+Change notes from older releases. For current info see RELEASE-NOTES-1.23.
+
+== 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 <span class="mw-editsection-bracket" />.
+* (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.
+* <wbr> 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 <gallery> 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 <http://leafo.net/lessphp/docs/#custom_functions>
+ 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 <hN> headings containing line breaks are now handled
+ correctly.
+* (bug 45803) Whitespace within == Headline == syntax and within <hN> 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 <kbd>, <samp>, and <var> 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 <table> to <div>
+ 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 <blockquote> are handled like they are in <div>
+* (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 <meta name="keywords"
+ will no longer be output and OutputPage::addKeyword no longer exists.
+* 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.
+* BREAKING CHANGE: The EditSectionLink hook was removed after being
+ deprecated since MediaWiki 1.14. Use DoEditSectionLink instead.
+* (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 50310) BREAKING CHANGE: wikibits: Drop support for mwCustomEditButtons.
+ It defaults to an empty array and emits mw.log.warn when accessed.
+* BREAKING CHANGE: Special:Disambiguations has been removed from MediaWiki core.
+ Functions related to disambiguation pages are now handled by the Disambiguator
+ extension (https://www.mediawiki.org/wiki/Extension:Disambiguator) (bug
+ 35981).
+* BREAKING CHANGE: The 'mediawiki.legacy.wikiprintable' module has been removed.
+ The skins/common/wikiprintable.css file no longer exists. Return value of
+ Skin#commonPrintStylesheet is ignored. Please use the 'mediawiki.legacy.commonPrint'
+ module instead or base your skin on SkinTemplate.
+* (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.
+* BREAKING CHANGE: The module 'mediawiki.legacy.IEFixes' has been removed as it was
+ unused. The file skins/common/IEFixes.js remains but is only used by wikibits.
+ The file never contained any re-usable components. To use it in a skin, load
+ 'mediawiki.legacy.wikibits' (which IEFixes depends on) and that will import
+ IEFixes automatically if user agent conditions are met.
+* 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.)
+
+== MediaWiki 1.21 ==
+
+=== Configuration changes in 1.21 ===
+* (bug 29374) $wgVectorUseSimpleSearch is now enabled by default.
+* Deprecated $wgAllowRealName is removed. Use $wgHiddenPrefs[] = 'realname'
+ instead.
+* (bug 39957) Added $wgUnwatchedPageThreshold, specifying minimum count
+ of page watchers required for the number to be accessible to users
+ without the unwatchedpages permission.
+* $wgBug34832TransitionalRollback has been removed.
+* (bug 29472) $wgUseDynamicDates has been removed and its functionality
+ disabled.
+
+=== New features in 1.21 ===
+* (bug 38110) Schema changes (adding or dropping tables, indices and
+ fields) can be now be done separately from from other changes that
+ update.php makes. This is useful in environments that use database
+ permissions to restrict schema changes but allow the DB user that
+ MediaWiki normally runs as to perform other changes that update.php
+ makes. Schema changes can be run separately. See the file UPGRADE
+ for more information.
+* (bug 34876) jquery.makeCollapsible has been improved in performance.
+* Added ContentHandler facility to allow extensions to support other content
+ than wikitext. See docs/contenthandler.txt for details.
+* New feature was developed for showing high-DPI thumbnails for high-DPI mobile
+ and desktop displays (configurable with $wgResponsiveImages).
+* Added new backend to represent and store information about sites and site
+ specific configuration.
+* jQuery upgraded from 1.8.2 to 1.8.3.
+* jQuery UI upgraded from 1.8.23 to 1.8.24.
+* Added separate fa_sha1 field to filearchive table. This allows sha1
+ searches with the api in miser mode for deleted files.
+* Add initial and programmatic sorting for tablesorter.
+* Add the event "sortEnd.tablesorter", triggered after sorting has completed.
+* The Job system was refactored to allow for different backing stores for
+ queues as well as cross-wiki access to queues, among other things. The schema
+ for the DB queue was changed to support better concurrency and reduce
+ deadlock errors.
+* Added ApiQueryORM class to facilitate creation of query API modules based on
+ tables that have a corresponding ORMTable class.
+* (bug 40876) Icon for PSD (Adobe Photoshop) file types.
+* (bug 40641) Implemented Special:Version/Credits with a list of contributors.
+* (bug 7851) Implemented one-click AJAX patrolling.
+* The <data>, <time>, <meta>, and <link> elements are allowed within WikiText
+ for use with Microdata.
+* The HTML5 <mark> tag has been whitelisted.
+* Added ParserCloned hook for when the Parser object is cloned.
+* Added AlternateEditPreview hook to allow extensions to replace the page
+ preview from the edit page.
+* Added EditPage::showStandardInputs:options hook to allow extensions to add
+ new fields to the "editOptions" area of the edit form.
+* Upload stash DB schema altered to improve upload performance.
+* The following global functions are now reporting deprecated warnings in
+ debug mode: wfMsg, wfMsgNoTrans, wfMsgForContent, wfMsgForContentNoTrans,
+ wfMsgReal, wfMsgGetKey, wfMsgHtml, wfMsgWikiHtml, wfMsgExt, wfEmptyMsg. Use
+ the Message class, or the global method wfMessage.
+* Added $wgEnableCanonicalServerLink, off by default. If enabled, a
+ <link rel=canonical> tag is added to every page indicating the correct server
+ to use.
+* Debug message emitted by wfDebugLog() will now be prefixed with the group
+ name when its logged to the default log file. That is the case whenever the
+ group has no key in wgDebugLogGroups, that will help triage the default log.
+* (bug 24620) Add types to LogFormatter.
+* jQuery JSON upgraded from 2.3 to 2.4.0.
+* Added GetDoubleUnderscoreIDs hook, for modifying the list of magic words.
+* DatabaseUpdater class has two new methods to ease extensions schema changes:
+ dropExtensionIndex and renameExtensionIndex.
+* New preference type - 'api'. Preferences of this type are not shown on
+ Special:Preferences, but are still available via the action=options API.
+* (bug 39397) Hide rollback link if a user is the only contributor of the page.
+* $wgPageInfoTransclusionLimit limits the list size of transcluded articles
+ on the info action. Default is 50.
+* Added action=createaccount to allow user account creation.
+* (bug 40124) action=options API also allows for setting of arbitrary
+ preferences, provided that their names are prefixed with 'userjs-'. This
+ officially reenables the feature that was undocumented and defective
+ in MW 1.20 (saving preferences using Special:Preferences cleared any
+ additional fields) and which has been disabled in 1.20.1 as a part of
+ a security fix (bug 42202).
+* Added option to specify "others" as author in extension credits using
+ "..." as author name.
+* Added the ability to limit the wall clock time used by shell processes,
+ as well as the CPU time. Configurable with $wgMaxShellWallClockTime.
+* Allow memory of shell subprocesses to be limited using Linux cgroups
+ instead of ulimit -v, which tends to cause deadlocks in recent versions
+ of ImageMagick. Configurable with $wgShellCgroup.
+* Added $wgWhitelistReadRegexp for regex whitelisting.
+* (bug 5346) Categories that are redirects will be displayed italic in
+ the category links section at the bottom of a page.
+* (bug 43915) New maintenance script deleteEqualMessages.php.
+* You can now create checkbox option matrices through the HTMLCheckMatrix
+ subclass in HTMLForm.
+* WikiText now permits the use of WAI-ARIA's role="presentation" inside of
+ html elements and tables. This allows presentational markup, especially
+ tables. To be marked up as such.
+* maintenance/sql.php learned the --cluster option. Let you run the script
+ on some external cluster instead of the primary cluster for a given wiki.
+* (bug 20281) test the parsing of inline URLs.
+* Added Special:PagesWithProp, which lists pages using a particular page property.
+* Implemented language-specific collations for category sorting for 67 languages
+ based in latin, greek and cyrillic alphabets. This allows one to *finally* get
+ articles to be correctly sorted on category pages. They are named
+ 'uca-<langcode>', where <langcode> is one of: af, ast, az, be, bg, br, bs, ca,
+ co, cs, cy, da, de, dsb, el, en, eo, es, et, eu, fi, fo, fr, fur, fy, ga, gd,
+ gl, hr, hsb, hu, is, it, kk, kl, ku, ky, la, lb, lt, lv, mk, mo, mt, nl, no,
+ oc, pl, pt, rm, ro, ru, rup, sco, sk, sl, smn, sq, sr, sv, tk, tl, tr, tt, uk,
+ uz, vi.
+* Added 'CategoryAfterPageAdded' and 'CategoryAfterPageRemoved' hooks.
+* Added 'HistoryRevisionTools' and 'DiffRevisionTools' hooks.
+* Added 'SpecialSearchResultsPrepend' and 'SpecialSearchResultsAppend' hooks.
+* (bug 33186) Add image rotation api "imagerotate"
+* (bug 34040) Add "User rights management" link on user page toolbox.
+* (bug 45526) Add QUnit assertion helper "QUnit.assert.htmlEqual" for asserting
+ structual equality of HTML (ignoring insignificant differences like
+ quotmarks, order and whitespace in the attribute list).
+* (bug 23393) HTML <hN> headings containing line breaks are now handled
+ correctly.
+* (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
+ is now non-significant and not preserved in the HTML output.
+
+=== Bug fixes in 1.21 ===

+* (bug 40352) fixDoubleRedirects.php should support interwiki redirects.
+* (bug 9237) SpecialBrokenRedirect should not list interwiki redirects.

+ recentchanges table.
+* (bug 32951) Do not register internal externals with absolute protocol,
+ when server has relative protocol.
+* (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
+ method requests, we now send a Host header by default, for Varnish
+ compatibility. This also works with Squid in reverse-proxy mode. If you wish
+ to support Squid configured in forward-proxy mode, set
+ $wgSquidPurgeUseHostHeader to false.
+* (bug 37020) sql.php with readline eats semicolon.
+* (bug 11748) Properly handle optionally-closed HTML tags when Tidy is
+ disabled, and don't wrap HTML-syntax definition lists in paragraphs.

+ current revision.
+* (bug 41494) Honor $wgLogExceptionBacktrace when logging non-API exceptions
+ caught during API execution.
+* (bug 37963) Fixed loading process for user options.
+* (bug 26995) Update filename field on Upload page after having sanitized it.
+* (bug 41793) Contribution links to users with 0 edits on Special:ListUsers
+ didn't show up red.
+* (bug 41899) A PHP notice no longer occurs when using the "rvcontinue" API
+ parameter.
+* (bug 42036) Account creation emails now contain canonical (not
+ protocol-relative) URLs.
+* (bug 41990) Fix regression: API edit with redirect=true and lacking
+ starttimestamp and basetimestamp should not cause an edit conflict.

+ needed.
+* (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
+ actually sorted.
+* (bug 2865) User interface HTML elements don't use lang attribute.
+ (completed the fix by adding the lang attribute to firstHeading).
+* (bug 42173) Removed namespace prefixes on Special:UncategorizedCategories.
+* (bug 36053) Log in "returnto" feature forgets query parameters if no
+ title parameter was specified.
+* (bug 42410) API action=edit now returns correct timestamp for the new edit.
+* (bug 14901) Email notification mistakes log action for new page creation.
+ Enotif no longer sends "page has been created" notifications for some log
+ actions. The following events now have a correct message: page creation,
+ deletion, move, restore (undeletion), change (edit). Parameter
+ $CHANGEDORCREATED is deprecated in 'enotif_body' and scheduled for removal in
+ MediaWiki 1.23.
+* (bug 457) In the sidebar of Vector, CologneBlue, Monobook, and Monobook-based
+ skins, the heading levels have been changed from (variously per skin)
+ <h4>, <h5> or <h6> to only <h3>s, with a <h2> hidden heading above them.
+ If you are styling or scripting the headings in a custom way, this change
+ will require updates to your site's CSS or JS.
+* (bug 41342) jquery.suggestions should cancel any active (async) fetches
+ before it triggers another fetch.
+* (bug 42184) $wgUploadSizeWarning missing second variable.
+* (bug 34581) removeUnusedAccounts.php maintenance script now ignores newuser

+* (bug 41733) Hide "New user message" (.usermessage) element from printable view.
+* (bug 39062) Special:Contributions will display changes that don't have

+* wfMerge() now works if $wgDiff3 contains spaces
+* (bug 43052) mediawiki.action.view.dblClickEdit.dblClickEdit should trigger
+ ca-edit click instead opening URL directly.
+* (bug 43964) Invalid value of "link" parameter in <gallery> no longer produces
+ a fatal error.

+* (bug 45069) wfParseUrl() no longer produces a PHP notice if passed a "mailto:"
+ URL without address
+* (bug 45012) Creating an account by e-mail can no longer show a
+ "password mismatch" error.
+* (bug 44599) On Special:Version, HEADs for submodule checkouts (e.g. for
+ extensions) performed using Git 1.7.8+ should now appear.
+* (bug 42184) $wgUploadSizeWarning missing second variable

+ script in includes/DefaultSettings.php
+* (bug 45143) jquery.badge: Treat non-Latin variants of zero as zero as well.
+* (bug 46151) mwdocgen.php should not ignore exit code of doxygen command.
+* (bug 41889) Fix $.tablesorter rowspan exploding for complex cases.
+
+=== API changes in 1.21 ===
+* prop=revisions can now report the contentmodel and contentformat.
+ See docs/contenthandler.txt.
+* action=edit and action=parse now support contentmodel and contentformat
+ parameters to control the interpretation of page content.
+ See docs/contenthandler.txt for details.

+* list=alllinks & alltransclusions now allow both 'from' and 'continue' in
+ the same query. When both are present, 'from' is simply ignored.
+* list=alllinks & alltransclusions now allow 'unique' in generators, to yield
+ a list of all link/template target pages instead of source pages.
+* BREAKING CHANGE: list=logevents output format changed for details of some log
+ types. Specifically, details that were formerly reported under a key like
+ "4::foo" will now be reported under a key of simply "foo".
+* BREAKING CHANGE: '??_badcontinue' error code was changed to '??badcontinue'
+ for all query modules.
+* ApiQueryBase adds 'badcontinue' error code if module has 'continue' parameter.
+* (bug 35885) Removed version parameter and all getVersion() methods.
+* action=options now takes a "resetkinds" option, which allows only resetting
+ certain types of preferences when the "reset" option is set.
+* (bug 36751) ApiQueryImageInfo now returns imageinfo for the redirect target
+ when queried with &redirects=.
+* (bug 31849) ApiQueryImageInfo no longer gets confused when asked for info on
+ a redirect and its target.

+ redirects.
+* On error, any warnings generated before that error will be shown in the result.
+* action=help supports generalized submodules (modules=query+value), querymodules obsolete
+* ApiQueryImageInfo continuation is more reliable. The only major change is
+ that the imagerepository property will no longer be set on page objects not
+ processed in the current query (i.e. non-images or those skipped due to
+ iicontinue).
+* Add supports for all pageset capabilities - generators, redirects, converttitles to
+ action=purge and action=setnotificationtimestamp.
+* (bug 43251) prop=pageprops&ppprop= now accepts multiple props to query.
+* ApiQueryImageInfo will now limit the number of calls to File::transform made
+ in any one query. If there are too many, iicontinue will be returned.
+* action=query&meta=siteinfo&siprop=general will now return the regexes used for
+ link trails and link prefixes. Added for Parsoid support.
+* Added an API query module list=pageswithprop, which lists pages using a
+ particular page property.
+* Added an API query module list=pagepropnames, which lists all page prop names
+ currently in use on the wiki.
+* (bug 44921) ApiMain::execute() will now return after the CORS check for an
+ HTTP OPTIONS request.
+* (bug 44923) action=upload works correctly if the entire file is uploaded in
+ the first chunk.
+* Added 'continue=' parameter to streamline client iteration over complex query results
+* (bug 44909) API parameters may now be marked as type "upload", which is now
+ used for action=upload's 'file' and 'chunk' parameters. This type will raise
+ an error during parameter validation if the parameter is given but not
+ recognized as an uploaded file.
+* (bug 44244) prop=info may now return the number of people watching each page.
+* (bug 33304) list=allpages will no longer return duplicate entries when
+ querying protection.
+* (bug 33304) list=allpages will now find really old indefinite protections.
+* (bug 45937) meta=allmessages will report a syntactically invalid lang as a
+ proper error instead of as an uncaught exception.
+* (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.
+
+=== API internal changes in 1.21 ===
+* For debugging only, a new global $wgDebugAPI removes many API restrictions when true.
+ Never use on the production servers, as this flag introduces security holes.
+ Whenever enabled, a warning will also be added to all output.
+* ApiModuleManager now handles all submodules (actions,props,lists) and instantiation
+* Query stores prop/list/meta as submodules
+* ApiPageSet can now be used in any action to process titles/pageids/revids or any generator.
+* BREAKING CHANGE: ApiPageSet constructor now has two params instead of three, with only the
+ first one keeping its meaning. ApiPageSet is now derived from ApiBase.
+* BREAKING CHANGE: ApiQuery::newGenerator() and executeGeneratorModule() were deleted.
+* ApiQueryGeneratorBase::setGeneratorMode() now requires a pageset param.
+* $wgAPIGeneratorModules is now obsolete and will be ignored.
+* Added flags ApiResult::OVERRIDE and ADD_ON_TOP to setElement() and addValue()
+* Internal API calls will now include <warnings> in case of unused parameters
+
+=== Languages updated in 1.21 ===
+
+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.
+
+* South Azerbaijani (azb) added.
+* (bug 30040) Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').
+* (bug 45436) Autonym for pi (Pali) is now 'पालि' (was ''पाळि').
+* (bug 34977) Now formatted numbers in Spanish use space as separator
+ for thousands, as mandated by the Real Academia Española.
+* (bug 35031) Kurdish formatted numbers now use period and comma
+ as separators for thousands and decimals respectively.
+
+=== Other changes in 1.21 ===
+* BREAKING CHANGE: (bug 44385) Removed the jquery.collapsibleTabs module and
+ moved it to the Vector extension. It was entirely Vector-extension-specific,
+ deeply interconnected with the extension, and this functionality really
+ belongs to the extension instead of the skin anyway. In the unlikely case you
+ were using it, you have to either copy it to your extension, or install the
+ Vector extension (and possibly disable its features using config settings if
+ you don't want them).
+* Experimental IBM DB2 support was removed due to lack of interest and maintainership
+* BREAKING CHANGE: Filenames of maintenance scripts were standardized into
+ lowerCamelCase format, and made more explicit:
+ - clear_stats.php -> clearCacheStats.php
+ - clear_interwiki_cache.php -> clearInterwikiCache.php
+ - initStats.php -> initSiteStats.php
+ - proxy_check.php -> proxyCheck.php
+ - stats.php -> showCacheStats.php
+ - showStats.php -> showSiteStats.php.
+ Class names were renamed accordingly:
+ - clear_stats -> ClearCacheStats
+ - InitStats -> InitSiteStats
+ - CacheStats -> ShowCacheStats
+ - ShowStats -> ShowSiteStats.
+* BREAKING CHANGE: (bug 38244) Removed the mediawiki.api.titleblacklist module
+ and moved it to the TitleBlacklist extension.

* (bug 26253) $wgPostCommitUpdateList has been removed
* The PHPUnit test suite has been removed from this release due to serious issues
which should be resolved by the 1.18 release.
-* Oracle DB now uses the __destruct fuction to commit/close connection as it
+* Oracle DB now uses the __destruct function to commit/close connection as it
doesn't commit on close if transation is triggered in OCI.
