   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 * MediaWiki now natively supports page status indicators: icons (or short text
  29   snippets) usually displayed in the top-right corner of the page. They have
  30   been in use on Wikipedia for a long time, implemented using templates and CSS
  31   absolute positioning.
  32   - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
  33   - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
  34   - Adjusting custom skins to support indicators:
  35     https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
  36
  37 === Bug fixes in 1.25 ===
  38 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  39   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  40 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  41   10- and 13-digit forms) containing "X".
  42
  43 === Action API changes in 1.25 ===
  44 * (bug 65403) XML tag highlighting is now only performed for formats
  45   "xmlfm" and "wddxfm".
  46 * action=paraminfo supports generalized submodules (modules=query+value),
  47   querymodules and formatmodules are deprecated
  48 * action=paraminfo no longer outputs descriptions and other help text by
  49   default. If needed, it may be requested using the new 'helpformat' parameter.
  50 * action=help has been completely rewritten, and outputs help in HTML
  51   rather than plain text.
  52 * Hitting api.php without specifying an action now displays only the help for
  53   the main module, with links to submodule help.
  54 * API help is no longer displayed on errors.
  55 * Internationalized messages returned by the API will be in the wiki's content
  56   language by default. 'uselang' is now a recognized API parameter;
  57   "uselang=user" may be used to select the language from the current user's
  58   preferences.
  59 * Default output format for the API is now jsonfm.
  60 * Simplified continuation will return a "batchcomplete" property in the result
  61   when a batch of pages is complete.
  62 * Pretty-printed HTML output now has nicer formatting and (if available)
  63   better syntax highlighting.
  64
  65 === Action API internal changes in 1.25 ===
  66 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  67   Most existing modules should continue working without changes, but should do
  68   the following:
  69   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  70   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  71     to replace getParamDescription(). If necessary, the settings array returned
  72     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  73     message.
  74   * Implement getExamplesMessages() to replace getExamples().
  75 * Modules with submodules (like action=query) must have their submodules
  76   override ApiBase::getParent() to return the correct parent object.
  77 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  78   and will have no effect for modules using i18n messages. Use
  79   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  80 * Api formatters will no longer be asked to display the help screen on errors.
  81 * ApiMain::getCredits() was removed. The credits are available in the
  82   'api-credits' i18n message.
  83 * ApiFormatBase has been changed to support i18n and syntax highlighting via
  84   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
  85   has been removed.
  86 * ApiFormatBase now always buffers. Output is done when
  87   ApiFormatBase::closePrinter is called.
  88 * The following methods have been deprecated and may be removed in a future
  89   release:
  90   * ApiBase::getDescription
  91   * ApiBase::getParamDescription
  92   * ApiBase::getExamples
  93   * ApiBase::makeHelpMsg
  94   * ApiBase::makeHelpArrayToString
  95   * ApiBase::makeHelpMsgParameters
  96   * ApiFormatBase::setUnescapeAmps
  97   * ApiFormatBase::getWantsHelp
  98   * ApiFormatBase::setHelp
  99   * ApiFormatBase::formatHTML
 100   * ApiFormatBase::setBufferResult
 101   * ApiFormatBase::getDescription
 102   * ApiMain::setHelp
 103   * ApiMain::reallyMakeHelpMsg
 104   * ApiMain::makeHelpMsgHeader
 105   * ApiQueryImageInfo::getPropertyDescriptions
 106
 107 === Languages updated in 1.25 ===
 108
 109 MediaWiki supports over 350 languages. Many localisations are updated
 110 regularly. Below only new and removed languages are listed, as well as
 111 changes to languages because of Bugzilla reports.
 112
 113 === Other changes in 1.25 ===
 114 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 115   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 116   migration guide for creators and users of custom skins that relied on it.
 117 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 118 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 119   inline styles in the HTML.
 120 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 121 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 122 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 123 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 124 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 125 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 126   since 1.20)
 127 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 128   since 1.20)
 129 * Removed 'jquery.json' module. (deprecated since 1.24)
 130   Use the 'json' module and global JSON object instead.
 131 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 132   Also, the former will now throw an MWException if called with one or more
 133   arguments.
 134 * Removed hitcounters and associated code.
 135
 136 == Compatibility ==
 137
 138 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 139 HHVM 3.3.0.
 140
 141 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 142 support for them is somewhat less mature. There is experimental support for
 143 Oracle and Microsoft SQL Server.
 144
 145 The supported versions are:
 146
 147 * MySQL 5.0.2 or later
 148 * PostgreSQL 8.3 or later
 149 * SQLite 3.3.7 or later
 150 * Oracle 9.0.1 or later
 151 * Microsoft SQL Server 2005 (9.00.1399)
 152
 153 == Upgrading ==
 154
 155 1.25 has several database changes since 1.24, and will not work without schema
 156 updates. Note that due to changes to some very large tables like the revision
 157 table, the schema update may take quite long (minutes on a medium sized site,
 158 many hours on a large site).
 159
 160 If upgrading from before 1.11, and you are using a wiki as a commons
 161 repository, make sure that it is updated as well. Otherwise, errors may arise
 162 due to database schema changes.
 163
 164 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 165 new database fields are filled with data.
 166
 167 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 168 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 169 with MediaWiki 1.21.
 170
 171 Don't forget to always back up your database before upgrading!
 172
 173 See the file UPGRADE for more detailed upgrade instructions.
