   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 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  30   jQuery.cookie so that getting/setting a cookie is syntactically and functionally
  31   similar to using the WebRequest#getCookie/WebResponse#setcookie methods.
  32 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1.
  33
  34 === Bug fixes in 1.24 ===
  35 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  36   restriction was present in the parameters.  Images with both the "frame"
  37   option and a size specification set will now always ignore the provided
  38   size and display an unscaled image, as the documentation has always
  39   claimed it would.
  40 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  41   which used to collapse some sidebar elements by default.
  42 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  43   follow redirects to their target pages.
  44 * Parser now dies early if called recursively, instead of producing subtle bugs.
  45
  46 === Web API changes in 1.24 ===
  47 * action=parse API now supports prop=modules, which provides the list of
  48   ResourceLoader modules that should be used to enhance the parsed content.
  49
  50 === Languages updated in 1.24 ===
  51
  52 MediaWiki supports over 350 languages. Many localisations are updated
  53 regularly. Below only new and removed languages are listed, as well as
  54 changes to languages because of Bugzilla reports.
  55
  56 === Other changes in 1.24 ===
  57 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  58 * The deprecated function mw.util.toggleToc was removed.
  59 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  60   were removed as they were unused.
  61 * mediawiki.util.$content no longer supports old versions of the Vector,
  62   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
  63   and/or "mw-body-primary" class name in their html.

  90 == Compatibility ==
  91
  92 MediaWiki 1.24 requires PHP 5.3.2 or later.
  93
  94 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  95 support for them is somewhat less mature. There is experimental support for
  96 Oracle and Microsoft SQL Server.
  97
  98 The supported versions are:
  99
 100 * MySQL 5.0.2 or later
 101 * PostgreSQL 8.3 or later
 102 * SQLite 3.3.7 or later
 103 * Oracle 9.0.1 or later
 104 * Microsoft SQL Server 2005 (9.00.1399)
 105
 106 == Upgrading ==
 107
 108 1.24 has several database changes since 1.23, and will not work without schema
 109 updates. Note that due to changes to some very large tables like the revision
 110 table, the schema update may take quite long (minutes on a medium sized site,
 111 many hours on a large site).
 112
 113 If upgrading from before 1.11, and you are using a wiki as a commons
 114 repository, make sure that it is updated as well. Otherwise, errors may arise
 115 due to database schema changes.
 116
 117 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 118 new database fields are filled with data.
 119
 120 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 121 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 122 with MediaWiki 1.21.
 123
 124 Don't forget to always back up your database before upgrading!
 125
 126 See the file UPGRADE for more detailed upgrade instructions.
 127
 128 For notes on 1.22.x and older releases, see HISTORY.
