Change notes from older releases. For current info see RELEASE-NOTES-1.24. == MediaWiki 1.23 == === Configuration changes in 1.23 === * (bug 13250) Restored method for clearing a watchlist in web UI so that users with large watchlists don't have to perform contortions to clear them. * When $wgJobRunRate is higher than zero, jobs are now executed via an asynchronous HTTP request to a MediaWiki entry point. This may require increasing the number of server worker threads. $wgRunJobsAsync has been added to disable this feature if needed, falling back to executing the job on the same process but making the execution synchronously. * $wgDebugLogGroups values may be set to an associative array with a 'destination' key specifying the log destination. The array may also contain a 'sample' key with a positive integer value N indicating that the log group should be sampled by dispatching one in every N messages on average. The sampling is random. * In addition to the current exception log format, MediaWiki now serializes exception metadata to JSON and logs it to the 'exception-json' log group. This makes MediaWiki easier to integrate with log aggregation and analysis tools. * $wgSquidServersNoPurge now supports the use of Classless Inter-Domain Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6 addresses that should be trusted to provide X-Forwarded-For headers. * Preferences 'watchcreations', 'watchdefault', 'enotifwatchlistpages' ("Add pages I create and files I upload to my watchlist", "Add pages and files I edit to my watchlist", "Email me when a page or file on my watchlist is changed") are now enabled by default. In addition new user accounts' personal and talk pages are now watched by them by default. * $wgLBFactoryConf: Class names have had underscores removed. The configuration should be updated if LBFactory_Simple or LBFactory_Multi is configured. * $wgPasswordSenderName has been removed and is no longer functional. To set a custom mailer name, the system message 'emailsender' should be modified (default: "{{SITENAME}}"). * (bug 63269) Email notifications were not correctly handling the [[MediaWiki:Helppage]] message being set to a full URL (the default). 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. * $wgDBAhandler was removed as the only class using it was also removed * The 'max threads' setting was removed from $wgDBservers. * Support for AdminSettings.php has been completely removed. All configuration belongs in LocalSettings.php. * $wgSkipSkin, which has been replaceable by $wgSkipSkins since 2005 (r9249), is now formally deprecated. * Removed deprecated $wgDisabledActions as it is hardly used anywhere. * $wgRateLimitLog has been deprecated and replaced by $wgDebugLogGroup['ratelimit']. * $wgLocalInterwikis is an array containing multiple local interwiki prefixes (interwiki prefixes that point back to the current wiki). This effectively allows more than one value of $wgLocalInterwiki to be specified and understood by the parser. The value of $wgLocalInterwiki is automatically prepended to the start of this array. * $wgQueryPages has been removed. Query Pages should be added to by using the wgQueryPages hook. * $wgHttpOnlyBlacklist has been removed. * $wgLicenseTerms has been removed as it was unused. * $wgProfileOnly is now deprecated; set the log file in $wgDebugLogGroups['profileoutput'] to replace it. * $wgMaxBacklinksInvalidate was removed; use $wgJobBackoffThrottling instead * Deprecated ResourceLoaderGetStartupModules hook. === New features in 1.23 === * ResourceLoader can utilize the Web Storage API to cache modules client-side. Compared to the browser cache, caching in Web Storage allows ResourceLoader to be more granular about evicting stale modules from the cache while retaining the ability to retrieve multiple modules in a single HTTP request. This capability can be enabled by setting $wgResourceLoaderStorageEnabled to true. This feature is currently considered experimental and should only be enabled with care. * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}} and {{REVISIONTIMESTAMP:}} (with friends). * Add "wgRelevantUserName" to mw.config containing the current Skin::getRelevantUser value. * (bug 56033) Add content model to the page information. * Added Article::MissingArticleConditions hook to give extensions a chance to hide their (unrelated) log entries. * Added LonelyPagesQuery hook to let extensions modify the query used to generate Special:LonelyPages. * Added $wgOpenSearchDefaultLimit defining the default number of entries to show on action=opensearch API call. * For namespaces with $wgNamespaceProtection (including the MediaWiki namespace), the "protect" tab will be shown only if there are restriction levels available that would restrict editing beyond what $wgNamespaceProtection already applies. The protection form will offer only those protection levels. * Added $wgAPIFormatModules, allowing extensions to add additional output formatting modules for the API. * (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add custom CSS or JavaScript enabled only for registered users. * (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist now include a legend describing the symbols used in lists of changes. * Improved the accessibility of the tabs in Special:Preferences. * Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook: it's called after everything is set up but before any major processing happens. * The jquery.client module now performs a component-wise version comparison in its #test method when strings are used in the browser map: version '1.10' is now correctly considered larger than '1.2'. Using numbers in the version map is not affected. * All API modules now support an assert parameter, which can either be 'user' or 'bot'. The API will throw an error if the user is not logged in (user) or does not have the 'bot' userright (bot). Based off of the AssertEdit extension by Steve Sanbeg. * [[Special:Diff]] was added, allowing users to create internal links to revision comparison pages using syntax such as [[Special:Diff/12345]], [[Special:Diff/12345/prev]] or [[Special:Diff/12345/98765]]. * New user accounts' personal and talk pages are now watched by them by default. * Added SkinTemplateGetLanguageLink hook to allow changing the html of language links. * Added MessageCache::get hook as a new way to customize messages across multiple sites. * Added jquery.throttle-debounce ResourceLoader module to limit the number of callbacks for frequently occurring events. * Special:ProtectedPages shows now a table. The timestamp, the reason and the protecting user is also shown. * Added experimental support for using Microsoft SQL Server as the database backend. ** Added new Microsoft SQL Server-specific configuration variable $wgDBWindowsAuthentication, which makes the web server authenticate against the database server using Integrated Windows Authentication instead of $wgDBuser/$wgDBpassword. * HTMLForm 'select', 'selectandother', 'selectorother', 'multiselect', and 'radio' fields can now use message keys as labels via the 'options-messages' parameter, which overrides the 'options' parameter. * Admins can expire users users passwords manually, or on a schedule using the $wgPasswordExpirationDays configuration setting. * Add new hook SendWatchlistEmailNotification, this will be used to determine whether to send a watchlist email notification. * (bug 42026) Special:Contributions now includes an option to filter page creations, similar to the topOnly option. * Add mediawiki.ui.button styling to all pages so wiki content can use styled buttons. * Special:UserLogin/signup now does AJAX checks for invalid and taken usernames, displaying the error live. * Added BaseTemplateAfterPortlet hook to allow injecting html after portlets in skins. * Support has been added for a JSON based localisation file format. The installer has been updated to use it. * Changes to content typography (colors, line-height etc.). See https://www.mediawiki.org/wiki/Typography_refresh for further information. * The Vector skin's visual treatment of external links has been simplified to a single icon (from nine). This should not affect local rules unless they were re-using these icons, which have now been deleted. * ResourceLoader: mw.loader.using() now implements a Promise interface. * Add new hook ChangesListInitRows accessed via ChangesList::initChangesListRows. If called by the ChangesList consumer this gives extensions a chance to batch process the result set prior to rendering. * A PoolCounterRedis class was added which can be make use of in $wgPoolCounterConf. This requires at least one Redis 2.6+ server. * $wgProfileToDatabase was removed. Set $wgProfiler to ProfilerSimpleDB in StartProfiler.php instead of using this. * (bug 63444) Made it possible to change the indent string (default: 4 spaces) used by FormatJson::encode(). === Bug fixes in 1.23 === * (bug 41759) The "updated since last visit" markers (on history pages, recent changes and watchlist) and the talk page message indicator are now correctly updated when the user is viewing old revisions of pages, instead of always acting as if the latest revision was being viewed. * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code" when the email address is already confirmed. Also, consistently use "confirmed", rather than "authenticated", when messaging whether or not the user has confirmed an email address. * (bug 19415) action=render no longer shows section edit links. This affects behavior of several other features where (bogus) section edit links will disappear, such as file description pages loaded via $wgUseInstantCommons or pages transcluded cross-wiki via $wgEnableScaryTranscluding. * (bug 56912) Show correct link color on cached result of Special:DeadendPages. * Classes TitleListDependency and TitleDependency have been removed, as they have been found unused in core and extensions for a long time. * (bug 57098) SpecialPasswordReset now obeys returnto parameter * (bug 37812) ResourceLoader will notice when a module's definition changes and recompile it accordingly. * (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds. * (bug 58640) Fixed a compatibility issue with PCRE 8.34 that caused pages to appear blank or with missing text. * (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. * (bug 23542) imagelinks now stores both the redirect and target (as templatelinks does). * (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 56199) Raw option of parser functions must now match complete word, to take effect. * (bug 60543) Special:PrefixIndex forgot stripprefix=1 for "Next page" link * (bug 29762) Undoing an already-undone edit will now display an appropriate message instead of leading the user to make a null edit. * (bug 52659) mediawiki.notification: Notification area remained visible when empty and thus was stealing pointer events from links on the page. * (bug 26811) When a DBUnexpectedError occurs, DB server hostnames are now hidden unless $wgShowExceptionDetails is true, and $wgShowDBErrorBacktrace no longer applies in such cases. * (bug 60960) Avoid doing file_exist() checks on data: URIs, as they cause warnings to be printed on Windows due to large path length. * (bug 48084) Fixed a bug in the installer that could cause $wgLogo to hold the wrong path to the placeholder logo (skins/common/images/wiki.png). * (bug 64289) jquery.textSelection: Don't throw errors on empty collections. === Web API changes in 1.23 === * (bug 54884) action=parse&prop=categories now indicates hidden and missing categories. * action=query&meta=filerepoinfo now returns additional information for each repo. * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in MediaWiki 1.24. * action=parse now has disabletoc flag to disable table of contents in output. * (bug 25702) list=allcategories, list=allimages, list=alllinks, list=allpages, list=deletedrevs and list=filearchive did not handle case-sensitivity properly for all parameters. * ApiQueryBase::titlePartToKey allows an extra parameter that indicates the namespace in order to properly capitalize the title part. * (bug 57874) action=feedcontributions no longer has one item more than limit. * All API modules now support an assert parameter. See the new features section for more details. * Added prop=contributors to fetch the list of contributors to the page. * The following API modules will now return entries where fields have been revision-deleted: list=deletedrevs, list=filearchive, list=recentchanges, list=watchlist. "hidden" indicators will be included, in the same style as is already done for prop=revisions. * The following API modules will now return the content of revision-deleted fields, in addition to the "hidden" indicators, if the querying user has the necessary rights: list=logevents, list=usercontribs, prop=imageinfo, prop=revisions. * The above modules, where applicable, will now return entries filtered by revision-deleted fields if the querying user has the necessary rights. For example, prop=revisions with rvuser or rvexcludeuser will no longer skip revisions where the user was revision-deleted if the current user has the deletedhistory right. * The 'hideuser' right, used when blocking, is no longer necessary or sufficient for seeing contributions with revision-deleted in list=usercontribs. * list=watchlist now uses the querying user's rights rather than the wlowner's rights when checking whether wlprop=patrol is allowed. * (bug 32151) ApiWatch now has pageset capabilities (titles/pageids/generators). Title parameter is now deprecated. * (bug 23005) Added action=revisiondelete. * Added siprop=restrictions to API action=query&meta=siteinfo for querying possible page restriction (protection) levels and types. * Added prop 'limitreportdata' and 'limitreporthtml' to action=parse. * (bug 58627) Provide language names on action=parse&prop=langlinks. * Deprecated llurl= in favour of llprop=url for action=query&prop=langlinks. * Added llprop=langname and llprop=autonym for action=query&prop=langlinks. * prop=redirects is added, to return redirects to the pages in the query. * list=allredirects is added, to list all redirects pointing to a namespace. * (bug 42026) Added ucshow={new,!new,top,!top} to list=usercontribs. Also added newonly to action=feedcontributions. * (bug 42026) Deprecated uctoponly in favor of ucshow=top. * list=search no longer has a "srredirects" parameter. Redirects are now included in all searches. * Added list=prefixsearch that works like action=opensearch but can be used as a generator. * (bug 24782) Various modules will now use unique continuation parameters. * (bug 63249) Cache RecentChanges Atom feed in varnish for 15 seconds. === Languages updated in 1.23 === 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. * Support was added for Algerian Spoken Arabic (arq). * Support was added for Riograndenser Hunsrückisch (hrx). * Support was added for Northern Luri (lrc). === Other changes in 1.23 === * The rc_type field in the recentchanges table has been superseded by a new rc_source field. The rc_source field is a string representation of the change type where rc_type was a numeric constant. This field is not yet queried but will be in a future release. ** Utilize update.php to create and populate this new field. On larger wikis which do not wish to update recentchanges table in one large update please review the SQL and comments in maintenance/archives/patch-rc_source.sql. ** The rc_type field of recentchanges will be deprecated in a future release. * The global variable $wgArticle has been removed after a lengthy deprecation. * The global functions addButton and insertTags (for mw.toolbar.addButton and mw.toolbar.insertTags) now emits mw.log.warn when accessed. * The ExpandTemplates extension has been moved into MediaWiki core. * (bug 52812) Removed "Disable search suggestions" from Preference. * (bug 52809) Removed "Disable browser page caching" from Preference. * Three new modules intended for use by custom skins were added: 'mediawiki.skinning.elements', 'mediawiki.skinning.content', and 'mediawiki.skinning.interface', representing three levels of standard MediaWiki styling. Previously skin creators wishing to use them had to refer to the file names of appropriate files directly, which is now discouraged. * The modules 'skins.vector' and 'skins.monobook' have been renamed to 'skins.vector.styles' and 'skins.monobook.styles', respectively, and their definition was changed not to include the common*.css files; the two skins now load the 'mediawiki.skinning.interface' module instead. * A page_links_updated field has been added to the page table. * SpecialPage::getTitle has been deprecated in favor of SpecialPage::getPageTitle. * BREAKING CHANGE: Two potentially backwards-incompatible changes have been made to the 'SpecialWatchlistQuery' hook's last parameter (array $values) to make the hook more consistent with the 'SpecialRecentChangesQuery' one: ** Several array keys have been renamed: hideMinor → hideminor, hideBots → hidebots, hideAnons → hideanons, hideLiu → hideliu, hidePatrolled → hidepatrolled, hideOwn → hidemyself. ** The parameter value is now a FormOptions object, not a plain array (array access operators should continue to work, as it implements the ArrayAccess interface). * Option to mark hooks as deprecated has been added. * (bug 52811) Preference "Enable section editing via [edit] links" was removed. * (bug 52813) Preference "Show table of contents (for pages with more than 3 headings)" was removed. * (bug 52810) Preference "Justify paragraphs" was removed. * OutputPage::showErrorPage raises a notice if arguments are incoherent. * Thumbnails that keep failing to render in thumb.php will be rate-limited againt further render attempts for 1 hour. $wgAttemptFailureEpoch can be altered to reset all rate-limited thumbnails at once. * (bug 56572) Builds of the OOjs and OOjs UI libraries are now available. * mw.loader.go and mw.loader.version have been removed. * (bug 52815) Preference "Enable simplified search bar (Vector skin only)" was removed. * A user_password_expires column has been added to the user table. The User object expects this column to exist. Use update.php to create this new field. * The jquery.delayedBind ResourceLoader module was deprecated in favor of the jquery.throttle-debounce module. It will be removed in MediaWiki 1.24. * mw.user.bucket has been deprecated. * On Special:PrefixIndex, a table#mw-prefixindex-list-table was changed to table.mw-prefixindex-list-table to avoid duplicate ids when the special page is transcluded. * (bug 62198) window.$j has been deprecated. * Preference "Disable link title conversion" was removed. * SpecialRecentChanges no longer includes any functionality for generating feeds - it has been factored out to ApiFeedRecentChanges. Old URLs redirect to new ones. * RecentChange::mExtra['lang'] is no longer set and should no longer be used. Extensions should read from other configuration variables, including $wgLocalInterwikis, to identify the current wiki. * Sections in the parser test framework have been renamed and the old section names are deprecated. Please use "!!wikitext" and "!!html" (or "!!html/php") instead of "!!input" and "!!result". This allows us to extend parser tests to accommodate additional input/output pairs, such as "!!html/parsoid" (for the output of the Parsoid parser, where it differs from the PHP parser). * Special:Search no longer has an "include redirects" option on the advanced tab. Redirects are now included in all searches. * mediawiki.api.category's getCategories() 'async' parameter was deprecated. * The locations of resources have been split between upstream libraries, now in resources/lib/, local libaries in resources/src/, and local forks of upstream libraries, also in resources/src/. * BREAKING CHANGE: The automatically-generated function closure with which ResourceLoader wraps all modules' JavaScript code now binds the identifier names 'jQuery' and '$' to the jQuery object of the version of jQuery that is bundled with MediaWiki. If you bind these names to other objects in global scope (like Zepto.js or document.querySelectorAll, for example) you will need to use different names to or re-bind them at the top of each ResourceLoader-loaded module. * (bug 52342) Preference "Remember my login" was removed. * The skin autodiscovery mechanism has been deprecated and will be removed in MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for migration guide for creators and users of custom skins that relied on it. ==== Removed classes ==== * FakeMemCachedClient (deprecated in 1.18) * RdfMetaData (unused) * TitleDependency (unused) * TitleListDependency (unused) * WikiError (deprecated in 1.17) * WikiXmlError (deprecated in 1.17) * WikiErrorMsg (deprecated in 1.17) ==== Renamed classes ==== * CdbReader_DBA to CdbReaderDBA * CdbReader_PHP to CdbReaderPHP * CdbWriter_DBA to CdbWriterDBA * CdbWriter_PHP to CdbWriterPHP * DiffOp_Add to DiffOpAdd * DiffOp_Change to DiffOpChange * DiffOp_Copy to DiffOpCopy * DiffOp_Delete to DiffOpDelete * HWLDF_WordAccumulator to HWLDFWordAccumulator * LBFactory_Fake to LBFactoryFake * LBFactory_Multi to LBFactoryMulti * LBFactory_Simple to LBFactorySimple * LBFactory_Single to LBFactorySingle * LCStore_Accel to LCStoreAccel * LCStore_CDB to LCStoreCDB * LCStore_DB to LCStoreDB * LCStore_Null to LCStoreNull * LoadBalancer_Single to LoadBalancerSingle * LoadMonitor_MySQL to LoadMonitorMySQL * LoadMonitor_Null to LoadMonitorNull * LocalisationCache_BulkLoad to LocalisationCacheBulkLoad * csvStatsOutput to CsvStatsOutput * extensionLanguages to ExtensionLanguages * languages to Languages * statsOutput to StatsOutput * textStatsOutput to TextStatsOutput * wikiStatsOutput to WikiStatsOutput ==== Removed methods ==== * ApiBase::getValidNamespaces() (deprecated in 1.17) * ApiMain::setCachePrivate() (deprecated in 1.17) * ApiMain::setVaryCookie (deprecated in 1.17) * Article::doRedirect() (deprecated in 1.18) * Article::doUnwatch() (deprecated in 1.18) * Article::doWatch() (deprecated in 1.18) * Article::forUpdate() (deprecated in 1.18) * Article::markpatrolled() (deprecated in 1.18) * Article::unwatch() (deprecated in 1.18) * Article::watch() (deprecated in 1.18) * Block::clear() (deprecated in 1.18) * Block::decodeExpiry() (deprecated in 1.18) * Block::encodeExpiry() (deprecated in 1.18) * Block::forUpdate() (deprecated in 1.18) * Block::infinity() (deprecated in 1.18) * Block::load() (deprecated in 1.18) * Block::newFromDB() (deprecated in 1.18) * Block::normaliseRange() (deprecated in 1.18) * Block::parseExpiryInput() (deprecated in 1.18) * CategoryViewer::addSubcategory() (deprecated in 1.17) * EditPage::spamPage() (deprecated since 1.17) * Exif::getFormattedData() (deprecated in 1.18) * Exif::makeFormattedData() (deprecated in 1.18) * in_string (deprecated in 1.21) * Language::convertLinkToAllVariants() (deprecated in 1.17) * LanguageConverter::convertLinkToAllVariants() (deprecated in 1.17) * Linker::makeBrokenLink() (deprecated in 1.16) * Linker::makeBrokenLinkObj() (deprecated in 1.16) * Linker::makeColouredLinkObj() (deprecated in 1.16) * Linker::makeSizeLinkObj() (deprecated in 1.17) * MediaWiki::articleFromTitle() (deprecated in 1.18) * ParserOptions::getkin() (deprecated 1.18) * ProfilerSimple::getCpuTime (deprecated in 1.20) * Revision::revText() (deprecated in 1.17) * SkinTemplate::jstext() (deprecated in 1.21) * SpecialPage::__call() (deprecated in 1.17) * SpecialPage::executePath() (deprecated in 1.18) * SpecialPage::exists() (deprecated in 1.18) * SpecialPage::file() (deprecated in 1.18) * SpecialPage::func() (deprecated in 1.18) * SpecialPage::getGroup() (deprecated in 1.18) * SpecialPage::getPage() (deprecated in 1.18) * SpecialPage::getPageByAlias() (deprecated in 1.18) * SpecialPage::getLocalNameFor() (deprecated in 1.18) * SpecialPage::getRegularPages() (deprecated in 1.18) * SpecialPage::getRestrictedPages() (deprecated in 1.18) * SpecialPage::getTitleForAlias() (deprecated in 1.18) * SpecialPage::getUsablePages() (deprecated in 1.18) * SpecialPage::includable() (deprecated in 1.18) * SpecialPage::init() * SpecialPage::initAliasList() (deprecated in 1.18) * SpecialPage::initList() (deprecated in 1.18) * SpecialPage::name() (deprecated in 1.18) * SpecialPage::removePage() (deprecated in 1.18) * SpecialPage::resolveAlias() (deprecated in 1.18) * SpecialPage::resolveAliasWithSubpage() (deprecated in 1.18) * SpecialPage::restriction() (deprecated in 1.18) * SpecialPage::setGroup() (deprecated in 1.18) * SpecialRecentChanges::feedSetup() * SpecialRevisionDelete::extractBitField() (deprecated in 1.22) * User::getPageRenderingHash() (deprecated in 1.17) * WebRequest::getFileSize() (deprecated in 1.17) * WebRequest::isPathInfoBad() (deprecated in 1.17) * wfGenerateToken (deprecated in 1.20) * wfStreamFile (deprecated in 1.19) * wfUILang (deprecated in 1.18) * WikiPage::createUpdates() (deprecated in 1.18) * WikiPage::quickEdit() (deprecated in 1.18) * WikiPage::useParserCache() (deprecated in 1.18) * WikiPage::viewUpdates() (deprecated in 1.18) ==== Removed globals ==== * $wgBetterDirectionality (deprecated in 1.18) == MediaWiki 1.22 == === Configuration changes in 1.22 === * $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). === New features in 1.22 === * You can now install extensions using Composer. See https://www.mediawiki.org/wiki/Composer * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes. * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports the "eIOPTZ" formatting characters. * EditWarning: A warning is shown when an editor leaves the edit form without saving (enabled by default, users can opt-out via the 'useeditwarning' preference). This feature was moved from the Vector extension, and is now part of core for all skins. Take care when upgrading that you don't use an older version of the Vector extension as this feature may conflict. * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a compact vertical form layout. * HTMLForm supports a new display format 'vform' which applies this compact vertical layout and button styling. Special:PasswordReset uses this format. * New versions of login (Special:UserLogin) and create account (Special:UserLogin/signup) forms using the "vform" compact vertical form layout. These forms use new messages that assume a "Help logging in" link, see https://www.mediawiki.org/wiki/Manual:Page_customizations; https://www.mediawiki.org/wiki/Account_creation_user_experience/Strings lists the message key changes. * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default). * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was added. * (bug 25592) LogEventsList::showLogExtract() will now ignore various Pager-related WebRequest parameters by default, as this is overwhelmingly likely to be what was intended by users of the method. If any caller wishes to use these parameters, the new param 'useRequestParams' may be set to true. * mw.util.addPortletLink: Tooltip is no longer required to be plain (without an accesskey in it already). As such it now rountrips. Creating a link with a message as tooltip, grabbing the title attribute and using it to create another portlet will work as expected. * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost page without namespace. * 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 45535) introduced the new 'LanguageLinks' hook for manipulating the language links associated with a page before display. * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen' * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen' * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches of the specified languages instead of all of them. * New GetNewMessagesAlert hook allowing extensions to disable or modify the new messages alert * New wgUserNewMsgRevisionId JS global for logged in users. This will be null if the user has no new talk page messages. Otherwise it will be set to the revision ID of the oldest new talk page message. This will allow gadgets and extensions to create their own new message alerts on the client side. * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace). * mediawiki.log: Implemented log.deprecate. This method defines a property and uses ES5 getter/setter to emit a warning when they are used. * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels which can be cascading (previously 'sysop' was hard-coded as the only one). * XHTML5 support has been improved. If you set $wgMimeType = 'application/xhtml+xml' MediaWiki will try outputting markup acording to XHTML5 rules. * Altered hook 'ProtectionForm::save', adding the reason page protection is changed as third parameter. * New hook 'TitleSquidURLs' for manipulating the list of URLs to be purged from HTTP caches when a page is changed. * Changed the patrolling system to always show the link for patrolling in case the current revision is patrollable. This also removed the usage of the rcid URI parameters. * Oracle DB backend now supports Database Resident Connection Pooling (DRCP). Can be enabled by setting $wgDBOracleDRCP=true. Requires Oracle DB 11gR1 or above, enabled DRCP inside the DB itself and a propper connect string. More about DRCP can be found at: http://www.oracle-base.com/articles/11g/database-resident-connection-pool-11gr1.php * Add a new parameter $patrolFooterShown to hook ArticleViewFooter so the hook handlers can take further action based on the status of the patrol footer * A new hook TitleQuickPermissions was added to allow overriding of quick permissions in the Title class. * LinkCache singleton can now be altered or cleared, letting one to specify another instance that does not rely on a database backend. * MediaWiki's PHPUnit tests can now use PHPUnit installed using composer --dev. * (bug 43689) The lists of templates used on the page and hidden categories it is a member of, shown below the edit form, are now collapsible (and collapsed by default). * Parser profiling data, formerly only available in the "NewPP limit report" HTML comment, is now also displayed at the bottom of page previews. * Added ParserLimitReportPrepare and ParserLimitReportFormat hooks, deprecated ParserLimitReport hook. * New user rights have been added to increase granularity in rights management for extensions such as OAuth: ** editmyusercss controls whether a user may edit their own CSS subpages. ** editmyuserjs controls whether a user may edit their own JS subpages. ** viewmywatchlist controls whether a user may view their watchlist. ** editmywatchlist controls whether a user may edit their watchlist. ** viewmyprivateinfo controls whether a user may access their private information (e.g. registered email address, real name). ** editmyprivateinfo controls whether a user may change their private information. ** editmyoptions controls whether a user may change their preferences. * Add new hook AbortTalkPageEmailNotification, this will be used to determine whether to send the regular talk page email notification * Action classes registered in $wgActions are now also supported in the form of a callback (which returns an instance of Action) instead of providing the name of a subclass of Action. * (bug 46513) Vector: Add the collapsibleTabs script from the Vector extension. * Added $wgRecentChangesFlags for defining new flags for RecentChanges and watchlists. * (bug 40518) mw.toolbar: Implemented mw.toolbar.addButtons for adding multiple button objects in one call. * Rights used for the default protection levels ('sysop' and 'autoconfirmed') are now used just for that purpose, instead of overloading other rights. This allows easy granting of the ability to edit sysop-protected pages without also granting the ability to protect and unprotect. * (bug 48256) Make brackets in section edit links accessible to CSS. They are now wrapped in . * (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. === Bug fixes in 1.22 === * (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
are handled like they are in
* (bug 14931) Default character set now set to 'utf8' when a new MySQL database is created. * (bug 47191) Fixed "Column 'si_title' cannot be part of FULLTEXT index" MySQL error when installing using the binary character set option. * (bug 45288) Support mysqli PHP extension * (bug 55818) BREAKING CHANGE: Removed undocumented 'Debug' hook in wfDebug. This resolves an infinite loop when using $wgDebugFunctionEntry = true. * (bug 56707) Correct tooltip of "Next n results" on query special pages. * (bug 56770) mw.util.addPortletLink: Check length before access array index. === API changes in 1.22 === * (bug 25553) The JSON output formatter now leaves forward slashes unescaped to improve human readability of URLs and similar strings. 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. * 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. * (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=== 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. * Batak Toba (bbc-latn) added. * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian. === Other changes in 1.22 === * 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). * redirect.php was removed. It was unused. * ClickTracking integration was dropped from the mediaWiki.user.bucket JavaScript function. The 'tracked' option is now ignored. * 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. * Event namespace used by jquery.makeCollapsible has been changed from 'mw-collapse' to 'mw-collapsible' for consistency with the module name. * 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. * 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". * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the accesskey character is now $6 instead of $5. * 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. * BREAKING CHANGE: meta keywords are no longer supported. A ,
