+Change notes from older releases. For current info see RELEASE-NOTES-1.27.
+
+== MediaWiki 1.25 ==
+
+=== 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.
+
+
+== Compatibility ==
+
+MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
+HHVM 3.3.0.
+
+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 ==
+
+1.25 has several database changes since 1.24, 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 1.24.x and older releases, see HISTORY.
+
+== MediaWiki 1.24 ==
+
+=== 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 getLang() from IContextSource and subclasses. (deprecated since 1.19)
+* 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 DatabaseMysqlBase::getLagFromProcesslist(). (deprecated since 1.19)
+* Removed LoadBalancer::closeConnecton(). (deprecated since 1.18)
+* Removed ApiBase::createContext(). (deprecated since 1.19)
+* BREAKING CHANGE: The undocumented Special{$this->getName()}BeforeFormDisplay
+ set of hooks has been removed and replaced by a single new hook
+ SpecialPageBeforeFormDisplay.
+* (bug 65781) Removed block warning on included {{Special:Contributions}}
+* Removed Skin::makeGlobalVariablesScript(). (deprecated since 1.19)
+* Removed MWNamespace::isMain(). (deprecated since 1.19)
+* Removed Preferences::loadOldSearchNs(). (deprecated since 1.19)
+* Removed OutputPage::getStatusMessage(). (deprecated since 1.18)
+* Removed OutputPage::isUserJsAllowed(). (deprecated since 1.18)
+* Removed Title::updateTitleProtection(). (deprecated since 1.19)
+* Removed ParserOptions::setSkin(). (deprecated since 1.19)

+* Removed User::isValidEmailAddr(). (deprecated since 1.18)
+* Removed Title::getEscapedText(). (deprecated since 1.19)
+* Removed Language::getFallbackLanguageCode(). (deprecated since 1.19)

+ 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.
