  12 === Configuration changes in 1.21 ===

  15   instead.
  16
  17 === New features in 1.21 ===
  18 * (bug 34876) jquery.makeCollapsible has been improved in performance.
  19 * Added ContentHandler facility to allow extensions to support other content
  20   than wikitext. See docs/contenthandler.txt for details.
  21 * New feature was developed for showing high-DPI thumbnails for high-DPI mobile
  22   and desktop displays (configurable with $wgResponsiveImages).
  23 * Added new backend to represent and store information about sites and site
  24   specific configuration.

  26 * jQuery UI upgraded from 1.8.23 to 1.8.24.

  28   searches with the api in miser mode for deleted files.
  29 * Add initial and programmatic sorting for tablesorter.
  30 * Add the event "sortEnd.tablesorter", triggered after sorting has completed.
  31 * The Job system was refactored to allow for different backing stores for
  32   queues as well as cross-wiki access to queues, among other things. The schema
  33   for the DB queue was changed to support better concurrency and reduce
  34   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.

  41   for use with Microdata.

  44 * Added AlternateEditPreview hook to allow extensions to replace the page
  45   preview from the edit page.
  46 * Added EditPage::showStandardInputs:options hook to allow extensions to add
  47   new fields to the "editOptions" area of the edit form.

  49 === Bug fixes in 1.21 ===
  50 * (bug 40353) SpecialDoubleRedirect should support interwiki redirects.
  51 * (bug 40352) fixDoubleRedirects.php should support interwiki redirects.
  52 * (bug 9237) SpecialBrokenRedirect should not list interwiki redirects.
  53 * (bug 34960) Drop unused fields rc_moved_to_ns and rc_moved_to_title from

  56   when server has relative protocol.
  57 * (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
  58   method requests, we now send a Host header by default, for Varnish
  59   compatibility. This also works with Squid in reverse-proxy mode. If you wish
  60   to support Squid configured in forward-proxy mode, set
  61   $wgSquidPurgeUseHostHeader to false.
  62 * (bug 37020) sql.php with readline eats semicolon.
  63 * (bug 11748) Properly handle optionally-closed HTML tags when Tidy is
  64   disabled, and don't wrap HTML-syntax definition lists in paragraphs.
  65 * (bug 41409) Diffs while editing an old revision should again diff against the
  66   current revision.
  67 * (bug 41494) Honor $wgLogExceptionBacktrace when logging non-API exceptions
  68   caught during API execution.
  69 * (bug 37963) Fixed loading process for user options.
  70 * (bug 26995) Update filename field on Upload page after having sanitized it.
  71 * (bug 41793) Contribution links to users with 0 edits on Special:ListUsers
  72   didn't show up red.
  73 * (bug 41899) A PHP notice no longer occurs when using the "rvcontinue" API
  74   parameter.
  75 * (bug 42036) Account creation emails now contain canonical (not
  76   protocol-relative) URLs.
  77 * (bug 41990) Fix regression: API edit with redirect=true and lacking
  78   starttimestamp and basetimestamp should not cause an edit conflict.
  79 * (bug 41706) EditPage: Preloaded page should be converted if possible and
  80   needed.
  81 * (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
  82   actually sorted.
  83 * (bug 2865)  User interface HTML elements don't use lang attribute
  84   (completed the fix by adding the lang attribute to firstHeading).
  85 * (bug 42173) Removed namespace prefixes on Special:UncategorizedCategories.
  86 * (bug 36053) Log in "returnto" feature forgets query parameters if no
  87   title parameter was specified.
  88 * (bug 42410) API action=edit now returns correct timestamp for the new edit.
  89 * (bug 14901) Email notification mistakes log action for new page creation.
  90   Enotif no longer sends "page has been created" notifications for some log
  91   actions. The following events now have a correct message: page creation,
  92   deletion, move, restore (undeletion), change (edit).
  93 * (bug 457) In the sidebar of Vector, CologneBlue, Monobook, and Monobook-based
  94   skins, the heading levels have been changed from (variously per skin)
  95   <h4>, <h5> or <h6> to only <h3>s, with a <h2> hidden heading above them.
  96   If you are styling or scripting the headings in a custom way, this change
  97   will require updates to your site's CSS or JS.
  98
  99 === API changes in 1.21 ===
 100 * prop=revisions can now report the contentmodel and contentformat.
 101   See docs/contenthandler.txt.
 102 * action=edit and action=parse now support contentmodel and contentformat
 103   parameters to control the interpretation of page content.
 104   See docs/contenthandler.txt for details.
 105 * (bug 35693) ApiQueryImageInfo now suppresses errors when unserializing metadata.

 108   does not exist.
 109

 113 regularly. Below only new and removed languages are listed, as well as
 114 changes to languages because of Bugzilla reports.

 121
 122 === Other changes in 1.21 ===
 123
 124 == Compatibility ==
 125
 126 MediaWiki 1.21 requires PHP 5.3.2 or later.
 127
 128 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 129 support for them is somewhat less mature. There is experimental support for IBM
 130 DB2 and Oracle.
 131
 132 The supported versions are:
 133
 134 * MySQL 5.0.2 or later
 135 * PostgreSQL 8.3 or later
 136 * SQLite 3.3.7 or later
 137 * Oracle 9.0.1 or later
 138
 139 == Upgrading ==
 140
 141 1.21 has several database changes since 1.20, and will not work without schema
 142 updates. Note that due to changes to some very large tables like the revision
 143 table, the schema update may take quite long (minutes on a medium sized site,
 144 many hours on a large site).
 145
 146 If upgrading from before 1.11, and you are using a wiki as a commons
 147 repository, make sure that it is updated as well. Otherwise, errors may arise
 148 due to database schema changes.
 149
 150 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 151 new database fields are filled with data.
 152
 153 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 154 changes are made, and there is a slightly higher chance that things could
 155 break. Don't forget to always back up your database before upgrading!
 156
 157 See the file UPGRADE for more detailed upgrade instructions.
 158
 159 For notes on 1.19.x and older releases, see HISTORY.
