   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 * $wgAntiLockFlags was removed.
  15
  16 === New features in 1.25 ===
  17 * (bug 58139) ResourceLoaderFileModule now supports language fallback
  18   for 'languageScripts'.
  19 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
  20   parser output for a content object before links update.
  21 * (bug 35785) Enhanced recent changes and extended watchlist are now default.
  22   Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
  23   and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
  24 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
  25   in CSS. This results in slight size increase before gzip compression (due to
  26   percent-encoding), but up to 20% decrease after it.
  27
  28 === Bug fixes in 1.25 ===
  29 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  30   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  31 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  32   10- and 13-digit forms) containing "X".
  33
  34 === Action API changes in 1.25 ===
  35 * (bug 65403) XML tag highlighting is now only performed for formats
  36   "xmlfm" and "wddxfm".
  37 * action=paraminfo supports generalized submodules (modules=query+value),
  38   querymodules and formatmodules are deprecated
  39 * action=paraminfo no longer outputs descriptions and other help text by
  40   default. If needed, it may be requested using the new 'helpformat' parameter.
  41 * action=help has been completely rewritten, and outputs help in HTML
  42   rather than plain text.
  43 * Hitting api.php without specifying an action now displays only the help for
  44   the main module, with links to submodule help.
  45 * API help is no longer displayed on errors.
  46 * Internationalized messages returned by the API will be in the wiki's content
  47   language by default. 'uselang' is now a recognized API parameter;
  48   "uselang=user" may be used to select the language from the current user's
  49   preferences.
  50 * Default output format for the API is now jsonfm.
  51 * Simplified continuation will return a "batchcomplete" property in the result
  52   when a batch of pages is complete.
  53 * Pretty-printed HTML output now has nicer formatting and (if available)
  54   better syntax highlighting.
  55
  56 === Action API internal changes in 1.25 ===
  57 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  58   Most existing modules should continue working without changes, but should do
  59   the following:
  60   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  61   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  62     to replace getParamDescription(). If necessary, the settings array returned
  63     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  64     message.
  65   * Implement getExamplesMessages() to replace getExamples().
  66 * Modules with submodules (like action=query) must have their submodules
  67   override ApiBase::getParent() to return the correct parent object.
  68 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  69   and will have no effect for modules using i18n messages. Use
  70   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  71 * Api formatters will no longer be asked to display the help screen on errors.
  72 * ApiMain::getCredits() was removed. The credits are available in the
  73   'api-credits' i18n message.
  74 * ApiFormatBase has been changed to support i18n and syntax highlighting via
  75   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
  76   has been removed.
  77 * ApiFormatBase now always buffers. Output is done when
  78   ApiFormatBase::closePrinter is called.
  79 * The following methods have been deprecated and may be removed in a future
  80   release:
  81   * ApiBase::getDescription
  82   * ApiBase::getParamDescription
  83   * ApiBase::getExamples
  84   * ApiBase::makeHelpMsg
  85   * ApiBase::makeHelpArrayToString
  86   * ApiBase::makeHelpMsgParameters
  87   * ApiFormatBase::setUnescapeAmps
  88   * ApiFormatBase::getWantsHelp
  89   * ApiFormatBase::setHelp
  90   * ApiFormatBase::formatHTML
  91   * ApiFormatBase::setBufferResult
  92   * ApiFormatBase::getDescription
  93   * ApiMain::setHelp
  94   * ApiMain::reallyMakeHelpMsg
  95   * ApiMain::makeHelpMsgHeader
  96
  97 === Languages updated in 1.25 ===
  98
  99 MediaWiki supports over 350 languages. Many localisations are updated
 100 regularly. Below only new and removed languages are listed, as well as
 101 changes to languages because of Bugzilla reports.
 102
 103 === Other changes in 1.25 ===
 104 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 105   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 106   migration guide for creators and users of custom skins that relied on it.
 107 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 108 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 109   inline styles in the HTML.
 110 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 111 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 112 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 113 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 114 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 115 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 116   since 1.20)
 117 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 118   since 1.20)
 119 * Removed 'jquery.json' module. (deprecated since 1.24)
 120   Use the 'json' module and global JSON object instead.
 121 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 122   Also, the former will now throw an MWException if called with one or more
 123   arguments.
 124
 125 == Compatibility ==
 126
 127 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 128 HHVM 3.3.0.
 129
 130 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 131 support for them is somewhat less mature. There is experimental support for
 132 Oracle and Microsoft SQL Server.
 133
 134 The supported versions are:
 135
 136 * MySQL 5.0.2 or later
 137 * PostgreSQL 8.3 or later
 138 * SQLite 3.3.7 or later
 139 * Oracle 9.0.1 or later
 140 * Microsoft SQL Server 2005 (9.00.1399)
 141
 142 == Upgrading ==
 143
 144 1.25 has several database changes since 1.24, and will not work without schema
 145 updates. Note that due to changes to some very large tables like the revision
 146 table, the schema update may take quite long (minutes on a medium sized site,
 147 many hours on a large site).
 148
 149 If upgrading from before 1.11, and you are using a wiki as a commons
 150 repository, make sure that it is updated as well. Otherwise, errors may arise
 151 due to database schema changes.
 152
 153 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 154 new database fields are filled with data.
 155
 156 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 157 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 158 with MediaWiki 1.21.
 159
 160 Don't forget to always back up your database before upgrading!
 161
 162 See the file UPGRADE for more detailed upgrade instructions.
 163
 164 For notes on 1.23.x and older releases, see HISTORY.
 165
