   4 == MediaWiki 1.24 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.24 ===
  12 * The server's canonical hostname is available as $wgServerName, which is
  13   exposed in both mw.config and ApiQuerySiteInfo.
  14
  15 === New features in 1.24 ===
  16 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  17   WhatLinksHere entries.
  18 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  19   a given content object.
  20 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  21 * HTMLForm's HTMLTextField now supports the 'url' type.
  22 * HTMLForm fields may now be dynamically hidden based on the values of other
  23   fields in the form.
  24 * HTMLForm now supports multiple copies of an input field or set of input
  25   fields, e.g. the form may request "one or more usernames" without having to
  26   have the user enter delimited list of names into a text field.
  27 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  28   the sidebar just before its display.
  29
  30 === Bug fixes in 1.24 ===
  31 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  32   restriction was present in the parameters.  Images with both the "frame"
  33   option and a size specification set will now always ignore the provided
  34   size and display an unscaled image, as the documentation has always
  35   claimed it would.
  36 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  37   which used to collapse some sidebar elements by default.
  38 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  39   follow redirects to their target pages.
  40 * Parser now dies early if called recursively, instead of producing subtle bugs.
  41
  42 === Web API changes in 1.24 ===
  43 * action=parse API now supports prop=modules, which provides the list of
  44   ResourceLoader modules that should be used to enhance the parsed content.
  45
  46 === Languages updated in 1.24 ===
  47
  48 MediaWiki supports over 350 languages. Many localisations are updated
  49 regularly. Below only new and removed languages are listed, as well as
  50 changes to languages because of Bugzilla reports.
  51
  52 === Other changes in 1.24 ===
  53 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  54 * The deprecated function mw.util.toggleToc was removed.
  55 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  56   were removed as they were unused.
  57 * mediawiki.util.$content no longer supports old versions of the Vector,
  58   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
  59   and/or "mw-body-primary" class name in their html.

  87 MediaWiki 1.24 requires PHP 5.3.2 or later.
  88
  89 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  90 support for them is somewhat less mature. There is experimental support for
  91 Oracle and Microsoft SQL Server.
  92
  93 The supported versions are:
  94
  95 * MySQL 5.0.2 or later
  96 * PostgreSQL 8.3 or later
  97 * SQLite 3.3.7 or later
  98 * Oracle 9.0.1 or later
  99 * Microsoft SQL Server 2005 (9.00.1399)
 100
 101 == Upgrading ==
 102
 103 1.24 has several database changes since 1.23, and will not work without schema
 104 updates. Note that due to changes to some very large tables like the revision
 105 table, the schema update may take quite long (minutes on a medium sized site,
 106 many hours on a large site).
 107
 108 If upgrading from before 1.11, and you are using a wiki as a commons
 109 repository, make sure that it is updated as well. Otherwise, errors may arise
 110 due to database schema changes.
 111
 112 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 113 new database fields are filled with data.
 114
 115 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 116 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 117 with MediaWiki 1.21.
 118
 119 Don't forget to always back up your database before upgrading!
 120
 121 See the file UPGRADE for more detailed upgrade instructions.
 122
 123 For notes on 1.22.x and older releases, see HISTORY.
