== MediaWiki 1.32 == THIS IS NOT A RELEASE YET MediaWiki 1.32 is an alpha-quality branch and is not recommended for use in production. === Configuration changes in 1.32 === ==== New configuration ==== * $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. (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. ==== Changed configuration ==== * $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. (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. ==== Removed configuration ==== * $wgEnableAPI and $wgEnableWriteAPI – These settings, deprecated in 1.31, have been removed. (T115414) * $wgSiteSupportPage – This setting, unused since 1.5, was removed. * $wgBrowserBlacklist – This setting, deprecated in 1.30, was removed. * $wgExperimentalHtmlIds – This setting, deprecated since 1.30, was removed. The 'html5-legacy' value for $wgFragmentMode is no longer accepted. * $wgPasswordSenderName - This setting, ignored since 1.23 by MediaWiki and most extensions, is no longer set. Instead, you can modify the system message `emailsender`. * $wgTidyConfig – The experimental Html5Internal and Html5Depurate tidy drivers were removed. RemexHtml, which is the default, should be used instead. === New features in 1.32 === * (T112474) Generalized the ResourceLoader mechanism for overriding modules using a particular page during edit previews. * (T12331) You can now log page creation events by setting $wgPageCreationLog to true. * Added 'ApiParseMakeOutputPage' hook. * (T174313) Added checkbox on Special:ListUsers to display only users in temporary user groups. * (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. * (T194950) Added 'ApiMaxLagInfo' hook. * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when reauthenticating. * 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 . * (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. * (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. === External library changes in 1.32 === ==== New external libraries ==== * Added wikimedia/xmp-reader 0.6.0 * … ==== Changed external libraries ==== * Updated qunitjs from 2.4.0 to 2.6.2. * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0. ** ScopedCallback objects can no longer be serialized. * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1. * Updated mediawiki/mediawiki-codesniffer from v20.0.0 to v21.0.0. * Updated composer/spdx-licenses from 1.3.0 to 1.4.0. * Updated jquery.i18n from 1.0.4 to 1.0.5. * Updated wikimedia/timestamp from 1.0.0 to 2.0.0. * Updated wikimedia/remex-html from 1.0.3 to 2.0.0. * Updated jquery from v3.2.1 to v3.3.1. ==== Removed external libraries ==== * … === Bug fixes in 1.32 === * SpecialPage::execute() will now only call checkLoginSecurityLevel() if getLoginSecurityLevel() returns non-false. === Action API changes in 1.32 === * 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. * (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). * (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. === Action API internal changes in 1.32 === * Added 'ApiParseMakeOutputPage' hook. * Parameter names may no longer contain '{' or '}', as these are now used for templated parameters. * (T194950) Added 'ApiMaxLagInfo' hook. * Added 'ApiParseMakeOutputPage' hook. * The following methods now take a RevisionRecord rather than a Revision. No external callers are known. * ApiFeedContributions::feedItemAuthor() * ApiFeedContributions::feedItemDesc() * ApiQueryRevisionsBase::extractRevisionInfo() === Languages updated in 1.32 === 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. * (T193566) Added language support for Ambonese Malay (abs). * (T194047) Added language support for Shawiya, Latin script (shy-latn). * (T195940) Added language support for Batak Mandailing (btm). * (T137491) Added language support for Standard Moroccan Amazigh (zgh). * (T198132) Added language support for Manipuri (mni). * (T201276) Added language support for Western Armenian (hyw). * (T201583) Added language support for Mon (mnw). === Breaking changes in 1.32 === * $wgRequestTime, deprecated in 1.25, was removed. Use $_SERVER['REQUEST_TIME_FLOAT'] or WebRequest::getElapsedTime() instead. * The MediaWikiI18N class, deprecated in 1.31, was removed. * QuickTemplate::setTranslator(), deprecated in 1.31, was removed. Use Skin::msg() instead. * wfInitShellLocale(), deprecated in 1.30, was removed. * wfShellExecDisabled(), deprecated in 1.30, was removed. * The type string for the parameter $lang of DateFormatter::getInstance, deprecated in 1.31, was removed. * The EDIT_TOKEN_SUFFIX constant deprecated in 1.27, was removed. Use MediaWiki\Session\Token::SUFFIX instead. * EditPage::isOouiEnabled() deprecated in 1.30, was removed. * mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl() instead. * (T61113) The following methods and constants from the Revision class, which were deprecated in 1.25, have now been removed: * Revision::getRawUser() * Revision::getRawUserText() * Revision::getRawComment() * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use mw.msg() or mw.message() instead. * mw.util.escapeId(), deprecated in 1.30, was removed. Use mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead. * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use jquery.accessKeyLabel instead. * The SqlDataUpdate class, deprecated in 1.28, has been removed. * The Html5Internal and Html5Depurate tidy driver classes were removed, along with the Balancer tidy implementation. Both implementations were experimental, and were replaced by RemexHtml. * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both removed. Use JobQueueGroup::singleton()->push() instead. * The jquery.footHovzer module, for mediawiki.debug, was removed. * The es5-shim module, empty and deprecated since 1.29, was removed. * the dom-level2-shim module, empty and deprecated since 1.29, was removed. * the json module, empty and deprecated since 1.29, was removed. * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was removed. Use mediawiki.widgets.visibleLengthLimit instead. * The jquery.farbtastic module, unused since 1.18, was removed. * The 'jquery.expandableField' module, unused since 1.22, was removed. * (T181318) The $wgStyleVersion setting and its appendage to various script and style URLs in OutputPage, deprecated in 1.31, was removed. * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide any HTMLForm object rather than PreferencesForm. * The non namespaced TimestampException class, deprecated in 1.29, was removed. Use Wikimedia\Timestamp\TimestampException instead. * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence, utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed. The UtfNormal\Utils class from the utfnormal library should be used instead. * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants from the UtfNormal\Constants class from the utfnormal library should be used * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed from ResourceLoader. Instead, use `@import` statements in LESS to import files directly from nearby directories within the same project. * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated since 1.30, was removed. Instead, to expose variables from PHP to LESS, use the ResourceLoaderModule::getLessVars() method. * 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. * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30, were removed. Use the ParserCache class instead. * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback instead. * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(), deprecated since 1.26, was removed. Use getDefinitionSummary() instead. * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump" and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump" is no longer loaded by default. The Vector and MonoBook skins have made a minor change to implement the toggle feature with CSS instead. To restore prior functionality, either explicitly load "jquery.mw-jump" in your skin or refer to T195256 for details on how to make the same change. * Hook 'EditPageBeforeEditChecks' was removed; use 'EditPageGetCheckboxesDefinition' instead. * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since 1.28, were removed. LinkRenderer::getLinkClasses() should be used instead. * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode() instead. * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of CapsuleMultiselectWidget. The following methods may no longer be used: * setItemsFromData: Use setValue instead * getItemsData: Use getItems instead and get the data property * 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. * 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. Define $wgProfiler via LocalSettings.php instead. === Deprecations in 1.32 === * 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. * CollationFa has been removed completely as it's not needed anymore * 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.watch, 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. * (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. * (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. * (T194263) ContentHandler::makeParserOptions() is deprecated. Use WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead. * (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. * (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. * (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. * (T197179) Parameters 'notice', 'notice-messages', 'notice-message', previously used by OOUI HTMLForm fields, are now deprecated. Use 'help', 'help-message', 'help-messages' instead. * (T197179) HTMLFormField::getNotices() is now deprecated. * The jquery.localize module is now deprecated. Use jquery.i18n instead. === Other changes in 1.32 === * (T198811) The following tables have had their UNIQUE indexes turned into proper PRIMARY KEYs for increased maintainability: interwiki, page_props, protected_titles and site_identifiers. * OOUI HTMLForm will now display help text inline after the input field, rather than in a popup. Previous behavior can be restored by using `'help-inline' => false`. * The archive table's ar_rev_id field is now unique. * Special:BotPasswords now requires reauthentication. * … == Compatibility == MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 7.0.0 or later for long term support. 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) == Upgrading == 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 == Documentation for both end-users and site administrators is available on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain): https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation == Mailing list == A mailing list is available for MediaWiki user support and discussion: https://lists.wikimedia.org/mailman/listinfo/mediawiki-l A low-traffic announcements-only list is also available: https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce 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. == IRC help == There's usually someone online in #mediawiki on irc.freenode.net.
