Release notes

THIS IS NOT A RELEASE YET

MediaWiki 1.44 is a pre-release testing branch, and is not recommended for use in production.

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 1.44 upgrades are below:

• The default HTML markup used for headings has changed. Some skins may need updates. You can temporarily revert to the old markup by setting $wgParserEnableLegacyHeadingDOM to true (see below), but this option will be removed in the next release. See https://www.mediawiki.org/wiki/Heading_HTML_changes for more information.

For notes on 1.43.x and older releases, see HISTORY.

• (T382987) The default value of 'http.dnsbl.sorbs.net.' in $wgDnsBlacklistUrls has been removed. This is because sorbs.net have stopped providing their services. This means that if you have $wgEnableDnsBlacklist set to true, it will no longer provide any value unless you add other servers to $wgDnsBlacklistUrls.
• Google search removed (T384678): If site search is disabled with $wgDisableTextSearch but $wgSearchForwardUrl is not set to a URL to which to forward searches, then MediaWiki used to show a Google search form. This has been removed, and instead a notice is displayed. System administrators should set e.g. $wgSearchForwardUrl = 'https://duckduckgo.com?q=$1' to avoid this.
• The 'exception-json' log channel has been removed. It previously provided structured exception data in a custom machine-readable format. Since MediaWiki 1.26, structured exception data conforming to the PSR-3 logging standard is also available on the 'exception' log channel. (Log channels can be configured using $wgMWLoggerDefaultSpi.)
• $wgUsersNotifiedOnAllChanges now requires the listed users to have confirmed email addresses, just like other kinds of email notifications do. You can confirm the email address by logging in as the user and using "Confirm your email address" in user preferences, or by running a maintenance script: resetUserEmail.php --no-reset-password <username> <new-email>

• (T377829) $wgAutopromoteOnceRCExcludedGroups - Defaults to an empty list, can be used to define a denylist of user group names. One-shot autopromotions into these groups will never result in an RC entry, even if $wgAutopromoteOnceLogInRC is true, as long as they were the only new groups the user was autopromoted into.
• (T240542) $wgAutoblockExemptions - IP addresses and CIDR ranges listed here will not be affected by autoblocks, similar to MediaWiki:Block-autoblock-exemptionlist. Defaults to an empty list.

• (T13555) $wgParserEnableLegacyHeadingDOM now defaults to `false`. You can set it to `true` to temporarily restore the legacy HTML markup for wikitext headings in the output from the Parser, in case you find that your wiki's content or an extension is incompatible with the new markup. More information: https://www.mediawiki.org/wiki/Heading_HTML_changes This option will be removed in a future release.
• (T45646) $wgAllowRawHtmlCopyrightMessages now defaults to `false`, which means that the 'copyright-footer' and 'copyright-footer-history' wikitext messages will be used instead of 'copyright' and 'history_copyright' that supported raw HTML, and the 'SkinCopyrightFooter' hook will not be called. This helps protect your wiki against attacks by a rogue administrator account. You can set it to `true` to temporarily re-enable them until you can update your overrides. This option will be removed in a future release.
• (T386210) $wgAddGroups and $wgRemoveGroups now use the correct merge strategy of `array_merge_recursive`. This lets extensions add entries from the extension.json file, which would previously be silently ignored.
• (T382987) $wgDnsBlacklistUrls now defaults to an empty array. See the comment in the "Configuration changes for system administrators" section above.
• (T387856) $wgEnotifImpersonal and $wgEnotifMaxRecips are now deprecated.

• wgResourceLoaderUseObjectCacheForDeps, deprecated in 1.43, has been removed. It is now always enabled (T343492).
• wgBaseDirectory, unused, has been removed in favour of MW_INSTALL_PATH. If a variable value is needed, inject an optional parameter instead.

• (T363538, T204792) New parser functions {{#interlanguagelink:prefix|title}} and {{#interwikilink:prefix|title|caption}} to unambiguously create interlanguage and interwiki links, respectively, even when the "prefix" might conflict with a namespace on the local wiki.
• (T326057) Attempting to create a redirect to a nonexistent page will now result in a warning.
• (T33951) The Interwiki extension has been moved to MediaWiki core. It is now possible to view and edit the interwiki table without installing an extension. $wgInterwikiCentralDB and $wgInterwikiCentralInterlanguageDB have been removed, use $wgVirtualDomainsMapping['virtual-interwiki'] and $wgVirtualDomainsMapping['virtual-interwiki-interlanguage'] instead. $wgInterwikiViewOnly has been removed, (un)assign "interwiki" right instead.
• (T302140) Rollbacked edits are marked as manually patrolled instead of auto-patrolled since the rollback action was a manual patrol of the edit.
• (T56145) Introduces a new tag 'mw-recreated' to note edits which create pages that have been previously deleted by having an associated deletion log entry. This does not consider deletion log entries that were suppressed.
• (T326056) Attempting to create a redirect to another redirect will now result in a warning.
• (T322944) Developers using the Action API can now use the new crossorigin= parameter. If used with a supported session provider, such as OAuth, this permits authenticated cross-origin requests against the Action API, similar to how origin=* allows unauthenticated cross-origin requests.
• (T24521, T62109) Embedding a file (e.g., [[File:MediaWiki.png]]) on a page protected with cascading protection will no longer restrict edits to the file description page, only file uploads. Transcluding a file description page (e.g., {{:File:MediaWiki.png}}) will now restrict edits to the page.

• (T267477) Users with rename userright can now rename themselves through [[Special:RenameUser]].
• (T104830) [[Special:RenameUser]] can now be used in wiki families using shared tables. A renameuser-global right is added and required when renaming global users. No groups have this right by default.
• (T310051) uppercase-ckb collation added. uca-xx-ckb collation deprecated

• The AuthenticationAttemptThrottled hook was added.
• The CodexTablePager class was added.
• UserFactory now has newFromNameOrIp() method to quickly create a User object for either an IP or a named user.
• The ApiQueryCheckCanExecute hook was added.
• The ChangesListInsertLogEntry hook was added.
• The TempUserDetailsLookup service was added.
• The UserLinkRenderer service was added.
• The AuthPreserveQueryParams hook has a new option, $options['request'], to avoid having to rely on the global context.
• You can use LoggerFactory::getContext() to add extra context to all PSR-3 log events.
• New helper methods Html::addClass() and Html::expandClassList().

• (T377856) Updated the autonym for Shan (shn)
• (T379137) Added language support for Hunde (hke).
• (T381463) Added language support for Coptic (cop).

• In StatusValue::replaceMessage(), ::hasMessage() and ::hasMessagesExcept() passing MessageSpecifier or MessageValue as $source, deprecated in 1.43, is no longer allowed.
• StatusValue will no longer accept errors given as a MessageSpecifier combined with a parameters array. This was deprecated in 1.43.
• The methods MessageValue::objectParams(), Message::objectParams() and Message::objectParam(), deprecated in 1.43, have been removed.

• Public access to OutputPage::mModules and OutputPage::mModuleStyles, deprecated in 1.38, has been removed.
• Return type declarations were added to methods in `includes/libs/Message`, specifically in the `MessageSpecifier`, `ITextFormatter`, and `IMessageFormatterFactory` interfaces. This update enhances type safety but may require updates in any classes implementing these interfaces, including external extensions. Extensions such as Translate, Flow, and ReadingLists require compatibility patches to support these changes.
• EditPage::internalAttemptSave(), deprecated since 1.43, was removed.
• IDatabase::LB_TRX_ROUND_ID was removed and IDatabase::LB_READ_ONLY_REASON was marked as an internal constant.

• The ParsoidOutputAccess class marked @unstable from creation and deprecated with all of its methods in 1.43, has been removed.
• (T382030) MediaWiki core database schema and schema changes have been moved to a new top-level sql/ directory. This should only affect code directly referencing the old paths.
• The HtmlToContentTransform::setMetrics() and HtmlInputTransformHelper::setMetrics() methods now require a StatsFactory argument. Passing a StatsdDataFactoryInterface was deprecated in 1.43.
• The method ParserOptions::setupFakeRevision has been marked internal. It will remain backwards compatible in 1.44 but may change without notice in 1.45 or later.
• The Less mixin .column-break-after-avoid(), deprecated in 1.43, has been removed. Use just the CSS rule `break-after: avoid-column;` instead now.
• ApiBase::errorArrayToStatus(), deprecated in 1.43, has been removed.
• ZipDirectoryReader has been moved to the Wikimedia\Mime library. No callers outside that library are known.

• The IDatabase transaction lifecycle callbacks onTransactionResolution(), onTransactionPreCommitOrIdle() and onTransactionCommitOrIdle() no longer receive a DB connection handle as an argument. (T386190)
• The $schema parameters to DatabaseBlockStore::getQueryInfo() and  ::getRangeCond() have been removed. They were documented as temporary migration support parameters. Support for ipb_* field aliases in DatabaseBlockStore::newFromRow(), which was meant to support the use of $schema, has been removed.
• The following old class aliases, deprecated in MediaWiki 1.40, have now been dropped: - \ActorMigration — use \MediaWiki\User\ActorMigration - \ActorMigrationBase — use \MediaWiki\User\ActorMigrationBase - \AtomFeed — use \MediaWiki\Feed\AtomFeed - \CategoriesRdf — use \MediaWiki\Category\CategoriesRdf - \Category — use \MediaWiki\Category\Category - \CategoryViewer — use \MediaWiki\Category\CategoryViewer - \ChannelFeed — use \MediaWiki\Feed\ChannelFeed - \CommentStore — use \MediaWiki\CommentStoreCommentStore - \ContentSecurityPolicy — use \MediaWiki\Request\ContentSecurityPolicy - \DeprecatedGlobal — use \MediaWiki\StubObject\DeprecatedGlobal - \DerivativeRequest — use \MediaWiki\Request\DerivativeRequest - \EditPage — use \MediaWiki\EditPage\EditPage - \FauxRequest — use \MediaWiki\Request\FauxRequest - \FauxRequestUpload — use \MediaWiki\Request\FauxRequestUpload - \FauxResponse — use \MediaWiki\Request\FauxResponse - \FeedItem — use \MediaWiki\Feed\FeedItem - \FeedUtils — use \MediaWiki\Feed\FeedUtils - \FileDeleteForm — use \MediaWiki\Page\File\FileDeleteForm - \ForeignResourceManager — use \MediaWiki\ResourceLoader\ForeignResourceManager - \FormOptions — use \MediaWiki\Html\FormOptions - \Html — use \MediaWiki\Html\Html - \LinkFilter — use \MediaWiki\ExternalLinks\LinkFilter - \Linker — use \MediaWiki\Linker\Linker - \ListToggle — use \MediaWiki\Html\ListToggle - \MagicWord — use \MediaWiki\Parser\MagicWord - \MagicWordArray — use \MediaWiki\Parser\MagicWordArray - \MagicWordFactory — use \MediaWiki\Parser\MagicWordFactory - \MergeHistory — use \MediaWiki\Page\MergeHistory - \MovePage — use \MediaWiki\Page\MovePage - \PageProps — use \MediaWiki\Page\PageProps - \PathRouter — use \MediaWiki\Request\PathRouter - \ProtectionForm — use \MediaWiki\Page\ProtectionForm - \RSSFeed — use \MediaWiki\Feed\RSSFeed - \StubGlobalUser — use \MediaWiki\StubObject\StubGlobalUser - \StubObject — use \MediaWiki\StubObject\StubObject - \StubUserLang — use \MediaWiki\StubObject\StubUserLang - \TemplateParser — use \MediaWiki\Html\TemplateParser - \TemplatesOnThisPageFormatter — use \MediaWiki\EditPage\TemplatesOnThisPageFormatter - \Title — use \MediaWiki\Title\Title - \TrackingCategories — use \MediaWiki\Category\TrackingCategories - \WebRequestUpload — use \MediaWiki\Request\WebRequestUpload - \WebResponse — use \MediaWiki\Request\WebResponse - \WikiMap — use \MediaWiki\WikiMap\WikiMap - \WikiReference — use \MediaWiki\WikiMap\WikiReference - \MediaWiki\BadFileLookup - use \MediaWiki\Page\File\BadFileLookup - \MediaWiki\HeaderCallback - use \MediaWiki\Request\HeaderCallback - \MediaWiki\HtmlHelper - use \MediaWiki\Html\HtmlHelper
• Block::TYPE_ID has been removed. Use DatabaseBlockStore::newFromID().
• UserOptionsManager methods resetOptions, listOptionKinds and getOptionKinds, deprecated since 1.43, have been removed.
• WANObjectCache::clearLastError(), deprecated in 1.38 & emitting notices since 1.43, has been removed.
• The WANObjectCache 'stats' option for StatsdDataFactory, deprecated in 1.43, is no longer supported. Use StatsFactory instead.
• When fetching a message containing {{PAGENAME}} or similar with wfMessage(...)->text(), the title used will be Special:Badtitle unless a context title was set with e.g. Message::setContext(). In the past, the title used in a previous call was sometimes used.
• MediaWikiTitleCodec has been split. TitleParser and TitleFormatter are now classes rather than interfaces. Remove all references to MediaWikiTitleCodec.
• A new abstract method, CentralIdLookup::lookupUserNamesWithFilter(), was added. This is a breaking change for extensions that extend this class.
• UserOptionsStore::fetchBatchForUserNames() was added. This is a breaking change for extensions that implement the interface.
• Callbacks registered by MessageCacheFetchOverrides handlers will now be called with only two parameters. The $language and $useDB parameter will not be passed.
• The following formerly-public properties of OutputPage, deprecated with warnings in 1.38, have been removed: - OutputPage::$mNoGallery - OutputPage::$mRevisionTimestamp
• OutputPage::formatPermissionsErrorMessage(), deprecated since 1.36, has been removed. Use formatPermissionStatus() instead.
• BaseTemplate::getFooterIcons(), deprecated since 1.35, has been removed.
• The method signatures of EmailNotification::notifyOnPageChange() and actuallyNotifyOnPageChange() have changed. These method are now marked as @internal and must not be used by extensions.
• The modules codex-search-styles and @wikimedia/codex-search have been removed. Please use MediaWiki\\ResourceLoader\\CodexModule instead.
• SpecialBlock::processForm(), SpecialBlock::parseExpiryInput() and SpecialBlock::canBlockEmail(), deprecated in 1.36, and SpecialBlock::getSuggestedDurations(), deprecated in 1.42, has been removed.

• Various static methods on ChangeTags, deprecated since 1.41, each now emit deprecation warnings. Use service access to the ChangeTagsStore instead: addTags(), defineTag(), deleteTagEverywhere(), getDisplayTableName(), getSoftwareTags(), getTags(), getTagsWithData(), listDefinedTags(), listExplicitlyDefinedTags(), listSoftwareActivatedTags(), listSoftwareDefinedTags(), makeTagSummarySubquery(), modifyDisplayQuery(), purgeTagCacheAll(), tagUsageStatistics(), and updateTags().
• EditPage::$textbox2 has been deprecated (once again).
• EditPage::$action, deprecated since 1.38, now emits deprecation warnings.
• (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.

• (T353570) The trait Wikimedia\Reflection\GhostFieldAccessTrait is deprecated. It is planned to be removed in 1.45. No replacement is provided.
• WikiPage::doEditUpdates(), deprecated since 1.32, is now emitting warnings. Use DerivedPageDataUpdater::doUpdates() instead.
• Title::deleteTitleProtection(), deprecated in 1.37, now emits warnings. Use RestrictionStore::deleteCreateProtection() instead.
• IDatabase::setTransactionListener() is now deprecated without replacement.
• ILoadBalancer::setTransactionListener() is now deprecated without replacement.
• ILBFactory::setWaitForReplicationListener() is now deprecated without replacement.
• Maintenance::beginTransaction(), Maintenance::commitTransaction(), Maintenance::rollbackTransaction(), and Maintenance::waitForReplication() are now deprecated. Use Maintenance::*TransactionRound() instead.
• Sanitizer::mergeAttributes() has been deprecated.
• TextboxBuilder::mergeClassesIntoAttributes() has been deprecated.
• The ReverseArrayIterator class, unused since 1.32, has been deprecated.
• OutputPage::parserOptions() has been deprecated; use ParserOptions::newFromContext( $outputPage->getContext() ) instead.

More information is available at T333211. To avoid future breakage, see the guidance in T385346.

• The ArticleProtect and ArticleProtectComplete hooks are now called when WikiPage::doUpdateRestrictions is called to protect a non-existing title.
• Introduce ISearchResultSet::isApproximateTotalHits() (defaults to false in BaseSearchResultSet) to let SearchEngine implementations run optimizations that might lead to innacurate computation of the exact number of pages matching the search query.
• (T367441) ResourceLoader Debug mode now defaults to debug mode v2. This means ?debug=true now maps to debug=2. Unlike debug mode v1, this doesn't load each file from disk, and your code looks the same as it is in production with closures that prevent global variable leakage.
