+ 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 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.
-MediaWiki 1.21 is an alpha-quality branch and is not recommended for use in
-production.
+* Batak Toba (bbc-latn) added.
+* (bug 46751) Made Buryat (Russia) (бÑÑÑад) (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
