  • (task T210998) Properly set $wgLanguageCode in the generated LocalSettings.php if --lang is used with the command-line installer (install.php).

Configuration changes in 1.32[edit]

New configuration[edit]

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

Changed configuration[edit]

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

Removed configuration[edit]

New features in 1.32[edit]

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

External library changes in 1.32[edit]

New external libraries[edit]

Changed external libraries[edit]

Removed external libraries[edit]

  • pear/mail_mime-decode was removed.

Bug fixes in 1.32[edit]

  • SpecialPage::execute() will now only call checkLoginSecurityLevel() if getLoginSecurityLevel() returns non-false.
  • (T43720, T46197) Improved page display title handling for category pages.
  • (task T65080) Fixed resetting options of some types via API action=options.
  • (task T198054) Fixed login crash caused by invalid/unknown language code for the 'uselang' parameter.

Action API changes in 1.32[edit]

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

Action API internal changes in 1.32[edit]

  • Added 'ApiParseMakeOutputPage' hook.
  • Parameter names may no longer contain '{' or '}', as these are now used for templated parameters.
  • (task T194950) Added 'ApiMaxLagInfo' hook.
  • The following methods now take a RevisionRecord rather than a Revision. No external callers are known.
    • ApiFeedContributions::feedItemAuthor()
    • ApiFeedContributions::feedItemDesc()
    • ApiQueryRevisionsBase::extractRevisionInfo()
  • The following deprecated methods have been removed:
    • ApiBase::profileIn() (deprecated in 1.25)
    • ApiBase::profileOut() (deprecated in 1.25)
    • ApiBase::safeProfileOut() (deprecated in 1.25)

    • ApiUsageException::getMessageArray() (deprecated in 1.29)
  • Class UsageException, deprecated in 1.29, has been removed.
  • ApiErrorFormatter: Added getFormat() and newWithFormat(). In particular, you can now easily test $formatter->getFormat() === 'bc', and then call $formatter->newWithFormat( 'plaintext' ) to get a non-BC formatter.

Languages updated in 1.32[edit]

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

  • The deprecated UTF8_ and UNICODE_ constants were removed. The class constants from the UtfNormal\Constants class from the utfnormal library should be used
  • The protected methods PHPSessionHandler::returnSuccess() and returnFailure(), only needed for PHP5 compatibility, have been removed. It now uses the boolean values `true` and `false` respectively.

  • Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were removed. Use addLink() instead.
  • Another two OutputPage methods, setPageTitleActionText() and getPageTitleActionText(), were removed. They did nothing since 1.15 (almost ten years). Use setHTMLTitle() directly.
  • The return value of OutputPage::adaptCdnTTL() has been removed. The value returned was misleading and probably not what any caller would have wanted.
  • All MagicWord static member variables have been removed. Use appropriate hooks or MagicWordFactory methods instead.
  • MagicWord::clearCache() has been removed. Instead, create a new MagicWordFactory, such as by calling resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
  • mw.util.init() has been removed. This function is not needed anymore and was a no-op function since 1.30.
  • SpecialPageFactory::resetList() is a no-op. Call overrideMwServices() instead.
  • MediaWiki no longer supports a StartProfiler.php file. Instead, you can set $wgProfiler and $wgEnableProfileInfo .
  • The mw.loader.addSource() is now considered a private method, and no longer supports the `id, url` signature. Use the `Object` parameter instead.
  • The backwards-compatibility code in HTMLForm to add a drop-down control to an option that is not set to be a drop-down if the "mw-chosen" class is present, is now removed.
  • Several collations were removed. They were workarounds for bugs in the ICU library and they are no longer needed (as of ICU 57.1):
    • 'uppercase-se' (NorthernSamiUppercaseCollation) - use 'uca-se' instead
    • 'xx-uca-et' (CollationEt) - use 'uca-et' instead
    • 'xx-uca-fa' (CollationFa) - use 'uca-fa' instead
  • LanguageCode::bcp47() now always returns a valid BCP 47 code. This means that some MediaWiki-specific language codes, such as `simple`, are mapped into valid BCP 47 codes (eg `en-simple`).
  • The hooks 'SpecialRecentChangesFilters' & 'SpecialWatchlistFilters' deprecated in 1.23 were removed. Instead, use 'ChangesListSpecialPageStructuredFilters'. The ChangesListSpecialPage code for these legacy hooks, and their use in SpecialRecentchanges.php and SpecialWatchlist, was also removed:
    • ChangesListSpecialPage->getCustomFilters()
    • ChangesListSpecialPage->getFilterGroupDefinitionFromLegacyCustomFilters()
    • ChangesListSpecialPage::customFilters
  • The global function wfUseMW, deprecated since 1.26, has now been removed. Use the "requires" property of static extension registration instead.
  • $wgSpecialPages no longer accepts array syntax, deprecated since 1.18.
  • The MailAddress constructor can no longer be called with a User object, behaviour which has been deprecated since 1.24.
  • LBFactory, deprecated since 1.28, has been removed. Instead, use Wikimedia\Rdbms\LBFactory.
  • The MimeMagic class, deprecated since 1.28 has been removed. Get a MimeAnalyzer instance from MediaWikiServices instead.
  • The '--tidy' option to maintenance/parse.php has been removed. Tidying the output is now the default. Use '--no-tidy' to bypass the tidy phase.
  • The global function wfErrorLog, deprecated since 1.25, has now been removed. Use MWLoggerLegacyLogger::emit or UDPTransport.
  • The hooks 'SpecialRecentChangesQuery' & 'SpecialWatchlistQuery', deprecated in 1.23, were removed. Instead, use ChangesListSpecialPageStructuredFilters or ChangesListSpecialPageQuery.
  • The global function wfUsePHP, deprecated since 1.30, has now been removed. To assert a newer version of PHP than MediaWiki does, use extension registration.
  • The hook 'ChangesListSpecialPageFilters', deprecated in 1.29, has now been removed. Use the 'ChangesListSpecialPageStructuredFilters' hook instead.
  • DeferredUpdates::setImmediateMode(), deprecated since 1.29, has been removed.
  • File / MediaHandler::getStreamHeaders(), deprecated since 1.30, was removed.
  • The hook 'DoEditSectionLink', deprecated since 1.25, has been removed. Use the hook 'SkinEditSectionLinks' instead.
  • The hook 'UserGetImplicitGroups', deprecated since 1.25, has been removed.

    • ApiBase::profileOut() (deprecated in 1.25)
    • ApiBase::safeProfileOut() (deprecated in 1.25)

  • MediaWiki no longer has a 'JavaScript-powered' wikitext toolbar built in. The old "bulletin board style toolbar", known as "the 2006 wikitext editor", has been removed, and instead sysadmins will be required to choose one (or more) of the several extensions available for this purpose if they need the functionality. The MediaWiki "tarball" releases have included the replacement extension for this, the WikiEditor extension aka "the 2010 wikitext editor", for many years now. As part of this, several parts of MediaWiki have been removed or simplified:
    • The user option 'showtoolbar' (shown as "Show edit toolbar") is no longer available; if an extension adds a toolbar via the EditPageBeforeEditToolbar hook, it will be shown; extensions should provide a specific user preference to disable themselves as needed.
    • The public methods Language::getImageFile() and ::getImageFiles(), and the related specification of $imageFiles within individual languages' code file, as well as the referenced static media assets, all of which were only used inside MediaWiki itself for providing the icons for the old toolbar, have been removed without explicit deprecation.
    • The internal ResourceLoader module "mediawiki.toolbar", which is unused except by MediaWiki itself and back-compatibility code, has been removed.
    • The internal ResourceLoaderEditToolbarModule class has been removed.

Deprecations in 1.32[edit]

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

Other changes in 1.32[edit]


MediaWiki 1.32 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 7.0.13 or later for long term support. MediaWiki requires that the mbstring, xml, ctype, json, iconv and fileinfo PHP extensions are loaded to work.

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

The supported versions are:

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


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

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

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

For notes on 1.31.x and older releases, see HISTORY.

Online documentation[edit]

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

Mailing list[edit]

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

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

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