   6
   7 THIS IS NOT A RELEASE YET
   8
   9 MediaWiki 1.21 is an alpha-quality branch and is not recommended for use in
  10 production.
  11
  12 === Configuration changes in 1.21 ===
  13 * (bug 29374) $wgVectorUseSimpleSearch is now enabled by default.
  14 * Deprecated $wgAllowRealName is removed. Use $wgHiddenPrefs[] = 'realname'
  15   instead.
  16
  17 === New features in 1.21 ===
  18 * (bug 38110) Schema changes (adding or dropping tables, indicies and
  19   fields) can be now be done separately from from other changes that
  20   update.php makes.  This is useful in environments that use database
  21   permissions to restrict schema changes but allow the DB user that
  22   MediaWiki normally runs as to perform other changes that update.php
  23   makes.  Schema changes can be run seperately.  See the file UPGRADE
  24   for more information.
  25 * (bug 34876) jquery.makeCollapsible has been improved in performance.
  26 * Added ContentHandler facility to allow extensions to support other content
  27   than wikitext. See docs/contenthandler.txt for details.
  28 * New feature was developed for showing high-DPI thumbnails for high-DPI mobile
  29   and desktop displays (configurable with $wgResponsiveImages).
  30 * Added new backend to represent and store information about sites and site
  31   specific configuration.
  32 * jQuery upgraded from 1.8.2 to 1.8.3.
  33 * jQuery UI upgraded from 1.8.23 to 1.8.24.
  34 * Added separate fa_sha1 field to filearchive table. This allows sha1
  35   searches with the api in miser mode for deleted files.
  36 * Add initial and programmatic sorting for tablesorter.
  37 * Add the event "sortEnd.tablesorter", triggered after sorting has completed.
  38 * The Job system was refactored to allow for different backing stores for
  39   queues as well as cross-wiki access to queues, among other things. The schema
  40   for the DB queue was changed to support better concurrency and reduce
  41   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 * Upload stash DB schema altered to improve upload performance.
  56 * The following global functions are now reporting deprecated warnings in
  57   debug mode: wfMsg, wfMsgNoTrans, wfMsgForContent, wfMsgForContentNoTrans,
  58   wfMsgReal, wfMsgGetKey, wfMsgHtml, wfMsgWikiHtml, wfMsgExt, wfEmptyMsg. Use
  59   the Message class, or the global method wfMessage.
  60 * Debug message emitted by wfDebugLog() will now be prefixed with the group
  61   name when its logged to the default log file. That is the case whenever the
  62   group has no key in wgDebugLogGroups, that will help triage the default log.
  63 * (bug 24620) Add types to LogFormatter.
  64 * jQuery JSON upgraded from 2.3 to 2.4.0.
  65
  66 === Bug fixes in 1.21 ===
  67 * (bug 40353) SpecialDoubleRedirect should support interwiki redirects.
  68 * (bug 40352) fixDoubleRedirects.php should support interwiki redirects.
  69 * (bug 9237) SpecialBrokenRedirect should not list interwiki redirects.
  70 * (bug 34960) Drop unused fields rc_moved_to_ns and rc_moved_to_title from
  71   recentchanges table.
  72 * (bug 32951) Do not register internal externals with absolute protocol,
  73   when server has relative protocol.
  74 * (bug 39005) When purging proxies listed in $wgSquidServers using HTTP PURGE
  75   method requests, we now send a Host header by default, for Varnish
  76   compatibility. This also works with Squid in reverse-proxy mode. If you wish
  77   to support Squid configured in forward-proxy mode, set
  78   $wgSquidPurgeUseHostHeader to false.
  79 * (bug 37020) sql.php with readline eats semicolon.
  80 * (bug 11748) Properly handle optionally-closed HTML tags when Tidy is
  81   disabled, and don't wrap HTML-syntax definition lists in paragraphs.
  82 * (bug 41409) Diffs while editing an old revision should again diff against the
  83   current revision.
  84 * (bug 41494) Honor $wgLogExceptionBacktrace when logging non-API exceptions
  85   caught during API execution.
  86 * (bug 37963) Fixed loading process for user options.
  87 * (bug 26995) Update filename field on Upload page after having sanitized it.
  88 * (bug 41793) Contribution links to users with 0 edits on Special:ListUsers
  89   didn't show up red.
  90 * (bug 41899) A PHP notice no longer occurs when using the "rvcontinue" API
  91   parameter.
  92 * (bug 42036) Account creation emails now contain canonical (not
  93   protocol-relative) URLs.
  94 * (bug 41990) Fix regression: API edit with redirect=true and lacking
  95   starttimestamp and basetimestamp should not cause an edit conflict.
  96 * (bug 41706) EditPage: Preloaded page should be converted if possible and
  97   needed.
  98 * (bug 41886) Rowspans are no longer exploded by tablesorter until the table is
  99   actually sorted.
 100 * (bug 2865)  User interface HTML elements don't use lang attribute
 101   (completed the fix by adding the lang attribute to firstHeading).
 102 * (bug 42173) Removed namespace prefixes on Special:UncategorizedCategories.
 103 * (bug 36053) Log in "returnto" feature forgets query parameters if no
 104   title parameter was specified.
 105 * (bug 42410) API action=edit now returns correct timestamp for the new edit.
 106 * (bug 14901) Email notification mistakes log action for new page creation.
 107   Enotif no longer sends "page has been created" notifications for some log
 108   actions. The following events now have a correct message: page creation,
 109   deletion, move, restore (undeletion), change (edit).
 110 * (bug 457) In the sidebar of Vector, CologneBlue, Monobook, and Monobook-based
 111   skins, the heading levels have been changed from (variously per skin)
 112   <h4>, <h5> or <h6> to only <h3>s, with a <h2> hidden heading above them.
 113   If you are styling or scripting the headings in a custom way, this change
 114   will require updates to your site's CSS or JS.
 115
 116 === API changes in 1.21 ===
 117 * prop=revisions can now report the contentmodel and contentformat.
 118   See docs/contenthandler.txt.
 119 * action=edit and action=parse now support contentmodel and contentformat
 120   parameters to control the interpretation of page content.
 121   See docs/contenthandler.txt for details.
 122 * (bug 35693) ApiQueryImageInfo now suppresses errors when unserializing metadata.
 123 * (bug 40111) Disable minor edit for page/section creation by API.

 125   does not exist.
 126 * (bug 27202) Add timestamp sort to list=allimages.
 127
 128 === Languages updated in 1.21 ===

 131 regularly. Below only new and removed languages are listed, as well as
 132 changes to languages because of Bugzilla reports.
 133
 134 * South Azerbaijani (azb) added.
 135 * (bug 30040) Autonym for nds-nl is now 'Nedersaksies' (was 'Nedersaksisch').

 137   for thousands, as mandated by the Real Academia Española.
 138 * (bug 35031) Kurdish formatted numbers now use period and comma
 139   as separators for thousands and decimals respectively.
 140
 141 === Other changes in 1.21 ===
 142
 143 == Compatibility ==
 144
 145 MediaWiki 1.21 requires PHP 5.3.2 or later.
 146
 147 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 148 support for them is somewhat less mature. There is experimental support for IBM
 149 DB2 and Oracle.
 150
 151 The supported versions are:
 152
 153 * MySQL 5.0.2 or later
 154 * PostgreSQL 8.3 or later
 155 * SQLite 3.3.7 or later
 156 * Oracle 9.0.1 or later
 157
 158 == Upgrading ==
 159
 160 1.21 has several database changes since 1.20, and will not work without schema
 161 updates. Note that due to changes to some very large tables like the revision
 162 table, the schema update may take quite long (minutes on a medium sized site,
 163 many hours on a large site).
 164
 165 If upgrading from before 1.11, and you are using a wiki as a commons
 166 repository, make sure that it is updated as well. Otherwise, errors may arise
 167 due to database schema changes.
 168
 169 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 170 new database fields are filled with data.
 171
 172 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 173 changes are made, and there is a slightly higher chance that things could
 174 break. Don't forget to always back up your database before upgrading!
 175
 176 See the file UPGRADE for more detailed upgrade instructions.
 177
 178 For notes on 1.19.x and older releases, see HISTORY.
