPage::doUserEditContent() is now deprecated. Use
	PageUpdater::saveRevision instead. Note that the new method expects callers
	to take care of checking EDIT_MINOR against the minoredit right, and to apply
	the autopatrol right as appropriate.
	* LocalFile::recordUpload2, soft deprecated in 1.35, now emits deprecation
	warnings. Use ::recordUpload3 instead.
	* Constructing a new instance of the ParserOptions class without providing
	a User object, which falls back to the global $wgUser, is now deprecated.
	* The User class, which was marked as @newable in 1.35, is no longer newable,
	meaning that it is no longer safe to manually call the constructor via
	`new User`. Instead, use the UserFactory service. Additionally, the
	following static constructor methods were deprecated in favor of using the
	UserFactory service:
	- User::newFromName

	* ParserOptions::setTidy() has been deprecated. It has had no effect since
	1.35.
	* Sanitizer::escapeIdReferenceList() has been deprecated; it will eventually
	be made private to the class, as it appears to have no uses outside the
	Sanitizer class.
	* Sanitizer::hackDocType() is deprecated; it will eventually be made private.
	* Skin::getIndicatorsHTML() is deprecated. The functionality can be retained
	by reimplementing the method using the raw indicators data from
	OutputPage::getIndicators.
	* Skin::makeVariablesScript() has been deprecated. Use
	ResourceLoader::makeInlineScript() instead.
	* SpecialPageFactory::getRestrictedPages() has been deprecated.
	Use SpecialPageFactory::getUsablePages() instead.
	* Title::nameOf() is deprecated; use Title::newFromID()->getPrefixedDBkey()
	instead.
	* DatabaseBlock::insert, DatabaseBlock::update, DatabaseBlock::purgeExpired and
	DatabaseBlock::delete are deprecated. Use DatabaseBlockStore::insertBlock,
	DatabaseBlockStore::updateBlock, DatabaseBlockStore::purgeExpiredBlocks and
	DatabaseBlockStore::deleteBlock instead.
	* SpecialBlock::getTargetAndType and AbstractBlock::parseTarget are deprecated.
	Call BlockUtils::parseBlockTarget instead.
	* SpecialUnblock::processUnblock was deprecated - use UnblockUserFactory
	service instead.
	* Deprecated MediaWikiIntegrationtestCase::removeTemporaryHook() in favor of
	MediaWikiIntegrationtestCase::clearHook().
	* Skin::getSearchLink(), also exposed as 'searchaction' option in SkinTemplate,
	has been deprecated. Use Title or SpecialPage methods directly.
	* Skin::getAllowedSkins and ::getSkinNames have been deprecated. Use their
	respective equivalents in SkinFactory instead.
	* The RollbackComplete hook has been deprecated, use the PageSaveComplete hook
	instead.
	* Skin::makeUrl() has been deprecated. Title methods should be used instead.
	* Skin::privacyLink(), Skin::disclaimerLink() and Skin::aboutLink() have been
	deprecated. Please use Skin::footerLink() instead.
	* Skin::getLogo() has been deprecated. Use ResourceLoaderSkinModule instead.
	* The module `mediawiki.toc.styles` has been replaced by
	ResourceLoaderSkinModule. If you are having problems styling table of contents
	ensure you have an updated skin.
	* Skin::mainPageLink() has been deprecated. Use LinkRenderer service instead.
	* BaseTemplate::getToolbox() method has been hard deprecated. The toolbox data
	is now available in a sidebar data array which you can get from any class
	that's extending QuickTemplate class.
	* Constructing a DefaultPreferencesFactory, LinkHolderArray or PasswordReset
	without a $hookContainer parameter is deprecated.

	* ParserCache::getKey has been deprecated. Use ParserCache::getMetadata and
	ParserCache::makeParserOutputKey instead.
	* The PHPUnit4And6Compat class, used to provide compatibility with PHPUnit 4,
	was removed. MediaWiki support for PHPUnit 4 ended with the removal of HHVM
	support.
	* The PHPUnit6And8Compat class, used to provide compatibility with PHPUnit 6,
	was removed without deprecation. This class was introduced during the
	upgrade to PHPUnit 8, but never used.
	* MediaWikiIntegrationTestCase::assertType, hard-deprecated in 1.35 due to
	incompatibility with PHPUnit 8, was removed.
	* ParserCache::getETag has been deprecated, instead build suitable etag
	explicitly.
	* The following functions from the Language class have been hard deprecated
	and will be removed in a subsequent release:
	- findVariantLink

	- updateConversionTable
	- commafy
	* The following functions from the Title class have been hard deprecated:
	- getPreviousRevisionID
	- getNextRevisionID
	- getEarliestRevTime
	* The following functions from the User class have been hard deprecated:

	* Html::infoBox() has been deprecated. There's no replacement.
	* Message::toString() without a $format parameter, soft-deprecated since 1.28,
	was hard-deprecated. Use explicit formatting methods instead, such as
	Message::text() and Message::escaped().
	* BagOStuff::makeKeyInternal() usage outside of BagOStuff has been deprecated.
	* BagOStuff::setDebug() is deprecated and calls to it are ignored. Debug logs
	are now unconditionally enabled.
	* The following global functions have been hard deprecated:
	- wfAppendToArrayIfNotDefault
	- wfAcceptToPrefs
	- wfClearOutputBuffers
	- wfConfiguredReadOnlyReason
	- wfDebugMem
	- wfGetPrecompiledData
	- wfNegotiateType
	* BeforeParserFetchTemplateAndtitleHook has been deprecated; replace
	with the new BeforeParserFetchTemplateRevisionRecord hook. (The
	similar ParserFetchTemplateHook was deprecated in 1.35; the new hook
	replaces both.)
	* The InterwikiLoadPrefix hook has been deprecated; it is not compatible
	with future wikitext parsers (which need to enumerate all interwiki
	prefixes). In test cases please use $wgInterwikiCache instead.
	* WikiPage instances should no longer be constructed for titles that do not
	represent editable pages (e.g. special pages). WikiPages were always
	documented to represent "MediaWiki article and history".
	* Skin::getSkinStylePath() has been deprecated. Please replace usages with
	the direct path to the resources.
	* The second argument of EnhancedChangesList::getDiffHistLinks, $query, has
	been deprecated.
	* The ParserTestTables hook has been deprecated; it is no longer necessary
	after a ParserTestRunner refactoring.
	* The following classes have been hard deprecated: CachedAction,
	SpecialCachedPage, CacheHelper, ICacheHelper. They were unused in MediaWiki
	ecosystem, so no replacement was provided.
	* The ProtectionForm::buildForm hook has been deprecated. Please use the
	ProtectionFormAddFormFields hook instead.
	* RevisionStore::newMutableRevisionFromArray has been hard deprecated. Instead,
	MutableRevisionRecord should be constructed directly via constructor.
	* UserIdentity::getActorId() is deprecated. The actor ID should not be exposed
	to application logic. Storage layer code should use the ActorNormalization
	service for normalizing and denormalizing user names.
	* Constructing a UserIdentityValue with an actor ID as the third parameter is
	deprecated. The parameter should be omitted. Storage layer code should use
	the ActorNormalization service for normalizing and denormalizing user names.
	* Command::cgroup() is deprecated and no longer functional. $wgShellCgroup is
	now implemented as an Executor option.
	* Command::restrict() is deprecated. Instead use the new separate accessors.
	* MWTidy::tidy() is deprecated. Use MediaWikiServices::getTidy()-tidy() instead.
	* TidyDriverBase::supportsValidate() is deprecated; it has always returned
	false since 1.33.
	* WatchedItem::getUser hard-deprecated in favor of ::getUserIdentity.
	* WatchedItemStoreInterface::enqueueWatchlistExpiryJob was hard deprecated in
	favor of the new method maybeEnqueueWatchlistExpiryJob that takes care of
	relevant configuration checks.
	* LogEntry::getPerformer() and its implementations have been hard-deprecated, in
	favor of ::getPerformerIdentity().
	* AuthManager::singleton(), deprecated in 1.35, is hard deprecated. Use
	MediaWikiServices::getAuthManager() instead.
	* User::clearNotification(), deprecated in 1.35, is hard deprecated. Use
	WatchlistManager::clearTitleUserNotification() instead.
	* Passing string to DatabaseBlock::setBlocker was deprecated. Only UserIdentity
	is now allowed.
	* DatabaseBlock constructor 'byText' option was deprecated in favour of 'by'
	option, which now accepts UserIdentity. Passing user ID is deprecated.
	* Parser::getUser was deprecated. Use Parser::getUserIdentity instead.
	* DatabaseBlock::isWhitelistedFromAutoblocks was deprecated. Use
	DatabaseBlock::isExemptedFromAutoblocks instead.
	* User::isIPRange(), deprecated in 1.35, is hard deprecated.
	Use the UserNameUtils service or IPUtils directly.
	* BaseTemplate::getFooterIcons(), deprecated in 1.35, is hard deprecated. Read
	footer icons from template data requested via $this->get('footericons').
	* `box-shadow()` LESS mixin from mediawiki.mixins is deprecated due to updated
	basic browser support. Use unprefixed property `box-shadow:` instead.
	* MergeHistory::checkPermissions was deprecated. Use ::probablyCanMerge or
	::authorizeMerge instead.
	* User::isValidUserName(), deprecated in 1.35, is hard deprecated.
	Use the UserNameUtils service instead.
	* The TitleArrayFromResult hook has been deprecated.
	* The EditPageBeforeEditToolbar hook has been deprecated; it has become
	defunct after the classic edit toolbar was removed. Use one of the many
	other EditPage hooks instead.
	* Deprecated the class name MediaWiki\User\WatchlistNotificationManager; use
	MediaWiki\Watchlist\WatchlistManager instead. Deprecated the method
	MediaWikiServices->getWatchlistNotificationManager(); use
	MediaWikiServices->getWatchlistManager() instead.
	* The "ArticleEditUpdatesDeleteFromRecentchanges" hook, deprecated in 1.35, has
	been removed. Other hooks like "RecentChange_save" can be used instead.

	=== Other changes in 1.36 ===
	* The 'tidy' key in ParserOptions (used in the parser cache) has been removed.
	It has had no effect since 1.35.
	* A future release of MediaWiki will make `{{=}}` a built-in parser function,
	for use when automatically escaping the `=` character in template arguments.
	A tracking category and parser warning have been added to this release when
	`{{=}}` is used and it expands to something other than `=`.
	* The implementation of TestFileReader::read has been changed to use Parsoid's
	parser test file parser. This should be compatible with existing code, but it
	only supports version 2 of the test file specification and may be more strict
	when parsing invalid input, including duplicate tests.
	* BeforeParserFetchTemplateRevisionRecord, a new hook, unifies and replaces the
	old BeforeParserFetchTemplateAndtitleHook and ParserFetchTemplateHook.
	* The SkinLessImportPaths attribute was added, allowing skins to add a directory
	to the import path for LESS stylesheets. Skins can use this to provide a
	custom version of mediawiki.skin.variables.less, setting skin-specific values
	for certain LESS variables.
	* The interaction between ContentHandler::getParserOutputForIndexing() and
	ContentHandler::getDataForSearchIndex() has been clarified (the latter should
	only be called with the result of the former). Extensions may override
	getParserOutputForIndexing() to skip generating HTML, which may improve
	indexing performance. (The default implementation still generates HTML, and
	getDataForSearchIndex() implementations can still rely on it if they do not
	over-ride getParserOutputForIndexing().)
	* Article::fetchContentObject, ::mContentObject, ::mContentLoaded,
	::mRevIdFetched, all deprecated since 1.32, were removed.
	* Article::mParserOptions and ::setParserOptions were removed.
	* Article and ImagePage::getEmptyPageParserOutput, unused, were removed.
	* ParserCache's default serialization format was changed from PHP serialization
	to JSON serialization. In case some installed extension do not support JSON
	yet, $wgParserCacheUseJson can be used to revert back to PHP serialization.
	* PermissionManager::groupHasPermission, ::getGroupPermissions and
	::getGroupsWithPermission were deprecated, use GroupPermissionsLookup
	service instead.
	* WatchedItemStoreInterface now accepts PageIdentity where it accepted
	LinkTarget, calling with LinkTarget was deprecated.
	* 'movable' attribute has been added to the 'namespaces' property of
	extension.json schema. Extensions that define namespaces can set it to
	`false` to disallow moving pages in the specified namespace. Extensions
	should either use this or NamespaceIsMovableHook, but not both. The hook
	overrides the attribute.

	== Compatibility ==

	MediaWiki 1.36 requires PHP 7.3.19 or later and the following PHP extensions:

	* ctype
	* dom
	* fileinfo
	* iconv
	* intl
	* json
	* mbstring
	* xml

	MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
	but support for them is somewhat less mature.

	The supported versions are:

	* MySQL 5.5.8 or later
	* PostgreSQL 9.4 or later
	* SQLite 3.8.0 or later

	== Online documentation ==
	Documentation for both end-users and site administrators is available on
	MediaWiki.org, and is covered under the GNU Free Documentation License (except
	for pages that explicitly state that their contents are in the public domain):

	https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation

	== Mailing list ==
	A mailing list is available for MediaWiki user support and discussion:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

	A low-traffic announcements-only list is also available:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

	It's highly recommended that you sign up for one of these lists if you're
	going to run a public MediaWiki, so you can be notified of security fixes.

	== IRC help ==
	There's usually someone online in #mediawiki on irc.libera.chat.

	= MediaWiki 1.35 =

	MediaWiki 1.35 should mostly work on PHP 8.0/8.1, however it is not
	currently actively supported. Testing (on a development wiki!) is
	appreciated, and bugs with PHP 8.0/8.1 on MediaWiki 1.35 will be accepted.

	It is anticipated that in a later MediaWiki 1.35 point release, we can
	declare 1.35 as supporting PHP 8.0/8.1.

	== MediaWiki 1.35.0-rc.0 ==

	== Upgrading notes for 1.35 ==
	1.35 requires PHP 7.3.19 or above (up from 7.2.9). (T257879)

	1.35 has several database changes since 1.34, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	Don't forget to always back up your database before upgrading!

	MediaWiki 1.35 is the next LTS after 1.31, and will be supported for around 3
	years.

	MediaWiki has a lot of both soft and hard deprecations, and code removed. As
	always, make sure your versions of extensions match the MediaWiki version,
	and updates may be required to any custom extensions.

	See the file UPGRADE for more detailed upgrade instructions, including
	important information when upgrading from versions prior to 1.11.

	Some specific notes for MediaWiki 1.35 upgrades are below:
	* (T259685) When using SQLite as the database backend for MediaWiki,
	Zeroconf (zero-configuration) VisualEditor/Parsoid only works with
	MediaWiki 1.35.2 and above. It is still recommended to use
	MySQL/MariaDB rather than SQLite when using VisualEditor.

	For notes on 1.34.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.35 ===

	* (T72470) $wgLegacyJavaScriptGlobals is now false by default. This feature
	will be completely removed in a later MediaWiki release.

	==== New configuration ====
	* $wgDiffEngine — This can be used to specify the difference engine to use,
	rather than MediaWiki choosing the first of $wgExternalDiffEngine, wikidiff2,
	or php that is usable.
	* $wgSearchMatchRedirectPreference — This configuration setting controls whether
	users can set a new preference, search-match-redirect, which decides if search
	should redirect them to exact matches is available. By default, this is set to
	false, which maintains the previous behaviour without preference bloat. Change
	your site's default by setting $wgDefaultUserOptions['search-match-redirect'].
	* $wgPoolCounterConf['SpecialContributions'] — Per-user concurrency in the use
	of SpecialContributions can now be limited by setting this appropriately.
	* $wgPasswordPolicy — PasswordCannotBeSubstringInUsername is a new password
	policy check. Similar to the existing PasswordCannotMatchUsername check, this
	check ensures that a user's (case-insensitive) password cannot be a part of
	their username. e.g. password = MyPass, username = ThisUsersPasswordIsMyPass.
	* $wgLogos — This new configuration setting combines the now-deprecated $wgLogo
	and $wgLogoHD settings into a single, associative array. It provides support
	for a new key, 'wordmark', for setting a horizontal wordmark to show next to
	the graphical logo. To do this, set 'wordmark' to an array with 'src' set to
	the path of the wordmark image, and 'width' and 'height' for its dimensions
	in pixels. $wgLogos inherits the existing support provided by its predecessor
	settings: '1x' mapping to the path of the logo as a 135x135px raster image
	(equivalent to $wgLogo), and '1.5x', '2x', and 'svg' operating as before for
	$wgLogoHD. If $wgLogos is unset, $wgLogo and $wgLogoHD values are read for
	temporary backwards compatibility. (T232140)
	* $wgWatchlistExpiry — (EXPERIMENTAL) This enables the new watchlist expiry
	feature. The database table (watchlist_expiry) for this is created regardless
	of this setting, but all other aspects of the expiry feature are controlled
	by it. Enabling in production is discouraged for the time being. A future
	MediaWiki 1.35 release will advertise this feature once it is stable.
	* $wgWatchlistPurgeRate — This sets the chance of expired watchlist items being
	purged on each page edit. Only has effect if $wgWatchlistExpiry is true.
	* $wgWatchlistExpiryMaxDuration — This is the maximum definite relative duration
	for watchlist expiries. Only has effect if $wgWatchlistExpiry is true.
	* $wgImgAuthPath – This can be used to override the path prefix used when
	handling img_auth.php requests. (T235357)
	* $wgAllowedCorsHeaders — This is a list of headers which can be used in a
	cross-site API request.
	* $wgHTTPMaxTimeout and $wgHTTPMaxConnectTimeout — These allow site
	administrators to limit the timeouts used by the HTTP client libraries.
	This only affects callers using HttpRequestFactory and the deprecated
	wrappers in the Http class.
	* $wgCdnMaxageStale — This controls the Cache-Control s-maxage header for page
	views when PoolCounter lock contention indicates that a stale cache entry
	should be sent.
	* $wgForceHTTPS — This makes the HTTP to HTTPS redirect be unconditional and
	suppresses various hacks needed to support mixed HTTP/HTTPS wikis. We
	recommend this be set to true on pure HTTPS wikis.
	* $wgCookieSameSite — This setting allows login cookies to be sent with
	SameSite=None. This is required for cross-site CentralAuth auto-login after
	Chrome 84.
	* $wgUseSameSiteLegacyCookies — This adds a compatibility hack to
	SameSite=None cookies for browsers which implemented an incompatible draft
	version of the specification.

	==== Changed configuration ====
	* $wgResourceLoaderMaxage (T235314) — This configuration array controls the
	max-age for HTTP caching through the Cache-Control header. It has uses the
	"versioned" key for urls that do have a version parameter, and the
	"unversioned" key for urls without a version parameter. The sub keys for
	"client" and "server" are no longer supported in MediaWiki 1.35.
	* $wgEnableOpenSearchSuggest — This boolean variable is deprecated and no longer
	used. The OpenSearch API is now always enabled.
	* $wgAuthManagerConfig and $wgAuthManagerAutoConfig — These can now use the
	'services' option in provider specifications.
	* $wgVirtualRestConfig['modules']['parsoid'] —
	- The defaults have been updated. If you were relying on the default values,
	you may need to update your configuration.
	- The 'URL' parameter, previously allowed for backwards-compatibility, has
	been deprecated. Use 'url' instead.
	* $wgXmlDumpSchemaVersion — Default is now set to XML_DUMP_SCHEMA_VERSION_11, so
	dumps use the new dump format by default. Consumers of XML dumps should not
	be affected if they ignore any unknown tags they encounter. Also, the format
	is effectively unchanged for revisions that only contain the main slot. The
	--schema-version option can be used with the dumpBackup.php script to set the
	dump format. (T238921)
	* $wgParserConf — This configuration is now deprecated. It has been
	effectively constant since 2008, and is ignored by core code.
	Configure the ParserFactory service in order to customize the Parser used.
	* $wgAutoloadAttemptLowercase — This has been deprecated, and the default value
	changed to false.
	* $wgAllowImageMoving — This configuration setting is now deprecated. Instead,
	use $wgGroupPermissions; e.g., to revoke sysops' ability to move images use
	$wgGroupPermissions['sysop']['movefile'] = false.
	* $wgAllowImageTag — This configuration is now deprecated; future parsers will
	not support direct use of the HTML <img> tag in wikitext.
	* $wgUseTwoButtonsSearchForm — This has been deprecated. If you maintain a skin
	that relies on this and wishes to let system administrators change it, you
	should convert it to a config variable specific to your skin. If you're using
	it to configure your wiki, you should check individual skins to see whether
	they have local skin config for the feature and use that.
	* $wgPasswordPolicy — The deprecated policy 'PasswordCannotBePopular' has been
	removed. Use PasswordNotInCommonList instead which covers many more passwords.
	* Backwards compatibility for using an associative array
	(e.g. [ '127.0.0.1' => 'bad-ip' ]) for $wgProxyList has been removed. This
	was deprecated since 1.30. Please convert these arrays to indexed/sequential
	ones (e.g. [ '127.0.0.1' ]).
	* $wgShellRestrictionMethod — This now defaults to 'autodetect', which will
	enable sandboxing for shell commands using firejail, if it's installed. To
	disable restrictions, set it to false.
	* $wgLegacyJavaScriptGlobals – This deprecated setting now default to false,
	instead of true, ahead of its planned removal.

	==== Removed configuration ====
	* $wgSysopEmailBans — This setting, deprecated in 1.34, was removed. To let
	sysops block email access, use $wgGroupPermissions['sysop']['blockemail'].
	* $wgDBWindowsAuthentication — This setting had no effect anymore after support
	for SQL Server was removed in 1.34. (T230418)
	* $wgProfileOnly — This setting, deprecated in 1.23, was removed. The profiler
	output should instead be configured via $wgProfiler['output'].
	* $wgProfileLimit — This setting, deprecated in 1.25, was removed.
	Set $wgProfiler['threshold'] instead.
	* $wgDebugTimestamps — This setting was removed. It affected the text output
	produced via $wgDebugComments, if enabled.
	* $wgSkipSkin — This setting, deprecated in 1.23, was removed. To disable a
	skin from being shown, use $wgSkipSkins.
	* $wgUseSquid, $wgSquidServers, $wgSquidServersNoPurge, and $wgSquidMaxage —
	These, deprecated in 1.34, have been removed. Use $wgUseCdn, $wgCdnServers,
	$wgCdnServersNoPurge, or $wgCdnMaxAge instead.
	* $wgDisableCounters — This, deprecated in 1.25, was removed. The feature that
	it controlled was already removed in 1.26, but the variable remained existent
	with a value of `false` for backward-compatibility.
	* $wgMaxGeneratedPPNodeCount — This setting was removed. It only affected
	Preprocessor_DOM, which was deprecated in 1.34 and removed in this release.
	* $wgFixArabicUnicode and $wgFixMalayalamUnicode — These, deprecated in 1.33,
	were removed. The fixes are now always enabled for their respective languages.
	* $wgAllowTitlesInSVG — This, unused and deprecated since 1.34, was removed.
	* $wgEnablePartialBlocks — This setting, deprecated when it was added in 1.33,
	was removed. Partial blocks are now always enabled.
	* $wgLocalInterwiki — This setting, deprecated in 1.23, has been removed.
	* $wgContentHandlerUseDB — This setting, deprecated in 1.34, has been removed.
	* $wgMultiContentRevisionSchemaMigrationStage — This setting must no longer
	be set locally. If the migration stage was set to anything other than
	SCHEMA_COMPAT_NEW locally, update.php must be run after removing the setting.
	Usage of the setting in code is deprecated. The setting will be removed
	completely in 1.36.
	* $wgEnableRestAPI — This setting is no longer obeyed by MediaWiki core, and
	should not be set set locally. Usage of the setting in code is deprecated; it
	is now set true by default. The setting will be removed completely in 1.36.
	* $wgObjectCaches — The 'slaveOnly' option for SqlBagOStuff, deprecated in 1.34,
	was removed. Use 'replicaOnly' instead.

	=== New user-facing features in 1.35 ===
	* (T204618) Whitelisted the aria-hidden HTML attribute for all elements in
	wikitext.
	* (T13456) Special:EditPage, Special:PageHistory, Special:PageInfo, and
	Special:Purge have been created as shortcuts for each action.
	Special:EditPage/Foo redirects to title=foo&action=edit, with PageHistory,
	PageInfo, and Purge corresponding to action= history, info, and purge
	respectively. When linked to, its subpage is used as the target. Otherwise,
	it displays a basic interface to allow the end user to specify the target
	manually.
	* (T139221) The generated table of contents is now a navigation landmark role
	for assistive technologies.
	* (T245931) interwiki map API doesn't report foreign language if
	$wgInterwikiMagic=false
	* The form at ?action=watch has a new dropdown list to support expiry dates for
	watchlist items (if $wgWatchlistExpiry is true).

	=== New developer features in 1.35 ===
	* A Docker based local development develpoment environment configuration is
	included (T238224) and DEVELOPERS.md has been added with usage documentation
	and links to further help.
	* If CSP is enabled, extensions can now add additional sources using the
	ContentSecurityPolicy::addDefaultSource, ::addStyleSrc and ::addScriptSrc
	methods (e.g. $context->getOutput()->getCSP()->addDefaultSrc( 'example.com' ))
	* Extensions can now specify classes and namespaces to be autoloaded by the
	test autoloader, by setting the "TestAutoloadNamespaces" and
	"TestAutoloadClasses" properties in extension.json. (T196090)
	* (T250977) extension.json now allows "SearchMappings" which maps the canonical
	name of the search engine (used in wgSearchType and wgSearchTypeAlternatives)
	to a specification using the ObjectFactory specification. This allows
	extensions to register Search Engines using namespaced classes.
	* Added getters for OutputPage's robot, index and follow policies;
	getRobotPolicy() returns the entire policy as a string in the form
	<index policy>,<follow policy> while getIndexPolicy() and getFollowPolicy()
	return their respective policies as a string.
	* The ResourceLoaderSiteModulePages and ResourceLoaderSiteStylesModulePages
	hooks were added to allow changing which wiki pages these modules contain.
	* The SkinFactory now allows skins to be specified as an ObjectFactory spec,
	allowing the construction of skins with services injected.
	* ContentHandlerFactory for most ContentHandler static methods. It has been
	added to the constructors for many classes to improve SOLID / GRASP.
	* FileDeleteForm's constructor now accepts a user as the second parameter.
	Support for not passing a user has also been hard-deprecated and will be
	removed in 1.36.
	* The ParserPreSaveTransformComplete hook was added.
	* The ParserBeforePreprocess hook was added.
	* The ResourceLoaderSkinModule class now has a "legacy" feature that loads
	the stylesheets previously part of the "mediawiki.legacy.shared" and
	"mediawiki.legacy.commonPrint" module.
	Those modules are now deprecated and no longer loaded by skins.
	For skins needing to retain these styles, you will need to load these
	styles via a module using the ResourceLoaderSkinModule class.
	See Vector and Monobook for examples.
	* ParserOutput now has methods addExtraCSPStyleSrc, addExtraCSPDefaultSrc
	addExtraCSPScriptSrc for parser tags/functions to be able to add sources
	to the Content Security Policy.
	* The HtmlCacheUpdater service was added to unify the logic of purging CDN cache
	and HTML file cache to simplify callers and make them more consistent.
	* The MultiHttpClient code will fallover to non-curl if curl_multi* is blocked.
	* Preferences which use HTMLTitlesMultiselectField can make use of
	MultiTitleFilter class for saving title text to/from article IDs in user
	preferences.
	* OutputPage::addHtmlClasses() was added to allow injecting CSS classes on
	to the <html> element on page load.
	* The SkinAddFooterLinks hook is added to allow extensions to add items to skin
	footers. Previously this had to be done via SkinTemplateOutputPageBeforeExec.
	Doing so using that hook is now hard deprecated.
	* A new BlockPermissionChecker service was introduced for checking
	block-related permissions.
	* The support of 'database' type of extensions has been added to allow 3d party
	databases like Percona be used as storage. See T226857, T253248.
	* Three new return parameters have been added to the
	EditPageGetCheckboxesDefinition hook. Handlers of this hook are no longer
	restricted to defining checkboxes. See the documentation of
	EditPage::getCheckboxesDefinition() for more details.
	* New flag File::RENDER_TMP was added in order to allow
	File::generateAndSaveThumb and File::trasform to render a thumbnail without
	saving it to the storage.

	* phpunit/php-invoker (dev-only).
	Removing this unbreaks development on Windows systems, in exchange for losing
	time limits in running unit tests.
	* The jquery.getAttrs module was removed.

	=== Action API changes in 1.35 ===
	* The 'suggest' parameter of action=opensearch has been deprecated.
	The API behaves the same with and without this parameter.
	It was previously used by $wgEnableOpenSearchSuggest to partially
	disable the API if set to false. Specifically, it would deny internal
	frontend requests carrying this parameter, whilst accepting other requests.
	* Integer-type parameters are now validated for syntax rather than being
	interpreted in surprising ways. For example, the following will now return a
	badinteger error:
	- "1.9" (formerly interpreted as "1")
	- " 1" (formerly interpreted as "1")
	- "1e1" (formerly interpreted as "1" or "10", depending on the PHP version)
	- "1foobar" (formerly interpreted as "1")
	- "foobar" (formerly intepreted as "0")
	parameters. Ranges should be assumed to be enforced.
	* Many user-type parameters now accept a user ID, formatted like "#12345".
	* The 'assert' parameter used by all API modules now supports the value 'anon'.
	When specified, the API will return the 'assertanonfailed' error if the user
	is logged in.
	* action=edit now supports the 'baserevid' parameter for edit conflict
	detection, as an alternative to 'basetimestamp'. Note that self-conflicts
	will continue to be ignored if 'basetimestamp' is set, but not if only
	'baserevid' is set.
	* A new module was added to change the content model of existing pages.
	Use action=changecontentmodel. Unlike Special:ChangeContentModel, the api
	module does not work for pages that do not already exist.
	* If $wgWatchlistExpiry is true, the following API changes are made:
	- action=watch accepts a new 'expiry' parameter analagous to the expiry
	accepted by action=userrights, action=block, etc., except it must be no
	greater than $wgWatchlistExpiryMaxDuration, or an infinity value.
	- action=query&list=watchlistraw returns pages' watchlist expiry dates.
	* (T249526) action=login will now return Failed rather than NeedToken on
	session loss.

	=== Action API internal changes in 1.35 ===
	* The Action API now uses the Wikimedia\ParamValidator library for parameter
	validation, which brings some new features and changes. For the most part
	existing module code should work as it did before, but see subsequent notes
	for changes.
	- The values for all ApiBase PARAM_* constants have changed. Code should have
	been using the constants rather than hard-coding the values.
	- Several ApiBase PARAM_* constants have been deprecated, see the in-class
	documentation for details. Use the equivalent ParamValidator constants
	instead.
	- The value returned for 'upload'-type parameters has changed from
	WebRequestUpload to Psr\Http\Message\UploadedFileInterface.
	* Validation of 'user'-type parameters is more flexible. PARAM constants exist
	to specify the type of "user" allowed and to request UserIdentity objects
	rather than name strings. The default is to accept all types (name, IP,
	range, and interwiki) that were formerly accepted.
	* Maximum limits are no longer ignored in "internal mode".
	* The $paramName to ApiBase::handleParamNormalization() should now include the
	prefix.
	* (T245931) meta=siteinfo&siprop=interwikimap no longer reports language or
	extralanglink when $wgInterwikiMagic is false.

	=== Languages updated in 1.35 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* The default targets for the ISBN search from Special:BookSources in English
	have been updated for better international suppport. They will now be
	BetterWorldBooks.com, OpenLibrary.org and Worldcat.org.
	* (T237672) Changed the Moroccan Arabic language (ary) to the Arabic script.
	* (T201269) Added language support for Amis (ami).
	* (T248299) Added language support for Inari Sami (smn).
	* (T251369) Added language support for Ladin (lld).
	* (T251369) Added language support for Seediq (trv), also known as Taroko.
	* (T254854) Added language support for Southern Altay (alt).

	=== Breaking changes in 1.35 ===
	* MediaWiki no longer supports PHP 7.2; use PHP 7.3.19+ (T228346, T257879).
	* ResourceLoader::getLessVars(), deprecated in 1.32, was removed.
	Use ResourceLoaderModule::getLessVars() instead.

	* The easy-deflate.deflate module was removed. Use the mediawiki.deflate
	module instead.

	Use "user.options" instead.
	* (T251855) The mw.Map#exists method in JavaScript no longer supports checking
	multiple keys. This affects mw.config.exists() and mw.user.tokens.exists().
	* The internal variable $constructorOptions for the Parser & SpecialPageFactory,
	exposed only for integration purposes, are now each replaced by a const called
	CONSTRUCTOR_OPTIONS. This was a breaking change made without deprecation.
	* ObjectCache::getWANInstance, deprecated in 1.34, was removed.
	Use MediaWikiServices::getMainWANObjectCache instead.
	* ObjectCache::newWANCacheFromParams, deprecated in 1.34, was removed.

	* AbstractBlock::mReason, deprecated in 1.34, is no longer public.
	* The GetBlockedStatus and UserIsHidden, deprecated in 1.34, has been removed.
	Instead, use the GetUserBlock hook.
	* As part of work to replace the Parser, a large number of breaking changes have
	been made, principally in related methods and properties being removed or made
	private:
	- disableCache(), deprecated in 1.28.
	- serializeHalfParsedText() and the helpers unserializeHalfParsedText(),
	isValidHalfParsedText(), and StripState::getSubState() and
	StripState::merge(), all deprecated in 1.31. The helper functions
	LinkHolderArray::mergeForeign() and LinkHolderArray::getSubArray()
	were also removed.
	- getConverterLanguage(), deprecated in 1.32. Use getTargetLanguage() instead.

	- Parser::getTitle() will now throw a TypeError if $mTitle is uninitialized.
	This use pattern was deprecated in 1.34.
	- ContentHandler::makeParserOptions(), deprecated in 1.32, was removed. Use
	WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
	- The ParserAfterUnstrip hook, believed to be unused, was removed without
	deprecation.
	- Preprocessor_DOM and related classes, deprecated in 1.34, have been removed.
	Consequently, the related ParserOptions::getMaxGeneratedPPNodeCount() and
	::setMaxGeneratedPPNodeCount() have been removed without deprecation.
	- The support for the old signature for ParserFactory::__construct, which was
	deprecated in 1.34, has been removed.
	- Parser::getDefaultPreprocessorClass(), deprecated in 1.34, has been removed.
	* MediaWikiTestCase::prepareServices(), deprecated in 1.32, has been removed
	* The method ContentHandler::getSlotDiffRendererInternal is replaced with

	call parent::getSlotDiffRendererInternal (no instances of which are known).
	* TextContent::getHighlightHtml, deprecated since 1.24, has been removed. Use
	TextContent::getHtml instead.
	* ExtensionRegistry::load(), deprecated in 1.34, was removed. Instead, use

	wikimedia/cdb library instead.
	* User::addNewUserLogEntryAutoCreate, deprecated in 1.27, was removed.
	* FileBasedSiteLookup class, deprecated in 1.33, was removed.
	* The wfGlobalCacheKey global function, deprecated in 1.30, was removed.
	* The APCBagOStuff class was removed. MediaWiki requires PHP 7.2+ (support
	for HHVM was dropped) and these versions of PHP only support apcu. The default
	"apc" entry in $wgObjectCaches now refers to APCUBagOStuff.
	* Database::bufferResults(), deprecated in 1.34, has been removed.
	* CannotReplaceActiveServiceException, ContainerDisabledException,
	DestructibleService, NoSuchServiceException, SalvageableService,
	ServiceAlreadyDefinedException, ServiceContainer and ServiceDisabledException
	in the global namespace, deprecated in 1.33, were removed. Use the classes in
	the MediaWiki\\Services namespace instead.
	* The following methods in the Interwiki class were removed: ::fetch(),
	::isValidInterwiki(), ::invalidateCache(), and ::getAllPrefixes().
	* The UsersMultiselectWidget config 'allowArbitrary' is now false by default. To
	accept arbitrary entries, pass in true for this config.
	* OutputPage::parse() and OutputPage::parseInline(), deprecated in 1.32, have
	been removed. Use ::parseAsContent() or ::parseAsInterface(), as
	appropriate.
	* WikiPage::selectFields, deprecated in 1.31, was removed. Use ::getQueryInfo.
	* The remaining static methods for MagicWord, deprecated in 1.32, were removed.
	These were MagicWord::get(), ::getSubstIDs(), ::getDoubleUnderscoreArray(),
	::getVariableIDs(), and ::getCacheTTL(). Instead, use MagicWordFactory (via
	MediaWikiServices).
	* ApiBase::checkTitleUserPermissions no longer accepts a User as the third
	parameter. Passing a user was deprecated in 1.33.
	* Sanitizer::setupAttributeWhitelist() and Sanitizer::attributeWhitelist(),
	deprecated in 1.34, have been removed. They should not have been public.
	* Passing a sequential array as the second parameter to

	its introduction in 1.28, has been removed.
	* SpecialRecentChanges::filterByCategories(), deprecated in 1.31, was removed.

	* Title::moveSubpages, deprecated in 1.34, was removed. Use the MovePage class
	and MovePage::moveSubpages instead.

	WikiPage::doEditContent.
	* CommentStore::newKey, deprecated in 1.31, was removed.
	* EditPage::$hookError was changed from public to private.
	* Title::isValidMoveOperation, ::moveTo, and ::isValidMoveTarget, deprecated
	in 1.25, were removed. Use the MovePage class and its methods instead.
	* Title::getUserCaseDBKey(), deprecated in 1.33, was removed. Use ::getDBkey().
	* StringUtils::explodeMarkup() was removed without deprecation.
	* AjaxResponse methods that were unused have been removed without deprecation:
	- checkLastModified
	- loadFromMemcached
	- storeInMemcached
	- setCacheDuration
	- setVary
	* ApiDelete::delete and ::deleteFile, both of which were protected methods,
	have been made private to allow a signature change.
	* HistoryPager::revLink, ::curLink, ::lastLink, and ::diffButtons, which had
	no visibilities defined, have been made private to allow signature changes.
	* SpecialNewpages::revisionFromRcResult, which previously was protected, has
	been made private to allow a signature change.
	* DifferenceEngine::$mOldRev and $mNewRev, deprecated for public access in
	1.32, have been removed.
	* DifferenceEngine::revisionDeleteLink, which was previosuly protected, has
	been made private to allow a signature change.
	* DifferenceEngine::getParserOutput, which is protected, has had a breaking
	signature change: the second parameter must be a RevisionRecord object,
	rather than a Revision object.
	* WikiPage::setLastEdit, which was previously protected, has been made
	private to allow a signature change.
	* Skin::getSkinNameMessages() deprecated in 1.34, has been removed.
	* Skin::escapeSearchLink() deprecated in 1.34, has been removed, use
	Skin::getSearchLink() instead.
	* Skin::shouldPreloadLogo() deprecated in 1.32, has been removed.
	* Revision::loadFromId and RevisionStore::loadRevisionFromId have been
	removed.
	* OutputPage::parserOptions doesn't accept an $options parameter anymore.
	* MessageCache::getParserOptions previously did not have a visibility set.
	It has been made private.
	* SpecialUndelete::showDiff previously did not have a visibilty set. It
	hav been made private to allow a signature change.
	* The Skin no longer loads the "mediawiki.legacy.shared" or
	"mediawiki.legacy.commonPrint" modules. The legacy shared styles must now
	be loaded by the skin explicitly, either inherited via the
	"mediawiki.skinning.*" modules, or by making your skin's main styles
	module use the ResourceLoaderSkinModule class with the "legacy" attribute.
	See Vector and Monobook for examples.
	* Passing an ApiMain to the constructor of ApiResult is no longer supported.
	This was deprecated in 1.25.
	* ResourceLoaderWikiModule::invalidateModuleCache has been declared to
	be @internal as part of a signature change. No known uses exist outside
	of MediaWiki core.
	* The ArticleAfterFetchContentObject hook, deprecated in 1.32, was removed.
	Use ArticleRevisionViewCustom to control output.
	* DatabaseBlock::isValid, deprecated in 1.33, was removed.
	* HTMLUserTextField and HTMLUsersMultiselectField previously implied
	required=true when exists=true. Form fields that use exists=true should also
	set required=true if they are required.
	* In DatabaseUpdater, the following methods are no longer public: dropTable(),
	modifyTable(), modifyField(), runMaintenance(), copyFile(), appendLine().
	In PostgresUpdater, the following methods are no longer public:
	addPgEnumValue(), addPgIndex(), addPgExtIndex(). This change was made without
	deprecation due to immediate danger of data corruption and loss, see T157651.
	Extensions should instead use dropExtensionTable(),
	modifyExtensionExtensionTable(), modifyExtensionField(), addExtensionUpdate().
	The addExtensionUpdate() method can still be used to access any of the
	protected methods on DatabaseUpdater.
	* ResourceLoader no longer provides the (always-true) variables for wgEnableAPI
	and wgEnableWriteAPI; they were deprecated in MediaWiki 1.31 and removed from
	the PHP environment in MediaWiki 1.32.
	* The wfSetupSession global function, deprecated in 1.27, was removed. Use the
	persist() method of the right MediaWiki\Session\SessionManager object instead.
	* The wfIsHHVM global function, deprecated in 1.34, was removed.
	* GenderCache::doTitlesArray no longer accepts string values in its $titles
	array parameter. Use Title objects (or other LinkTarget) instead.
	* Unused CommentStore::MAX_COMMENT_LENGTH has been removed.
	* User::checkTemporaryPassword() and User::checkPassword(), deprecated in 1.27,
	were removed. Use AuthManager instead.
	* All constants and class functions now have explicit visibility modifiers. This
	means, per [[mw:Stable interface policy]], that these should now be considered
	stable. This also helps MW align with PSR 2 and PSR 12. This was done based on
	audits of the corpus of skins and extensions hosted in Gerrit. If you find any
	that you need to be less restrictive (i.e. public or protected), please report
	these so that we can re-evaluate or suggest workarounds.
	* BaseTemplate::msgWiki(), deprecated in 1.33, was removed. Use ->msg() or
	->getMsg() instead.
	* QuickTemplate::msgWiki(), deprecated in 1.33, was removed. Use ->msg()
	instead.
	* WebInstaller::getErrorBox() and ::getWarningBox(), deprecated in 1.34,
	were removed. Use Html::errorBox() or ::warningBox() instead.
	* SpecialVersion::getExtensionCredits() and SpecialVersion::getSkinCredits()
	have become private without deprecation.
	* As part of the migration to a new hook system (T240307), the following classes
	now require an additional HookContainer constructor parameter:
	- AuthManager
	- BadFileLookup
	- BlockManager
	- ClassicInterwikiLookup
	- ContentHandlerFactory
	- ContentSecurityPolicy
	- DefaultOptionsManager
	- DerivedPageDataUpdater
	- FullSearchResultWidget
	- HtmlCacheUpdater
	- LanguageFactory
	- LanguageNameUtils
	- LinkRenderer
	- LinkRendererFactory
	- LocalisationCache
	- MagicWordFactory
	- MessageCache
	- NamespaceInfo
	- PageEditStash
	- PageHandlerFactory
	- PageUpdater
	- ParserFactory
	- PermissionManager
	- RevisionStore
	- RevisionStoreFactory
	- Router
	- SearchEngineConfig
	- SearchEngineFactory
	- SearchFormWidget
	- SearchNearMatcher
	- SessionBackend
	- SpecialPageFactory
	- UserNameUtils
	- UserOptionsManager
	- WatchedItemQueryService
	- WatchedItemStore
	* The following classes now require setHookContainer() to be called after
	construction:
	- AuthenticationProvider
	- ResourceLoaderModule
	- SearchEngine
	* The parameters to ChronologyProtector::getTouched() and
	ILBFactory::getChronologyProtectorTouched() were changed without backwards
	compatibility.
	* The deprecated $blacklist parameter to wfIsBadImage() has been removed.
	* SpecialBlock::checkUnblockSelf no longer accepts an integer representing
	an user ID as part of ongoing refactoring of SpecialBlock class.
	* User::setInternalPassword() and User::setPassword(), deprecated in 1.27, have
	been removed. Use User::changeAuthenticationData() instead.
	* User::selectFields(), deprecated in 1.31, has been removed. Use
	User::getQueryInfo() instead.
	* The "legacy" serialization type in RESTBagOStuff, deprecated in 1.34,
	has been removed.
	* The populateContentModel.php maintenance script was removed. It has
	been replaced by the populateContentTables.php script.
	* The findHooks.php maintenance script, for the old hooks system, was removed.
	* (T257278) Calling MediaWiki\Shell\Command::restrict() will now overwrite
	any previous restrictions rather than adding to them, making it possible to
	disable the default restrictions.

	=== Deprecations in 1.35 ===
	* The PHPUnit4And6Compat class, used to provide compatibility with PHPUnit 4, is
	now deprecated. MediaWiki support for PHPUnit 4 ended with the removal of HHVM
	support.
	* LockManagerGroup::getDefault() and LockManagerGroup::getAny() are deprecated.
	They seem to be unused. Just use get() directly, and catch any exception.
	* AbstractBlock::getPermissionsError and AbstractBlock::getBlockErrorParams are
	deprecated. Use BlockErrorFormatter::getMessage instead.
	* The IP class is deprecated. Please instead use the Wikimedia\IPUtils class
	from the new wikimedia/ip-utils library instead. Additionally, the RE_IP_*
	constants are also deprecated. RE_IP_BYTE can be replaced with a class
	constant on the IPUtils class, while the others will eventually be made
	private.
	* The following Language methods are deprecated: getFallbackFor,
	getFallbacksFor, getFallbacksIncludingSiteLanguage. Use the corresponding new
	methods on the LanguageFallback class: getFirst, getAll, and
	getAllIncludingSiteLanguage.
	* FileJournal::factory is deprecated. Use the constructor directly instead.
	* AbstractBlock methods setBlocker(), getBlocker() are deprecated and will
	become internal implementation of DatabaseBlock.
	* Title::countRevisionsBetween has been deprecated and moved into RevisionStore.

	* GenderCache::singleton(), deprecated in 1.28, is hard deprecated. Use
	MediaWikiServices::getGenderCache() instead.
	* MediaWikiIntegrationTest::setContentLang() has been deprecated. Use
	setMwGlobals( 'wgLanguageCode', 'xxx' ) to set a different site language
	code, or setService( 'ContentLanguage', $myObj ) to set a specific Language
	object. Service resets and $wgContLang will be handled automatically.
	* MediaWikiIntegrationTest::assertType() has been deprecated, as part of the
	work to move to PHPUnit 8; PHPUnit's assertInternalType() was deprecated, and
	will be removed in PHPUnit 9. MediaWikiIntegrationTest::assertTypeOrValue(),
	a wrapper for assertType(), has been removed immediately, without deprecation.
	* AbstractBlock::getReason is deprecated, since reasons are actually stored as
	CommentStoreComments, and getReason returns a string with no caller control

	* The global function wfGetRusage() is deprecated and will now always call the
	getrusage() function without checking for its existence.

	instead.
	* DerivedPageDataUpdater::prepareUpdate accepted as its second parameter an
	optional array of options. Specifying the value of the `oldrevision` key of
	the array to be a Revision object, rather than a RevisionRecord object, is
	hard deprecated. The same applies to the options parameter in
	WikiPage::doEditUpdates.
	* Skin::makeI18nUrl() and makeNSUrl() have been deprecated, no longer used.
	* Title::countAuthorsBetween and Title::getAuthorsBetween were hard deprecated.

	parameter.
	* ApiBase::validateLimit() and ApiBase::validateTimestamp() are deprecated.
	Use ApiParamValidator::validateValue() with an appropriate settings array
	instead.
	* ContentHandler (use ContentHandlerFactory):

	No replacement; <section> tag wrapping will be done by core in future.
	- BeforeParserrenderImageGallery
	No replacement; MediaHandler provides for customizable media rendering

	fully on construction and so ::firstCallInit() no longer has any effect
	when manually invoked.
	- ParserOptions::setAllowExternalImages(), ::setAllowExternalImagesFrom(),

	These options no longer have any effect.
	- Most methods of MWTidy, except for MWTidy::tidy(), have been deprecated;
	tidiness is always enabled and not configurable.

	* ParserOptions::newCanonical() with no first parameter, or null as the first
	parameter, which falls back to using global $wgUser, is hard deprecated.
	* Parser::fetchCurrentRevisionOfTitle, ::statelessFetchRevision, and
	::getRevisionObject were hard deprecated in favor of the new
	::fetchCurrentRevisionRecordOfTitle, ::statelessFetchRevisionRecord,
	and ::getRevisionRecordObject methods respectively.
	* ParserOptions::getCurrentRevisionCallback and ::setCurrentRevisionCallback
	were hard deprecated in favor of the new ::getCurrentRevisionRecordCallback
	and ::setCurrentRevisionRecordCallback methods respectively.
	* Parser::statelessFetchTemplate returns an array; accessing the Revision
	object returned (via the `revision` key to the array) is deprecated. Instead,
	use `revision-record` to retrieve the equivalent RevisionRecord.
	* WikiPage::doEditContent returns an array, and PageUpdater::getStatus returns
	a Status object with an array value. For both of those arrays, accessing the
	Revision object returned (via the `revision` key to the array) is deprecated.
	Instead, use `revision-record` to retrieve the equivalent RevisionRecord.
	* Page interface was deprecated. Use Article or WikiPage instead.
	* The following DatabaseBlock methods are deprecated because they are no longer
	needed in core: chooseBlock, fromMaster, deleteIfExpired.
	* wfGetScriptUrl() was deprecated. The script URL should be configured rather
	than detected. wfScript() can be used to get a configured script URL.
	* Action::factory() with null $action argument is hard deprecated
	* The following methods of the User class were deprecated: getDefaultOptions,
	getDefaultOption, getOptions, getOption, getBoolOption, getIntOption,
	setOption, listOptionKinds, getOptionKinds, resetOptions. Use corresponding
	methods in UserOptionsLookup or UserOptionsManager service classes instead.
	* UserRetrieveNewTalks hook was deprecated without replacement.
	* User::getNewtalk and ::setNewtalk were hard deprecated. Use service
	TalkPageNotificationManager instead.
	* EditPage::matchSpamRegex and ::matchSummarySpamRegex were hard deprecated in
	favor of the new SpamChecker service.
	* Title::getNotificationTimestamp, User::clearNotification, and
	User::clearAllNotifications were deprecated in favor of the new
	WatchlistNotificationManager service.
	* SpecialPage::setListed() and SpecialPage::listed() were deprecated. Subclass
	UnlistedSpecialPage to set listed as false, and use SpecialPage::isListed()
	to get the value.
	* CategoryPage::getCategoryViewerClass() and ::setCategoryViewerClass() were
	deprecated.
	* MWHttpRequest and its subclasses PhpHttpRequest, CurlHttpRequest and
	GuzzleHttpRequest now require the timeout and connectTimeout options to
	always be specified, otherwise a deprecation warning will be raised. Most
	callers should use HttpRequestFactory which always sets these options.
	* Linker::normaliseSpecialPage() has been deprecated, instead make use of
	LinkRenderer::normalizeTarget().
	* SkinTemplate::getPersonalToolsList() was soft deprecated.
	* ChangeTags::truncateTagDescription() has been deprecated.
	* The following methods of the User class are deprecated: getGroups,
	getGroupMemberships, getEffectiveGroups, getAutomaticGroups,
	addGroup, removeGroup, getFormerGroups, getAllGroups, getImplicitGroups,
	addAutopromoteOnceGroups. Use the new UserGroupManager service instead.
	* The following methods of the UserGroupMembership class were deprecated:
	selectFields, getMembershipsForUser, getMembership, insert, delete,
	newFromRow, initFromRow, purgeExpired.
	Use the new UserGroupManager service instead.
	* wfWaitForSlaves() has been hard deprecated. Use LBFactory::waitForReplication
	instead. It was soft deprecated in 1.27.
	* BaseTemplate::getAfterPortlet and ::renderAfterPortlet have been deprecated in
	favor of the Skin::getAfterPortlet method. Skin::getAfterPortlet does not wrap
	the result in a div, callers are responsible for that.
	The hook BaseTemplateAfterPortlet, called by both methods has been deprecated
	as well and is replaced by SkinAfterPortlet.
	* Autopromote class has been soft deprecated and it's methods moved into
	UserGroupManager.
	* SkinTemplateBuildNavUrlsNav_urlsAfterPermalink hook has been deprecated.
	Use SidebarBeforeOutput hook and get the revision id from the OutputPage
	object.
	* BaseTemplate::getToolbox() method has been soft deprecated. The toolbox data
	is now available in a sidebar data array which you can get from any class
	that's extending QuickTemplate class. The hook associated with this method,
	BaseTemplateToolbox, has been hard deprecated. To add items to the toolbox,
	use SidebarBeforeOutput hook instead.
	* The SkinTemplateOutputPageBeforeExec hook is deprecated.
	The page [[mw:Manual:Hooks/SkinTemplateOutputPageBeforeExec]] and T60137
	for recommendations for alternative approaches based on how developers
	previously used this hook.
	* SkinTemplateToolboxEnd hook has been deprecated. Use SidebarBeforeOutput hook
	instead.

	deprecated. Use OutputPageBodyAttributes hook instead.
	* Installer::getDBTypes has been hard deprecated in favor of
	InstallerDBSupport::getDatabases
	* The hooks BeforeHttpsRedirect, CanIPUseHTTPS and UserRequiresHTTPS were
	deprecated, as part of a long-term plan to remove support for mixed
	HTTP/HTTPS wikis.
	* Skin::generateDebugHTML() has been hard deprecated. Call
	MWDebug::getHTMLDebugLog() directly.
	* ExternalStoreDB::getSlave(), soft deprecated in 1.34, was hard deprecated.
	Use ExternalStoreDB::getReplica() instead.
	* Less variables in mediawiki.ui/variables.less file that don't follow the
	standard variable naming scheme (compare WikimediaUI Base) including
	`@colorGray* variables have been deprecated. New variables are in place and
	aliases have been set. Replace occurrences and use the new variables instead.

	=== Other changes in 1.35 ===
	* A new maintenance script is added (purgeExpiredWatchlistItems.php) with which
	to delete expired watchlist items. These items will also be deleted during
	wiki editing if $wgWatchlistPurgeRate is > 0. This maintenance script only
	has effect if $wgWatchlistExpiry is true. It is recommended that a cronjob or
	similar be set up to run it at least daily.
	* Title::purgeSquid is deprecated. Use MediaWikiServices::getHtmlCacheUpdater.
	* SpecialVersion::getExtLicenseFileName() has been deprecated, use
	MediaWiki\ExtensionInfo::getLicenseFileNames() instead.
	* SpecialVersion::getExtAuthorsFileName() has been deprecated, use
	MediaWiki\ExtensionInfo::getAuthorsFileName() instead.
	* Migration to the new content storage schema is complete, all backwards
	compatibility code and duplication in the database have been removed.
	The old schema was a 1:1 relationship modeled by
	revision.text_id -> text.old_id. The new schema is a n:m relationship,
	revision.rev_id <- slots.slot_revision_id\|slots.slot_content_id ->
	content.content_id\|content.content_address -> text.old_id. The same applies
	to the archive table.
	The following fields were removed:
	- revision.rev_text_id, replaced by content.content_address
	- revision.rev_content_model, replaced by content.content_model,
	referencing content_models.model_id
	- revision.rev_content_format, replaced by automatic detecting in
	ContentHandler
	- archive.ar_text_id, replaced by content.content_address
	- archive.ar_content_model, replaced by content.content_model,
	referencing content_models.model_id
	- archive.ar_content_format, replaced by automatic detecting in
	ContentHandler
	* Migration to normalized storage of edit comments and user names is
	progressing. The following fields were unused and have been removed:
	- revision.rev_comment,
	replaced by rev_comment_id referencing comment.comment_id.
	- revision.rev_user and rev_user_text,
	replaced by rev_actor referencing actor.actor_id.
	Note that archive.ar_user, archive.ar_user_text, and archive.ar_comment
	had already been removed in previous releases.
	* The printableversion has been marked as deprecated per T167956.
	* (T30162, T245387) The installer supports using a Postgres server running
	on a custom port other than 5432.

	== Compatibility ==
	MediaWiki 1.35 requires PHP 7.3.19 or later, and the following PHP extensions:

	* ctype
	* dom
	* fileinfo
	* iconv
	* json
	* mbstring
	* xml

	MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
	but support for them is somewhat less mature.

	The supported versions are:

	* MySQL 5.5.8 or later
	* PostgreSQL 9.2 or later
	* SQLite 3.8.0 or later

	== Online documentation ==
	Documentation for both end-users and site administrators is available on

	* (T231366) The ProfilerOutputDb class, 'profiling' table, and profileinfo.php
	entry point had been deprecated.

	* (T234581) The 'jquery.tabIndex' module is deprecated.
	* Fix docs for GetUserBlock hooks.
	* Parser: Hard deprecate getConverterLanguage.
	* (T236810) A number of public methods of Parser were exposed only for

	* (T30798) $wgServer must now always be set in LocalSettings.php. This is most
	likely the case already for any wiki installed after 1.18. The autodetection
	system was informally deprecated since 1.18 and vulnerable to cache poisoning
	attacks. Older wikis may need to update their LocalSettings.php file.

	== MediaWiki 1.34.0-rc.0 ==

	== Upgrading notes for 1.34 ==
	1.34 has several database changes since 1.33, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions, including
	important information when upgrading from versions prior to 1.11.

	Some specific notes for MediaWiki 1.34 upgrades are below:

	* MediaWiki now requires PHP 7.2.9 or above.
	* MediaWiki no longer supports HHVM.

	For notes on 1.33.x and older releases, see HISTORY.

	=== Configuration changes for system administrators in 1.34 ===

	In an effort to enforce best practices for passwords, MediaWiki will now warn
	users, and suggest that they change their password, if it is in the list of
	100,000 commonly used passwords that are considered bad passwords. If you want
	to disable this for your users, please add the following to your local settings:

	$wgPasswordPolicy['policies']['default']['PasswordNotInLargeBlacklist'] = false;

	==== New configuration ====
	* $wgAllowExternalReqID (T201409) - This configuration setting controls whether
	MediaWiki accepts the request ID set by the incoming request via the
	`X-Request-Id` header. If set to `true`, that value will be used throughout
	the code as the request identificator. Otherwise, the sent header will be
	ignored and the request ID will either be taken from Apache's mod_unique
	module or will be generated by MediaWiki itself (depending on the set-up).
	* $wgEnableSpecialMute (T218265) - This configuration controls whether
	Special:Mute is available and whether to include a link to it on emails
	originating from Special:Email.
	* editmyuserjsredirect user right – users without this right now cannot edit JS
	redirects in their userspace unless the target of the redirect is also in
	their userspace. By default, this right is given to everyone.
	* (T226733) Add rate limiter to Special:ConfirmEmail.
	* $wgDiffEngine (T237049) – This configuration can be used to specify which
	difference engine to use. MediaWiki continues to default to automatically
	choosing the first of $wgExternalDiffEngine, wikidiff2, or php that is
	usable.

	==== Changed configuration ====
	* $wgUseCdn, $wgCdnServers, $wgCdnServersNoPurge, and $wgCdnMaxAge – These four
	CDN-related config variables have been renamed from being specific to Squid –
	they were previously $wgUseSquid, $wgSquidServers, $wgSquidServersNoPurge, and
	$wgSquidMaxage respectively. This aligns them with the related existing
	variable $wgCdnMaxageLagged. The previous configuration variable names are
	deprecated, but will be used as the fall back if they are still set.
	Note that wgSquidPurgeUseHostHeader has not been renamed, as it is deprecated.
	* (T27707) File type checks for image uploads have been relaxed to allow files
	containing some HTML markup in metadata. As a result, the $wgAllowTitlesInSVG
	setting is no longer applied and is now always true. Note that MSIE 7 may
	still be able to misinterpret certain malformed PNG files as HTML.
	* (T30798) $wgServer must now always be set in LocalSettings.php. This is most
	likely the case already for any wiki installed after 1.18. The autodetection
	system was informally deprecated since 1.18 and vulnerable to cache poisoning
	attacks. Older wikis may need to update their LocalSettings.php file.
	* Introduced $wgVerifyMimeTypeIE to allow disabling the MSIE 6/7 file type
	detection heuristic on upload, which is more conservative than the checks
	that were changed above.
	* $wgExternalDiffEngine — Setting this to a string value of 'wikidiff',
	'wikidiff2', or 'wikidiff3' will no longer work. This legacy behaviour was
	deprecated in MediaWiki 1.27, 1.32, and 1.27, respectively.
	* $wgSkipSkin — Setting this instead of $wgSkipSkins, deprecated in 1.23, is now
	hard-deprecated.
	* $wgLocalInterwiki — Setting this instead of $wgLocalInterwikis, deprecated in
	1.23, is now hard-deprecated.
	* $wgProfileOnly — Setting this, deprecated in 1.23, is now hard-deprecated.
	Instead, set the log file in $wgDebugLogGroups['profileoutput'].
	* $wgProxyList — Setting this to an array with IP addresses in the array keys,
	which was deprecated in 1.30, no longer works. Instead, $wgProxyList should be
	an array with IP addresses as the values, or a string path to a file
	containing one IP address per line.
	* $wgCookieSetOnAutoblock and $wgCookieSetOnIpBlock are now enabled by default.

	==== Removed configuration ====
	* $wgWikiDiff2MovedParagraphDetectionCutoff — If you still want a custom change
	size threshold, please specify in php.ini, using the configuration variable
	wikidiff2.moved_paragraph_detection_cutoff.
	* $wgUseESI - This experimental setting, deprecated in 1.33, is now removed.
	* $wgDebugPrintHttpHeaders - The default of including HTTP headers in the
	debug log channel is no longer configurable. The debug log itself remains
	configurable via $wgDebugLogFile.
	* $wgMsgCacheExpiry - The MessageCache uses 24 hours as the expiry for values
	stored in WANObjectCache. This is no longer configurable.
	* $wgPasswordSalt – This setting, used for migrating exceptionally old, insecure
	password setups and deprecated since 1.24, is now removed.
	* $wgDBOracleDRCP - If you must use persistent connections, set DBO_PERSISTENT
	in the 'flags' field for servers in $wgDBServers (or $wgLBFactoryConf).
	* $wgMemCachedDebug - Set the cache "debug" field in $wgObjectCaches instead.
	* $wgActorTableSchemaMigrationStage has been removed. Extension code for
	MediaWiki 1.31+ finding it unset should treat it as being SCHEMA_COMPAT_NEW.

	=== New user-facing features in 1.34 ===
	* Special:Mute has been added as a quick way for users to block unwanted emails
	from other users originating from Special:EmailUser.
	* (T207577) Special:NewSection has been created as a shortcut to creating a new
	section on a page. When linked to, its subpage is used as the target
	([[Special:NewSection/Test]] redirects to creating a new section in "Test").
	Otherwise, it displays a basic interface to allow the end user to specify
	the target manually.
	* (T220447) Special:Contributions/newbies has been removed for performance and
	usefulness reasons. Use Special:RecentChanges?userExpLevel=newcomer instead.

	=== New developer features in 1.34 ===
	* The ImgAuthModifyHeaders hook was added to img_auth.php to allow modification
	of headers in private wikis.
	* Language::formatTimePeriod now supports the new 'avoidhours' option to output
	strings like "5 days ago" instead of "5 days 13 hours ago".
	* (T220163) Added SpecialMuteModifyFormFields hook to allow extensions
	to add fields to Special:Mute.
	* (T100896) Skin authors can define custom OOUI themes using OOUIThemePaths.
	See <https://www.mediawiki.org/wiki/OOUI/Themes> for details.
	* (T229035) The GetUserBlock hook was added. Use this instead of
	GetBlockedStatus.
	* ObjectFactory is available as a service. When used as a service, the object
	specs can now specify needed DI services.
	* (T222388) Special pages can now be specified as an ObjectFactory spec,
	allowing the construction of special pages that require services to be
	injected in their constructor.
	* (T222388) API modules can now be specified as an ObjectFactory spec,
	allowing the construction of modules that require services to be injected
	in their constructor.
	* (T117736) The function signature of SpecialContributions::getForm::filters
	has changed. It now expects definitions of additional filter fields as array
	rather than string.

	==== Removed external libraries ====
	* The jquery.async module, deprecated in 1.33, was removed.

	=== Bug fixes in 1.34 ===
	* (T222529) If a log entry or page revision is recorded in the database with an
	empty username, attempting to display it will log an error and return a "no
	username available" to the user instead of silently displaying nothing or
	invalid links.

	=== Action API changes in 1.34 ===
	* The 'recenteditcount' response property from action=query list=allusers,
	deprecated in 1.25, has been removed.
	* (T60993) action=query list=filearchive, list=alldeletedrevisions and
	prop=deletedrevisions no longer require the 'deletedhistory' user right.
	* In the response to queries that use 'prop=imageinfo', entries for
	non-existing files (indicated by the 'filemissing' field) now omit the
	following fields, since they are meaningless in this context:
	'timestamp', 'userhidden', 'user', 'userid', 'anon', 'size', 'width',
	'height', 'pagecount', 'duration', 'commenthidden', 'parsedcomment',
	'comment', 'thumburl', 'thumbwidth', 'thumbheight', 'thumbmime',
	'thumberror', 'url', 'sha1', 'metadata', 'extmetadata', 'commonmetadata',
	'mime', 'mediadtype', 'bitdepth'.
	Clients that process these fields should first check if 'filemissing' is
	set. Fields that are supported even if the file is missing include:
	'canonicaltitle', 'archivename' (deleted files only), 'descriptionurl',
	'descriptionshorturl'.
	* The 'blockexpiry' result property in list=users and list=allusers will now be
	returned in the same format used by the rest of the API: ISO 8601 for
	expiring blocks, and "infinite" for non-expiring blocks.

	=== Action API internal changes in 1.34 ===
	* The exception thrown in ApiModuleManager::getModule has been changed
	from an MWException to an UnexpectedValueException, thrown by ObjectFactory.
	ApiModuleManager::getModule now also throws InvalidArgumentExceptions when
	ObjectFactory is presented with an invalid spec or incorrectly constructed
	objects.
	* Added ApiQueryBlockInfoTrait.

	=== Languages updated in 1.34 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* (T152908) Added language support for N'Ko (nqo).

	=== Breaking changes in 1.34 ===
	* The global functions wfSuppressWarnings and wfRestoreWarnings, deprecated in
	1.26, have been removed. Use Wikimedia\AtEase\AtEase::suppressWarnings() and
	Wikimedia\AtEase\AtEase::restoreWarnings() directly.
	* Preferences class, deprecated in 1.31, has been removed.
	* The following parts of code, deprecated in 1.32, were removed in favor of
	built-in PHP functions:
	* CryptRand class
	* CryptRand service
	* Functions of the MWCryptRand class: singleton(), wasStrong() and generate().
	* Various Special Page PHP Classes were renamed (mostly casing changes):
	* SpecialAncientpages => SpecialAncientPages
	* SpecialConfirmemail => SpecialConfirmEmail
	* SpecialDeadendpages => SpecialDeadendPages
	* SpecialFewestrevisions => SpecialFewestRevisions
	* SpecialListredirects => SpecialListRedirects
	* SpecialLonelypages => SpecialLonelyPages
	* SpecialLongpages => SpecialLongPages
	* SpecialMIMEsearch => SpecialMIMESearch
	* SpecialMostcategories => SpecialMostCategories
	* SpecialMostinterwikis => SpecialMostInterwikis

	create a new Language object with a different language code.
	* MWNamespace::clearCaches() has been removed. So has the $rebuild parameter
	to MWNamespace::getCanonicalNamespaces(), which was deprecated since 1.31.
	Instead, reset services, such as by calling $this->overrideMwServices() (if
	your test extends MediaWikiTestCase). Services will generally not pick up
	configuration changes from after they were created, so you must reset
	services after any configuration change. Even if your code works now, it is
	likely to break in future versions as more code is moved to services.
	* The ill-defined "DatabaseOraclePostInit" hook has been removed.
	* PreferencesFormLegacy and PreferencesForm classes, deprecated in 1.32, have
	been removed.

	* The 'recenteditcount' response property from action API action=query
	list=allusers, deprecated in 1.25, has been removed.

	* EditPage::safeUnicodeInput() and ::safeUnicodeOutput(), deprecated in 1.30,
	have been removed.

	::showFileNotFoundError().
	* ApiBase::truncateArray(), deprecated in 1.32, has been removed.
	* IcuCollation::getICUVersion(), deprecated in 1.32, has been removed. Use PHP's
	INTL_ICU_VERSION constant directly.
	* HTMLForm::setSubmitProgressive(), deprecated in 1.32, has been removed.
	* ResourceLoaderStartUpModules::getStartupModules() and ::getLegacyModules(),
	both deprecated in 1.32, have been removed.

	$mParentBlockId. To check for an autoblock use DatabaseBlock::getType; to
	check for the parent ID, use DatabaseBlock::getParentBlockId.
	* SearchEngine::userHighlightPrefs() is deprecated, simply stop passing
	$contextlines and $contextchars to the SearchHighlighter methods, they will
	use proper defaults defined in SearchHighlighter::DEFAULT_CONTEXT_LINES and
	DEFAULT_CONTEXT_CHARS.
	* SearchUpdate constructor: passing a string as the title param and or a boolean
	or a string as the content will produce a deprecation warning.
	* SearchEngine::getTextFromContent() is deprecated, use getTextForSearchIndex()
	directly from the Content object.
	* SearchEngine::textAlreadyUpdatedForIndex() is deprecated, given the
	deprecation above this method is no longer needed/called and should not be
	implemented by SearchEngine implementation.
	* IDatabase::bufferResults() has been deprecated. Use query batching instead.
	* MessageCache::singleton() is deprecated. Use
	MediaWikiServices::getMessageCache().
	* ObjectCache::getWANInstance() is deprecated. Use
	MediaWikiServices::getMainWANObjectCache() instead.
	* ObjectCache::newWANCacheFromParams() is deprecated. Use
	MediaWikiServices::getMainWANObjectCache() instead.
	* Constructing MovePage directly is deprecated. Use MovePageFactory.
	* TempFSFile::factory() has been deprecated. Use TempFSFileFactory instead.
	* wfIsBadImage() is deprecated. Use the BadFileLookup service instead.
	* Building a new SearchResult is hard-deprecated, always call
	SearchResult::newFromTitle(). This class is being refactored into an abstract
	class. If you extend this class please be sure to override all its methods
	or extend RevisionSearchResult.
	* Skin::getSkinNameMessages() is deprecated and no longer used.
	* The mediawiki.RegExp module is deprecated; use mw.util.escapeRegExp() instead.
	* Specifying a SpecialPage object for the list of special pages (either through
	the SpecialPage_initList hook or by adding to $wgSpecialPages) is now
	deprecated.
	* The 'jquery.tabIndex' module is deprecated.
	* WebInstaller::getWarningBox() and getErrorBox() are deprecated.
	Use Html::errorBox() or Html::warningBox() instead.
	* Use of ActorMigration with 'ar_user', 'img_user', 'oi_user', 'fa_user',
	'rc_user', 'log_user', and 'ipb_by' is deprecated. Queries should be adjusted
	to use the corresponding actor fields directly. Note that use with
	'rev_user' is not deprecated at this time.
	* Specifying both the class and factory parameters for
	ApiModuleManager::addModule is now deprecated. The ObjectFactory spec should
	be used instead.
	* The UserIsHidden hook is deprecated. Use GetUserBlock instead, and add a
	system block that hides the user.
	* The GetBlockedStatus hook is deprecated. Use GetUserBlock instead, to add or
	remove a block.
	* $wgContentHandlerUseDB is deprecated and should always be true.
	* StreamFile::send404Message() and StreamFile::parseRange() are now deprecated.
	Use HTTPFileStreamer::send404Message() and HTTPFileStreamer::parseRange()
	respectively instead.
	* Global variable $wgSysopEmailBans is deprecated; to allow sysops to ban
	users from sending emails, use
	$wgGroupPermissions['sysop']['blockemail'] = true;
	* ApiQueryBase::showHiddenUsersAddBlockInfo() is deprecated. Use
	ApiQueryBlockInfoTrait instead.
	* PasswordReset is now a service, its direct instantiation is deprecated.
	* RESTBagOStuff users should specify either "JSON" or "PHP" serialization type.
	* The global function wfIsHHVM() is deprecated and will now always return false
	regardless of the runtime environment. This is part of the continuing work to
	remove HHVM support from MediaWiki, which started in MediaWiki 1.31.
	* Language::getLocalisationCache() is deprecated. Use MediaWikiServices
	instead.
	* The following Language methods are deprecated: isSupportedLanguage,
	isValidCode, isValidBuiltInCode, isKnownLanguageTag, fetchLanguageNames,
	fetchLanguageName, getFileName, getMessagesFileName, getJsonMessagesFileName.
	Use the new LanguageNameUtils class instead. (Note that fetchLanguageName(s)
	are called getLanguageName(s) in the new class.)
	* Using the Parser without initializing its $mTitle property to non-null has
	been deprecated. In a future release Parser::getTitle() will throw a
	TypeError if $mTitle is uninitialized.
	* A number of public methods of Parser were exposed only for historical
	reasons and have been deprecated: doMagicLinks, doDoubleUnderscore,
	doHeadings, doAllQuotes, replaceExternalLinks, replaceInternalLinks,
	replaceInternalLinks2, getVariableValue, initialiseVariables, formatHeadings,
	testPst, testPreprocess, testSrvus, areSubpagesAllowed, maybeDoSubpageLink,
	splitWhitespace, createAssocArgs, armorLinks, makeKnownLinkHolder,
	getImageParams, parseLinkParameter, stripAltText, replaceLinkHolders,
	replaceLinkHoldersText, armorLinks, makeKnownLinkHolder, getImageParams,
	parseLinkParameter, stripAltText.

	=== Other changes in 1.34 ===
	* Added option to specify "Various authors" as author in extension credits using
	"..." as the only author name. If the "author" array contains more than one
	entry and "..." is one of the entries in the array, "..." will be parsed as
	"others" (version-poweredby-others i18n message) like previously.
	* (T232563) Browser support ("Grade C") for Internet Explorer 6 and 7
	was discontinued. Basic content and security features may no longer

	=== Upgrading notes for 1.33 ===
	1.33 has several database changes since 1.32, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions, including
	important information when upgrading from versions prior to 1.11.

	Some specific notes for MediaWiki 1.33 upgrades are below:

	* Some external link searches will not work correctly until update.php (or
	refreshExternallinksIndex.php) is run. These include searches for links using
	IP addresses, internationalized domain names, and possibly mailto links.
	* If you ran migrateActors.php using an older version of MediaWiki and want to
	run your wiki with $wgActorTableSchemaMigrationStage SCHEMA_COMPAT_READ_OLD,
	note that log_search rows needed to find revision deletions by target user
	were incorrectly deleted. See T215464 for details.
	* If revision deletions were performed when the wiki was configured with
	$wgActorTableSchemaMigrationStage SCHEMA_COMPAT_WRITE_BOTH and without
	migrateActors.php having been run, the log_search table may contain rows with
	empty values for "target_author_actor" which will prevent log searches for
	revision deletions by target user from finding those log entries. These rows
	may be corrected by (re-)running migrateActors.php.

	For notes on 1.32.x and older releases, see HISTORY.

	== MediaWiki 1.33.0 ==

	=== Changes since MediaWiki 1.33.0-rc.0 ===

	tables.
	* (T225564) Fetch tag ID before calling undefineTag().
	* (T225496) Detect APC for MainCacheType in CLI installer.
	* Call unpack() with correct parameters in MimeAnalyzer.php for PHP 7.0 support.
	* (T212613) Style change tags correctly on Special:Newpages.
	* (T202211) Fix SQLite patch-(page\|template)links-fix-pk.sql column order.

	== MediaWiki 1.33.0-rc.0 ==

	=== Configuration changes for system administrators in 1.33 ===
	==== New configuration ====
	* $wgEnablePartialBlocks – This enables the Partial Blocks feature, which gives
	accounts with block permissions the ability to block users, IPs, and IP ranges
	from editing specific pages, while allowing them to edit the rest of the wiki.
	It is a temporary setting for gradual enablement, current default to `false`,
	and will be set to `true` and then removed once initial development completes.

	==== Changed configuration ====
	* $wgChangeTagsSchemaMigrationStage (T193868) — This temporary setting, added in
	MediaWiki 1.32, now defaults to MIGRATION_NEW instead of MIGRATION_WRITE_BOTH.
	* $wgPasswordPolicy – There is a new password policy to check that the account's
	password is not in the large blacklist. This is enabled by default for the
	built-in user groups bureaucrat, sysop, interface-admin, and bot. To configure
	this for other user groups, set the `PasswordNotInLargeBlacklist` flag `true`.
	* $wgPasswordDefault – There is a new password type configuration using Argon2
	password hashing (which requires PHP 7.2 and above). It's designed to resist
	timing attacks, and (on systems with PHP 7.3+) GPU hacking; if you configure
	argon2 to be used, by default, it will automatically choose the best available
	algorithm depending on which version of PHP you have available. To use this,
	you can set `$wgPasswordDefault = 'argon2';`.
	* $wgActorTableSchemaMigrationStage now defaults to reading the new schema.
	update.php will back-populate the new database fields due to the changed
	setting, which may take some time on large wikis. You can avoid downtime by
	following a process like that described in T188327.

	==== Removed configuration ====
	* $wgTagStatisticsNewTable (T199334) — This temporary setting, added in
	MediaWiki 1.32, has now been removed. When loading Special:Tags, MediaWiki
	will now always use the `change_tag_def` instead of the `change_tag` table.
	* $wgUseTidy, $wgTidyBin, $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and
	$wgDebugTidy – These options, all deprecated since 1.26, have now all been
	removed, as MediaWiki now always tidies user output. The $wgTidyConfig setting
	remains only for experimental features and debugging, and should not be used.
	* $wgEnableParserCache – This setting has been deprecated since 1.26, has now
	been removed. If you still desire to disable the parser cache, instead you can
	set `$wgParserCacheType = CACHE_NONE;`.
	* $wgCommentTableSchemaMigrationStage – This temporary migration setting has now
	been removed. Code finding it unset should treat it as being MIGRATION_NEW.
	* $wgAuth – This old setting, deprecated in 1.27, has been removed as part of
	the removal of AuthPlugin.
	* $wgSitesCacheFile – This configuration was introduced in 1.25 with the intent
	to allow sites to configure a file in which to cache the SiteStore database
	table, but it was never used. SiteStore already caches its information by
	default using BagOStuff (e.g. Memcached or APC).
	* $wgClockSkewFudge – This setting was used by User.php to let sites adjust by
	how much MediaWiki would fudge when trying to minimize the chances of a
	user.user_touched database update to the "current" timestamp being before the
	value already there (e.g. due to clock skew between different servers). This
	is no longer a problem, because the code now ensures the timestamp is always
	higher than the previous one. The writes are guarded with CAS logic (check
	and set), which prevents updates that would overlap.
	* $wgDBmysql5 (T196185) - This experimental setting, deprecated in 1.31, has
	been removed.

	=== New user-facing features in 1.33 ===
	* (T96041) __EXPECTUNUSEDCATEGORY__ on a category page causes the category
	to be hidden on Special:UnusedCategories.
	* (T210814) SVGs are now by default displayed in wiki language on image
	pages.
	* Special:CreateAccount now warns the user if their chosen username has to be
	normalized.
	* (T205040) Multilingual images are now be displayed in the current parse
	language where available.
	* Special:ActiveUsers will no longer filter out users who became inactive since
	the last time the active users query cache was updated.
	* (T215675) RecentChange and ManualLogEntry implement new Taggable interface.
	* (T215675) Added a hook, ManualLogEntryBeforePublish, to allow extensions
	to modify (example: add tags) log entries.

	=== New developer features in 1.33 ===
	* The AuthManagerLoginAuthenticateAudit hook has a new parameter for
	additional information about the authentication event.
	* TextContent::getText() was introduced as a replacement for
	Content::getNativeData() for text-based content models.
	* (T214706) LinksUpdate::getAddedExternalLinks() and
	LinksUpdate::getRemovedExternalLinks() were introduced.
	* (T213893) Added 'MaintenanceUpdateAddParams' hook
	* (T219655) The MarkPatrolled hook has a new parameter for the tags
	associated with this entry in the patrol log.
	* (T212472) Extensions can now specify platform abilities they require to work,
	limited to shell access for now.


	=== External library changes in 1.33 ===

	=== Bug fixes in 1.33 ===
	* (T164211) Special:UserRights could sometimes fail with a
	"conflict detected" error when there weren't any conflicts.
	* (T216029) Chrome redirects to Special:BadTitle after editing a section with
	a non-Latin name on a page with non-Latin characters in title.
	* (T222385) resourceloader: Use AND instead of OR for upsert conds in
	saveFileDependencies().

	=== Action API changes in 1.33 ===
	* (T198913) Added 'ApiOptions' hook.
	* The JSON formatversion=2 is no longer experimental.
	* Internal API errors (those with code beginning "internal_api_error") will
	include the exception class name in a data field named "errorclass".
	* Class names are not guaranteed to remain stable, and in particular database
	exceptions will now include the "Wikimedia\Rdbms\" prefix in the class name.
	* The code including an exception class name is deprecated. In the future,
	all internal errors will use code "internal_api_error".
	* (T212356) When using action=delete on pages with many revisions, the module
	may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
	deletion will be processed via the job queue.
	* action=setnotificationtimestamp will now update the watchlist asynchronously
	if entirewatchlist is set, so updates may not be visible immediately
	* Block info will be added to "blocked" errors from more modules.
	* (T216245) Autoblocks will now be spread by action=edit and action=move.
	* action=query&meta=userinfo has a new uiprop, 'latestcontrib', that returns
	the date of user's latest contribution.
	* (T25227) action=logout now requires to be posted and have a csrf token.

	=== Action API internal changes in 1.33 ===
	* A number of deprecated methods for API documentation, intended for overriding
	by extensions, are no longer called by MediaWiki, and will emit deprecation
	notices if your extension attempts to use them:
	* ApiBase::getDescription() (deprecated in 1.25)
	* ApiBase::getParamDescription() (deprecated in 1.25)
	* ApiBase::getExamples() (deprecated in 1.25)
	* ApiBase::getDescriptionMessage() (deprecated in 1.30)
	Additionally, the 'APIGetDescription' and 'APIGetParamDescription' hooks have
	been removed, as their only use was to let extensions override values returned
	by getDescription() and getParamDescription(), respectively.
	* API error codes may only contain ASCII letters, numbers, underscore, and
	hyphen. Methods such as ApiBase::dieWithError() and
	ApiMessageTrait::setApiCode() will throw an InvalidArgumentException if
	passed a bad code.
	* ApiBase::checkTitleUserPermissions() now takes an options array as its third
	parameter. Passing a User object or null is deprecated.
	* The api-feature-usage log channel now has log context. The text message is
	deprecated and will be removed in the future.

	=== Languages updated in 1.33 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* The parameteter $lang in DifferenceEngine::setTextLanguage must be of type
	Language. Other types are deprecated since 1.32.
	* Skin::doEditSectionLink requires type Language for the parameter $lang.
	The parameters $tooltip and $lang are mandatory. Omitting the parameters is
	deprecated since 1.32.
	* Language::truncate(), deprecated in 1.31, has been removed.
	* UtfNormal, deprecated in 1.25, was removed. Use UtfNormal\Validator directly
	instead.
	* (T197179) In OOUI HTMLForm fields, the parameters 'notice', 'notice-messages',
	and 'notice-message', which were deprecated in 1.32, were removed. Instead,
	use 'help', 'help-message', and 'help-messages'.
	* (T197179) HTMLFormField::getNotices(), deprecated in 1.32, was removed.
	* The "Parsoid v1" compatibility mappings in ParsoidVirtualRESTService and
	RestbaseVirtualRESTService, deprecated since 1.26, have been removed.
	Use the RESTBase v1 or Parsoid v3 API instead.
	* ParserOptions defaults 'tidy' to true now, since the untidy modes of the
	parser are being deprecated and ParserOptions::getCanonicalOverrides()
	has always been true at any rate.
	* Support for disabling tidy and external tidy implementations has been removed.
	This was deprecated in 1.32. The pure PHP Remex tidy implementation is now
	used and no configuration is necessary.
	* A number of deprecated methods for API documentation, intended for overriding
	by extensions, are no longer called by MediaWiki, and will emit deprecation
	notices if your extension attempts to use them:
	* ApiBase::getDescription() (deprecated in 1.25)
	* ApiBase::getParamDescription() (deprecated in 1.25)
	* ApiBase::getExamples() (deprecated in 1.25)
	* ApiBase::getDescriptionMessage() (deprecated in 1.30)
	Additionally, the 'APIGetDescription' and 'APIGetParamDescription' hooks have
	been removed, as their only use was to let extensions override values returned
	by getDescription() and getParamDescription(), respectively.
	* The authentication hooks 'AbortAutoAccount' 'AbortNewAccount', 'AbortLogin',
	'LoginUserMigrated', 'UserCreateForm', and 'UserLoginForm', all deprecated by
	the creation of AuthManager in 1.27, have been removed. This also means that
	the FakeAuthTemplate and LoginForm classes are removed, that FakeAuthTemplate
	is no longer passed into LoginSignupSpecialPage->getFieldDefinitions(), and
	that LoginSignupSpecialPage->getBCFieldDefinitions() is removed.
	* The 'jquery.localize' module, deprecated in 1.32, has been removed. Instead,
	use 'jquery.i18n'.
	* The hooks LanguageGetSpecialPageAliases and LanguageGetMagic, deprecated since
	1.16, have now been removed. Instead, use $specialPageAliases or $magicWords
	respectively in a $wgExtensionMessagesFiles file.
	* The following methods of the Preferences class, deprecated in 1.31, have been
	removed:
	* getSaveBlacklist()
	* loadPreferenceValues()
	* getOptionFromUser()
	* profilePreferences()
	* skinPreferences()
	* filesPreferences()
	* datetimePreferences()
	* renderingPreferences()

	mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
	mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,

	wgSessionHandler, both of which were deprecated in 1.27 with the introduction
	of SessionManager, has been removed.

	* The 'jquery.mockjax' module has been removed.
	* The 'jquery.hidpi' module, deprecated in 1.32, has been removed.
	* AuthPlugin and related code, deprecated in 1.27, has been removed. Extensions
	should instead use AuthManager. The following no longer exist:
	* The AuthPlugin class itself and the related AuthPluginUser class and i18n
	* The AuthPluginSetup and AuthPluginAutoCreate hooks
	* The transitional wrapper classes AuthPluginPrimaryAuthenticationProvider,
	AuthManagerAuthPlugin, and AuthManagerAuthPluginUser.
	* The $wgAuth configuration setting and its use in Setup.php and unit tests
	* (T217772) The 'wgAvailableSkins' mw.config key in JavaScript, was removed.

	* Handling of multiple arguments by the Block constructor, deprecated in 1.26,
	has been removed.
	* The translation of main page in Sardinian (sc) was changed from "Pàgina Base"
	to "Pàgina printzipale". Existing wikis using this content language need to
	move the main page or change the name through MediaWiki:Mainpage page.
	* wfSplitWikiID(), deprecated in 1.32, has been removed.
	* MessageBlobStore::getBlob(), deprecated in 1.27, has been removed.

	removed. Use MediaWikiTestCase::overrideMwServices() instead.
	* Support for the 'aggregator' option of JobQueue (and thus $wgJobTypeConf) was
	removed. The JobQueueAggregator interface and JobQueueAggregatorRedis class
	have also been removed. They were experimentally developed for use by the
	Wikimedia Foundation, but were never used, with no known use cases. (Note that
	this does not affect JobQueueRedis which is still supported.)

	=== Deprecations in 1.33 ===
	* The configuration option $wgUseESI has been deprecated, and is expected
	to be removed in a future release.
	* The configuration option $wgSquidPurgeUseHostHeader has been deprecated,
	and is expected to be removed in a future release.
	* The configuration options $wgFixArabicUnicode and $wgFixMalayalamUnicode,
	introduced in MW 1.17, have been deprecated. These fixes will always be
	applied for Arabic and Malayalam in the future. Please enable these on
	your local wiki (if you have them explicitly set to false) and run
	maintenance/cleanupTitles.php to fix any existing page titles.
	* The LegacyHookPreAuthenticationProvider class, deprecated since its creation
	in 1.27 as part of the AuthManager re-write, now emits deprecation warnings.
	This will help identify the issue if you added it to $wgAuthManagerConfig.
	* wfSplitWikiId() is now deprecated. Cache key generation should have the wiki
	domain ID as a key component and use makeGlobalKey().
	* (T202094) Title::getUserCaseDBKey() is deprecated; instead, please use
	Title::getDBkey(), which doesn't vary case.
	* User::getPasswordValidity() is now deprecated. User::checkPasswordValidity()
	returns the same information in a more useful format.
	* For Linker::generateTOC() and Linker::tocList(), passing strings or booleans
	as the $lang parameter was deprecated. The same applies to DummyLinker.
	* The PasswordPolicy 'PasswordCannotBePopular' has been deprecated. To
	follow best practices, it is reccommended to use 'PasswordNotInLargeBlacklist'
	instead which blacklists 100,000 commonly used passwords.
	* (T208862) Action::requiresUnblock() is now called from
	Title::getUserPermissionsErrors() and Title::userCan(). Previously, the method
	was only called in Action::checkCanExecute(). Actions should ensure that their
	requiresUnblock() returns the proper result (the default is `true`).
	* (T211608) The MediaWiki\Services namespace has been renamed to
	Wikimedia\Services. The old name is still supported, but deprecated.
	* (T155582) Content::getNativeData has been deprecated. Please use model-
	specific getters, such as TextContent::getText().
	* The class WebInstallerOutput is now marked as @private.
	* (T209699) The jquery.async module has been deprecated. JavaScript code that
	needs asynchronous behaviour should use Promises.
	* Password::equals() is deprecated, use verify().
	* BaseTemplate::msgWiki() and QuickTemplate::msgWiki() will be removed. Use
	other means to fetch a properly escaped message string or Message object.
	* (T126091) The 'ResourceLoaderTestModules' hook, which lets you declare QUnit
	testing code for your JavaScript modules, is deprecated. Instead, you can now
	use the new extension registration key 'QUnitTestModule'.
	* (T213426) The jquery.throttle-debounce module has been deprecated. JavaScript
	code that needs this behaviour should use OO.ui.debounce/throttle.
	* The mw.language.specialCharacters property from the
	'mediawiki.language.specialCharacters' module has been deprecated.
	Use require( 'mediawiki.language.specialCharacters' ) instead.
	* ChangeTags::purgeTagUsageCache() has been deprecated, and is expected to be
	removed in a future release.
	* Passing a User object or null as the third parameter to
	ApiBase::checkTitleUserPermissions() has been deprecated. Pass an array
	[ 'user' => $user ] instead.
	* (T211578) Block::prevents is deprecated. Use Block::isEmailBlocked,
	Block::isCreateAccountBlocked and Block::isUsertalkEditAllowed to get and set
	block properties; use Block::appliesToRight and Block::appliesToUsertalk to
	check block behaviour.
	* The api-feature-usage log channel now has log context. The text message is
	deprecated and will be removed in the future.
	* The FileBasedSiteLookup class has been deprecated. For a cacheable SiteLookup
	implementation, use CachingSiteStore instead.
	* Language::viewPrevNext function is deprecated, use
	SpecialPage::buildPrevNextNavigation instead
	* ManualLogEntry::setTags() is deprecated, use ManualLogEntry::addTags()
	instead. The setTags() method was overriding the tags, addTags() doesn't
	override, only adds new tags.
	* Block::isValid is deprecated, since it is no longer needed in core.
	* Calling Maintenance::hasArg() as well as Maintenance::getArg() with no
	parameter has been deprecated. Please pass the argument number 0.
	* ResourceLoaderContext::expandModuleNames has been deprecated.
	Use ResourceLoader::expandModuleNames instead.

	=== Other changes in 1.33 ===
	* (T201747) Html::openElement() warns if given an element name with a space
	in it.
	* The implementation of buildStringCast() in Wikimedia\Rdbms\Database has
	changed to explicitly cast. Subclasses relying on the base-class
	implementation should check whether they need to override it now.
	* BagOStuff::add is now abstract and must explicitly be defined in subclasses.
	* LinksDeletionUpdate is now a subclass of LinksUpdate. As a consequence,
	the following hooks will now be triggered upon page deletion in addition
	to page updates: LinksUpdateConstructed, LinksUpdate, LinksUpdateComplete.
	LinksUpdateAfterInsert is not triggered since deletions do not cause
	insertions into links tables.
	* Category::newFromID( $id )->getID() will now return $id without any
	validation, to avoid a mostly unnecessary DB query.
	* On Special:Version, the name for an extension can no longer be arbitrary
	html when no link is specified.

	=== Configuration changes in 1.32 ===

	==== New configuration ====
	* $wgJpegQuality – The quality of JPEG thumbnails is now configurable through
	this setting. The default is 80, which matches the quality of JPEG thumbnails
	previously generated by ImageMagick. The quality of JPEG thumbnails generated
	by GD was previously 95, but now uses the $wgJpegQuality setting as well.
	* $wgCookieSetOnIpBlock - This determines whether to set a cookie when an IP
	user is blocked. Doing so means that a blocked user, even after moving to a
	new IP address, will still be blocked.
	* $wgRawHtmlMessages – This new configuration setting is added for listing
	messages which are displayed as raw HTML.
	* $wgCSPHeader and $wgCSPReportOnlyHeader – You can now define a
	"Content Security Policy" for your wiki. This adds a defense-in-depth feature
	to stop an attacker who has found a bug in the parser allowing them to insert
	malicious attributes. Disabled by default. (T135963)
	* $wgGroupPermissions – A new user group, 'interface-admin', is added for
	controlling access to sitewide CSS/JS (and editing other users' CSS/JS). No
	other group has 'editsitecss', 'editusercss', 'editsitejs' or 'edituserjs'
	by default.
	* $wgGrantPermissions – A new grant group, 'editsiteconfig', is added for
	granting the above rights.
	* $wgDBDefaultGroup – A default database group for use by maintenance scripts.
	* $wgResourceLoaderEnableJSProfiler – This new configuration setting lets you
	enable client-side profiling of JavaScript modules; it is off by default.
	* (T193868) $wgChangeTagsSchemaMigrationStage — This temporary configuration
	setting allows sysadmins to gradually migrate the database table schema for
	how change tags are stored.
	* (T199334) $wgTagStatisticsNewTable — This temporary configuration setting
	allows sysadmins to enable the caching of Special:Tags via the new
	change_tag_def table.

	==== Changed configuration ====
	* $wgUseAjax – This setting, deprecated in 1.31, is now ignored.
	* $wgDefaultUserOptions – The default watchlist view time (watchlistdays) has
	been increased from 3 to 7 days. (T194414)
	* $wgGroupPermissions – The right to edit sitewide Javascript
	(e.g. MediaWiki:Common.js), CSS or JSON was separated from 'editinterface'
	and is available under 'editsitejs'/'editsitecss'/'editsitejson'. Having
	'editinterface' is still necessary to edit such pages.
	* $wgMultiContentRevisionSchemaMigrationStage now defaults to writing both the
	old and the new schema, but reading the new schema, so Multi-Content Revisions
	(MCR) are now functional by default. The new default value of the setting is
	SCHEMA_COMPAT_WRITE_BOTH \| SCHEMA_COMPAT_READ_NEW.
	* $wgActorTableSchemaMigrationStage no longer accepts MIGRATION_WRITE_BOTH or
	MIGRATION_WRITE_NEW. It instead uses SCHEMA_COMPAT_WRITE_BOTH \|
	SCHEMA_COMPAT_READ_OLD and SCHEMA_COMPAT_WRITE_BOTH \| SCHEMA_COMPAT_READ_NEW
	for intermediate stages of migration.
	* $wgDBTableOptions – The default table options now use the binary charset. The
	default was already overridden in the installer-generated LocalSettings.php,
	and so is always set to binary after the installer UI option was removed. The
	default value is only used when the installer installs an extension.
	* $wgPopularPasswordFile — The location of the default popular passwords file
	has been moved to be in line with other non-PHP files used by libraries and
	classes.
	* $wgEnableImageWhitelist is now disabled by default, as it opens up a hole for
	potential privacy leaks by administrators. You can check
	"MediaWiki:External image whitelist" on your wiki to see whether the feature
	was ever used, and whether it needs to be re-enabled.

	==== Removed configuration ====
	* $wgEnableAPI and $wgEnableWriteAPI – These settings, deprecated in 1.31,
	have been removed. (T115414)
	* $wgSiteSupportPage – This setting, unused since 1.5, was removed.
	* $wgBrowserBlacklist – This setting, deprecated in 1.30, was removed.
	* $wgExperimentalHtmlIds – This setting, deprecated since 1.30, was removed.
	The 'html5-legacy' value for $wgFragmentMode is no longer accepted.
	* $wgPasswordSenderName - This setting, ignored since 1.23 by MediaWiki and
	most extensions, is no longer set. Instead, you can modify the system
	message `emailsender`.
	* $wgTidyConfig – The experimental Html5Internal and Html5Depurate tidy drivers
	were removed. RemexHtml, which is the default, should be used instead.
	* (T181318) The $wgStyleVersion setting and its appendage to various script and
	style URLs in OutputPage, deprecated in 1.31, was removed.
	* (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
	from ResourceLoader. Instead, use `@import` statements in LESS to import
	files directly from nearby directories within the same project.
	* (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
	since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
	the ResourceLoaderModule::getLessVars() method.
	* $wgResourceLoaderValidateStaticJS – This setting, unused since MediaWiki 1.18,
	was removed.
	* Two temporary variables for deploying the feature of filters on change lists,
	$wgStructuredChangeFiltersShowPreference introduced in MediaWiki 1.30 and
	$wgStructuredChangeFiltersOnWatchlist in 1.31, were removed.

	=== New features in 1.32 ===
	* (T112474) Generalized the ResourceLoader mechanism for overriding modules
	using a particular page during edit previews.
	* (T12331) You can now log page creation events by setting $wgPageCreationLog
	to true.
	* Added 'ApiParseMakeOutputPage' hook.
	* (T174313) Added checkbox on Special:ListUsers to display only users in
	temporary user groups.
	* (T152462) A cookie can now be set when an IP user is blocked to track that
	user if they move to a new IP address. This is disabled by default.
	* (T194950) Added 'ApiMaxLagInfo' hook.
	* SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
	reauthenticating.
	* FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
	getLoginSecurityLevel() returns non-false.
	* The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
	&$query and &$widthOption, allowing extensions even finer control over the
	resulting HTML code.
	* Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
	if the [mark as patrolled] link should be shown at the footer of patrollable
	pages.
	* The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
	is now passed by reference, allowing extensions to modify or even unset it.
	* Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
	modify the return value of OutputPage#getHeadLinksArray in order to add,
	remove or otherwise alter the elements to be output in the page <head>.
	* (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
	additional links to the subtitle of a history page.
	* The 'GetLinkColours' hook now receives an additional $title parameter,
	the Title object of the page being parsed, on which the links will be shown.
	* (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
	render diffs between two Content objects, and DifferenceEngine::setRevisions()
	to render diffs between two custom (potentially multi-content) revisions.
	Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
	* Added a temporary action=mcrundo to the web UI, as the normal undo logic
	can't yet handle MCR and deadlines are forcing is to put off fixing that.
	This action should be considered deprecated and should not be used directly.
	* Extensions overriding ContentHandler::getUndoContent() will need to be
	updated for the changed method signature.
	* Added a new hook, 'UserGetRightsRemove', which can be used to remove rights
	from user. Unlike the 'UserGetRights' it will ensure that removed rights
	will not be reinserted.
	* (T197535) Extensions can now specify PHP versions and PHP extensions they
	depend on.

	=== Bug fixes in 1.32 ===
	* SpecialPage::execute() will now only call checkLoginSecurityLevel() if
	getLoginSecurityLevel() returns non-false.
	* (T43720, T46197) Improved page display title handling for category pages
	* (T65080) Fixed resetting options of some types via API action=options.

	=== Action API changes in 1.32 ===
	* Added templated parameters.
	* A module can define a templated parameter like "{fruit}-quantity", where
	the actual parameters recognized correspond to the values of a multi-valued
	parameter. Then clients can make requests like
	"fruits=apples\|bananas&apples-quantity=1&bananas-quantity=5".
	* action=paraminfo will return templated parameter definitions separately
	from normal parameters. All parameter definitions now include an "index"
	key to allow clients to maintain parameter ordering when merging normal and
	templated parameters.
	* It is now an error to submit too many values for a multi-valued parameter.
	This has generated a warning since MediaWiki 1.14.
	* Assertion failures from the 'assert' and 'assertuser' parameters will no
	longer use the action module's custom response format, for the few modules
	that use custom formatters that handle errors.
	* (T198935) User list preferences such as `email-blacklist` and similar
	extension preferences are no longer represented as arrays when returned by
	action=query&meta=userinfo&uiprop=options.
	* 'missingparam' errors will now use the prefixed parameter name in the code
	and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
	than "nofoo" and "The 'foo' parameter must be set".
	* action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
	multi-content revision slots for which content should be returned. It also
	has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
	warning will be issued if rvprop=content or rvprop=contentmodel are used
	without rvslots.
	* The rvcontentformat parameter to action=query&prop=revisions has been
	deprecated. Clients should be prepared to deal with the default format for
	relevant models.
	* Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
	rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
	rvprop=parsetree is forbidden with the new 'rvslots' parameter.
	* action=query&prop=deletedrevisions, action=query&list=allrevisions, and
	action=query&list=alldeletedrevisions are changed similarly to
	&prop=revisions (see the three previous items).
	* (T174032) action=compare now supports multi-content revisions.
	* It has a 'slots' parameter to select diffing of individual slots. The
	default behavior is to return one combined diff.
	* The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
	'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
	are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
	slots have text supplied and the corresponding templated parameters for
	each slot.
	* The behavior of 'fromsection' and 'tosection' of extracting one section's
	content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
	instead expand the given text as if for a section edit. This effectively
	declines T183823 in favor of T185723.
	* (T198214) The 'disabletidy' parameter to action=parse has been
	deprecated; untidy output will not be supported by future wikitext
	parsers.
	* Added intestactionsdetail to action=query&prop=info to allow retrieving the
	reasons an action is not allowed.
	* Deprecated action=query&prop=info inprop=readable in favor of
	intestactions=read.
	* (T212356) When using action=delete on pages with many revisions, the module
	may return a boolean-true 'scheduled' and no 'logid'. This signifies that the
	deletion will be processed via the job queue.

	=== Action API internal changes in 1.32 ===
	* Added 'ApiParseMakeOutputPage' hook.
	* Parameter names may no longer contain '{' or '}', as these are now used for
	templated parameters.
	* (T194950) Added 'ApiMaxLagInfo' hook.
	* The following methods now take a RevisionRecord rather than a Revision. No
	external callers are known.
	* ApiFeedContributions::feedItemAuthor()
	* ApiFeedContributions::feedItemDesc()
	* ApiQueryRevisionsBase::extractRevisionInfo()
	* The following deprecated methods have been removed:
	* ApiBase::profileIn() (deprecated in 1.25)
	* ApiBase::profileOut() (deprecated in 1.25)
	* ApiBase::safeProfileOut() (deprecated in 1.25)
	* ApiBase::profileDBIn() (deprecated in 1.25)
	* ApiBase::profileDBOut() (deprecated in 1.25)
	* ApiBase::dieUsage() (deprecated in 1.29)
	* ApiBase::dieUsageMsg() (deprecated in 1.29)
	* ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
	* ApiBase::getErrorFromStatus() (deprecated in 1.29)
	* ApiBase::parseMsg() (deprecated in 1.29)
	* ApiBase::setWarning() (deprecated in 1.29)
	* ApiPageSet::getInvalidTitles() (deprecated in 1.26)
	* ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
	* ApiUsageException::getCodeString() (deprecated in 1.29)
	* ApiUsageException::getMessageArray() (deprecated in 1.29)
	* Class UsageException, deprecated in 1.29, has been removed.
	* ApiErrorFormatter: Added getFormat() and newWithFormat(). In particular, you
	can now easily test $formatter->getFormat() === 'bc', and then call
	$formatter->newWithFormat( 'plaintext' ) to get a non-BC formatter.

	=== Languages updated in 1.32 ===
	MediaWiki supports over 350 languages. Many localisations are updated regularly.
	Below only new and removed languages are listed, as well as changes to languages
	because of Phabricator reports.

	* (T193566) Added language support for Ambonese Malay (abs).

	MediaWiki\Session\Token::SUFFIX instead.
	* EditPage::isOouiEnabled() deprecated in 1.30, was removed.
	* mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl()
	instead.
	* (T61113) The following methods and constants from the Revision class, which
	were deprecated in 1.25, have now been removed:
	* Revision::getRawUser()
	* Revision::getRawUserText()
	* Revision::getRawComment()
	* window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use
	mw.msg() or mw.message() instead.
	* mw.util.escapeId(), deprecated in 1.30, was removed. Use
	mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
	* mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
	jquery.accessKeyLabel instead.
	* The SqlDataUpdate class, deprecated in 1.28, has been removed.
	* The Html5Internal and Html5Depurate tidy driver classes were removed, along
	with the Balancer tidy implementation. Both implementations were experimental,
	and were replaced by RemexHtml.
	* (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
	removed. Use JobQueueGroup::singleton()->push() instead.
	* The jquery.footHovzer module, for mediawiki.debug, was removed.
	* The es5-shim module, empty and deprecated since 1.29, was removed.
	* the dom-level2-shim module, empty and deprecated since 1.29, was removed.
	* the json module, empty and deprecated since 1.29, was removed.
	* The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was
	removed. Use mediawiki.widgets.visibleLengthLimit instead.
	* The jquery.farbtastic module, unused since 1.18, was removed.
	* The 'jquery.expandableField' module, unused since 1.22, was removed.
	* The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
	any HTMLForm object rather than PreferencesForm.
	* The non namespaced TimestampException class, deprecated in 1.29, was removed.
	Use Wikimedia\Timestamp\TimestampException instead.
	* The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
	utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
	The UtfNormal\Utils class from the utfnormal library should be used instead.
	* The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
	from the UtfNormal\Constants class from the utfnormal library should be used
	* The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
	only needed for PHP5 compatibility, have been removed. It now uses the boolean
	values `true` and `false` respectively.
	* The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
	were removed. Use the ParserCache class instead.
	* ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
	instead.
	* Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
	deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
	* (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
	and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
	is no longer loaded by default. The Vector and MonoBook skins have made a
	minor change to implement the toggle feature with CSS instead. To restore
	prior functionality, either explicitly load "jquery.mw-jump" in your skin
	or refer to T195256 for details on how to make the same change.
	* Hook 'EditPageBeforeEditChecks' was removed;
	use 'EditPageGetCheckboxesDefinition' instead.
	* Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
	1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
	* Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
	been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
	instead.
	* mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
	CapsuleMultiselectWidget. The following methods may no longer be used:
	* setItemsFromData: Use setValue instead
	* getItemsData: Use getItems instead and get the data property
	* Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
	removed. Use addLink() instead.
	* Another two OutputPage methods, setPageTitleActionText() and
	getPageTitleActionText(), were removed. They did nothing since 1.15 (almost
	ten years). Use setHTMLTitle() directly.
	* The return value of OutputPage::adaptCdnTTL() has been removed. The
	value returned was misleading and probably not what any caller would
	have wanted.
	* All MagicWord static member variables have been removed. Use appropriate
	hooks or MagicWordFactory methods instead.
	* MagicWord::clearCache() has been removed. Instead, create a new
	MagicWordFactory, such as by calling
	resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
	* mw.util.init() has been removed. This function is not needed anymore and was
	a no-op function since 1.30.
	* SpecialPageFactory::resetList() is a no-op. Call overrideMwServices()
	instead.
	* MediaWiki no longer supports a StartProfiler.php file. Instead, you can set
	$wgProfiler and $wgEnableProfileInfo.
	* The mw.loader.addSource() is now considered a private method, and no longer
	supports the `id, url` signature. Use the `Object` parameter instead.
	* The backwards-compatibility code in HTMLForm to add a drop-down control to an
	option that is not set to be a drop-down if the "mw-chosen" class is present,
	is now removed.
	* Several collations were removed. They were workarounds for bugs in the ICU
	library and they are no longer needed (as of ICU 57.1):
	* 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
	* 'xx-uca-et' (CollationEt) - use 'uca-et' instead
	* 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
	* LanguageCode::bcp47() now always returns a valid BCP 47 code. This means
	that some MediaWiki-specific language codes, such as `simple`, are mapped
	into valid BCP 47 codes (eg `en-simple`).
	* The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated
	in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'.
	The ChangesListSpecialPage code for these legacy hooks, and their use in
	SpecialRecentchanges.php and SpecialWatchlist, was also removed:
	* ChangesListSpecialPage->getCustomFilters()
	* ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters()
	* ChangesListSpecialPage::customFilters
	* The global function wfUseMW, deprecated since 1.26, has now been removed. Use
	the "requires" property of static extension registration instead.
	* $wgSpecialPages no longer accepts array syntax, deprecated since 1.18.
	* The MailAddress constructor can no longer be called with a User object,
	behaviour which has been deprecated since 1.24.
	* LBFactory, deprecated since 1.28, has been removed. Instead, use
	Wikimedia\Rdbms\LBFactory.
	* The MimeMagic class, deprecated since 1.28 has been removed. Get a
	MimeAnalyzer instance from MediaWikiServices instead.
	* The '--tidy' option to maintenance/parse.php has been removed. Tidying
	the output is now the default. Use '--no-tidy' to bypass the tidy
	phase.
	* The global function wfErrorLog, deprecated since 1.25, has now been removed.
	Use MWLoggerLegacyLogger::emit or UDPTransport.
	* The hooks 'SpecialRecentChangesQuery' & 'SpecialWatchlistQuery', deprecated in
	1.23, were removed. Instead, use ChangesListSpecialPageStructuredFilters or
	ChangesListSpecialPageQuery.
	* The global function wfUsePHP, deprecated since 1.30, has now been removed. To
	assert a newer version of PHP than MediaWiki does, use extension registration.
	* The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been
	removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
	* DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
	* File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
	* The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use
	the hook 'SkinEditSectionLinks' instead.
	* The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.
	* The global function wfRunHooks, deprecated since 1.25, has now been removed.
	Use Hooks::run().
	* The hook 'UnknownAction', deprecated since 1.19, has now been removed.
	* The hook 'ParserLimitReport', deprecated since 1.22, has been removed. Use
	the hooks 'ParserLimitReportPrepare' and 'ParserLimitReportFormat' instead.
	* The following deprecated API methods have been removed:
	* ApiBase::profileIn() (deprecated in 1.25)
	* ApiBase::profileOut() (deprecated in 1.25)
	* ApiBase::safeProfileOut() (deprecated in 1.25)
	* ApiBase::profileDBIn() (deprecated in 1.25)
	* ApiBase::profileDBOut() (deprecated in 1.25)
	* ApiBase::dieUsage() (deprecated in 1.29)
	* ApiBase::dieUsageMsg() (deprecated in 1.29)
	* ApiBase::dieUsageMsgOrDebug() (deprecated in 1.29)
	* ApiBase::getErrorFromStatus() (deprecated in 1.29)
	* ApiBase::parseMsg() (deprecated in 1.29)
	* ApiBase::setWarning() (deprecated in 1.29)
	* ApiPageSet::getInvalidTitles() (deprecated in 1.26)
	* ApiQueryLogEvents::addLogParams() (deprecated in 1.25)
	* ApiUsageException::getCodeString() (deprecated in 1.29)
	* ApiUsageException::getMessageArray() (deprecated in 1.29)
	* Class UsageException, deprecated in 1.29, has been removed.
	* MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The
	old "bulletin board style toolbar", known as "the 2006 wikitext editor", has
	been removed, and instead sysadmins will be required to choose one (or more)
	of the several extensions available for this purpose if they need the
	functionality. The MediaWiki "tarball" releases have included the replacement
	extension for this, the WikiEditor extension aka "the 2010 wikitext editor",
	for many years now. As part of this, several parts of MediaWiki have been
	removed or simplified:
	* The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer
	available; if an extension adds a toolbar via the EditPageBeforeEditToolbar
	hook, it will be shown; extensions should provide a specific user preference
	to disable themselves as needed.
	* The public methods Language::getImageFile() and ::getImageFiles(), and the
	related specification of $imageFiles within individual languages' code file,
	as well as the referenced static media assets, all of which were only used
	inside MediaWiki itself for providing the icons for the old toolbar, have
	been removed without explicit deprecation.
	* The internal ResourceLoader module "mediawiki.toolbar", which is unused
	except by MediaWiki itself and back-compatibility code, has been removed.
	* The internal ResourceLoaderEditToolbarModule class has been removed.

	=== Deprecations in 1.32 ===
	* HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
	button is already marked as progressive.
	* Skin::setupSkinUserCss() is deprecated. Adding of modules to load
	has been centralised to Skin::getDefaultModules(), which is now capable
	of queueing style modules as well.
	* OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
	deprecated. Use addModules() instead.
	* Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
	in extending classes is deprecated. Extend related doSearch* methods
	instead.
	* The following 'mediawiki.api' plugin modules were merged into mediawiki.api
	and deprecated: mediawiki.api.category, mediawiki.api.edit,
	mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
	mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
	mediawiki.api.messages, and mediawiki.api.rollback.
	* ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
	to use it.
	* WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
	with the 'unwatch' action parameter instead.
	* IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
	constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
	* Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
	* The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
	* The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
	of the namespaced classes provided by the wikimedia/xmp-reader library.
	* SearchResultSet::{next,rewind} are deprecated. Calling code should
	use foreach on the SearchResultSet, or the extractResults method. Extending
	code should override extractResults.
	* Instantiating SearchResultSet directly is deprecated. SearchEngine
	implementations must subclass SearchResultSet for their purposes.
	* SearchResult::setExtensionData argument has been changed from accepting an
	array to accepting a Closure that returns the array when called.
	* Class CryptRand, everything in MWCryptRand except generateHex() and function
	MediaWikiServices::getInstance()->getCryptRand() are deprecated, use
	random_bytes() to generate cryptographically secure random byte sequences.
	* Parser::getConverterLanguage() is deprecated. Use ::getTargetLanguage()
	instead.
	* Language::markNoConversion() is deprecated. It confused readers because
	it had unexpected behavior (only marking text if it looked like a URL)
	and was only used in a single place in the code. Use
	LanguageConverter::markNoConversion() instead.
	* (T197492) Language::truncate() was soft deprecated in 1.31 and is
	hard deprecated in this release. It has been split into two similar
	methods, Language::truncateForVisual() and Language::truncateForDatabase(),
	which measure length in characters and bytes, respectively. Use
	Language::truncateForVisual() when possible to provide equity to users
	of multibyte scripts.
	* (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
	context title is unset is now deprecated; anything creating an EditPage
	instance should set the context title via ::setContextTitle().
	* The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
	* ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
	are deprecated. These concepts are obsolete and have no replacement.
	* String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
	* The following methods of OutputPage are now deprecated in favour
	of using showFatalError directly: OutputPage::showFileDeleteError()
	OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
	OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
	* The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
	classes are now deprecated. Use a Closure instead.
	* (T194263) ContentHandler::makeParserOptions() is deprecated. Use
	WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
	* (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
	MediaWiki 1.26, is now hard-deprecated. All known clients were converted to
	the Parsoid v3 API in May 2015.
	* $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
	$formDescriptor instead.
	* SearchEngine::transformSearchTerm( $term ) should no longer be called prior
	to running searchText. This method was mainly implemented to support the
	'prefix' URI param in SpecialSearch, but there are no reasons to expose this
	logic as it should be handled internally by SearchEngine implementations
	supporting this feature. SearchEngine implementations should no longer
	override this methods.
	* SearchEngine::replacePrefixes( $query ) should no longer be called prior
	to running searchText/searchTitle.
	* (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
	'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
	* Global functions wfArrayFilter() and wfArrayFilterByKey() are deprecated.
	use array_filter() directly.
	* The $wgShowSQLErrors global is deprecated and nonfunctional.
	Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
	* The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
	Set $wgShowExceptionDetails instead.
	* Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
	mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
	mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
	getOldRevision() / getNewRevision() for the first four (note that the
	revision ones return a RevisionRecord, not a Revision), do your own lookup
	for page/content.
	* The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
	just enable the PHP extension, and it will be autodetected.
	* (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
	setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
	are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
	subclass it to customize diff rendering); to diff custom (e.g. unsaved)
	content, use setRevisions(). Subclassing DifferenceEngine should only be done
	to customize page-level diff properties (such as the navigation header).
	* The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
	* All MagicWord static methods are now deprecated. Use the MagicWordFactory
	methods instead.
	* PasswordFactory::init is deprecated. To get a password factory with the
	standard configuration, use
	MediaWikiServices::getInstance()->getPasswordFactory.
	* $wgContLang is deprecated, use
	MediaWikiServices::getInstance()->getContentLanguage() instead.
	* $wgParser is deprecated, use MediaWikiServices::getInstance()->getParser()
	instead.
	* wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
	instead.
	* wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
	* All SpecialPageFactory static methods are deprecated. Instead, call the
	methods on a SpecialPageFactory instance, which may be obtained from
	MediaWikiServices.
	* mw.user.stickyRandomId was renamed to the more explicit
	mw.user.getPageviewToken to better capture its function.
	* Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
	Content object should be passed instead.
	* (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
	previously used by OOUI HTMLForm fields, are now deprecated. Use
	'help', 'help-message', 'help-messages' instead.
	* (T197179) HTMLFormField::getNotices() is now deprecated.
	* The jquery.localize module is now deprecated. Use jquery.i18n instead.
	* The SecondaryDataUpdates hook was deprecated in favor of RevisionDataUpdates,
	or overriding ContentHandler::getSecondaryDataUpdates (T194038).
	* The WikiPageDeletionUpdates hook was deprecated in favor of
	PageDeletionDataUpdates, or overriding ContentHandler::getDeletionDataUpdates
	(T194038).
	* Content::getSecondaryDataUpdates has been deprecated in favor of
	ContentHandler::getSecondaryDataUpdates() for overriding by extensions
	(T194038).
	Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
	* Content::getDeletionUpdates has been deprecated in favor of
	ContentHandler::getDeletionUpdates() for overriding by extensions (T194038).
	Application logic should call WikiPage::doSecondaryDataUpdates() (T194037).
	* (T198214) Old Tidy-related configuration settings, which were soft-deprecated
	in MediaWiki 1.26, have now been hard deprecated. This affects $wgUseTidy,
	$wgTidyBin, $wgTidyConf, $wgTidyOpts, $wgTidyInternal, and $wgDebugTidy. Use
	$wgTidyConfig instead.
	* All Tidy configurations other than Remex have been hard deprecated;
	future parsers will not emit compatible output for these configurations.
	In particular, running MediaWiki with tidy disabled has been deprecated.
	* (T198214) OutputPage::addWikiText(), OutputPage::addWikiTextWithTitle(),
	and OutputPage::addWikiTextTitle() have been deprecated, since they
	can result in untidy output. In addition OutputPage::addWikiTextTidy()
	and OutputPage::addWikiTextTitleTidy() was deprecated to make naming new
	methods consistent. Use OutputPage::addWikiTextAsInterface() or
	OutputPage::addWikiTextAsContent() instead, which ensures the output is
	tidy and clarifies whether content-language specific postprocessing should
	be done on the text.
	* OutputPage::parse() and OutputPage::parseInline() have been deprecated
	due to untidy output and inconsistent handling of wrapper divs and
	interface/content language defaults. Use OutputPage::parseAsContent(),
	OutputPage::parseAsInterface(), or OutputPage::parseInlineAsInterface()
	as appropriate.
	* QuickTemplate::msgHtml() and BaseTemplate::msgHtml() have been deprecated
	as they promote bad practises. I18n messages should always be properly
	escaped.
	* Skin::getDynamicStylesheetQuery() has been deprecated. It always
	returns action=raw&ctype=text/css which callers should use directly.
	* Class LegacyFormatter is deprecated.
	* Use of CommentStore::insertWithTempTable() with 'img_description' is
	deprecated. Use CommentStore::insert() instead.
	* Language::setCode is deprecated as public function. Use Language::factory
	to create a new Language object with a different language code.
	* Several classes have been moved from the MediaWiki\Storage\ namespace to the
	MediaWiki\Revision\ namespace. The old class names are aliased for
	compatibility, but are deprecated. Classes are IncompleteRevisionException,
	MutableRevisionRecord, MutableRevisionSlots, RevisionAccessException,
	RevisionArchiveRecord, RevisionFactory, RevisionLookup, RevisionRecord,
	RevisionSlots, RevisionStore, RevisionStoreRecord, SlotRecord, and
	SuppressedDataException.
	* When using OOUI HTMLForm containing an 'info' field which uses the 'rawrow'
	option, it is now deprecated to give its contents (the 'default' option)
	as a string. They should be given as a OOUI\FieldLayout object instead.
	Notably, this affects fields defined in the 'GetPreferences' hook, because
	Special:Preferences uses an OOUI form now. (If possible, don't use 'rawrow'.)
	* In Skin::doEditSectionLink omitting the parameters $tooltip and $lang is
	deprecated. For the $lang parameter, types other than Language are
	deprecated.
	* The $wgUseKeyHeader configuration option and the
	OutputPage::getKeyHeader() method have been deprecated; the relevant
	draft IETF spec expired without becoming a standard.
	* Deprecated API action=query&prop=info inprop=readable in favor of
	intestactions=read.

	=== Other changes in 1.32 ===
	* (T198811) The following tables have had their UNIQUE indexes turned into
	proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
	protected_titles and site_identifiers.
	* OOUI HTMLForm will now display help text inline after the input field,
	rather than in a popup. Previous behavior can be restored by using
	`'help-inline' => false`.
	* The archive table's ar_rev_id field is now unique.
	* Special:BotPasswords now requires reauthentication.
	* (T174023) Multi-Content Revision (MCR) capabilities were introduced into the
	storage layer and have basic support for display. No user interface exists
	yet for creating or managing content in slots beides the main slot. See
	<https://www.mediawiki.org/wiki/Multi-Content_Revisions> for more
	information.
	* The image_comment_temp database table has been removed. Since all access
	should be mediated by the CommentStore class, this change shouldn't affect
	external code.
	* (T206147) Database::close() will no longer commit any open transactions.
	* (T64103) Dropped columns category.cat_hidden, site_stats.ss_admins, and
	recentchanges.rc_cur_time from the PostgreSQL schema.

	* (T195783) Initialize PSR-4 namespaces at same stage as normal autoloader.
	* (T196092) Hide MySQL binary/utf-8 charset option in the installer.

	=== Important pre-upgrade notes for 1.31 ===
	* If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
	schema changes, and cannot have downtime to run migrateArchiveText.php and
	apply patch-drop-ar_text.sql manually, you'll have to apply a default value
	to the ar_text and ar_flags columns of the archive table or make those
	columns nullable before upgrading to MediaWiki 1.31.
	maintenance/archives/patch-nullable-ar_text.sql shows how to do this for
	MySQL.

	=== Configuration changes in 1.31 ===
	* $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
	a future version. The API is now considered to be stable, secure and
	essential.
	* $wgUsejQueryThree was removed, as it is now the default. This was documented
	as a temporary variable during the migration period, deprecated since 1.29.
	* $wgLogoHD has been updated to support svg images and uses $wgLogo where
	possible for fallback images such as png.
	* (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
	have the right to mark things patrolled.
	* Wikis that contain imported revisions or CentralAuth global blocks should run
	maintenance/cleanupUsersWithNoId.php.
	* The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
	$wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
	* (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
	are not using the latest version of the Referrer Policy specification.
	* $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
	first step of migration to human-readable section IDs that will later result
	in 'html5' being the default mode.
	* CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
	as upstream is inactive and has no plans to move to PHP 7.
	* The old CategorizedRecentChanges feature, including its related configuration
	option $wgAllowCategorizedRecentChanges, has been removed.
	* (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
	for performance reasons, and installations with this setting will now work as
	if it was configured with 'any'.
	* (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
	rather than being off by default. If you wish to disable HTML tidying
	entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
	Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
	* $wgLogAutopatrol now defaults to false instead of true.
	* $wgValidateAllHtml was removed and will be ignored.
	* $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
	1.25 release notes for more information.
	* $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
	framework that it enables. Some extensions mistakenly used this to check
	whether any AJAX functionality at all should be enabled, further making this
	problematic to retain.
	* $wgDBmysql5 is now deprecated, and will be removed in a future version. It
	has been marked as experimental ever since it was introduced.

	=== New features in 1.31 ===
	* (T76554) User sub-pages named ….json are now protected in the same way that
	….js and ….css pages are, so that configuration options can safely be placed
	there.
	* Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
	with parentheses for grouping.
	* As a first pass in standardizing dialog boxes across the MediaWiki product,
	Html class now provides helper methods for messageBox, successBox, errorBox
	and warningBox generation.
	* (T9240) Imports will now record unknown (and, optionally, known) usernames in
	a format like "iw>Example".
	* (T20209) Linker (used on history pages, log pages, and so on) will display
	usernames formed like "iw>Example" as interwiki links, as if by wikitext like
	[[iw:User:Example\|iw>Example]].
	* (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
	users during an import.
	* Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
	the ParserOutput::getText() post-cache transformations.
	* Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
	initial page text for file uploads.
	* (T181651) The info page for File pages now displays the file's base-16 SHA1
	hash value in the table of basic information.
	* Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
	ParserOutput::getText() post-cache transformation. This may be disabled by
	passing 'deduplicateStyles' => false to that method.
	* The identity of the logged-in or IP "actor" for logged actions is being moved
	into a new actor table, with the rows in tables such as revision and logging
	referring to the actor ID instead of storing the user ID and name/IP in
	every row.
	* This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
	can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
	soon as any necessary extensions are updated.
	* Most code accessing rows for logged actions from the database should use
	the relevant getQueryInfo() methods to get the information needed to build
	the SQL query. The ActorMigration class may also be used to get feature
	-flagged information needed to access actor-related fields during the
	migration period.
	* Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
	section without having to roll back the whole transaction.
	* Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
	and non-MySQL ::replace() and ::upsert() no longer roll back the whole
	transaction on failure.
	* (T189785) Added a monthly heartbeat ping to the pingback feature.
	* The CLI installer (maintenance/install.php) learned to detect and include
	extensions. Pass --with-extensions to enable that feature.
	* (T184791) rc_patrolled now has three states: "0" for unpatrolled,
	"1" for manually patrolled and "2" for autopatrolled actions.
	* Extensions can now set their type to "editor" if they provide an editor or
	enhance the editing experience.
	* Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
	property in extension.json. See the documentation at
	<https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
	for more details and an example.
	* (T19099) Tabs which link to pages that don't exist (like those to uncreated
	discussion pages) now have a tooltip to indicate state, not just colour.

	=== External library changes in 1.31 ===
	* pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
	suggested to required. These packages now must be installed via composer
	and not via PEAR itself.

	returned regardless.

	* User::selectFields() → User::getQueryInfo()
	* WikiPage::selectFields() → WikiPage::getQueryInfo()
	* Revision::setUserIdAndName() was deprecated.
	* Access to TitleValue class properties was deprecated, the relevant getters
	should be used instead.
	* DifferenceEngine::getDiffBodyCacheKey() is deprecated. Subclasses should
	override DifferenceEngine::getDiffBodyCacheKeyParams() instead.

	Maintenance::fatalError() instead.
	* Passing a ParserOptions object to OutputPage::parserOptions() is deprecated.

	* ParserOutput::setTOCEnabled()
	* OutputPage::enableSectionEditLinks()
	* OutputPage::sectionEditLinksEnabled()
	* The public ParserOutput state fields $mTOCEnabled and $mEditSectionTokens
	are also deprecated.
	* License::getLicenses has been deprecated; use License::getLines instead.
	* QuickTemplate::setRef() was deprecated in favour of QuickTemplate::set().
	Setting template variables by reference allowed violating the principle of
	data being immutable once added to the skin template. In practice, this method
	was not being used for that. Rather, setRef() existed as memory optimisation
	for PHP 4.
	* QuickTemplate::setTranslator() and MediaWikiI18N::set() were deprecated in
	favour of Skin::msg() parameters.
	* MediaWikiI18N::translate() was deprecated in favour of Skin::msg() or
	wfMessage().
	* Passing false to ParserOptions::setWrapOutputClass() is deprecated. Use the
	'unwrap' transform to ParserOutput::getText() instead.
	* \ObjectFactory (no namespace) is deprecated, the namespaced class
	\Wikimedia\ObjectFactory from the wikimedia/object-factory library should be
	used instead.
	* CommentStore::newKey is deprecated. Instead, get an instance from
	MediaWikiServices.
	* The following CommentStore methods have had their signatures changed to
	introduce a $key parameter, usage of the methods on instances retrieved from
	CommentStore::newKey will remain unchanged but deprecated:
	* CommentStore::getFields
	* CommentStore::getJoin
	* CommentStore::getComment
	* CommentStore::getCommentLegacy
	* CommentStore::insert
	* CommentStore::insertWithTemplate
	* The following methods in Title have been renamed, and the old ones are
	deprecated:
	* Title::getSkinFromCssJsSubpage – use ::getSkinFromConfigSubpage
	* Title::isCssOrJsPage – use ::isSiteConfigPage
	* Title::isCssJsSubpage – use ::isUserConfigPage
	* Title::isCssSubpage – use ::isUserCssConfigPage
	* Title::isJsSubpage – use ::isUserJsConfigPage
	* The following methods related to caching of half-parsed HTML were deprecated:
	* Parser::serializeHalfParsedText()
	* Parser::unserializeHalfParsedText()
	* Parser::isValidHalfParsedText()
	* StripState::getSubState()
	* StripState::merge()
	* The DeferredStringifier class is deprecated, use Message::listParam() instead.
	* The type string for the parameter $lang of DateFormatter::getInstance is
	deprecated.
	* Wikimedia\Rdbms\SavepointPostgres is deprecated.
	* The DO_MAINTENANCE constant is deprecated. RUN_MAINTENANCE_IF_MAIN should be
	used instead.
	* The function wfShellWikiCmd() has been deprecated, use
	MediaWiki\Shell::makeScriptCommand().
	* In the future, the hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend'
	will be allowed to provide any HTMLForm object rather than PreferencesForm.

	=== Other changes in 1.31 ===
	* Browser support for Internet Explorer 10 was lowered from Grade A to Grade C.
	* Browser support for Opera 12 and older was dropped entirely. Opera 15+
	continues at Grade A.
	* Multi-content-revision capability was introduced into the storage layer. See
	<https://mediawiki.org/wiki/Requests_for_comment/Multi-Content_Revisions>.
	* The "free" CSS class is now only applied to unbracketed URLs in wikitext.
	Links written using square brackets will get the class "text" not "free".
	* RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
	wikitext table captions, wikitext table headings, wikitext table cells. HTML
	headings, HTML list items, HTML table captions, HTML table headings, HTML
	table cells will not have this trimming behavior.

	== Compatibility ==
	MediaWiki 1.31 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
	supported, it is generally advised to use PHP 7.0.0 or later for long term
	support.

	MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
	but support for them is somewhat less mature. There is experimental support for
	Oracle and Microsoft SQL Server.

	The supported versions are:

	* MySQL 5.5.8 or later
	* PostgreSQL 9.2 or later
	* SQLite 3.3.7 or later
	* Oracle 9.0.1 or later
	* Microsoft SQL Server 2005 (9.00.1399)

	== Upgrading ==
	1.31 has several database changes since 1.30, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions, including
	important information when upgrading from versions prior to 1.11.

	For notes on 1.30.x and older releases, see HISTORY.

	== Online documentation ==
	Documentation for both end-users and site administrators is available on
	MediaWiki.org, and is covered under the GNU Free Documentation License (except
	for pages that explicitly state that their contents are in the public domain):

	https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation

	== Mailing list ==
	A mailing list is available for MediaWiki user support and discussion:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

	A low-traffic announcements-only list is also available:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

	It's highly recommended that you sign up for one of these lists if you're
	going to run a public MediaWiki, so you can be notified of security fixes.

	== IRC help ==
	There's usually someone online in #mediawiki on irc.freenode.net.

	=== MySQL version requirement in 1.30 ===
	As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
	section).

	=== Configuration changes in 1.30 ===
	* The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
	unexpected behavior when code uses locale-sensitive string comparisons. For
	example, the Scribunto extension considers "bar" < "Foo" in most locales
	since it ignores case.
	* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
	documentation of $wgShellLocale for details.
	* $wgShellLocale is now applied for all requests. wfInitShellLocale() is
	deprecated and a no-op, as it is no longer needed.
	* $wgJobClasses may now specify callback functions as an alternative to plain
	class names. This is intended for extensions that want control over the
	instantiation of their jobs, to allow for proper dependency injection.
	* $wgResourceModules may now specify callback functions as an alternative
	to plain class names, using the 'factory' key in the module description
	array. This allows dependency injection to be used for ResourceLoader modules.
	* $wgExceptionHooks has been removed.
	* (T163562) $wgRangeContributionsCIDRLimit was introduced to control the size
	of IP ranges that can be queried at Special:Contributions.
	* (T45547) $wgUsePigLatinVariant added (off by default).
	* (T152540) MediaWiki now supports a section ID escaping style that allows to
	display non-Latin characters verbatim on many modern browsers. This is
	controlled by the new configuration setting, $wgFragmentMode.
	* $wgExperimentalHtmlIds is now deprecated and will be removed in a future
	version, use $wgFragmentMode to migrate off it to a modern alternative.
	* $wgExternalInterwikiFragmentMode was introduced to control how fragments in
	sinterwikis going outside of current wiki farm are encoded.
	* (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of
	'mysqli'. This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0.
	MediaWiki auto-selects the 'mysqli' driver since MediaWiki 1.22, except if
	explicitly requested through the configuration parameter $wgDBservers.
	* $wgOOUIEditPage was removed, as it is now the default. This was documented as
	a temporary variable during the migration period.

	=== New features in 1.30 ===
	* (T37247) Output from Parser::parse() will now be wrapped in a div with
	class="mw-parser-output" by default. This may be changed or disabled using
	ParserOptions::setWrapOutputClass().
	* (T163562) Added ability to search for contributions within an IP ranges
	at Special:Contributions.
	* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
	specific tags to be added by users.
	* Added a 'ParserOptionsRegister' hook to allow extensions to register
	additional parser options.
	* (T45547) Included Pig Latin, a language game in English, as a
	LanguageConverter variant. This allows English-speaking developers
	to develop and test LanguageConverter more easily. Pig Latin can be
	enabled by setting $wgUsePigLatinVariant to true.
	* Added RecentChangesPurgeRows hook to allow extensions to purge data that
	depends on the recentchanges table.
	* Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
	* (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
	'watchlistunwatchlinks' preference option is enabled). With JavaScript
	enabled, these links toggle so the user can also re-watch pages that have
	just been unwatched.
	* Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
	MediaHandlerFactory for parser tests.
	* Edit summaries, block reasons, and other "comments" are now stored in a
	separate database table. Use the CommentFormatter class to access them.
	** This is currently gated by $wgCommentTableSchemaMigrationStage. Most wikis
	can set this to MIGRATION_NEW and run maintenance/migrateComments.php as
	soon as any necessary extensions are updated.
	* (T138166) Added ability for users to prohibit other users from sending them
	emails with Special:Emailuser. Can be enabled by setting
	$wgEnableUserEmailBlacklist to true.
	* (T67297) $wgBrowserBlacklist is deprecated, and changing it will have no
	effect. Instead, users using browsers that do not support Unicode will be
	unable to edit and should upgrade to a modern browser instead.

	=== External library changes in 1.30 ===

	==== Upgraded external libraries ====
	* Updated justinrainbow/json-schema from v3.0 to v5.2.

	* When errorformat is not 'bc', abort reasons from action=login will be
	formatted as specified by the error formatter parameters.
	* action=compare can now handle arbitrary text, deleted revisions, and
	returning users and edit comments.
	* (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
	'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
	parameters to prop=revisions are deprecated, as are the similarly named
	parameters to prop=deletedrevisions, list=allrevisions, and
	list=alldeletedrevisions. Use action=compare, action=parse, or
	action=expandtemplates instead.

	=== Action API internal changes in 1.30 ===
	* ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
	deprecated. The existing message should be split between "apihelp-*-summary"
	and "apihelp-*-extended-description".
	* (T123931) Individual values of multi-valued parameters can now be marked as
	deprecated.

	=== Languages updated in 1.30 ===
	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Phabricator reports.

	* Added: kbp (Kabɩyɛ / Kabiyè)
	* Added: skr (Saraiki, سرائیکی)
	* Added: tay (Tayal / Atayal)
	* Removed: tokipona (Toki Pona)

	==== Pig Latin added ====
	* (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
	for easier variant development and testing. Disabled by default. It can be
	enabled by setting $wgUsePigLatinVariant to true.

	=== Other changes in 1.30 ===
	* The use of an associative array for $wgProxyList, where the IP address is in
	the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
	Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
	* mw.user.bucket (deprecated in 1.23) was removed.

	BagOStuff::makeGlobalKey() should be used instead.
	* (T146304) Preprocessor handling of LanguageConverter markup has been improved.
	As a result of the new uniform handling, '-{' may need to be escaped
	(for example, as '-<nowiki/>{') where it occurs inside template arguments
	or wikilinks.
	* (T163966) Page moves are now counted as edits for the purposes of
	autopromotion, i.e., they increment the user_editcount field in the database.
	* Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
	manipulating Special:Log and Special:NewPages lines.
	* The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
	PageHistoryLineEnding, ContributionsLineEnding and
	DeletedContributionsLineEnding hooks have an additional parameter, for
	manipulating HTML data attributes of RC/history lines.
	EnhancedChangesListModifyBlockLineData can do that via the
	$data['attribs'] subarray.
	* (T130632) The OutputPage::enableTOC() method was removed.
	* WikiPage::getParserOutput() will now throw an exception if passed
	ParserOptions that would pollute the parser cache. Callers should use
	WikiPage::makeParserOptions() to create the ParserOptions object and only
	change options that affect the parser cache key.
	* Article::viewRedirect() is deprecated.
	* IP::isValidBlock() was deprecated. Use the equivalent IP::isValidRange().
	* DeprecatedGlobal no longer supports passing in a direct value, it requires a
	callable factory function or a class name.
	* The $parserMemc global, wfGetParserCacheStorage(), and
	ParserCache::singleton() are all deprecated. The main ParserCache instance
	should be obtained from MediaWikiServices instead. Access to the underlying
	BagOStuff is possible through the new ParserCache::getCacheStorage() method.
	* .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
	* Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
	escapeIdForLink() or escapeIdForExternalInterwiki() instead.

	Sanitizer functions or, if possible, Title::getFragmentForURL().
	* Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
	nothing and is deprecated.
	* mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
	escapeIdForLink().
	* MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
	* WikiImporter now requires the second parameter to be an instance of the
	Config, class. Prior to that, the Config parameter was optional (a behavior

	should be avoided and will be deprecated in a future release.
	* EditPage::safeUnicodeInput() and ::safeUnicodeOutput() are deprecated and
	no-ops.
	* EditPage::$isCssJsSubpage, ::$isCssSubpage, and ::$isJsSubpage are
	deprecated. The corresponding methods from Title should be used instead.
	* EditPage::$isWrongCaseCssJsPage is deprecated. There is no replacement.
	* EditPage::$mArticle and ::$mTitle are deprecated for public usage. The
	getters ::getArticle() and ::getTitle() should be used instead.
	* Trying to control or fake EditPage context by overriding $wgUser,
	$wgRequest, $wgOut, and $wgLang is no longer supported and won't work. The

	* Parser::getRandomString() (deprecated in 1.26) was removed.
	* Parser::uniqPrefix() (deprecated in 1.26) was removed.
	* Parser::extractTagsAndParams() now only accepts three arguments. The fourth,

	=== Changes since 1.29.1 ===
	* (T164999) Define mw.Upload.Dialog.static.name in mediawiki.Upload.Dialog.js.
	* (T172061) Fix fatal when passing a category to refreshLinks.php.

	== MediaWiki 1.29.0 ==

	=== Configuration changes in 1.29 ===
	* Default cookie expiration time has been reduced to 30 days. Login cookie
	expiration time is kept at 180 days.
	* A new configuration variable has been added: $wgCookieSetOnAutoblock. This
	determines whether to set a cookie when a user is autoblocked. Doing so means
	that a blocked user, even after logging out and moving to a new IP address,
	will still be blocked.
	* The resetpassword right and associated password reset capture feature has
	been removed.
	* The $error parameter to the EmailUser hook should be set to a Status object
	or boolean false. This should be compatible with at least MediaWiki 1.23 if
	not earlier. Returning a raw HTML string is now deprecated.
	* The $message parameter to the ApiCheckCanExecute hook should be set to an
	ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
	code for ApiBase::parseMsg() will no longer work.
	* ApiBase::$messageMap is no longer public. Code attempting to access it will
	result in a PHP fatal error.
	* $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC
	policies.
	* Subpages are now enabled by default in the Template namespace. Set
	$wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
	* $wgRunJobsAsync is now false by default (T142751). This change only affects
	wikis with $wgJobRunRate > 0.
	* (T158474) "Unknown user" has been added to $wgReservedUsernames.
	* (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single
	IPs.
	* $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
	added to $wgExtraLanguageCodes instead.
	* (T161453) LocalisationCache will no longer use the temporary directory in it's
	fallback chain when trying to work out where to write the cache.
	* The user right 'editusercssjs' (deprecated in 1.16) was removed. Use
	'editusercss' and 'edituserjs' in $wgGroupPermissions and elsewhere instead.

	=== New features in 1.29 ===
	* (T5233) A cookie can now be set when a user is autoblocked, to track that user
	if they move to a new IP address. This is disabled by default.
	* Added ILocalizedException interface to standardize the use of localized
	exceptions, largely so the API can handle them more sensibly.
	* Blocks created automatically by MediaWiki, such as for configured proxies or
	dnsbls, are now indicated as such and use a new i18n message when displayed.
	* Added new $wgHTTPImportTimeout setting. Sets timeout for
	downloading the XML dump during a transwiki import in seconds.
	* Parser limit report is now available in machine-readable format to JavaScript
	via mw.config.get('wgPageParseReport').
	* Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
	from certain IP ranges (e.g. private IPs).
	* (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
	of the page being parsed.
	* HTML5 form validation attributes will no longer be suppressed. Originally
	browsers had poor support for them, but modern browsers handle them fine.
	This might affect some forms that used them and only worked because the
	attributes were not actually being set.
	* Expiry times can now be specified when users are added to user groups.
	* Completely new user interface for the RecentChanges page, which
	structures filters into user-friendly groups. This has corresponding
	changes to how filters are registered by core and extensions.
	* The edit form now uses pretty OOjs UI buttons, checkboxes and summary input.
	Because this change can cause problems for extensions and on-wiki
	scripts depending on the exact HTML, the old version is still available
	and can be used by setting $wgOOUIEditPage = false; in LocalSettings.php.
	This will be removed later and OOjs UI will become the only option.
	To make testing easier, users can also force either mode by adding
	&ooui=true or &ooui=false to the action=edit URL.

	=== External library changes in 1.29 ===

	==== Upgraded external libraries ====
	* Updated QUnit from v1.22.0 to v1.23.1.
	* Updated cssjanus from v1.1.2 to v1.2.0.

	according to the page content language, not wiki content language.
	* (T27187) Search suggestions based on jquery.suggestions will now correctly
	only highlight prefix matches in the results.
	* (T157035) "new mw.Uri()" was ignoring options when using default URI.

	* (T160519) CACHE_ANYTHING will not be CACHE_ACCEL if no accelerator is
	installed.
	* (T109140) (T122209) SECURITY: Special:UserLogin and Special:Search allow
	redirect to interwiki links.
	* (T144845) SECURITY: XSS in SearchHighlighter::highlightText() when
	$wgAdvancedSearchHighlighting is true.
	* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
	their values out of the logs.
	* (T150044) SECURITY: "Mark all pages visited" on the watchlist now requires a
	CSRF token.
	* (T156184) SECURITY: Escape content model/format url parameter in message.
	* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
	declaration.
	* (T161453) SECURITY: LocalisationCache will no longer use the temporary
	directory in it's fallback chain when trying to work out where to write the
	cache.
	* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file
	inclusion syntax's link parameter.
	* (T108138) SECURITY: Sysops can undelete pages, although the page is protected
	against it.

	=== Action API changes in 1.29 ===
	* Submitting sensitive authentication request parameters to action=login,
	action=clientlogin, action=createaccount, action=linkaccount, and
	action=changeauthenticationdata in the query string is now an error. They
	should be submitted in the POST body instead.
	* The capture option for action=resetpassword has been removed
	* action=clearhasmsg now requires a POST.
	* (T47843) API errors and warnings may be requested in non-English languages
	using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
	* API error codes may have changed. Most notably, errors from modules using
	parameter prefixes (e.g. all query submodules) will no longer be prefixed.
	* ApiPageSet-using modules will report the 'invalidreason' using the specified
	'errorformat'.
	* action=emailuser may return a "Warnings" status, and now returns 'warnings'
	and 'errors' subelements (as applicable) instead of 'message'.
	* action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
	* action=move now reports errors when moving the talk page as an array under
	key 'talkmove-errors', rather than using 'talkmove-error-code' and
	'talkmove-error-info'. The format for subpage move errors has also changed.
	* action=revisiondelete no longer includes a "rendered" property on warnings
	and errors for each item. Use errorformat=wikitext if you're wanting parsed
	output.
	* action=rollback no longer returns a "messageHtml" property. Use
	errorformat=html if you're wanting HTML formatting of error messages.
	* action=upload now reports optional stash failures as an array under key
	'stasherrors' rather than a 'stashfailed' text string.
	* action=watch reports 'errors' and 'warnings' instead of a single 'error', and
	no longer returns a 'message' on success.
	* Added action=validatepassword to validate passwords for the account creation
	and password change forms.
	* action=purge now requires a POST.
	* There is a new `languagevariants` siprop for action=query&meta=siteinfo,
	which returns a list of languages with active LanguageConverter instances.
	* action=query&query=allpages will no longer filter redirects using a database
	query in miser mode. This may result in less results being returned than were
	requested.

	=== Action API internal changes in 1.29 ===
	* New methods were added to ApiBase to handle errors and warnings using i18n
	keys. Methods for using hard-coded English messages were deprecated:
	* ApiBase::dieUsage() was deprecated
	* ApiBase::dieUsageMsg() was deprecated
	* ApiBase::dieUsageMsgOrDebug() was deprecated
	* ApiBase::getErrorFromStatus() was deprecated
	* ApiBase::parseMsg() was deprecated
	* ApiBase::setWarning() was deprecated
	* ApiBase::$messageMap is no longer public. Code attempting to access it will
	result in a PHP fatal error.
	* The $message parameter to the ApiCheckCanExecute hook should be set to an
	ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
	code for ApiBase::parseMsg() will no longer work.
	* UsageException is deprecated in favor of ApiUsageException. For the time
	being ApiUsageException is a subclass of UsageException to allow things that
	catch only UsageException to still function properly.
	* If, for some strange reason, code was using an ApiErrorFormatter instead of
	ApiErrorFormatter_BackCompat, note that the result format has changed and
	various methods now take a module path rather than a module name.
	* ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
	from the message key, and maps some message keys for backwards compatibility.
	* API parameters may now be marked as "sensitive" to keep their values out of
	the logs.

	=== Languages updated in 1.29 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Phabricator reports.

	* Based as always on linguistic studies on intelligibility and language
	knowledge by geography, language fallbacks have been expanded. When a
	translation is missing in the user's preferred interface language, the
	corresponding translation for the fallback language will be used instead.
	English will only be used as last resort when there are no translations.
	Some configurations (such as date formats and gender namespaces) have also
	been updated when using the fallback language's configuration was inadequate.
	The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
	ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
	sh → bs, sr-el, hr.
	* (T137376) New language support: Atikamekw (atj).
	* (T163600) New language support: Dinka (din).
	* (T155957) Talk Namespaces for Javanese language (jv) have been updated.

	==== No fallback for Ukrainian ====
	* (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
	language will now use the default fallback language: English. When a
	translation to Ukrainian is not available, an English string will be shown.

	=== Other changes in 1.29 ===
	* Database::getSearchEngine() (deprecated in 1.28) was removed. Use
	SearchEngineFactory::getSearchEngineClass() instead.
	* $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
	required as all sessions are stored in Object Cache now.
	* MWHttpRequest::execute() should be considered to return a StatusValue; the
	Status return type is deprecated.

	* WebRequest::checkSessionCookie() (deprecated in 1.27) was removed. Use
	\MediaWiki\Session\SessionManager::singleton()->getPersistedSessionId()
	instead.
	* Class ImageGallery (deprecated in 1.22) was removed.
	Use ImageGalleryBase::factory instead.
	* Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class
	instead.
	* Hook UnknownAction (deprecated in 1.19) was actually deprecated (it will now
	emit warnings). Create a subclass of Action and add it to $wgActions instead.
	* WikiRevision::getText() (deprecated since 1.21) is no longer marked
	deprecated.
	* Linker::getInterwikiLinkAttributes() (deprecated since 1.25) was removed.

	* The static properties mw.Api.errors and mw.Api.warnings, containing incomplete
	and outdated lists of errors/warnings returned by the API, are now deprecated.
	* wiki.phtml entry point was removed. Refer to index.php instead. If you want
	"wiki.phtml" URLs to continue to work, set up redirects. In Apache, this can
	be done by enabling mod_rewrite and adding the following rules to your
	configuration:

	RewriteEngine On
	RewriteBase /
	RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]
	* Hook ArticleAfterFetchContent (deprecated in 1.21) was removed.

	Use PageContentSaveComplete instead.
	* Hook EditFilterMerged (deprecated in 1.21) was removed.
	Use EditFilterMergedContent instead.
	* Hook EditPageGetPreviewText (deprecated in 1.21) was removed.
	Use EditPageGetPreviewContent instead.
	* Hook TitleIsCssOrJsPage (deprecated in 1.21) was removed.
	Use ContentHandlerDefaultModelFor instead.
	* Hook TitleIsWikitextPage (deprecated in 1.21) was removed.
	Use ContentHandlerDefaultModelFor instead.
	* Article::getContent() (deprecated in 1.21) was removed.
	* Revision::getText() (deprecated in 1.21) was removed.
	* Article::doEdit() and WikiPage::doEdit() (deprecated in 1.21) were removed.
	* Parser::replaceUnusualEscapes() (deprecated in 1.24) was removed.
	* Article::doEditContent() was marked as deprecated, to be removed in 1.30
	or later.
	* ContentHandler::runLegacyHooks() was removed.
	* refreshLinks.php now can be limited to a particular category with
	--category=... or a tracking category with --tracking-category=...
	* User-like objects that are passed to SpecialUserRights and its subclasses are
	now required to have a getGroupMemberships() method. See UserRightsProxy for
	an example.
	* User::$mGroups (instance variable) was marked private. Use User::getGroups()
	instead.
	* User::getGroupName(), User::getGroupMember(), User:getGroupPage(),
	User::makeGroupLinkHTML(), and User::makeGroupLinkWiki() were deprecated.
	Use equivalent methods on the UserGroupMembership class.
	* Maintenance scripts and tests that call User::addGroup() must now ensure that
	User objects have been added to the database prior to calling addGroup().
	* Protected function UsersPager::getGroups() was removed, and protected function
	UsersPager::buildGroupLink() was changed from a static to an instance method.
	* The third parameter ($cache) to the UsersPagerDoBatchLookups hook was changed;
	see docs/hooks.txt.
	* User::crypt() (deprecated in 1.24) was removed.
	* User::comparePasswords() (deprecated in 1.24) was removed.
	* ArchivedFile::getUserText() (deprecated in 1.23) was removed.
	* HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
	* BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
	and subclasses. It should only break if you call buildMainQueryConds
	(changed to buildQuery with new signature) or doMainQuery (new
	signature). Subclasses are likely to call at least doMainQuery
	(possibly both), but other classes might too, because they were
	public.
	Also, some related hooks were deprecated, but this is not yet a
	breaking change.
	* Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
	* The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
	* WikiRevision::$fileIsTemp was deprecated.
	* WikiRevision::$importer was deprecated.
	* WikiRevision::$user was deprecated.
	* Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
	WikiPage::PURGE_* constants are deprecated, and the functions will always
	return false. They were a hack for an issue that has since been fixed.
	* Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
	'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
	if you don't actually care about checkboxes and just want to add some HTML
	to the page.
	* Selflinks are now rendered as href-less <a> tags with the class mw-selflink
	rather than <strong> tags. The old class name, "selflink", was deprecated
	and will be removed in a future release. (T160480)
	* (T156184) $wgRawHtml will no longer apply to internationalization messages.
	* Browser support for non-ES5 JavaScript browsers, including Android 2,
	Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
	* Removed wikibits global methods deprecated since MediaWiki 1.17 (T122755):
	is_gecko, is_chrome_mac, is_chrome, webkit_version, is_safari_win, is_safari,
	webkit_match, is_ff2, ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs,
	opera7_bugs, opera6_bugs, is_opera_95, is_opera_preseven, is_opera,
	ie6_bugs, clientPC, changeText, killEvt, addHandler, hookEvent,
	addClickHandler, removeHandler, getElementsByClassName, getInnerText,
	setupCheckboxShiftClick, addCheckboxClickHandlers, mwEditButtons,
	mwCustomEditButtons, injectSpinner, removeSpinner, escapeQuotes,
	escapeQuotesHTML, jsMsg, addPortletLink, appendCSS, tooltipAccessKeyPrefix,
	tooltipAccessKeyRegexp, updateTooltipAccessKeys.
	* The ID of the <li> element containing the login link has changed from
	'pt-login' to 'pt-login-private' in private wikis.
	* The old, neglected "bulletin board style toolbar" in the edit form is now
	deprecated (T30856). This old code dates from 2006, and was replaced in the
	MediaWiki release tarball and in Wikimedia production by the WikiEditor
	extension in 2010. It is only shown to users if no other editor was
	installed, and leads to confusion.
	* (T92459) Loading ResourceLoader modules containing JavaScript through
	addModuleStyles() is deprecated and will log a warning server-side.

	== MediaWiki 1.28.2 ==

	Due to a packaging error, the wrong version of the SyntaxHighlight extension was
	included in the tarball version of MediaWiki 1.28.1. The version included had a
	serious security issue in it (T158689). There was also some minor code fixes in
	MediaWiki itself since 1.28.1, but none of them were security relevant.

	== MediaWiki 1.28.1 ==

	This is a security and maintenance release of the MediaWiki 1.28 branch.

	=== Changes since 1.28.0 ===

	* $wgRunJobsAsync is now false by default (T142751). This change only affects
	wikis with $wgJobRunRate > 0.
	* Fix fatal from "WaitConditionLoop" not being found, experienced when a wiki
	has more than one database server setup.
	* (T152717) Better escaping for PHP mail() command,
	* (T154670) A missing method causing the MySQL installer to fatal in rare
	circumstances was restored.
	* (T154672) Un-deprecate ArticleAfterFetchContentObject hook.
	* (T158766) Avoid SQL error on MSSQL when using selectRowCount().
	* (T145635) Fix too long index error when installing with MSSQL.
	* (T156184) $wgRawHtml will no longer apply to internationalization messages.
	* (T160519) CACHE_ANYTHING will not be CACHE_ACCEL if no accelerator is
	installed.
	* (T154872) Fix incorrect ar_usertext_timestamp index names in new 1.28
	installs.
	* (T109140) (T122209) SECURITY: Special:UserLogin and Special:Search allow
	redirect to interwiki links.
	* (T144845) SECURITY: XSS in SearchHighlighter::highlightText() when
	$wgAdvancedSearchHighlighting is true.
	* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
	their values out of the logs.
	* (T150044) SECURITY: "Mark all pages visited" on the watchlist now requires a
	CSRF token.
	* (T156184) SECURITY: Escape content model/format url parameter in message.
	* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
	declaration.
	* (T161453) SECURITY: LocalisationCache will no longer use the temporary
	directory in it's fallback chain when trying to work out where to write the
	cache.
	* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file
	inclusion syntax's link parameter.
	* (T108138) SECURITY: Sysops can undelete pages, although the page is protected
	against it.

	== MediaWiki 1.28 ==

	=== Changes since 1.28.0-rc1 ===
	* (T148957) Replace wgShowExceptionDetails with wgShowDBErrorBacktrace on db
	errors.
	* (T148956) Only apply wgDBschema to postgres/mssql.
	* (T145991) Introduce separate log action for deleting pages on move.
	* (T141474) (T110464) Bypass login page if no user input is required.

	=== Changes since 1.28.0-rc0 ===
	* (T142210) The changes to move the parser "NewPP limit report" from a HTML
	comment to a machine-readable JavaScript config option 'wgPageParseReport'
	have been undone. They caused the human-readable limit report to be shown
	incompletely or not at all. ParserOutput::setLimitReportData() and
	getLimitReportData() behave as they did in MediaWiki 1.27 again.
	* (T149510) Value of {{DISPLAYTITLE:}} parser function will not be used for
	the text of subheadings on a category page when creating it. This wasn't
	working correctly.
	* (T106793) MediaWiki will no longer try to perform a HTTP redirect to the
	canonical pretty URL when a non-pretty URL is used. It resulted in redirect
	loops in some clients and in some server configurations. This undoes a change
	made in MediaWiki 1.26.
	* (T149759) manifest_version: 2 was removed.

	=== Configuration changes in 1.28 ===
	* $wgSend404Code now affects status code of action=history if the page is not
	there.
	* BREAKING CHANGE: $wgHTTPProxy is now required for all external requests
	made by MediaWiki via a proxy. Relying on the http_proxy environment
	variable is no longer supported.
	* The load.php entry point now enforces the existing policy of not allowing
	access to session data, which includes the session user and the session
	user's language. If such access is attempted, an exception will be thrown.
	* The number of internal PBKDF2 iterations used to derive the session secret
	is configurable via $wgSessionPbkdf2Iterations.
	* Upload dialog's file upload log comment can now be configured separately for
	local and foreign uploads.
	* $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
	signifies local uploads. A value of `[]` (empty array) now means that
	no upload targets are allowed, effectively disabling the upload dialog.
	* The deprecated $wgEditEncoding variable has been removed; it was only used
	for Esperanto language character conversion. You are now recommended to use
	input methods provided by the UniversalLanguageSelector extension.
	* When $wgPingback is true, MediaWiki will periodically ping
	https://www.mediawiki.org/beacon with basic information about the local
	MediaWiki installation. This data includes, for example, the type of system,
	PHP version, and chosen database backend. This behavior is off by default.
	* When $wgEditSubmitButtonLabelPublish is true, MediaWiki will label the button
	to store-to-database-and-show-to-others as "Publish page"/"Publish changes";
	if false, the default, they will be "Save page"/"Save changes".
	* The 'editcontentmodel' permission is now granted to all logged-in users
	('user').
	instead of just administrators ('sysop'). Documentation for this feature is
	available at <https://www.mediawiki.org/wiki/Help:ChangeContentModel>.
	* $wgRevisionCacheExpiry is now set to one week by default instead of being
	disabled.
	* Magic links are now disabled by default, and can be re-enabled by modifying
	the value of $wgEnableMagicLinks. Their usage is discouraged, but if they are
	manually enabled, a tracking category will be added to help identify usage and
	make it easier to migrate away from. If you depend upon magic link
	functionality, it is requested that you comment on
	<https://www.mediawiki.org/wiki/Requests_for_comment/Future_of_magic_links>
	and explain your use case(s).
	* New config variable $wgCSPFalsePositiveUrls to control what URLs to ignore
	in upcoming Content-Security-Policy feature's reporting.

	=== New features in 1.28 ===
	* User::isBot() method for checking if an account is a bot role account.
	* Added a new 'slideshow' mode for galleries.
	* Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
	* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
	interact with API parsing.
	* Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
	upload. Unlike 'UploadVerifyFile' it provides information about upload comment
	and the file description page, but does not run for uploads to stash.
	* (T141604) Extensions can now provide a better error message when their
	maintenance scripts are run without the extension being installed.
	* (T8948) Numeric sorting in categories is now supported by setting
	$wgCategoryCollation to 'uca-default-u-kn' or 'uca-<langcode>-u-kn'. If you
	can't use UCA collations, a 'numeric' collation is also available. If
	migrating from another collation, you will need to run the updateCollation.php
	maintenance script.
	* Two new codes have been added to #time parser function: "xit" for days in
	current month, and "xiz" for days passed in the year, both in Iranian
	calendar.
	* mw.Api has a new option, useUS, to use U+001F (Unit Separator) when
	appropriate for sending multi-valued parameters. This defaults to true when
	the mw.Api instance seems to be for the local wiki.
	* After a client performs an action which alters a database that has replica
	databases, MediaWiki will wait for the replica databases to synchronize with
	the master database while it renders the HTML output. However, if the output
	is a redirect to another wiki on the wiki farm with a different domain,
	MediaWiki will instead alter the redirect URL to include a ?cpPosTime
	parameter that triggers the database synchronization when the URL is followed
	by the client. The same-domain case uses a new cpPosTime cookie.
	* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
	'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
	'show' parameters to existing API query modules.

	=== External library changes in 1.28 ===

	==== Upgraded external libraries ====
	* Updated es5-shim from v4.1.5 to v4.5.8
	* Updated composer/semver from v1.4.1 to v1.4.2
	* Updated wikimedia/php-session-serializer from v1.0.3 to v1.0.4

	==== New external libraries ====
	* Added wikimedia/scoped-callback v1.0.0
	* Added wikimedia/wait-condition-loop v1.0.1

	=== Bug fixes in 1.28 ===
	* (T146496) action=history pages should return 404 HTTP error code if the page
	does not exist
	* (T137264) SECURITY: XSS in unclosed internal links
	* (T133147) SECURITY: Escape '<' and ']]>' in inline <style> blocks
	* (T133147) SECURITY: Require login to preview user CSS pages
	* (T132926) SECURITY: Do not allow undeleting a revision deleted file if it is
	the top file
	* (T129738) SECURITY: Make $wgBlockDisablesLogin also restrict logged in
	permissions
	* (T129738) SECURITY: Make blocks log users out if $wgBlockDisablesLogin is true
	* (T139670) Move 'UserGetRights' call before application of
	Session::getAllowedUserRights()

	=== Action API changes in 1.28 ===
	* Added 'maxarticlesize' property to action=query&meta=siteinfo which contains
	the value of $wgMaxArticleSize.
	* Property 'modulemessages' from action=parse&prop=modules was removed
	(deprecated since 1.26).
	* The following response properties from action=login, deprecated in 1.27, are
	now removed: lgtoken, cookieprefix, sessionid. Clients should handle cookies
	to properly manage session state.
	* Submitting the lgtoken and lgpassword parameters in the query string to
	action=login is now deprecated and outputs a warning. They should be submitted
	in the POST body instead.
	* Submitting sensitive authentication request parameters to action=clientlogin,
	action=createaccount, action=linkaccount, and action=changeauthenticationdata
	in the query string is now deprecated and outputs a warning. They should be
	submitted in the POST body instead.
	* (T141960) Multi-valued parameters may now be separated using U+001F
	(Unit Separator) instead of the pipe character. This will be useful if some of
	the multiple values need to contain pipes, e.g. for action=options.
	* The API will now warn if input is not NFC-normalized Unicode or if it
	contains invalid characters.
	* The 'normalized' list output by action=query and other modules that use
	ApiPageSet may contain entries where the 'from' value is percent-encoded as
	the raw value cannot be represented in a valid API response. These are
	indicated by a 'fromencoded' boolean alongside the existing 'from' parameter.
	* (T28680) action=paraminfo can now return info about all submodules of a
	module without listing them all explicitly.
	* (T146770) It is now possible to assert that the current user is a specific
	named user, using the 'assertuser' parameter.
	* (T141963) Added a 'known' property when missing-but-known titles (e.g. from
	the 'TitleIsAlwaysKnown' hook) are output in various modules.

	=== Action API internal changes in 1.28 ===
	* Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
	interact with ApiParse and ApiExpandTemplates.
	* (T139565) SECURITY: API: Generate head items in the context of the given title
	* (T115333) SECURITY: Check read permission when loading page content in
	ApiParse
	* ApiBase::getResultData() was removed (deprecated since 1.25)
	* ApiBase::makeHelpArrayToString() was removed (deprecated since 1.25)
	* ApiBase::makeHelpMsgParameters() was removed (deprecated since 1.25)

	* ApiFormatBase::getWantsHelp() was removed (deprecated since 1.25)
	* ApiFormatBase::setBufferResult() was removed (deprecated since 1.25)
	* ApiFormatBase::setHelp() was removed (deprecated since 1.25)
	* ApiFormatBase::setUnescapeAmps() was removed (deprecated since 1.25)
	* ApiMain::makeHelpMsgHeader() was removed (deprecated since 1.25)
	* ApiMain::reallyMakeHelpMsg() was removed (deprecated since 1.25)
	* ApiMain::setHelp() was removed (deprecated since 1.25)
	* ApiResult::beginContinuation() was removed (deprecated since 1.25)
	* ApiResult::cleanUpUTF8() was removed (deprecated since 1.25)
	* ApiResult::convertStatusToArray() was removed (deprecated since 1.25)
	* ApiResult::disableSizeCheck() was removed (deprecated since 1.24)
	* ApiResult::enableSizeCheck() was removed (deprecated since 1.24)
	* ApiResult::endContinuation() was removed (deprecated since 1.25)
	* ApiResult::getData() was removed (deprecated since 1.25)
	* ApiResult::getIsRawMode() was removed (deprecated since 1.25)
	* ApiResult::setContent() was removed (deprecated since 1.25)
	* ApiResult::setContinueParam() was removed (deprecated since 1.25)
	* ApiResult::setElement() was removed (deprecated since 1.25)
	* ApiResult::setGeneratorContinueParam() was removed (deprecated since 1.25)
	* ApiResult::setIndexedTagName_internal() was removed (deprecated since 1.25)
	* ApiResult::setIndexedTagName_recursive() was removed (deprecated since 1.25)
	* ApiResult::setMainForContinuation() was removed (deprecated since 1.25)
	* ApiResult::setParsedLimit() was removed (deprecated since 1.25)
	* ApiResult::setRawMode() was removed (deprecated since 1.25)
	* ApiResult::size() was removed (deprecated since 1.25)
	* Added new hooks, 'ApiQueryBaseBeforeQuery', 'ApiQueryBaseAfterQuery', and
	'ApiQueryBaseProcessRow', to make it easier for extensions to add 'prop' and
	'show' parameters to existing API query modules. A query module can enable
	these hooks by passing an array for $hookData to ApiQueryBase::select() and
	by calling ApiQueryBase->processRow() before adding a row's data to the
	result.

	=== Languages updated in 1.28 ===

	MediaWiki supports over 375 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Phabricator reports.

	* (T137411) ban (Balinese), thanks to translators Adi Mayndra, Andru,
	BASAbali, M. Adiputra, Naval Scene, Nemo bis, NoiX180, and 아라.

	MediaWiki\Linker\LinkRenderer. In addition, the LinkBegin and LinkEnd hooks
	were replaced by HtmlPageLinkRendererBegin and HtmlPageLinkRendererEnd
	respectively. See docs/hooks.txt for the specific changes needed for those
	hooks.
	* Linker::formatSize() was deprecated. Use Language::formatSize() directly.
	* Aliases for Linker methods, deprecated since 1.21, were removed from Skin:
	* Skin::commentBlock() (use Linker::commentBlock() instead)

	* Disabled "bug 2702" HTML tidying of parsed UI messages on wikis where Tidy is
	disabled.
	* DifferenceEngine::generateDiffBody() was removed (deprecated since 1.21).
	* UploadBase::stashFileGetKey() and UploadBase::stashSession() were deprecated.
	Use ...->stashFile()->getFileKey() instead.
	* "Public domain" was removed as a wiki license option from the installer, in
	favour of CC-0.
	* AuthenticationRequest::$required is now changed from REQUIRED to
	PRIMARY_REQUIRED on requests needed by primary providers even if all primaries
	need them.
	Primary providers are discouraged from returning multiple REQUIRED requests.
	* OOjs UI PHP widgets constructed with the `'infusable' => true` config option
	will no longer be automatically infused. You should call `OO.ui.infuse()`
	on them yourself from your JavaScript code.
	* parserTests.php has moved to tests/parser/parserTests.php
	* The command line options specific to parser tests have been removed from
	phpunit.php: --regex and --keep-uploads. Instead of --regex, use --filter.
	Instead of --keep-uploads, use the same option to parserTests.php, but you
	must specify a directory with --upload-dir.
	* The 'jquery.arrowSteps' ResourceLoader module is now deprecated.
	* IP::isConfiguredProxy() and IP::isTrustedProxy() were removed. Callers should
	migrate to using the same functions on a ProxyLookup instance, obtainable from
	MediaWikiServices.
	* The ArticleAfterFetchContent, ArticleInsertComplete, ArticleSave,
	ArticleSaveComplete, ArticleViewCustom, EditFilterMerged, EditPageGetDiffText,
	EditPageGetPreviewText and ShowRawCssJs hooks will now emit deprecation
	warnings if used.
	* (T68404) CSS3 attr() function with url type is no longer allowed
	in inline styles.
	* Database::getSearchEngine() is deprecated, use
	SearchEngineFactory::getSearchEngineClass instead.

	== Compatibility ==

	MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
	HHVM 3.6.5 or later.

	MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
	support for them is somewhat less mature. There is experimental support for
	Oracle and Microsoft SQL Server.

	The supported versions are:

	* MySQL 5.0.3 or later
	* PostgreSQL 8.3 or later
	* SQLite 3.3.7 or later
	* Oracle 9.0.1 or later
	* Microsoft SQL Server 2005 (9.00.1399)

	== Upgrading ==

	1.28 has several database changes since 1.27, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	If upgrading from before 1.11, and you are using a wiki as a commons
	repository, make sure that it is updated as well. Otherwise, errors may arise
	due to database schema changes.

	If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
	new database fields are filled with data.

	If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
	1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
	with MediaWiki 1.21.

	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions.

	For notes on 1.27.x and older releases, see HISTORY.

	== Online documentation ==

	Documentation for both end-users and site administrators is available on
	MediaWiki.org, and is covered under the GNU Free Documentation License (except
	for pages that explicitly state that their contents are in the public domain):

	https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation

	== Mailing list ==

	A mailing list is available for MediaWiki user support and discussion:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

	A low-traffic announcements-only list is also available:

	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

	It's highly recommended that you sign up for one of these lists if you're
	going to run a public MediaWiki, so you can be notified of security fixes.

	== IRC help ==

	There's usually someone online in #mediawiki on irc.freenode.net.

	== MediaWiki 1.27.3 ==
	Due to a packaging error, the wrong version of the SyntaxHighlight extension was
	included in the tarball version of MediaWiki 1.27.2. The version included had a
	serious security issue in it (T158689). There was also some minor code fixes in
	MediaWiki itself since 1.27.2, but none of them were security relevant.

	=== Changes since 1.27.2 ===
	* (T145664) Fix broken wincache merge() implementation
	* (T163434) Add wikimedia/testing-access-wrapper for forwards compatibility
	* (T153505) Fix php warnings on php 7.1 due to use of &$this

	== MediaWiki 1.27.2 ==
	This is a security and maintenance release of the MediaWiki 1.27 branch.

	ApiCreateAccount was removed in 1.27.0. It was incorrectly still marked as
	deprecated (rather than already removed) in the RELEASE-NOTES at the point
	1.27.0 was released.

	=== Changes since 1.27.1 ===

	* (T68404) CSS3 attr() function with url type argument is no longer allowed
	in inline styles.
	* $wgRunJobsAsync is now false by default (T142751). This change only affects
	wikis with $wgJobRunRate > 0.
	* (T152717) Better escaping for PHP mail() command
	* Submitting the lgtoken and lgpassword parameters in the query string to
	action=login is now deprecated and outputs a warning. They should be submitted
	in the POST body instead.
	* Submitting sensitive authentication request parameters to action=clientlogin,
	action=createaccount, action=linkaccount, and action=changeauthenticationdata
	in the query string is now deprecated and outputs a warning. They should be
	submitted in the POST body instead.
	* (T158766) Avoid SQL error on MSSQL when using selectRowCount()
	* (T145635) Fix too long index error when installing with MSSQL.
	* (T156184) $wgRawHtml will no longer apply to internationalization messages.
	* (T160519) CACHE_ANYTHING will not be CACHE_ACCEL if no accelerator is
	installed.
	* (T109140) (T122209) SECURITY: Special:UserLogin and Special:Search allow
	redirect to interwiki links.
	* (T144845) SECURITY: XSS in SearchHighlighter::highlightText() when
	$wgAdvancedSearchHighlighting is true.
	* (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
	their values out of the logs.
	* (T150044) SECURITY: "Mark all pages visited" on the watchlist now requires a
	CSRF token.
	* (T156184) SECURITY: Escape content model/format url parameter in message.
	* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
	declaration.
	* (T161453) SECURITY: LocalisationCache will no longer use the temporary
	directory in it's fallback chain when trying to work out where to write the
	cache.
	* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file
	inclusion syntax's link parameter.
	* (T108138) SECURITY: Sysops can undelete pages, although the page is protected
	against it.

	== MediaWiki 1.27.1 ==

	This is a maintenance release of the MediaWiki 1.27 branch.

	=== Changes since 1.27.0 ===
	* BREAKING CHANGE: $wgHTTPProxy is now required for all external requests
	made by MediaWiki via a proxy. Relying on the http_proxy environment
	variable is no longer supported.
	* (T139565) SECURITY: API: Generate head items in the context of the given title
	* (T137264) SECURITY: XSS in unclosed internal links
	* (T133147) SECURITY: Escape '<' and ']]>' in inline <style> blocks
	* (T133147) SECURITY: Require login to preview user CSS pages
	* (T132926) SECURITY: Do not allow undeleting a revision deleted file if it is
	the top file

	permissions
	* (T129738) SECURITY: Make blocks log users out if $wgBlockDisablesLogin is true
	* (T115333) SECURITY: Check read permission when loading page content in
	ApiParse
	* (T57548) Remove support for $wgWellFormedXml = false, all output is now well
	formed
	* (T139670) Move 'UserGetRights' call before application of
	Session::getAllowedUserRights()

	== MediaWiki 1.27.0 ==

	=== PHP version requirement in 1.27 ===
	As of 1.27, MediaWiki now requires PHP 5.5.9 or higher (see Compatibility
	section). Additionally, the following PHP extensions are required:
	* ctype
	* iconv
	* json
	* mbstring (new requirement in 1.27)
	* xml
	The following PHP extensions are strongly recommended:
	* openssl

	=== Configuration changes in 1.27 ===
	* $wgAllowMicrodataAttributes and $wgAllowRdfaAttributes were removed,
	now always enabled. If you use RDFa on your wiki, you now have to explicitly
	set $wgHtml5Version to 'HTML+RDFa 1.0' or 'XHTML+RDFa 1.0'.
	* $wgUseLinkNamespaceDBFields was removed.
	* Deprecated $wgResourceLoaderMinifierStatementsOnOwnLine and
	$wgResourceLoaderMinifierMaxLineLength, because there was little value in
	making the behavior configurable. The default values (`false` for the former,
	1000 for the latter) are now hard-coded.
	* $wgDebugDumpSqlLength was removed (deprecated in 1.24).
	* $wgDebugDBTransactions was removed (deprecated in 1.20).
	* $wgUseXVO has been removed, as it provides functionality only used by
	custom Wikimedia patches against Squid 2.x that probably noone uses in
	production anymore. There is now $wgUseKeyHeader that provides similar
	functionality but instead of the MediaWiki-specific X-Vary-Options header,
	uses the draft Key header standard.
	* $wgScriptExtension (and support for '.php5' entry points) was removed. See the
	deprecation notice in the release notes for version 1.25 for advice on how to
	preserve support for '.php5' entry points via URL rewriting.
	* Password handling via the User object has been deprecated and partially
	removed, pending the future introduction of AuthManager. In particular:
	** expirePassword(), getPasswordExpireDate(), resetPasswordExpiration(), and
	getPasswordExpired() have been removed. They were unused outside of core.
	** The mPassword, mNewpassword, mNewpassTime, and mPasswordExpires fields are
	now private and will be removed in the future.
	** The getPassword() and getTemporaryPassword() methods now throw
	BadMethodCallException and will be removed in the future.
	** The ability to pass 'password' and 'newpassword' to createNew() has been
	removed. The only users of it seem to have been using it to set invalid
	passwords, and so shouldn't be greatly affected.
	** setPassword(), setInternalPassword(), and setNewpassword() have been
	deprecated, pending the introduction of AuthManager.
	** User::randomPassword() is deprecated in favor of a new method
	PasswordFactory::generateRandomPasswordString()
	** User::getPasswordFactory() is deprecated, callers should just create a
	PasswordFactory themselves.
	** A new constructor, User::newSystemUser(), has been added to simplify the
	creation of passwordless "system" users for logged actions.
	* $wgMaxSquidPurgeTitles was removed.
	* $wgAjaxWatch was removed. This is now enabled by default.
	* $wgUseInstantCommons now hotlinks Commons images by default instead of
	downloading originals and thumbnailing them locally. This allows wikis to save
	on CPU and bandwidth while reducing time to first byte for pages, even without
	a thumbnail handler. See $wgForeignFileRepos documentation for tweaks.
	* (T27397) WebP is enabled by default as an uploadable filetype.
	* (T48998) $wgArticlePath must now be either a full url, or start with a "/".
	* $wgRateLimitLog was removed; use $wgDebugLogGroups['ratelimit'] instead.
	* Deprecated API formats dbg, txt, and yaml have been removed.
	* CLDRPluralRule* classes have been replaced with
	wikimedia/cldr-plural-rule-parser.
	* Removed $wgProfilePerHost, $wgUDPProfilerHost, $wgUDPProfilerPort,
	$wgUDPProfilerFormatString, $wgStatsMethod, $wgAggregateStatsID,
	$wgStatsFormatString, and $wgProfileCallTree (deprecated since 1.20).
	* For proper operation of LocalIdLookup with shared user tables, ensure that
	$wgSharedDB and $wgSharedTables are properly set even on the "central" wiki
	that all others are sharing from and that $wgLocalDatabases is set to the
	full list of sharing wikis on all those wikis.
	* Massive overhaul to session handling:
	** $wgSessionsInObjectCache is no longer supported and must be true, due to
	MediaWiki\Session\SessionManager. $wgSessionHandler is similarly no longer
	used.
	** ObjectCacheSessionHandler is removed, replaced with
	MediaWiki\Session\PhpSessionHandler.
	** PHP session handling in general ($_SESSION, session_id(), and so on) is
	deprecated. Use MediaWiki\Session\SessionManager instead. A new config
	variable, $wgPHPSessionHandling, is available to cause use of $_SESSION to
	issue a deprecation warning or to cause most PHP session handling to throw
	exceptions.
	** Deprecated UserSetCookies hook. Session-handling extensions should generally
	be creating a custom subclass of CookieSessionProvider. Other extensions
	messing with cookies can no longer count on user data being saved in cookies
	versus other methods.
	** Deprecated UserLoadFromSession hook, extensions should create a
	MediaWiki\Session\SessionProvider.
	** The User cannot be loaded from session until after Setup.php completes.
	Attempts to do so will be ignored and the User will remain unloaded.
	** CSRF tokens may be fetched from the MediaWiki\Session\Session, which uses
	the MediaWiki\Session\Token class.
	* MediaWiki will now auto-create users as necessary, removing the need for
	extensions to do so. An 'autocreateaccount' right is added to allow
	auto-creation when 'createaccount' is not granted to all users.
	* Deprecated AuthPluginAutoCreate hook in favor of LocalUserCreated.
	* Most cookie-handling methods in User are deprecated.
	* $wgAllowAsyncCopyUploads and $CopyUploadAsyncTimeout were removed. This was an
	experimental feature that has never worked.
	* Login and createaccount tokens now vary by timestamp.
	* LoginForm::getLoginToken() and LoginForm::getCreateaccountToken()
	return a MediaWiki\Session\Token, and tokens must be checked using that
	class's methods.
	* $wgEnotifUseJobQ was removed and the job queue is always used.
	* The functionality of the ApiSandbox extension has been merged into core. The
	extension should no longer be used.
	* $wgPreloadJavaScriptMwUtil was removed (deprecated in 1.26).
	Extensions, skins, gadgets and scripts that use the mediawiki.util module must
	express a dependency on it.
	* $wgIncludeLegacyJavaScript, deprecated in MediaWiki 1.26, now defaults false.
	Extensions, skins, gadgets and scripts that need the mediawiki.legacy.wikibits
	module should express a dependency on it.
	* Removed configuration option $wgCopyrightIcon (deprecated since 1.18). Use
	$wgFooterIcons['copyright']['copyright'] instead.
	* If the openssl and mcrypt PHP extensions are both unavailable, secure
	session storage (used for login) will raise an exception. This exception may
	be bypassed by setting $wgSessionInsecureSecrets = true.
	* Massive overhaul to authentication:
	** AuthPlugin and AuthPluginUser are deprecated.
	** LoginForm and associated templates are deprecated. Extensions which called
	static LoginForm methods should be converted into authentication providers.
	** The following hooks are deprecated:
	*** AbortAutoAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
	*** AbortLogin (create a MediaWiki\Auth\PreAuthenticationProvider instead)
	*** AbortNewAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
	*** AddNewAccount (use LocalUserCreated instead)
	*** AuthPluginSetup (create a MediaWiki\Auth\PrimaryAuthenticationProvider
	instead)
	*** ChangePasswordForm (use AuthChangeFormFields instead, or security levels)
	*** LoginUserMigrated (create a MediaWiki\Auth\PreAuthenticationProvider
	instead)
	*** UserCreateForm (create a MediaWiki\Auth\AuthenticationProvider of some type
	instead)
	*** UserLoginForm (create a MediaWiki\Auth\AuthenticationProvider of some type
	instead)
	** The following hooks are removed:
	*** AbortChangePassword
	*** LoginPasswordResetMessage
	*** PrefsPasswordAudit
	** The UserLoginComplete hook will no longer be called for all logins, only for
	those via the web UI. Use UserLoggedIn if you need to do something on all
	logins.
	** $wgRequirePasswordforEmailChange is removed.

	=== New features in 1.27 ===
	* $wgDataCenterUpdateStickTTL was also added. This decides how long a user
	sticks to the primary DC (via cookies) after they make changes to the site.
	* Added a new hook, 'UserMailerTransformContent', to transform the contents
	of an email. This is similar to the EmailUser hook but applies to all mail
	sent via UserMailer.
	* Added a new hook, 'UserMailerTransformMessage', to transform the contents
	of an emai after MIME encoding.
	* Added a new hook, 'UserMailerSplitTo', to control which users have to be
	emailed separately (ie. there is a single address in the To: field) so
	user-specific changes to the email can be applied safely.
	* $wgCdnMaxageLagged was added, which limits the CDN cache TTL
	when any load balancer uses a DB that is lagged beyond the 'max lag'
	setting in the relevant section of $wgLBFactoryConf.
	* User::newSystemUser() may be used to simplify the creation of passwordless
	"system" users for logged actions from scripts and extensions.
	* Extensions can now return detailed error information via the API when
	preventing user actions using 'getUserPermissionsErrors' and similar hooks
	by using ApiMessage instances instead of strings for the $result value.
	* $wgAPIMaxLagThreshold was added to limit bot changes when databases lag
	becomes too high.
	* Skins and extensions can now use FlexBox mixins (.flex-display(@display: flex)
	and .flex(@grow: 1, @shrink: 1, @width: auto, @order: 1)) in Less to create
	cross-browser-compatible FlexBox rules. Users will still need to add fallback
	float rules or the like for compatibility with IE9- separately.
	* Added MWTimestamp::getTimezoneString() which returns the localized timezone
	string, if available. To localize this string, see the comments of
	$wgLocaltimezone in includes/DefaultSettings.php.
	* Added CentralIdLookup, a service that allows extensions needing a concept of
	"central" users to get that without having to know about specific central
	authentication extensions.
	* $wgMaxUserDBWriteDuration added to limit huge user-generated transactions.
	Regular web request transactions that takes longer than this are aborted.
	* Added a new hook, 'TitleMoveCompleting', which runs before a page move is
	committed.
	* $wgCdnReboundPurgeDelay was added to provide secondary delayed purges of URLs
	from CDN to mitigate DB replication lag and WAN cache purge lag.
	* (T49162) Installer will default to setting CACHE_ACCEL as the main cache type
	if it is available.
	* It is now possible to patrol file uploads (both for new files and new versions
	of existing files). Special:NewFiles has gained an option to filter by patrol
	status. This functionality can be disabled using $wgUseFilePatrol.
	* MediaWiki\Session infrastructure allows for easier use of session mechanisms
	other than the usual cookies.
	** SessionMetadata and SessionCheckInfo hooks allow for setting and checking
	custom session metadata.
	* Added MWGrants and associated configuration settings $wgGrantPermissions and
	$wgGrantPermissionGroups to hold configuration for authentication features
	such as OAuth that want to allow restricting the user rights a user may make
	use of.
	** If you're already using the OAuth extension, these new variables are
	identical to (and will replace) $wgMWOAuthGrantPermissions and
	$wgMWOAuthGrantPermissionGroups.
	* Added MWRestrictions as a class to check restrictions on a WebRequest, e.g.
	to assert that the request comes from a particular IP range.
	* Added bot passwords, a rights-restricted login mechanism for API-using bots.
	* Whitelisted the following HTML attributes for all elements in wikitext:
	aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
	* Removed "presentation" restriction on the HTML role attribute in wikitext.
	All values are now allowed for the role attribute.
	* $wgContentHandlers now also supports callbacks to create an instance of the
	appropriate ContentHandler subclass.
	* Added $wgAuthenticationTokenVersion, which if non-null prevents the
	user_token database field from being exposed in cookies. Setting this would
	be a good idea, but will log out all current sessions.
	* $wgEventRelayerConfig was added, for managing PubSub event relay
	configuration, specifically for reliable CDN url purges.
	* Requests have unique IDs, equal to the UNIQUE_ID environment variable (when
	MediaWiki is behind Apache+mod_unique_id or something similar) or a randomly-
	generated 24-character string. This request ID is used to annotate log records
	and error messages. It is available client-side via
	mw.config.get( 'wgRequestId' ).
	The request ID supplants exception IDs. Accordingly,
	MWExceptionHandler::getLogId() is deprecated.
	* (T33313) Add a preference for watching uploads by default, also applies
	to API-based upload tools.
	* $wgJpegPixelFormat was added to override chroma subsampling for JPEG image
	thumbnails created via ImageMagick. Defaults to 'yuv420', providing bandwidth
	savings versus the previous behavior on many files.
	* MediaWiki\Auth infrastructure (called "AuthManager") allows for more flexible
	configuration of multiple authentication pieces that was possible with
	AuthPlugin. For example, it's now easy to plug in second-factor
	authentication, or add additional checks to the login process, or to support
	multiple login methods at once, or to support non-password-based login
	methods.
	** Providers are configured via the global setting $wgAuthManagerConfig.
	** A global, $wgDisableAuthManager, is temporarily available to disable
	AuthManager until extensions are ready to support it.
	** New hook, AuthChangeFormFields, to adjust the form fields on
	AuthManager-related special pages.
	** New hook, AuthManagerLoginAuthenticateAudit, for additional logging of
	AuthManager-related authentication requests.
	** New hook, ChangeAuthenticationDataAudit, for additional logging of
	AuthManager-related authentication data changes.
	** New hook, SecuritySensitiveOperationStatus, to work with the new mechanism
	for requiring a recent login before taking security-sensitive operations
	like changing a password.
	** Two new globals, $wgChangeCredentialsBlacklist and
	$wgRemoveCredentialsBlacklist can be used to prevent the web UI and the API
	changing certain authentication data.
	* The file upload dialog (available if you install WikiEditor or VisualEditor)
	can now be configured using $wgUploadDialog.

	=== External library changes in 1.27 ===

	==== Upgraded external libraries ====
	* Updated oojs/oojs-ui from v0.12.12 to v0.13.3.
	* Updated composer/semver from v1.0.0 to v1.2.0.

	=== Bug fixes in 1.27 ===
	* Special:Upload will now display correct maximum allowed file size when running
	under HHVM (T116347).
	* (T54077) The APIEditBeforeSave hook will once again give only the content of
	the section being edited, rather than the whole revision. This reverts the
	change made in MediaWiki 1.22.

	=== Action API changes in 1.27 ===
	* Added list=allrevisions.
	* generator=recentchanges now has the option to generate revids.
	* ApiPageSet::setRedirectMergePolicy() was added. This allows generator
	modules to define how generator data for a redirect source gets merged
	into the redirect destination.
	* prop=imageinfo&iiprop=uploadwarning will no longer include the possibility of
	"was-deleted" warning.
	* Added difftotextpst to query=revisions which preforms a pre-save transform on
	the text before diffing it.
	* Deprecated formats dbg, txt, and yaml have been removed.
	* (T47988) The protect log event details now use new-style formatting.
	* The following response properties from action=login are deprecated, and may
	be removed in the future: lgtoken, cookieprefix, sessionid. Clients should
	handle cookies to properly manage session state.
	* action=login transparently allows login using bot passwords. Clients should
	merely need to change the username and password used after setting up a bot
	password.
	* action=upload no longer understands statuskey, asyncdownload or leavemessage.
	* Several changes when $wgDisableAuthManager is false:
	** action=login is deprecated for uses other than bot passwords.
	** list=users can now indicate if a missing username is creatable.
	** action=createaccount is changed in a non-backwards-compatible manner.
	** Added action=query&meta=authmanagerinfo.
	** Added action=clientlogin to be used to log into the main account instead of
	action=login.
	** Added action=linkaccount.
	** Added action=unlinkaccount.

	=== Languages updated in 1.27 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as

	=== Compatibility ===

	MediaWiki 1.27 requires PHP 5.5.9 or later. There is experimental support for
	HHVM 3.6.5 or later.

	MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
	support for them is somewhat less mature. There is experimental support for
	Oracle and Microsoft SQL Server.

	The supported versions are:

	* MySQL 5.0.3 or later
	* PostgreSQL 8.3 or later
	* SQLite 3.3.7 or later
	* Oracle 9.0.1 or later
	* Microsoft SQL Server 2005 (9.00.1399)

	=== Upgrading ===

	1.27 has several database changes since 1.26, and will not work without schema
	updates. Note that due to changes to some very large tables like the revision
	table, the schema update may take quite long (minutes on a medium sized site,
	many hours on a large site).

	If upgrading from before 1.11, and you are using a wiki as a commons
	repository, make sure that it is updated as well. Otherwise, errors may arise
	due to database schema changes.

	If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
	new database fields are filled with data.

	If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
	1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
	with MediaWiki 1.21.

	Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions.

	For notes on 1.26.x and older releases, see HISTORY.

	* $wgPasswordResetRoutes['email'] = true by default.
	* $wgEnableParserCache was deprecated, set $wgParserCacheType to CACHE_NONE
	instead if you want to disable the parser cache.
	* New-style continuation is now the default for API action=continue. Clients may
	use the 'rawcontinue' parameter to receive raw query-continue data, but the
	new style is encouraged as it's harder to implement incorrectly.
	* Deprecated API formats dump and wddx have been completely removed.
	* (T7645) The "Signature" button on the edit toolbar is now hidden by default
	in non-talk namespaces. A new configuration variable,
	$wgExtraSignatureNamespaces, controls in which subject (non-talk) namespaces
	the "Signature" button on the edit toolbar will be displayed.
	* $wgResourceLoaderUseESI was deprecated and removed. This was an experimental
	feature that was never enabled by default.
	* $wgResourceLoaderExperimentalAsyncLoading was deprecated and removed.
	This experimental feature was never enabled by default and is obsolete as of
	MediaWiki 1.26, in where ResourceLoader became fully asynchronous.
	* $wgMasterWaitTimeout was removed (deprecated in 1.24).
	* Fields in ParserOptions are now private. Use the accessors instead.
	* Custom LESS functions (defined via $wgResourceLoaderLESSFunctions or
	in extension.json) have been removed, after being deprecated in 1.24.
	* $wgAlwaysUseTidy has been removed.
	* ResetSessionID hook has been removed. Nothing seems to use it.
	* Certain AuthPlugin methods are deprecated in favor of new hooks:
	** AuthPlugin::initUser() is replaced by LocalUserCreated.
	** AuthPlugin::updateUser() is replaced by UserLoggedIn.
	** AuthPlugin::updateExternalDB() is replaced by the existing UserSaveSettings.
	** AuthPlugin::updateExternalDBGroups() is replaced by UserGroupsChanged.
	** AuthPluginUser::isHidden() is replaced by UserIsHidden.
	** AuthPluginUser::isLocked() is replaced by UserIsLocked.
	* The UserRights hook is deprecated in favor of the new UserGroupsChanged hook.
	* AuthPlugin::initUser() and AuthPlugin::updateUser() should no longer replace
	the passed User object.
	* $wgBlockAllowsUTEdit is now set to true by default. This allows
	blocked users to edit their talk pages unless explicitly disabled
	when they are being blocked.

	=== New features in 1.26 ===
	* (T51506) Now action=info gives estimates of actual watchers for a page.
	See $wgRCMaxAge, $wgWatchersMaxAge and $wgUnwatchedPageSecret
	to learn how to configure if needed.
	* Change tags can now be hidden in the interface by disabling the associated
	"tag-<id>" interface message.
	* ':' (colon) is now invalid in usernames for new accounts. Existing accounts
	are not affected.
	* Added a new hook, 'LogException', to log exceptions in nonstandard ways.
	* Revive the 'SpecialSearchResultsAppend' hook which occurs after the list of
	search results are rendered. The initial use case is to append a "give us
	feedback" link beneath the search results.
	* Added a new hook, 'RejectParserCacheValue', which allows extensions to
	reject an otherwise-successful parser cache lookup. The intent is to allow
	extensions to manage the eviction of archaic HTML output from the cache.
	* (T68699) The expiration of the UserID and Token login cookies
	($wgExtendedLoginCookieExpiration) can be configured independently of the
	expiration of all other cookies ($wgCookieExpiration).
	* (T50519) Support for generating JPEG/PNG thumbnails from WebP images added
	if ImageMagick is used as image scaler ($wgUseImageMagick = true). Uploading
	of WebP images still disabled by default. Add $wgFileExtensions[] =
	'webp'; to LocalSettings.php to enable uploading of WebP images.
	* Added new hooks 'EnhancedChangesListModifyLineData' &
	'EnhancedChangesListModifyBlockLineData', to modify the data used to build
	lines in enhanced recentchanges and watchlist.
	* Caches that need purging ability now use the WANObjectCache interface.
	This corresponds to a new $wgMainWANCache setting, which defaults to using
	the $wgMainCacheType settings.
	* Callers needing fast light-weight data stores use $wgMainStash to select
	the store type from $wgObjectCaches. The default is the local database.
	* Interface message overrides in the MediaWiki namespace will now be cached in
	memcached and APC (if available), rather than memcached and local files.
	* Added a new hook, 'RandomPageQuery', to allow modification of the query used
	by Special:Random to select random pages.
	* $wgTransactionalTimeLimit was added, which controls the request time limit
	for potentially slow POST requests that need to be as atomic as possible.
	* ResourceLoader now loads all scripts asynchronously. The top-queue and
	startup modules are no longer synchronously loaded.
	* 'mediawiki.ui.button' styles are no longer unconditionally loaded on every
	page. During the deprecation period, the styles will only be loaded on pages
	which contain 'mw-ui-button' in their HTML. Starting in 1.28, the styles will
	only be loaded if explicitly required.
	* If search returns zero results and current search engine has a "did you mean"
	suggestion, results for suggestion will be shown. Can be disabled by setting
	$wgSearchRunSuggestedQuery to false.
	* Added several JavaScript libraries for uploading files to MediaWiki
	from the client-side. See documentation for mw.Upload and its
	subclasses for more information.
	* Added OOUI dialogs and layout for file upload interfaces. See
	documentation for mw.Upload.Dialog, mw.Upload.BookletLayout and its
	subclasses for more information.

	=== extension.json changes in 1.26 ===
	* (T99344) The extension.json schema is now versioned. All extensions
	and skins should set a "manifest_version" property corresponding to
	the schema version they were written for. The only supported version
	currently is "1".
	* (T102523) The error message if a non-array attribute is set was improved.
	* (T107646) Configuration settings can now specify how they should be merged,
	which is necessary for arrays using integer keys.
	* (T110389) Adding namespaces through extension.json now actually works
	* $wgNamespaceProtection can now be set in extension.json.
	* $wgCapitalLinkOverrides can now be set in extension.json.
	* (T97186) Extensions using a custom prefix for their configuration settings
	can now set a "_prefix" key to override the default of "wg".
	* (T99084) Extensions can now specify what MediaWiki core versions they
	depend upon.
	* (T105236) The extension.json schema now validates custom classes in
	the "ResourceModules" property properly.

	==== New external libraries ====
	* Added composer/semver v1.0.0.
	* Added mediawiki/at-ease v1.1.0.
	* Added wikimedia/assert v0.2.2.
	* Added wikimedia/ip-set v1.0.1.
	* Added wikimedia/wrappedstring v2.0.0.

	==== Removed and replaced external libraries ====
	* Replaced leafo/lessphp v0.5.0 with oyejorge/less.php v1.7.0.9.

	=== Bug fixes in 1.26 ===
	* (T53283) load.php sometimes sends 304 response without full headers
	* (T65198) Talk page tabs now have a "rel=discussion" attribute
	* (T98841) {{msgnw:}} now preserves comments even when subst: is not used.
	* (T104142) $wgEmergencyContact and $wgPasswordSender now use their default
	value if set to an empty string.

	=== Action API changes in 1.26 ===
	* New-style continuation is now the default for action=continue. Clients may
	use the 'rawcontinue' parameter to receive raw query-continue data, but the
	new style is encouraged as it's harder to implement incorrectly.
	* Deprecated API formats dump and wddx have been completely removed.
	* API action=query&list=tags: The displayname can now be boolean false if the
	tag is meant to be hidden from user interfaces.
	* action=import no longer allows both the namespace= and rootpage= parameters
	to be set. If they are both set, the value of rootpage= will be ignored.
	* prop=revision output in enum mode is now sorted by timestamp rather than
	revision ID. This usually won't make any difference.
	* (T102645) Namespace list from meta=siteinfo&siprop=namespaces is now an array
	with formatversion=2.
	* Various other output from meta=siteinfo will now always be arrays instead of
	sometimes being numerically-indexed objects with formatversion=2.
	* When errors about users being blocked are returned, they now include
	information about the relevant block.
	* (T99926) list=random has higher limits, in line with other API modules.
	* list=random's rnredirect parameter is deprecated in favor of a new
	rnfilterredir parameter that also allows for listing both redirects and
	non-redirects.
	* list=random now supports continuation.
	* API responses to GET requests may now include ETag and Last-Modified headers,
	and will honor corresponding If-None-Match and If-Modified-Since on such
	requests.

	=== Action API internal changes in 1.26 ===
	* New metadata item ApiResult::META_KVP_MERGE to allow for merging the KVP key
	into the value when the value is an assoc.
	* API action modules may now provide values for the RFC 7232 ETag and
	Last-Modified headers. The API will check these against If-None-Match and
	If-Modified-Since request headers on GET requests and avoid executing the
	module when appropriate.

	=== Languages updated in 1.26 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Phabricator reports.

	* Languages added:
	** ase (American sign language), thanks to translator Icemandeaf
	** dty (डोटेली/Doteli), thanks to translators जनक राज भट्ट, बिप्लब आनन्द,
	मेश सिंह बोहरा, and राम प्रसाद जोशी
	** luz (لئری دوٙمینی / Southern Luri)
	** olo (Livvinкarjala / Livvi-Karelian), thanks to translators Denö, Hiloin
	Natoi, Ilja.mos, and Mashoi7

	=== Other changes in 1.26 ===
	* ChangeTags::tagDescription() will return false if the interface message
	for the tag is disabled.
	* Added PageHistoryPager::doBatchLookups hook.
	* Added $wikiId parameter to FormatAutocomments hook.
	* Added ParserCacheSaveComplete to ParserCache
	* supportsDirectEditing and supportsDirectApiEditing methods added to
	ContentHandler, to provide a way for ApiEditPage and EditPage to check
	if direct editing of content is allowed. These methods return false,
	by default for the ContentHandler base class and true for TextContentHandler
	and it's derivative classes (everything in core). For Content types that
	do not support direct editing, an alternative mechanism should be provided
	for editing, such as action overrides or specific api modules.
	* mediaWiki.confirmCloseWindow now returns an object of functions, instead of
	one function. The callback can't be called directly any more. The callback
	function is replaced with confirmCloseWindow.release().
	* BREAKING CHANGE: Added an optional ResouceLoaderContext parameter to
	ResourceLoaderModule::getDependencies(). Extension classes that override that
	method should be updated. If they aren't updated, PHP Strict standards
	warnings will appear when E_STRICT error reporting is enabled. Note: in the
	near future, this parameter will probably become non-optional.
	* Removed maintenance script deleteImageMemcached.php.
	* MWFunction::newObj() was removed (deprecated in 1.25).
	ObjectFactory::getObjectFromSpec() should be used instead.
	* The parser will no longer randomize the string it uses to mark the place of
	items that were stripped during parsing. It will use a fixed string instead.
	This causes the parser to re-use the regular expressions it uses to search
	and replace markers rather than generate novel expressions on each parse.
	Re-using regular expressions will improve performance on HHVM and the
	forthcoming PHP 7. The interfaces changes accompanying this change are:
	- Parser::getRandomString() and Parser::uniqPrefix() have been deprecated.
	- The $uniq_prefix argument for Parser::extractTagsAndParams() and the
	$prefix argument for StripState::_construct() are deprecated and their
	value is ignored.
	* wfSuppressWarnings() and wfRestoreWarnings() were split into a separate
	library, mediawiki/at-ease, and are now deprecated. Callers should use
	MediaWiki\suppressWarnings() and MediaWiki\restoreWarnings() directly.
	* The Block class constructor now takes an associative array of parameters
	instead of many optional positional arguments. Calling the constructor the old
	way will issue a deprecation warning.
	* The jquery.mwExtension module was deprecated.
	* $wgSpecialPageGroups was removed (deprecated in 1.21).
	* SpecialPageFactory::setGroup was removed (deprecated in 1.21).
	* SpecialPageFactory::getGroup was removed (deprecated in 1.21).
	* DatabaseBase::ignoreErrors() is now protected.
	* BREAKING CHANGE: mediawiki.legacy.ajax has been removed, following
	a lengthy deprecation period.
	* The ScopedPHPTimeout class was removed.
	* Removed maintenance script fixSlaveDesync.php.
	* Watchlist tokens, SpecialResetTokens, and User::getTokenFromOption()
	are deprecated. Applications using those can work via the OAuth
	extension instead. New tokens types should not be added.
	* DatabaseBase::errorCount() was removed (unused).
	* $wgDeferredUpdateList was removed.
	* DeferredUpdates::addHTMLCacheUpdate() was removed.

	This is a security and maintenance release of the MediaWiki 1.25 branch.

	=== Changes since 1.25.3 ===
	* (T117899) SECURITY: $wgArticlePath can no longer be set to relative paths
	that do not begin with a slash. This enabled trivial XSS attacks.
	Configuration values such as "http://my.wiki.com/wiki/$1" are fine, as are

	* (T114606) mw.notify was not correctly fixed to the page if
	initialized while not at the top of the page.

	== MediaWiki 1.25.3 ==

	This is a security and maintenance release of the MediaWiki 1.25 branch.

	=== Changes since 1.25.2 ===

	* (T98975) Fix having multiple callbacks for a single hook.
	* (T107632) maintenance/refreshLinks.php did not always remove all links
	pointing to nonexistent pages.
	* (T104142) $wgEmergencyContact and $wgPasswordSender now use their default
	value if set to an empty string.

	== MediaWiki 1.25.2 ==

	This is a security and maintenance release of the MediaWiki 1.25 branch.

	=== Changes since 1.25.1 ===

	* (T94116) SECURITY: Compare API watchlist token in constant time
	* (T97391) SECURITY: Escape error message strings in thumb.php
	* (T106893) SECURITY: Don't leak autoblocked IP addresses on
	Special:DeletedContributions
	* (T102562) Fix InstantCommons parameters to handle the new HTTPS-only
	policy of Wikimedia Commons.
	* (T100767) Setting a configuration setting for skin or extension to
	false in LocalSettings.php was not working.
	* (T100635) API action=opensearch json output no longer breaks when
	$wgDebugToolbar is enabled.
	* (T102522) Using an extension.json or skin.json file which has
	a "manifest_version" property for 1.26 compatability will no longer
	trigger warnings.
	* (T86156) Running updateSearchIndex.php will not throw an error as
	page_restrictions has been added to the locked table list.
	* Special:Version would throw notices if using SVN due to an incorrectly
	named variable. Add an additional check that an index is defined.

	== MediaWiki 1.25.1 ==

	This is a bug fix release of the MediaWiki 1.25 branch.

	=== Changes since 1.25 ===
	* (T100351) Fix syntax errors in extension.json of ConfirmEdit extension

	== MediaWiki 1.25.0 ==

	=== Configuration changes in 1.25 ===
	* $wgPageShowWatchingUsers was removed.
	* $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
	* $wgAntiLockFlags was removed.
	* $wgJavaScriptTestConfig was removed.
	* Edit tokens returned from User::getEditToken may change on every call. Token
	validity must be checked by passing the user-supplied token to
	User::matchEditToken rather than by testing for equality with a
	newly-generated token.
	* (T74951) The UserGetLanguageObject hook may be passed any IContextSource
	for its $context parameter. Formerly it was documented as receiving a
	RequestContext specifically.
	* Profiling was restructured and $wgProfiler now requires an 'output' parameter.
	See StartProfiler.sample for details.
	* $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
	might be a flash policy directive configurable.
	* ApiOpenSearch now supports XML output. The OpenSearchXml extension should no
	longer be used. If extracts and page images are desired, the TextExtracts and
	PageImages extensions are required.
	* $wgOpenSearchTemplate is deprecated in favor of $wgOpenSearchTemplates.
	* Edits are now prepared via AJAX as users type edit summaries. This behavior
	can be disabled via $wgAjaxEditStash.
	* (T46740) The temporary option $wgIncludejQueryMigrate was removed, along
	with the jQuery Migrate library, as indicated when this option was provided in
	MediaWiki 1.24.
	* ProfilerStandard and ProfilerSimpleTrace were removed. Make sure that any
	StartProfiler.php config is updated to reflect this. Xhprof is available
	for zend/hhvm. Also, for hhvm, one can consider using its xenon profiler.
	* Default value of $wgSVGConverters['rsvg'] now uses the 'rsvg-convert' binary
	rather than 'rsvg'.
	* Default value of $wgSVGConverters['ImageMagick'] now uses transparent
	background with white fallback color, rather than just white background.
	* MediaWikiBagOStuff class removed, make sure any object cache config
	uses SqlBagOStuff instead.
	* The 'daemonized' flag must be set to true in $wgJobTypeConf for any redis
	job queues. This means that mediawiki/services/jobrunner service has to
	be installed and running for any such queues to work.
	* $wgAutopromoteOnce no longer supports the 'view' event. For keeping some
	compatibility, any 'view' event triggers will still trigger on 'edit'.
	* $wgExtensionDirectory was added for when your extensions directory is
	somewhere other than $IP/extensions (as $wgStyleDirectory does with the skins
	directory).

	=== New features in 1.25 ===
	* (T64861) Updated plural rules to CLDR 26. Includes incompatible changes
	for plural forms in Russian, Prussian, Tagalog, Manx and several languages
	that fall back to Russian.
	* (T60139) ResourceLoaderFileModule now supports language fallback
	for 'languageScripts'.
	* Added a new hook, "ContentAlterParserOutput", to allow extensions to modify
	the parser output for a content object before links update.
	* (T37785) Enhanced recent changes and extended watchlist are now default.
	Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
	and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions
	* (T69341) SVG images will no longer be base64-encoded when being embedded
	in CSS. This results in slight size increase before gzip compression (due to
	percent-encoding), but up to 20% decrease after it.
	* Update jStorage to v0.4.12.
	* MediaWiki now natively supports page status indicators: icons (or short text
	snippets) usually displayed in the top-right corner of the page. They have
	been in use on Wikipedia for a long time, implemented using templates and CSS
	absolute positioning.
	- Basic wikitext syntax:
	<indicator name="foo">[[File:Foo.svg\|20px]]</indicator>
	- Usage instructions:
	https://www.mediawiki.org/wiki/Help:Page_status_indicators
	- Adjusting custom skins to support indicators:
	https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
	* Edit tokens may now be time-limited: passing a maximum age to
	User::matchEditToken will reject any older tokens.
	* The debug logging internals have been overhauled, and are now using the
	PSR-3 interfaces.
	* Update CSSJanus to v1.1.1.
	* Update lessphp to v0.5.0.
	* Added a hook, "ApiOpenSearchSuggest", to allow extensions to provide extracts
	and images for ApiOpenSearch output. The semantics are identical to the
	"OpenSearchXml" hook provided by the OpenSearchXml extension.
	* PrefixSearchBackend hook now has an $offset parameter. Combined with $limit,
	this allows for pagination of prefix results. Extensions using this hook
	should implement supporting behavior. Not doing so can result in undefined
	behavior from API clients trying to continue through prefix results.
	* Update jQuery from v1.11.1 to v1.11.3.
	* External libraries installed via composer will now be displayed
	on Special:Version in their own section. Extensions or skins that are
	installed via composer will not be shown in this section as it is assumed
	they will add the proper credits to the skins or extensions section. They
	can also be accessed through the API via the new siprop=libraries to
	ApiQuerySiteinfo.
	* Update QUnit from v1.14.0 to v1.16.0.
	* Update Moment.js from v2.8.3 to v2.8.4.
	* Special:Tags now allows for manipulating the list of user-modifiable change
	tags.
	* Added 'managetags' user right and 'ChangeTagCanCreate', 'ChangeTagCanDelete',
	and 'ChangeTagCanCreate' hooks to allow for managing user-modifiable change
	tags.
	* Added 'ChangeTagsListActive' hook, to separate the concepts of "defined" and
	"active" formerly conflated by the 'ListDefinedTags' hook.
	* Added TemplateParser class that provides a server-side interface to cachable
	dynamically-compiled Mustache templates (currently uses lightncandy library).
	* Clickable anchors for each section heading in the content are now generated
	and appear in the gutter on hovering over the heading.
	* Added 'CategoryViewer::doCategoryQuery' and 'CategoryViewer::generateLink'
	hooks to allow extensions to override how links to pages are rendered within
	NS_CATEGORY
	* (T19665) Special:WantedPages only lists page which having at least one red
	link pointing to it.
	* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
	used for conditional registration of API modules.
	* New hook 'EnhancedChangesList::getLogText' to alter, remove or add to the
	links of a group of changes in EnhancedChangesList.
	* A full interface for StatsD metric reporting has been added to the context
	interface, reachable via IContextSource::getStats().
	* Move the jQuery Client library from being mastered in MediaWiki as v0.1.0 to a
	proper, published library, which is now tagged as v1.0.0.
	* A new message (defaulting to blank), 'editnotice-notext', can be shown to
	users when they are editing if no edit notices apply to the page being edited.
	* (T94536) You can now make the sitenotice appear to logged-in users only by
	editing MediaWiki:Anonnotice and replacing its content with "". Setting it to
	"-" (default) will continue disable it and fallback to MediaWiki:Sitenotice.
	* Modifying the tagging of a revision or log entry is now available via
	Special:EditTags, generally accessed via the revision-deletion-like interface
	on history pages and Special:Log is likely to be more useful.
	* Added 'applychangetags' and 'changetags' user rights.
	* (T35235) LogFormatter subclasses are now responsible for formatting the
	parameters for API log event output. Extensions should implement the new
	getParametersForApi() method in their log formatters.

	==== External libraries ====
	* MediaWiki now requires certain external libraries to be installed. In the past
	these were bundled inside the Git repository of MediaWiki core, but now they
	need to be installed separately. For users using the tarball, this will be
	taken care of and no action will be required. Users using Git will either need
	to use composer to fetch dependencies or use the mediawiki/vendor repository
	which includes all dependencies for MediaWiki core and ones used in Wikimedia
	deployment. Detailed instructions can be found at:
	https://www.mediawiki.org/wiki/Download_from_Git#Fetch_external_libraries
	* The following libraries are now required:
	** psr/log
	This library provides the interfaces set by the PSR-3 standard
	(http://www.php-fig.org/psr/psr-3/) which are used by MediaWiki internally
	via the MediaWiki\Logger\LoggerFactory class.
	See the structured logging RfC
	<https://www.mediawiki.org/wiki/Requests_for_comment/Structured_logging>
	for more background information.
	** cssjanus/cssjanus
	This library was formerly bundled with MediaWiki core and has been removed.
	It automatically flips CSS for RTL support.
	** leafo/lessphp
	This library was formerly bundled with MediaWiki core and has been removed.
	It compiles LESS files into CSS.
	** wikimedia/cdb
	This library was formerly a part of MediaWiki core, and has been moved into a
	separate library. It provides CDB functions which are used in the Interwiki
	and Localization caches. More information about the library can be found at
	https://www.mediawiki.org/wiki/CDB.
	** liuggio/statsd-php-client
	This library provides a StatsD client API for logging application metrics to
	a remote server.

	=== Bug fixes in 1.25 ===
	* (T73003) No additional code will be generated to try to load CSS-embedded
	SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
	* (T69021) On Special:BookSources, corrected validation of ISBNs (both
	10- and 13-digit forms) containing "X".
	* Page moving was refactored into a MovePage class. As part of that:
	** The AbortMove hook was removed.
	** MovePageIsValidMove is for extensions to specify whether a page
	cannot be moved for technical reasons, and should not be overridden.
	** MovePageCheckPermissions is for checking whether the given user is
	allowed to make the move.
	** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
	** Title::moveTo() was deprecated. Use the MovePage class instead.
	** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
	and MovePage::checkPermissions().
	* (T18530) Multiple autocomments are now formatted in an edit summary.
	* (T70361) Autocomments containing "/*" are parsed correctly.
	* The Special:WhatLinksHere page linked from 'Number of redirects to this page'
	on action=info about a file page does not list file links anymore.
	* (T78637) Search bar is not autofocused unless it is empty so that proper
	scrolling using arrow keys is possible.
	* (T50853) Database::makeList() modified to handle 'NULL' separately when
	building IN clause
	* (T85192) Captcha position modified in Usercreate template. As a result:
	** extrafields parameter added to Usercreate.php to insert additional data
	** 'extend' method added to QuickTemplate to append additional values to any
	field of data array
	* (T86974) Several Title methods now load from the database when necessary
	(instead of returning incorrect results) even when the page ID is known.
	* (T74070) Duplicate search for archived files on file upload now omits the
	extension.
	This requires the fa_sha1 field being populated.
	* Removed rel="archives" from the "View history" link, as it did not pass
	HTML validation.
	* $wgUseTidy is now set when parserTests are run with the tidy option to match
	output on wiki.
	* (T37472) update.php will purge ResourceLoader cache unless --nopurge is passed
	to it.
	* (T72109) mediawiki.language should respect $wgTranslateNumerals in
	convertNumber().

	=== Action API changes in 1.25 ===
	* (T67403) XML tag highlighting is now only performed for formats
	"xmlfm" and "wddxfm".
	* action=paraminfo supports generalized submodules (modules=query+value),
	querymodules and formatmodules are deprecated
	* action=paraminfo no longer outputs descriptions and other help text by
	default. If needed, it may be requested using the new 'helpformat' parameter.
	* action=help has been completely rewritten, and outputs help in HTML
	rather than plain text.
	* Hitting api.php without specifying an action now displays only the help for
	the main module, with links to submodule help.
	* API help is no longer displayed on errors.
	* 'uselang' is now a recognized API parameter; "uselang=user" may be used to
	explicitly select the language from the current user's preferences, and
	"uselang=content" may be used to select the wiki's content language.
	* Default output format for the API is now jsonfm.
	* Simplified continuation will return a "batchcomplete" property in the result
	when a batch of pages is complete.
	* Pretty-printed HTML output now has nicer formatting and (if available)
	better syntax highlighting.
	* Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
	list=alldeletedrevisions.
	* prop=revisions will gracefully continue when given too many revids or titles,
	rather than just ignoring the extras.
	* prop=revisions will no longer die if rvcontentformat doesn't match a
	revision's content model; it will instead warn and omit the content.
	* If the user has the 'deletedhistory' right, action=query's revids parameter
	will now recognize deleted revids.
	* prop=revisions may be used as a generator, generating revids.
	* (T68776) format=json results will no longer be corrupted when
	$wgMangleFlashPolicy is in effect. format=php results will cleanly return an
	error instead of returning invalid serialized data.
	* Generators may now return data for the generated pages when used with
	action=query.
	* Query page data for generator=search and generator=prefixsearch will now
	include an "index" field, which may be used by the client for sorting the
	search results.
	* ApiOpenSearch now supports XML output.
	* ApiOpenSearch will now output descriptions and URLs as array indexes 2 and 3
	in JSON format.
	* (T76051) list=tags will now continue correctly.
	* (T76052) list=tags can now indicate whether a tag is defined.
	* (T75522) list=prefixsearch now supports continuation
	* (T78737) action=expandtemplates can now return page properties.
	* (T78690) list=allimages now accepts multiple pipe-separated values
	for the 'aimime' parameter.
	* prop=info with inprop=protections will now return applicable protection types
	with the 'restrictiontypes' key.
	* (T85417) When resolving redirects, ApiPageSet will now add the targets of
	interwiki redirects to the list of interwiki titles.
	* (T85417) When outputting the list of redirect titles, a 'tointerwiki'
	property (like the existing 'tofragment' property) will be set.
	* Added action=managetags to allow for managing the list of
	user-modifiable change tags. Actually modifying the tagging of a revision or
	log entry is not implemented yet.
	* list=tags has additional properties to indicate 'active' status and tag
	sources.
	* siprop=libraries was added to ApiQuerySiteinfo to list installed external
	libraries.
	* (T88010) Added action=checktoken, to test a CSRF token's validity.
	* (T88010) Added intestactions to prop=info, to allow querying of
	Title::userCan() via the API.
	* Default type param for query list=watchlist and list=recentchanges has
	been changed from all types (e.g. including 'external') to 'edit\|new\|log'.
	* Added formatversion to format=json. Still "experimental" as further changes
	to the output formatting might still be made.
	* (T73020) Log event details are now always under a 'params' subkey for
	list=logevents, and a 'logparams' subkey for list=watchlist and
	list=recentchanges.
	* Log event details are changing formatting:
	* block events now report flags as an array rather than as a comma-separated
	list.
	* patrol events now report the 'auto' flag as a boolean (absent/empty string
	for BC formats) rather than as an integer.
	* rights events now report the old and new group lists as arrays rather than
	as comma-separated lists.
	* merge events use new-style formatting.
	* delete/event and delete/revision events use new-style formatting.
	* The root node and various other nodes will now always be an object in formats
	such as json that distinguish between arrays and objects.
	* Except for action=opensearch where the spec requires an array.

	=== Action API internal changes in 1.25 ===
	* ApiHelp has been rewritten to support i18n and paginated HTML output.
	Most existing modules should continue working without changes, but should do
	the following:
	* Add an i18n message "apihelp-{$moduleName}-description" to replace
	getDescription().
	* Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
	to replace getParamDescription(). If necessary, the settings array returned
	by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
	message.
	* Implement getExamplesMessages() to replace getExamples().
	* Modules with submodules (like action=query) must have their submodules
	override ApiBase::getParent() to return the correct parent object.
	* The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
	and will have no effect for modules using i18n messages. Use
	'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
	* Api formatters will no longer be asked to display the help screen on errors.
	* ApiMain::getCredits() was removed. The credits are available in the
	'api-credits' i18n message.
	* ApiFormatBase has been changed to support i18n and syntax highlighting via
	extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
	has been removed.
	* ApiFormatBase now always buffers. Output is done when
	ApiFormatBase::closePrinter is called.
	* Much of the logic in ApiQueryRevisions has been split into
	ApiQueryRevisionsBase.
	* The 'revids' parameter supplied by ApiPageSet will now count deleted
	revisions as "good" if the user has the 'deletedhistory' right. New methods
	ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
	provided to access just the live or just the deleted revids.
	* Added ApiPageSet::setGeneratorData() and ApiPageSet::populateGeneratorData()
	to allow generators to include data in the action=query result.
	* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
	used for conditional registration of API modules.
	* Added ApiBase::lacksSameOriginSecurity() to allow modules to easily check if
	the current request was sent with the 'callback' parameter (or any future
	method that breaks the same-origin policy).
	* Profiling methods in ApiBase are deprecated and no longer need to be called.
	* ApiResult was greatly overhauled. See inline documentation for details.
	* ApiResult will automatically convert objects to strings or arrays (depending
	on whether a __toString() method exists on the object), and will refuse to
	add unsupported value types.
	* An informal interface, ApiSerializable, exists to override the default
	object conversion.
	* ApiResult/ApiFormatBase "raw mode" is deprecated.
	* ApiFormatXml now assumes defaults and so on instead of throwing errors when
	metadata isn't set.
	* (T35235) LogFormatter subclasses are now responsible for formatting log event
	parameters for the API.
	* Many modules have changed result data formats. While this shouldn't affect
	clients not using the experimental formatversion=2, code using
	ApiResult::getResultData() without the transformations for backwards
	compatibility may need updating, as will code that wasn't following the old
	conventions for API boolean output.
	* The following methods have been deprecated and may be removed in a future
	release:
	* ApiBase::getDescription
	* ApiBase::getParamDescription
	* ApiBase::getExamples
	* ApiBase::makeHelpMsg
	* ApiBase::makeHelpArrayToString
	* ApiBase::makeHelpMsgParameters
	* ApiBase::getModuleProfileName
	* ApiBase::profileIn
	* ApiBase::profileOut
	* ApiBase::safeProfileOut
	* ApiBase::getProfileTime
	* ApiBase::profileDBIn
	* ApiBase::profileDBOut
	* ApiBase::getProfileDBTime
	* ApiBase::getResultData
	* ApiFormatBase::setUnescapeAmps
	* ApiFormatBase::getWantsHelp
	* ApiFormatBase::setHelp
	* ApiFormatBase::formatHTML
	* ApiFormatBase::setBufferResult
	* ApiFormatBase::getDescription
	* ApiFormatBase::getNeedsRawData
	* ApiMain::setHelp
	* ApiMain::reallyMakeHelpMsg
	* ApiMain::makeHelpMsgHeader
	* ApiResult::setRawMode
	* ApiResult::getIsRawMode
	* ApiResult::getData
	* ApiResult::setElement
	* ApiResult::setContent
	* ApiResult::setIndexedTagName_recursive
	* ApiResult::setIndexedTagName_internal
	* ApiResult::setParsedLimit
	* ApiResult::beginContinuation
	* ApiResult::setContinueParam
	* ApiResult::setGeneratorContinueParam
	* ApiResult::endContinuation
	* ApiResult::size
	* ApiResult::convertStatusToArray
	* ApiQueryImageInfo::getPropertyDescriptions
	* ApiQueryLogEvents::addLogParams
	* The following classes have been deprecated and may be removed in a future
	release:
	* ApiQueryDeletedrevs

	=== Languages updated in 1.25 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Bugzilla reports.

	* Languages added:
	** awa (अवधी / Awadhi), thanks to translator 1AnuraagPandey;
	** bgn (بلوچی رخشانی / Western Balochi), thanks to translators
	Baloch Afghanistan, Ibrahim khashrowdi and Rachitrali;
	** ses (Koyraboro Senni), thanks to translator Songhay.
	* (T66440) Kazakh (kk) wikis should no longer forcefully reset the user's
	interface language to kk where unexpected.
	* The Chinese conversion table was substantially updated to fix a lot of
	bugs and ensure better reading experience for different variants.

	=== Other changes in 1.25 ===
	* (T45591) Links to MediaWiki.org translatable help were added to indicators,
	mostly in special pages. Local custom target titles can be placed in the
	relevant '(namespace-X\|action name\|special page name)-helppage' system
	message. Extensions can use the addHelpLink() function to do the same.
	* The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
	removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
	migration guide for creators and users of custom skins that relied on it.
	* Javascript variables 'wgFileCanRotate' and 'wgFileExtensions' now only
	available on Special:Upload.
	* (T58257) Set site logo from mediawiki.skinning.interface module instead of
	inline styles in the HTML.
	* Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
	* Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
	* Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
	* Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
	* Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since
	1.20)
	* Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
	since 1.20)
	* Removed 'async' parameter from the mw.Api#getCategories() method. (deprecated
	since 1.20)
	* Removed 'jquery.json' module. (deprecated since 1.24)
	Use the 'json' module and global JSON object instead.
	* Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
	Also, the former will now throw an MWException if called with one or more
	arguments.
	* Removed hitcounters and associated code.
	* The "temp" zone of the upload respository is now considered private. If it
	already exists (such as under the images/ directory), please make sure that
	the directory is not web readable (e.g. via a .htaccess file).
	* BREAKING CHANGE: In the XML dump format used by Special:Export and
	dumpBackup.php, the <model> and <format> tags now apprear before the <text>
	tag, instead of after the <text> and <sha1> tags.
	The new schema version is 0.10, the new schema URI is:
	https://www.mediawiki.org/xml/export-0.10.xsd
	* MWFunction::call() and MWFunction::callArray() were removed, having being
	deprecated in 1.22.
	* Deprecated the getInternalLinkAttributes, getInternalLinkAttributesObj,
	and getInternalLinkAttributes methods in Linker, and removed
	getExternalLinkAttributes method, which was deprecated in MediaWiki 1.18.
	* Removed Sites class, which was deprecated in 1.21 and replaced by
	SiteSQLStore.
	* Added wgRelevantArticleId to the client-side config, for use on special pages.
	* Deprecated the TitleIsCssOrJsPage hook. Superseded by the
	ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
	* Deprecated the TitleIsWikitextPage hook. Superseded by the
	ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
	* Changed parsing of variables in schema (.sql) files:
	** The substituted values are no longer parsed. (Formerly, several passes
	were made for each variable, so depending on the order in which variables
	were defined, variables might have been found inside encoded values. This
	is no longer the case.)
	** Variables are no longer string encoded when the /$var/ syntax is used.
	If string encoding is necessary, use the '{$var}' syntax instead.
	** Variable names must only consist of one or more of the characters
	"A-Za-z0-9_".
	** In source text of the form '{$A}'{$B}' or `{$A}`{$B}`, where variable A
	does not exist yet variable B does, the latter may not be replaced.
	However, this difference is unlikely to arise in practice.
	* (T67278) RFC, PMID, and ISBN "magic links" must be surrounded by non-word
	characters on both sides.
	* The FormatAutocomments hook will now receive $pre and $post as booleans,
	rather than as strings that must be prepended or appended to $comment.
	* (T30950, T31025) RFC, PMID, and ISBN "magic links" can no longer contain
	newlines; but they can contain   and other non-newline whitespace.
	* The 'mediawiki.action.edit' ResourceLoader module no longer generates the edit
	toolbar, which has been moved to a separate 'mediawiki.toolbar' module. If you
	relied on this behavior, update your scripts' dependencies.
	* HTMLForm's 'vform' display style has been separated to a subclass. Therefore:
	* HTMLForm::isVForm() is now deprecated.
	* You can no longer do this:
	$form = new HTMLForm( … );
	$form->setDisplayFormat( 'vform' ); // throws exception
	Instead, do this:
	$form = HTMLForm::factory( 'vform', … );
	* Deprecated Revision methods getRawUser(), getRawUserText() and
	getRawComment().
	* BREAKING CHANGE: mediawiki.user.generateRandomSessionId:
	The alphabet of the prior string returned was A-Za-z0-9 and now it is 0-9A-F
	* (T87504) Avoid serving SVG background-images in CSS for Opera 12, which
	renders them incorrectly when combined with border-radius or background-size.
	* Removed maintenance script dumpSisterSites.php.
	* DatabaseBase class constructors must be called using the array argument style.
	Ideally, DatabaseBase:factory() should be used instead in most cases.
	* Deprecated ParserOutput::addSecondaryDataUpdate and
	ParserOutput::getSecondaryDataUpdates.
	This is a hard deprecation, with getSecondaryDataUpdates returning an empty
	array and addSecondaryDataUpdate throwing an exception. These functions will
	be removed in 1.26, since they interfere with caching of ParserOutput objects.
	* Introduced new hook 'SecondaryDataUpdates' that allows extensions to inject
	custom updates.
	* Introduced new hook 'OpportunisticLinksUpdate' that allows extensions to
	perform updates when a page is re-rendered.
	* EditPage::attemptSave has been modified not to call handleStatus itself and
	instead just returns the Status object. Extension calling it should be aware
	of this.
	* Removed class DBObject. (unused since 1.10)
	* wfDiff() is deprecated.
	* The -m (maximum replication lag) option of refreshLinks.php was removed.
	It had no effect since MediaWiki 1.18 and should be removed from any cron
	jobs or similar scripts you may have set up.
	* (T85864) The following messages no longer support raw html: redirectto,
	thisisdeleted, viewdeleted, editlink, retrievedfrom, version-poweredby-others,
	retrievedfrom, thisisdeleted, viewsourcelink, lastmodifiedat, laggedslavemode,
	protect-summary-cascade
	* All BloomCache related code has been removed. This was largely experimental.
	* $wgResourceModuleSkinStyles no longer supports per-module local or remote
	paths. They can only be set for the entire skin.
	* Removed global function swap(). (deprecated since 1.24)
	* Deprecated the ".php5" file extension entry points and the $wgScriptExtension
	configuration variable. Refer to the ".php" files instead. If you want
	".php5" URLs to continue to work, set up redirects. In Apache, this can be
	done by enabling mod_rewrite and adding the following rules to your
	configuration:

	RewriteEngine On
	RewriteBase /
	RewriteRule ^(.*)\.php5 $1.php [R=301,L]

	* The global importScriptURI and importStylesheetURI functions, as well as the
	loadedScripts object, from wikibits.js (deprecated since 1.17) now emit
	warnings through mw.log.warn when accessed.

	* (bug T74834) Make 1.24 branch directly installable under PostgreSQL.

	== MediaWiki 1.24.0 ==

	=== Configuration changes in 1.24 ===
	* MediaWiki will no longer run if register_globals is enabled. It has been
	deprecated for 5 years now, and was removed in PHP 5.4. For more information
	about why, see <https://www.mediawiki.org/wiki/register_globals>.
	* MediaWiki now requires PHP's iconv extension. openSUSE users may need to
	install the php5-iconv package. Users of other systems may need to add
	extension=iconv.so to php.ini or recompile PHP without --without-iconv.
	* MediaWiki will no longer function if magic quotes are enabled. It has
	been deprecated for 5 years now, and was removed in PHP 5.4.
	* The server's canonical hostname is available as $wgServerName, which is
	exposed in both mw.config and ApiQuerySiteinfo.
	* Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
	for using the old schema of the page_props table, in case the respective
	schema update was not applied.
	* $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
	user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
	if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
	* $wgMasterWaitTimeout has been deprecated.
	* $wgDBClusterTimeout has been removed.
	* $wgProxyKey has been removed. It is no longer used by MediaWiki core.
	Ensure $wgSecretKey is set in LocalSettings.php.
	* $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
	contains an array of interwiki prefixes that should be treated as language
	prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
	to true).
	* $wgParserTestRemote has been removed.
	* $wgCountTotalSearchHits has been removed. If you're concerned about efficiency
	of search, you should use something like CirrusSearch instead of built in
	search.
	* Users in the 'sysop' group have access to Special:MergeHistory by default.
	* $wgFileStore was removed after having been deprecated in 1.17. Alternative
	configurations are $wgDeletedDirectory and $wgHashedUploadDirectory.
	* The deprecated $wgUseCommaCount variable has been removed.
	* $wgEnableSorbs and $wgSorbsUrl have been removed.
	* The UserCryptPassword and UserComparePassword hooks are no longer called.
	Any extensions using them must be updated to use the Password Hashing API.
	* $wgCompiledFiles has been removed.
	* $wgSortSpecialPages was removed, the listing on Special:SpecialPages is
	now always sorted.
	* $wgSpecialPages may now use callback functions as an alternative to plain
	class names. This allows more control over constructor parameters.
	* $wgHTCPMulticastAddress, $wgHTCPMulticastRouting and $wgHTCPPort were removed.
	* $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort
	and $wgRC2UDPPrefix have been removed.
	* The default password type for MediaWiki has been changed from MD5 to PBKDF2.
	Password hashes will automatically be updated as users log in. If necessary,
	the old MD5 hashing can be restored by changing $wgPasswordDefault to 'B'.
	In addition, there is a maintenance script wrapOldPassword.php that can wrap
	all passwords in PBKDF2 (or the hashing algorithm of your choice) if you don't
	want to wait for your users to log in.
	* $wgImportSources can now either be a regular array, or an associative map
	specifying subprojects on the interwiki map of the target wiki, or a mix of
	the two. Existing configurations will still work.
	* Users must be able to edit through a page's protection to be able to delete
	it.
	* The default thumb size ($wgDefaultUserOptions['thumbsize']) is now 300px, up
	from 180px. If you have altered the number of entries in $wgThumbLimits for
	your wiki, you may need to adjust your default user settings to compensate for
	the index change.
	* $wgDeferredUpdateList is now deprecated, you should use
	DeferredUpdates::addUpdate() instead.
	* $wgCanonicalLanguageLinks has been removed. Per Google recommendations, we
	will not send a rel=canonical pointing to a variant-neutral page, however
	we will send rel=alternate.
	* $wgResourceLoaderLESSFunctions has been deprecated and will be removed in the
	future.
	* $wgGoToEdit has been removed. Use the SpecialSearchNogomatch hook for similar
	functionality.

	=== New features in 1.24 ===
	* Added new hook WatchlistEditorBeforeFormRender, allowing subscribers to
	manipulate the list of pages and/or preload lots of data at once.
	* Added new argument &$link in hook WatchlistEditorBuildRemoveLine, allowing the
	link to the title to be changed.
	* Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
	WhatLinksHere entries.
	* Added a new hook, "ContentGetParserOutput", to customize parser output for
	a given content object.
	* Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
	* HTMLForm's HTMLTextField now supports the 'url' type.
	* HTMLForm fields may now be dynamically hidden based on the values of other
	fields in the form.
	* HTMLForm now supports multiple copies of an input field or set of input
	fields, e.g. the form may request "one or more usernames" without having to
	have the user enter delimited list of names into a text field.
	* Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
	the sidebar just before its display.
	* (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
	jquery.cookie so that getting/setting a cookie is syntactically and
	functionally similar to using the WebRequest::getCookie() and
	WebResponse::setcookie() methods.
	* (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
	$wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
	and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
	This option is turned off by default, and will be removed in MediaWiki 1.25.
	* (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
	* Changes to content typography (fonts, etc.). See
	https://www.mediawiki.org/wiki/Typography_refresh for further information.
	* WikitextContent will now render redirects with the expected "redirect"
	header, rather than as an ordered list. Code calling Article::viewRedirect
	can probably be changed to no longer special-case redirects.
	* Header font set to a serif font stack. See
	https://www.mediawiki.org/wiki/Typography_refresh for further information.
	* (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
	the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
	is only for page views, since this hook doesn't affect UserLogin, OAuth,
	CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
	overall design of the system.
	* (bug 17367) It is now possible to add pages to your watchlist from
	Special:UnwatchedPages without reloading the special page.
	* New methods setVolatile and isVolatile are added to PPFrame, so that
	extensions such as Cite.php can mark that their output is volatile and
	shouldn't be cached.
	* (bug 52817) Advanced search options are now saved on the search page itself,
	rather than in a dedicated pane in the preferences panel.
	* (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
	the Vector skin has gained a label that should make it more discoverable.
	* MWCryptHKDF added for fast, cryptographically secure random number generation
	that won't deplete openssl's entropy pool.
	* ResourceLoader: File modules can now provide a skip function that uses an
	inline feature test to bypass loading of the module.
	* (bug 20210) Special pages may now provide autocompletion of their subpage
	names in search suggestions. Right now the only useful implementation is in
	Special:Log, but more are to come.
	* Special:MostLinkedTemplates is no longer limited to transclusions from the
	Template namespace.
	* Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
	This works the same as 'remoteExtPath' but is relative to the skins/ folder
	instead of the extensions/ folder.
	* Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
	Exposed as module "json" with a skip function to optimise loading.
	* Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
	to 'name', to allow for the name to be localizable. 'name' should still be
	specified for backwards-compatibility and to define the path Special:Version
	uses to find extension license information.
	* Browser tests are now included to verify basic wiki functionality in developer
	environments. For details on running tests, see
	tests/browser/README.mediawiki.
	* Upgrade jStorage to v0.4.10.
	* {{!}} is now a magic word that produces the \| character. This removes the need
	for Template:! for purposes such as passing pipes inside of parameters.
	* (bug 20790) The block log snippet on Special:Contributions and while
	editing user and user talk pages now works for IP range blocks.
	* (bug 9360) Added ability to change the page language for MediaWiki pages using
	Special:PageLanguage. All pages are set to wiki language by default.
	The feature needs to be enabled with $wgPageLanguageUseDB=true and
	permission needs to be set for 'pagelang'.
	* Upgrade Moment.js to v2.8.3.
	* (bug 67042) Added support for the HTML5 <rtc> tag for East Asian typography.
	* Upgrade Sinon.JS to 1.10.3.
	* Added the es5-shim polyfill for older or non-compliant javascript engines.
	* Upgrade jQuery Cookie to v1.3.1.
	* (bug 20476) Add a "viewsuppressed" user right to be able to view
	suppressed content but not suppress it ("suppressrevision" right).
	* (bug 66440) The MediaWiki web installer will now allow you to choose the skins
	to enable (from the ones included in download tarball) and decide which one
	should be the default.
	* (bug 68085, 68802) Links like [[localInterwikiPrefix:languageCode:pageTitle]],
	where localInterwikiPrefix is a member of the $wgLocalInterwikis array, will
	no longer be displayed in the sidebar when $wgInterwikiMagic is true. In a
	similar way, links like [[localInterwikiPrefix:File:Image.png]] and
	[[localInterwikiPrefix:Category:Hello]] will now render as regular links, and
	will not include the file or add the page to the category.
	* New special page, MyLanguage, to redirect users to subpages with localised
	versions of a page. (Integrated from Extension:Translate)
	* MediaWiki now supports multiple password types, including bcrypt and PBKDF2.
	The default type can be changed with $wgPasswordDefault and the type
	configurations can be changed with $wgPasswordConfig.
	* Skins can now define custom styles for default ResourceLoader modules using
	the $wgResourceModuleSkinStyles global. See the Vector skin for examples.
	* (bug 4488) There is now a preference to watch pages where the user has
	rollbacked an edit by default.
	* (bug 15484) Users will now be redirected to the login page when they need to
	log in, rather than being shown a page asking them to log in and having to
	click another link to actually get to the login page.
	* A JsonContent and JsonContentHandler were added for extensions to extend.
	* (bug 35045) Redirects to sections will now update the URL in browser's address
	bar using the HTML5 History API. When [[Dog]] redirects to [[Animals#Dog]],
	the user will now see "Animals#Dog" in their browser instead of "Dog#Dog".
	* API token handling has been rewritten. Any API module using tokens will need
	to be updated. See the entry below under "Action API internal changes".
	* Added HTMLAutoCompleteSelectField.
	* Added a new hook, "SkinPreloadExistence", to allow extensions to add titles to
	link existence cache before the page is rendered.
	* Config::set() was moved to its own interface, MutableConfig.
	GlobalVarConfig::set() is now deprecated, does not implement MutableConfig.
	* A MutableConfig named HashConfig was added, that stores an array of
	configuration settings.
	* (bug 69418) A MultiConfig implementation was added that supports fallback
	to multiple Config instances.
	* Update CSSJanus to v1.1.0.
	* Added FormatJson::parse() returning status with result or localized error
	message
	* Added DeletedContribsPager::reallyDoQuery hook allowing extensions to data to
	Special:DeletedContributions
	* Added DeletedContributionsLineEnding hook allowing extensions to format
	Special:DeletedContributions lines
	* (T69525) You can now make MediaWiki speed up its thumbnail rendering by using
	intermediary thumbnails. $wgThumbnailBuckets must be set to a list of target
	thumbnail widths; when a new thumbnail needs to be rendered, MediaWiki will
	find the smallest bucket smaller than the original but larger than the target
	width + $wgThumbnailMinimumBucketDistance, and it will scale that thumbnail,
	rather than the original, down to the target size at greater speed in return
	for minor loss of fidelity.

	=== Bug fixes in 1.24 ===
	* (bug 50572) MediaWiki:Blockip should support gender
	* (bug 49116) Footer copyright notice is now always displayed in user language
	rather than content language (same as copyright notice for editing interface).
	* (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
	restriction was present in the parameters. Images with both the "frame"
	option and a size specification set will now always ignore the provided
	size and display an unscaled image, as the documentation has always
	claimed it would.
	* (bug 39035) Improved Vector skin performance by removing collapsibleNav,
	which used to collapse some sidebar elements by default.
	This removes -list id suffixes like p-lang-list: instead of using things like
	#p-lang-list, you can do #p-lang .body ul.
	* (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
	follow redirects to their target pages.
	* Parser now dies early if called recursively, instead of producing subtle bugs.
	* (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
	remaining page content.
	* (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
	in the file namespace and delete the file on the target page. It will still
	however delete the redirect page.
	* (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
	recover the original code of extension tags.
	* (bug 65757) MSSQL: Update script drops unnamed constraints to be prepared
	for future updates. Because it's doing so heuristically, it may fail or drop
	wrong constraints.
	* (bug 67870) wfShellExec() cuts off stdout at multiples of 8192 bytes.
	* $wgRunJobsAsync now works with private wikis (e.g. read requires login).
	* (bugs 57238, 65206) Blank pages can now be directly created.
	* (bug 69789) Title::getContentModel() now loads from the database when
	necessary instead of incorrectly returning the default content model.
	* (bug 69249) wfBaseConvert() now works around PHP Bug #50175 when using GMP.
	* (bug 57909) URLs in the externallinks table will no longer have certain
	characters decoded in the query string.
	* (bug 67368) LESS mixins like .background-image() correctly flip image
	references for RTL stylesheets now.

	=== Action API changes in 1.24 ===
	* action=parse API now supports prop=modules, which provides the list of
	ResourceLoader modules that should be used to enhance the parsed content.
	* action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
	field which is true if protocol-relative urls can be used to access
	a particular interwiki map entry.
	* list=logevents now provides logpage, which is the page ID from the
	logging table, if ids are requested and the user has the permissions.
	* action=edit now requires that appendtext, prependtext, or section=new be used
	when using the 'redirect' parameter, to prevent clients accidentally
	overwriting the target page with the content of the redirect.
	* list=logevents will now return an error if both letitle and leprefix are
	specified.
	* list=logevents has a new parameter, lenamespace, to allow filtering by
	namespace.
	* action=expandtemplates has a new parameter, prop, and a new output format.
	The old format is still used if prop isn't provided, but this is deprecated.
	* meta=userinfo can now return the count of unread pages on the watchlist.
	* list=watchlist can now filter by unread status.
	* The deprecated action=parse&prop=languageshtml has been removed.
	* (bug 48071) action=setnotificationtimestamp no longer throws PHP or database
	errors when no pages are given.
	* (bug 60734) Actions that use ApiPageSet (e.g. purge, watch,
	setnotificationtimestamp) will now include continuation information when
	using a generator.
	* Removed 'props' and 'errors' from action=paraminfo, as they have extremely
	limited use and are generally inaccurate, unmaintained, and impossible to
	properly maintain.
	* Formats dbg, dump, txt, wddx, and yaml are now deprecated.
	* action=paraminfo now indicates when a parameter is specifying a submodule.
	* The iwurl parameter to prop=iwlinks is deprecated in favor of iwprop=url, for
	parallelism with prop=langlinks.
	* All tokens should be fetched from action=query&meta=tokens; all other methods
	of fetching tokens are deprecated. The value needed for meta=tokens's 'type'
	parameter for each module is documented in the action=help output and is
	returned from action=paraminfo.
	* New action ClearHasMsg that can be used to clear HasMsg flag.
	* The cmstartsortkey and cmendsortkey parameters to list=categorymembers are
	deprecated in favor of cmstarthexsortkey and cmendhexsortkey.
	* (bug 63326) Add blockedtimestamp field to output of blockinfo property for
	the list=allusers and list=users modules.
	* prop=imageinfo no longer requires iiurlwidth to be set when using iiurlparam.
	* Added prop=linkshere, prop=fileusage, and prop=transcludedin, which are
	roughly equivalent to list=backlinks, list=imageusage, and list=embeddedin
	but can work on a list of titles (including titles from a generator).
	* prop=redirects can now filter returned redirects by namespace.

	=== Action API internal changes in 1.24 ===
	* Methods for handling continuation are added to ApiResult, so actions other
	than query that use generators can easily support continuation.
	* $wgAPIModules (and the related $wgAPIFormatModules, $wgAPIMetaModules,
	$wgAPIPropModules, and $wgAPIListModules settings) now allow API modules
	to be specified using a "module spec" array instead of a plain class name.
	A "module spec" is an associative array containing at least the 'class' key
	for the module's class, and optionally a 'factory' key for the factory
	function to use for the module. This is intended for extensions that want
	control over the instantiation of their API modules, to allow for proper
	dependency injection.
	* A new param type 'submodule' is available. Parameters of this type will take
	the list of valid values from the module's ApiModuleManager for the group
	corresponding to the parameter name.
	* The 'APIGetPossibleErrors' and 'APIGetResultProperties' hooks are no longer
	used.
	* API token handling has been rewritten. Any API module using tokens will need
	to be updated:
	* ApiBase::needsToken now returns a token type instead of boolean true when a
	token is needed. Returning true will throw an exception. See documentation
	of that method for details.
	* Information for the 'token' parameter is automatically set by ApiBase
	getFinalParams and getFinalParamDescription.
	* ApiBase::getTokenSalt has been removed.
	* The hooks APIQueryInfoTokens, APIQueryRevisionsTokens,
	APIQueryRecentChangesTokens, APIQueryUsersTokens, and
	ApiTokensGetTokenTypes are deprecated, but are still called to support
	backwards-compatible token access.
	* ApiBase::validateLimit and ApiBase::validateTimestamp are now protected.
	* ApiQueryRedirects was removed; prop=redirects is now implemented by
	ApiQueryBacklinksProp along with the newly-added prop modules.
	* The following methods have been deprecated and may be removed in a future
	release:
	* ApiBase::getResultProperties
	* ApiBase::getFinalResultProperties
	* ApiBase::addTokenProperties
	* ApiBase::getRequireOnlyOneParameterErrorMessages
	* ApiBase::getRequireMaxOneParameterErrorMessages
	* ApiBase::getRequireAtLeastOneParameterErrorMessages
	* ApiBase::getTitleOrPageIdErrorMessage
	* ApiBase::getPossibleErrors
	* ApiBase::getFinalPossibleErrors
	* ApiBase::parseErrors
	* ApiQuery::setGeneratorContinue
	* ApiQueryBase::checkRowCount
	* ApiQueryBase::titleToKey
	* ApiQueryBase::keyToTitle
	* ApiQueryBase::keyPartToTitle
	* ApiQueryInfo::getTokenFunctions
	* ApiQueryInfo::resetTokenCache
	* ApiQueryInfo::getEditToken
	* ApiQueryInfo::getDeleteToken
	* ApiQueryInfo::getProtectToken
	* ApiQueryInfo::getMoveToken
	* ApiQueryInfo::getBlockToken
	* ApiQueryInfo::getUnblockToken
	* ApiQueryInfo::getEmailToken
	* ApiQueryInfo::getImportToken
	* ApiQueryInfo::getWatchToken
	* ApiQueryInfo::getOptionsToken
	* ApiQueryRecentChanges::getTokenFunctions
	* ApiQueryRecentChanges::getPatrolToken
	* ApiQueryRevisions::getTokenFunctions
	* ApiQueryRevisions::getRollbackToken
	* ApiQueryUsers::getTokenFunctions
	* ApiQueryUsers::getUserrightsToken
	* The following classes have been deprecated and may be removed in a future
	release:
	* ApiFormatDbg
	* ApiFormatDump
	* ApiFormatTxt
	* ApiFormatWddx
	* ApiFormatYaml
	* ApiTokens
	* The following class constants have been deprecated and may be removed in a
	future release:
	* ApiBase::PROP_ROOT
	* ApiBase::PROP_LIST
	* ApiBase::PROP_TYPE
	* ApiBase::PROP_NULLABLE

	=== Languages updated in 1.24 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Bugzilla reports.

	=== Other changes in 1.24 ===
	* The deprecated jquery.delayedBind ResourceLoader module was removed.
	* The deprecated function mw.util.toggleToc was removed.
	* The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
	were removed as they were unused.
	* (bug 65477) User::pingLimiter() now has an additional profile point varying
	by action being used.
	* mediawiki.util.$content no longer supports old versions of the Vector,
	Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
	and/or "mw-body-primary" class name in their html.
	* Added pp_sortkey column to page_props table, so pages can be efficiently
	queried and sorted by property value (bug 58032).
	See $wgPagePropsHaveSortkey if you want to postpone the schema change.
	* BREAKING CHANGE: All four built-in MediaWiki skins (Vector, MonoBook, Modern
	and Cologne Blue) were moved out of MediaWiki core to their own respective
	repositories. They will be installed with the release tarball, but you must
	install them separately if installing MediaWiki from source code. A warning
	message displayed until you do it should guide you through the process. See
	also <https://www.mediawiki.org/wiki/Manual:Skin_configuration>.
	* BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
	the "headelement" template key are no longer supported. Setting
	$useHeadElement = false; is no longer supported and will not cause old keys
	like "headlinks", "skinnameclass", etc. to be defined.
	* BREAKING CHANGE: The files commonElements.css, commonContent.css and
	commonInterface.css (in skins/common/) have been removed. Skins may no longer
	rely on their presence and include them in their style modules. ResourceLoader
	modules introduced in MediaWiki 1.23 should be loaded instead:
	- skins/common/commonElements.css → 'mediawiki.skinning.elements' module
	- skins/common/commonContent.css → 'mediawiki.skinning.content' module
	- skins/common/commonInterface.css → 'mediawiki.skinning.interface' module
	* The deprecated 'SpecialVersionExtensionTypes' hook was removed.
	* (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
	* SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
	Special pages should subclass SpecialPage and implement the execute() method.
	* (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
	removed.
	* Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
	* The skin autodiscovery mechanism has been deprecated and will be removed in
	MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
	for migration guide for creators and users of custom skins that relied on it.
	* ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
	skin style files used by the module.

	* Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
	* Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
	* Removed info(), purge(), revert() and rollback() from the Article class; they
	have since become subclasses of the Action class. (deprecated since 1.19)
	* SearchEngineReplacePrefixesComplete hook was removed.
	* The "jquery.json" module has been deprecated. Use the "json" module instead.
	* Removed HTMLForm::addJS(). (deprecated since 1.18)
	* Removed LogEventsList::showHeader(). (deprecated since 1.19)
	* Removed ImageGalleryBase::useSkin(). (deprecated since 1.18)

	* Removed Language::getFallbackLanguageCode(). (deprecated since 1.19)
	* Removed WikiPage::isBigDeletion(). (deprecated since 1.19)
	* Removed MWInit class which contained functions related to a now discontinued
	PHP compiler called hphpc. (deprecated since 1.22)
	* ApiResult::enableSizeCheck() and disableSizeCheck() are now obsolete.
	* Removed ResourceLoaderGetStartupModules hook. (deprecated since 1.23)
	* Removed getFormFields(), onSubmit() and onSuccess() from FormlessAction, as
	these were meant specifically for FormAction instead.
	* Removed Action::execute().
	* Removed AjaxAddScript which has been obsolete since ResourceLoader and
	is unused by any modern extension.
	* Removed maintenance/nextJobDB.php; no longer in use.
	* Removed global function wfViewPrevNext(). (deprecated since 1.19)
	* Removed global function xmlsafe() from Export.php. (moved to OAIRepo
	extension)
	* Removed Title::userCanRead(). (deprecated since 1.19)
	* Removed maintenance script importTextFile.php. Use edit.php script instead.
	* A _from_namespace field has been added to the templatelinks, pagelinks,
	and filelinks tables. Run update.php to apply this change to the schema.
	* Removed File::sha1Base36(). (deprecated since 1.19)
	* Removed File::getPropsFromPath(). (deprecated since 1.19)
	* Removed functions blockedPage(), noCreatePermission(), readOnlyPage() and
	userNotLoggedInPage() from EditPage.php. (deprecated since 1.19)
	* Removed functions getContent(), getPreloadedText(), mergeChangesInto() and
	setPreloadedText() from EditPage.php. (deprecated since 1.21)
	* Removed global functions wfArrayLookup(), wfArrayMerge(),
	wfDebugDieBacktrace() and wfTime(). (deprecated since 1.22)
	* Browser support for Internet Explorer 6 and 7 lowered from Grade A to Grade C,
	meaning that JavaScript is no longer executed in these browser versions.
	* Browser support for Opera 11 lowered from Grade A to Grade C.
	* Removed IEFixes module which existed purely to provide support for MSIE
	versions below 7 (conditionally loaded only for those browsers).
	* Deprecated SpecialPageFactory::getList() in favor of
	SpecialPageFactory::getNames()
	* Action::checkCanExecute() no longer has a return value.
	* Removed cleanupForIRC(), loadFromCurRow(), newFromCurRow(), notifyRC2UDP()

	* Removed Xml::namespaceSelector(). (deprecated since 1.19)
	* Removed WikiPage::estimateRevisionCount(). (deprecated since 1.19)
	* MYSQL: Enum item added to "major MIME type" columns.
	Running update.php on MySQL < v5.1 may result in heavy processing.
	* RSS and Atom feeds generated by MediaWiki no longer include a fallback
	stylesheet. It was ignored by most browsers these days anyway.
	* SpecialSearchNoResults hook has been removed. SpecialSearchResults is now
	called unconditionally.
	* TablePager::getBody() is now 'final' and can't be overridden in subclasses.
	* TablePager::getBody() is deprecated, use getBodyOutput() or getFullOutput().
	* Added $outputPage parameter to the SkinTemplateGetLanguageLink hook.
	* log_page for move log entries store the original page ID, rather than that
	of the new redirect page. This is not retroactive.
	* LCStoreAccel was removed. $wgLocalisationCacheConf can no longer be set to
	use this store class.
	* Html::infoBox() no longer accepts paths relative to skins/common/images/.
	* Deprecated defunct Skin::getCommonStylePath().
	* Some extensions had their ResourceLoader modules depend on the "mediawiki"
	and "jquery" modules. In the past, this behavior was undefined, now it will
	throw an error.
	* Removed BagOStuff::replace(). (deprecated since 1.23)
	* In Linker.php, link(), linkText() and makeBrokenImageLinkObj() now display
	warnings if their first parameter is not a Title object. Also makeImageLink()
	now requires a Parser as its first parameter.
	* (bug 67368) LESS functions embed() and embeddable(), added in MediaWiki 1.23
	and broken by design, have been removed. Use appropriate LESS mixins instead.
	* Removed cssjanus.py from maintenance directory as it was unused.
	* Removed maintenance/purgeOldText.inc and the PurgeRedundantText() function
	it contained (superseded by Maintenance::purgeRedundantText() in 1.16).
	The purgeOldText.php maintenance script has been retained.
	* PHPUnit tests can be found by directory discovery, by adding the directory
	path from your UnitTestsList callback. Older versions of MediaWiki core will
	barf at this usage.

	* (T151735) SECURITY: SVG filter evasion using default attribute values in DTD
	declaration.
	* (T48143) SECURITY: Spam blacklist ineffective on encoded URLs inside file
	inclusion syntax's link parameter.
	* (T108138) SECURITY: Sysops can undelete pages, although the page is protected
	against it.

	This is a maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.14 ===

	== MediaWiki 1.23.12 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.11 ===
	* (T117899) SECURITY: $wgArticlePath can no longer be set to relative paths
	that do not begin with a slash. This enabled trivial XSS attacks.
	Configuration values such as "http://my.wiki.com/wiki/$1" are fine, as are
	"/wiki/$1". A value such as "$1" or "wiki/$1" is not and will now throw an
	error.

	* (T102562) Fix InstantCommons parameters to handle the new HTTPS-only
	policy of Wikimedia Commons.

	== MediaWiki 1.23.9 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.8 ===

	* (T85848, T71210) SECURITY: Don't parse XMP blocks that contain XML entities,

	* (bug T68650) Fix indexing of moved pages with PostgreSQL. Requires running
	update.php to fix.
	* (bug T70087) Fix Special:ActiveUsers page for installations using
	PostgreSQL.

	== MediaWiki 1.23.8 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.7 ===

	* (bug T76686) [SECURITY] thumb.php outputs wikitext message as raw HTML, which
	could lead to xss. Permission to edit MediaWiki namespace is required to
	exploit this.
	* (bug T77028) [SECURITY] Malicious site can bypass CORS restrictions in
	$wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as
	part of its name.
	* (bug T74222) The original patch for T74222 was reverted as unnecessary.

	== MediaWiki 1.23.7 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.6 ===

	* (bugs 66776, 71478) SECURITY: User PleaseStand reported a way to inject code
	into API clients that used format=php to process pages that underwent flash
	policy mangling. This was fixed along with improving how the mangling was done
	for format=json, and allowing sites to disable the mangling using
	$wgMangleFlashPolicy.
	* (bug 70901) SECURITY: User Jackmcbarn reported that the ability to update
	the content model for a page could allow an unprivileged attacker to edit
	another user's common.js under certain circumstances. The user right
	"editcontentmodel" was added, and is needed to change a revision's content
	model.
	* (bug 71111) SECURITY: User PleaseStand reported that on wikis that allow raw
	HTML, it is not safe to preview wikitext coming from an untrusted source such
	as a cross-site request. Thus add an edit token to the form, and when raw HTML
	is allowed, ensure the token is provided before showing the preview. This
	check is not performed on wikis that both allow raw HTML and anonymous
	editing, since there are easier ways to exploit that scenario.
	* (bug 72222) SECURITY: Do not show log action when the entry is revdeleted with
	DELETED_ACTION. NOTICE: this may be reverted in a future release pending a
	public RFC about the desired functionality. This issue was reported by user
	Bawolff.
	* (bug 71621) Make allowing site-wide styles on restricted special pages a
	config option.
	* (bug 42723) Added updated version history from 1.19.2 to 1.22.13
	* $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
	might be a flash policy directive configurable.

	== MediaWiki 1.23.6 ==

	This is a maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.5 ===
	* (Bug 72274) Job queue not running (HTTP 411) due to missing
	Content-Length: header
	* (Bug 67440) Allow classes to be registered properly from installer

	== MediaWiki 1.23.5 ==

	This is a security release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.4 ===
	* (bug 70672) SECURITY: OutputPage: Remove separation of css and js module
	allowance.

	== MediaWiki 1.23.4 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.3 ===

	* (bug 69008) SECURITY: Enhance CSS filtering in SVG files. Filter <style>
	elements; normalize style elements and attributes before filtering; add
	checks for attributes that contain css; add unit tests for html5sec and
	reported bugs.
	* (bug 65998) Make MySQLi work with non-standard socket.
	* (bug 66986) GlobalVarConfig shouldn't throw exceptions for null-valued config
	settings.

	== MediaWiki 1.23.3 ==

	This is a maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.2 ===

	* (bug 68501) Correctly handle incorrect namespace in cleanupTitles.php.
	* (bug 64970) Fix support for blobs on DatabaseOracle::update.
	* (bug 66574) Display MediaWiki:Loginprompt on the login page.
	* (bug 67870) wfShellExec() cuts off stdout at multiples of 8192 bytes.
	* (bug 60629) Handle invalid language code gracefully in
	Language::fetchLanguageNames.
	* (bug 62017) Restore the number of rows shown on Special:Watchlist.
	* Check for boolean false result from database query in SqlBagOStuff.

	== MediaWiki 1.23.2 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.1 ===

	* (bug 68187) SECURITY: Prepend jsonp callback with comment.
	* (bug 66608) SECURITY: Fix for XSS issue in bug 66608: Generate the URL used
	for loading a new page in Javascript,instead of relying on the URL in the link
	that has been clicked.
	* (bug 65778) SECURITY: Copy prevent-clickjacking between OutputPage and
	ParserOutput.
	* (bug 68313) Preferences: Turn stubthreshold back into a combo box.
	* (bug 65214) Fix initSiteStats.php maintenance script.
	* (bug 67594) Special:ActiveUsers: Fix to work with PostgreSQL.

	== MediaWiki 1.23.1 ==

	This is a security and maintenance release of the MediaWiki 1.23 branch.

	=== Changes since 1.23.0 ===

	* (bug 65839) SECURITY: Prevent external resources in SVG files.
	* (bug 67025) Special:Watchlist: Don't try to render empty row.
	* (bug 66922) Don't allow some E_NOTICE messages to end up in the
	LocalSettings.php.
	* (bug 66467) FileBackend: Avoid using popen() when "parallelize" is disabled.
	* (bug 66428) MimeMagic: Don't seek before BOF. This has weird side effects
	like only extracting the tail of the file partially or not at all.
	* (bug 66182) Removed -x flag on some php files.

	== MediaWiki 1.23.0 ==

	=== Configuration changes in 1.23 ===
	* (bug 13250) Restored method for clearing a watchlist in web UI
	so that users with large watchlists don't have to perform
	contortions to clear them.
	* When $wgJobRunRate is higher than zero, jobs are now executed via an
	asynchronous HTTP request to a MediaWiki entry point. This may require
	increasing the number of server worker threads. $wgRunJobsAsync has been
	added to disable this feature if needed, falling back to executing the job
	on the same process but making the execution synchronously.
	* $wgDebugLogGroups values may be set to an associative array with a
	'destination' key specifying the log destination. The array may also contain
	a 'sample' key with a positive integer value N indicating that the log group
	should be sampled by dispatching one in every N messages on average. The
	sampling is random.
	* In addition to the current exception log format, MediaWiki now serializes
	exception metadata to JSON and logs it to the 'exception-json' log group.
	This makes MediaWiki easier to integrate with log aggregation and analysis
	tools.
	* $wgSquidServersNoPurge now supports the use of Classless Inter-Domain
	Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6
	addresses that should be trusted to provide X-Forwarded-For headers.
	* Preferences 'watchcreations', 'watchdefault', 'enotifwatchlistpages' ("Add
	pages I create and files I upload to my watchlist", "Add pages and files I
	edit to my watchlist", "Email me when a page or file on my watchlist is
	changed") are now enabled by default. In addition new user accounts' personal
	and talk pages are now watched by them by default.
	* $wgLBFactoryConf: Class names have had underscores removed. The configuration
	should be updated if LBFactory_Simple or LBFactory_Multi is configured.
	* $wgPasswordSenderName has been removed and is no longer functional. To set a
	custom mailer name, the system message 'emailsender' should be modified
	(default: "{{SITENAME}}").
	* (bug 63269) Email notifications were not correctly handling the
	[[MediaWiki:Helppage]] message being set to a full URL (the default).
	If you customized [[MediaWiki:Enotif body]] (the text of email notifications),
	you'll need to edit it locally to include the URL via the new variable
	$HELPPAGE instead of the parser functions fullurl and canonicalurl; otherwise
	you don't have to do anything.
	* $wgDBAhandler was removed as the only class using it was also removed
	* The 'max threads' setting was removed from $wgDBservers.
	* Support for AdminSettings.php has been completely removed. All configuration
	belongs in LocalSettings.php.
	* $wgSkipSkin, which has been replaceable by $wgSkipSkins since 2005 (r9249), is
	now formally deprecated.
	* Removed deprecated $wgDisabledActions as it is hardly used anywhere.
	* $wgRateLimitLog has been deprecated and replaced by
	$wgDebugLogGroup['ratelimit'].
	* $wgLocalInterwikis is an array containing multiple local interwiki prefixes
	(interwiki prefixes that point back to the current wiki). This effectively
	allows more than one value of $wgLocalInterwiki to be specified and
	understood by the parser. The value of $wgLocalInterwiki is automatically
	prepended to the start of this array.
	* $wgQueryPages has been removed. Query Pages should be added to by using the
	wgQueryPages hook.
	* $wgHttpOnlyBlacklist has been removed.
	* $wgLicenseTerms has been removed as it was unused.
	* $wgProfileOnly is now deprecated; set the log file in
	$wgDebugLogGroups['profileoutput'] to replace it.
	* $wgMaxBacklinksInvalidate was removed; use $wgJobBackoffThrottling instead
	* Deprecated ResourceLoaderGetStartupModules hook.

	=== New features in 1.23 ===
	* ResourceLoader can utilize the Web Storage API to cache modules client-side.
	Compared to the browser cache, caching in Web Storage allows ResourceLoader
	to be more granular about evicting stale modules from the cache while
	retaining the ability to retrieve multiple modules in a single HTTP request.
	This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
	true. This feature is currently considered experimental and should only be
	enabled with care.
	* (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
	and {{REVISIONTIMESTAMP:}} (with friends).
	* Add "wgRelevantUserName" to mw.config containing the current
	Skin::getRelevantUser value.
	* (bug 56033) Add content model to the page information.
	* Added Article::MissingArticleConditions hook to give extensions a chance to
	hide their (unrelated) log entries.
	* Added LonelyPagesQuery hook to let extensions modify the query used to
	generate Special:LonelyPages.
	* Added $wgOpenSearchDefaultLimit defining the default number of entries to show
	on action=opensearch API call.
	* For namespaces with $wgNamespaceProtection (including the MediaWiki
	namespace), the "protect" tab will be shown only if there are restriction
	levels available that would restrict editing beyond what
	$wgNamespaceProtection already applies. The protection form will offer only
	those protection levels.
	* Added $wgAPIFormatModules, allowing extensions to add additional output
	formatting modules for the API.
	* (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add
	custom CSS or JavaScript enabled only for registered users.
	* (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist
	now include a legend describing the symbols used in lists of changes.
	* Improved the accessibility of the tabs in Special:Preferences.
	* Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook:
	it's called after everything is set up but before any major processing
	happens.
	* The jquery.client module now performs a component-wise version comparison in
	its #test method when strings are used in the browser map: version '1.10' is
	now correctly considered larger than '1.2'. Using numbers in the version map
	is not affected.
	* All API modules now support an assert parameter, which can either be
	'user' or 'bot'. The API will throw an error if the user is not logged
	in (user) or does not have the 'bot' userright (bot). Based off of the
	AssertEdit extension by Steve Sanbeg.
	* [[Special:Diff]] was added, allowing users to create internal links to
	revision comparison pages using syntax such as [[Special:Diff/12345]],
	[[Special:Diff/12345/prev]] or [[Special:Diff/12345/98765]].
	* New user accounts' personal and talk pages are now watched by them by default.
	* Added SkinTemplateGetLanguageLink hook to allow changing the html of language
	links.
	* Added MessageCache::get hook as a new way to customize messages across
	multiple sites.
	* Added jquery.throttle-debounce ResourceLoader module to limit the number of
	callbacks for frequently occurring events.
	* Special:ProtectedPages shows now a table. The timestamp, the reason and
	the protecting user are also shown.
	* Added experimental support for using Microsoft SQL Server as the database
	backend.
	** Added new Microsoft SQL Server-specific configuration variable
	$wgDBWindowsAuthentication, which makes the web server authenticate against
	the database server using Integrated Windows Authentication instead of
	$wgDBuser/$wgDBpassword.
	* HTMLForm 'select', 'selectandother', 'selectorother', 'multiselect', and
	'radio' fields can now use message keys as labels via the 'options-messages'
	parameter, which overrides the 'options' parameter.
	* Admins can expire users passwords manually, or on a schedule using the
	$wgPasswordExpirationDays configuration setting.
	* Add new hook SendWatchlistEmailNotification, this will be used to determine
	whether to send a watchlist email notification.
	* (bug 42026) Special:Contributions now includes an option to filter page
	creations, similar to the topOnly option.
	* Add mediawiki.ui.button styling to all pages so wiki content can use styled
	buttons.
	* Special:UserLogin/signup now does AJAX checks for invalid and taken usernames,
	displaying the error live.
	* Added BaseTemplateAfterPortlet hook to allow injecting html after portlets in
	skins.
	* Support has been added for a JSON based localisation file format. The
	installer has been updated to use it.
	* Changes to content typography (colors, line-height etc.). See
	https://www.mediawiki.org/wiki/Typography_refresh for further information.
	* The Vector skin's visual treatment of external links has been simplified to a
	single icon (from nine). This should not affect local rules unless they were
	re-using these icons, which have now been deleted.
	* ResourceLoader: mw.loader.using() now implements a Promise interface.
	* Add new hook ChangesListInitRows accessed via
	ChangesList::initChangesListRows.
	If called by the ChangesList consumer this gives extensions a chance to batch
	process the result set prior to rendering.
	* A PoolCounterRedis class was added which can be make use of in
	$wgPoolCounterConf. This requires at least one Redis 2.6+ server.
	* $wgProfileToDatabase was removed. Set $wgProfiler to ProfilerSimpleDB
	in StartProfiler.php instead of using this.
	* (bug 63444) Made it possible to change the indent string (default: 4 spaces)
	used by FormatJson::encode().

	=== Bug fixes in 1.23 ===
	* (bug 41759) The "updated since last visit" markers (on history pages, recent
	changes and watchlist) and the talk page message indicator are now correctly
	updated when the user is viewing old revisions of pages, instead of always
	acting as if the latest revision was being viewed.
	* (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
	when the email address is already confirmed. Also, consistently use
	"confirmed", rather than "authenticated", when messaging whether or not the
	user has confirmed an email address.
	* (bug 19415) action=render no longer shows section edit links. This affects
	behavior of several other features where (bogus) section edit links will
	disappear, such as file description pages loaded via $wgUseInstantCommons or
	pages transcluded cross-wiki via $wgEnableScaryTranscluding.
	* (bug 56912) Show correct link color on cached result of Special:DeadendPages.
	* Classes TitleListDependency and TitleDependency have been removed, as they
	have been found unused in core and extensions for a long time.
	* (bug 57098) SpecialPasswordReset now obeys returnto parameter
	* (bug 37812) ResourceLoader will notice when a module's definition changes and
	recompile it accordingly.
	* (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds.
	* (bug 58640) Fixed a compatibility issue with PCRE 8.34 that caused pages
	to appear blank or with missing text.
	* (bug 56931) Updated the plural rules to CLDR 24. They are in new format
	which is detailed in UTS 35 Rev 33. The PHP parser and evaluator as well as
	the JavaScript evaluator were updated to support the new format. Plural rules
	for some languages have changed, most notably Russian. Affected software
	messages have been updated and marked for review at translatewiki.net.
	* (bug 23542) imagelinks now stores both the redirect and target (as
	templatelinks does).
	* (bug 58167) The web installer no longer throws an exception when PHP is
	compiled without support for MySQL yet with support for another DBMS.
	* (bug 56199) Raw option of parser functions must now match complete word,
	to take effect.
	* (bug 60543) Special:PrefixIndex forgot stripprefix=1 for "Next page" link
	* (bug 29762) Undoing an already-undone edit will now display an appropriate
	message instead of leading the user to make a null edit.
	* (bug 52659) mediawiki.notification: Notification area remained visible when
	empty and thus was stealing pointer events from links on the page.
	* (bug 26811) When a DBUnexpectedError occurs, DB server hostnames are now
	hidden unless $wgShowExceptionDetails is true, and $wgShowDBErrorBacktrace
	no longer applies in such cases.
	* (bug 60960) Avoid doing file_exist() checks on data: URIs, as they cause
	warnings to be printed on Windows due to large path length.
	* (bug 48084) Fixed a bug in the installer that could cause $wgLogo to hold
	the wrong path to the placeholder logo (skins/common/images/wiki.png).
	* (bug 64289) jquery.textSelection: Don't throw errors on empty collections.

	=== Web API changes in 1.23 ===
	* (bug 54884) action=parse&prop=categories now indicates hidden and missing
	categories.
	* action=query&meta=filerepoinfo now returns additional information for each
	repo.
	* action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
	MediaWiki 1.24.
	* action=parse now has disabletoc flag to disable table of contents in output.
	* (bug 25702) list=allcategories, list=allimages, list=alllinks, list=allpages,
	list=deletedrevs and list=filearchive did not handle case-sensitivity
	properly for all parameters.
	* ApiQueryBase::titlePartToKey allows an extra parameter that indicates the
	namespace in order to properly capitalize the title part.
	* (bug 57874) action=feedcontributions no longer has one item more than limit.
	* All API modules now support an assert parameter. See the new features section
	for more details.
	* Added prop=contributors to fetch the list of contributors to the page.
	* The following API modules will now return entries where fields have been
	revision-deleted: list=deletedrevs, list=filearchive, list=recentchanges,
	list=watchlist. "hidden" indicators will be included, in the same style as is
	already done for prop=revisions.
	* The following API modules will now return the content of revision-deleted
	fields, in addition to the "hidden" indicators, if the querying user has the
	necessary rights: list=logevents, list=usercontribs, prop=imageinfo,
	prop=revisions.
	* The above modules, where applicable, will now return entries filtered by
	revision-deleted fields if the querying user has the necessary rights. For
	example, prop=revisions with rvuser or rvexcludeuser will no longer skip
	revisions where the user was revision-deleted if the current user has the
	deletedhistory right.
	* The 'hideuser' right, used when blocking, is no longer necessary or
	sufficient for seeing contributions with revision-deleted in
	list=usercontribs.
	* list=watchlist now uses the querying user's rights rather than the wlowner's
	rights when checking whether wlprop=patrol is allowed.
	* (bug 32151) ApiWatch now has pageset capabilities (titles/pageids/generators).
	Title parameter is now deprecated.
	* (bug 23005) Added action=revisiondelete.
	* Added siprop=restrictions to API action=query&meta=siteinfo for querying
	possible page restriction (protection) levels and types.
	* Added prop 'limitreportdata' and 'limitreporthtml' to action=parse.
	* (bug 58627) Provide language names on action=parse&prop=langlinks.
	* Deprecated llurl= in favour of llprop=url for action=query&prop=langlinks.
	* Added llprop=langname and llprop=autonym for action=query&prop=langlinks.
	* prop=redirects is added, to return redirects to the pages in the query.
	* list=allredirects is added, to list all redirects pointing to a namespace.
	* (bug 42026) Added ucshow={new,!new,top,!top} to list=usercontribs.
	Also added newonly to action=feedcontributions.
	* (bug 42026) Deprecated uctoponly in favor of ucshow=top.
	* list=search no longer has a "srredirects" parameter. Redirects are now
	included in all searches.
	* Added list=prefixsearch that works like action=opensearch but can be used as
	a generator.
	* (bug 24782) Various modules will now use unique continuation parameters.
	* (bug 63249) Cache RecentChanges Atom feed in varnish for 15 seconds.

	=== Languages updated in 1.23 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Bugzilla reports.

	* Support was added for Algerian Spoken Arabic (arq).
	* Support was added for Riograndenser Hunsrückisch (hrx).
	* Support was added for Northern Luri (lrc).

	=== Other changes in 1.23 ===
	* The rc_type field in the recentchanges table has been superseded by a new
	rc_source field. The rc_source field is a string representation of the
	change type where rc_type was a numeric constant. This field is not yet
	queried but will be in a future release.
	** Utilize update.php to create and populate this new field. On larger wikis
	which do not wish to update recentchanges table in one large update please
	review the SQL and comments in maintenance/archives/patch-rc_source.sql.
	** The rc_type field of recentchanges will be deprecated in a future release.
	* The global variable $wgArticle has been removed after a lengthy deprecation.
	* The global functions addButton and insertTags (for mw.toolbar.addButton and
	mw.toolbar.insertTags) now emits mw.log.warn when accessed.
	* The ExpandTemplates extension has been moved into MediaWiki core.
	* (bug 52812) Removed "Disable search suggestions" from Preference.
	* (bug 52809) Removed "Disable browser page caching" from Preference.
	* Three new modules intended for use by custom skins were added:
	'mediawiki.skinning.elements', 'mediawiki.skinning.content', and
	'mediawiki.skinning.interface', representing three levels of standard
	MediaWiki styling. Previously skin creators wishing to use them had to refer
	to the file names of appropriate files directly, which is now discouraged.
	* The modules 'skins.vector' and 'skins.monobook' have been renamed to
	'skins.vector.styles' and 'skins.monobook.styles', respectively,
	and their definition was changed not to include the common*.css files;
	the two skins now load the 'mediawiki.skinning.interface' module instead.
	* A page_links_updated field has been added to the page table.
	* SpecialPage::getTitle has been deprecated in favor of
	SpecialPage::getPageTitle.
	* BREAKING CHANGE: Two potentially backwards-incompatible changes have been made
	to the 'SpecialWatchlistQuery' hook's last parameter (array $values) to make
	the hook more consistent with the 'SpecialRecentChangesQuery' one:
	** Several array keys have been renamed: hideMinor → hideminor,
	hideBots → hidebots, hideAnons → hideanons, hideLiu → hideliu,
	hidePatrolled → hidepatrolled, hideOwn → hidemyself.
	** The parameter value is now a FormOptions object, not a plain array (array
	access operators should continue to work, as it implements the ArrayAccess
	interface).
	* Option to mark hooks as deprecated has been added.
	* (bug 52811) Preference "Enable section editing via [edit] links" was removed.
	* (bug 52813) Preference "Show table of contents (for pages with more than
	3 headings)" was removed.
	* (bug 52810) Preference "Justify paragraphs" was removed.
	* OutputPage::showErrorPage raises a notice if arguments are incoherent.
	* Thumbnails that keep failing to render in thumb.php will be rate-limited
	against further render attempts for 1 hour. $wgAttemptFailureEpoch can be
	altered to reset all rate-limited thumbnails at once.
	* (bug 56572) Builds of the OOjs and OOjs UI libraries are now available.
	* mw.loader.go and mw.loader.version have been removed.
	* (bug 52815) Preference "Enable simplified search bar (Vector skin only)"
	was removed.
	* A user_password_expires column has been added to the user table. The User
	object expects this column to exist. Use update.php to create this new field.
	* The jquery.delayedBind ResourceLoader module was deprecated in favor of the
	jquery.throttle-debounce module. It will be removed in MediaWiki 1.24.
	* mw.user.bucket has been deprecated.
	* On Special:PrefixIndex, a table#mw-prefixindex-list-table was changed to
	table.mw-prefixindex-list-table to avoid duplicate ids when the special page
	is transcluded.
	* (bug 62198) window.$j has been deprecated.
	* Preference "Disable link title conversion" was removed.
	* SpecialRecentChanges no longer includes any functionality for generating feeds
	- it has been factored out to ApiFeedRecentChanges. Old URLs redirect to new
	ones.
	* RecentChange::mExtra['lang'] is no longer set and should no longer be used.
	Extensions should read from other configuration variables, including
	$wgLocalInterwikis, to identify the current wiki.
	* Sections in the parser test framework have been renamed and the old
	section names are deprecated. Please use "!!wikitext" and "!!html"
	(or "!!html/php") instead of "!!input" and "!!result". This allows
	us to extend parser tests to accommodate additional input/output
	pairs, such as "!!html/parsoid" (for the output of the Parsoid
	parser, where it differs from the PHP parser).
	* Special:Search no longer has an "include redirects" option on the advanced
	tab. Redirects are now included in all searches.
	* mediawiki.api.category's getCategories() 'async' parameter was deprecated.
	* The locations of resources have been split between upstream libraries, now in
	resources/lib/, local libaries in resources/src/, and local forks of upstream
	libraries, also in resources/src/.
	* BREAKING CHANGE: The automatically-generated function closure with which
	ResourceLoader wraps all modules' JavaScript code now binds the identifier
	names 'jQuery' and '$' to the jQuery object of the version of jQuery that is
	bundled with MediaWiki. If you bind these names to other objects in global
	scope (like Zepto.js or document.querySelectorAll, for example) you will need
	to use different names to or re-bind them at the top of each
	ResourceLoader-loaded module.
	* (bug 52342) Preference "Remember my login" was removed.
	* The skin autodiscovery mechanism has been deprecated and will be removed in
	MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
	for migration guide for creators and users of custom skins that relied on it.

	= MediaWiki 1.22 =

	== MediaWiki 1.22.15 ==

	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.14 ===

	* (bug T76686) [SECURITY] thumb.php outputs wikitext message as raw HTML, which
	could lead to xss. Permission to edit MediaWiki namespace is required to
	exploit this.
	* (bug T77028) [SECURITY] Malicious site can bypass CORS restrictions in
	$wgCrossSiteAJAXdomains in API calls if it only included an allowed domain as
	part of its name.
	* (bug T74222) The original patch for T74222 was reverted as unnecessary.

	== MediaWiki 1.22.14 ==

	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.13 ===

	* (bugs 66776, 71478) SECURITY: User PleaseStand reported a way to inject code
	into API clients that used format=php to process pages that underwent flash
	policy mangling. This was fixed along with improving how the mangling was done
	for format=json, and allowing sites to disable the mangling using
	$wgMangleFlashPolicy.
	* (bug 70901) SECURITY: User Jackmcbarn reported that the ability to update
	the content model for a page could allow an unprivileged attacker to edit
	another user's common.js under certain circumstances. The user right
	"editcontentmodel" was added, and is needed to change a revision's content
	model.
	* (bug 72222) SECURITY: Do not show log action when the entry is revdeleted with
	DELETED_ACTION. NOTICE: this may be reverted in a future release pending a
	public RFC about the desired functionality. This issue was reported by user
	Bawolff.
	* (bug 71621) Make allowing site-wide styles on restricted special pages a
	config option.
	* $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
	might be a flash policy directive configurable.

	== MediaWiki 1.22.13 ==
	This is a maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.12 ===
	* (bug 67440) Allow classes to be registered properly from installer

	== MediaWiki 1.22.12 ==
	This is a security release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.11 ===
	* (bug 70672) SECURITY: OutputPage: Remove separation of css and js module
	allowance.

	== MediaWiki 1.22.11 ==
	This is a security release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.10 ===
	* (bug 69008) SECURITY: Enhance CSS filtering in SVG files. Filter <style>
	elements; normalize style elements and attributes before filtering; add checks
	for attributes that contain css; add unit tests for html5sec and reported
	bugs.

	== MediaWiki 1.22.10 ==
	This is a maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.9 ===
	* (bug 64970) Fix support for blobs on DatabaseOracle::update
	* (bug 60719) In MediaWiki 1.22, the job queue execution on each page request
	was changed (Gerrit change 59797) so, instead of executing the job inside the
	same PHP process that's rendering the page, a new PHP cli command is spawned
	to execute runJobs.php in the background. It will only work if $wgPhpCli is
	set to an actual path or safe mode is off, otherwise, the old method will be
	used. See
	https://www.mediawiki.org/wiki/Manual:Job_queue#Changes_in_MediaWiki_1.22
	for more information. This change was in earlier releases of 1.22 but was not
	noted here until now.

	== MediaWiki 1.22.9 ==
	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.8 ===
	* (bug 68187) SECURITY: Prepend jsonp callback with comment.
	* (bug 66608) SECURITY: Fix for XSS issue in bug 66608: Generate the URL used
	for loading a new page in Javascript,instead of relying on the URL in the
	link that has been clicked.
	* (bug 65778) SECURITY: Copy prevent-clickjacking between OutputPage and
	ParserOutput.
	* (bug 59147) The img_metadata field was not being decoded from bytea into text.

	== MediaWiki 1.22.8 ==
	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.7 ===
	* (bug 65839) SECURITY: Prevent external resources in SVG files.
	* (bug 66428) MimeMagic: Don't seek before BOF. This has weird side effects like
	only extracting the tail of the file partially or not at all.

	== MediaWiki 1.22.7 ==
	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.6 ===
	* (bug 65501) SECURITY: Don't parse usernames as wikitext on
	Special:PasswordReset.
	* (bug 36356) Add space between two feed links.
	* (bug 63269) Email notifications were not correctly handling the
	MediaWiki:Helppage message being set to a full URL. This is a regression from
	the 1.22.5 point release, which made the default value for it a URL. If you
	customized MediaWiki:Enotif body (the text of email notifications), you'll
	need to edit it locally to include the URL via the new variable $HELPPAGE
	instead of the parser functions fullurl and canonicalurl; otherwise you don't
	have to do anything.
	* Add missing uploadstash.us_props for PostgreSQL.
	* (bug 56047) Fixed stream wrapper in PhpHttpRequest.

	== MediaWiki 1.22.6 ==
	This is a security release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.5 ===
	* (bug 63251) SECURITY: Escape sortKey in pageInfo.

	== MediaWiki 1.22.5 ==
	This is a security and maintenance release of the MediaWiki 1.22 branch.

	=== Changes since 1.22.4 ===
	* (bug 62497) SECURITY: Add CSRF token on Special:ChangePassword.
	* (bug 62467) Set a title for the context during import on the cli.
	* Fix custom local MediaWiki:Helppage values.
	* mediawiki.js: Fix documentation breakage.
	* (bug 58153) Make MySQLi work with non standard port.
	* (bug 53887) Reintroduced a link to help pages in the default sidebar, that any
	sysop can customize by editing MediaWiki:Sidebar locally. The link now points
	to a mediawiki.org page which is guaranteed to exist. Nothing needs to be done
	on your end, but remember to adjust MediaWiki:Sidebar for the needs of your
	wikis. Everyone can help with the shared documentation by translating:
	https://www.mediawiki.org/wiki/Special:Translate/agg-Help_pages .
	* (bug 53888) Corrected a regression in 1.22 which introduced red links on the
	login page. If you previously installed 1.22.x and have created a local page

	== MediaWiki 1.22.0 ==

	=== Configuration changes in 1.22 ===
	* $wgRedirectScript was removed. It was unused.
	* Removed $wgLocalMessageCacheSerialized, it is now always true.
	* $wgVectorUseIconWatch is now enabled by default.
	* $wgCascadingRestrictionLevels was added.
	* ftps, ssh, sftp, xmpp, sip, sips, tel, sms, bitcoin, magnet, urn, and geo
	have been whitelisted inside of $wgUrlProtocols.
	* $wgDocType and $wgDTD have been removed and are no longer used for the
	DOCTYPE.
	* $wgHtml5 is no longer used by core. Setting it to false will no longer disable
	HTML5. It is still set to true for extension compatibility but doing so in
	extensions is deprecated.
	* $wgXhtmlDefaultNamespace is no longer used by core. Setting it will no longer
	change the xmlns used by MediaWiki. Reliance on this variable by extensions
	is deprecated.
	* $wgHandheldStyle was removed.
	* $wgHandheldForIPhone was removed.
	* $wgJsMimeType is no longer used by core. Most usage has been removed since
	HTML output is now exclusively HTML5.
	* $wgDBOracleDRCP added. True enables persistent connection with DRCP on Oracle.
	* $wgLogAutopatrol added to allow disabling logging of autopatrol edits in the
	logging table.
	Default for $wgLogAutopatrol is true.
	* The 'edit' right no longer allows for editing a user's own CSS and JS.
	* New rights 'editmyusercss', 'editmyuserjs', 'viewmywatchlist',
	'editmywatchlist', 'viewmyprivateinfo', 'editmyprivateinfo', and
	'editmyoptions' restrict actions that were formerly allowed by default. They
	have been added to the default for $wgGroupPermissions['*'].
	* The 'editprotected' right no longer allows bypassing of all page protection
	restrictions. Any group using it for this purpose will now need to have all
	the individual rights listed in $wgRestrictionTypes for the same effect.
	* The 'protect' and 'autoconfirmed' rights are no longer used for the default
	page protection levels. The rights 'editprotected' and 'editsemiprotected'
	are now used for this purpose instead.
	* (bug 40866) wgOldChangeTagsIndex removed.
	* $wgNoFollowDomainExceptions now only matches entire domains. For example,
	an entry for 'bar.com' will still match 'foo.bar.com' but not 'foobar.com'.
	* $wgCopyUploadTimeout and $wgCopyUploadAsyncTimeout added to change the timeout
	times for fetching the file during upload by url.
	* New key added to $wgGalleryOptions - $wgGalleryOptions['mode'] to set
	default gallery mode.
	* New hook 'GalleryGetModes' to allow extensions to make new gallery modes.
	* The checkbox for staying in HTTPS displayed on the login form when
	$wgSecureLogin is enabled has been removed. Instead, whether the user stays in
	HTTPS will be determined
	based on the user's preferences, and whether they came from HTTPS or not.
	* $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort,
	and $wgRC2UDPPrefix configuration options have been deprecated in favor of a
	$wgRCFeeds configuration array. $wgRCFeeds makes both the format and
	destination of recent change notifications customizable, and allows for
	multiple destinations to be specified.
	* (bug 53862) portal-url, currentevents-url and helppage have been removed from
	the default Sidebar.
	* The 'vector-simplesearch' preference is now enabled by default. Previously
	it was only enabled if the Vector extension was installed.
	* The precise format of metric datagrams produced by the UDP profiler and stats
	counter may now be specified as $wgUDPProfilerFormatString and
	$wgStatsFormatString, respectively.
	* (bug 54597) $wgBlockOpenProxies, $wgProxyPorts, $wgProxyScriptPath, and
	$wgProxyMemcExpiry have been removed, along with the open proxy scanner
	script they were added for.
	* Default value of $wgMaxShellMemory has been tripled (it's now 300 MB).

	=== New features in 1.22 ===
	* You can now install extensions using Composer.
	See https://www.mediawiki.org/wiki/Composer
	* (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and
	attributes.
	* (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
	the "eIOPTZ" formatting characters.
	* EditWarning: A warning is shown when an editor leaves the edit form without
	saving (enabled by default, users can opt-out via the 'useeditwarning'
	preference). This feature was moved from the Vector extension, and is now part
	of core for all skins. Take care when upgrading that you don't use an older
	version of the Vector extension as this feature may conflict.
	* New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
	compact vertical form layout.
	* HTMLForm supports a new display format 'vform' which applies this compact
	vertical
	layout and button styling. Special:PasswordReset uses this format.
	* New versions of login (Special:UserLogin) and create account
	(Special:UserLogin/signup) forms using the "vform" compact vertical form
	layout. These forms use new messages that assume a "Help logging in" link, see
	https://www.mediawiki.org/wiki/Manual:Page_customizations;
	https://www.mediawiki.org/wiki/Account_creation_user_experience/Strings lists
	the message key changes.
	* (bug 23343) Implemented ability to apply IP blocks to the contents of
	X-Forwarded-For headers by adding a new configuration variable
	$wgApplyIpBlocksToXff (disabled by default).
	* The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
	added.
	* (bug 25592) LogEventsList::showLogExtract() will now ignore various
	Pager-related WebRequest parameters by default, as this is overwhelmingly
	likely to be what was intended by users of the method. If any caller wishes
	to use these parameters, the new param 'useRequestParams' may be set to true.
	* mw.util.addPortletLink: Tooltip is no longer required to be plain (without
	an accesskey in it already). As such it now rountrips. Creating a link with a
	message as tooltip, grabbing the title attribute and using it to create
	another portlet will work as expected.
	* (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
	page without namespace.
	* BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
	change their class name from .editsection to .mw-editsection and place them at
	the end of the heading element instead of the beginning. Client-side code and
	screen-scrapers will have to be adjusted to handle both cases (old HTML will
	still be visible on cached page renders until they are purged); extensions
	using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
	well.
	* (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
	language links associated with a page before display.
	* Chosen (http://harvesthq.github.io/chosen/) was added as module
	'jquery.chosen'
	* HTMLForm will turn multiselect checkboxes into a Chosen interface when setting
	cssclass 'mw-chosen'
	* rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
	of the specified languages instead of all of them.
	* New GetNewMessagesAlert hook allowing extensions to disable or modify the new
	messages alert
	* New wgUserNewMsgRevisionId JS global for logged in users. This will be null
	if the user has no new talk page messages. Otherwise it will be set to the
	revision ID of the oldest new talk page message. This will allow gadgets and
	extensions to create their own new message alerts on the client side.
	* mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
	* mediawiki.log: Implemented log.deprecate. This method defines a property and
	uses ES5 getter/setter to emit a warning when they are used.
	* $wgCascadingRestrictionLevels was added, allowing one to specify restriction
	levels which can be cascading (previously 'sysop' was hard-coded as the only
	one).
	* XHTML5 support has been improved. If you set
	$wgMimeType = 'application/xhtml+xml' MediaWiki will try outputting markup
	according to XHTML5 rules.
	* Altered hook 'ProtectionForm::save', adding the reason page protection is
	changed as third parameter.
	* New hook 'TitleSquidURLs' for manipulating the list of URLs to be purged from
	HTTP caches when a page is changed.
	* Changed the patrolling system to always show the link for patrolling in case
	the current revision is patrollable. This also removed the usage of the rcid
	URI parameters.
	* Oracle DB backend now supports Database Resident Connection Pooling (DRCP).
	Can be enabled by setting $wgDBOracleDRCP=true.
	Requires Oracle DB 11gR1 or above, enabled DRCP inside the DB itself and a
	propper connect string.
	More about DRCP can be found at:
	https://oracle-base.com/articles/11g/database-resident-connection-pool-11gr1
	* Add a new parameter $patrolFooterShown to hook ArticleViewFooter so the hook
	handlers can take further action based on the status of the patrol footer
	* A new hook TitleQuickPermissions was added to allow overriding of quick
	permissions in the Title class.
	* LinkCache singleton can now be altered or cleared, letting one to specify
	another instance that does not rely on a database backend.
	* MediaWiki's PHPUnit tests can now use PHPUnit installed using composer --dev.
	* (bug 43689) The lists of templates used on the page and hidden categories it
	is a member of, shown below the edit form, are now collapsible (and collapsed
	by default).
	* Parser profiling data, formerly only available in the "NewPP limit report"
	HTML comment, is now also displayed at the bottom of page previews.
	* Added ParserLimitReportPrepare and ParserLimitReportFormat hooks, deprecated
	ParserLimitReport hook.
	* New user rights have been added to increase granularity in rights management
	for extensions such as OAuth:
	** editmyusercss controls whether a user may edit their own CSS subpages.
	** editmyuserjs controls whether a user may edit their own JS subpages.
	** viewmywatchlist controls whether a user may view their watchlist.
	** editmywatchlist controls whether a user may edit their watchlist.
	** viewmyprivateinfo controls whether a user may access their private
	information (e.g. registered email address, real name).
	** editmyprivateinfo controls whether a user may change their private
	information.
	** editmyoptions controls whether a user may change their preferences.
	* Add new hook AbortTalkPageEmailNotification, this will be used to determine
	whether to send the regular talk page email notification
	* Action classes registered in $wgActions are now also supported in the form of
	a callback (which returns an instance of Action) instead of providing the name
	of a subclass of Action.
	* (bug 46513) Vector: Add the collapsibleTabs script from the Vector extension.
	* Added $wgRecentChangesFlags for defining new flags for RecentChanges and
	watchlists.
	* (bug 40518) mw.toolbar: Implemented mw.toolbar.addButtons for adding multiple
	button objects in one call.
	* Rights used for the default protection levels ('sysop' and 'autoconfirmed')
	are now used just for that purpose, instead of overloading other rights. This
	allows easy granting of the ability to edit sysop-protected pages without
	also granting the ability to protect and unprotect.
	* (bug 48256) Make brackets in section edit links accessible to CSS.
	They are now wrapped in <span class="mw-editsection-bracket" />.
	* (bug 8480) Allow handler specific parameters in galleries (like page number)
	* jquery.client: Add detection for Opera 15 and Internet Explorer 11.
	* Change tags (used by the AbuseFilter extension) are now shown on diff pages.
	* Change tag lists (shown on recent changes, watchlist, user contributions,
	history pages, diff pages) now include a link to Special:Tags to distinguish
	them from edit summaries.
	* Added a new method and hook, User::isEveryoneAllowed() and
	UserIsEveryoneAllowed, for use in situations where a "does everyone have this
	right?" check is used to avoid more expensive checks.
	* (bug 14431) Display "(No difference)" instead of an empty diff (when comparing
	revisions in the history or when previewing changes while editing).
	* New hook 'IsUploadAllowedFromUrl' is added which can be used to intercept
	uploads by URL, useful for blacklisting specific URLs
	* (bug 21912) Watchlist token implementation has been refactored and
	Special:ResetTokens was added to allow users to reset their tokens
	instead of presenting them in Preferences.
	* Special:PrefixIndex now lets you strip the searched prefix from the displayed
	titles. Given a list of articles named Bug1, Bug2, you can now transclude the
	list of bug numbers using: {{Special:PrefixIndex/Bug\|stripprefix=1}}.
	The special page form received a new checkbox matching that option.
	* (bug 23580) Implement javascript callback interface "mw.hook".
	* (bug 30713) New mw.hook "wikipage.content".
	* (bug 40430) jquery.placeholder gets a new parameter to set the attribute value
	to be used.
	* $wgHTCPMulticastRouting renamed $wgHTCPRouting since it accepts unicast.
	* $wgHTCPRouting rules can now be passed an array of hosts/ports to send purge
	too. Can be used whenever several multicast group could be interested by a
	specific purge.
	* (bug 25931) Add Special:RandomInCategory.
	* mediawiki.util: addPortletLink now supports passing a jQuery object as
	nextnode.
	* <wbr> can now be used inside WikiText.
	* WebResponse::setcookie is much more featureful. Callers using PHP's
	setcookie() or setrawcookie() should begin using this instead.
	* New hook WebResponseSetCookie, called from WebResponse::setcookie().
	* New hook ResetSessionID, called when the session id is reset.
	* Add a mode parameter to <gallery> tag with potential options of "traditional",
	"nolines", "packed", "packed-overlay", or "packed-hover".
	* (bug 47399) A success message is now displayed after changing the password.
	* Make thumb.php give HTTP redirects for file redirects
	* (bug 30607) Special:ListFiles can now show old versions of files. Additionally
	Special:AllMyUploads was introduced so the user can get a list of all things
	they have ever uploaded, even if it was subsequently overridden.
	* Introduced Special:MyFiles and Special:AllMyFiles as an alias for
	Special:MyUploads and Special:AllMyUploads respectively.
	* IPv6 addresses in X-Forwarded-For headers are now normalised before checking
	against allowed proxy lists.
	* Add deferrable update support for callback/closure.
	* Add TitleMove hook before page renames.
	* Revision deletion backend code is moved out of SpecialRevisiondelete
	* Added {{REVISIONSIZE}} variable to get the current size of a revision.
	* Add support for the LESS stylesheet language to ResourceLoader. LESS is a
	stylesheet language that compiles into CSS. ResourceLoader file modules may
	include LESS style files; ResourceLoader will compile these files into CSS
	before sending them to the client.
	** The $wgResourceLoaderLESSVars configuration variable is an associative array
	mapping variable names to string CSS values. These variables are considered
	declared for all LESS files. Additional variables may be registered by
	adding keys to the array.
	** $wgResourceLoaderLESSFunctions is an associative array of custom LESS
	function names to PHP callables. See
	<http://leafo.net/lessphp/docs/#custom_functions>
	for more details regarding custom functions.
	** $wgResourceLoaderLESSImportPaths is an array of file system paths. Files
	referenced in LESS '@import' statements are looked up here first.
	* ResourceLoader supports hashes as module cache invalidation trigger (instead
	of or in addition to timestamps).
	* Added $wgExtensionEntryPointListFiles for use in mergeMessageFileList.php.
	* Added a hook, APIQuerySiteInfoStatisticsInfo, to allow extensions to modify
	the output of the API query meta=siteinfo&siprop=statistics
	* Primary keys have been added to both the archive table and the externallinks
	tables.
	* Added $wgEnableParserLimitReporting to control whether the NewPP limit report
	is output in a HTML comment.
	* The 'UnwatchArticle' and 'WatchArticle' hooks now support a Status object
	instead of just a boolean return value to abort the hook.
	* Added a hook, SpecialWatchlistGetNonRevisionTypes, to allow extensions
	with custom recentchanges entries to hook into the Watchlist without
	clobbering each other.
	* A hidden, empty input field was added to the edit form, and any edit that
	fills it in will be rejected. This prevents against the simplest form of
	spambots. Previously in the "SimpleAntiSpam" extension by Ryan Schmidt.
	* populateRevisionLength.php maintenance script updated to also populate
	archive.ar_len field.
	* (bug 43571) DatabaseMySQLBase learned to list views, optionally filtered by a
	prefix. Also fixed PHPUnit test suite when using a MySQL backend containing
	views.

	=== Bug fixes in 1.22 ===
	* (bug 47271) $wgContentHandlerUseDB should be set to false during the upgrade
	* Disable Special:PasswordReset when $wgEnableEmail is false. Previously one
	could still navigate to the page by entering the URL directly.
	* (bug 47138) Fixed a fatal error when a blocked user tries to automatically
	create an account on login due external authentication in some circumstances.
	* (bug 23393) HTML <hN> headings containing line breaks are now handled
	correctly.
	* (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
	is now non-significant and not preserved in the HTML output.
	* (bug 47218) Special:BlockList now handles correctly user names with spaces
	when passed as subpage.
	* Pager's properly validate which fields are allowed to be sorted on.
	* mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
	Support for Mac "option" was added in 1.16, but the regex was never updated.
	* (bug 46768) Usernames of blocking users now display correctly, even if
	numeric.
	* (bug 39590) Self-transclusions now show the most up to date result always
	after save instead of being a revision behind.
	* A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
	strings will now start with digits 0 and 8-f as often as they should.
	* (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
	* (bug 41545) Allow <kbd>, <samp>, and <var> to be nested like allowed in html.
	* PLURAL magic word no longer causes a PHP notice when no matching form exists.
	* (bug 36641) Patrol page links no longer show on non-existent revisions.
	* (bug 35810) Pages not linked from Special:RecentChanges or Special:NewPages
	are patrollable now.
	* (bug 30213) JavaScript for search suggestions is now disabled when the API
	is disabled, and AJAX patrolling and watching are now disabled when use of
	the write API is not allowed.
	* (bug 48294) API: Fix chunk upload async mode.
	* (bug 46749) Broken files tracking category removed from pages if an image
	with that name is uploaded.
	* (bug 14176) System messages that are empty were previously incorrectly treated
	as non-existent, causing a fallback to the default. This stopped users from
	overriding system messages to make them blank.
	* (bug 48319) action=parse no longer returns an error if passed none of 'oldid',
	'pageid', 'page', 'title', and 'text' (e.g. if only passed 'summary'). A
	warning will instead be issued if 'title' is non-default, unless no props are
	requested.
	* Special:Recentchangeslinked will now include upload log entries
	* (bug 41281) Fixed ugly output if file size could not be extracted for
	multi-page media.
	* (bug 50315) list=logevents API module will now output log entries by anonymous
	users.
	* (bug 38911) Handle headers with rowspan in jquery.tablesorter
	* (bug 658) Converted the table of contents on wiki pages from <table> to <div>
	and adjusted skin CSS accordingly. The CSS was carefully crafted to be
	backwards-compatible in all reasonable cases (uses of the __TOC__ magic word,
	the #toc CSS id and the .toc CSS class). However, particularly bad abuse of
	the id or the class can possibly break.
	* CSSJanus now supports rgb, hsl, rgba, and hsla color syntaxes.
	* Special:Listfiles can no longer be sorted by image name when filtering
	by user in miser mode.
	* (bug 49074) CSSJanus: Handle values of border-radius correctly.
	* Handle relative inclusions ({{../name}}) in main namespace with subpages
	enabled correctly (previously MediaWiki tried to include Template:Parent/name
	instead of just Parent/name).
	* Added $wgAPIUselessQueryPages to allow extensions to flag their query pages
	for non-inclusion in ApiQueryQueryPages.
	* (bug 50870) mediawiki.notification: Notification area should remain visible
	when scrolled down.
	* (bug 13438) Special:MIMESearch no longer an expensive special page.
	* (bug 48342) Fixed a fatal error when $wgValidateAllHtml is set to true and
	the function apache_request_headers() function is not available.
	* (bug 33399) LivePreview: Re-run wikipage content handlers
	(jquery.makeCollapsible, jquery.tablesorter) after preview content is loaded.
	* (bug 51891) Fixed PHP notice on Special:PagesWithProp when no properties
	are defined.
	* (bug 52006) Corrected documentation of $wgTranscludeCacheExpiry.
	* (bug 52077) The APIEditBeforeSave hook is giving the content of the whole
	revision as second argument now, rather than just the current section.
	* (bug 49694) $wgSpamRegex is now also applied on the new section headline text
	adding a new topic on a page
	* (bug 41756) Improve treatment of multiple comments on a blank line.
	* (bug 51064) Purge upstream caches when deleting file assets.
	* (bug 39012) File types with a mime that we do not know the extension for
	can no longer be uploaded as an extension that we do know the mime type
	for.
	* (bug 51742) Add data-sort-value for better sorting of hitcounts Special:Tags
	* (bug 26811) On DB error pages, server hostnames are now hidden when both
	$wgShowHostnames and $wgShowSQLErrors are false.
	* (bug 6200) line breaks in <blockquote> are handled like they are in <div>
	* (bug 14931) Default character set now set to 'utf8' when a new MySQL
	database is created.
	* (bug 47191) Fixed "Column 'si_title' cannot be part of FULLTEXT index"
	MySQL error when installing using the binary character set option.
	* (bug 45288) Support mysqli PHP extension
	* (bug 55818) BREAKING CHANGE: Removed undocumented 'Debug' hook in wfDebug.
	This resolves an infinite loop when using $wgDebugFunctionEntry = true.
	* (bug 56707) Correct tooltip of "Next n results" on query special pages.
	* (bug 56770) mw.util.addPortletLink: Check length before access array index.

	=== API changes in 1.22 ===
	* (bug 25553) The JSON output formatter now leaves forward slashes unescaped
	to improve human readability of URLs and similar strings. Also, a "utf8"
	option is now provided to use UTF-8 encoding instead of hex escape codes
	for most non-ASCII characters.
	* (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
	parameter has had no effect since MediaWiki 1.16, and so its removal is
	unlikely to impact existing clients.
	* (bug 47216) action=query&meta=siteinfo&siprop=skins will now indicate which
	skin is the default and which are unusable (e.g. listed in $wgSkipSkins).
	* (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
	to action=feedwatchlist.
	* WDDX formatted output will actually be formatted (and normal output will no
	longer be), and will no longer choke on booleans.
	* action=opensearch no longer silently ignores the format parameter.
	* action=opensearch now supports format=jsonfm.
	* list=usercontribs&ucprop=ids will now include the parent revision id.
	* BREAKING CHANGE: action=parse no longer returns all langlinks for the page
	with prop=langlinks by default. The new effectivelanglinks parameter will
	request that the LanguageLinks hook be called to determine the effective
	language links.
	* BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
	apply the new LanguageLinks hook, and thus only consider language links
	stored in the database.
	* (bug 47219) Allow specifying change type of Wikipedia feed items
	* prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
	* prop=info now adds the content model and page language of the title.
	* New upload log entries will now contain information on the relevant
	image (sha1 and timestamp).
	* (bug 49239) action=parse now can parse in preview and section preview modes.
	* (bug 49259) action=patrol now accepts revision ids.
	* (bug 48129) list=blocks&bkip= now correctly handles IPv6 CIDR ranges and
	honors $wgBlockCIDRLimit. Note any clients passing invalid values to bkip
	will now receive an error, rather than the previous behavior listing all
	user blocks.
	* (bug 48201) action=parse&text=foo now assumes wikitext if no title is given,
	rather than using the content model of the page "API".
	* action=watch no longer silently ignores hook abort.
	* (bug 50785) action=purge with forcelinkupdate=1 no longer queues refreshLinks
	jobs in the job queue for link table updates of pages that use the given page
	as a template. Instead, forcerecursivelinkupdate=1 is introduced and should
	be used if that behaviour is desirable.
	* The 'debugLog' property (enabled by $wgDebugToolbar) no longer sets the log
	entry values through ApiResult::content but directly. This changes the JSON
	output from an array of objects with content in '*' to an array of strings
	with the content.
	* (bug 51342) prop=imageinfo iicontinue now contains the dbkey, not the text
	version of the title.
	* (bug 52538) action=edit will now use empty text instead of the contents
	of section 0 when passed prependtext or appendtext with section=new.
	* Support for the 'gettoken' parameter to action=block and action=unblock,
	deprecated since 1.20, has been removed.
	* (bug 49090) Token-getting functions will fail when using jsonp callbacks.
	* (bug 52699) action=upload returns normalized file name on warning
	"exists-normalized" instead of filename to be uploaded to.
	* (bug 53884) action=edit will now return an error when the specified section
	does not exist in the page.
	* Added meta=filerepoinfo API module for getting information about foreign
	file repositories, and related ForeignAPIRepo methods getInfo and getApiUrl.
	* The new query module list=allfileusages to enumerate file usages was added.

	=== Languages updated in 1.22 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Bugzilla reports.

	* Batak Toba (bbc-latn) added.
	* (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.

	=== Other changes in 1.22 ===
	* BREAKING CHANGE: Implementation of MediaWiki's JS and JSON value encoding
	has changed:
	** MediaWiki no longer supports PHP installations in which the native JSON
	extension is missing or disabled.
	** XmlJsCode objects can no longer be nested inside objects or arrays.
	(For Xml::encodeJsCall(), this individually applies to each argument.)
	** The sets of characters escaped by default, along with the precise escape
	sequences used, have changed (except for the Xml::escapeJsString()
	function, which is now deprecated).
	* BREAKING CHANGE: The Services_JSON class has been removed. If necessary,
	be sure to upgrade affected extensions at the same time (e.g. Collection).
	* redirect.php was removed. It was unused.
	* ClickTracking integration was dropped from the mediaWiki.user.bucket
	JavaScript function. The 'tracked' option is now ignored.
	* BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
	were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
	LegacyTemplate classes that supported them were removed as well and are now a
	part of the Nostalgia extension.
	* Event namespace used by jquery.makeCollapsible has been changed from
	'mw-collapse' to 'mw-collapsible' for consistency with the module name.
	* BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed,
	along with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
	$wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
	use AuthPlugin for external authentication/authorization needs.
	* The Quickbar feature of the legacy skin model and the last remnants of it
	throughout the code base have been removed.
	* Externaledit/externaldiff preference was removed. Very few users used this
	feature, and improper configuration can actually prevent a user from editing
	* Calling Linker methods using a skin will now output deprecation warnings.
	* (bug 46680) "Return to" links are no longer tagged with rel="next".
	* BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
	accesskey character is now $6 instead of $5.
	* HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
	added.
	* A new Special:Redirect page was added, providing lookup by revision ID,
	user ID, or file name. The old Special:Filepath page was reimplemented
	to redirect through Special:Redirect.
	* Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
	* Support for XHTML 1.0 has been removed. MediaWiki now only outputs (X)HTML5.
	* wikibits: User-agent related globals have been deprecated. The following
	properties now default to false and emit mw.log.warn: is_gecko, is_chrome_mac,
	is_chrome, webkit_version, is_safari_win, is_safari, webkit_match, is_ff2,
	ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs, opera7_bugs, opera6_bugs,
	is_opera_95, is_opera_preseven, is_opera, and ie6_bugs.
	* (bug 48276) MediaWiki will now flash a confirmation message upon successfully
	editing a page.
	* (bug 40785) mediawiki.legacy.ajax has been marked as deprecated. The following
	properties now emit mw.log.warn when accessed: sajax_debug, sajax_init_object,
	sajax_do_call and wfSupportsAjax.
	* BREAKING CHANGE: meta keywords are no longer supported. A
	<meta name="keywords" will no longer be output and OutputPage::addKeyword no
	longer exists.
	* Methods Title::userCanEditCssSubpage and Title::userCanEditJsSubpage,
	deprecated since 1.19, have been removed.
	* (bug 50134) Hook functions are no longer required to return a value. When a
	hook function does not return a value (or when it returns an explicit null),
	processing continues. To abort the hook, a hook function must return an
	explicit, boolean false or a string error message. Other falsey values are
	tantamount to a 'return true' in earlier versions of MediaWiki.
	* BREAKING CHANGE: The EditSectionLink hook was removed after being
	deprecated since MediaWiki 1.14. Use DoEditSectionLink instead.
	* (bug 48256) The 'editsection-brackets' optional message was removed.
	Section edit links' brackets can now be customized using CSS by
	styling span.mw-editsection-bracket.
	* The usePatrol function in ChangesList has been marked as deprecated.
	* (bug 50785) A "null edit", that is, a save action in which no changes to the
	page text are made and no revision recorded, will no longer send refreshLinks
	jobs to the job table to update pages which use the edited page as a template.
	* The LivePreviewPrepare and LivePreviewDone events triggered on "jQuery( mw )"
	have been deprecated in favour of using mw.hook.
	* The 'showjumplinks' user preference has been removed, jump links are now
	always included.
	* Methods RecentChange::notifyRC2UDP, RecentChange::sendToUDP, and
	RecentChange::cleanupForIRC have been deprecated, as it is now the
	responsibility of classes implementing the RCFeedFormatter and RCFeedEngine
	interfaces to implement the formatting and delivery for recent change
	notifications.
	* SpecialPrefixindex methods namespacePrefixForm() and showPrefixChunk() have
	been made protected. They were accepting form variance arguments, this is now
	using properties in the SpecialPrefixindex class.
	* (bug 50310) BREAKING CHANGE: wikibits: Drop support for mwCustomEditButtons.
	It defaults to an empty array and emits mw.log.warn when accessed.
	* BREAKING CHANGE: Special:Disambiguations has been removed from MediaWiki core.
	Functions related to disambiguation pages are now handled by the Disambiguator
	extension (https://www.mediawiki.org/wiki/Extension:Disambiguator) (bug
	35981).
	* BREAKING CHANGE: The 'mediawiki.legacy.wikiprintable' module has been removed.
	The skins/common/wikiprintable.css file no longer exists. Return value of
	Skin#commonPrintStylesheet is ignored. Please use the
	'mediawiki.legacy.commonPrint' module instead or base your skin on
	SkinTemplate.
	* (bug 49629) The hook ExtractThumbParameters has been deprecated in favour
	of media handler overriding MediaHandler::parseParamString.
	* (bug 46512) The collapsibleNav feature from the Vector extension has been
	moved to the Vector skin in core.
	* SpecialRecentChanges::addRecentChangesJS() function has been renamed
	to addModules() and made protected.
	* Methods WatchAction::doWatch and WatchAction::doUnwatch now return a Status
	object instead of a boolean.
	* Information boxes (CSS classes errorbox, warningbox, successbox) have been
	made more subtle.
	* BREAKING CHANGE: The module 'mediawiki.legacy.IEFixes' has been removed as it
	was unused. The file skins/common/IEFixes.js remains but is only used by
	wikibits. The file never contained any re-usable components. To use it in a
	skin, load 'mediawiki.legacy.wikibits' (which IEFixes depends on) and that
	will import IEFixes automatically if user agent conditions are met.
	* Code specific to the Math extension was marked as deprecated.
	* mediawiki.util: mw.util.wikiGetlink has been renamed to getUrl. (The old name
	still works, but is deprecated.)

	* Deprecated $wgAllowRealName is removed. Use $wgHiddenPrefs[] = 'realname'
	instead.
	* (bug 39957) Added $wgUnwatchedPageThreshold, specifying minimum count
	of page watchers required for the number to be accessible to users
	without the unwatchedpages permission.
	* $wgBug34832TransitionalRollback has been removed.
	* (bug 29472) $wgUseDynamicDates has been removed and its functionality
	disabled.

	=== New features in 1.21 ===
	* (bug 38110) Schema changes (adding or dropping tables, indices and
	fields) can be now be done separately from other changes that
	update.php makes. This is useful in environments that use database
	permissions to restrict schema changes but allow the DB user that
	MediaWiki normally runs as to perform other changes that update.php
	makes. Schema changes can be run separately. See the file UPGRADE
	for more information.
	* (bug 34876) jquery.makeCollapsible has been improved in performance.
	* Added ContentHandler facility to allow extensions to support other content
	than wikitext. See docs/contenthandler.txt for details.
	* New feature was developed for showing high-DPI thumbnails for high-DPI mobile
	and desktop displays (configurable with $wgResponsiveImages).
	* Added new backend to represent and store information about sites and site
	specific configuration.
	* jQuery upgraded from 1.8.2 to 1.8.3.
	* jQuery UI upgraded from 1.8.23 to 1.8.24.
	* Added separate fa_sha1 field to filearchive table. This allows sha1
	searches with the api in miser mode for deleted files.
	* Add initial and programmatic sorting for tablesorter.
	* Add the event "sortEnd.tablesorter", triggered after sorting has completed.
	* The Job system was refactored to allow for different backing stores for
	queues as well as cross-wiki access to queues, among other things. The schema
	for the DB queue was changed to support better concurrency and reduce
	deadlock errors.
	* Added ApiQueryORM class to facilitate creation of query API modules based on
	tables that have a corresponding ORMTable class.
	* (bug 40876) Icon for PSD (Adobe Photoshop) file types.
	* (bug 40641) Implemented Special:Version/Credits with a list of contributors.
	* (bug 7851) Implemented one-click AJAX patrolling.
	* The <data>, <time>, <meta>, and <link> elements are allowed within WikiText
	for use with Microdata.

	* Added ParserCloned hook for when the Parser object is cloned.
	* Added AlternateEditPreview hook to allow extensions to replace the page
	preview from the edit page.
	* Added EditPage::showStandardInputs:options hook to allow extensions to add
	new fields to the "editOptions" area of the edit form.
	* Upload stash DB schema altered to improve upload performance.
	* The following global functions are now reporting deprecated warnings in
	debug mode: wfMsg, wfMsgNoTrans, wfMsgForContent, wfMsgForContentNoTrans,
	wfMsgReal, wfMsgGetKey, wfMsgHtml, wfMsgWikiHtml, wfMsgExt, wfEmptyMsg. Use
	the Message class, or the global method wfMessage.
	* Added $wgEnableCanonicalServerLink, off by default. If enabled, a
	<link rel=canonical> tag is added to every page indicating the correct server
	to use.
	* Debug message emitted by wfDebugLog() will now be prefixed with the group
	name when its logged to the default log file. That is the case whenever the
	group has no key in wgDebugLogGroups, that will help triage the default log.
	* (bug 24620) Add types to LogFormatter.
	* jQuery JSON upgraded from 2.3 to 2.4.0.
	* Added GetDoubleUnderscoreIDs hook, for modifying the list of magic words.
	* DatabaseUpdater class has two new methods to ease extensions schema changes:
	dropExtensionIndex and renameExtensionIndex.
	* New preference type - 'api'. Preferences of this type are not shown on
	Special:Preferences, but are still available via the action=options API.
	* (bug 39397) Hide rollback link if a user is the only contributor of the page.
	* $wgPageInfoTransclusionLimit limits the list size of transcluded articles
	on the info action. Default is 50.
	* Added action=createaccount to allow user account creation.
	* (bug 40124) action=options API also allows for setting of arbitrary
	preferences, provided that their names are prefixed with 'userjs-'. This
	officially reenables the feature that was undocumented and defective
	in MW 1.20 (saving preferences using Special:Preferences cleared any
	additional fields) and which has been disabled in 1.20.1 as a part of
	a security fix (bug 42202).
	* Added option to specify "others" as author in extension credits using
	"..." as author name.
	* Added the ability to limit the wall clock time used by shell processes,
	as well as the CPU time. Configurable with $wgMaxShellWallClockTime.
	* Allow memory of shell subprocesses to be limited using Linux cgroups
	instead of ulimit -v, which tends to cause deadlocks in recent versions
	of ImageMagick. Configurable with $wgShellCgroup.
	* Added $wgWhitelistReadRegexp for regex whitelisting.
	* (bug 5346) Categories that are redirects will be displayed italic in
	the category links section at the bottom of a page.
	* (bug 43915) New maintenance script deleteEqualMessages.php.
	* You can now create checkbox option matrices through the HTMLCheckMatrix
	subclass in HTMLForm.
	* WikiText now permits the use of WAI-ARIA's role="presentation" inside of
	html elements and tables. This allows presentational markup, especially
	tables. To be marked up as such.
	* maintenance/sql.php learned the --cluster option. Let you run the script
	on some external cluster instead of the primary cluster for a given wiki.
	* (bug 20281) test the parsing of inline URLs.
	* Added Special:PagesWithProp, which lists pages using a particular page
	property.
	* Implemented language-specific collations for category sorting for 67 languages
	based in latin, greek and cyrillic alphabets. This allows one to finally get
	articles to be correctly sorted on category pages. They are named
	'uca-<langcode>', where <langcode> is one of: af, ast, az, be, bg, br, bs, ca,
	co, cs, cy, da, de, dsb, el, en, eo, es, et, eu, fi, fo, fr, fur, fy, ga, gd,
	gl, hr, hsb, hu, is, it, kk, kl, ku, ky, la, lb, lt, lv, mk, mo, mt, nl, no,
	oc, pl, pt, rm, ro, ru, rup, sco, sk, sl, smn, sq, sr, sv, tk, tl, tr, tt, uk,
	uz, vi.
	* Added 'CategoryAfterPageAdded' and 'CategoryAfterPageRemoved' hooks.
	* Added 'HistoryRevisionTools' and 'DiffRevisionTools' hooks.
	* Added 'SpecialSearchResultsPrepend' and 'SpecialSearchResultsAppend' hooks.
	* (bug 33186) Add image rotation api "imagerotate"
	* (bug 34040) Add "User rights management" link on user page toolbox.
	* (bug 45526) Add QUnit assertion helper "QUnit.assert.htmlEqual" for asserting
	structual equality of HTML (ignoring insignificant differences like
	quotmarks, order and whitespace in the attribute list).
	* (bug 23393) HTML <hN> headings containing line breaks are now handled
	correctly.
	* (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
	is now non-significant and not preserved in the HTML output.

	=== Bug fixes in 1.21 ===
	* (bug 40353) SpecialDoubleRedirect should support interwiki redirects.

	* (bug 34960) Drop unused fields rc_moved_to_ns and rc_moved_to_title from
	recentchanges table.
	* (bug 32951) Do not register internal externals with absolute protocol,
	when server has relative protocol.
	* (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
	method requests, we now send a Host header by default, for Varnish
	compatibility. This also works with Squid in reverse-proxy mode. If you wish
	to support Squid configured in forward-proxy mode, set
	$wgSquidPurgeUseHostHeader to false.
	* (bug 37020) sql.php with readline eats semicolon.
	* (bug 11748) Properly handle optionally-closed HTML tags when Tidy is
	disabled, and don't wrap HTML-syntax definition lists in paragraphs.

	* (bug 41793) Contribution links to users with 0 edits on Special:ListUsers
	didn't show up red.
	* (bug 41899) A PHP notice no longer occurs when using the "rvcontinue" API
	parameter.
	* (bug 42036) Account creation emails now contain canonical (not
	protocol-relative) URLs.
	* (bug 41990) Fix regression: API edit with redirect=true and lacking
	starttimestamp and basetimestamp should not cause an edit conflict.
	* (bug 41706) EditPage: Preloaded page should be converted if possible and
	needed.
	* (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
	actually sorted.

	* (bug 36053) Log in "returnto" feature forgets query parameters if no
	title parameter was specified.
	* (bug 42410) API action=edit now returns correct timestamp for the new edit.
	* (bug 14901) Email notification mistakes log action for new page creation.
	Enotif no longer sends "page has been created" notifications for some log
	actions. The following events now have a correct message: page creation,
	deletion, move, restore (undeletion), change (edit). Parameter
	$CHANGEDORCREATED is deprecated in 'enotif_body' and scheduled for removal in
	MediaWiki 1.23.
	* (bug 457) In the sidebar of Vector, CologneBlue, Monobook, and Monobook-based
	skins, the heading levels have been changed from (variously per skin)
	<h4>, <h5> or <h6> to only <h3>s, with a <h2> hidden heading above them.
	If you are styling or scripting the headings in a custom way, this change
	will require updates to your site's CSS or JS.
	* (bug 41342) jquery.suggestions should cancel any active (async) fetches
	before it triggers another fetch.
	* (bug 42184) $wgUploadSizeWarning missing second variable.

	History page.
	* (bug 42949) API no longer assumes all exceptions are MWException.
	* (bug 41733) Hide "New user message" (.usermessage) element from printable
	view.
	* (bug 39062) Special:Contributions will display changes that don't have
	a parent id instead of just an empty bullet item.
	* (bug 37209) "LinkCache doesn't currently know about this title" error fixed.

	=== API changes in 1.21 ===
	* prop=revisions can now report the contentmodel and contentformat.
	See docs/contenthandler.txt.
	* action=edit and action=parse now support contentmodel and contentformat
	parameters to control the interpretation of page content.
	See docs/contenthandler.txt for details.
	* (bug 35693) ApiQueryImageInfo now suppresses errors when unserializing
	metadata.
	* (bug 40111) Disable minor edit for page/section creation by API.

	the same query. When both are present, 'from' is simply ignored.
	* list=alllinks & alltransclusions now allow 'unique' in generators, to yield
	a list of all link/template target pages instead of source pages.
	* BREAKING CHANGE: list=logevents output format changed for details of some log
	types. Specifically, details that were formerly reported under a key like
	"4::foo" will now be reported under a key of simply "foo".
	* BREAKING CHANGE: '??_badcontinue' error code was changed to '??badcontinue'
	for all query modules.
	* ApiQueryBase adds 'badcontinue' error code if module has 'continue' parameter.
	* (bug 35885) Removed version parameter and all getVersion() methods.

	result.
	* action=help supports generalized submodules (modules=query+value),
	querymodules obsolete
	* ApiQueryImageInfo continuation is more reliable. The only major change is
	that the imagerepository property will no longer be set on page objects not
	processed in the current query (i.e. non-images or those skipped due to
	iicontinue).
	* Add supports for all pageset capabilities - generators, redirects,
	converttitles to action=purge and action=setnotificationtimestamp.
	* (bug 43251) prop=pageprops&ppprop= now accepts multiple props to query.
	* ApiQueryImageInfo will now limit the number of calls to File::transform made
	in any one query. If there are too many, iicontinue will be returned.

	link trails and link prefixes. Added for Parsoid support.
	* Added an API query module list=pageswithprop, which lists pages using a

	results
	* (bug 44909) API parameters may now be marked as type "upload", which is now

	an error during parameter validation if the parameter is given but not
	recognized as an uploaded file.
	* (bug 44244) prop=info may now return the number of people watching each page.
	* (bug 33304) list=allpages will no longer return duplicate entries when
	querying protection.
	* (bug 33304) list=allpages will now find really old indefinite protections.
	* (bug 45937) meta=allmessages will report a syntactically invalid lang as a
	proper error instead of as an uncaught exception.
	* (bug 25325) added support for wlshow filtering (bots/anon/minor/patrolled)
	to action=feedwatchlist
	* WDDX formatted output will actually be formatted (and normal output will no
	longer be), and will no longer choke on booleans.

	=== API internal changes in 1.21 ===
	* For debugging only, a new global $wgDebugAPI removes many API restrictions
	when true.
	Never use on the production servers, as this flag introduces security holes.
	Whenever enabled, a warning will also be added to all output.
	* ApiModuleManager now handles all submodules (actions,props,lists) and
	instantiation
	* Query stores prop/list/meta as submodules
	* ApiPageSet can now be used in any action to process titles/pageids/revids or
	any generator.

	with only the first one keeping its meaning. ApiPageSet is now derived from
	ApiBase.
	* BREAKING CHANGE: ApiQuery::newGenerator() and executeGeneratorModule() were
	deleted.
	* ApiQueryGeneratorBase::setGeneratorMode() now requires a pageset param.
	* $wgAPIGeneratorModules is now obsolete and will be ignored.
	* Added flags ApiResult::OVERRIDE and ADD_ON_TOP to setElement() and addValue()
	* Internal API calls will now include <warnings> in case of unused parameters

	=== Languages updated in 1.21 ===

	MediaWiki supports over 350 languages. Many localisations are updated
	regularly. Below only new and removed languages are listed, as well as
	changes to languages because of Bugzilla reports.

	* South Azerbaijani (azb) added.
	* (bug 30040) Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').
	* (bug 45436) Autonym for pi (Pali) is now 'पालि' (was ''पाळि').
	* (bug 34977) Now formatted numbers in Spanish use space as separator
	for thousands, as mandated by the Real Academia Española.
	* (bug 35031) Kurdish formatted numbers now use period and comma
	as separators for thousands and decimals respectively.

	=== Other changes in 1.21 ===
	* BREAKING CHANGE: (bug 44385) Removed the jquery.collapsibleTabs module and
	moved it to the Vector extension. It was entirely Vector-extension-specific,
	deeply interconnected with the extension, and this functionality really
	belongs to the extension instead of the skin anyway. In the unlikely case you
	were using it, you have to either copy it to your extension, or install the
	Vector extension (and possibly disable its features using config settings if
	you don't want them).
	* Experimental IBM DB2 support was removed due to lack of interest and
	maintainership
	* BREAKING CHANGE: Filenames of maintenance scripts were standardized into
	lowerCamelCase format, and made more explicit:
	- clear_stats.php -> clearCacheStats.php
	- clear_interwiki_cache.php -> clearInterwikiCache.php
	- initStats.php -> initSiteStats.php
	- proxy_check.php -> proxyCheck.php
	- stats.php -> showCacheStats.php
	- showStats.php -> showSiteStats.php.
	Class names were renamed accordingly:
	- clear_stats -> ClearCacheStats
	- InitStats -> InitSiteStats
	- CacheStats -> ShowCacheStats
	- ShowStats -> ShowSiteStats.
	* BREAKING CHANGE: (bug 38244) Removed the mediawiki.api.titleblacklist module
	and moved it to the TitleBlacklist extension.

	and/or wrapping them in a callback to mw.loader.using.

	and $wgServer

	* (bug 32126) Fix 1.18 regression in watchlist editor when items already removed
	from watchlist.

	=== Configuration changes in 1.18 ===
	* The WantedPages::getSQL hook has been removed and replaced with
	WantedPages::getQueryInfo. This may break older extensions.
	* The SkinTemplateBuildContentActionUrlsAfterSpecialPage,
	SkinTemplateContentActions and SkinTemplateTabs hooks have been removed in
	favor of SkinTemplateNavigation and SkinTemplateNavigation::SpecialPage.
	* $wgUseCombinedLoginLink controls whether to output a combined
	login / create account link in the personal bar, or to output separate login
	and create account links.
	* Skin names are no longer created based on a ucfirst version of the key in
	$wgValidSkinNames but now the value. This means for
	$wgValidSkinNames["monobook"] = "MonoBook"; the skin loader will no longer try
	loading SkinMonobook and will instead load SkinMonoBook.
	* $wgMaxUploadSize may now be set to an array to specify the upload size limit
	per upload type.
	* $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set
	$wgAPICacheHelpTimeout = 0;
	* OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed
	by the page, but $wgAllowUserJs is set to false.
	* Pure "Skin" class based custom skins are no longer supported, all custom skins
	should be put together using SkinTemplate and BaseTemplate or QuickTemplate.
	* The transliteration for passwords in case they were migrated from an old
	Latin-1 install (previous to MediaWiki 1.5) is now only done for wikis with
	$wgLegacyEncoding set.
	* (bug 27508) Add $wgSVGMetadataCutoff to limit the maximum amount of an SVG we
	look at when finding metadata to prevent excessive resource usage.
	* $wgSysopUserBans and $wgSysopRangeBans (deprecated in 1.17) are now removed.
	Use $wgBlockCIDRLimit = array( 'IPv4' => 43, 'IPv6' => 128 ) to achieve the
	same functionality as $wgSysopRangeBans; you can use the BlockIp hook to
	replicate $wgSysopUserBans functionality.
	* The options on the block form have been standardised such that checking a box
	makes the block 'more serious'; so while "check to prevent account creation"
	and "check to enable autoblock" remain the same, "check to allow user-talk
	edit" is reversed to "check to disable user-talk edit", and "check to block
	anon-only" becomes "check to block logged-in users too". The default settings
	remain the same.
	* Most of the field names on the Special:Block form have been changed, which
	will probably break screen-scraping bots.
	* (bug 26866) The 'trackback' right is no longer granted to sysops by default.
	$wgUseTrackbacks is already false by default.
	* (bug 17009) the hiddenStructure CSS class, a highly hackish way of at least
	appearing to hide article elements, has been removed. Use the
	ParserFunctions extension to actually remove unwanted elements from the
	output.
	* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable
	math conversion after upgrading, obtain the Math extension from SVN or from
	https://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php:
	require_once "$IP/extensions/Math/Math.php";
	* $wgProfiler is now a configuration array, see StartProfiler.sample for
	details.
	* $wgProfiling has been removed.
	* The spyc library is now no longer included in phase3.
	* (bug 28343) Unused preferences contextlines/contextchars have been removed
	* $wgSkinExtensionFunctions has been removed. Use $wgExtensionFunctions instead.
	* $wgProto has been removed. You now only need to set $wgServer to change the
	URL protocol.
	* $wgRateLimitsExcludedGroups (deprecated in 1.13) has been removed.
	* $wgInputEncoding and $wgOutputEncoding (deprecated in 1.5) have now been
	removed.
	* $wgAllowUserSkin (deprecated in 1.16) has now been removed.
	* $wgExtraRandompageSQL (deprecated in 1.16) has now been removed.
	* LogReader and LogViewer classes (deprecated in 1.14) have now been removed.
	* (bug 26033) Added $wgArticleCountMethod to select the method to use to say
	whether a page is an article or not. $wgUseCommaCount is now deprecated.
	* $wgEnableDublinCoreRdf and $wgEnableCreativeCommonsRdf no longer work in core,
	and the functionality has been moved to the relevant extensions. See
	https://www.mediawiki.org/wiki/Extension:DublinCoreRdf and
	https://www.mediawiki.org/wiki/Extension:CreativeCommonsRdf as appropriate.
	* (bug 21107) Split error "customcssjsprotected" into separate messages for JS
	and CSS
	* Removed $wgCheckCopyrightUpload from DefaultSettings, since the relevant
	feature was removed in about 1.5.
	* LogPageValidTypes, LogPageLogName, LogPageLogHeader and LogPageActionText
	hooks have been removed.
	* New hook "Collation::factory" to allow extensions to create custom
	category collations.
	* $wgGroupPermissions now supports per namespace permissions.
	* $wgEnableAutoRotation enables or disables auto-rotation. Leaving it set to
	null will cause MediaWiki to determine if auto-rotation is available.

	=== New features in 1.18 ===
	* BREAKING CHANGE: action=watch / action=unwatch now requires a token.
	* BREAKING CHANGE: Article class hierarchy split into WikiPage (backend)
	and Article (frontend) hierarchies. Several hooks now pass a WikiPage object
	instead of an Article object. These hooks all use an $article parameter as
	documented in hooks.txt. Extensions should be updated to account for this,
	though most won't require any changes.
	* (bug 27860) Minor edit after clicking 'new section' tab
	Now the "This is a minor edit" checkbox is not available when you
	create a page or new section.
	* (bug 8130) Query pages should limit to content namespaces, not just main
	namespace.
	* Special:Contribs now redirects to Special:Contributions.
	* (bug 6672) Images are now autorotated according to their EXIF orientation.
	This only affects thumbnails; the source remains unrotated.
	* (bug 25708) Update case mappings and normalization to Unicode 6.0.0.
	* New hook ArticlePrepareTextForEdit added, called when preparing text to be
	saved.
	* New parser option PreSaveTransform added, allows the pre-save transformation
	to be selectively disabled.
	* Alternative to $wgHooks implemented, using the new Hooks class.
	* Add width parameter to Special:Filepath to allow getting the file path of a
	thumbnail.
	* (bug 26870) Add size to {{filepath:}}.
	* Upload warnings now show a thumbnail of the uploaded file.
	* Introduced the edittools-upload message, which will be inserted under the
	upload form instead of edittools if available.
	* (bug 26285) Extensions will be automatically generated on upload if the user
	specified a filename without extension.
	* (bug 26851) Special:UserRights now allows to prefill the reason field
	* New maintenance script to fix double redirects
	(maintenance/fixDoubleRedirects.php).
	* (bug 23315) New body classes to allow easier styling of special pages.
	* (bug 27159) Make email confirmation code expiration time configurable.
	* (bug 29047) CSS/JS for each user group is imported from
	MediaWiki:Group-sysop.js, MediaWiki:Group-autoconfirmed.css, etc.
	* (bug 24230) Uploads of ZIP types, such as MS Office or OpenOffice can now be
	safely enabled. A ZIP file reader was added which can scan a ZIP file for
	potentially dangerous Java applets. This allows applets to be blocked
	specifically, rather than all ZIP files being blocked.
	* (bug 2429) Allow selection of associated namespace in recent changes.
	* (bug 26217) File size is now checked before uploading in HTML5 browsers.
	* CSS stylesheet MediaWiki:Noscript.css is now loaded for users with JavaScript
	disabled (enclosed in the head in a <noscript> tag).
	* Added UserGetLanguageObject hook to change the language used in $wgLang.
	* (bug 14645) When $wgMiserMode is on, expensive special pages are styled
	differently (italicized by default) on Special:SpecialPages.

	several wikis.
	* When $wgAllowMicrodataAttributes is true, all itemtypes are allowed, not just
	the three that were defined in the original specification.
	* (bug 14706) Added support for the Imagick PHP extension.
	* (bug 18691) Added support for SVG rasterization using the Imagick PHP
	extension.
	* (bug 2581, bug 6834) Added links to thumbnail in several resolutions to the
	file description page. The sizes are set by $wgImageLimits.
	* (bug 28031) Add pageCount support to ArchivedFile.
	* (bug 27924) PhpHttpRequest doesn't return response body if HTTP != 200.
	* Added hook BitmapHandlerTransform to allow extension to transform a file
	without overriding the entire handler.
	* The parser now attempts to output markers for editsection tokens and defer the
	rendering of them post-cache to reduce parser cache fragmentation and ensure
	skin customizability of edit section links.
	* (bug 24755) AuthPlugin auto-creation of local accounts can now be aborted by
	other extensions by handling the 'AbortAutoAccount' hook, similar to the
	'AbortNewAccount' triggered by explicit account creations. (They are separate
	to avoid loops and confusion; auth plugins like CentralAuth need to handle
	AbortNewAccount separately.
	* Special:ListFiles is now transcludable.
	* (bug 13879) Special:Emailuser asks for suitable target user if called without.
	* (bug 16956) IPTC and XMP metadata now extracted from images.

	namespaces as articles.

	--include-files and can be imported using importDump.php --uploads;
	furthermore, it can import files from the filesystem using --image-base-path.
	* Three new hooks in Special:Undelete, 'UndeleteForm::showHistory',
	'UndeleteForm::showRevision' and 'UndeleteForm::undelete', so that extensions
	may override the usage of PageArchive class and replace it with their own
	class that extends PageArchive.
	* (bug 28915) Implement QUnit test suite for MediaWiki JavaScript.
	Also built-in support for distribution through a TestSwarm instance.

	* (bug 29397) Implement mw.Title module in core.
	* In MySQL 4.1.9+ with replication enabled, fetch the slave lag from SHOW SLAVE
	STATUS instead of SHOW PROCESSLIST. This ensures that lag is reported
	correctly in the case where there are no write events occurring. Note that
	the DB user now needs to have the REPLICATION CLIENT privilege if you are
	using replication.
	* Language codes in $wgDummyLanguageCodes are now excluded on localization
	statistics (maintenance/language/transstat.php).
	* (bug 29586) Make the (next 200) links on categories link directly to
	the relevant section of the category.
	* (bug 29109) Allow the automatic edit summary for redirect creation
	show the first bit of the new redirect page.
	* (bug 29723) mw.util.wikiGetlink() now defaults to wgPageName.
	* (bug 29680) Add GetDefaultSortkey hook to override the default sortkey.
	* (bug 16699) {{#language:}} accepts second parameter to specify the language in
	which the language name is wanted. Coverage depends on the cldr extension.

	* $wgAutopromoteOnce was added, allowing for users to be automatically promoted
	to explicit usergroups. If a group is removed from a user via
	Special:UserRights, it will not automatically be re-added. Configuration is
	similar to $wgAutopromote (see DefaultSettings.php).

	values for preferences a hook has been introduced in User:getDefaultOptions().
	Setting preferences in $wgDefaultUserOptions still work fine, but when reading
	them (i.e. with array_keys) to get a list of all preferences, then
	$wgDefaultUserOptions should no longer be used as it will contain those set
	via User:getDefaultOptions().

	to let styles easily hide or show things based on general JS availability.
	* (bug 31293) If Special:Userlogin is loaded over HTTPS, display

	== MediaWiki 1.17 ==

	== MediaWiki 1.17.5 ==
	2012-06-12

	This is a security release of the MediaWiki 1.17 branch.

	=== Summary of selected changes in 1.17 ===

	Selected changes since MediaWiki 1.16 that may be of interest:

	* A new installer has been introduced. It has a wizard-style interface which is
	translated into many languages. Many shortcomings in the old installer were
	addressed with this rewrite. Note that it is no longer required for the config
	directory to be made writable by the webserver. Instead the generated
	LocalSettings.php file is offered as a download, which you must then upload
	to the wiki's base directory.

	* ResourceLoader, a new framework for delivering client-side resources such as
	JavaScript and CSS, has been introduced. These resources are now delivered
	through the new entry point script "load.php", instead of as static files
	served directly by the web server. This allows minification, compression and
	client-side caching to be used more effectively, which should provide a net
	performance improvement for most users.

	* Category sorting has been improved.
	** Sorting is now case insensitive.
	** Sub-categories, pages and files can now be paged separately.
	** When several pages are given the same sort key, they sort by their
	names instead of randomly.

	* The lowest supported version of PHP is now 5.2.3. If necessary, please
	upgrade PHP prior to upgrading MediaWiki.

	=== Changes since 1.17.4 ===

	* (bug 36938) Correctly escape uselang attribute to prevent xss

	* (bug 35671) PHP Notice: Undefined index: gettoken in includes/api/ApiMain.php
	on line 598.

	=== Changes since 1.17.2 ===

	* (bug 22555) Remove or skip strip markers from tag hooks like <nowiki> in
	core parser functions which operate on strings, such as padleft.
	* (bug 34212) ApiBlock/ApiUnblock allow action to take place without a token
	parameter present.
	* (bug 34907) Fixed exposure of tokens through load.php that could have
	facilitated CSRF attacks.
	* (bug 35317) CSRF in Special:Upload.

	=== Changes since 1.17.1 ===
	* (bug 33117) prop=revisions allows deleted text to be exposed through cache
	pollution.
	* (bug 32709) Private Wiki users were always taken to Special:Badtitle on login.

	=== Changes since 1.17.0 ===

	* (bug 29726) Fixed failure to load internationalization messages in
	client-side scripts on WebKit-based browsers.

	into later transformations in the UI language.
	* (bug 29091) Fixed form of native name for Ossetic language (Иронау -> Ирон)

	work at all since 1.17 beta 1.

	multiple dots, was broken by the fix for bug 28840.
	* In the maintenance script purgeList.php, fixed a fatal error when a page
	title is given, instead of a URL.
	* (bug 19514) Unordered list list-style-image should be IE6-compatible (8-bit).
	* Installer checked for magic_quotes_runtime instead of register_globals.
	* $wgSVGMaxSize is now applied to the smaller of width or height, making very
	wide pano/timeline/diagram SVGs renderable at saner sizes.
	* (bug 29959) Installer fatal when cURL and allow_url_fopen is disabled and user
	tries to subscribe to mediawiki-announce.
	* Installer checked for magic_quotes_runtime instead of register_globals
	* (bug 30131) XCache with variable caching disabled no longer used for variable
	caching (CACHE_ACCEL)
	* (bug 30264) Changed installer-generated LocalSettings.php to use
	require_once() instead require() for included extensions.
	* (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP
	warnings/notices to be thrown

	updater for Oracle DB.
	* (bug 32276) Skins were generating output using the internal page title which
	would allow anonymous users to determine whether a page exists, potentially
	leaking private data. In fact, the curid and oldid request parameters would
	allow page titles to be enumerated even when they are not guessable.
	* (bug 32616) action=ajax requests were dispatched to the relevant internal
	functions without any read permission checks being done. This could lead to
	data leakage on private wikis.

	* Fixed syntax error in generated LocalSettings.php when a non-default user
	rights profile is chosen.
	* (bug 29399) Fixed PostgreSQL installation when the DB user for installation
	is the same as the one for web access.
	* (bug 29233) Fixed failover for DB slave servers. When a DB slave went down,
	an error was immediately shown to the user, instead of trying another slave.
	Was broken since 1.17 beta 1.
	* (bug 29278) Fixed PHP fatal error when attempting to add text to a page via a
	redirect.
	* (bug 29408) Fixed uploads of files with MIME types that aren't detected by
	MediaWiki.
	* Removed DEFAULT '' NOT NULL field definitions from Oracle DB schema because
	using the DEFAULT value ('') in DML broke Oracle backend as it treats an
	empty VARCHAR2 value as NULL. Indexes on Oracle do not require NOT NULL
	fields.

	=== Changes since 1.17 beta 1 ===

	* Fixed warning about missing file "password.js".
	* When installing on MySQL, don't attempt to create a new database user if the
	same user is used for installation and web access.
	* Fixed SQL query errors in queries with table aliases.
	* (bug 27891) Fixed the "chronology protector", broken since 1.17beta1, which
	ensures that when database replication is used, the new version is seen by
	the user immediately after they create or edit an article.
	* (bug 28845) Allow PostgreSQL installation using a non-root user account which
	has role creation abilities.
	* When installing on PostgreSQL and the install account is the same as the web
	account, check to make sure that the account has suitable privileges in the
	mediawiki schema.
	* (bug 28172) Fixed error in PostgreSQL installation when creating the wiki
	sysop account.
	* Fixed an issue with the Oracle installer in cases where the user is different
	to the database name.
	* Added "unblockself" to the list of available rights.
	* In the installer, fixed the "user rights profile" option, it never worked.
	* (bug 29117) Fixed Hebrew localisation of the installer.
	* (bug 28840) Reduce the collateral damage caused by the fix for bug 28235 (XSS
	on Internet Explorer 6 due to a file extension in the query string) by
	reducing the number of URLs that are blocked, and by redirecting the request
	to a safer URL where possible instead of blocking it.
	* (bug 28812) Fixed documentation of API action=parse.
	* (bug 28979) Fixed styling of <abbr> and <acronym>.
	* Fixed the error message displayed when you try to create an account by email,
	but an email address is not given.
	* Fixed JS error due to missing dependency for jquery.suggestions.
	* Exposed $wgExtensionAssetsPath in JavaScript.
	* (bug 28738) Made ResourceLoader support environments with small URL length
	limits. The length limit can be configured via
	$wgResourceLoaderMaxQueryLength, and this is set automatically in the
	generated LocalSettings.php when the php.ini variable
	"suhosin.get.max_value_length" is set. When a URL exceeds this limit, the
	request is split up. Also, reduced the average length of load.php URLs by
	using a more compact parameter format.
	* (bug 25262) Fix for minification of hardcoded data: URIs in CSS.
	* (bug 25124) Respect $wgStyleDirectory in ResourceLoader.
	* Allow installation when no HTTP client is available, don't throw an exception.
	* (bug 27465) Fix metadata extraction for SVG files using unusual namespace
	names.

	PHP memory limit should work again.
	* Fixed the display of comments in the new user log.
	* (bug 28237) When installing extensions using the web-based installer, create
	any necessary database tables.
	* (bug 28983) Fixed automated installation of extensions that overwrite $path.
	* Fixed error caused by missing magic words.
	* Fixed breakage of article editing in PostgreSQL due to text search
	configuration errors.
	* Fixed the HTTPS client used when Curl is not available. This avoids an error
	during install about failure of the mediawiki-announce subscription.
	* (bug 28162) When installing to PostgreSQL, respect the "database port" input,
	it was ignored.

	=== Configuration changes in 1.17 ===

	* $wgLogAutocreatedAccounts controls whether autocreation of accounts is logged
	to new users log.
	* (bug 22858) $wgLocalStylePath is by default set to the same value as
	$wgStylePath but should never point to a different domain than the site is
	on, allowing skins to use .htc files which are not cross-domain friendly.
	* $wgFileStore has been deprecated. The only usage $wgFileStore['deleted'] has
	been turned into $wgDeletedDirectory.
	* $wgDeletedDirectory has been added to specify what directory to place deleted
	uploads in.
	* IBM DB2 database no longer uses the db specific $wgDBport_db2 variable but the
	normal $wgDBport.

	$wgUseMemCached, $wgDisableSearchContext, $wgColorErrors, $wgUseZhdaemon,
	$wgZhdaemonHost and $wgZhdaemonPort.
	* (bug 24408) The include_path is not modified in the default LocalSettings.php
	* $wgVectorExtraStyles was removed, and is no longer in use.
	* Removed $wgUpdates for database updates; extensions should use
	DatabaseUpdater::addExtensionUpdate() via the LoadExtensionSchemaUpdates hook.
	* Removed $wgServerName. It doesn't need to be set anymore and is no longer
	available as input for other configuration items, either.
	* It's no longer necessary for LocalSettings.php to include DefaultSettings.php.
	* It's no longer necessary to set $wgCacheEpoch to the file modification time
	of LocalSettings.php, in LocalSettings.php itself. Instead, this is done
	automatically if $wgInvalidateCacheOnLocalSettingsChange is true (which is
	the default).
	* $wgCopyrightIcon is deprecated and $wgFooterIcons['copyright']['copyright']
	should be used instead.
	* $wgSysopUserBans is deprecated, and will be made permanently true in 1.18.
	If you need this functionality, you should use the BlockIp hook to filter and
	reject such blocks.
	* $wgSysopRangeBans is deprecated, you should set $wgBlockCIDRLimit to maximum
	(32 for IPv4, 128 for IPv6), equivalent to allowing rangeblocks of only 1
	address at a time.

	* $wgAllowRealName and $wgAllowUserSkin were deprecated in favor of
	$wgHiddenPrefs[] = 'realname', but the former are still retained

	* (bug 9257) $wgRCMaxAge now defaults to three months
	* $wgDevelopmentWarnings can be set to true to show warnings about deprecated
	functions and other potential errors when developing.
	* Subpages are now enabled in the MediaWiki namespace by default. This is
	mainly a cosmetic change, and does not in any way affect the MessageCache,
	which was already effectively treating the namespace as if it had subpages.
	* Oracle: maintenance/ora/user.sql script for creating DB user on oracle with
	appropriate privileges. Creating this user with web-install page requires
	oci8.privileged_connect set to On in php.ini.
	* Removed UserrightsChangeableGroups hook introduced in 1.14
	* Added $wgCacheDirectory, to replace $wgFileCacheDirectory,
	$wgLocalMessageCache, and any other local caches which need a place to put
	files.
	* $wgFileCacheDirectory is no longer set to anything by default, and so either
	needs to be set explicitly, or $wgCacheDirectory needs to be set instead.
	* $wgLocalMessageCache has been removed. Instead, set $wgUseLocalMessageCache
	to true
	* Removed $wgEnableSerializedMessages and $wgCheckSerialized. Similar
	functionality is now available via $wgLocalisationCacheConf.
	* $wgMessageCache->addMessages() is deprecated. Messages added via this

	* $wgMaintenanceScripts for extensions to add their scripts to the default list
	* $wgMemoryLimit has been added, default value '50M'

	characters in file names.

	* $wgEnableSorbs renamed to $wgDnsBlacklistUrls ($wgEnableSorbs kept for
	backward compatibility)
	* $wgUploadNavigationUrl now also affects inline images that do not
	exist. In that case the URL will get (?\|&)wpDestFile=<filename> appended to
	it as appropriate.
	* If $wgLocaltimezone is null, use the server's timezone as the default for
	signatures. This was always the behavior documented in DefaultSettings.php
	but has not been the actual behavior for some time: instead, UTC was used
	by default.
	* Added $wgExtensionAssetsPath, to decouple assets serving from $wgScriptPath.
	If not specified it will default to $wgScriptPath/extensions
	* Added $wgCountTotalSearchHits to make search UI display total number of hits
	with some search engines.
	* Added $wgAdvertisedFeedTypes to decide what feed types (RSS, Atom, both, or
	neither) MediaWiki advertises. Default is array( 'atom' ), so RSS is no
	longer advertised by default (but it still works).
	* Added $wgMemCachedTimeout, controls how long to wait for data from the
	memcached servers.
	* New configuration variables $wgDebugTimestamps and $wgDebugPrintHttpHeaders
	for controlling debug output.

	have these rights stripped from them.
	* Added a PHP port of CDB (constant database), for improved local caching when
	the DBA extension is not available.
	* Introduced a new system for localisation caching. The system is based around
	fast fetches of individual messages, minimising memory overhead and startup
	time in the typical case. The database backend will be used by default, but
	set $wgCacheDirectory to get a faster CDB-based implementation.
	* Expanded the number of variables which can be set in the extension messages
	files.
	* Added a feature to allow per-article process pool size control for the parsing

	* If config/ directory is not executable, the command to make it executable
	now asks the user to cd to the correct directory
	* Add experimental new external authentication framework, ExternalAuth
	* (bug 18768) Remove AdminSettings requirements. Maintenance environment
	will still load it if it exists, but it's not required for anything

	* wgMainPageTitle variable now available to JavaScript code to identify the main
	page link, so it doesn't have to be extracted from the link URLs.
	* (bug 16836) Display preview of signature in user preferences and describe its
	use
	* The default output format is now HTML 5 instead of XHTML 1.0 Transitional.
	This can be disabled by setting $wgHtml5 = false;. Specific features enabled
	if HTML 5 is used:
	** Some extra inputs will be autofocused, in supporting browsers.
	** The summary attribute has been removed from tables of contents. summary is
	obsolete in HTML 5 and wasn't useful here anyway.

	=== Changes since 1.14.0 ===

	* (bug 17737) Fixed russian URLs for Special:BookSources

	the pagelinks table
	* (bug 17897) Fixed string offset error in <pre> tags
	* (bug 17832) Fixed action=delete returning 'unknownerror' instead of
	'permissiondenied' when the user is blocked
	* Fixed performance regression when accessing deleted (archived) files
	* (bug 19693) Fixed cross-site scripting vulnerability in Special:Block

	== MediaWiki 1.14.0 ==
	=== Changes since 1.14.0rc1 ===

	* Fixed the performance of the backlinks API module
	* (bug 17420) Send the correct content type from action=raw when the HTML file
	cache is enabled.
	* (bug 17437) Fixed incorrect link to web-based installer
	* (bug 17527) Fixed missing MySQL-specific options in installer

	=== Configuration changes in 1.14 ===

	* $wgExemptFromUserRobotsControl is an array of namespaces to be exempt from
	the effect of the new __INDEX__/__NOINDEX__ magic words. (Default: null, ex-
	empt all content namespaces.)
	* $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4
	has been $wgSearchForwardUrl.
	* (bug 15080) $wgOverrideSiteFeed has been added. Setting either
	$wgSiteFeed['rss'] or 'atom' to a URL will override the default Recent
	Changes feed that appears on all pages.
	* $wgSQLiteDataDirMode has been introduced as the default directory mode for
	SQLite data directories on creation. Note that this setting is separate from
	$wgDirectoryMode, which applies to all normal dirs created by MediaWiki.
	* $wgGroupsAddToSelf and $wgGroupsRemoveFromSelf now work more like
	$wgAddGroups and $wgRemoveGroups, where the user must belong to a specified
	group in order to add or remove those groups from themselves.
	Backwards compatibility is maintained.
	* $wgRestrictDisplayTitle controls if the use of the {{DISPLAYTITLE}} magic
	word is restricted to titles equivalent to the actual page title. This
	is true by default, but can be set to false to allow any title.
	* $wgSpamRegex may now be an array of multiple regular expressions.
	* $wgAjaxSearch has been removed; use $wgEnableMWSuggest instead.
	* Editing the MediaWiki namespace is now unconditionally restricted to people
	with the editinterface right, configuring this in $wgNamespaceProtection
	is not required.
	* $wgAllowExternalImagesFrom may now be an array of multiple strings.
	* Introduced $wgEnableImageWhitelist to toggle the on-wiki external image
	whitelist on or off.
	* Added $wgRenderHashAppend to append some string to the parser cache and the
	sitenotice cache keys.
	* $wgRCChangedSizeThreshold is now a positive integer by default,
	* (bug 16006) $wgEnableWriteAPI is now true by default. Authorized can perform
	write actions using the API.
	* Added $wgRC2UDPInterwikiPrefix which adds an interwiki prefix
	($wgLocalInterwiki) onto the page names in the UDP feed.
	* Added $wgAllowUserSkin to let the wiki's owner disable user selectable skins
	on the wiki. If it's set to false, then the skin used will always be
	$wgDefaultSkin.
	* Added $wgEnotifUseRealName, which allows UserMailer to send out e-mails based
	on the user's real name if one is set. Defaults to false (use the username)
	* Removed the 'apiThumbCacheDir' option from $wgForeignFileRepos (only used in
	ForeignAPIRepo)
	* (bug 44) Image namespace and accompanying talk namespace renamed to File.
	For backward compatibility purposes, Image still works. External tools may
	need to be updated.
	* The constants NS_FILE and NS_FILE_TALK can now be used instead of NS_IMAGE and
	NS_IMAGE_TALK. The old constants are retained as aliases for compatibility,
	and should still be used in code meant to be compatible with v1.13 or older.
	* MediaWiki can be forced to use private IPs forwarded by a proxy server by
	using $wgUsePrivateIPs.
	* The 'BeforeWatchlist' hook has been removed due to internal changes in
	Special:Watchlist. 'SpecialWatchlistQuery' should now be used by extensions
	to customize the watchlist database query.

	=== Migrated extensions ===
	The following extensions are migrated into MediaWiki 1.14:

	* Special:DeletedContributions to show deleted user contributions (was
	extension DeletedContributions)
	* Special:Log/newusers recording new users (was extension Newuserlog)
	* Special:LinkSearch to search for external links (was extension LinkSearch)
	* RenderHash
	* NoMoveUserPages
	* UniversalEditButton

	=== New features in 1.14 ===

	* New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
	'Special:ListUsers/GROUP/USER', in addition to the older syntax
	'Special:ListUsers/GROUP' where GROUP is a valid group name.
	* Configurable per-namespace and per-page notices for the edit form,
	respectively MediaWiki:Editnotice-# where # is the namespace number, and
	MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
	PAGENAME is the page name minus the namespace prefix.
	* (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
	search engine indexing on a per-article basis.
	* Handheld stylesheet options
	* Added 'DoEditSectionLink' hook as a cleaner unified version of the old
	'EditSectionLink' and 'EditSectionLinkForOther' hooks. Note that the
	'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
	run in all cases instead, so extensions using the old hooks should still work
	if they ran roughly the same code for both hooks (as is almost certain).
	* Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
	$wgCleanSignatures=false
	* Extensions can use the SkinBuildSidebar hook to modify the content of the
	sidebar and add custom portlets to it

	ables into the output of Skin::makeVariablesScript

	Special:ListGroupRights

	being converted or not

	Patch by Emufarmers
	* Unescape more "safe" characters when producing URLs, for added prettiness

	after the page content and article metadata. Updated all skins and skin
	templates to work with that hook.

	'ignore-groups'. Patch by Louperivois

	* (bug 15422) Sort more different types of numbers in sortable tables

	maxlag check fails, just like index.php does
	* Added "link" parameter to image links, to allow images to link to an
	arbitrary title or URL. This should replace inaccessible and incomplete
	solutions such as CSS-based overlays and ImageMap.
	* (bug 368) Don't use caption for alt attribute; allow manual specification
	using new "alt=" parameter for images
	* (bug 44) The {{ns:}} core parser function now also accepts localized
	namespace names and aliases; also, its output now uses spaces instead of
	underscores to match the behavior of the {{NAMESPACE}} magic word
	* Added the ability to display user edit counts in Special:ListUsers. Off by
	default, enabled with $wgEdititis = true (named after the medical condition
	marked by unhealthy obsession with edit counts).
	* Added a file cache to the parser to improve page rendering time on pages with
	several uses of the same image.
	* (bug 1250) Users can still use "show preview" and "show changes" even if the

	can now support 1.2 as well as 1.3 (gfdl1_3).

	against exposure of deleted files with known SHA-1 hashes on default
	installations.

	handling, can lead to annoying behavior such as text rendering backwards
	* Fixed minor bug where the memcached value for how many accounts an IP had
	created that day would be increased even if $wgAccountCreationThrottle was
	hit. This meant if an IP hit the throttle and then the throttle was raised
	later that day, the IP still couldn't create another account, because it
	had marked them as having created another account, when their last account
	creation had actually failed.

	* (bug 16850) $wgActionPaths can have query strings now, previously, this broke
	local URLs

	== MediaWiki 1.13 ==

	== MediaWiki 1.13.5 ==

	February 22, 2009

	This is a maintenance update to the Summer 2008 snapshot release of MediaWiki.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept
	"ready to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature developments
	will be made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain
	it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

	== Changes since 1.13.4 ==

	* (bug 17449) Fixed PostgreSQL installation
	* (bug 17527) Fixed missing MySQL-specific options in installer

	== Changes since 1.13.3 ==

	A number of cross-site scripting (XSS) security vulnerabilities were discovered
	in the web-based installer (config/index.php). These vulnerabilities all
	require a live installer -- once the installer has been used to install a wiki,
	it is deactivated.

	Note that cross-site scripting vulnerabilities can be used to attack any website
	in the same cookie domain. So if you have an uninstalled copy of MediaWiki on
	the same site as an active web service, MediaWiki could be used to attack the
	active service.

	If you are hosting an old copy of MediaWiki that you have never installed, you
	are advised to remove it from the web.

	== Changes since 1.13.2 ==

	David Remahl of Apple's Product Security team has identified a number of
	security issues in previous releases of MediaWiki. Subsequent analysis by the
	MediaWiki development team expanded the scope of these vulnerabilities. The
	issues with a significant impact are as follows:

	* An XSS vulnerability affecting all MediaWiki installations between 1.13.0 and
	1.13.2. [CVE-2008-5249]
	* A local script injection vulnerability affecting Internet Explorer clients for
	all MediaWiki installations with uploads enabled. [CVE-2008-5250]
	* A local script injection vulnerability affecting clients with SVG scripting
	capability (such as Firefox 1.5+), for all MediaWiki installations with SVG
	uploads enabled. [CVE-2008-5250]
	* A CSRF vulnerability affecting the Special:Import feature, for all MediaWiki
	installations since the feature was introduced in 1.3.0. [CVE-2008-5252]

	XSS (cross-site scripting) vulnerabilities allow an attacker to steal an
	authorised user's login session, and to act as that user on the wiki. The
	authorised user must visit a web page controlled by the attacker in order to
	activate the attack. Intranet wikis are vulnerable if the attacker can
	determine the intranet URL.

	Local script injection vulnerabilities are like XSS vulnerabilities, except
	that the attacker must have an account on the local wiki, and there is no
	external site involved. The attacker uploads a script to the wiki, which another
	user is tricked into executing, with the effect that the attacker is able to act
	as the privileged user.

	CSRF vulnerabilities allow an attacker to act as an authorised user on the wiki,
	but unlike an XSS vulnerability, the attacker can only act as the user in a
	specific and restricted way. The present CSRF vulnerability allows pages to be
	edited, with forged revision histories. Like an XSS vulnerability, the
	authorised user must visit the malicious web page to activate the attack.

	These four vulnerabilities are all fixed in this release.

	David Remahl also reminded us of some security-related configuration issues:

	* By default, MediaWiki stores a backup of deleted images in the images/deleted
	directory. If you do not want these images to be publically accessible, make
	sure this directory is not accessible from the web. MediaWiki takes some steps
	to avoid leaking these images, but these measures are not perfect.
	* Set display_errors=off in your php.ini to avoid path disclosure via PHP fatal
	errors. This is the default on most shared web hosts.
	* Enabling MediaWiki's debugging features, such as $wgShowExceptionDetails, may
	lead to path disclosure.

	Other changes in this release:

	* Avoid fatal error in profileinfo.php when not configured.
	* Add a .htaccess to deleted images directory for additional protection against
	exposure of deleted files with known SHA-1 hashes on default installations.
	* Avoid streaming uploaded files to the user via index.php. This allows
	security-conscious users to serve uploaded files via a different domain, and
	thus client-side scripts executed from that domain cannot access the login
	cookies. Affects Special:Undelete, img_auth.php and thumb.php.
	* When streaming files via index.php, use the MIME type detected from the
	file extension, not from the data. This reduces the XSS attack surface.
	* Blacklist redirects via Special:Filepath. Such redirects exacerbate any
	XSS vulnerabilities involving uploads of files containing scripts.
	* Internationalisation updates.

	== Changes since 1.13.1 ==

	* Security: Work around misconfiguration by requiring strict comparisons for
	in_array in User::isAllowed().
	* (bug 14944) Added $wgShellLocale for configuration of an appropriate locale
	to use for LC_CTYPE during shell invocation. For servers that don't have
	en_US.utf8. Also added locale detection during install.
	* Localisation updates
	* Security: Fixed XSS vulnerability in useskin parameter.

	== Changes since 1.13.0 ==

	* (bug 15460) Fixed intermittent deadlock errors and poor concurrent
	performance for installations without memcached.
	* (bug 13770) Fixed DOM module detection for installations with both dom
	and domxml.
	* (bug 15148) Fixed Special:BlockIP for PostgreSQL
	* Fixed SQLite support for non-memcached installations
	* Localisation updates, Achinese (ace) added.

	== Changes since 1.13.0rc2 ==

	* (bug 13770) Fixed incorrect detection of PHP's DOM module
	* Fix regression from r37834: accesskey tooltip hint should be given for the
	minor edit and watch labels on the edit page.
	* Updated Chinese simplified/traditional conversion tables

	== Changes since 1.13.0rc1 ==

	* $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4
	has been $wgSearchForwardUrl.
	* (bug 14907) DatabasePostgres::fieldType now defined.
	* (bug 14966) Fix SearchEngineDummy class for silently non-functional search
	on Sqlite instead of horribly fatal error breaky one.
	* (bug 14987) Only fix double redirects on page move when the checkbox is
	checked
	* (bug 13376) Use $wgPasswordSender, not $wgEmergencyContact, as return
	address for page update notification mails.
	* API: Registration time of users registered before the DB field was created is
	now shown as empty instead of the current time.
	* (bug 14904): fragments were lost when redirects were fixed.
	* Added magic word __STATICREDIRECT__ to suppress the redirect fixer
	* (bug 15035) Revert English linkTrail to /^([a-z]+)(.*)$/sD, as it was before
	r36253. Multiple reports of breakage due to old (pre-5.0) PCRE libraries,
	both bundled with PHP and packaged with distros such as RHEL.
	* (bug 14944) Shell invocation of external programs such as ImageMagick convert
	was broken in PHP 5.2.6, if the server had a non-UTF-8 locale.


	=== Configuration changes in 1.13 ===

	* New option $wgFeed can be set false to turn off syndication feeds
	* (bug 5745) Special:Whatlinkshere now shows up to $wgMaxRedirectLinksRetrieved

	share.
	* Automatic edit summaries can be disabled with $wgUseAutomaticEditSummaries

	* $wgActiveUserDays is that number of days
	* $wgRateLimitsExcludedGroups has been deprecated in favor of
	$wgGroupPermissions[]['noratelimit']. The former still works, however.

	* New $wgRC2UDPOmitBots allows user to omit bot edits from UDP output.
	Default: false
	* Removed $wgEnableCascadingProtection option. Disabling cascading protection
	is no longer possible.
	* $wgMessageCacheType defines now the type of cache used by the MessageCache
	class, previously it was choosen based on $wgParserCacheType
	* $wgExtensionAliasesFiles option to simplify adding aliases to special pages
	provided by extensions, in a similar way to $wgExtensionMessagesFiles
	* Added $wgXMLMimeTypes, an array of XML mimetypes we can check for
	with MimeMagic.
	* Added $wgDirectoryMode, which allows for setting the default CHMOD value when
	creating new directories.
	* (bug 14843) $wgCookiePrefix can be set by LocalSettings now, false defaults
	current behavior.

	=== New features in 1.13 ===

	* __HIDDENCAT__ on a category page causes the category to be hidden on the
	article page
	* Do not show edit permissions errors on a red link click, just redirect to the

	* Add a new hook ImageBeforeProduceHTML to allow extensions to modify wikitext
	image syntax output

	== MediaWiki 1.12 ==

	== MediaWiki 1.12.4 ==

	February 7, 2009

	A number of cross-site scripting (XSS) security vulnerabilities were discovered
	in the web-based installer (config/index.php). These vulnerabilities all
	require a live installer -- once the installer has been used to install a wiki,
	it is deactivated.

	Note that cross-site scripting vulnerabilities can be used to attack any
	website in the same cookie domain. So if you have an uninstalled copy of
	MediaWiki on the same site as an active web service, MediaWiki could be used to
	attack the active service.

	If you are hosting an old copy of MediaWiki that you have never installed, you
	are advised to remove it from the web.

	== MediaWiki 1.12.3 ==

	* Fixed packaging/distribution error. Many files were missing from the
	distributed tarball.

	== MediaWiki 1.12.2 ==

	David Remahl of Apple's Product Security team has identified a number of
	security issues in previous releases of MediaWiki. Subsequent analysis by the
	MediaWiki development team expanded the scope of these vulnerabilities. The
	issues with a significant impact are as follows:

	* A local script injection vulnerability affecting Internet Explorer clients
	for all MediaWiki installations with uploads enabled. [CVE-2008-5250]
	* A local script injection vulnerability affecting clients with SVG scripting
	capability (such as Firefox 1.5+), for all MediaWiki installations with SVG
	uploads enabled. [CVE-2008-5250]
	* A CSRF vulnerability affecting the Special:Import feature, for all MediaWiki
	installations since the feature was introduced in 1.3.0. [CVE-2008-5252]

	A local script injection vulnerability allows an attacker with a wiki account
	to steal another user's login session, and to act as that user on the wiki. The
	attacker uploads a malicious script file, and tricks the victim into executing
	it.

	CSRF vulnerabilities allow an attacker to act as an authorised user on the
	wiki, but unlike an XSS vulnerability, the attacker can only act as the user in
	a specific and restricted way. The present CSRF vulnerability allows pages to
	be edited, with forged revision histories. Like an XSS vulnerability, the
	authorised user must visit the malicious web page to activate the attack.

	These three vulnerabilities are all fixed in this release.

	David Remahl also reminded us of some security-related configuration issues:

	* By default, MediaWiki stores a backup of deleted images in the images/deleted
	directory. If you do not want these images to be publically accessible, make
	sure this directory is not accessible from the web. MediaWiki takes some steps
	to avoid leaking these images, but these measures are not perfect.
	* Set display_errors=off in your php.ini to avoid path disclosure via PHP fatal
	errors. This is the default on most shared web hosts.
	* Enabling MediaWiki's debugging features, such as $wgShowExceptionDetails, may
	lead to path disclosure.

	Other changes in this release:

	* Avoid fatal error in profileinfo.php when not configured.
	* Add a .htaccess to deleted images directory for additional protection against
	exposure of deleted files with known SHA-1 hashes on default installations.
	* Avoid streaming uploaded files to the user via index.php. This allows
	security-conscious users to serve uploaded files via a different domain, and
	thus client-side scripts executed from that domain cannot access the login
	cookies. Affects Special:Undelete, img_auth.php and thumb.php.
	* When streaming files via index.php, use the MIME type detected from the file
	extension, not from the data. This reduces the XSS attack surface.
	* Blacklist redirects via Special:Filepath. Such redirects exacerbate any XSS
	vulnerabilities involving uploads of files containing scripts.
	* Internationalisation updates.

	== MediaWiki 1.12.1 ==

	Changes since 1.12.0:
	* (bug [[bugzilla:13522\|13522]]) Fix fatal error in Parser::extractTagsAndParams

	wfTimestamp()
	* (bug [[bugzilla:13770\|13770]]) Use Preprocessor_Hash by default to avoid
	missing DOM module errors

	prop=extlinks are now handled properly.
	* (bug [[bugzilla:13482\|13482]]) API: Disabled search types handled properly

	* Security: Work around misconfiguration by requiring strict comparisons for
	in_array in User::isAllowed().
	* Security: Fixed XSS vulnerability in useskin parameter.

	== MediaWiki 1.12.0 ==

	This is the quarterly branch release of [[MediaWiki]] for Winter 2008.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept "ready
	to run", and in fact runs our own sites on [[wikipedia:\|Wikipedia]].

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature developments will be
	made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain it
	from source control: [[Download from SVN]].

	Changes since 1.12.0rc1:
	*(bug [[bugzilla:13359\|13359]]) Double-escaping in [[Special:Allpages]].
	*Localization updates.

	=== Configuration changes in 1.12 ===
	* Marking edits as bot edits with Special:Contributions?bot=1 now requires the
	markbotedit permission, rather than the rollback permission previously used.
	This permission is assigned by default to the sysop group.
	* MediaWiki now checks if serialized files are out of date. New configuration
	variable $wgCheckSerialized can be set to false to enable old behavior (i.e.
	to not check and assume they are always up to date)
	* The rollback permission can now be rate-limited using the normal mechanism.
	* New configuration variable $wgExtraLanguageNames
	* Behavior of $wgAddGroups and $wgRemoveGroups changed. New behavior:
	* * Granting the userrights privilege allows arbitrary changing of rights.
	* * Without the userrights privilege, a user will be able to add and/or
	remove the groups specified in $wgAddGroups and $wgRemoveGroups for
	any groups they are in.
	* New permission userrights-interwiki for changing user rights on foreign wikis.
	* $wgImplicitGroups for groups that are hidden from Special:Listusers, etc.
	* $wgAutopromote: automatically promote users who match specified criteria
	* $wgGroupsAddToSelf, $wgGroupsRemoveFromSelf: allow users to add or remove
	themselves from specified groups via Special:Userrights.
	* When $wgUseTidy has been enabled, PHP's Tidy module is now used if it is
	present, in preference to an external Tidy executable which may or may not
	be present. To force use of external Tidy even when the PHP module is
	available, set $wgTidyInternal to false.


	=== New features in 1.12 ===
	* (bug 10735) Add a warning for non-descriptive filenames at Special:Upload
	* Add {{filepath:}} parser function to get full path to an uploaded file,
	complementing {{fullurl:}} for pages.

	click it. Existing clear links will fall back to the raw editor, which is
	very easy to clear your watchlist with.
	* (bug 1405) Add wgUseNPPatrol option to control patroling for new articles
	on Special:Newpages
	* LogLine hook added to allow formatting custom entries in Special:Log.

	editing to allow CSS styling.
	* Parser now returns list of sections
	* When a user is prohibited from creating a page, a title of "View source"
	makes no sense, and there should be no "Return to [[Page]]" link.
	* (bug 12486) Protected titles now give a warning for privileged editors.
	* (bug 9939) Special:Search now sets focus to search input box when no existing
	search is active

	for Special:Userlogin?type=signup
	* (bug 12214) Add a predefined list of delete reasons to the file deletion form
	* Merged backends for OpenSearch suggestions and AJAX search.
	Both now accept namespace prefixes, handle 'Media:' and 'Special:' pages,
	and reject interwiki prefixes. PrefixSearch class centralizes this code,
	and the backend part can be overridden by the PrefixSearchBackend hook.
	* (bug 10365) Localization of Special:Version
	* When installing using Postgres, the Pl/Pgsql language is now checked for
	and installed when at the superuser level.

	== Parser changes in 1.12 ==

	For help with migration to the MediaWiki 1.12 parser, please visit:

	http://meta.wikimedia.org/wiki/Migration_to_the_new_preprocessor

	The parser pass order has changed from

	* Extension tag strip and render
	* HTML normalisation and security
	* Template expansion
	* Main section...

	to

	* Template and extension tag parse to intermediate representation
	* Template expansion and extension rendering
	* HTML normalisation and security
	* Main section...

	The main effect of this for the user is that the rules for uncovered syntax
	have changed.

	Uncovered main-pass syntax, such as HTML tags, are now generally valid, whereas
	previously in some cases they were escaped. For example, you could have "<ta" in
	one template, and "ble>" in another template, and put them together to make a
	valid <table> tag. Previously the result would have been "<table>".

	Uncovered preprocessor syntax is generally not recognised. For example, if you
	have "{{a" in Template:A and "b}}" in Template:B, then "{{a}}{{b}}" will be
	converted to a literal "{{ab}}" rather than the contents of Template:Ab. This
	was the case previously in HTML output mode, and is now uniformly the case in
	the other modes as well. HTML-style comments uncovered by template expansion
	will not be recognised by the preprocessor and hence will not prevent template
	expansion within them, but they will be stripped by the following HTML security
	pass.

	Bug 5678 has been fixed. This has a number of user-visible effects related to
	the removal of this double-parse. Please see the wiki page for examples.

	Message transformation mode has been removed, and replaced with "preprocess"
	mode. This means that some MediaWiki namespace messages may need to be updated,
	especially ones which took advantage of the terribly counterintuitive behavior
	of the former message mode.

	The header identification routines for section edit and for numbering section
	edit links have been merged. This removes a significant failure mode and fixes a
	whole category of bugs (tracked by bug #4899). Wikitext headings uncovered by
	template expansion will still be rendered into a heading tag, and will get an
	entry in the TOC, but will not have a section edit link. HTML-style headings
	will also not have a section edit link. Valid wikitext headings present in the
	template source text will get a template section edit link. This is a major
	break from previous behavior, but I believe the effects are almost entirely
	beneficial.

	The main motivation for making these changes was performance. The new two-pass
	preprocessor can skip "dead branches" in template expansion, such as unfollowed
	#switch cases and unused defaults for template arguments. This provides a
	significant performance improvement in template-heavy test cases taken from
	Wikipedia. Parser function hooks can participate in this performance improvement
	by using the new SFH_OBJECT_ARGS flag during registration.

	The pre-expand include size limit has been removed, since there's no efficient
	way to calculate such a figure, and it would now be meaningless for performance
	anyway. The "preprocessor node count" takes its place, with a generous default
	limit.

	The context in which XML-style extension tags are called has changed, so
	extensions which make use of the parser state may need compatibility changes.

	The new preprocessor syntax has been documented in Backus-Naur Form at:

	https://www.mediawiki.org/wiki/Preprocessor_ABNF

	The ExpandTemplates extension now has the ability to generate an XML parse
	tree from wikitext source. This parse tree corresponds closely to the grammar
	documented on that page.

	=== API changes in 1.12 ===

	== MediaWiki 1.11 ==

	== MediaWiki 1.11.2 ==

	March 2, 2008

	This is a security release of the Fall 2007 snapshot release of MediaWiki.
	Possible cross-site information leaks using the callback parameter for
	JSON-formatted results in the API are prevented by dropping user credentials.

	MediaWiki release versions prior to 1.11 are not vulnerable, as they do not
	include the callback feature which allows client-side JavaScript on other sites
	to reach API data.

	Changes in this release:

	* User credentials are dropped for API JSON requests using a callback
	* Edit tokens are not reported for API JSON requests using a callback

	== MediaWiki 1.11.1 ==

	January 23, 2008

	This is a security and bugfix release of the Fall 2007 snapshot release of
	MediaWiki. A potential XSS injection vector affecting api.php only for
	Microsoft Internet Explorer users has been closed.

	Changes in this release:
	* (bug [[bugzilla:11450\|11450]]) Fix creation of objectcache table on upgrade
	* (bug [[bugzilla:11462\|11462]]) Fix typo in LanguageGetSpecialPageAliases hook
	name
	* Fix regression in LinkBatch.php breaking PHP 5.0
	* Security fix for API on MSIE

	To work around the vulnerability without upgrading, you may disable the API if
	you don't need it:
	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	Not vulnerable versions:
	* 1.12 or later
	* 1.11 >= 1.11.1
	* 1.10 >= 1.10.3
	* 1.9 >= 1.9.5
	* 1.8 any version (if $wgEnableAPI has been left off)

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.2
	* 1.9 <= 1.9.4
	* 1.8 any version (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the API
	functionality, however the BotQuery extension is similarly vulnerable unless
	updated to the latest SVN version.

	== MediaWiki 1.11.0 ==

	September 10, 2007

	This is the Fall 2007 snapshot release of MediaWiki.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept "ready
	to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature developments will be
	made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain it
	from source control: [[Download from SVN]]

	This is the Summer 2007 branch release of MediaWiki.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept
	"ready to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature developments
	will be made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain
	it from source control: https://www.mediawiki.org/wiki/Download_from_SVN

	== Changes since 1.11.0rc1 ==

	A possible HTML/XSS injection vector in the API pretty-printing mode has been
	found and fixed.

	The vulnerability may be worked around in an unfixed version by simply
	disabling the API interface if it is not in use, by adding this to
	[[Manual:LocalSettings.php\|LocalSettings.php]]:<br />
	<code>[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;</code> <br />
	(This is the default setting in 1.8.x.)

	Not vulnerable versions:
	* 1.11 >= 1.11.0
	* 1.10 >= 1.10.2
	* 1.9 >= 1.9.4
	* 1.8 >= 1.8.5

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.1
	* 1.9 <= 1.9.3
	* 1.8 <= 1.8.4 (if [[Manual:$wgEnableAPI\|$wgEnableAPI]] has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the faulty
	function, however the [[Extension:BotQuery\|BotQuery extension]] is similarly
	vulnerable unless updated to the latest SVN version.

	== Configuration changes since 1.10 ==

	* $wgThumbUpright - Adjust width of upright images when parameter 'upright' is
	used
	* $wgAddGroups, $wgRemoveGroups - Finer control over who can assign which
	usergroups
	* $wgEnotifImpersonal, $wgEnotifUseJobQ - Bulk mail options for large sites
	* $wgShowHostnames - Expose server host names through the API and HTML comments
	* $wgSaveDeletedFiles has been removed, the feature is now enabled
	unconditionally

	== New features since 1.10 ==

	* Introducing new image keyword 'upright' and corresponding variable
	$wgThumbUpright. This allows better proportional view of upright images
	related to landscape images on a page without nailing the width of upright
	images to a fix value which makes views for anon unproportional and user
	preferences useless
	* (bug 6072) Introducing 'border' keyword to the [[Image:]] syntax
	* Introducing 'frameless' keyword to [[Image:]] syntax which respects the
	user preferences for image width like 'thumb' but without a frame.

	when viewing the current revision of a page, if available
	* (bug 8890) Enable wiki text for "license" message
	* Throw a showstopper exception when a hook function fails to return a value.
	Forgetting to give a 'true' return value is a very common error which tends
	to cause hard-to-track-down interactions between extensions.
	* Use $wgJobClasses to determine the correct Job to instantiate for a particular
	queued task; allows extensions to introduce custom jobs
	* (bug 10326) AJAX-based page watching and unwatching has been cleaned up and

	phisticated handheld browser.
	* (bug 3173) Option to offer exported pages as a download, rather than
	displaying inline, as in most browsers

	== MediaWiki 1.10 ==

	== MediaWiki 1.10.4 ==

	March 2, 2008

	* Correction for API path fix, broken in 1.10.3

	== MediaWiki 1.10.3 ==

	January 23, 2008

	This is a security update to the Winter 2007 quarterly release. A potential
	XSS injection vector affecting api.php only for Microsoft Internet Explorer
	users has been closed.


	To work around the vulnerability without upgrading, you may disable the API if
	you don't need it:

	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	Not vulnerable versions:
	* 1.12 or later
	* 1.11 >= 1.11.1
	* 1.10 >= 1.10.3
	* 1.9 >= 1.9.5
	* 1.8 any version (if $wgEnableAPI has been left off)

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.2
	* 1.9 <= 1.9.4
	* 1.8 any version (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the API
	functionality, however the BotQuery extension is similarly vulnerable unless
	updated to the latest SVN version.

	== MediaWiki 1.10.2 ==
	September 10, 2007

	This is a security fix update to the Spring 2007 quarterly release snapshot. A
	possible HTML/XSS injection vector in the API pretty-printing mode has been
	found and fixed.

	The vulnerability may be worked around in an unfixed version by simply
	disabling the API interface if it is not in use, by adding this to
	LocalSettings.php:
	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	Not vulnerable versions:
	* 1.11 >= 1.11.0
	* 1.10 >= 1.10.2
	* 1.9 >= 1.9.4
	* 1.8 >= 1.8.5

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.1
	* 1.9 <= 1.9.3
	* 1.8 <= 1.8.4 (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the faulty
	function, however the BotQuery extension is similarly vulnerable unless updated
	to the latest SVN version.

	== MediaWiki 1.10.1 ==
	July 13, 2007

	This is a bugfix update to the Spring 2007 quarterly release snapshot. A number
	of fixes to improve compatibility with PostgreSQL, some versions of MySQL, and

	extended configuration format, e.g. "5;/tmp"

	== MediaWiki 1.10.0 ==
	May 9, 2007

	THIS IS A RELEASE CANDIDATE MADE AVAILABLE FOR TESTING!
	A FINAL 1.10.0 RELEASE WILL APPEAR WITHIN A FEW DAYS.

	Changes since 1.10.0rc1:
	* Various l10n fixes and updates
	* Fix for upgrade of page_restrictions table
	* (bug [[bugzilla:9780\|9780]]) Fix normalization of titles with initial colon
	followed by whitespace
	* Fix for regression in upload: wrong size info saved into image table
	* Avoid cyclic stub problems when authorization hooks do funny things with the
	user and the database at load time

	== MediaWiki 1.10.0rc1 ==
	This is the Spring 2007 branch release of MediaWiki.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept
	"ready to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature developments
	will be made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain
	it from source control: https://www.mediawiki.org/wiki/Download_from_SVN

	== Configuration changes ==

	* A new switch $wgCommandLineDarkBg used by maintenance scripts
	(parserTests.php). It lets you specify if your terminal use a dark background,
	the colorized output will be made lighter making things easier to read.
	* The minimum permissions needed to edit a page in each namespace can now be
	customized via the $wgNamespaceProtection array. By default, editing pages in
	the MediaWiki namespace requires "editinterface" permission, as before.
	* Allow restriction of autoconfirmed permission by edit count. New global
	setting $wgAutoConfirmCount (defaulting to zero, naturally).
	* Added rate limiter for Special:Emailuser
	* Private logs can now be created using $wgLogRestrictions
	* (Bug 8590) limited HTML is now always enabled ($wgUserHtml = true).
	* Deprecated $wgUseImageResize, thumbnailing will be enabled unconditionally.

	== New features since 1.9 ==

	* (bug 6937) Introduce "statistics-footer" message, appended to
	Special:Statistics
	* (bug 6638) List block flags in block log entries
	* (bugs 5051, 5376) Tooltips and accesskeys no longer require JavaScript
	* Added SkinTemplateOutputPageBeforeExec hook before SkinTemplate::outputPage()
	starts page output
	(http://lists.wikimedia.org/pipermail/wikitech-l/2007-January/028554.html)
	* Introduce "cascading protection" -- implicit protection on pages transcluded
	into a page protected with this option enabled
	* (bug 8567) Added hook RawPageViewBeforeOutput just before the text is blown
	out in action=raw, so extensions might influence the output.
	* (bug 3446) Add user preference to hide page content below diffs, can be
	overridden by adding diffonly=1 or diffonly=0 to the URL of the diff page
	* Add 'purge' privilege to replace the hardcoded check for login state in
	determining whether action=purge can be done via GET. Switching the
	permission on for anons can be helpful for benchmarking.

	"semi protected".
	* (bug 4133) Allow page protections to be made with an expiry date, in the same
	format as block expiry dates. Existing protections are assumed to be infinite,
	as are protections made with the new field left blank.

	keywords
	* (bug 6987) Allow perrow, widths, and heights attributes for <gallery>
	* (bug 3678) Allow disabling MediaWiki:Aboutsite in the same way as
	MediaWiki:Disclaimers; Also means that if any of the footer links are
	disabled in the wiki's default language (by setting to "-"), they'll also
	be disabled in other languages too (e.g. if the user specifies uselang=fr).

	* Partial support for Flash cross-domain-policy filtering.

	dump-based installations, avoiding PHP warnings when NUMBEROFARTICLES

	image

	PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
	http://bugs.php.net/bug.php?id=34879
	Upgrade affected systems to PHP 5.1 or higher.

	MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
	At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.


	== Upgrading ==

	1.10 has several database changes since 1.9, and will not work without schema
	updates.

	If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
	new database fields are filled with data.

	If you are upgrading from MediaWiki 1.4.x or earlier, some major database
	changes are made, and there is a slightly higher chance that things could
	break. Don't forget to always back up your database before upgrading!

	See the file UPGRADE for more detailed upgrade instructions.

	= MediaWiki release notes =
	Security reminder: MediaWiki does not require PHP's register_globals
	setting since version 1.2.0. If you have it on, turn it off if you can.

	= MediaWiki 1.9 =

	== MediaWiki 1.9.6 ==

	March 2, 2008

	* Correction for API path fix, broken in 1.9.5

	== MediaWiki 1.9.5 ==

	January 23, 2008

	This is a security update to the Winter 2007 quarterly release. A potential XSS
	injection vector affecting api.php only for Microsoft Internet Explorer users
	has been closed.


	To work around the vulnerability without upgrading, you may disable the API if
	you don't need it:

	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	Not vulnerable versions:
	* 1.12 or later
	* 1.11 >= 1.11.1
	* 1.10 >= 1.10.3
	* 1.9 >= 1.9.5
	* 1.8 any version (if $wgEnableAPI has been left off)

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.2
	* 1.9 <= 1.9.4
	* 1.8 any version (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the API
	functionality, however the BotQuery extension is similarly vulnerable unless
	updated to the latest SVN version.

	== MediaWiki 1.9.4 ==

	September 10, 2007

	This is a security and bug fix update to the Winter 2007 quarterly release.
	Minor compatibility fixes for IIS 5 are included.

	* (bug [[bugzilla:8847\|8847]]) Strip spurious #fragments from request URI to
	fix redirect loops on some server configurations
	* A possible HTML/XSS injection vector in the API pretty-printing mode has been
	found and fixed.

	The vulnerability may be worked around in an unfixed version by simply
	disabling the API interface if it is not in use, by adding this to
	LocalSettings.php:

	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	Not vulnerable versions:
	* 1.11 >= 1.11.0
	* 1.10 >= 1.10.2
	* 1.9 >= 1.9.4
	* 1.8 >= 1.8.5

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.1
	* 1.9 <= 1.9.3
	* 1.8 <= 1.8.4 (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the faulty
	function, however the BotQuery extension is similarly vulnerable unless updated
	to the latest SVN version.

	== MediaWiki 1.9.3 ==

	February 20, 2007

	This is a security and bug-fix update to the Winter 2007 quarterly release.
	Minor compatibility fixes for IIS and PostgreSQL are included.

	An XSS injection vulnerability based on Microsoft Internet Explorer's UTF-7
	charset autodetection was located in the AJAX support module, affecting MSIE
	users on MediaWiki 1.6.x and up when the optional setting $wgUseAjax is enabled.

	If you are using an extension based on the optional Ajax module, either disable
	it or upgrade to a version containing the fix:

	* 1.9: fixed in 1.9.3
	* 1.8: fixed in 1.8.4
	* 1.7: fixed in 1.7.3
	* 1.6: fixed in 1.6.10

	There is no known danger in the default configuration, with ''$wgUseAjax'' off.

	* ([[mediazilla:8992\|8992]]) Fix a remaining raw use of REQUEST_URI in history
	* ([[mediazilla:8984\|8984]]) Fix a database error in
	Special:Recentchangeslinked when using the PostgreSQL database.
	* Add ''charset'' to Content-Type headers on various HTTP error responses to
	forestall additional UTF-7-autodetect XSS issues. PHP sends only ''text/html''
	by default when the script didn't specify more details, which some
	inconsiderate browsers consider a license to autodetect the deadly,
	hard-to-escape UTF-7. This fixes an issue with the Ajax interface error message
	on MSIE when ''$wgUseAjax'' is enabled (not default configuration); this UTF-7
	variant on a previously fixed attack vector was discovered by Moshe BA from
	BugSec: [http://www.bugsec.com/articles.php?Security=24
	http://www.bugsec.com/articles.php?Security=24]
	* Trackback responses now specify XML content type

	== MediaWiki 1.9.2 ==

	February 4, 2007

	This is a bug-fix update that fixes some installation and other minor issues
	with the 1.9.1 release as well as a security issue which was introduced in the
	1.9 branch.

	JavaScript code which regenerated the "sortable tables" feature did not
	properly sanitize input, leading to an HTML injection vulnerability.

	* ([[mediazilla:8774\|8774]]) Fix path for GNU FDL rights icon on new installs
	* ([[mediazilla:8819\|8819]]) Fix full path disclosure with skins dependencies
	* ([[mediazilla:8819\|8819]]) Fixed data-loss bug in compressOld batch text
	compression affecting pages which had null edits (move, protect, etc) as second
	edit in a batch group. Isolated and patched by Travis Derouin.
	* Security fix for sortable tables JavaScript

	== MediaWiki 1.9.1 ==

	January 24, 2007

	This is a bug-fix update that fixes some installation and upgrade issues with
	the original 1.9.0 release.

	* ([[mediazilla:3000\|3000]]) Fall back to SCRIPT_NAME plus QUERY_STRING when
	REQUEST_URI is not available, as on IIS with PHP-CGI
	* Security fix for DjVu images. (Only affects servers where .djvu file uploads
	are enabled and ''$wgDjvuToXML'' is set.)
	* ([[mediazilla:8638\|8638]]) Fix update from 1.4 and earlier
	* ([[mediazilla:8641\|8641]]) Fix order of updates to ipblocks table for updates
	from <=1.7
	* ([[mediazilla:8673\|8673]]) Minor fix for web service API content-type header
	* Fix API revision list on PHP 5.2.1; bad reference assignment
	* Fixed up the AjaxSearch
	* Exclude settings files when generating documentation. That could expose the
	database user and password to remote users.
	* ar: fix the 'create a new page' on search page when no exact match found
	* Correct tooltip accesskey hint for Opera on the Macintosh (uses Shift-Esc-,
	not Ctrl-).
	* ([[mediazilla:8719\|8719]]) Firefox release notes lie! Fix tooltips for
	Firefox 2 on x11; accesskeys default settings appear to be same as Windows.

	== Changes since 1.8 ==

	* Various fixes related to the blocking change re: autoblocks. On inserting
	an IP block, the ipb_enable_autoblock field is now automagically blanked,

	Additional tables 'testrun' and 'testitem' are in maintenance/testRunner.sql,
	source this and pass --record option to parserTests.php
	* Make the set of default parser test input files extensible via
	$wgParserTestFiles. This can now be appended to by extensions or local
	configuration files so that extension or custom tests can be automatically
	run along with the main batch.
	* Run PHP install version checks on update.php so command-line updaters see
	new version requirements
	* Do a check for the PHP 5.0.x 64-bit bug, since this is much more disruptive
	as of MW 1.8 than it used to be. Install or upgrade now aborts with a
	warning and a request to upgrade.
	* (bug 6440) Updated indexes to improve backlinking queries (links, templates,
	images)
	* Switched 'anon-only' block mode to default for IP blocks
	* (bug 3687, 7892) Add distinct heading for media files in category display,
	with count.

	$wgUseSiteJs is enabled, in addition to (if applicable) MediaWiki:Monobook.js
	and user JS subpages.
	* (bug 7918) "Templates used on this page" changes during preview to reflect
	any added or removed templates, and works as expected for section edits.
	* (bug 7919) "Templates used on this page" is now shown for read-only pages.
	* (bug 7688) When viewing diff, section anchors in autosummary jump to section
	on current page instead of loading the latest version.
	* (bug 7970) Use current connection explicitly on Database::getServerVersion
	* (bug 2001) Tables with class="sortable" can now be dynamically sorted via
	JavaScript.
	* Added autosummary for new pages with 500 or less characters, and refactor
	the autosummary code so it's all done in one function. doEdit is getting too
	big!
	* (bug 7554) The correct MIME type for SVG images is now displayed on the
	image page (image/svg+xml, not image/svg).
	* (bug 7883) Added autoblock whitelisting feature, using which specific ranges
	can be protected from autoblocking. These ranges are specified, in list
	format, in the autoblock_whitelist system message.
	* Added placeholders for text injection by hooks to EditPage.php
	* (bug 8009) Automatic edit summary for redirects is not filled for edits in
	existing pages
	* Installer support for experimental MySQL 4.1/5.0 binary-safe schema
	* Use INSERT IGNORE for db-based BagOStuff add/insert, for more memcache-like
	behavior when keys already exist on add (instead of dying with an error...)
	* Add a hook 'UploadForm:initial' before the upload form is generated, and two
	member variable for text injection into the form, which can be filled by the
	hooks.
	* (bug 6295) Add a "revision patching" functionality, where an edit can be
	undone
	(with a functionality similar to diff rev1 rev2 \| patch -R rev3 -o rev3).
	This is triggered by including &undo=revid in an edit URL. A link to a URL
	that will undo a given edit is shown on NEW revision headers on diff pages.
	The link leads to a "Show Changes" page showing what will be done to undo the
	edit.
	* Fix display of link in "already rolled back" message for image/category pages
	* (bug 6016) Left-aligned images should stack vertically, like right-aligned

	* Add AuthPluginSetup hook to override $wgAuth after configuration
	* Fix regression in authentication hook auto-creation on login
	* (bug 8110) Allow spaces in ISBNs
	* (bug 8024) Introduce "send me copies of emails I send to others" preference
	* Added 'EditPage::attemptSave' hook before an article is saved.
	* (bug 8083) Applied patch for sk localisation
	* Add a backslash character to the edit token, to prevent edits via certain
	broken proxies that mangle such characters in form submissions
	* (bug 7461) Allow overwriting pages using importTextFile.php
	* (bug 7946) importTextFile.php doesn't perform pre-save transform
	* (bug 8117) {{REVISIONTIMESTAMP}} showed weird default if $wgLocalTZoffset set;
	now uses current time for previews and if timestamp can't be loaded from DB
	* {{REVISIONTIMESTAMP}} now uses site local timezone instead of user timezone
	to ensure consistent behavior
	* {{REVISIONTIMESTAMP}} and friends should now work on non-MySQL backends
	* (bug 7671) Observe canonical media namespace prefix in Linker::formatComment
	* Added js variable wgCurRevisionId to the output
	* (bug 8141) Cleanup of Parser::doTableStuff, patch by AzaTht
	* (bug 8042) Make miser mode caching limits settable via $wgQueryCacheLimit
	instead of hardcoding to 1000
	* Enable QueryPage classes to override list formatting
	* (bug 5485) Show number of intervening revisions in diff view
	* (bug 8100) Fix XHTML validity in Taiwanese localization
	* Added redirect to section feature. Use it wisely.
	* Added a configuration variable allowing the "break out of framesets" feature
	to be switched on and off ($wgBreakFrames). Off by default.
	* Allow Xml::check() $attribs parameter to override 'value' attribute
	* DB schema change: added two columns (rc_old_len and rc_new_len) to the
	recentchanges table to store the text lengths before and after the edit
	* (bug 1085) Made Special:Recentchanges show the character difference between
	the changed revisions
	* Removed a redundant <strong> tag from diff pages that was causing display
	issues for some users
	* (bug 8203) The keyboard shortcut for "log out" was removed, because users
	were pressing it when they intended to press the shortcut for "preview".
	* (bug 8148) Handle non-removable output buffers gracefully when cleaning
	buffers for HTTP 304 responses, StreamFile, and Special:Export.
	Duplicated code merged into wfResetOutputBuffers() and wfClearOutputBuffers()
	* Special:AllPages : 'next page' link now point to the first title of the next
	chunk instead of pointing to the last title of current chunk.
	* (bug 4673) Special:AllPages : add a 'previous' link (new message 'prevpage')
	* (bug 8121) wfRandom() was not between 0 and 1
	* Add static method Parser::createAssocArgs($args), so parser functions can
	use the same code to parse arguments as the templates do.
	* Change behavior of logins using the temporary e-mailed password (as stored
	in user_newpassword hash field). Instead of just logging in silently and
	leaving the previous user_password field in place indefinitely, the user
	is now prompted to set a new password.

	The password-changing form is at Special:Resetpass; currently it's only
	usable for changing from the temporary password during login, but it
	could perhaps be generalized, replacing the subform in preferences.

	Once the new password is set successfully, the temporary password is wiped
	so it cannot be used to login a second time, and the login process
	is completed.
	* Suppress 'mail new password' button on login form if $wgAuth forbids
	changing user passwords; it wouldn't work very well...
	* Consolidate password length checks and $wgAuth manipulation into
	User::setPassword() to avoid duplicate code in different places
	that set passwords.
	* User::setPassword() now throws PasswordError exceptions if the password
	is illegal or cannot be set via $wgAuth. These can be caught and a human-
	readable error message displayed by UI code.
	* Added Title::isSubpage()
	* (bug 8241) Don't consider user pages of User:Foo.css to be CSS subpages
	* Set an explicit class on framed thumbnail inner divs and images, changed some
	CSS to use these instead of using descendent selectors.
	* Accept null parameter to User::setPassword() as indicating the password
	field should be cleared to an unusable state. Login will only be possible
	after the password is reset, for instance by e-mail.
	* (bug 6394) Invalidate the password set for "by e-mail" account creations
	to avoid accidental empty password creations.
	* Made the show change size function work on page moves, page creations, and
	log entries. Also fixed it in the javascript recentchanges.
	* (bug 8239) correctly get 50 new contributions when clicking '(50 next)'
	* (bug 2259) Fix old regression where e-mail addresses were no longer
	confirmed on login with mailed password.
	* Add a notification about the confirmation mail sent during account
	creation, so people don't immediately go off to request a second one.
	* Add a warning on Special:Confirmemail if a code was already sent and has
	not yet expired.
	* Add user_editcount field to provide data for heuristics on account use.
	Incremented on edit, with lazy initialization from past revision data.
	Can batch-initialize with maintenance/initEditCount.php (not yet friendly
	to replication environments, this will do all accounts in one query).
	* Allow raw SQL subsections in Database::update() SET portion as well as
	for WHERE portion. Handy for increments and such.
	* User::getOption now accept a default value to override default user values
	this makes it consistent with WebRequest::get* methods. Corrected code in
	various places accordingly.
	* (bug 8264) Fix JavaScript global vars for XHTML mode
	* Make $wgSiteNotice value wikitext again, for consistency with editable
	MediaWiki:Sitenotice and MediaWiki:Anonnotice.
	* (bug 8044) When redirecting from the canonical name of the special page
	to the localised one, parameters/subpages are omitted
	* (bug 8164) Special:Booksources should use GET for form submission
	* Rewrite Special:Booksources to clean up interface and remove redundant code
	* (bug 7925) Change Special:Allmessages message name filter javascript to be
	a bit more responsive and easier on the CPU
	* (bug 4488) Support watching pages on deletion; introduces new user preference
	* Minor restructuring of Special:Preferences; "watch pages I edit" and "watch
	pages I create" options now accessible under "Watchlist" options
	* (bug 8153) <nowiki> doesn't work in site notice
	* (bug 6690) wfMsgNoTrans() transforms messages
	* (bug 8274) Wrap edit tools in a <div> with a specified class
	* Detect PHP 5.0.x 64-bit bug and abort in WebStart.php; too many things break
	mysteriously otherwise (detection code copied from install-utils.inc)
	* (bug 8295) Change handling of <center> tags in doBlockLevels() to match that
	of <div>
	* (bug 8110) Make magic ISBN linking stricter: only match ten-digit sequences
	(plus optional ISBN-13 prefix) with no immediately following alphanumeric
	character, disallow multiple consecutive internal redirects
	* (bug 2785) Accept optional colon prefix in links when formatting comments
	* Don't show "you can view and copy the source of this page" message for
	pages which don't exist
	* (bug 8310) Blank line added to top of 'post' when page is blank
	* (bug 8109) Template parameters ignored in "recentchangestext"
	* Gracefully skip redirect-to-fragment on WebKit versions less than 420;
	it messes up on current versions of Safari but is ok in the latest
	nightlies. Checking the version number will allow it to automatically
	work when new releases of Safari appear.
	* Fix regression in thumb styles; size and padding didn't match with
	new arrangement.
	* (bug 8333) Fix quick user data update on login password change on
	replication database setups. User data is now pulled from master
	instead of slave in User::loadFromDatabase, ensuring that it is
	fresh and accurate when read and then saved back into cache.
	This was breaking with the Special:Rename operation which
	automatically logs the user in with the new password after changing
	it; pulling from slave meant the record was often not the updated
	one.
	* (bug 8335) Set image width to the first valid parameter found.
	* (bug 8350) Fix watchlist viewing bug when using Postgres.
	* (bug 6603) When warning about invalid file extensions, output the bit
	of the extension we actually checked
	* (bug 7669) Drop defaults on BLOB/TEXT columns for better compatibility
	with MySQL's strict mode, often enabled by the Windows installer.
	The defaults are ignored anyway when strict mode is off...
	* (bug 7685) Use explicit values for ar_text and ar_flags when deleting,
	for better compatibility with MySQL's strict mode
	* Update default interwiki values to reflect changed location of ursine:
	* (bug 5411) Remove autopatrol preference
	* Users who have the "autopatrol" permission will have their edits marked as
	patrolled automatically
	* Users who do not have the "autopatrol" permission will no longer be able
	to mark their own edits as patrolled
	* Introduce 'PingLimiter' hook; see docs/hooks.txt for more information
	* (bug 532) Tweaked alt text for some interface messages
	* (bug 8231) Gave useful alt text to the main <img> on image pages
	* (bug 371) Remove alt text for "Enlarge" icon on thumbnails
	* Initialize user_editcount to 0 instead of NULL for newly created accounts
	* (bug 3696) Strip LRM and RLM characters from titles to work around the
	problem some people have where titles cut-and-pasted from lists include
	the bidi override characters appended to the lists.
	A more thorough blacklist for forbidden and translatable characters would
	be wise, though, as might a cleaner method for the lists in the first place.
	* Fix regression in email password resets on read-restricted sites
	* Set tabindex on fields in deletion form so you don't have to tab through
	the links in the sitenotice
	* (bug 8271) Show full time and date on viewer for individual deleted
	revisions
	* (bug 8214) Output file size limit and actual file size in appropriate units
	on Special:Upload
	* (bug 8016) Purge objectcache table during upgrade processes - use the
	--nopurge option to prevent this when running maintenance/update.php
	* (bug 7612) Remove superfluous link to Special:Categories from result items
	on Special:Mostcategories
	* {{PLURAL:}} now handles formatted numbers correctly
	* (bug 8331) Added the change size value to watchlists; therefore made
	watchlists use RecentChange::newFromRow() instead of newFromCurRow()
	* (bug 8351) Fix undo for simple reverts
	* (bug 6856) User::clearNotification() does not respect read-only mode
	* (bug 6853) Use a checkbox on the installer form to indicate that a superuser
	account should be used; this is clearer than the old check which relied on
	the password never being an obscure value
	* Remove old unused watchlist cache, which was a leftover from the old schema
	where watchlists were more expensive to generate
	* Minor cosmetic changes to Special:Userrights
	* Added wgCanonicalSpecialPageName to JavaScript variables
	* Fix image deleting when using Postgres.
	* Output both source and destination titles in maintenance/moveBatch.php
	* Added basic parser tests for language variants
	* Enable selflinks and categories to be written in some of the language variants
	* Prevent conversion of JavaScript code in language variants
	* Output software version number in maintenance/parserTests.php
	* (bug 7169) Use Ajax to watch/unwatch articles if enabled
	* Make variant table caching a little more robust, using main language code
	in cache key. Probably this is still a bit wonky, though. Was breaking
	parser tests when Chinese tables were getting loaded into Serbian code.
	* (bug 8380) Be nicer about blank lines in deleteBatch.php
	* (bug 8401) Fix regression in SORBS lookup for some DNS setups
	* Use raw file descriptor in posix_isatty() check to avoid warning on
	Linux systems with at least some versions of PHP
	* (bug 5908) Allow overriding the default category sort key for all items on
	a page using {{DEFAULTSORT}}

	* (bug 8427) MonoBook RTL IE 7.0 tweaks failed when sidebar's navigation
	section is renamed; no longer relies on first section name
	* Stabilize client-side table sorting even if the underlying Javascript sort()
	implementation is unstable
	* Add hook for extensions to add user information to the panel in preferences,
	next to the user name and ID.
	* (bug 8392) Display protection status of transcluded pages in the edit page
	template list. Patch by Fyren, with i18n naming tweak.
	* Fix for interwiki transclusion where target wiki uses query string for title
	* Resolve namespaces on interwiki Title objects using canonical namespace names
	if possible (should not happen, though, outside interwiki transclusion... and
	maybe not even then, but it does)
	* (bug 8447) Fix SQL typo breaking non-default $wgHitcounterUpdateFreq
	* Do not allow previews of deleted images to be cached
	* Add global variable $wgDefaultLanguageVariant used to set the default language
	variant of a wiki to something different than the main language code
	* Add 'variant' option to parserTests - runs test with the given variant as
	preferred, utilize it for more parser tests of language variants code
	* (bug 6503) Fix bug that stopped certain irrelevant links from being hidden
	for printing
	* Avoid PHP warning in Creative Commons metadata when a creative commons
	license is not actually set up
	* (bug 8463) Don't print external link icons for Monobook
	* (bug 8461) Support watching pages on move
	* (bug 8041) Work around bug with debug_backtrace when Zend Optimizer is
	loaded by skipping the function. Use wfDebugBacktrace() wrapper function.
	* Reduce config file clutter by setting various script and upload paths
	based on $IP or $wgScriptPath in Setup.php. They can still be explicitly
	overridden in LocalSettings.php if desired...
	* Attempt to detect redirect loops for the canonical title redirect, and
	give some hints to the poor confused administrator.
	* Introduce new flag 'R' - raw output for language variant escape tags
	* Advise users when updates for a query page have been disabled using
	$wgDisableQueryPageUpdate
	* (bug 8413) Improve comments for $wgNamespaceRobotPolicies
	* (bug 8330) Show "bytes" suffix on recent changes diff counter

	* (bug 8489) Support basic links in <gallery> caption attribute
	* (bug 8485) Correct Lingala number formatting
	* The MediaWiki namespace is no longer pre-filled with default messages on
	install. All default messages will be removed from the MediaWiki namespace
	on upgrade.
	* Recentchanges RSS/Atom feeds now use a separate message for the description
	to avoid cluttering it with useless wiki formatting
	* (bug 8417) Handle EXIF unknown dates
	* (bug 8372) Return nothing on empty <math> tags.
	* New maintenance script to show the cached statistics : showStats.php.
	* Count deleted edits when regenerating total edits in maintenance/initStats.php

	* (bug 7667) allow XHTML namespaces customization
	* (bug 8531) Correct local name of Lingála (patch by Raymond)
	* Fix regression with default lock file and cache directories; threw visible
	warning with open_basedir


	== 1.8 Compatibility changes ==

	=== Zend Optimizer ===

	A bug in some versions of PHP 5 and Zend Optimizer which was triggered under
	MediaWiki 1.8.x has been worked around by disabling some internal debugging
	features when Zend Optimizer is loaded. This should solve some common
	"blank page" problems.

	=== PHP 5.0 64-bit ===

	MediaWiki now checks for a condition where PHP 5.0.x corrupts array data
	on 64-bit systems and warns you to upgrade PHP to solve the problem. This
	bug causes Special: pages to fail on affected systems under MediaWiki 1.8
	and higher, and subtler data corruption on earlier versions.

	The only known workaround is to upgrade PHP to 5.1 or later, which you
	probably should do anyway for security reasons!

	=== MySQL 5 ===

	MediaWiki should now install and run correctly on MySQL 5.0 and higher when
	MySQL's "strict mode" is enabled. (This is now the default for many Windows
	installations, though it seems to remain off by default on Unix.)

	This fixes errors about "cannot default default value for BLOB/TEXT fields".

	=== ImageMagick ===

	Note that ImageMagick older than 6.x may no longer work for image resizing
	due to use of the -thumbnail option.


	== 1.8 Behavior changes ==

	=== Localized special pages ===

	The names of Special: pages can now be localized, so links and URLs to them
	are more legible in languages that aren't English.

	Not all languages have included localized names yet.

	=== E-mail password ===

	Users are now required to set a new password for themselves when they first
	log in with a newly generated e-mailed password.

	Requesting passwords frequently is prevented to reduce abusive mailbombing.

	=== Undo revision ===

	An "undo" link now appears in diff view for easier reverting of older edits.
	When GNU diff3 is available for edit conflict merging, this can make it much
	easier to "undo" the changes of an older edit when there are surrounding
	changes elsewhere in the page.

	The changes must be manually reviewed and approved, as with conventional
	full-revision reverts.

	=== Blocking ===

	User blocks can be set to disable the automatic blocking of IP addresses the
	account logs in with.


	== 1.8 Database changes ==

	* new 'redirect' table stores data on page redirects
	* new 'querycachetwo' table used for some cached special pages
	* 'ipblocks' table adds 'ipb_enable_autoblock'
	* 'recentchanges' table adds 'rc_old_len', 'rc_new_len' for size tracking
	* 'user' table has added 'user_newpass_time' and 'user_editcount' fields
	* some indexes have been updated on 'recentchanges'

	== 1.8 Configuration changes ==

	Several configuration options have changed since 1.8:

	=== $wgEnableAPI ===

	The experimental machine API interface is now enabled by default, read-only.
	You can disable it by setting $wgEnableAPI = false; in LocalSettings.php.

	=== $wgPathInfo ===

	The use of PATH_INFO (the text after the script name in 'index.php/Blah')
	is controlled by the $wgUsePathInfo setting. This is now explicitly disabled
	for CGI, apache2filter, and ISAPI configurations of PHP, for more consistency
	with the autodetection from the installer.

	In some rarer configurations you may have to switch $wgUsePathInfo from false
	to true or, perhaps, from true to false to make things work properly if bad
	PATH_INFO data comes through the server.

	The wiki now tries to detect this condition and should show you an error
	message describing what to change instead of sending the browser into an
	infinite redirect loop.

	=== $wgScript and other path settings ===

	The following configuration variables are now automatically set in Setup.php
	if they are not overridden in LocalSettings.php:

	from $wgScriptPath:
	+ $wgScript
	\| \- $wgArticlePath
	+ $wgRedirectScript
	+ $wgStylePath
	+ $wgUploadPath
	\- $wgLogo
	+ $wgMathPath

	from $IP:
	- $wgStyleDirectory
	+ $wgUploadDirectory
	\- $wgMathDirectory
	+ $wgTmpDirectory

	Newly generated configuration files will by default include only $wgScriptPath
	(hardcoded from the installer) and $IP (detected at runtime).

	Old configuration files which specify all these values explicitly should
	continue to work just fine, but if you use the defaults you can remove them
	to reduce clutter.

	=== $wgGroupPermissions ===

	The sysop group now holds the "autopatrol" and "ipblock-exempt" rights by
	default.

	"autopatrol" replaces the preference for marking ones own edits patrolled
	by default; users holding this permission will automatically have their
	edits patrolled, while others cannot mark their own edits as patrolled
	even if they have patrolling rights.

	"ipblock-exempt" excludes the user from IP blocks; accounts which are blocked
	explicitly by name will still be blocked, however. This is given to sysops
	to minimize annoyance from accidental "collateral damage"; remember that a
	sysop will be able to lift the block if they desire.

	The bot group now holds the "nominornewtalk" right. A user with this right
	will not trigger new message notifications when making minor edits to user
	talk pages. This is meant to minimize annoyance from maintenance bot
	processes.

	=== $wgUseWatchlistCache ===

	Watchlist caching has been removed. The feature was not maintained, and has
	been unnecessary since switching to the 'recentchanges' database table
	reduced server pressure for Wikipedia's watchlists.

	=== $wgBreakFrames ===

	MediaWiki in the past attempted to detect when it was embedded in a frameset
	and "break out" of it, assuming it to be hostile.

	This behavior is now disabled by default, but can be reenabled by setting
	$wgBreakFrames to true in LocalSettings.php.


	== 1.8 New settings ==

	=== $wgVariantArticlePath ===

	For languages with script variant support (Chinese, Serbian, and others),
	it's possible to use alternate URL paths to select the variant for article
	display, setting $wgVariantArticlePath.

	Documentation for this setting would be useful.

	=== $wgMaxMsgCacheEntrySize ===

	The message cache can now skip items larger than a given size; this allows
	it to better handle the primary caching case when large CSS and JS blobs are
	present.

	=== $wgStyleVersion ===

	When making significant changes to skin stylesheets and JavaScript files,
	you can append a string to this variable to tweak the generated URLs,
	forcing newly rendered pages to bring in a fresh version despite server-
	or browser-side caching.

	Normally this will be set in the course of MediaWiki development, but
	if doing development on a custom skin you may wish to poke it as well.

	=== $wgRCShowChangedSize ===

	Special:Recentchanges and Special:Watchlist now show the number of bytes
	added or removed to an article to give an idea of the size of the edit.
	This information was previously available only in the IRC update feeds.

	To disable this site-wide, set $wgRCShowChangedSize to false.
	(Individual users can suppress the data in custom CSS.)

	Adjust $wgRCChangedSizeThreshold to trigger highlighting of particularly
	large changes.

	The formatting of the size figure can be adjusted through the
	[[MediaWiki:Rc-change-size]] message.

	=== $wgQueryCacheLimit ===

	The number of rows stored for "expensive" special pages in miser mode
	can now be adjusted up or down from the default 1000.

	=== $wgDisableQueryPageUpdate ===

	Individual "expensive" special pages can be skipped in processing by
	updateSpecialPages if added to this list.

	=== $wgSorbsUrl ===

	The base hostname for the DNS-based proxy blacklist can now be overridden
	when $wgEnableSorbs is set, to use a different blacklist instead of SORBS.
	The blacklist would need to respond the same was as SORBS; any positive
	response will be taken as a proxy.

	=== $wgAjaxWatch ===

	Experimental AJAX mode for the watch/unwatch tabs to execute inline.
	Does not include the UI messages describing how to reach the watchlist,
	so you may not want it on a general-audience site just yet.

	=== $wgParserTestFiles ===

	MediaWiki's parser test suite can now be expanded with additional test
	files. Custom extensions can add their test files to this array, and
	they will be run along with the main tests by maintenance/parserTests.php

	= MediaWiki 1.8=

	== MediaWiki 1.8.5 ==

	September 10, 2007

	This is a security fix update to the Fall 2006 quarterly release snapshot. A
	possible HTML/XSS injection vector in the API pretty-printing mode has been
	found and fixed.

	The vulnerability may be worked around in an unfixed version by simply
	disabling the API interface if it is not in use, by adding this to
	LocalSettings.php:

	:[[Manual:$wgEnableAPI\|$wgEnableAPI]] = false;

	(This is the default setting in 1.8.x.)

	Not vulnerable versions:
	* 1.11 >= 1.11.0
	* 1.10 >= 1.10.2
	* 1.9 >= 1.9.4
	* 1.8 >= 1.8.5

	Vulnerable versions:
	* 1.11 <= 1.11.0rc1
	* 1.10 <= 1.10.1
	* 1.9 <= 1.9.3
	* 1.8 <= 1.8.4 (if $wgEnableAPI has been switched on)

	MediaWiki 1.7 and below are not affected as they do not include the faulty
	function, however the BotQuery extension is similarly vulnerable unless updated
	to the latest SVN version.

	== MediaWiki 1.8.4 ==

	February 20, 2007

	This is a security and bug-fix update to the Fall 2006 quarterly release.

	An XSS injection vulnerability based on Microsoft Internet Explorer's UTF-7
	charset autodetection was located in the AJAX support module, affecting MSIE
	users on MediaWiki 1.6.x and up when the optional setting
	[[Manual:$wgUseAjax\|$wgUseAjax]] is enabled.

	If you are using an extension based on the optional Ajax module, either disable
	it or upgrade to a version containing the fix:
	* 1.9: fixed in 1.9.3
	* 1.8: fixed in 1.8.4
	* 1.7: fixed in 1.7.3
	* 1.6: fixed in 1.6.10

	There is no known danger in the default configuration, with $wgUseAjax off.

	* (bug [[bugzilla:8819\|8819]]) Fix full path disclosure with skins dependencies
	* Add 'charset' to Content-Type headers on various HTTP error responses to
	forestall additional UTF-7-autodetect XSS issues. PHP sends only 'text/html' by
	default when the script didn't specify more details, which some inconsiderate
	browsers consider a license to autodetect the deadly, hard-to-escape UTF-7.
	This fixes an issue with the Ajax interface error message on MSIE when
	[[Manual:$wgUseAjax\|$wgUseAjax]] is enabled (not default configuration); this
	UTF-7 variant on a previously fixed attack vector was discovered by Moshe BA
	from BugSec: http://www.bugsec.com/articles.php?Security=24
	* Trackback responses now specify XML content type

	== MediaWiki 1.8.3 ==

	January 9, 2007

	MediaWiki 1.8.3 fixes several issues in the Fall 2006 snapshot release:

	* ([[mediazilla:7831\|7831]]) Regression in AutoAuthenticate hook
	* Run PHP install version checks on update.php so command-line updaters see new
	version requirements
	* Do a check for the PHP 5.0.x 64-bit bug, since this is much more disruptive
	as of MW 1.8 than it used to be. Install or upgrade now aborts with a warning
	and a request to upgrade.
	* XSS fix in AJAX module

	An XSS injection vulnerability was located in the AJAX support module,
	affecting MediaWiki 1.6.x and up when the optional setting $wgUseAjax is
	enabled.

	There is no danger in the default configuration, with $wgUseAjax off.

	If you are using an extension based on the optional AJAX module, either disable
	it or upgrade to a version containing the fix:

	== MediaWiki 1.8.2 ==

	October 13, 2006

	MediaWiki 1.8.2 fixes several issues in the Fall 2006 snapshot release:

	* ([[mediazilla:7565\|7565]]) Fixed typos in German localisation
	* ([[mediazilla:7562\|7562]]) Fix non-ASCII namespaces on Windows/XAMPP servers

	== MediaWiki 1.8.1 ==

	October 11, 2006

	MediaWiki 1.8.1 fixes several issues in the Fall 2006 snapshot release:

	* Fix PHP notice and estimates for dumpBackup.php and friends
	* Improved register_globals paranoia checks
	* ([[mediazilla:7545\|7545]]) Fix PHP version check on install
	* Experimental web API disabled by default
	* Disable PHP exception backtrace printing unless $wgShowExceptionDetails is
	set. Backtraces may contain sensitive information in function call parameters.

	== MediaWiki 1.8.0 ==

	October 10, 2006

	This is the quarterly release snapshot for Fall 2006. While the code has been
	running on Wikipedia for some time, installation and upgrade bits may be less
	well tested. Bug fix releases may follow in the coming days or weeks.

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept "ready
	to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature development happen
	will be made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain it
	from source control: [[Download from SVN]]

	== Configuration changes ==
	* $wgUseETag, to enable/disable sending of HTTP ETag headers (default: disabled)
	* $wgLegalTitleChars now includes '+' by default for better compatibility with
	importing data dumps from Wikipedia
	* $wgDefaultUserOptions now includes all default option settings instead of
	only overrides.

	== Major new features ==
	* ([[mediazilla:7098\|7098]]) Add an option to disable/enable sending of HTTP
	ETag headers, as it seems to result in broken behaviour in combination with
	Squid 2.6 (disabled by default).
	* ([[mediazilla:550\|550]]) Allow blocks on anonymous users only.
	* ([[mediazilla:6420\|6420]]) Render thumbnails for DJVU images, support
	multipage DJVU display on image pages. Added new 'page=' thumbnail option to
	select a page from a multipage djvu for thumbnail generation.
	* Full Postgres support is now enabled. It requires version 8.1 or better, and
	needs to have both plpgsql and tsearch2 already installed.
	* ([[mediazilla:6386\|6386]]) fix grammatical errors in danish naming of talk
	namespaces.

	== Changes since 1.7 ==

	* Introduced AjaxResponse object, superceding AjaxCachePolicy
	* Changes to sajax_do_call: optionally accept an element to fill instead of a
	callback function; take the target function or element as a third parameter;
	pass the full XMLHttpRequest object to the handler function, instead of just
	the resultText value; use HTTP response codes to report errors.
	* (bug 6562) Removed unmaintained ParserXml.php for now
	* History paging overlap bug fixed
	* (bug 6586) Regression in "unblocked" subtitle
	* Don't put empty-page message into view-source when page text is blank
	* (bug 6587) Remove redundant "allnonarticles" message
	* Block improvements: Allow blocks on anonymous users only. Optionally allow
	or disallow account creation from blocked IP addresses. Prevent duplicate
	blocks. Fixed the problem of expiry and unblocking erroneously affecting
	multiple blocks. Fixed confusing lack of error message when a blocked user
	attempts to create an account. Fixed inefficiency of Special:Ipblocklist in
	the presence of large numbers of blocks; added indexes and implemented an
	indexed pager.
	* (bug 6448) Allow filtering of Special:Newpages according to username
	* (bug 6618) Improve permissions/error detection in Special:Lockdb
	* Quick hack for extension testing: parser test doesn't create new message
	cache object.
	* (bug 6299) Maintain parser's revision ID across recursive calls to fix
	{{REVISIONID}} when Cite extension is used
	* (bug 6622) Removed deprecated function Image::newFromTitle
	* (bug 6627) Fix regression in Special:Ipblocklist with table prefix
	* Removed forced dereferencements (new() returns a reference in PHP5)
	* Note about $wgUploadSizeWarning using byte
	* (bug 6592) Add most viewed pages summary to Special:Statistics
	* Pre-strip characters ignored in IDNs from URLs so they can't be used
	to break the blacklists for regular URLs
	* Fix regression in blocking of user accounts
	* (bug 6635) Fix regression searching for range blocks on Ipblocklist
	* Fix regression searching Ipblocklist with ugly URLs
	* (bug 6639) Use a consistent default for upload directories
	* Preserve entered reason when reporting unconfirmed lock on Special:Lockdb
	* (bug 6642) Don't offer to unlock the database when it isn't locked
	* cleanupTitles.php changed from --dry-run option to --fix, so default
	behavior is now a non-invasive check as with namespaceDupes.php
	* (bug 6660) Fix behavior of EditPage::blockedPage() when the article does
	not exist; now doesn't show the source box if the user hasn't provided it
	(blocked mid-edit) and the page doesn't exist
	* Improve default value of "blockedtext"
	* (bug 6680) Added localisation for Dutch bookstore list (nl)
	* Renamed maintainace script redundanttrans.php to unusedMessages.php - clearer
	usage
	* Fix regression which allowed some blocked users to create additional accounts
	* (bug 6657) Fix Hungarian linktrail
	* (bug 6751) Fix preview of blanked section with edit on first preview option
	* (bug 5456) Separate MediaWiki:Search into messages for both noun and verb,
	introduced 'MediaWiki:Searchbutton'

	== Compatibility ==
	MediaWiki 1.8 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.

	MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At
	this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.

	== Upgrading ==
	Some minor database changes have been made since 1.7:
	* new fields and indexes on ipblocks
	* index change on recentchanges

	Several changes from 1.5 and 1.6 do require updates to be run on upgrade. To
	ensure that these tables are filled with data, run refreshLinks.php after the
	upgrade.

	If you are upgrading from MediaWiki 1.4.x or earlier, some major database
	changes are made, and there is a slightly higher chance that things could
	break. Don't forget to always back up your database before upgrading!

	=== Caveats ===
	Some output, particularly involving user-supplied inline HTML, may not produce
	100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType
	= "application/xhtml+xml"; to test for remaining problem cases, but this is not
	recommended on live sites. (This must be set for MathML to display properly in
	Mozilla.)

	= MediaWiki 1.7=

	== MediaWiki 1.7.3 ==

	February 20, 2007

	This is a security and bug-fix update to the Summer 2006 quarterly release.

	An XSS injection vulnerability based on Microsoft Internet Explorer's UTF-7
	charset autodetection was located in the AJAX support module, affecting MSIE
	users on MediaWiki 1.6.x and up when the optional setting
	[[Manual:$wgUseAjax\|$wgUseAjax]] is enabled.

	If you are using an extension based on the optional Ajax module, either disable
	it or upgrade to a version containing the fix:

	* 1.9: fixed in 1.9.3
	* 1.8: fixed in 1.8.4
	* 1.7: fixed in 1.7.3
	* 1.6: fixed in 1.6.10

	There is no known danger in the default configuration, with
	[[Manual:$wgUseAjax\|$wgUseAjax]] off.

	* Add 'charset' to Content-Type headers on various HTTP error responses to
	forestall additional UTF-7-autodetect XSS issues. PHP sends only 'text/html' by
	default when the script didn't specify more details, which some inconsiderate
	browsers consider a license to autodetect the deadly, hard-to-escape UTF-7.
	This fixes an issue with the Ajax interface error message on MSIE when
	[[Manual:$wgUseAjax\|$wgUseAjax]] is enabled (not default configuration); this
	UTF-7 variant on a previously fixed attack vector was discovered by Moshe BA
	from BugSec: http://www.bugsec.com/articles.php?Security=24
	* Trackback responses now specify XML content type

	== MediaWiki 1.7.2 ==

	January 9, 2007

	* Note about $wgUploadSizeWarning using byte
	* Update to German bookstore list (de)
	* (bug [[bugzilla:6680\|6680]]) Added localisation for Dutch bookstore list (nl)
	* (bug [[bugzilla:6708\|6708]]) Minor updates to Russian translation (ru)
	* (bug [[bugzilla:6730\|6730]]) Clearer usage of message 'titlematch' in German
	translation (de)
	* Added direction mark to Special:Listredirects
	* XSS fix in AJAX module

	An XSS injection vulnerability was located in the AJAX support module,
	affecting MediaWiki 1.6.x and up when the optional setting
	[[Manual:$wgUseAjax\|$wgUseAjax]] is enabled.

	There is no danger in the default configuration, with
	[[Manual:$wgUseAjax\|$wgUseAjax]] off.

	If you are using an extension based on the optional AJAX module, either disable
	it or upgrade to a version containing the fix:

	* 1.9: fixed in 1.9.0rc2
	* 1.8: fixed in 1.8.3
	* 1.7: fixed in 1.7.2
	* 1.6: fixed in 1.6.9


	== MediaWiki 1.7.1 ==

	July 8, 2006

	MediaWiki 1.7.1 is a security and bugfix maintenance release of the Summer 2006
	snapshot:

	A potential HTML/JavaScript-injection vulnerability in a debugging script has
	been fixed. Only versions and configurations of PHP vulnerable to the $GLOBALS
	overwrite vulnerability are affected.

	As a workaround for existing installs, profileinfo.php may simply be deleted if
	it's not being used.

	* Fix for 'emailconfirmed' implicit user group
	* Fix for upgrades on some versions of MySQL 4.0.x
	* Fixed potential XSS in profileinfo.php
	* Installer now shows clear error message about old PHP versions rather than a
	confusing parse error

	== MediaWiki 1.7.0 ==
	July 6, 2006

	This is the quarterly release snapshot for Summer 2006. While the code
	has been running on Wikipedia for some time, installation and upgrade
	bits may be less well tested. Bug fix releases may follow in the coming
	days or weeks.

	MediaWiki is now using a "[[w:en:Continuous_integration\|continuous
	integration]]" development model with
	quarterly snapshot releases. The latest development code is always kept
	"ready to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature development happen
	will be made on the development trunk and appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can obtain
	it from source control: [[Download from SVN]]

	(XHTML 1.0 Transitional), while the replacement didn't catch all cases and
	could even result in invalid output from valid input.
	* (bug 4280) Use 'noindex,nofollow' instead of 'noindex,follow' for default
	meta robots tag on diff view and special pages. Should reduce impact of
	robots on scrolling special pages, diffs etc on sites where robots.txt
	doesn't forbid access.

	edit with 'preview on first edit' enabled.
	* (bug 6230) Regression fix: <nowiki> in [URL link text]

	* Allow fetching all revisions from transwiki Special:Import
	* Allow fetching all revisions from Special:Export GET request
	* Disable output buffering on Special:Export; should help with streaming
	large numbers of history items.

	Note that MediaWiki does not support the multibyte character sets where a
	"dumb" byte replacement can be actively dangerous; UTF-8 is always safe
	in this regard due to the bit patterns which make head and tail bytes
	distinct.

	== Compatibility ==
	MediaWiki 1.7 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.

	If you are unable to run PHP 5, you may have to stick with 1.6 for now.

	MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
	At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.

	Experimental Oracle support has been dropped as it is unmaintained.

	== Upgrading ==
	Several changes to the database have been made from 1.6:

	* A new "langlinks" table tracks interlanguage links
	* A new "filearchive" table stores information on deleted files
	* A new "querycache_info" table stores information on query page updates

	To ensure that these tables are filled with data, run refreshLinks.php after
	the upgrade.

	If you are upgrading from MediaWiki 1.4.x or earlier, some major database
	changes are made, and there is a slightly higher chance that things could
	break. Don't forget to always back up your database before upgrading!

	== Configuration changes ==

	Some configuration options have changed:
	* $wgAllowExternalImages now defaults to off for increased security.
	* $wgLocalTZoffset was in hours, it is now using minutes.
	* Extensions may register special pages via the $wgSpecialPages array without
	forcing an early load of the SpecialPage.php class file.

	== Major new features ==

	* Deleted files can now be archived and undeleted, if you set up an appropriate
	non-web-accessible directory. Set $wgSaveDeletedFiles on and an appropriate
	directory path in $wgFileStore['deleted']['directory']
	* Experimental PostgreSQL support has been updated. It may or may not be in
	usable shape; those interested in PostgreSQL are encouraged to follow 1.8
	development.

	=== Caveats ===
	Some output, particularly involving user-supplied inline HTML, may not
	produce 100% valid or well-formed XHTML output. Testers are welcome to
	set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
	cases, but this is not recommended on live sites. (This must be set for
	MathML to display properly in Mozilla.)

	= MediaWiki 1.6 =

	== MediaWiki 1.6.12 ==

	February 7, 2009

	This is a security update to the Spring 2006 quarterly release.

	A number of cross-site scripting (XSS) security vulnerabilities were discovered
	in the web-based installer (config/index.php). These vulnerabilities all
	require a live installer -- once the installer has been used to install a
	wiki, it is deactivated.

	Note that cross-site scripting vulnerabilities can be used to attack any
	website in the same cookie domain. So if you have an uninstalled copy of
	MediaWiki on the same site as an active web service, MediaWiki could be used to
	attack the active service.

	If you are hosting an old copy of MediaWiki that you have never installed, you
	are advised to remove it from the web.

	== MediaWiki 1.6.11 ==

	December 15, 2008

	This is a security update to the Spring 2006 quarterly release.

	David Remahl of Apple's Product Security team has identified a number of
	security issues in previous releases of MediaWiki. Subsequent analysis by the
	MediaWiki development team expanded the scope of these vulnerabilities. The
	issues with a significant impact are as follows:

	* An XSS vulnerability affecting Internet Explorer clients for all MediaWiki
	installations with uploads enabled. [CVE-2008-5250]
	* An XSS vulnerability affecting clients with SVG scripting capability (such as
	Firefox 1.5+), for all MediaWiki installations with SVG uploads enabled.
	[CVE-2008-5250]
	* A CSRF vulnerability affecting the Special:Import feature, for all MediaWiki
	installations since the feature was introduced in 1.3.0. [CVE-2008-5252]

	XSS (cross-site scripting) vulnerabilities allow an attacker to steal an
	authorised user's login session, and to act as that user on the wiki. The
	authorised user must visit a web page controlled by the attacker in order to
	activate the attack. Intranet wikis are vulnerable if the attacker can
	determine the intranet URL, even if the attacker cannot access it.

	CSRF vulnerabilities allow an attacker to act as an authorised user on the
	wiki, but unlike an XSS vulnerability, the attacker can only act as the user in
	a specific and restricted way. The present CSRF vulnerability allows pages to
	be edited, with forged revision histories. Like an XSS vulnerability, the
	authorised user must visit the malicious web page to activate the attack.

	Rather than backport our SVG validation code to this ancient branch, we have
	instead disabled SVG uploads. To enable SVG uploads, please upgrade to
	MediaWiki 1.13.3 or later.

	The other two issues have been fixed.

	== MediaWiki 1.6.10 ==

	February 20, 2007

	This is a security and bug-fix update to the Spring 2006 quarterly release.

	An XSS injection vulnerability based on Microsoft Internet Explorer's UTF-7
	charset autodetection was located in the AJAX support module, affecting MSIE
	users on MediaWiki 1.6.x and up when the optional setting $wgUseAjax is enabled.

	If you are using an extension based on the optional Ajax module, either disable
	it or upgrade to a version containing the fix:

	* 1.9: fixed in 1.9.3
	* 1.8: fixed in 1.8.4
	* 1.7: fixed in 1.7.3
	* 1.6: fixed in 1.6.10

	There is no known danger in the default configuration, with $wgUseAjax off.

	* ([[mediazilla:8819\|bug 8819]]) Fix full path disclosure with skins
	dependencies
	* Add 'charset' to Content-Type headers on various HTTP error responses to
	forestall additional UTF-7-autodetect XSS issues. PHP sends only 'text/html' by
	default when the script didn't specify more details, which some inconsiderate
	browsers consider a license to autodetect the deadly, hard-to-escape UTF-7.
	This fixes an issue with the Ajax interface error message on MSIE when
	$wgUseAjax is enabled (not default configuration); this UTF-7 variant on a
	previously fixed attack vector was discovered by Moshe BA from BugSec:
	http://www.bugsec.com/articles.php?Security=24
	* Trackback responses now specify XML content type

	== MediaWiki 1.6.9 ==

	January 9, 2007

	* ([[mediazilla:6621\|bug 6621]]) Backported German translation for
	'eauthentsent'

	* ([[mediazilla:6680\|bug 6680]]) Added localisation for Dutch bookstore list
	(nl)
	* ([[mediazilla:6730\|bug 6730]]) Clearer usage of message 'titlematch' in
	German translation (de)
	* XSS fix in AJAX module

	An XSS injection vulnerability was located in the AJAX support module,
	affecting MediaWiki 1.6.x and up when the optional setting $wgUseAjax is
	enabled.

	There is no danger in the default configuration, with $wgUseAjax off.

	If you are using an extension based on the optional AJAX module, either disable
	it or upgrade to a version containing the fix:

	* 1.9: fixed in 1.9.0rc2
	* 1.8: fixed in 1.8.3
	* 1.7: fixed in 1.7.2
	* 1.6: fixed in 1.6.9

	== MediaWiki 1.6.8 ==

	July 8, 2006

	MediaWiki 1.6.8 is a security and bugfix maintenance release of the Spring 2006
	snapshot:

	A potential HTML/JavaScript-injection vulnerability in a debugging script has
	been fixed. Only versions and configurations of PHP vulnerable to the $GLOBALS
	overwrite vulnerability are affected.

	As a workaround for existing installs, profileinfo.php may simply be deleted if
	it's not being used.

	* ([[mediazilla:5957\|bug 5957]]) Updates to Hebrew translation (he)
	* Respect language directionality when displaying arrow in
	Special:Brokenredirects
	* ([[mediazilla:6415\|bug 6415]]) Typo in Parser.php
	* Fixed potential XSS in profileinfo.php

	== MediaWiki 1.6.7 ==

	June 6, 2006

	MediaWiki 1.6.7 is a security and bugfix maintenance release of the Spring 2006
	snapshot:

	An HTML/JavaScript-injection vulnerability in the edit form has been closed.
	This vulnerability was new in 1.6.0; MediaWiki versions 1.5.x or earlier are
	not affected.

	Extensions, comments, and <nowiki><nowiki></nowiki> sections are now handled in
	a one-pass way which is more reliable and safer. Under earlier versions of
	MediaWiki, certain extensions could be abused to inject HTML/JavaScript into
	the page.

	Additional precautions are made against offsite form submissions when the
	restricted raw HTML mode is enabled.

	Some small localization and user interface updates are also included.

	*([[MediaZilla:6051\|bug 6051]]) Improvement to German localisation (de)
	*([[MediaZilla:6017\|bug 6017]]) Update bookstore list for German language (de)
	*([[MediaZilla:6138\|bug 6138]]) Minor grammar tweak in "loginreqlink"
	*([[MediaZilla:5957\|bug 5957]]) Update for Hebrew language (he)
	*Increase robustness of parser placeholders; fixes some glitches when adjacent
	to identifier-ish constructs such as URLs.
	*([[MediaZilla:5384\|bug 5384]]) Fix <nowiki><!-- comments --> in <ref></nowiki>
	extension
	*Nesting of different tag extensions and comments should now work more
	consistently and more safely. A cleaner, one-pass tag strip lets the 'outer'
	tag either take source (<nowiki><nowiki></nowiki>-style) or pass it down to
	further parsing (<nowiki><ref></nowiki>-style). There should no longer be
	surprise expansion of foreign extensions inside HTML output, or differences in
	behavior based on the order tags are loaded.
	*([[MediaZilla:885\|bug 885]]) Pre-save transform no longer silently appends
	close tags
	*Pre-save transform no longer changes the case of close tags
	*Edit security precautions in raw HTML mode, etc

	== MediaWiki 1.6.6 ==

	May 23, 2006

	MediaWiki 1.6.6 is a security and bugfix maintenance release.

	An XSS injection vector in brace replacement has been fixed, as have some
	potential problems with table parsing. Upgrading is strongly recommended for
	all users of 1.6. MediaWiki versions 1.5 and earlier are not affected.

	Additionally some localization and user interface updates are included.

	* Correct "revertpage" message in English
	* ([[MediaZilla:5507\|bug 5507]]) Logouttext now uses wiki markup
	* (bugs [[MediaZilla:5857\|5857]], [[MediaZilla:5957\|5957]]) Update for German
	localisation (de)
	* ([[MediaZilla:5586\|bug 5586]]) <nowiki><gallery></nowiki> treated text as
	links

	* ([[MediaZilla:6025\|bug 6025]]) SpecialImport: wrong message when no file
	selected
	* ([[MediaZilla:6015\|bug 6015]]) EditPage: add spacing in the boxes "edit is
	minor" and "watch this"
	* ([[MediaZilla:6018\|bug 6018]]) Userrights: new message when no user specified
	('nouserspecified')
	* ([[MediaZilla:6055\|bug 6055]]) Fix for HTML/JS injection bug in variable
	handler (found by Nick Jenkins)
	* Reordered wiki table handling and <nowiki>__TOC__</nowiki> extraction in the
	parser to better handle some overlapping tag cases.
	* Only the first <nowiki>__TOC__</nowiki> is now turned into a TOC.
	* ([[MediaZilla:361\|bug 361]]) URL in URL, they were almost fixed. Now they are.

	== MediaWiki 1.6.5 ==

	May 2, 2006

	* Rolled back the buggy patch for [[MediaZilla:5497\|bug 5497]].

	== MediaWiki 1.6.4 ==

	== MediaWiki 1.6.0 ==

	April 5, 2006

	MediaWiki is now using a "continuous integration" development model with
	quarterly snapshot releases. The latest development code is always kept "ready
	to run", and in fact runs our own sites on Wikipedia.

	Release branches will continue to receive security updates for about a year
	from first release, but nonessential bugfixes and feature development will take
	place on the development trunk and will appear in the next quarterly release.

	Those wishing to use the latest code instead of a branch release can [[Download
	from SVN\|obtain it from source control]].

	=== What's new in 1.6 ===

	'''User interface:'''
	* The account creation form has been separated from the user login form.
	* Page protection/unprotection uses a new, expanded form

	'''Templates:'''
	* Categories and "what links here" now update as expected when adding or
	removing links in a template.
	* Template parameters can now have default values, as <nowiki>{{{name\|default
	value}}}</nowiki>

	'''Uploads:'''
	* Optional support for rasterizing SVG images to PNG for inline display

	'''Feeds:'''
	* Feed generation upgraded to Atom 1.0
	* Diffs in RSS and Atom feeds are now colored for improved readability.

	'''Database:'''
	* MySQL 3.23.x support dropped; 4.0 or later required
	* Experimental support for Unicode mode of MySQL 4.1/5.0 (moderately tested)
	* Experimental Oracle support (not well tested!)

	'''Anti-spam extension support:'''
	* [[meta:SpamBlacklist extension\|SpamBlacklist extension]] now has support for
	automated cleanup.
	* Support for a [[meta:ConfirmEdit extension\|captcha extension]] to restrict
	automated spam edits.

	Numerous bug fixes and other behind-the-scenes changes have been made; see the
	file HISTORY for a complete change list.

	content loading and viewing, for clarity and consistency.
	* (bug 4104) 'OutputPageBeforeHTML' hook to postprocess article HTML on
	page view (comes after parser cache, if used). Patch by ThomasV.
	* Linker::formatComment corrupted the passed title object on PHP 5

	* Added wfDie() wrapper, and some manual die(-1), to force the return code
	to the shell to return nonzero when we crap out with an error.
	* Allow input of the stub from a compressed file instead of stdin
	for dumpTextPass.php; easier to get errors back on the shell
	* Added an attractive space on the namespace selector on contribs
	* Move PHP 5-friendly XHTML doctype hack to Sanitizer, use for sig checks.

	* Add cache-safe alternate sitenotice for anonymous users.
	(MediaWiki:Anonnotice) This is displayed instead of the regular sitenotice,
	if it exists. If not, the regular sitenotice shows. If that doesn't exist,
	the value of $wgSiteNotice is used, and if that's null, then nothing is shown.
	* Spit the generated LocalSettings code out during the installer as an aid
	to debugging issues. (Keep this?)
	* Use __FILE__ to form path in new LocalSettings.php, so it stays accurate
	when the directory is relocated for typical usage.

	* Do not tidy interface messages (unless full tidy is set)
	* Do not trust equality propagation and give more hints to MySQL

	than the per-page count for full-history dumps.
	* Include timestamp in wfDebugLog breakouts

	* (bug 4781) Output links with the percent-encoding they're supplied with;
	save the normalization for internal link storage. The normalization is a bit
	buggy and can make incorrect foldings in the query string and such, so isn't
	reliable beyond the hostname where it's used for the spam bulk checker.
	* Don't URL-decode in the title attribute for URL links; it can produce false

	== Compatibility ==

	Older PHP 4.2 and 4.1 releases are no longer supported; PHP 4 users must
	upgrade to 4.3 or later.

	MediaWiki 1.6 is the last major version to support PHP 4; future versions will
	require PHP 5.

	MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
	At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.

	== Upgrading ==

	Several changes to the database have been made from 1.5; these are relatively
	minor but do require that the update process be run before the new code will
	work properly:

	* A new "templatelinks" table tracks template inclusions.
	* A new "externallinks" table tracks URL links; this can be used by a mass
	spam-cleanup tool in the SpamBlacklist extension.
	* A new "jobs" table stores a queue of pages to update in the background; this
	is used to update links in including pages when templates are edited.

	To ensure that these tables are filled with data, run refreshLinks.php after
	the upgrade.

	If you are upgrading from MediaWiki 1.4.x or earlier, some major database
	changes are made, and there is a slightly higher chance that things could
	break. Don't forget to always back up your database before upgrading!

	=== Caveats ===

	Some output, particularly involving user-supplied inline HTML, may not produce
	100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType
	= "application/xhtml+xml"; to test for remaining problem cases, but this is not
	recommended on live sites. (This must be set for MathML to display properly in
	Mozilla.)


	= MediaWiki 1.5 =

	== MediaWiki 1.5.9 ==
	* (bug 3359) Add hooks on completion of file upload

	== MediaWiki 1.5.8 ==

	March 26, 2006

	MediaWiki 1.5.8 is a security and bugfix maintenance release.

	A bug in decoding of certain encoded links could allow injection of raw
	HTML into page output; this could potentially lead to XSS attacks.

	Some minor UI fixes were also made, see the change log at the bottom of
	this file.


	== MediaWiki 1.5.7 ==

	March 2, 2006

	MediaWiki 1.5.7 is a bugfix maintenance release.

	Most importantly, a security issue in the installer has been fixed. The bug
	affects new installations of 1.5.6 only. If the user specified the MySQL root
	password, to allow the installer to create an unprivileged account, the
	installer would not only create the new account but also change the root
	password to be equal to the password of the new account.

	Anyone affected by this bug will need to change the root password back
	manually. For information about how to change passwords in MySQL please see:
	http://dev.mysql.com/doc/refman/5.1/en/passwords.html

	This version includes fixes for compatibility with Internet Explorer 7
	beta 2, and various other bugs; see the full changelog at the end of
	the release notes.


	== MediaWiki 1.5.6 ==

	January 19, 2006

	MediaWiki 1.5.6 is a security and bugfix maintenance release.

	A bug in edit comment formatting could send PHP into an infinite loop
	if certain malformed links were included. In most installations, this
	would cause the script to fail after PHP's 30-second failsafe timeout.

	Some improvements have been made to the installer which should make
	installation possible on a system with a broken MySQL "root" account.

	For several other minor fixes, see the complete changelog at the end
	of this file.


	== MediaWiki 1.5.5 ==

	January 5, 2006

	MediaWiki 1.5.5 is a security and bugfix maintenance release.

	Detection for uploads of Windows Metafile (.wmf) images has been added
	to help protect against a client-side vulnerability in unpatched Microsoft
	Windows operating systems.

	Sites which have enabled uploads and added non-standard file types
	(such as .ogg, .doc, or .pdf) should upgrade to this release to ensure
	that malicious .wmf files can't be uploaded with a fake extension;
	such files could put visitors to the site at risk.

	For more details on this, see:
	https://en.wikipedia.org/wiki/Windows_Metafile_vulnerability

	Additionally, a maintenance script removeUnusedAccounts.php has been added;
	this replaces an older Perl script which had not been updated for the new
	schema in 1.5.


	== MediaWiki 1.5.4 ==

	December 21, 2005

	MediaWiki 1.5.4 is a security and bugfix maintenance release.

	A hardcoded internal placeholder string has been replaced with a random
	one. This closes a hole where security checks in inline style attributes
	could be bypassed, injecting JavaScript code that could execute in
	Microsoft Internet Explorer.

	Other browsers would not be vulnerable.

	Several minor fixes are included in this release, most notably a fix
	to clear the "you have new messages" flag properly for usernames
	containing spaces when e-mail notification is enabled.

	See the changelog at the end of the release notes for a full list of
	fixes.


	== MediaWiki 1.5.3 ==

	December 4, 2005

	MediaWiki 1.5.3 is a security and bugfix maintenance release.

	Validation of the user language option was broken by a code change in
	May 2005, opening the possibility of remote code execution as this
	parameter is used in forming a class name dynamically created with
	eval().

	The validation has been corrected in this version. All prior 1.5 release
	and prelease versions are affected; 1.4 and earlier and not affected.

	Additionally several bugs have been fixed; see the changelog later in
	this file for a complete list.


	== MediaWiki 1.5.2 ==

	November 2, 2005

	MediaWiki 1.5.2 is a bugfix maintenance release.

	A change in PHP 4.4.1 and PHP 5.1.0RC broke handling of extension and
	<pre> sections, causing garbage data to be inserted in output and saved
	edits. This version works around the change.

	Several other glitches with MySQL 5.0 and PHP 5.0.5 were also fixed;
	see the change log below for a complete list.


	== MediaWiki 1.5.1 ==

	October 26, 2005

	MediaWiki 1.5.1 is a bugfix and security maintenance release, and is a
	recommended upgrade for all installations.

	This release includes further corrections to the inline CSS style sanitation
	which works around a JavaScript "feature" on Microsoft Internet Explorer.
	Users of Microsoft Internet Explorer for Windows may be vulnerable to
	XSS injections on prior versions; users of standards-compliant browsers
	are not vulnerable.

	Major fixes include:
	* Image pages work again with resizing disabled
	* Works in MySQL 5.0 strict mode

	There is experimental support in this release for explicitly declaring
	the UTF-8 charset in the database; this has been tested with MySQL 5.0.15
	but should work on 4.1 as well.

	IMPORTANT: Changing this setting on an existing wiki may produce interesting
	data corruption, depending on server configuration. Page contents should,
	usually, be unaffected, but page titles and other items may be. Limitations
	in MySQL's Unicode support mean that characters outside the BMP cannot be used
	in page titles or various other fields when using this mode.

	Table definitions are in maintenance/mysql5/tables.sql, and the runtime
	option to send 'SET NAMES utf8' is set by $wgDBmysql5 = true.

	(MySQL 3.23.x and 4.0.x do not support character set declarations; on these
	versions MediaWiki simply works with UTF-8 data and MySQL is blissfully
	unaware of it.)



	== MediaWiki 1.5.0 final ==

	October 5, 2005

	MediaWiki 1.5.0 is the new stable release branch of MediaWiki, and is
	recommended for all new installations.

	Any wikis running a 1.5 beta or release candidate are strongly recommended
	to upgrade to the final release, which includes a number of bug fixes and
	a security fix for CSS bugs in Microsoft Internet Explorer.

	IMPORTANT: Running a 1.3 or 1.4 wiki and don't want to jump to 1.5 yet?
	Be sure to upgrade to 1.3.17 or 1.4.11, also released today. Versions
	prior to 1.3.16 and 1.4.10 have a serious data corruption bug which is
	triggered by a spambot known to operate in the wild.


	=== What's new in 1.5? ===

	Schema:
	The core table schema has changed significantly. This should make better
	use of the database's cache and disk I/O, and make significantly speed up
	rename and delete operations on pages with very long edit histories.

	Unfortunately this does mean upgrading a wiki of size from 1.4 will require
	some downtime for the schema restructuring, but future storage backend
	changes should be able to integrate into the new system more easily.

	Permalinks:
	The current revision of a page now has a permanent 'oldid' number assigned
	immediately, and the id numbers are now preserved across deletion/undeletion.
	A permanent reference to the current revision of a page is now just a matter
	of going to the 'history' tab and copying the first link in the list.

	Page move log:
	Renames of pages are now recorded in Special:Log and the page history.
	A handy revert link is available from the log for sysops.

	Editing diff:
	Ever lost track of what you'd done so far during an edit? A 'Show diff'
	button on the edit page now makes it easy to remember.

	Uploads:
	It's now possible to specify the final filename of an upload distinct
	from the original filename on your disk.

	An image link for a missing file will now take you straight to the upload
	page.

	More metadata is pre-extracted from uploaded images, which will ease pressure
	on disk or NFS volumes used to store images. EXIF metadata is displayed on
	the image description page if PHP is configured with the necessary module.

	If .svg files are added to the upload whitelist, you can choose to render
	them to rasterized .png images for inline display using one of several
	external helper programs. See DefaultSettings.php for SVG options.

	User accounts:
	There are some changes to the user permissions system, with assignable
	groups. Note that this does not allow you to make pages which are only
	accessible to certain groups.

	For details see: https://www.mediawiki.org/wiki/Manual:User_rights

	E-mail:
	User-to-user e-mail can now be restricted to require a mail-back confirmation
	first to reduce potential for abuse with false addresses.

	Updates to user talk pages and watchlist entries can optionally send e-mail
	notifications.

	External hooks:
	A somewhat experimental interface for hooking in an external editor
	application is included.

	And...
	A bunch of stuff we forgot to mention.


	=== What's gone? ===

	Latin-1:
	Wikis must now be encoded in Unicode UTF-8; this has been the default for
	some time, but some languages could optionally be installed in Latin-1 mode.
	This is no longer supported.

	You can check if your current wiki is in Latin-1 mode by using your browser's
	"view source"; look for a line like this:

	<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

	If it says charset=utf-8, you're ready. If it says charset=iso8859-1,
	you may need to convert your data. (English-language wikis avoiding
	any accented characters may be able to get away without conversion.)

	MySQL 3.x:
	Some optimization hacks for MySQL 3.x have been removed as part of the schema
	clean-up (specifically, the inverse_timestamp fields).

	MediaWiki 1.5 may still run on 3.x, but wikis of non-trivial size should
	very seriously consider upgrading to a more modern release. MySQL 3.x support
	will probably be entirely dropped in the next major release.

	Special:Maintenance
	These tools were, ironically enough, not really maintained. This special
	page has been removed; insofar as some of its pieces were useful and haven't
	already been supplanted by other special pages they should be rewritten in
	an efficient and safe manner in the future.


	=== Caveats ===

	Upgrade:
	Wikis in Latin-1 encoding are no longer supported; only Unicode UTF-8.
	A new option $wgLegacyEncoding is provided to allow on-the-fly recoding of
	old page text entries, but other metadata fields (titles, comments etc) need
	to be pre-converted. The standard upgrade process does not yet fully automate
	this, but you can try the alternate partial-upgrader in upgrade1_5.php.

	The upgrade from 1.4 to 1.5 schema has not been tested for all cases, so
	it's possible you may experience problems in some combinations.

	Backups:
	The text entries of deleted pages are no longer removed from the main
	text table on deletion. If you provide public backup dumps of your databases,
	you will probably want to use the new XML-format dump generator, available
	as maintenance/dumpBackup.php.

	For more information on how we run our own public data dumps at Wikimedia,
	see http://meta.wikimedia.org/wiki/Data_dumps

	PostgreSQL:
	The table definitions for PostgreSQL install are out of date. PostgreSQL
	support may return in later releases, pending appropriate patches.

	MySQL 4.1+:
	Some users may encounter installation problems with MySQL 4.1 or higher
	due to strange charset encoding / collation configurations. Try setting
	to 'latin1' or 'utf8' if you encounter problems.



	== MediaWiki 1.5 release candidate 4 ==

	August 29, 2005

	MediaWiki 1.5rc4 is a preview release of the new 1.5 release series.
	It fixes compatibility with PHP 5.1, and corrects two cross-site scripting
	security bugs:

	* <math> tags were handled incorrectly when TeX rendering support is off,
	as in the default configuration.
	* Extension or <nowiki> sections in Wiki table syntax could bypass HTML
	style attribute restrictions for cross-site scripting attacks against
	Microsoft Internet Explorer

	Wikis where the optional math support has been enabled are not vulnerable
	to the first, but are vulnerable to the second.



	== MediaWiki 1.5 release candidate 3 ==

	August 24, 2005

	MediaWiki 1.5rc3 is a preview release of the new 1.5 release series.
	It fixes several major problems in 1.5rc2:

	* Fixed a cross-site scripting injection in the search form
	(broken since 1.5beta1)

	* Fixed upgrades from 1.4 database schema
	(broken since 1.5rc2)

	1.3 and 1.4 releases are not vulnerable to the XSS bug, but anyone
	running an earlier 1.5 beta or release candidate should upgrade
	immediately.


	== MediaWiki 1.5 release candidate 2 ==

	August 23, 2005

	MediaWiki 1.5rc2 is a preview release of the new 1.5 release series.
	Numerous bug fixes since last beta, plus a security fix; see change
	log below for full details.

	A flaw in the interaction between extensions and HTML attribute
	sanitization was discovered which could allow unauthorized use
	of offsite resources in style sheets, and possible exploitation
	of a JavaScript injection feature on Microsoft Internet Explorer.

	This version expands the returned text and properly checks it
	before output.

	A 1.5rc1 release was mistakenly made from the incorrect source code
	branch; 1.5rc2 is identical to the actual 1.5rc1 in revision control
	except for version number.


	== MediaWiki 1.5 beta 4 ==

	July 30, 2005

	MediaWiki 1.5 beta 4 is a preview release of the new 1.5 release series.
	A number of bugs have been fixed since beta 3; see the full changelist below.


	== MediaWiki 1.5 beta 3 ==

	July 7, 2005

	MediaWiki 1.5 beta 3 is a preview release of the new 1.5 release
	series, with a security update over beta 2.

	Incorrect escaping of a parameter in the page move template could
	be used to inject JavaScript code by getting a victim to visit a
	maliciously constructed URL. Users of vulnerable releases are
	recommended to upgrade to this release.

	Vulnerable versions:
	* 1.5 preview series: n <= 1.5beta2 vulnerable, fixed in 1.5beta3
	* 1.4 stable series: 1.4beta6 <= n <= 1.4.5 vulnerable, fixed in 1.4.6
	* 1.3 legacy series: not vulnerable

	This release also includes several bug fixes and localization updates.
	See the changelog at the end of this file for a detailed list.



	== MediaWiki 1.5 beta 2 ==

	July 5, 2005

	MediaWiki 1.5 beta 2 is a preview release of the new 1.5 release series.
	While most exciting new bugs should have been ironed out at this point,
	third-party wiki operators should probably not run this beta release
	on a public site without closely following additional development.

	Anyone who _has_ been running beta 1 is very very strongly advised to
	upgrade to beta 2, as it fixes many bugs from the previous beta including
	a couple of HTML and SQL injections.

	This release should be followed by one or two release candidates and
	a 1.5.0 final within the next few weeks.

	Beta upgraders, note there are some minor database changes. For upgrades
	from 1.4, see the file UPGRADE for details on significant database and
	configuration file changes.

	Beta 2 includes a preliminary command-line XML wiki dump importer tool,
	maintenance/importDump.php, paired with maintenance/dumpBackup.php.
	These use the same format as Special:Export and Special:Import, able
	to package a wiki's entire page set independent of the backend database
	and compression format.


	== MediaWiki 1.5 beta 1 ==

	June 26, 2005

	MediaWiki 1.5 beta 1 is a preview release, pretty much feature complete,
	of the new 1.5 release series. There are several known and likely a number
	of unknown bugs; it is not recommended to use this release in a production
	environment but would be recommended for testing in mind of an upcoming
	deployment.

	A number of significant changes have been made since the alpha releases,
	including database changes and a reworking of the user permissions settings.
	See the file UPGRADE for details of upgrading and changing your prior
	configuration settings for the new system.



	== MediaWiki 1.5 alpha 2 ==

	June 3, 2005

	MediaWiki 1.5 alpha 2 includes a lot of bug fixes, feature merges,
	and a security update.

	Incorrect handling of page template inclusions made it possible to
	inject JavaScript code into HTML attributes, which could lead to
	cross-site scripting attacks on a publicly editable wiki.

	Vulnerable releases and fix:
	* 1.5 prerelease: fixed in 1.5alpha2
	* 1.4 stable series: fixed in 1.4.5
	* 1.3 legacy series: fixed in 1.3.13
	* 1.2 series no longer supported; upgrade to 1.4.5 strongly recommended


	== MediaWiki 1.5 alpha 1 ==

	May 3, 2005

	This is a testing preview release, being put out mainly to aid testers in
	finding installation bugs and other major problems. It is strongly recommended
	NOT to run a live production web site on this alpha release.

	WARNING: USE OF THIS ALPHA RELEASE MAY INFEST YOUR HOUSE WITH
	TERMITES, ROT YOUR TEETH, GROW HAIR ON YOUR PALMS, AND PASTE
	INNUENDO INTO YOUR C.V. RIGHT BEFORE A JOB INTERVIEW!
	DON'T SAY WE DIDN'T WARN YOU, MAN. WE TOTALLY DID RIGHT HERE.

	produce 100% valid or well-formed XHTML output. Testers are welcome to
	set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
	cases, but this is not recommended on live sites. (This must be set for
	MathML to display properly in Mozilla.)

	= MediaWiki 1.4 =

	== MediaWiki 1.4.15 ==

	(released March 26, 2006) MediaWiki 1.4.15 is a security maintenance release. A
	bug in decoding of certain encoded links could allow injection of raw HTML into
	page output; this could potentially lead to XSS attacks. Additionally, this
	release may display more correctly in IE7 betas.

	== MediaWiki 1.4.14 ==
	(released January 19, 2006) MediaWiki 1.4.14 is a security and bugfix
	maintenance release. A bug in edit comment formatting could send PHP into an
	infinite loop if certain malformed links were included. In most installations,
	this would cause the script to fail after PHP's 30-second failsafe timeout. For
	several other minor fixes, see the complete changelog at the end of this file.

	== MediaWiki 1.4.13 ==
	(released January 5, 2006) MediaWiki 1.4.13 is a security maintenance
	release.Detection for uploads of Windows Metafile (.wmf) images has been added
	to help protect against a client-side vulnerability in unpatched Microsoft
	Windows operating systems. Sites which have enabled uploads and added
	non-standard file types (such as .ogg, .doc, or .pdf) should upgrade to this
	release to ensure that malicious .wmf files can't be uploaded with a fake
	extension; such files could put visitors to the site at risk. For more details
	on this, see: https://en.wikipedia.org/wiki/Windows_Metafile_vulnerability

	== MediaWiki 1.4.12 ==
	(released 2005-11-02) MediaWiki 1.4.12 is a bugfix and security maintenance
	release. A change in PHP 4.4.1 broke handling of extension and
	<nowiki><pre></nowiki> sections, causing garbage data to be inserted in output
	and saved edits. This version works around the change. This release includes
	further corrections to the inline CSS style sanitation which works around a
	JavaScript "feature" on Microsoft Internet Explorer. Users of Microsoft
	Internet Explorer for Windows may be vulnerable to XSS injections on prior 1.4
	releases; users of standards-compliant browsers are not vulnerable.

	== MediaWiki 1.4.11 ==
	(released 2005-10-05) MediaWiki 1.4.11 is a security maintenance release.
	Unsafe handling of CSS by Microsoft Internet Explorer could be exploited to
	produce cross-site scripting attacks by JavaScript injection to clients running
	that browser. This release blacklists several additional variants from use in
	HTML inline style attributes. All publicly accessible wikis are recommended to
	upgrade to reduce the risk to visitors using Microsoft web browsers. Note: the
	MediaWiki 1.4.x series is not compatible with PHP 5.0.5 or higher. Upgrade to
	the 1.5.0 release if you require this version of PHP 5.

	== MediaWiki 1.4.10 ==
	(released 2005-09-21) MediaWiki 1.4.10 is a security maintenance release. A bug
	in edit submission handling could cause corruption of the previous revision in
	the database if an abnormal URL was used, such as those used by some spambots.
	Affected releases:
	* 1.4.x <= 1.4.9; fixed in 1.4.10
	* 1.3.x <= 1.3.15; fixed in 1.3.16
	1.5 release candidates are not affected by this problem. All publicly editable
	wikis are strongly recommended to upgrade immediately.
	1.4 releases can be manually patched by changing this bit in EditPage.php:

	<syntaxhighlight lang="php">
	function importFormData( &$request ) {
	if( $request->wasPosted() ) {
	</syntaxhighlight>
	to:
	<syntaxhighlight lang="php">
	function importFormData( &$request ) {
	if( $request->getVal( 'action' ) == 'submit' && $request->wasPosted() )
	{
	</syntaxhighlight>
	== MediaWiki 1.4.9 ==
	(released 2005-08-29) MediaWiki 1.4.9 is a security maintenance release. It
	corrects two cross-site scripting security bugs:
	* <nowiki><math></nowiki> tags were handled incorrectly when TeX rendering
	support is off, as in the default configuration.
	* Extension or <nowiki><nowiki></nowiki> sections in Wiki table syntax could
	bypass HTML style attribute restrictions for cross-site scripting attacks
	against Microsoft Internet Explorer Wikis where the optional math support has
	been enabled are not vulnerable to the first, but are vulnerable to the
	second.

	== MediaWiki 1.4.8 ==
	(released 2005-08-23) MediaWiki 1.4.8 is a bug fix and security maintenance
	release. A flaw in the interaction between extensions and HTML attribute
	sanitization was discovered which could allow unauthorized use of offsite
	resources in style sheets, and possible exploitation of a JavaScript injection
	feature on Microsoft Internet Explorer. This version expands the returned text
	and properly checks it before output. Additionally, an update to
	skins/MonoBook.php ensures that sites using the default MonoBook skin will
	display correctly in the Internet Explorer 7 beta. (1.3 and 1.5 are not
	affected by this bug.)

	== MediaWiki 1.4.7 ==
	(released 2005-07-16)
	MediaWiki 1.4.7 is a bug fix release. Those affected by the following problems
	in 1.4.6 should upgrade:
	* Watchlist breakage on MySQL 3.23.x and with table prefix enabled
	* Possible breakage in watchlist, some image resizing modes on PHP 4.1.2 1.4.6
	included a fix for a cross-site scripting vulnerability, so anyone running
	older 1.4 releases is very strongly encouraged to upgrade as well. Note to
	upgraders: this version of MediaWiki is known to produce a large number of
	notice-level warnings under the newly released PHP 4.4.0. These appear however
	to be harmless; if you encounter them add this to your LocalSettings.php to
	suppress the notices: error_reporting( E_ALL & ~E_NOTICE ); PHP 5.1.0beta3 is
	known to be incompatible at this time.

	== MediaWiki 1.4.6 ==
	(released 2005-07-07) MediaWiki 1.4.6 is a bug fix and security update release.
	Incorrect escaping of a parameter in the page move template could
	be used to inject JavaScript code by getting a victim to visit a maliciously
	constructed URL. Users of vulnerable releases are recommended to upgrade to
	this release. Vulnerable versions:
	* 1.5 preview series: n <= 1.5beta2 vulnerable, fixed in 1.5beta3
	* 1.4 stable series: 1.4beta6 <= n <= 1.4.5 vulnerable, fixed in 1.4.6
	* 1.3 legacy series: not vulnerable This release also includes fixes for some
	rare bug annoying HTTP errors, a PHP 4.1.2 breakage bug, and works around some
	template limitations introduced in 1.4.5. See the changelog at the end of this
	file for a detailed list of bugs fixed.

	== MediaWiki 1.4.5 ==
	(released 2005-06-03) MediaWiki 1.4.5 is a security update and bugfix release.
	Incorrect handling of page template inclusions made it possible to inject
	JavaScript code into HTML attributes, which could lead to cross-site scripting
	attacks on a publicly editable wiki. Vulnerable releases and fix:
	* 1.5 prerelease: fixed in 1.5alpha2
	* 1.4 stable series: fixed in 1.4.5
	* 1.3 legacy series: fixed in 1.3.13
	* 1.2 series no longer supported; upgrade to 1.4.5 strongly recommended This
	release also includes a number of bug fixes (see changelog below) and merges
	some large-server load balancing patches from Wikipedia. An experimental rate
	limiter for page edits and moves can be enabled with global, per-IP,
	per-subnet, or per-user bases. See configuration options in
	includes/DefaultSettings.php

	== MediaWiki 1.4.4 ==
	(released 2005-05-04) MediaWiki 1.4.4 is a bugfix release for the 1.4 stable
	release series. Some bugs in the installer/updater and refreshLinks maintenance
	script were introduced in the last release and have been corrected.

	== MediaWiki 1.4.3 ==

	(released 2005-04-28)

	MediaWiki 1.4.3 is a bugfix release for the 1.4 stable release series.

	Chiefly, this fixes a compatibility problem with PHP 5 and a minor link
	table corruption bug on initial page save.


	== MediaWiki 1.4.2 ==

	(released 2005-04-20)

	MediaWiki 1.4.2 is a security and bug fix release for the 1.4 stable release
	series.

	A cross-site scripting injection vulnerability was discovered, which
	affects only MSIE clients and is only open if MediaWiki has been
	manually configured to run output through HTML Tidy ($wgUseTidy).

	Several other bugs are fixed in this release, see the changelog below.

	All new installations are highly recommended to use 1.4.2 instead of
	1.3.x; 1.3.x users should consider upgrading for bug fixes and new
	features. Ealier 1.4.x release and beta users should upgrade to this
	release for relevant bug fixes; see the changelog later in this file.


	If you have trouble, remember to read this whole file and the online FAQ page
	before asking for help:

	https://www.mediawiki.org/wiki/Manual:FAQ


	=== READ THIS FIRST: Upgrading ===

	If upgrading from an older release, see the notes in the file UPGRADE.
	There are a couple of minor database changes from the beta releases,
	and somewhat larger changes from 1.3.x.

	Upgrading from a previous 1.4.x stable release installation should
	generally only require copying the new files over the old ones.


	==== READ THIS FIRST, TOO: MySQL 4.1 AND 5.0 ====

	MySQL 5.0 is a beta release, not yet ready for production use. If you
	are using it, the notes below about 4.1 apply to you too.

	If you have the choice of MySQL 4.0 or MySQL 4.1 and don't need 4.1 for
	some other application, you should consider sticking with 4.0 for the
	moment. 4.1 may require you to do extra fiddling to get things to work
	due to changes that aren't fully backwards-compatible.

	MySQL 4.1 has changed the authentication protocol in an incompatible
	way; many PHP installations still use the older client libraries and
	CANNOT CONNECT TO THE SERVER WITH A PASSWORD without some changes.

	See: http://dev.mysql.com/doc/mysql/en/Old_client.html

	If MySQL is set with utf-8 as the default character set, installation
	may fail with "key too long" errors. Set the default charset to 'latin1'
	for installation and it should work.

	The mysqldump backup generator now applies an automatic conversion to
	UTF-8, which may irretrivably corrupt your data. Pass the -charset option
	with the original default charset (eg 'latin1') to skip the conversion.


	==== READ THIS FIRST IF RUNNING ON A WINDOWS SERVER ====

	MediaWiki is tested and deployed primarily under the Apache web server
	on Linux Unix systems. There are known to be problems running on
	Microsoft's IIS which are not fully resolved. If you have a choice,
	try running under Apache on Windows, or on a Unix/Linux box instead.

	If you're having trouble with blank pages on IIS and can't switch,
	try the workaround suggested in this bug report:
	http://bugzilla.wikimedia.org/show_bug.cgi?id=1763


	=== New features ===

	* 'Recentchanges Patrol' to mark new edits that haven't yet been viewed.
	* New, searchable deletion/upload/protection logs
	* Image gallery generation (Special:Newimages and <gallery> tag)
	* SVG rasterization support (requires external support tools)
	* Users can select from the available localizations to override the
	default user interface language.
	* Traditional/Simplified Chinese conversion support
	* rel="nofollow" support to combat linkspam

	The current implementation adds this attribute to _all_ external URL
	links in wiki text (but not internal [[wiki links]] or interwiki links).
	To disable the attribute for _all_ external links, add this line to your
	LocalSettings.php:

	$wgNoFollowLinks = false

	For background information on nofollow see:

	http://www.google.com/googleblog/2005/01/preventing-comment-spam.html


	=== Installation and compatibility ===

	* The default MonoBook theme now works with PHP 5.0
	* Installation on systems with PHP's safe mode or other oddities
	should work more reliably, as MonoBook no longer needs to
	create a compiled template file for the wiki to run.
	* A table prefix may be specified, to avoid conflicts with other
	web applications forced to share a database.
	* More thorough UTF-8 input validation; fixes non-ASCII uploaded
	filenames from Safari.
	* Command-line database upgrade script.


	=== Customizability ===

	* Default user options can now be overridden in LocalSettings.
	* Skins system more modular: templates and CSS are now in /skins/
	New skins can be dropped into this directory and used immediately.
	* More extension hooks have been added.
	* Authentication plugin hook.
	* More internal code documentation, generated with phpdoc:
	https://doc.wikimedia.org/mediawiki-core/master/php/html/


	=== Optimization ===

	* For many operations, MediaWiki 1.4 should run faster and use
	less memory than MediaWiki 1.3. Page rendering is up to twice
	as fast. (Use a PHP accelerator such as Turck MMCache for best
	results with any PHP application, though!)
	* The parser cache no longer requires memcached, and is enabled
	by default. This avoids a lot of re-rendering of pages that
	have been shown recently, greatly speeding longer page views.
	* Support for compiled PHP modules to speed up page diff and
	Unicode validation/normalization. (Requires ability to compile
	and load PHP extensions).


	=== What isn't ready yet ===

	* A new user/groups permissions scheme has been held back to 1.5.
	* An experimental SOAP interface will be made available as an extension
	* PostgreSQL support is largely working, minus search and the installer.
	You can perform a manual installation.
	* E-mail notification of watched page changes and verification of
	user-submitted e-mail addresses is not yet included.
	* Log pages are not automatically imported into the new log table
	at upgrade time. A script to import old text log entries is
	incomplete, but may be available in later point releases.
	* Some localizations are still incomplete.



	== Changelog ==

	=== Important security updates ===

	A security audit found and fixed a number of problems. Users of MediaWiki
	1.3.10 and earlier should upgrade to 1.3.11; users of 1.4 beta releases
	prior to 1.4rc1 should upgrade immediately.

	==== Cross-site scripting vulnerability ====

	XSS injection points can be used to hijack session and authentication
	cookies as well as more serious attacks.

	* Media: links output raw text into an attribute value, potentially
	abusable for JavaScript injection. This has been corrected.
	* Additional checks added to file upload to protect against MSIE and
	Safari MIME-type autodetection bugs.

	As of 1.3.10/1.4beta6, per-user customized CSS and JavaScript is disabled
	by default as a general precaution. Sites which want this ability may set
	$wgAllowUserCss and $wgAllowUserJs in LocalSettings.php.


	==== Cross-site request forgery ====

	An attacker could use JavaScript-submitted forms to perform various
	restricted actions by tricking an authenticated user into visiting
	a malicious web page. A fix for page editing in 1.3.10/1.4beta6 has
	been expanded in this release to other forms and functions.

	Authors of bot tools may need to update their code to include the
	additional fields.


	==== Directory traversal ====

	An unchecked parameter in image deletion could allow an authenticated
	administrator to delete arbitrary files in directories writable by the
	web server, and confirm existence of files not deletable.


	==== Older issues ====

	Note that 1.4 beta releases prior to beta 5 include an input validation
	error which could lead to execution of arbitrary PHP code on the server.
	Users of older betas should upgrade immediately to the current version.


	Beta 6 also introduces the use of rel="nofollow" attributes on external
	links in wiki pages to reduce the effectiveness of wiki spam. This will
	cause participating search engines to ignore external URL links from wiki
	pages for purposes of page relevancy ranking.

	* (bug 1163) Special:Undelete showed oldest revision instead of newest
	* (bug 1938) Fix escaping of illegal character references in link text
	* (bug 1997) Fix for error on display of renamed items in Recentchanges on PHP5
	* (bug 1949) Profiling typo in rare error case
	* (bug 1963) Fix deletion log link when $wgCapitalLinks is off
	* (bug 1970) Don't show move tab for immobile pages
	* (bug 1770) Page creation recorded links from the 'newarticletext' message
	* Optional change to the site_stats table. When applied, this removes the need
	for expensive queries in Special:Statistics.


	=== 1.4.4 fixes ===

	* (bug 725) Let dir="ltr" attribute work again in MonoBook on RTL languages
	* (bug 2024) Skip JavaScript error for custom skins where .js message not set
	* (bug 2025) Updated Indonesian localization
	* (bug 2039) Updated Lithuanian localization


	=== Caveats ===

	Some output, particularly involving user-supplied inline HTML, may not
	produce 100% valid or well-formed XHTML output. Testers are welcome to
	set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
	cases, but this is not recommended on live sites. (This must be set for
	MathML to display properly in Mozilla.)

	=MediaWiki 1.3=

	== MediaWiki 1.3.18 ==
	(released 2005-11-02)
	MediaWiki 1.3.18 is a bugfix and security maintenance release. A change in PHP
	4.4.1 broke handling of extension and <nowiki><pre></nowiki> sections, causing
	garbage data to be inserted in output and saved edits. This version works
	around the change. This release includes further corrections to the inline CSS
	style sanitation which works around a JavaScript "feature" on Microsoft
	Internet Explorer. Users of Microsoft Internet Explorer for Windows may be
	vulnerable to XSS injections on prior 1.3 releases; users of
	standards-compliant browsers are not vulnerable.

	== MediaWiki 1.3.17 ==
	(released 2005-10-05)
	MediaWiki 1.3.17 is a security maintenance release. Unsafe handling of CSS by
	Microsoft Internet Explorer could be exploited to produce cross-site scripting
	attacks by JavaScript injection to clients running that browser. This release
	blacklists several additional variants from use in HTML inline style
	attributes. All publicly accessible wikis are recommended to upgrade to reduce
	the risk to visitors using Microsoft web browsers.Note: the MediaWiki 1.3.x
	series is not compatible with PHP 5.0.5 or higher. Upgrade to the 1.5.0 release
	if you require this version of PHP 5.

	== MediaWiki 1.3.16 ==
	(released 2005-09-21)
	MediaWiki 1.3.16 is a security maintenance release. A bug in edit submission
	handling could cause corruption of the previous revision in the database if an
	abnormal URL was used, such as those used by some spambots. Affected releases:
	* 1.4.x <= 1.4.9; fixed in 1.4.10
	* 1.3.x <= 1.3.15; fixed in 1.3.16
	1.5 release candidates are not affected by this problem. All publicly editable
	wikis are strongly recommended to upgrade immediately.
	1.3 releases can be manually patched by changing this bit in
	{{manual\|EditPage.php}}:
	<syntaxhighlight lang="php">
	if( $this->tokenOk( $request ) ) {
	$this->save = $request->wasPosted() && !$this->preview;
	} else {
	</syntaxhighlight>
	to:
	<syntaxhighlight lang="php">
	if( $this->tokenOk( $request ) ) {
	$this->save = $request->getVal( 'action' ) == 'submit' &&
	$request->wasPosted() && !$this->preview;
	} else {
	</syntaxhighlight>

	== MediaWiki 1.3.15, 2005-08-29 ==
	MediaWiki 1.3.15 is a security maintenance release. It corrects across-site
	scripting security bug:
	* <nowiki><math></nowiki> tags were handled incorrectly when TeX rendering
	support is off, as in the default configuration. Wikis where the optional math
	support has been enabled are not vulnerable. The 1.3.x series is no longer
	maintained except for security fixes; new users and those seeking bug fixes
	should upgrade to 1.4.9 or 1.5.0.

	== MediaWiki 1.3.14, 2005-08-23 ==
	MediaWiki 1.3.14 is a security maintenance release. A flaw in the interaction
	between extensions and HTML attribute sanitization was discovered which could
	allow unauthorized use of offsite resources in style sheets, and possible
	exploitation of a JavaScript injection feature on Microsoft Internet Explorer.
	The 1.3.x series is no longer maintained except for security fixes; new users
	and those seeking bug fixes should upgrade to 1.4.8 or 1.5.0. Existing 1.3.x
	installations not willing to upgrade to the current stable release should apply
	the change manually:
	In includes/Parser.php, function {{code\|inline=y\|lang=php\|fixTagAttributes()}}
	add:
	<syntaxhighlight lang="php">
	# Any placeholder items should have been unstripped already before
	# we got to this point. Raw text inserted later could be dangerous.
	if( strpos( $t, UNIQ_PREFIX ) !== false ) {
	wfDebug( "Parser::fixTagAttributes found stripped data placeholder;
	dropping attributes\n" );
	$t = '';
	}
	</syntaxhighlight>
	If you are actively using extensions to generate HTML attribute values, upgrade
	to 1.4 or 1.5 for a more thorough fix.

	== MediaWiki 1.3.13, 2005-06-03 ==
	MediaWiki 1.3.13 is a security maintenance release. Incorrect handling of page
	template inclusions made it possible to inject JavaScript code into HTML
	attributes, which could lead to cross-site scripting attacks on a publicly
	editable wiki. Vulnerable releases and fix:
	* 1.5 prerelease: fixed in 1.5alpha2
	* 1.4 stable series: fixed in 1.4.5
	* 1.3 legacy series: fixed in 1.3.13
	* 1.2 series no longer supported; upgrade to 1.4.5 strongly recommended The
	1.3.x series is no longer maintained except for security fixes; new users and
	those seeking general bug fixes should install 1.4.5. Existing 1.3.x
	installations not willing or able to upgrade to the current stable relase
	should update the installation to 1.3.13; only includes/Parser.php has changed
	from 1.3.12.

	== MediaWiki 1.3.12, 2005-02-20 ==
	MediaWiki 1.3.12 is a security maintenance release. A cross-site scripting
	injection vulnerability was discovered, which affects only MSIE clients and is
	only open if MediaWiki has been manually configured to run output through HTML
	Tidy ($wgUseTidy). The 1.3.x series is no longer maintained except for security
	fixes; new users and those seeking bug fixes should upgrade to 1.4.2. Existing
	1.3.x installations using Tidy not willing to upgrade to the current stable
	relase should either turn off Tidy or update the installation to 1.3.12.

	== MediaWiki 1.3.11, 2005-02-20 ==
	MediaWiki 1.3.11 is a security release.
	A security audit found and fixed a number of problems. Users of MediaWiki
	1.3.10 and earlier should upgrade to 1.3.11; users of 1.4 beta releases should
	upgrade to 1.4rc1.

	=== Cross-site scripting vulnerability ===
	XSS injection points can be used to hijack session and authentication cookies
	as well as more serious attacks.
	* Media: links output raw text into an attribute value, potentially abusable
	for JavaScript injection. This has been corrected.
	* Additional checks added to file upload to protect against MSIE and Safari
	MIME-type autodetection bugs.
	As of <code>1.3.10/1.4beta6</code>, per-user customized CSS and JavaScript is
	disabled by default as a general precaution. Sites which want this ability may
	set {{wg\|AllowUserCss}} and {{wg\|AllowUserJs}} in LocalSettings.php.

	=== Cross-site request forgery ===
	An attacker could use JavaScript-submitted forms to perform various restricted
	actions by tricking an authenticated user into visiting a malicious web page. A
	fix for page editing in 1.3.10/1.4beta6 has been expanded in this release to
	other forms and functions. Authors of bot tools may need to update their code
	to include the additional fields.

	=== Directory traversal ===
	An unchecked parameter in image deletion could allow an authenticated
	administrator to delete arbitrary files in directories writable by the web
	server, and confirm existence of files not deletable.

	== MediaWiki 1.3.10, 2005-02-03 ==
	MediaWiki 1.3.10 is a security release.
	An attacker could craft a URL which, when visited by a particular logged-in
	user, would execute arbitrary JavaScript code on the user's browser in the
	wiki's site context. This attack has been blocked, and as an extra precaution
	the user CSS and JavaScript subpage support is now disabled by default. Sites
	which want this ability may set {{wg\|AllowUserCss}} and {{wg\|AllowUserJs}} in
	{{manual\|LocalSettings.php}}. Additional protections have been added against
	off-site form submissions
	hijacking user credentials. Authors of bot tools may need to update their code
	to include additional fields. All wikis running 1.3.x are strongly urged to
	upgrade to 1.3.10.
	Changes from 1.3.9:
	* Logged-in edits and preview of user CSS/JS are now locked to a session token.
	* Per-user CSS and JavaScript subpage customizations now disabled by default.
	They can be re-enabled via {{wg\|AllowUserJs}} and {{wg\|AllowUserCss}}.
	* Removed .ogg from the default uploads whitelist as an extra precaution. If
	your web server is configured to serve Ogg files with the correct Content-Type
	header, you can re-add it in LocalSettings.php: {{wg\|FileExtensions}}<code>[] =
	'ogg'</code>

	== MediaWiki 1.3.9, 2004-12-12 ==
	MediaWiki 1.3.9 is a security and bug fix release.
	A flaw in upload handling has been found which may allow upload and execution
	of arbitrary scripts with the permissions of the web server. Only wikis that
	have enabled uploads and have a vulnerable Apache configuration will be
	affected, but to be safe all wikis should upgrade. Wikis with uploads available
	should either disable uploads or upgrade to 1.3.9 immediately; if other files
	are customized and require merging changes,
	includes/{{manual\|SpecialUpload.php}} may be replaced individually to add the
	fix. (It is also recommended to configure your web server to disable script
	execution in the 'images' subdirectory where uploads are placed, which prevents
	most attacks even if the wiki fails.)
	Changes from 1.3.8:
	* Backported "Templates used in this page"-feature of EditPage
	* Allow "MySkin" as a default skin.
	* ({{bugzilla\|938}}) Parse namespaces correctly on self-interwiki links
	* ({{bugzilla\|1010}}) fix broken Commons image link on [[Skin:Classic\|Classic]]
	& [[Skin:Cologne Blue\|Cologne Blue]]
	* ({{bugzilla\|1004}}) Norsk language names for interwiki links changed, Nauruan
	language name changed
	* Enhance upload extension blacklist to protect against vulnerable Apache
	configurations

	== MediaWiki 1.3.8, 2004-11-15 ==
	MediaWiki 1.3.8 is a bugfix release. Those running wikis with uploads enabled
	are strongly recommended to upgrade as this fixes several problems with
	overwriting previously-uploaded files.
	Changes from 1.3.7:
	* ({{bugzilla\|506}}) fix {{code\|inline=y\|lang=html\|array_key_exists()}} warning
	for IIS servers using ISAPI mode
	* ({{bugzilla\|718}}) fix bad charset in (file) cached pages
	* use local numerals in category page (for Hindi et al)
	* alias month abbreviations to month names in Hindi
	* add localized numerals for Gujarati and Kannada
	* fix Category and project namespaces for Hindi
	* Don't output bogus timestamp on [[Special:RecentChanges]] if no entries
	* Correct template include path which broke some but not all Windows installs
	* Fix edit form submission problem with some PHP versions
	* Disallow unreachable titles with %XX hex codes
	* Allow page [[0]] to be renamed
	* ({{bugzilla\|774}}) when saving with <code>section=new</code>, return to the
	anchor as with existing numbered section edits
	* Experimental shared upload overlay area (disabled by default)
	* ({{bugzilla\|806}}) Removed some "Wikipedia" hardcoding in German localization
	* User option localization fix for some extensions
	* ({{bugzilla\|809}}) now try to load the mysql php extension if it isn't loaded
	* ({{bugzilla\|848}}) fix error message in [[Special:Newpages]] RSS and Atom
	feeds
	* ({{bugzilla\|26}}) fix cache headers on anon talk page notification
	* ({{bugzilla\|874}}) added 'cgi' to {{wg\|FileBlacklist}}
	* ({{bugzilla\|862}}) localize date and time format for Finnish
	* ({{bugzilla\|548}}) Don't overwrite images until the user confirms it

	== MediaWiki 1.3.7, 2004-10-18 ==
	Changes from 1.3.6:
	* Fix protected-page related security issue.

	== MediaWiki 1.3.6, 2004-10-14 ==
	Changes from 1.3.5:
	* ({{bugzilla\|296}}) Variables in user interface messages are no longer
	substituted at install time, so changes to the site name etc should be easier
	to make
	* ({{bugzilla\|149}}) [[Special:RecentChanges]] "changes from" link preserves
	limit
	* ({{bugzilla\|433}}) tooltip for "Undelete" tab now labeled correctly
	* ({{bugzilla\|439}}) unclickable "Move" tab no longer displays on protected
	pages
	* ({{bugzilla\|484}}) graceful deletion of images where the actual file is
	missing
	* ({{bugzilla\|686}}) fixed [[plural]]s in Catalan localization
	* Fixed potential HTML/JavaScript injection attack in the
	[[Extension:UnicodeConverter\|UnicodeConverter]] extension. (This extension is
	not enabled by default.)
	* Fixed potential HTML/JavaScript injection attack via raw page views to a
	maliciously crafted wiki page.
	* ({{bugzilla\|187}}, {{bugzilla\|669}}) Fixed centered thumbnails, using
	{{code\|inline=y\|lang=html\|<div>}} instead of {{code\|inline=y\|lang=html\|<span>}}.
	* catch MySQL error 2000 during installation.
	* ({{bugzilla\|704}}) Removed misleading LocalSettings.sample
	* Fix cross site scripting bugs in [[Special:Ipblocklist]],
	[[Special:EmailUser]]
	* Fix SQL injection and cross site scripting bugs in Special:Maintenance
	* Fix cross site scripting bugs and possible filename validation vulnerability
	in ImagePage.
	* and more of that sort

	== MediaWiki 1.3.5, 2004-09-30 ==
	Changes from 1.3.4:
	* Clean up input validation in 'raw' page output mode which was a potential
	cross-site scripting opportunity.

	== MediaWiki 1.3.4, 2004-09-28 ==
	=== SECURITY NOTE ===
	As of 1.3.4, MediaWiki performs some screening of newly uploaded files for
	validity. (Some) corrupt image files, and HTML files mistakenly or maliciously
	masquerading as images, should now be rejected. These checks protect against
	Internet Explorer security holes relating to type autodetection which are a
	potential cross-site scripting attack vector, and also rejects at least one
	known version of the "JPEG virus" which might attack unpatched clients. If you
	already have invalid files uploaded this will not protect against them. If you
	have expanded the <code>filetype</code> whitelist or disabled the strict type
	checking, other dangerous file types may still get through. You should always
	be careful when allowing uploads!
	Changes from 1.3.3:
	* Fixed lots of template-related bugs, esp. for cases where template variables
	are used for links, images, etc.
	* Fixed transformation of page messages when viewing [[Special:Allmessages]]
	* Handle "ISBN ISBN 1234" correctly
	* Fixed warning on Category pages
	* Fixed some bad error messages on login page
	* Fixed history entry for initial main page on install
	* Removed problematic <code>{</code> and <code>}</code> from legal title
	characters
	* Strip leading blank from output in preformatted text.
	* Fixed problem when moving pages to titles with '#' in
	* Optional {{wg\|RawHtml}} for raw {{code\|inline=y\|lang=html\|<html>}} sections.
	Use only on limited- participation 'trusted' wikis, as it does not protect
	against cross-site scripting attacks. For security, this option can only be
	enabled if in {{wg\|WhitelistEdit}} mode.
	* Fixed problem where pages which were created as a redirect following a move
	never showed on [[Special:Randompage]].
	* Fixed line spacing on printed table of contents
	* Allow links to pages with names of the form [[RFC 1234]]
	* Fixed broken edit links being shown for sections from included templates
	* Verify that uploaded image files are of the claimed type.

	== MediaWiki 1.3.3, 2004-09-09 ==
	Changes from 1.3.2:
	* Fix for long numeric page titles
	* Fix Go search for "0", numeric almost-self-links
	* Avoid caching of pages with "You have new messages" headers
	* Fix for upgrades as non-root users from 1.2 command-line installs.
	* Fix for {{wg\|DebugDumpSql}} debug mode.
	* {{wg\|ExtraNamespaces}} setting for configuring additional namespaces (see
	note in {{manual\|DefaultSettings.php}})
	* 'recache' on query pages now disabled when miser mode is on; special case the
	global settings in your {{manual\|LocalSettings.php}} to do automatic updates.
	* Don't block UTF-8 titles containing byte 0xA0 (bug added in 1.3.2)
	* Watch/unwatch tabs now shown on edit pages in MonoBook.
	* Fix default skin in Irish localization (ga)
	* Add Traditional Chinese localization (zh-tw)
	* Changed default sortkey of subcategories. Don't include "Category:"-prefix
	any longer
	* More helpful info on spam catcher.
	* Allow larger offsets for queries such as [[Special:Listusers]]
	* Semicolon (;) added to French non-break space rules
	* Possible fix for some install errors with path names permission problems.
	* Removed [[Project:All system messages]], which has been superseded by the
	much faster [[Special:Allmessages]]. This speeds up installation considerably.

	== MediaWiki 1.3.2, 2004-08-30 ==
	Changes from 1.3.1:
	* Fix namespaced page creation links when no go match
	* When cookies are disabled, don't show login screen twice
	* Install should no longer die when PHP is pre-configured to compress output
	* Fixed bug that caused long Japanese pages to time out with Tidy active
	* When session.handler is set incorrectly, try automatic override to 'files'
	* Watch/Unwatch links back to the affected page instead of Main Page
	* Upload link no longer displayed on Monobook if uploading is disabled
	* Special:Allmessages faster, shows correct original text, works in safe mode

	== MediaWiki 1.3.1, 2004-08-14 ==
	Changes from 1.3.0:
	* Watchlist parameters now work with register_globals off
	* Fixed parsing of ''italics'' and '''bold''' mark-up (again)
	* Special:Allpages display is more sensible on smaller wikis
	* Fixed XHTML parsing error in classic skins
	* Moved pages update watchlist correctly
	* Fixed rebuildall.php on case-sensitive Unix filesystems
	* Disabled file cache compression by default due to incompatibility with output
	buffer compression (ob_gzhandler)
	* New magic word {{code\|inline=y\|PAGENAMEE}} (URL-escaped version of
	{{code\|inline=y\|PAGENAME}})
	* Installation avoids blank username; better message on missing XML module
	* {{wg\|WhitelistAccount}} no longer breaks all logins.

	== MediaWiki 1.3.0, 2004-08-11 ==
	Look & layout:
	* New default layout '[[Skin:MonoBook\|MonoBook]]' (available on PHP4 only
	currently)
	* Print stylesheet now built-in to every page
	* More or less correct XHTML 1.0 (served as text/html by default)
	Wiki features:
	* Image captions can now include links and other basic formatting
	* Image bounding box can be specified instead of width, e.g. as 100x100px,
	making the image not wider than 100px and not higher than 100px, keeping aspect
	ratio.
	* Templates have been expanded with parameters, and separated from the
	MediaWiki: localization scheme.
	* Categories more or less work
	* added a special page for listing users with sysop rights.
	Editing:
	* Automatic merging of edit conflicts that don't directly interfere
	* Edit summaries can now include basic formatting and links
	Metadata and output:
	* Linked Creative Commons copyright metadata (optional)
	* RSS 2.0 & Atom 0.3 feeds for Recent Changes, New Pages
	Optional modules:
	* WikiHiero hieroglyphic module can be added (separate download)
	* Timeline module can be added (separate download). Requires ploticus.
	* TeX now has an experimental MathML output mode (incomplete!)
	Installation and upgrading:
	* The old install.php and update.php have been removed. In-place installation
	introduced in 1.2 is now the standard installation and upgrade method, see
	INSTALL and UPGRADE for directions.
	Database:
	* The links table has been changed to use a cur_id for l_from. The link tables
	must be converted on upgrade, which may entail some downtime.
	Code and compatibility:
	* Should now run clean with error reporting set to E_ALL.
	* register_globals hack from 1.2 has been replaced with safer code
	* Bundled PHPTAL 0.7.0 from http://phptal.sourceforge.net/ (with some patches)
	* Most image-related code moved to Image.php
	* More fixes for PHP 4.1.2 (thanks to Asheesh Laroia)
	* URL encoding fix for anchors
	* All languages now available in UTF-8 mode
	* Various other fixes

	=== Caveats ===
	Some output, particularly involving user-supplied inline HTML, may not produce
	100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType
	= "application/xhtml+xml"; to test for remaining problem cases, but this is not
	recommended on live sites. (This must be set for MathML to display properly in
	Mozilla.) The new 'MonoBook' skin is not compatible with PHP 5 due to bugs in
	the underlying PHPTAL library. It will be automatically disabled when running
	on PHP5; the older look and feel will be used instead.
