= MediaWiki 1.37 = == MediaWiki 1.37.0-PRERELEASE == THIS IS NOT A RELEASE YET MediaWiki 1.37 is an alpha-quality development branch, and is not recommended for use in production. == Upgrading notes for 1.37 == Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed per-version upgrade instructions from the oldest supported upgrading version, MediaWiki 1.27. Some specific notes for MediaWiki 1.37 upgrades are below: * (T280806) Deprecated methods of fetching API tokens have been removed. This may cause older bots and scripts to fail. Most queries are trivially updateable to using new methods. See the Action API changes section below for more information. * … For notes on 1.36.x and older releases, see HISTORY. === Configuration changes for system administrators in 1.37 === * (T242768) The PasswordCannotMatchUsername password policy has been removed, please use PasswordCannotBeSubstringInUsername instead. If you have not customised your password policies, there will be nothing to do here. * … ==== New configuration ==== * $wgBrowserFormatDetection - This setting allows the enabling or disabling of automatic detection of possible phone numbers in a webpage in Safari on iOS. * … ==== Changed configuration ==== * $wgContentHandlerTextFallback - This setting, which defines how to react if a plain text version of a non-text Content object is requested using ContentHandler::getContentText(), is deprecated. * $wgActions was reworked to support injecting dependencies into Action subclasses. Previously, $wgActions was an array where the keys were the names of actions, and the values had the following impacts (for a given key 'Foo') - `true`: use the class 'FooAction' unless for a specific page WikiPage::getActionOverrides() wants to override that action - a string: use the class with that name, and do not allow overriding on a per-page basis - `false`: the action is disabled - a callable: use the Action instance returned by invoking that callback, and do not allow overriding on a per-page basis - an object: use that specific Action instance, and do not allow overriding on a per-page basis. As part of T253078, values can now be arrays that are not callables, which are treated as ObjectFactory specs, allowing for services to be injected. Additionally, the distinction between values that allow per-page overrides and those that do not was removed - all actions can now be overridden on a per-page basis using WikiPage::getActionOverrides(). * $wgShellboxUrl is deprecated, use $wgShellboxUrls as a mapping of service => URL instead. * $wgIncludejQueryMigrate Default value for this configuration has changed from true to false. This may break gadgets that depended on methods removed in jQuery 3. See T280944 for more information. * $wgMimeTypeBlacklist - This configuration array now prohibits the RFC 4329 form of JavaScript, 'application/javascript', as well as previous MIME types. * A number of settings have been renamed. The former configuration variable names are deprecated, but will be used as the fall back if they are still set, and remain temporarily available for extensions which try to read them: - $wgFileBlacklist is now $wgProhibitedFileExtensions - $wgMimeTypeBlacklist is now $wgMimeTypeExclusions - $wgEnableUserEmailBlacklist is now $wgEnableUserEmailMuteList - $wgShortPagesNamespaceBlacklist is now $wgShortPagesNamespaceExclusions * $wgFragmentMode - Default value of this variable has changed from legacy-first to html5-first: both the HTML5 anchor and the legacy percent-encoding-style anchor will still be generated for section titles, but references to them will use the HTML5 version, resulting in human-readable fragments. * … ==== Removed configuration ==== * $wgLegacyJavaScriptGlobals, deprecated in 1.36. * $wgShowDBErrorBacktrace, deprecated and non-functional since 1.32. * $wgShowSQLErrors, deprecated and non-functional since 1.32. * $wgLangObjCacheSize - The LanguageFactory service now always retains at most 10 objects in its LRU-cache. * (T274695) $wgAjaxEditStash, deprecated in 1.36. * $wgDjvuToXML, without deprecation because it is obsolete and abandoned upstream. Use $wgDjvuDump instead. * … === New user-facing features in 1.37 === * (T161934) MediaWiki now supports JPEG2000 files, to a limited extent. * Media files uploaded server side using the importImages.php maintenance script now have the "mw-server-side-upload" change tag. * … === New developer features in 1.37 === * … === External library changes in 1.37 === * … ==== New external libraries ==== * Added symfony/polyfill-php80 1.23.1. * Added whatwg-fetch 3.6.2. * Added wikimedia/normalized-exception 1.0.1. * … ===== New development-only external libraries ===== * … ==== Changed external libraries ==== * Updated OOjs from v5.0.0 to v6.0.0 * Updated OOjs-Router from v0.2.0 to v0.3.0 * Updated OOUI from v0.41.3 to v0.42.0 * Updated WVUI from v0.1.0 to v0.3.0 * Updated cssjanus/cssjanus from v1.3.0 to v2.1.0. * Updated psr/container from v1.0.0 to v1.1.1. * Updated wikimedia/minify from v2.2.2 to v2.2.4. * Updated wikimedia/object-factory from v3.0.0 to v3.0.2. * Updated wikimedia/parsoid from v0.13.0-a20 to v0.14.0-a1. * Updated wikimedia/relpath from v2.1.1 to v3.0.0. * Updated wikimedia/remex-html from v2.3.1 to v2.3.2. * Updated wikimedia/shellbox from v1.0.4 to v2.0.0. * Updated wikimedia/wait-condition-loop from v2.0.1 to v2.0.2. * … ===== Changed development-only external libraries ===== * Updated qunit from 2.10.0 to 2.16.0. * … ==== Removed external libraries ==== * The pimple/pimple development-only library has been removed. * … === Bug fixes in 1.37 === * … === Action API changes in 1.37 === * (T280806) The API methods for fetching tokens which were deprecated in MediaWiki 1.24 have been removed. action=query&meta=tokens&type= should be used instead. Please note some token types no longer exist, and you should just use type=csrf for those instead. - action=query&prop=info&intoken -> action=query&meta=tokens&type=csrf - action=tokens&type= -> action=query&meta=tokens&type= - action=query&list=recentchanges&rctoken -> action=query&meta=tokens&type=csrf - action=query&prop=revisions&rvtoken=rollback -> action=query&meta=tokens&type=rollback - action=query&meta=userinfo&uiprop=preferencestoken -> action=query&meta=tokens&type=csrf - action=query&list=users&ustoken=userrights -> action=query&meta=tokens&type=userrights * … === Action API internal changes in 1.37 === * … === Languages updated in 1.37 === MediaWiki supports over 350 languages.

The Revision object has been removed from the arrays, and the 'revision-record' key should be used to get the relevant RevisionRecord instead: - PageUpdater::doCreate() - PageUpdater::doModify() - Parser::statelessFetchTemplate() - WikiPage::doEditContent() The ParserOptions `templateCallback` option is a callback that is called in Parser::fetchTemplateAndTitle() and should return an array - the 'revision' key to that array used to be a Revision object and was used if no 'revision-record' was returned - it is now ignored. * Previously, the classes RevisionTestModifyableContent and RevisionTestModifyableContentHandler were loaded for use in tests, but were only used within the tests for the since-removed Revision class.

Now, $wgUser is not updated, and if no performer is specified the reusable TestUser object for the sysop is relied on.
