   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 * Default output format for the API is now jsonfm.
  48 * Simplified continuation will return a "batchcomplete" property in the result
  49   when a batch of pages is complete.
  50
  51 === Action API internal changes in 1.25 ===
  52 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  53   Most existing modules should continue working without changes, but should do
  54   the following:
  55   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  56   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  57     to replace getParamDescription(). If necessary, the settings array returned
  58     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  59     message.
  60   * Implement getExamplesMessages() to replace getExamples().
  61 * Modules with submodules (like action=query) must have their submodules
  62   override ApiBase::getParent() to return the correct parent object.
  63 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  64   and will have no effect for modules using i18n messages. Use
  65   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  66 * Api formatters will no longer be asked to display the help screen on errors.
  67 * ApiMain::getCredits() was removed. The credits are available in the
  68   'api-credits' i18n message.
  69 * The following methods have been deprecated and may be removed in a future
  70   release:
  71   * ApiBase::getDescription
  72   * ApiBase::getParamDescription
  73   * ApiBase::getExamples
  74   * ApiBase::makeHelpMsg
  75   * ApiBase::makeHelpArrayToString
  76   * ApiBase::makeHelpMsgParameters
  77   * ApiFormatBase::setUnescapeAmps
  78   * ApiFormatBase::getWantsHelp
  79   * ApiFormatBase::setHelp
  80   * ApiMain::setHelp
  81   * ApiMain::reallyMakeHelpMsg
  82   * ApiMain::makeHelpMsgHeader
  83
  84 === Languages updated in 1.25 ===
  85
  86 MediaWiki supports over 350 languages. Many localisations are updated
  87 regularly. Below only new and removed languages are listed, as well as
  88 changes to languages because of Bugzilla reports.
  89
  90 === Other changes in 1.25 ===
  91 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
  92   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
  93   migration guide for creators and users of custom skins that relied on it.
  94 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
  95 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
  96   inline styles in the HTML.
  97 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
  98 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
  99 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 100 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 101 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 102 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 103   since 1.20)
 104 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 105   since 1.20)
 106 * Removed 'jquery.json' module. (deprecated since 1.24)
 107   Use the 'json' module and global JSON object instead.
 108 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 109   Also, the former will now throw an MWException if called with one or more
 110   arguments.
 111
 112 == Compatibility ==
 113
 114 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 115 HHVM 3.3.0.
 116
 117 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 118 support for them is somewhat less mature. There is experimental support for
 119 Oracle and Microsoft SQL Server.
 120
 121 The supported versions are:
 122
 123 * MySQL 5.0.2 or later
 124 * PostgreSQL 8.3 or later
 125 * SQLite 3.3.7 or later
 126 * Oracle 9.0.1 or later
 127 * Microsoft SQL Server 2005 (9.00.1399)
 128
 129 == Upgrading ==
 130
 131 1.25 has several database changes since 1.24, and will not work without schema
 132 updates. Note that due to changes to some very large tables like the revision
 133 table, the schema update may take quite long (minutes on a medium sized site,
 134 many hours on a large site).
 135
 136 If upgrading from before 1.11, and you are using a wiki as a commons
 137 repository, make sure that it is updated as well. Otherwise, errors may arise
 138 due to database schema changes.
 139
 140 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 141 new database fields are filled with data.
 142
 143 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 144 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 145 with MediaWiki 1.21.
 146
 147 Don't forget to always back up your database before upgrading!
 148
 149 See the file UPGRADE for more detailed upgrade instructions.
