For current info see RELEASE-NOTES-1.26. + +== 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.
