   1 Security reminder: If you have PHP's register_globals option set, you must

   4 == MediaWiki 1.25 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.25 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.25 ===
  12 * $wgPageShowWatchingUsers was removed.
  13 * $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
  14 * $wgAntiLockFlags was removed.
  15
  16 === New features in 1.25 ===
  17 * (bug 58139) ResourceLoaderFileModule now supports language fallback
  18   for 'languageScripts'.
  19 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
  20   parser output for a content object before links update.
  21 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
  22   in CSS. This results in slight size increase before gzip compression (due to
  23   percent-encoding), but up to 20% decrease after it.
  24
  25 === Bug fixes in 1.25 ===
  26 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  27   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  28 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  29   10- and 13-digit forms) containing "X".
  30
  31 === Action API changes in 1.25 ===
  32 * (bug 65403) XML tag highlighting is now only performed for formats
  33   "xmlfm" and "wddxfm".
  34 * action=paraminfo supports generalized submodules (modules=query+value),
  35   querymodules and formatmodules are deprecated
  36 * action=paraminfo no longer outputs descriptions and other help text by
  37   default. If needed, it may be requested using the new 'helpformat' parameter.
  38 * action=help has been completely rewritten, and outputs help in HTML
  39   rather than plain text.
  40 * Hitting api.php without specifying an action now displays only the help for
  41   the main module, with links to submodule help.
  42 * API help is no longer displayed on errors.
  43 * Internationalized messages returned by the API will be in the wiki's content
  44   language by default. 'uselang' is now a recognized API parameter;
  45   "uselang=user" may be used to select the language from the current user's
  46   preferences.
  47
  48 === Action API internal changes in 1.25 ===
  49 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  50   Most existing modules should continue working without changes, but should do
  51   the following:
  52   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  53   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  54     to replace getParamDescription(). If necessary, the settings array returned
  55     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  56     message.
  57   * Implement getExamplesMessages() to replace getExamples().
  58 * Modules with submodules (like action=query) must have their submodules
  59   override ApiBase::getParent() to return the correct parent object.
  60 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  61   and will have no effect for modules using i18n messages. Use
  62   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  63 * Api formatters will no longer be asked to display the help screen on errors.
  64 * ApiMain::getCredits() was removed. The credits are available in the
  65   'api-credits' i18n message.
  66 * The following methods have been deprecated and may be removed in a future
  67   release:
  68   * ApiBase::getDescription
  69   * ApiBase::getParamDescription
  70   * ApiBase::getExamples
  71   * ApiBase::makeHelpMsg
  72   * ApiBase::makeHelpArrayToString
  73   * ApiBase::makeHelpMsgParameters
  74   * ApiFormatBase::setUnescapeAmps
  75   * ApiFormatBase::getWantsHelp
  76   * ApiFormatBase::setHelp
  77   * ApiMain::setHelp
  78   * ApiMain::reallyMakeHelpMsg
  79   * ApiMain::makeHelpMsgHeader
  80
  81 === Languages updated in 1.25 ===
  82
  83 MediaWiki supports over 350 languages. Many localisations are updated
  84 regularly. Below only new and removed languages are listed, as well as
  85 changes to languages because of Bugzilla reports.
  86
  87 === Other changes in 1.25 ===
  88 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
  89   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
  90   migration guide for creators and users of custom skins that relied on it.
  91 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
  92 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
  93   inline styles in the HTML.
  94 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
  95 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
  96 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
  97 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
  98 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
  99 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 100   since 1.20)
 101 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 102   since 1.20)
 103 * Removed 'jquery.json' module. (deprecated since 1.24)
 104   Use the 'json' module and global JSON object instead.
 105 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 106   Also, the former will now throw an MWException if called with one or more
 107   arguments.
 108
 109 == Compatibility ==
 110
 111 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 112 HHVM 3.3.0.
 113
 114 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 115 support for them is somewhat less mature. There is experimental support for
 116 Oracle and Microsoft SQL Server.
 117
 118 The supported versions are:
 119
 120 * MySQL 5.0.2 or later
 121 * PostgreSQL 8.3 or later
 122 * SQLite 3.3.7 or later
 123 * Oracle 9.0.1 or later
 124 * Microsoft SQL Server 2005 (9.00.1399)
 125
 126 == Upgrading ==
 127
 128 1.25 has several database changes since 1.24, and will not work without schema
 129 updates. Note that due to changes to some very large tables like the revision
 130 table, the schema update may take quite long (minutes on a medium sized site,
 131 many hours on a large site).
 132
 133 If upgrading from before 1.11, and you are using a wiki as a commons
 134 repository, make sure that it is updated as well. Otherwise, errors may arise
 135 due to database schema changes.
 136
 137 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 138 new database fields are filled with data.
 139
 140 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 141 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 142 with MediaWiki 1.21.
 143
 144 Don't forget to always back up your database before upgrading!
 145
 146 See the file UPGRADE for more detailed upgrade instructions.
 147
 148 For notes on 1.23.x and older releases, see HISTORY.
