-Security reminder: MediaWiki does not require PHP's register_globals. If you
-have it on, turn it '''off''' if you can.
-
-== MediaWiki 1.21 ==
-
-THIS IS NOT A RELEASE YET
-
-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).
-

-* 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.

-* 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).

-  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.

-  link trails and link prefixes. Added for Parsoid support.

-  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

-  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.
-* 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.
-
-=== 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.

-  first one keeping its meaning. ApiPageSet is now derived from ApiBase.

-* $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.
-* 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).
-
-== Compatibility ==
-
-MediaWiki 1.21 requires PHP 5.3.2 or later.
-
-MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
-support for them is somewhat less mature. There is experimental support for
-Oracle.
-
-The supported versions are:
-
-* MySQL 5.0.2 or later
-* PostgreSQL 8.3 or later
-* SQLite 3.3.7 or later
-* Oracle 9.0.1 or later
-
-== Upgrading ==
-
-1.21 has several database changes since 1.20, and will not work without schema
-updates. Note that due to changes to some very large tables like the revision
-table, the schema update may take quite long (minutes on a medium sized site,
-many hours on a large site).
-
-If upgrading from before 1.11, and you are using a wiki as a commons
-repository, make sure that it is updated as well. Otherwise, errors may arise
-due to database schema changes.
-
-If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
-new database fields are filled with data.
-
-If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
-1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
-with MediaWiki 1.21.
-
-Don't forget to always back up your database before upgrading!
-
-See the file UPGRADE for more detailed upgrade instructions.
-
-For notes on 1.19.x and older releases, see HISTORY.
-
-== Online documentation ==
-
-Documentation for both end-users and site administrators is available on
-MediaWiki.org, and is covered under the GNU Free Documentation License (except
-for pages that explicitly state that their contents are in the public domain):
-
-	https://www.mediawiki.org/wiki/Documentation
-
-== Mailing list ==
-
-A mailing list is available for MediaWiki user support and discussion:
-
-	https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
-
-A low-traffic announcements-only list is also available:
-
-	https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
-
-It's highly recommended that you sign up for one of these lists if you're
-going to run a public MediaWiki, so you can be notified of security fixes.
-
-== IRC help ==
-
-There's usually someone online in #mediawiki on irc.freenode.net.
