			== 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.

			* (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::set_target() & ::get_targets(), and OutputPage::set_target(),
			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
			- PostgresInstaller
			- PostgresUpdater
			- SqliteInstaller

			* The file mediawiki.ui/utilities.less, with its three layout CSS classes, has
			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.

			=== 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.

			bootstrap.integration.php and suite.xml. Run tests with `composer phpunit`
			instead, or simply `vendor/bin/phpunit`, which use bootstrap.php and

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

			no longer do anything and have been deprecated.
			* DatabaseBlock::doAutoblock and ::updateTimestamp are now deprecated, use
			DatabaseBlockStore::doAutoblock and ::updateTimestamp instead.

			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.

			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::getTimestamp() and ::setTimestamp() have been deprecated; use
			::getRevisionTimestamp() and ::setRevisionTimestamp() instead.
			* ParserOutput::setText() has been deprecated; use ::setRawText() instead which
			matches the name of the corresponding getter, ParserOutput::getRawText().
			* ParserOutput::addTemplate() will emit a deprecation warning if it is called
