  13 === Configuration changes in 1.21 ===
  14 * (bug 29374) $wgVectorUseSimpleSearch is now enabled by default.
  15 * Deprecated $wgAllowRealName is removed. Use $wgHiddenPrefs[] = 'realname'
  16   instead.
  17
  18 === New features in 1.21 ===
  19 * (bug 34876) jquery.makeCollapsible has been improved in performance.
  20 * Added ContentHandler facility to allow extensions to support other content than wikitext.
  21   See docs/contenthandler.txt for details.
  22 * New feature was developed for showing high-DPI thumbnails for high-DPI mobile
  23   and desktop displays (configurable with $wgResponsiveImages).
  24 * Added new backend to represent and store information about sites and site
  25   specific configuration.
  26 * jQuery upgraded from 1.8.2 to 1.8.3.
  27 * jQuery UI upgraded from 1.8.23 to 1.8.24.
  28 * Added separate fa_sha1 field to filearchive table. This allows sha1
  29   searches with the api in miser mode for deleted files.
  30 * Add initial and programmatic sorting for tablesorter.
  31 * Add the event "sortEnd.tablesorter", triggered after sorting has completed.
  32 * The Job system was refactored to allow for different backing stores for queues
  33   as well as cross-wiki access to queues, among other things. The schema for the
  34   DB queue was changed to support better concurrency and reduce deadlock errors.
  35 * Added ApiQueryORM class to facilitate creation of query API modules based on
  36   tables that have a corresponding ORMTable class.
  37 * (bug 40876) Icon for PSD (Adobe Photoshop) file types.
  38 * (bug 40641) Implemented Special:Version/Credits with a list of contributors.
  39 * (bug 7851) Implemented one-click AJAX patrolling.
  40 * The <data>, <time>, <meta>, and <link> elements are allowed within WikiText
  41   for use with Microdata.
  42 * The HTML5 <mark> tag has been whitelisted.
  43
  44 === Bug fixes in 1.21 ===
  45 * (bug 40353) SpecialDoubleRedirect should support interwiki redirects.
  46 * (bug 40352) fixDoubleRedirects.php should support interwiki redirects.

  49   recentchanges table.
  50 * (bug 32951) Do not register internal externals with absolute protocol,
  51   when server has relative protocol.
  52 * (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
  53   method requests, we now send a Host header by default, for Varnish
  54   compatibility. This also works with Squid in reverse-proxy mode. If you wish
  55   to support Squid configured in forward-proxy mode, set
  56   $wgSquidPurgeUseHostHeader to false.
  57 * (bug 37020) sql.php with readline eats semicolon
  58 * (bug 11748) Properly handle optionally-closed HTML tags when Tidy is

  60 * (bug 41409) Diffs while editing an old revision should again diff against the
  61   current revision.
  62 * (bug 41494) Honor $wgLogExceptionBacktrace when logging non-API exceptions
  63   caught during API execution.

  67   show up red.

  69 * (bug 42036) Account creation emails now contain canonical (not
  70   protocol-relative) URLs.
  71 * (bug 41990) Fix regression: API edit with redirect=true and lacking
  72   starttimestamp and basetimestamp should not cause an edit conflict.
  73 * (bug 41706) EditPage: Preloaded page should be converted if possible and needed.
  74 * (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
  75   actually sorted.
  76 * (bug 2865)  User interface HTML elements don't use lang attribute
  77   (completed the fix by adding the lang attribute to firstHeading)
  78 * (bug 42173) Removed namespace prefixes on Special:UncategorizedCategories.
  79
  80 === API changes in 1.21 ===
  81 * prop=revisions can now report the contentmodel and contentformat, see docs/contenthandler.txt

  83   page content; See docs/contenthandler.txt for details.
  84 * (bug 35693) ApiQueryImageInfo now suppresses errors when unserializing metadata.

  88 === Languages updated in 1.21 ===
  89
  90 MediaWiki supports over 350 languages. Many localisations are updated
  91 regularly. Below only new and removed languages are listed, as well as
  92 changes to languages because of Bugzilla reports.
  93 === Other changes in 1.21 ===
  94
  95 == Compatibility ==
  96
  97 MediaWiki 1.21 requires PHP 5.3.2 or later.
  98
  99 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 100 support for them is somewhat less mature. There is experimental support for IBM
 101 DB2 and Oracle.
 102
 103 The supported versions are:
 104
 105 * MySQL 5.0.2 or later
 106 * PostgreSQL 8.3 or later
 107 * SQLite 3.3.7 or later
 108 * Oracle 9.0.1 or later
 109
 110 == Upgrading ==
 111
 112 1.21 has several database changes since 1.20, and will not work without schema
 113 updates. Note that due to changes to some very large tables like the revision
 114 table, the schema update may take quite long (minutes on a medium sized site,
 115 many hours on a large site).
 116
 117 If upgrading from before 1.11, and you are using a wiki as a commons
 118 repository, make sure that it is updated as well. Otherwise, errors may arise
 119 due to database schema changes.
 120
 121 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 122 new database fields are filled with data.
 123
 124 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 125 changes are made, and there is a slightly higher chance that things could
 126 break. Don't forget to always back up your database before upgrading!
 127
 128 See the file UPGRADE for more detailed upgrade instructions.
 129
 130 For notes on 1.19.x and older releases, see HISTORY.
