1.21 での新機能

 * Add parser method to call parser functions.
 * 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.
 * 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.
 * Icon for PSD (Adobe Photoshop) file types.
 * Implemented Special:Version/Credits with a list of contributors.
 * Implemented one-click AJAX patrolling.
 * The &lt;data&gt;, &lt;time&gt;, &lt;meta&gt;, and &lt;link&gt; elements are allowed within WikiText for use with Microdata.
 * The HTML5 &lt;mark&gt; 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 &lt;link rel=canonical&gt; 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.
 * 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.
 * 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.
 * 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.
 * 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.
 * Categories that are redirects will be displayed italic in the category links section at the bottom of a page.
 * 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.
 * 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-&lt;langcode&gt;', where &lt;langcode&gt; 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.
 * Add image rotation api "imagerotate"
 * Add "User rights management" link on user page toolbox.
 * 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).

 * BREAKING CHANGE
 * Chunked uploads are now disabled by default. You can re-enable them by setting $wgAllowChunkedUploads=true


 * 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.


 * prop=revisions can now report the contentmodel and contentformat. See docs/contenthandler.txt.

 * ApiQueryImageInfo no longer throws exceptions with ForeignDBRepo 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

 * Add supports for all pageset capabilities - generators, redirects, converttitles to action=purge and action=setnotificationtimestamp.
 * 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.

 * Added 'continue=' parameter to streamline client iteration over complex query results
 * 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.
 * prop=info may now return the number of people watching each page.
 * list=allpages will no longer return duplicate entries when querying protection.
 * list=allpages will now find really old indefinite protections.
 * meta=allmessages will report a syntactically invalid lang as a proper error instead of as an uncaught exception.
 * SpecialStatistics::getOtherStats now uses the user language.

1.21 での API の内部的な変更点

 * BREAKING CHANGE
 * ApiQuery::newGenerator and executeGeneratorModule were deleted.


 * 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.

1.21 で更新された言語
MediaWiki は 350 以上の言語に対応しています. 多くの地域化は定期的に更新されています. 以下では新しい言語および除去された言語のみを列挙しています. Bugzilla での報告に基づいて変更された言語も併せて列挙しています.


 * 南アゼルバイジャン語 (azb) を追加しました.
 * Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').
 * Autonym for pi (Pali) is now 'पालि' (was 'पाळि').
 * Now formatted numbers in Spanish use space as separator for thousands, as mandated by the Real Academia Española.
 * Kurdish formatted numbers now use period and comma as separators for thousands and decimals respectively.

1.21 でのその他の変更点

 * Experimental IBM DB2 support was removed due to lack of interest and maintainership.
 * BREAKING CHANGE
 * 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).


 * BREAKING CHANGE
 * Filenames of maintenance scripts were standardized into lowerCamelCase format, and made more explicit:
 * clear_stats.php &rarr; clearCacheStats.php
 * clear_interwiki_cache.php &rarr; clearInterwikiCache.php
 * initStats.php &rarr; initSiteStats.php
 * proxy_check.php &rarr; proxyCheck.php
 * stats.php &rarr; showCacheStats.php
 * showStats.php &rarr; showSiteStats.php.
 * Class names were renamed accordingly:
 * clear_stats &rarr; ClearCacheStats
 * InitStats &rarr; InitSiteStats
 * CacheStats &rarr; ShowCacheStats
 * ShowStats &rarr; ShowSiteStats.


 * BREAKING CHANGE
 * Removed the mediawiki.api.titleblacklist module and moved it to the TitleBlacklist extension.

互換性
MediaWiki 1.21 は PHP 5.3.2 以降を必要とします.

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.

対応しているバージョン:


 * MySQL 5.0.2 以降
 * PostgreSQL 8.3 以降
 * SQLite 3.3.7 以降
 * Oracle 9.0.1 以降

アップグレード
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.

アップグレードする前に、必ずバックアップを作成してください!
