   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 * Upgrade jStorage to v0.4.12.
  28
  29 === Bug fixes in 1.25 ===
  30 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  31   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  32 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  33   10- and 13-digit forms) containing "X".
  34
  35 === Action API changes in 1.25 ===
  36 * (bug 65403) XML tag highlighting is now only performed for formats
  37   "xmlfm" and "wddxfm".
  38 * action=paraminfo supports generalized submodules (modules=query+value),
  39   querymodules and formatmodules are deprecated
  40 * action=paraminfo no longer outputs descriptions and other help text by
  41   default. If needed, it may be requested using the new 'helpformat' parameter.
  42 * action=help has been completely rewritten, and outputs help in HTML
  43   rather than plain text.
  44 * Hitting api.php without specifying an action now displays only the help for
  45   the main module, with links to submodule help.
  46 * API help is no longer displayed on errors.
  47 * Internationalized messages returned by the API will be in the wiki's content
  48   language by default. 'uselang' is now a recognized API parameter;
  49   "uselang=user" may be used to select the language from the current user's
  50   preferences.
  51 * Default output format for the API is now jsonfm.
  52 * Simplified continuation will return a "batchcomplete" property in the result
  53   when a batch of pages is complete.
  54 * Pretty-printed HTML output now has nicer formatting and (if available)
  55   better syntax highlighting.
  56
  57 === Action API internal changes in 1.25 ===
  58 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  59   Most existing modules should continue working without changes, but should do
  60   the following:
  61   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  62   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  63     to replace getParamDescription(). If necessary, the settings array returned
  64     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  65     message.
  66   * Implement getExamplesMessages() to replace getExamples().
  67 * Modules with submodules (like action=query) must have their submodules
  68   override ApiBase::getParent() to return the correct parent object.
  69 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  70   and will have no effect for modules using i18n messages. Use
  71   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  72 * Api formatters will no longer be asked to display the help screen on errors.
  73 * ApiMain::getCredits() was removed. The credits are available in the
  74   'api-credits' i18n message.
  75 * ApiFormatBase has been changed to support i18n and syntax highlighting via
  76   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
  77   has been removed.
  78 * ApiFormatBase now always buffers. Output is done when
  79   ApiFormatBase::closePrinter is called.
  80 * The following methods have been deprecated and may be removed in a future
  81   release:
  82   * ApiBase::getDescription
  83   * ApiBase::getParamDescription
  84   * ApiBase::getExamples
  85   * ApiBase::makeHelpMsg
  86   * ApiBase::makeHelpArrayToString
  87   * ApiBase::makeHelpMsgParameters
  88   * ApiFormatBase::setUnescapeAmps
  89   * ApiFormatBase::getWantsHelp
  90   * ApiFormatBase::setHelp
  91   * ApiFormatBase::formatHTML
  92   * ApiFormatBase::setBufferResult
  93   * ApiFormatBase::getDescription
  94   * ApiMain::setHelp
  95   * ApiMain::reallyMakeHelpMsg
  96   * ApiMain::makeHelpMsgHeader
  97
  98 === Languages updated in 1.25 ===
  99
 100 MediaWiki supports over 350 languages. Many localisations are updated
 101 regularly. Below only new and removed languages are listed, as well as
 102 changes to languages because of Bugzilla reports.
 103
 104 === Other changes in 1.25 ===
 105 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 106   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 107   migration guide for creators and users of custom skins that relied on it.
 108 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 109 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 110   inline styles in the HTML.
 111 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 112 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 113 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 114 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 115 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 116 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 117   since 1.20)
 118 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 119   since 1.20)
 120 * Removed 'jquery.json' module. (deprecated since 1.24)
 121   Use the 'json' module and global JSON object instead.
 122 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 123   Also, the former will now throw an MWException if called with one or more
 124   arguments.
 125
 126 == Compatibility ==
 127
 128 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 129 HHVM 3.3.0.
 130
 131 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 132 support for them is somewhat less mature. There is experimental support for
 133 Oracle and Microsoft SQL Server.
 134
 135 The supported versions are:
 136
 137 * MySQL 5.0.2 or later
 138 * PostgreSQL 8.3 or later
 139 * SQLite 3.3.7 or later
 140 * Oracle 9.0.1 or later
 141 * Microsoft SQL Server 2005 (9.00.1399)
 142
 143 == Upgrading ==
 144
 145 1.25 has several database changes since 1.24, and will not work without schema
 146 updates. Note that due to changes to some very large tables like the revision
 147 table, the schema update may take quite long (minutes on a medium sized site,
 148 many hours on a large site).
 149
 150 If upgrading from before 1.11, and you are using a wiki as a commons
 151 repository, make sure that it is updated as well. Otherwise, errors may arise
 152 due to database schema changes.
 153
 154 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 155 new database fields are filled with data.
 156
 157 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 158 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 159 with MediaWiki 1.21.
 160
 161 Don't forget to always back up your database before upgrading!
 162
 163 See the file UPGRADE for more detailed upgrade instructions.
 164
 165 For notes on 1.23.x and older releases, see HISTORY.
