   8 THIS IS NOT A RELEASE YET
   9
  10 MediaWiki 1.21 is an alpha-quality branch and is not recommended for use in
  11 production.
  12
  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 38110) Schema changes (adding or dropping tables, indicies and
  20   fields) can be now be done separately from from other changes that
  21   update.php makes.  This is useful in environments that use database
  22   permissions to restrict schema changes but allow the DB user that
  23   MediaWiki normally runs as to perform other changes that update.php
  24   makes.  Schema changes can be run seperately.  See the file UPGRADE
  25   for more information.
  26 * (bug 34876) jquery.makeCollapsible has been improved in performance.
  27 * Added ContentHandler facility to allow extensions to support other content than wikitext.
  28   See docs/contenthandler.txt for details.
  29 * New feature was developed for showing high-DPI thumbnails for high-DPI mobile
  30   and desktop displays (configurable with $wgResponsiveImages).
  31 * Added new backend to represent and store information about sites and site
  32   specific configuration.
  33 * jQuery upgraded from 1.8.2 to 1.8.3.
  34 * jQuery UI upgraded from 1.8.23 to 1.8.24.
  35 * Added separate fa_sha1 field to filearchive table. This allows sha1
  36   searches with the api in miser mode for deleted files.
  37 * Add initial and programmatic sorting for tablesorter.
  38 * Add the event "sortEnd.tablesorter", triggered after sorting has completed.
  39 * The Job system was refactored to allow for different backing stores for queues
  40   as well as cross-wiki access to queues, among other things. The schema for the
  41   DB queue was changed to support better concurrency and reduce deadlock errors.
  42 * Added ApiQueryORM class to facilitate creation of query API modules based on
  43   tables that have a corresponding ORMTable class.
  44 * (bug 40876) Icon for PSD (Adobe Photoshop) file types.
  45 * (bug 40641) Implemented Special:Version/Credits with a list of contributors.
  46 * (bug 7851) Implemented one-click AJAX patrolling.
  47 * The <data>, <time>, <meta>, and <link> elements are allowed within WikiText
  48   for use with Microdata.
  49 * The HTML5 <mark> tag has been whitelisted.
  50 * Added ParserCloned hook for when the Parser object is cloned.
  51 * Added AlternateEditPreview hook to allow extensions to replace the page
  52   preview from the edit page.
  53 * Added EditPage::showStandardInputs:options hook to allow extensions to add
  54   new fields to the "editOptions" area of the edit form.
  55
  56 === Bug fixes in 1.21 ===
  57 * (bug 40353) SpecialDoubleRedirect should support interwiki redirects.
  58 * (bug 40352) fixDoubleRedirects.php should support interwiki redirects.
  59 * (bug 9237) SpecialBrokenRedirect should not list interwiki redirects.
  60 * (bug 34960) Drop unused fields rc_moved_to_ns and rc_moved_to_title from
  61   recentchanges table.
  62 * (bug 32951) Do not register internal externals with absolute protocol,
  63   when server has relative protocol.
  64 * (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
  65   method requests, we now send a Host header by default, for Varnish
  66   compatibility. This also works with Squid in reverse-proxy mode. If you wish
  67   to support Squid configured in forward-proxy mode, set
  68   $wgSquidPurgeUseHostHeader to false.
  69 * (bug 37020) sql.php with readline eats semicolon.
  70 * (bug 11748) Properly handle optionally-closed HTML tags when Tidy is
  71   disabled, and don't wrap HTML-syntax definition lists in paragraphs.
  72 * (bug 41409) Diffs while editing an old revision should again diff against the
  73   current revision.
  74 * (bug 41494) Honor $wgLogExceptionBacktrace when logging non-API exceptions
  75   caught during API execution.
  76 * (bug 37963) Fixed loading process for user options.
  77 * (bug 26995) Update filename field on Upload page after having sanitized it.
  78 * (bug 41793) Contribution links to users with 0 edits on Special:ListUsers didn't
  79   show up red.
  80 * (bug 41899) A PHP notice no longer occurs when using the "rvcontinue" API parameter.
  81 * (bug 42036) Account creation emails now contain canonical (not
  82   protocol-relative) URLs.
  83 * (bug 41990) Fix regression: API edit with redirect=true and lacking
  84   starttimestamp and basetimestamp should not cause an edit conflict.
  85 * (bug 41706) EditPage: Preloaded page should be converted if possible and needed.
  86 * (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
  87   actually sorted.
  88 * (bug 2865)  User interface HTML elements don't use lang attribute
  89   (completed the fix by adding the lang attribute to firstHeading).
  90 * (bug 42173) Removed namespace prefixes on Special:UncategorizedCategories.
  91 * (bug 36053) Log in "returnto" feature forgets query parameters if no
  92   title parameter was specified.
  93
  94 === API changes in 1.21 ===
  95 * prop=revisions can now report the contentmodel and contentformat, see docs/contenthandler.txt.
  96 * action=edit and action=parse now support contentmodel and contentformat parameters to control the interpretation of
  97   page content; See docs/contenthandler.txt for details.

 105 regularly. Below only new and removed languages are listed, as well as
 106 changes to languages because of Bugzilla reports.
 107
 108 * (bug 30040) Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').
 109 * (bug 34977) Now formatted numbers in Spanish use space as separator
 110   for thousands, as mandated by the Real Academia Española.
 111 * (bug 35031) Kurdish formatted numbers now use period and comma
 112   as separators for thousands and decimals respectively.
 113
 114 === Other changes in 1.21 ===
 115
 116 == Compatibility ==
 117
 118 MediaWiki 1.21 requires PHP 5.3.2 or later.
 119
 120 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 121 support for them is somewhat less mature. There is experimental support for IBM
 122 DB2 and Oracle.
 123
 124 The supported versions are:
 125
 126 * MySQL 5.0.2 or later
 127 * PostgreSQL 8.3 or later
 128 * SQLite 3.3.7 or later
 129 * Oracle 9.0.1 or later
 130
 131 == Upgrading ==
 132
 133 1.21 has several database changes since 1.20, and will not work without schema
 134 updates. Note that due to changes to some very large tables like the revision
 135 table, the schema update may take quite long (minutes on a medium sized site,
 136 many hours on a large site).
 137
 138 If upgrading from before 1.11, and you are using a wiki as a commons
 139 repository, make sure that it is updated as well. Otherwise, errors may arise
 140 due to database schema changes.
 141
 142 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 143 new database fields are filled with data.
 144
 145 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 146 changes are made, and there is a slightly higher chance that things could
 147 break. Don't forget to always back up your database before upgrading!
 148
 149 See the file UPGRADE for more detailed upgrade instructions.
 150
 151 For notes on 1.19.x and older releases, see HISTORY.
