= MediaWiki release notes = Security reminder: MediaWiki does not require PHP's register_globals. If you have it on, turn it '''off''' if you can. == MediaWiki 1.22.8 == This is a security and maintenance release of the MediaWiki 1.22 branch. === Changes since 1.22.7 === * (bug 65839) SECURITY: Prevent external resources in SVG files. * (bug 66428) MimeMagic: Don't seek before BOF. This has weird side effects like only extracting the tail of the file partially or not at all. == MediaWiki 1.22.7 == This is a security and maintenance release of the MediaWiki 1.22 branch. === Changes since 1.22.6 === * (bug 65501) SECURITY: Don't parse usernames as wikitext on Special:PasswordReset. * (bug 36356) Add space between two feed links. * (bug 63269) Email notifications were not correctly handling the [[MediaWiki:Helppage]] message being set to a full URL. This is a regression from the 1.22.5 point release, which made the default value for it a URL. If you customized [[MediaWiki:Enotif body]] (the text of email notifications), you'll need to edit it locally to include the URL via the new variable $HELPPAGE instead of the parser functions fullurl and canonicalurl; otherwise you don't have to do anything. * Add missing uploadstash.us_props for PostgreSQL. * (bug 56047) Fixed stream wrapper in PhpHttpRequest. == MediaWiki 1.22.6 == This is a security release of the MediaWiki 1.22 branch. === Changes since 1.22.5 === * (bug 63251) SECURITY: Escape sortKey in pageInfo. == MediaWiki 1.22.5 == This is a security and maintenance release of the MediaWiki 1.22 branch. === Changes since 1.22.4 === * (bug 62497) SECURITY: Add CSRF token on Special:ChangePassword. * (bug 62467) Set a title for the context during import on the cli. * Fix custom local MediaWiki:Helppage values. * mediawiki.js: Fix documentation breakage. * (bug 58153) Make MySQLi work with non standard port. * (bug 53887) Reintroduced a link to help pages in the default sidebar, that any sysop can customize by editing [[MediaWiki:Sidebar]] locally. The link now points to a mediawiki.org page which is guaranteed to exist. Nothing needs to be done on your end, but remember to adjust [[MediaWiki:Sidebar]] for the needs of your wikis. Everyone can help with the shared documentation by translating: https://www.mediawiki.org/wiki/Special:Translate/agg-Help_pages . * (bug 53888) Corrected a regression in 1.22 which introduced red links on the login page. If you previously installed 1.22.x and have created a local page to make the red link blue, write its title as in [[MediaWiki:helplogin-url]] if you didn't already. Otherwise, you don't need to do anything, but you can translate the help page at https://www.mediawiki.org/wiki/Help:Logging_in . == MediaWiki 1.22.4 == This is a maintenance release of the MediaWiki 1.22 branch. === Changes since 1.22.3 === * Use the correct branch of the extensions' git repositories. == MediaWiki 1.22.3 == This is a security and bugfix release of the MediaWiki 1.22 branch. === Changes since 1.22.2 === * (bug 60771) SECURITY: Disallow uploading SVG files using non-whitelisted namespaces. Also disallow iframe elements. User will get an error including the namespace name if they use a non- whitelisted namespace. * (bug 61346) SECURITY: Make token comparison use constant time. It seems like our token comparison would be vulnerable to timing attacks. This will take constant time. * (bug 61362) SECURITY: API: Don't find links in the middle of api.php links. * (bug 53710) Add sequence support for upsert in DatabaseOracle in the same way as in selectInsert * (bug 60231, 58719) Various fixes to job running code in Wiki.php: Make it async on Windows. Fixed possible "invalid filename" errors on Windows. Redirect output to dev/null to avoid hanging PHP. * (bug 60083) Correct sequence name for fresh Postgres installation. Spotted by gebhkla * (bug 60531) Avoid variable naming conflicts in DatabasePostgres::selectSQLText. Spotted by gebhkla * (bug 60094) Fix rebuildall.php fatal error with PostgreSQL. The fix for 47055 introduced a fatal error when running rebuildall.php. This is a workaround suggested by gebhkla on Bugzilla. It just checks to make sure $options is actually an array before calling array_search on it. * (bug 43817c12) Add error handling if descriptionmsg isn't defined for extension. * (bug 60543) Special:PrefixIndex omits stripprefix=1 for "Next page" link. == MediaWiki 1.22.2 == This is a security and bugfix release of the MediaWiki 1.22 branch. === Changes since 1.22.1 === * (bug 60339) SECURITY: Sanitize shell arguments to DjVu files, and other media formats. * (bug 58253) Check for very old PCRE versions in installer and updater. * (bug 60054) Make WikiPage::$mPreparedEdit public. == MediaWiki 1.22.1 == This is a security and maintenance release of the MediaWiki 1.22 branch. === Changes since 1.22.0 === * (bug 57550) SECURITY: Disallow stylesheets in SVG Uploads * (bug 58088) SECURITY: Don't normalize U+FF3C to \ in CSS Checks * (bug 58472) SECURITY: Disallow -o-link in styles * (bug 58553) SECURITY: Return error on invalid XML for SVG Uploads * (bug 58699) SECURITY: Fix RevDel log entry information leaks * (bug 58178) Restore compatibility with curl < 7.16.2. * (bug 56931) Updated the plural rules to CLDR 24. They are in new format which is detailed in UTS 35 Rev 33. The PHP parser and evaluator as well as the JavaScript evaluator were updated to support the new format. Plural rules for some languages have changed, most notably Russian. Affected software messages have been updated and marked for review at translatewiki.net. This change is backported from the development branch of MediaWiki 1.23. * (bug 58434) The broken installer for database backend Oracle was fixed. * (bug 58167) The web installer no longer throws an exception when PHP is compiled without support for MySQL yet with support for another DBMS. * (bug 58640) Fixed a compatibility issue with PCRE 8.34 that caused pages to appear blank or with missing text. * (bug 47055) Changed FOR UPDATE handling in Postgresql * (bug 57026) Avoid extra parsing in prepareContentForEdit() == MediaWiki 1.22.0 == MediaWiki 1.22.0 is the stable branch and is recommended for use in production. MediaWiki 1.22.0 is a large release that contains many new features and bug fixes. * Breaking Changes in 1.22.0 * New features in 1.22.0 * Configuration changes in 1.22.0 * Bug fixes in 1.22.0 * API changes in 1.22.0 * Languages updated in 1.22.0 * Other changes in 1.22.0 === Breaking Changes in 1.22.0 === * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also change their class name from .editsection to .mw-editsection and place them at the end of the heading element instead of the beginning. Client-side code and screen-scrapers will have to be adjusted to handle both cases (old HTML will still be visible on cached page renders until they are purged); extensions using the DoEditSectionLink or EditSectionLink hooks might need adjustments as well. * (bug 55818) BREAKING CHANGE: Removed undocumented 'Debug' hook in wfDebug. This resolves an infinite loop when using $wgDebugFunctionEntry = true. * BREAKING CHANGE: action=parse no longer returns all langlinks for the page with prop=langlinks by default. The new effectivelanglinks parameter will request that the LanguageLinks hook be called to determine the effective language links. * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not apply the new LanguageLinks hook, and thus only consider language links stored in the database. * BREAKING CHANGE: Implementation of MediaWiki's JS and JSON value encoding has changed: ** MediaWiki no longer supports PHP installations in which the native JSON extension is missing or disabled. ** XmlJsCode objects can no longer be nested inside objects or arrays. (For Xml::encodeJsCall(), this individually applies to each argument.) ** The sets of characters escaped by default, along with the precise escape sequences used, have changed (except for the Xml::escapeJsString() function, which is now deprecated). * BREAKING CHANGE: The Services_JSON class has been removed. If necessary, be sure to upgrade affected extensions at the same time (e.g. Collection). * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and LegacyTemplate classes that supported them were removed as well and are now a part of the Nostalgia extension. * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along with its associated globals of $wgExternalAuthType, $wgExternalAuthConf, $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to use AuthPlugin for external authentication/authorization needs. * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the accesskey character is now $6 instead of $5. * BREAKING CHANGE: meta keywords are no longer supported. A . * (bug 8480) Allow handler specific parameters in galleries (like page number) * jquery.client: Add detection for Opera 15 and Internet Explorer 11. * Change tags (used by the AbuseFilter extension) are now shown on diff pages. * Change tag lists (shown on recent changes, watchlist, user contributions, history pages, diff pages) now include a link to Special:Tags to distinguish them from edit summaries. * Added a new method and hook, User::isEveryoneAllowed() and UserIsEveryoneAllowed, for use in situations where a "does everyone have this right?" check is used to avoid more expensive checks. * (bug 14431) Display "(No difference)" instead of an empty diff (when comparing revisions in the history or when previewing changes while editing). * New hook 'IsUploadAllowedFromUrl' is added which can be used to intercept uploads by URL, useful for blacklisting specific URLs * (bug 21912) Watchlist token implementation has been refactored and Special:ResetTokens was added to allow users to reset their tokens instead of presenting them in Preferences. * Special:PrefixIndex now lets you strip the searched prefix from the displayed titles. Given a list of articles named Bug1, Bug2, you can now transclude the list of bug numbers using: {{Special:PrefixIndex/Bug|stripprefix=1}}. The special page form received a new checkbox matching that option. * (bug 23580) Implement javascript callback interface "mw.hook". * (bug 30713) New mw.hook "wikipage.content". * (bug 40430) jquery.placeholder gets a new parameter to set the attribute value to be used. * $wgHTCPMulticastRouting renamed $wgHTCPRouting since it accepts unicast. * $wgHTCPRouting rules can now be passed an array of hosts/ports to send purge too. Can be used whenever several multicast group could be interested by a specific purge. * (bug 25931) Add Special:RandomInCategory. * mediawiki.util: addPortletLink now supports passing a jQuery object as nextnode. * can now be used inside WikiText. * WebResponse::setcookie is much more featureful. Callers using PHP's setcookie() or setrawcookie() should begin using this instead. * New hook WebResponseSetCookie, called from WebResponse::setcookie(). * New hook ResetSessionID, called when the session id is reset. * Add a mode parameter to tag with potential options of "traditional", "nolines", "packed", "packed-overlay", or "packed-hover". * (bug 47399) A success message is now displayed after changing the password. * Make thumb.php give HTTP redirects for file redirects * (bug 30607) Special:ListFiles can now show old versions of files. Additionally Special:AllMyUploads was introduced so the user can get a list of all things they have ever uploaded, even if it was subsequently overriden. * Introduced Special:MyFiles and Special:AllMyFiles as an alias for Special:MyUploads and Special:AllMyUploads respectively. * IPv6 addresses in X-Forwarded-For headers are now normalised before checking against allowed proxy lists. * Add deferrable update support for callback/closure. * Add TitleMove hook before page renames. * Revision deletion backend code is moved out of SpecialRevisiondelete * Added {{REVISIONSIZE}} variable to get the current size of a revision. * Add support for the LESS stylesheet language to ResourceLoader. LESS is a stylesheet language that compiles into CSS. ResourceLoader file modules may include LESS style files; ResourceLoader will compile these files into CSS before sending them to the client. ** The $wgResourceLoaderLESSVars configuration variable is an associative array mapping variable names to string CSS values. These variables are considered declared for all LESS files. Additional variables may be registered by adding keys to the array. ** $wgResourceLoaderLESSFunctions is an associative array of custom LESS function names to PHP callables. See for more details regarding custom functions. ** $wgResourceLoaderLESSImportPaths is an array of file system paths. Files referenced in LESS '@import' statements are looked up here first. * ResourceLoader supports hashes as module cache invalidation trigger (instead of or in addition to timestamps). * Added $wgExtensionEntryPointListFiles for use in mergeMessageFileList.php. * Added a hook, APIQuerySiteInfoStatisticsInfo, to allow extensions to modify the output of the API query meta=siteinfo&siprop=statistics * Primary keys have been added to both the archive table and the externallinks tables. * Added $wgEnableParserLimitReporting to control whether the NewPP limit report is output in a HTML comment. * The 'UnwatchArticle' and 'WatchArticle' hooks now support a Status object instead of just a boolean return value to abort the hook. * Added a hook, SpecialWatchlistGetNonRevisionTypes, to allow extensions with custom recentchanges entries to hook into the Watchlist without clobbering each other. * A hidden, empty input field was added to the edit form, and any edit that fills it in will be rejected. This prevents against the simplest form of spambots. Previously in the "SimpleAntiSpam" extension by Ryan Schmidt. * populateRevisionLength.php maintenance script updated to also populate archive.ar_len field. * (bug 43571) DatabaseMySQLBase learned to list views, optionally filtered by a prefix. Also fixed PHPUnit test suite when using a MySQL backend containing views. === Configuration changes in 1.22.0 === * $wgRedirectScript was removed. It was unused. * Removed $wgLocalMessageCacheSerialized, it is now always true. * $wgVectorUseIconWatch is now enabled by default. * $wgCascadingRestrictionLevels was added. * ftps, ssh, sftp, xmpp, sip, sips, tel, sms, bitcoin, magnet, urn, and geo have been whitelisted inside of $wgUrlProtocols. * $wgDocType and $wgDTD have been removed and are no longer used for the DOCTYPE. * $wgHtml5 is no longer used by core. Setting it to false will no longer disable HTML5. It is still set to true for extension compatibility but doing so in extensions is deprecated. * $wgXhtmlDefaultNamespace is no longer used by core. Setting it will no longer change the xmlns used by MediaWiki. Reliance on this variable by extensions is deprecated. * $wgHandheldStyle was removed. * $wgHandheldForIPhone was removed. * $wgJsMimeType is no longer used by core. Most usage has been removed since HTML output is now exclusively HTML5. * $wgDBOracleDRCP added. True enables persistent connection with DRCP on Oracle. * $wgLogAutopatrol added to allow disabling logging of autopatrol edits in the logging table. default for $wgLogAutopatrol is true. * The 'edit' right no longer allows for editing a user's own CSS and JS. * New rights 'editmyusercss', 'editmyuserjs', 'viewmywatchlist', 'editmywatchlist', 'viewmyprivateinfo', 'editmyprivateinfo', and 'editmyoptions' restrict actions that were formerly allowed by default. They have been added to the default for $wgGroupPermissions['*']. * The 'editprotected' right no longer allows bypassing of all page protection restrictions. Any group using it for this purpose will now need to have all the individual rights listed in $wgRestrictionTypes for the same effect. * The 'protect' and 'autoconfirmed' rights are no longer used for the default page protection levels. The rights 'editprotected' and 'editsemiprotected' are now used for this purpose instead. * (bug 40866) wgOldChangeTagsIndex removed. * $wgNoFollowDomainExceptions now only matches entire domains. For example, an entry for 'bar.com' will still match 'foo.bar.com' but not 'foobar.com'. * $wgCopyUploadTimeout and $wgCopyUploadAsyncTimeout added to change the timeout times for fetching the file during upload by url. * New key added to $wgGalleryOptions - $wgGalleryOptions['mode'] to set default gallery mode. * New hook 'GalleryGetModes' to allow extensions to make new gallery modes. * The checkbox for staying in HTTPS displayed on the login form when $wgSecureLogin is enabled has been removed. Instead, whether the user stays in HTTPS will be determined based on the user's preferences, and whether they came from HTTPS or not. * $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort, and $wgRC2UDPPrefix configuration options have been deprecated in favor of a $wgRCFeeds configuration array. $wgRCFeeds makes both the format and destination of recent change notifications customizable, and allows for multiple destinations to be specified. * (bug 53862) portal-url, currentevents-url and helppage have been removed from the default Sidebar. * The 'vector-simplesearch' preference is now enabled by default. Previously it was only enabled if the Vector extension was installed. * The precise format of metric datagrams produced by the UDP profiler and stats counter may now be specified as $wgUDPProfilerFormatString and $wgStatsFormatString, respectively. * (bug 54597) $wgBlockOpenProxies, $wgProxyPorts, $wgProxyScriptPath, and $wgProxyMemcExpiry have been removed, along with the open proxy scanner script they were added for. * Default value of $wgMaxShellMemory has been tripled (it's now 300 MB). === Bug fixes in 1.22.0 === * (bug 47271) $wgContentHandlerUseDB should be set to false during the upgrade * Disable Special:PasswordReset when $wgEnableEmail is false. Previously one could still navigate to the page by entering the URL directly. * (bug 47138) Fixed a fatal error when a blocked user tries to automatically create an account on login due external authentication in some circumstances. * (bug 23393) HTML headings containing line breaks are now handled correctly. * (bug 45803) Whitespace within == Headline == syntax and within headings is now non-significant and not preserved in the HTML output. * (bug 47218) Special:BlockList now handles correctly user names with spaces when passed as subpage. * Pager's properly validate which fields are allowed to be sorted on. * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well. Support for Mac "option" was added in 1.16, but the regex was never updated. * (bug 46768) Usernames of blocking users now display correctly, even if numeric. * (bug 39590) Self-transclusions now show the most up to date result always after save instead of being a revision behind. * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated strings will now start with digits 0 and 8-f as often as they should. * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes. * (bug 41545) Allow , , and to be nested like allowed in html. * PLURAL magic word no longer causes a PHP notice when no matching form exists. * (bug 36641) Patrol page links no longer show on non-existent revisions. * (bug 35810) Pages not linked from Special:RecentChanges or Special:NewPages are patrollable now. * (bug 30213) JavaScript for search suggestions is now disabled when the API is disabled, and AJAX patrolling and watching are now disabled when use of the write API is not allowed. * (bug 48294) API: Fix chunk upload async mode. * (bug 46749) Broken files tracking category removed from pages if an image with that name is uploaded. * (bug 14176) System messages that are empty were previously incorrectly treated as non-existent, causing a fallback to the default. This stopped users from overriding system messages to make them blank. * (bug 48319) action=parse no longer returns an error if passed none of 'oldid', 'pageid', 'page', 'title', and 'text' (e.g. if only passed 'summary'). A warning will instead be issued if 'title' is non-default, unless no props are requested. * Special:Recentchangeslinked will now include upload log entries * (bug 41281) Fixed ugly output if file size could not be extracted for multi-page media. * (bug 50315) list=logevents API module will now output log entries by anonymous users. * (bug 38911) Handle headers with rowspan in jquery.tablesorter * (bug 658) Converted the table of contents on wiki pages from to
and adjusted skin CSS accordingly. The CSS was carefully crafted to be backwards-compatible in all reasonable cases (uses of the __TOC__ magic word, the #toc CSS id and the .toc CSS class). However, particularly bad abuse of the id or the class can possibly break. * CSSJanus now supports rgb, hsl, rgba, and hsla color syntaxes. * Special:Listfiles can no longer be sorted by image name when filtering by user in miser mode. * (bug 49074) CSSJanus: Handle values of border-radius correctly. * Handle relative inclusions ({{../name}}) in main namespace with subpages enabled correctly (previously MediaWiki tried to include Template:Parent/name instead of just Parent/name). * Added $wgAPIUselessQueryPages to allow extensions to flag their query pages for non-inclusion in ApiQueryQueryPages. * (bug 50870) mediawiki.notification: Notification area should remain visible when scrolled down. * (bug 13438) Special:MIMESearch no longer an expensive special page. * (bug 48342) Fixed a fatal error when $wgValidateAllHtml is set to true and the function apache_request_headers() function is not available. * (bug 33399) LivePreview: Re-run wikipage content handlers (jquery.makeCollapsible, jquery.tablesorter) after preview content is loaded. * (bug 51891) Fixed PHP notice on Special:PagesWithProp when no properties are defined. * (bug 52006) Corrected documentation of $wgTranscludeCacheExpiry. * (bug 52077) The APIEditBeforeSave hook is giving the content of the whole revision as second argument now, rather than just the current section. * (bug 49694) $wgSpamRegex is now also applied on the new section headline text adding a new topic on a page * (bug 41756) Improve treatment of multiple comments on a blank line. * (bug 51064) Purge upstream caches when deleting file assets. * (bug 39012) File types with a mime that we do not know the extension for can no longer be uploaded as an extension that we do know the mime type for. * (bug 51742) Add data-sort-value for better sorting of hitcounts Special:Tags * (bug 26811) On DB error pages, server hostnames are now hidden when both $wgShowHostnames and $wgShowSQLErrors are false. * (bug 6200) line breaks in

Also, a "utf8" option is now provided to use UTF-8 encoding instead of hex escape codes for most non-ASCII characters. * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the parameter has had no effect since MediaWiki 1.16, and so its removal is unlikely to impact existing clients. * (bug 47216) action=query&meta=siteinfo&siprop=skins will now indicate which skin is the default and which are unusable (e.g. listed in $wgSkipSkins). * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled) to action=feedwatchlist. * WDDX formatted output will actually be formatted (and normal output will no longer be), and will no longer choke on booleans. * action=opensearch no longer silently ignores the format parameter. * action=opensearch now supports format=jsonfm. * list=usercontribs&ucprop=ids will now include the parent revision id. * (bug 47219) Allow specifying change type of Wikipedia feed items * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth * prop=info now adds the content model and page language of the title. * New upload log entries will now contain information on the relevant image (sha1 and timestamp). * (bug 49239) action=parse now can parse in preview and section preview modes. * (bug 49259) action=patrol now accepts revision ids. * (bug 48129) list=blocks&bkip= now correctly handles IPv6 CIDR ranges and honors $wgBlockCIDRLimit. Note any clients passing invalid values to bkip will now receive an error, rather than the previous behavior listing all user blocks. * (bug 48201) action=parse&text=foo now assumes wikitext if no title is given, rather than using the content model of the page "API". * action=watch no longer silently ignores hook abort. * (bug 50785) action=purge with forcelinkupdate=1 no longer queues refreshLinks jobs in the job queue for link table updates of pages that use the given page as a template. Instead, forcerecursivelinkupdate=1 is introduced and should be used if that behaviour is desirable. * The 'debugLog' property (enabled by $wgDebugToolbar) no longer sets the log entry values through ApiResult::content but directly. This changes the JSON output from an array of objects with content in '*' to an array of strings with the content. * (bug 51342) prop=imageinfo iicontinue now contains the dbkey, not the text version of the title. * (bug 52538) action=edit will now use empty text instead of the contents of section 0 when passed prependtext or appendtext with section=new. * Support for the 'gettoken' parameter to action=block and action=unblock, deprecated since 1.20, has been removed. * (bug 49090) Token-getting functions will fail when using jsonp callbacks. * (bug 52699) action=upload returns normalized file name on warning "exists-normalized" instead of filename to be uploaded to. * (bug 53884) action=edit will now return an error when the specified section does not exist in the page. * Added meta=filerepoinfo API module for getting information about foreign file repositories, and related ForeignAPIRepo methods getInfo and getApiUrl. * The new query module list=allfileusages to enumerate file usages was added. === Languages updated in 1.22.0 === MediaWiki supports over 350 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Bugzilla reports. * (bug 47099) Plural rules were updated to those from CLDR 24 for Manx (gv). * (bug 54514) Explicit plural forms now work for Russian. * (bug 46422) Explicit plural forms for languages that use a custom implementation for Language::convertPlural now work correctly. * Batak Toba (bbc-latn) added. * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian. === Other changes in 1.22.0 === * redirect.php was removed. It was unused. * ClickTracking integration was dropped from the mediaWiki.user.bucket JavaScript function. The 'tracked' option is now ignored. * Event namespace used by jquery.makeCollapsible has been changed from 'mw-collapse' to 'mw-collapsible' for consistency with the module name. * The Quickbar feature of the legacy skin model and the last remnants of it throughout the code base have been removed. * Externaledit/externaldiff preference was removed. Very few users used this feature, and improper configuration can actually prevent a user from editing * Calling Linker methods using a skin will now output deprecation warnings. * (bug 46680) "Return to" links are no longer tagged with rel="next". * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was added. * A new Special:Redirect page was added, providing lookup by revision ID, user ID, or file name. The old Special:Filepath page was reimplemented to redirect through Special:Redirect. * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9. * Support for XHTML 1.0 has been removed. MediaWiki now only outputs (X)HTML5. * wikibits: User-agent related globals have been deprecated. The following properties now default to false and emit mw.log.warn: is_gecko, is_chrome_mac, is_chrome, webkit_version, is_safari_win, is_safari, webkit_match, is_ff2, ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs, opera7_bugs, opera6_bugs, is_opera_95, is_opera_preseven, is_opera, and ie6_bugs. * (bug 48276) MediaWiki will now flash a confirmation message upon successfully editing a page. * (bug 40785) mediawiki.legacy.ajax has been marked as deprecated. The following properties now emit mw.log.warn when accessed: sajax_debug, sajax_init_object, sajax_do_call and wfSupportsAjax. * Methods Title::userCanEditCssSubpage and Title::userCanEditJsSubpage, deprecated since 1.19, have been removed. * (bug 50134) Hook functions are no longer required to return a value. When a hook function does not return a value (or when it returns an explicit null), processing continues. To abort the hook, a hook function must return an explicit, boolean false or a string error message. Other falsey values are tantamount to a 'return true' in earlier versions of MediaWiki. * (bug 48256) The 'editsection-brackets' optional message was removed. Section edit links' brackets can now be customized using CSS by styling span.mw-editsection-bracket. * The usePatrol function in ChangesList has been marked as deprecated. * (bug 50785) A "null edit", that is, a save action in which no changes to the page text are made and no revision recorded, will no longer send refreshLinks jobs to the job table to update pages which use the edited page as a template. * The LivePreviewPrepare and LivePreviewDone events triggered on "jQuery( mw )" have been deprecated in favour of using mw.hook. * The 'showjumplinks' user preference has been removed, jump links are now always included. * Methods RecentChange::notifyRC2UDP, RecentChange::sendToUDP, and RecentChange::cleanupForIRC have been deprecated, as it is now the responsibility of classes implementing the RCFeedFormatter and RCFeedEngine interfaces to implement the formatting and delivery for recent change notifications. * SpecialPrefixindex methods namespacePrefixForm() and showPrefixChunk() have been made protected. They were accepting form variance arguments, this is now using properties in the SpecialPrefixindex class. * (bug 49629) The hook ExtractThumbParamaters has been deprecated in favour of media handler overriding MediaHandler::parseParamString. * (bug 46512) The collapsibleNav feature from the Vector extension has been moved to the Vector skin in core. * SpecialRecentChanges::addRecentChangesJS() function has been renamed to addModules() and made protected. * Methods WatchAction::doWatch and WatchAction::doUnwatch now return a Status object instead of a boolean. * Information boxes (CSS classes errorbox, warningbox, successbox) have been made more subtle. * Code specific to the Math extension was marked as deprecated. * mediawiki.util: mw.util.wikiGetlink has been renamed to getUrl. (The old name still works, but is deprecated.) == Compatibility == MediaWiki 1.22.0 requires PHP 5.3.2 or later. MySQL 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. The supported versions are: * MySQL 5.0.2 or later * PostgreSQL 8.3 or later * SQLite 3.3.7 or later * Oracle 9.0.1 or later == Upgrading == 1.22.0 has several database changes since 1.21, 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). If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes. If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data. If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed with MediaWiki 1.21. Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed upgrade instructions. For notes on 1.21.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/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.
