MediaWiki 1.35.1[edit]

This is a security and maintenance release of the MediaWiki 1.35 branch.

While normally running update.php isn't required for point releases, it is recommended to run it for 1.35.1 so that sites.site_language is updated to take 35 characters.

Watchlist Expiry is no longer considered experimental, but is off by default. To enable it, set $wgWatchlistExpiry = true; in your LocalSettings.php.

MediaWiki 1.35.0-rc.0[edit]

Upgrading notes for 1.35[edit]

1.35 requires PHP 7.3.19 or above (up from 7.2.9). (task T257879)

1.35 has several database changes since 1.34, 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!

MediaWiki 1.35 is the next LTS after 1.31, and will be supported for around 3 years.

MediaWiki has a lot of both soft and hard deprecations, and code removed. As always, make sure your versions of extensions match the MediaWiki version, and updates may be required to any custom extensions.

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

Some specific notes for MediaWiki 1.35 upgrades are below:

  • (task T259685) Zeroconf (zero-configuration) VisualEditor/Parsoid doesn't work using SQLite as the database backend for MediaWiki. This is due to the lack of write concurrency in SQLite. If you wish to use this feature, it is recommended to use MySQL/MariaDB rather than SQLite.

For notes on 1.34.x and older releases, see HISTORY.

Configuration changes for system administrators in 1.35[edit]

New configuration[edit]

  • $wgDiffEngine — This can be used to specify the difference engine to use, rather than MediaWiki choosing the first of $wgExternalDiffEngine , wikidiff2, or php that is usable.
  • $wgSearchMatchRedirectPreference — This configuration setting controls whether users can set a new preference, search-match-redirect, which decides if search should redirect them to exact matches is available. By default, this is set to false, which maintains the previous behaviour without preference bloat. Change your site's default by setting $wgDefaultUserOptions ['search-match-redirect'].
  • $wgPoolCounterConf ['SpecialContributions'] — Per-user concurrency in the use of SpecialContributions can now be limited by setting this appropriately.
  • $wgPasswordPolicy — PasswordCannotBeSubstringInUsername is a new password policy check. Similar to the existing PasswordCannotMatchUsername check, this check ensures that a user's (case-insensitive) password cannot be a part of their username. e.g. password = MyPass, username = ThisUsersPasswordIsMyPass.
  • $wgLogos — This new configuration setting combines the now-deprecated $wgLogo and $wgLogoHD settings into a single, associative array. It provides support for a new key, 'wordmark', for setting a horizontal wordmark to show next to the graphical logo. To do this, set 'wordmark' to an array with 'src' set to the path of the wordmark image, and 'width' and 'height' for its dimensions in pixels. $wgLogos inherits the existing support provided by its predecessor settings: '1x' mapping to the path of the logo as a 135x135px raster image (equivalent to $wgLogo ), and '1.5x', '2x', and 'svg' operating as before for $wgLogoHD . If $wgLogos is unset, $wgLogo and $wgLogoHD values are read for temporary backwards compatibility. (task T232140)
  • $wgWatchlistExpiry — (EXPERIMENTAL) This enables the new watchlist expiry feature. The database table (watchlist_expiry) for this is created regardless of this setting, but all other aspects of the expiry feature are controlled by it. Enabling in production is discouraged for the time being. A future MediaWiki 1.35 release will advertise this feature once it is stable.
  • $wgWatchlistPurgeRate — This sets the chance of expired watchlist items being purged on each page edit. Only has effect if $wgWatchlistExpiry is true.
  • $wgWatchlistExpiryMaxDuration — This is the maximum definite relative duration for watchlist expiries. Only has effect if $wgWatchlistExpiry is true.
  • $wgImgAuthPath – This can be used to override the path prefix used when handling img_auth.php requests. (task T235357)
  • $wgAllowedCorsHeaders — This is a list of headers which can be used in a cross-site API request.
  • $wgHTTPMaxTimeout and $wgHTTPMaxConnectTimeout — These allow site administrators to limit the timeouts used by the HTTP client libraries. This only affects callers using HttpRequestFactory and the deprecated wrappers in the Http class.
  • $wgCdnMaxageStale — This controls the Cache-Control s-maxage header for page views when PoolCounter lock contention indicates that a stale cache entry should be sent.
  • $wgForceHTTPS — This makes the HTTP to HTTPS redirect be unconditional and suppresses various hacks needed to support mixed HTTP/HTTPS wikis. We recommend this be set to true on pure HTTPS wikis.
  • $wgCookieSameSite — This setting allows login cookies to be sent with SameSite=None. This is required for cross-site CentralAuth auto-login after Chrome 84.
  • $wgUseSameSiteLegacyCookies — This adds a compatibility hack to SameSite=None cookies for browsers which implemented an incompatible draft version of the specification.

Changed configuration[edit]

  • $wgResourceLoaderMaxage (task T235314) — This configuration array controls the max-age for HTTP caching through the Cache-Control header. It has uses the "versioned" key for urls that do have a version parameter, and the "unversioned" key for urls without a version parameter. The sub keys for "client" and "server" are no longer supported in MediaWiki 1.35.
  • $wgEnableOpenSearchSuggest — This boolean variable is deprecated and no longer used. The OpenSearch API is now always enabled.
  • $wgAuthManagerConfig and $wgAuthManagerAutoConfig — These can now use the 'services' option in provider specifications.
  • $wgVirtualRestConfig ['modules']['parsoid'] —
    • The defaults have been updated. If you were relying on the default values, you may need to update your configuration.
    • The 'URL' parameter, previously allowed for backwards-compatibility, has been deprecated. Use 'url' instead.
  • $wgXmlDumpSchemaVersion — Default is now set to XML_DUMP_SCHEMA_VERSION_11, so dumps use the new dump format per default. Consumers of XML dumps should not be affected if they ignore any unknown tags they encounter. Also, the format is effectively unchanged for revisions that only contain the main slot. The --schema-version option can be used with the dumpBackup.php script to set the dump format. (task T238921)
  • $wgParserConf — This configuration is now deprecated. It has been effectively constant since 2008, and is ignored by core code. Configure the ParserFactory service in order to customize the Parser used.
  • $wgAutoloadAttemptLowercase — This has been deprecated, and the default value changed to false.
  • $wgAllowImageMoving — This configuration setting is now deprecated. Instead, use $wgGroupPermissions ; e.g., to revoke sysops' ability to move images use $wgGroupPermissions ['sysop']['movefile'] = false.
  • $wgAllowImageTag — This configuration is now deprecated; future parsers will not support direct use of the HTML ‎<img> tag in wikitext.
  • $wgUseTwoButtonsSearchForm — This has been deprecated. If you maintain a skin that relies on this and wishes to let system administrators change it, you should convert it to a config variable specific to your skin. If you're using it to configure your wiki, you should check individual skins to see whether they have local skin config for the feature and use that.
  • $wgPasswordPolicy — The deprecated policy 'PasswordCannotBePopular' has been removed. Use PasswordNotInCommonList instead which covers many more passwords.
  • Backwards compatibility for using an associative array (e.g. [ '127.0.0.1' => 'bad-ip' ]) for $wgProxyList has been removed. This was deprecated since 1.30. Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
  • $wgShellRestrictionMethod — This now defaults to 'autodetect', which will enable sandboxing for shell commands using firejail, if it's installed. To disable restrictions, set it to false.
  • $wgLegacyJavaScriptGlobals – This deprecated setting now default to false, instead of true, ahead of its planned removal.

Removed configuration[edit]

New user-facing features in 1.35[edit]

  • (task T204618) Whitelisted the aria-hidden HTML attribute for all elements in wikitext.
  • (task T13456) Special:EditPage, Special:PageHistory, Special:PageInfo, and Special:Purge have been created as shortcuts for each action. Special:EditPage/Foo redirects to title=foo&action=edit, with PageHistory, PageInfo, and Purge corresponding to action= history, info, and purge respectively. When linked to, its subpage is used as the target. Otherwise, it displays a basic interface to allow the end user to specify the target manually.
  • (task T139221) The generated table of contents is now a navigation landmark role for assistive technologies.
  • (task T245931) interwiki map API doesn't report foreign language if $wgInterwikiMagic =false
  • The form at ?action=watch has a new dropdown list to support expiry dates for watchlist items (if $wgWatchlistExpiry is true).

New developer features in 1.35[edit]

  • A Docker based local development develpoment environment configuration is included (task T238224) and DEVELOPERS.md has been added with usage documentation and links to further help.
  • If CSP is enabled, extensions can now add additional sources using the ContentSecurityPolicy::addDefaultSource, ::addStyleSrc and ::addScriptSrc methods (e.g. $context->getOutput()->getCSP()->addDefaultSrc( 'example.com' ))
  • Extensions can now specify classes and namespaces to be autoloaded by the test autoloader, by setting the "TestAutoloadNamespaces" and "TestAutoloadClasses" properties in extension.json. (task T196090)
  • (task T250977) extension.json now allows "SearchMappings" which maps the canonical name of the search engine (used in wgSearchType and wgSearchTypeAlternatives) to a specification using the ObjectFactory specification. This allows extensions to register Search Engines using namespaced classes.
  • Added getters for OutputPage's robot, index and follow policies; getRobotPolicy() returns the entire policy as a string in the form <index policy>,<follow policy> while getIndexPolicy() and getFollowPolicy() return their respective policies as a string.
  • The ResourceLoaderSiteModulePages and ResourceLoaderSiteStylesModulePages hooks were added to allow changing which wiki pages these modules contain.
  • The SkinFactory now allows skins to be specified as an ObjectFactory spec, allowing the construction of skins with services injected.
  • ContentHandlerFactory for most ContentHandler static methods. It has been added to the constructors for many classes to improve SOLID / GRASP.
  • FileDeleteForm's constructor now accepts a user as the second parameter. Support for not passing a user has also been hard-deprecated and will be removed in 1.36.
  • The ParserPreSaveTransformComplete hook was added.
  • The ParserBeforePreprocess hook was added.
  • The ResourceLoaderSkinModule class now has a "legacy" feature that loads the stylesheets previously part of the "mediawiki.legacy.shared" and "mediawiki.legacy.commonPrint" module. Those modules are now deprecated and no longer loaded by skins. For skins needing to retain these styles, you will need to load these styles via a module using the ResourceLoaderSkinModule class. See Vector and Monobook for examples.
  • ParserOutput now has methods addExtraCSPStyleSrc, addExtraCSPDefaultSrc, addExtraCSPScriptSrc for parser tags/functions to be able to add sources to the Content Security Policy.
  • The HtmlCacheUpdater service was added to unify the logic of purging CDN cache and HTML file cache to simplify callers and make them more consistent.
  • The MultiHttpClient code will fallover to non-curl if curl_multi* is blocked.
  • Preferences which use HTMLTitlesMultiselectField can make use of MultiTitleFilter class for saving title text to/from article IDs in user preferences.
  • OutputPage::addHtmlClasses() was added to allow injecting CSS classes on to the ‎<html> element on page load.
  • The SkinAddFooterLinks hook is added to allow extensions to add items to skin footers. Previously this had to be done via SkinTemplateOutputPageBeforeExec . Doing so using that hook is now hard deprecated.
  • A new BlockPermissionChecker service was introduced for checking block-related permissions.
  • The support of 'database' type of extensions has been added to allow 3d party databases like Percona be used as storage. See task T226857, task T253248.
  • Three new return parameters have been added to the EditPageGetCheckboxesDefinition hook. Handlers of this hook are no longer restricted to defining checkboxes. See the documentation of EditPage::getCheckboxesDefinition() for more details.
  • New flag File::RENDER_TMP was added in order to allow File::generateAndSaveThumb and File::trasform to render a thumbnail without saving it to the storage.

  • The jquery.getAttrs module was removed.

Action API changes in 1.35[edit]

  • The 'suggest' parameter of action=opensearch has been deprecated. The API behaves the same with and without this parameter. It was previously used by $wgEnableOpenSearchSuggest to partially disable the API if set to false. Specifically, it would deny internal frontend requests carrying this parameter, whilst accepting other requests.
  • Integer-type parameters are now validated for syntax rather than being interpreted in surprising ways. For example, the following will now return a badinteger error:
    • "1.9" (formerly interpreted as "1")
    • " 1" (formerly interpreted as "1")
    • "1e1" (formerly interpreted as "1" or "10", depending on the PHP version)
    • "1foobar" (formerly interpreted as "1")
    • "foobar" (formerly intepreted as "0") parameters. Ranges should be assumed to be enforced.
  • Many user-type parameters now accept a user ID, formatted like "#12345".
  • The 'assert' parameter used by all API modules now supports the value 'anon'. When specified, the API will return the 'assertanonfailed' error if the user is logged in.
  • action=edit now supports the 'baserevid' parameter for edit conflict detection, as an alternative to 'basetimestamp'. Note that self-conflicts will continue to be ignored if 'basetimestamp' is set, but not if only 'baserevid' is set.
  • A new module was added to change the content model of existing pages. Use action=changecontentmodel. Unlike Special:ChangeContentModel, the api module does not work for pages that do not already exist.
  • If $wgWatchlistExpiry is true, the following API changes are made:
    • action=watch accepts a new 'expiry' parameter analagous to the expiry accepted by action=userrights, action=block, etc., except it must be no greater than $wgWatchlistExpiryMaxDuration , or an infinity value.
    • action=query&list=watchlistraw returns pages' watchlist expiry dates.
  • (task T249526) action=login will now return Failed rather than NeedToken on session loss.

Action API internal changes in 1.35[edit]

  • The Action API now uses the Wikimedia\ParamValidator library for parameter validation, which brings some new features and changes. For the most part existing module code should work as it did before, but see subsequent notes for changes.
    • The values for all ApiBase PARAM_* constants have changed. Code should have been using the constants rather than hard-coding the values.
    • Several ApiBase PARAM_* constants have been deprecated, see the in-class documentation for details. Use the equivalent ParamValidator constants instead.
    • The value returned for 'upload'-type parameters has changed from WebRequestUpload to Psr\Http\Message\UploadedFileInterface.
  • Validation of 'user'-type parameters is more flexible. PARAM constants exist to specify the type of "user" allowed and to request UserIdentity objects rather than name strings. The default is to accept all types (name, IP, range, and interwiki) that were formerly accepted.
  • Maximum limits are no longer ignored in "internal mode".
  • The $paramName to ApiBase::handleParamNormalization() should now include the prefix.
  • (task T245931) meta=siteinfo&siprop=interwikimap no longer reports language or extralanglink when $wgInterwikiMagic is false.

Languages updated in 1.35[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 default targets for the ISBN search from Special:BookSources in English have been updated for better international suppport. They will now be BetterWorldBooks.com, OpenLibrary.org and Worldcat.org.
  • (task T237672) Changed the Moroccan Arabic language (ary) to the Arabic script.
  • (task T201269) Added language support for Amis (ami).
  • (task T248299) Added language support for Inari Sami (smn).
  • (task T251369) Added language support for Ladin (lld).
  • (task T251369) Added language support for Seediq (trv), also known as Taroko.

    • Parser::getDefaultPreprocessorClass(), deprecated in 1.34, has been removed.
  • MediaWikiTestCase::prepareServices(), deprecated in 1.32, has been removed
  • The method ContentHandler::getSlotDiffRendererInternal is replaced with ContentHandler::getSlotDiffRendererWithOptions. This breaks consumers which call parent::getSlotDiffRendererInternal (no instances of which are known).

  • WikiPage::selectFields, deprecated in 1.31, was removed. Use ::getQueryInfo.
  • The remaining static methods for MagicWord, deprecated in 1.32, were removed. These were MagicWord::get(), ::getSubstIDs(), ::getDoubleUnderscoreArray(), ::getVariableIDs(), and ::getCacheTTL(). Instead, use MagicWordFactory (via MediaWikiServices).
  • ApiBase::checkTitleUserPermissions no longer accepts a User as the third parameter. Passing a user was deprecated in 1.33.
  • Sanitizer::setupAttributeWhitelist() and Sanitizer::attributeWhitelist(), deprecated in 1.34, have been removed. They should not have been public.

  • EditPage::$hookError was changed from public to private.
  • Title::isValidMoveOperation, ::moveTo, and ::isValidMoveTarget, deprecated in 1.25, were removed. Use the MovePage class and its methods instead.

    • setVary
  • ApiDelete::delete and ::deleteFile, both of which were protected methods, have been made private to allow a signature change.
  • HistoryPager::revLink, ::curLink, ::lastLink, and ::diffButtons, which had no visibilities defined, have been made private to allow signature changes.
  • SpecialNewpages::revisionFromRcResult, which previously was protected, has been made private to allow a signature change.
  • DifferenceEngine::$mOldRev and $mNewRev, deprecated for public access in 1.32, have been removed.
  • DifferenceEngine::revisionDeleteLink, which was previosuly protected, has been made private to allow a signature change.
  • DifferenceEngine::getParserOutput, which is protected, has had a breaking signature change: the second parameter must be a RevisionRecord object, rather than a Revision object.

  • Revision::loadFromId and RevisionStore::loadRevisionFromId have been removed.
  • OutputPage::parserOptions doesn't accept an $options parameter anymore.
  • MessageCache::getParserOptions previously did not have a visibility set. It has been made private.
  • SpecialUndelete::showDiff previously did not have a visibilty set. It hav been made private to allow a signature change.
  • The Skin no longer loads the "mediawiki.legacy.shared" or "mediawiki.legacy.commonPrint" modules. The legacy shared styles must now be loaded by the skin explicitly, either inherited via the "mediawiki.skinning.*" modules, or by making your skin's main styles module use the ResourceLoaderSkinModule class with the "legacy" attribute. See Vector and Monobook for examples.
  • Passing an ApiMain to the constructor of ApiResult is no longer supported. This was deprecated in 1.25.
  • ResourceLoaderWikiModule::invalidateModuleCache has been declared to be @internal as part of a signature change. No known uses exist outside of MediaWiki core.

  • DatabaseBlock::isValid, deprecated in 1.33, was removed.
  • HTMLUserTextField and HTMLUsersMultiselectField previously implied required=true when exists=true. Form fields that use exists=true should also set required=true if they are required.
  • In DatabaseUpdater, the following methods are no longer public: dropTable(), modifyTable(), modifyField(), runMaintenance(), copyFile(), appendLine(). In PostgresUpdater, the following methods are no longer public: addPgEnumValue(), addPgIndex(), addPgExtIndex(). This change was made without deprecation due to immediate danger of data corruption and loss, see task T157651. Extensions should instead use dropExtensionTable(), modifyExtensionExtensionTable(), modifyExtensionField(), addExtensionUpdate(). The addExtensionUpdate() method can still be used to access any of the protected methods on DatabaseUpdater.
  • ResourceLoader no longer provides the (always-true) variables for wgEnableAPI and wgEnableWriteAPI; they were deprecated in MediaWiki 1.31 and removed from the PHP environment in MediaWiki 1.32.
  • The wfSetupSession global function, deprecated in 1.27, was removed. Use the persist() method of the right MediaWiki\Session\SessionManager object instead.
  • The wfIsHHVM global function, deprecated in 1.34, was removed.
  • GenderCache::doTitlesArray no longer accepts string values in its $titles array parameter. Use Title objects (or other LinkTarget) instead.
  • Unused CommentStore::MAX_COMMENT_LENGTH has been removed.
  • User::checkTemporaryPassword() and User::checkPassword(), deprecated in 1.27, were removed. Use AuthManager instead.
  • All constants and class functions now have explicit visibility modifiers. This means, per mw:Stable interface policy, that these should now be considered stable. This also helps MW align with PSR 2 and PSR 12. This was done based on audits of the corpus of skins and extensions hosted in Gerrit. If you find any that you need to be less restrictive (i.e. public or protected), please report these so that we can re-evaluate or suggest workarounds.
  • BaseTemplate::msgWiki(), deprecated in 1.33, was removed. Use ->msg() or ->getMsg() instead.
  • QuickTemplate::msgWiki(), deprecated in 1.33, was removed. Use ->msg() instead.

    • WatchedItemQueryService
    • WatchedItemStore
  • The following classes now require setHookContainer() to be called after construction:
    • AuthenticationProvider
    • ResourceLoaderModule
    • SearchEngine
  • The parameters to ChronologyProtector::getTouched() and ILBFactory::getChronologyProtectorTouched() were changed without backwards compatibility.
  • The deprecated $blacklist parameter to wfIsBadImage() has been removed.
  • SpecialBlock::checkUnblockSelf no longer accepts an integer representing an user ID as part of ongoing refactoring of SpecialBlock class.
  • User::setInternalPassword() and User::setPassword(), deprecated in 1.27, have been removed. Use User::changeAuthenticationData() instead.
  • User::selectFields(), deprecated in 1.31, has been removed. Use User::getQueryInfo() instead.
  • The "legacy" serialization type in RESTBagOStuff, deprecated in 1.34, has been removed.
  • The populateContentModel.php maintenance script was removed. It has been replaced by the populateContentTables.php script.
  • The findHooks.php maintenance script, for the old hooks system, was removed.
  • (task T257278) Calling MediaWiki\Shell\Command::restrict() will now overwrite any previous restrictions rather than adding to them, making it possible to disable the default restrictions.

Deprecations in 1.35[edit]

  • The PHPUnit4And6Compat class, used to provide compatibility with PHPUnit 4, is now deprecated. MediaWiki support for PHPUnit 4 ended with the removal of HHVM support.
  • LockManagerGroup::getDefault() and LockManagerGroup::getAny() are deprecated. They seem to be unused. Just use get() directly, and catch any exception.
  • AbstractBlock::getPermissionsError and AbstractBlock::getBlockErrorParams are deprecated. Use BlockErrorFormatter::getMessage instead.
  • The IP class is deprecated. Please instead use the Wikimedia\IPUtils class from the new wikimedia/ip-utils library instead. Additionally, the RE_IP_* constants are also deprecated. RE_IP_BYTE can be replaced with a class constant on the IPUtils class, while the others will eventually be made private.
  • The following Language methods are deprecated: getFallbackFor, getFallbacksFor, getFallbacksIncludingSiteLanguage. Use the corresponding new methods on the LanguageFallback class: getFirst, getAll, and getAllIncludingSiteLanguage.
  • FileJournal::factory is deprecated. Use the constructor directly instead.
  • AbstractBlock methods setBlocker(), getBlocker() are deprecated and will become internal implementation of DatabaseBlock.
  • Title::countRevisionsBetween has been deprecated and moved into RevisionStore.
  • FileBackendGroup::singleton() is deprecated. Use MediaWikiServices instead.
  • FileBackendGroup::destroySingleton() is deprecated. Test frameworks should instead reset MediaWikiServices between test runs. (MediaWikiIntegrationTestCase does this automatically.)
  • GenderCache::singleton(), deprecated in 1.28, is hard deprecated. Use MediaWikiServices::getGenderCache() instead.
  • MediaWikiIntegrationTest::setContentLang() has been deprecated. Use setMwGlobals( 'wgLanguageCode', 'xxx' ) to set a different site language code, or setService( 'ContentLanguage', $myObj ) to set a specific Language object. Service resets and $wgContLang will be handled automatically.
  • MediaWikiIntegrationTest::assertType() has been deprecated, as part of the work to move to PHPUnit 8; PHPUnit's assertInternalType() was deprecated, and will be removed in PHPUnit 9. MediaWikiIntegrationTest::assertTypeOrValue(), a wrapper for assertType(), has been removed immediately, without deprecation.
  • AbstractBlock::getReason is deprecated, since reasons are actually stored as CommentStoreComments, and getReason returns a string with no caller control over language or formatting. Instead use AbstractBlock::getReasonComment, which returns the CommentStoreComment.
  • The global function wfGetRusage() is deprecated and will now always call the getrusage() function without checking for its existence.
  • The properties User::mBlock, User::mBlockedby and User::mHideName are deprecated. Instead, use User::getBlock to get the block, then use AbstractBlock::getByName or AbstractBlock::getHideName.Use the GetUserBlock hook to set, unset or modify a block, including hiding or unhiding a user.
  • Directly calling the MergeHistory constructor is deprecated. Instead, use the new MergeHistoryFactory class.
  • Language::factory() and Language::getParentLanguage() are deprecated, and so is directly calling the Language constructor. Use the new LanguageFactory class instead.
  • Language::classFromCode() is deprecated. There is no reason it should be used outside the Language class itself.
  • Language::clearCaches() is deprecated. Instead, reset all services and set Language::$mLangObjCache = [].
  • The following functions from Language class are deprecated in favour of respective functions in LanguageConverter:
    • autoConvert
    • autoConvertToAllVariants
    • convert
    • convertTitle
    • convertNamespace
    • hasVariants
    • hasVariant
    • convertHtml
    • convertCategoryKey
    • getVariants
    • getPreferredVariant
    • getURLVariant
    • findVariantLink
    • getExtraHashOptions
    • updateConversionTable
  • Language::classFromCode() is hard deprecated and should be removed in 1.36
  • Language::getConverter() is deprecated and should be removed in 1.36
  • Language::MESSAGES_FALLBACKS, Language::STRICT_FALLBACKS were deprecated. Use LanguageFallback::MESSAGES and LanguageFallback::STRICT respectively
  • Language::$mLangObjCache is deprecated and should be removed in 1.36. Use MediaWikiServices instead to get a LanguageFactory.
  • Language::getMessagesFor(), getMessageFor(), and getMessageKeysFor() are deprecated. Use LocalisationCache's getItem(), getSubitem(), and getSubitemList() methods directly.
  • OutputPage::getCSPNonce() is deprecated, use OutputPage::getCSP()->getNonce() instead.
  • DerivedPageDataUpdater::prepareUpdate accepted as its second parameter an optional array of options. Specifying the value of the `oldrevision` key of the array to be a Revision object, rather than a RevisionRecord object, is hard deprecated. The same applies to the options parameter in WikiPage::doEditUpdates.
  • Skin::makeI18nUrl() and makeNSUrl() have been deprecated, no longer used.
  • Title::countAuthorsBetween and Title::getAuthorsBetween were hard deprecated. Use respective methods in RevisionStore instead.
  • Remove deprecated SkinCopyrightFooter &$forContent parameter
  • The following Language class static variables have been replaced with constants and deprecated: $mWeekdayMsgs, $mWeekdayAbbrevMsgs, $mMonthMsgs, $mMonthGenMsgs, $mMonthAbbrevMsgs, $mIranianCalendarMonthMsgs, $mHebrewCalendarMonthMsgs, $mHebrewCalendarMonthGenMsgs, $mHijriCalendarMonthMsgs and $durationIntervals.
  • As part of dropping security support for IE 6 and IE 7, WebRequest::checkUrlExtension() has been deprecated, and now always returns true.
  • The following ApiBase::PARAM_* constants have been deprecated in favor of equivalent ParamValidator constants: PARAM_DFLT, PARAM_ISMULTI, PARAM_TYPE, PARAM_MAX, PARAM_MAX2, PARAM_MIN, PARAM_ALLOW_DUPLICATES, PARAM_DEPRECATED, PARAM_REQUIRED, PARAM_SUBMODULE_MAP, PARAM_SUBMODULE_PARAM_PREFIX, PARAM_ALL, PARAM_EXTRA_NAMESPACES, PARAM_SENSITIVE, PARAM_DEPRECATED_VALUES, PARAM_ISMULTI_LIMIT1, PARAM_ISMULTI_LIMIT2, PARAM_MAX_BYTES, PARAM_MAX_CHARS.
  • ApiBase::explodeMultiValue() is deprecated. Use ParamValidator::explodeMultiValue() instead.
  • ApiBase::parseMultiValue() is deprecated. No replacement is provided; generally this sort of thing should be handled by fully validating the parameter.
  • ApiBase::validateLimit() and ApiBase::validateTimestamp() are deprecated. Use ApiParamValidator::validateValue() with an appropriate settings array instead.
  • ContentHandler (use ContentHandlerFactory):
    • getForTitle
    • getForContent
    • getForModelID
    • getContentModels
    • getAllContentFormats
    • protected $handler (not need anymore)
    • cleanupHandlersCache (not need anymore)
  • (task T212738) The $wgVersion global is deprecated; instead, use MW_VERSION.
  • $wgMemc is deprecated, use MediaWikiServices::getLocalServerObjectCache() instead.
  • ObjectCache::detectLocalServerCache() is deprecated, instead use MediaWikiServices::getLocalServerObjectCache() or ObjectCache::makeLocalServerCache().
  • ImagePage::getImageLimitsFromOptions() is deprecated. Use static function MediaFileTrait::getImageLimitsFromOptions() instead.
  • As part of work to replace the Parser, alongside the breaking changes listed above, a large number of deprecations changes been made, to simplify the API or because they will not be supported in replacement:
    • Parser::doBlockLevels() (and BlockLevelPass class has been marked @internal)
    • Parser::setFunctionTagHook()
    • Parser::attributeStripCallback()
    • Parser::fetchTemplate() - use Parser::fetchTemplateAndTitle() instead.
    • Parser::enableOOUI() - use $parser->getOutput()->enableOOUI() instead.
    • LinkHolderArray has been deprecated for public usage and will be internal part of parser.
    • The following parser-related hooks have been deprecated:
    • The accessor/mutator methods Parser::Options(), Parser::OutputType(), and Parser::Title() have been deprecated; use the appropriate Parser::get* or Parser::set* methods instead.
    • Parser::firstCallInit() has been deprecated. The parser is initialized fully on construction and so ::firstCallInit() no longer has any effect when manually invoked.
    • ParserOptions::setAllowExternalImages(), ::setAllowExternalImagesFrom(), and ::setEnableImageWhitelist() have been deprecated. Future parsers will not allow per-parser configuration of image filtering; use site configuration instead.
