+Change notes from older releases. For current info see RELEASE-NOTES-1.23.
+
+== MediaWiki 1.21 ==
+
+MediaWiki 1.21 is an alpha-quality branch and is not recommended for use in
+production.
+
+=== 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 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

+ 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.

+* 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.

+* 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.

+ currently in use on the wiki.

+ 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

+* (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.

+
+=== 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.
+
+== MediaWiki 1.20 ==
+

+Since 1.20, the lowest supported version of PHP is now 5.3.2. Please
+upgrade PHP if you have not done so prior to upgrading MediaWiki.
+
+=== Configuration changes in 1.20 ===
+* $wgGitRepositoryViewers defines a mapping from Git remote repository to the
+ Gitweb instance URL used in Special:Version.
+* `$wgUsePathInfo = true;` is no longer needed to make $wgArticlePath work on servers
+ using like nginx, lighttpd, and apache over fastcgi. MediaWiki now always extracts
+ path info from REQUEST_URI if it's available.
+* The user right 'upload_by_url' is no longer given to sysops by default.
+ This only affects installations which have $wgAllowCopyUploads set to true.

+ different timezone than the wiki timezone set by $wgLocaltimezone.

+* Added ContribsPager::reallyDoQuery hook allowing extensions to data to MyContribs
+* Added new hook ParserAfterParse to allow extensions to affect parsed output
+ after the parse is complete but before block level processing, link holder

+ internalParse method just before the parser removes unwanted/dangerous HTML tags.
