RELEASE-NOTES-1.25

   1 Security reminder: If you have PHP's register_globals option set, you must
   2 turn it off. MediaWiki will not work with it enabled.

   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 * Upgrade jStorage to v0.4.12.
  25 * MediaWiki now natively supports page status indicators: icons (or short text
  26   snippets) usually displayed in the top-right corner of the page. They have
  27   been in use on Wikipedia for a long time, implemented using templates and CSS
  28   absolute positioning.
  29   - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
  30   - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
  31   - Adjusting custom skins to support indicators:
  32     https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
  33
  34 === Bug fixes in 1.25 ===
  35 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  36   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  37 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  38   10- and 13-digit forms) containing "X".
  39
  40 === Action API changes in 1.25 ===
  41 * (bug 65403) XML tag highlighting is now only performed for formats
  42   "xmlfm" and "wddxfm".
  43 * action=paraminfo supports generalized submodules (modules=query+value),
  44   querymodules and formatmodules are deprecated
  45 * action=paraminfo no longer outputs descriptions and other help text by
  46   default. If needed, it may be requested using the new 'helpformat' parameter.
  47 * action=help has been completely rewritten, and outputs help in HTML
  48   rather than plain text.
  49 * Hitting api.php without specifying an action now displays only the help for
  50   the main module, with links to submodule help.
  51 * API help is no longer displayed on errors.
  52 * Internationalized messages returned by the API will be in the wiki's content
  53   language by default. 'uselang' is now a recognized API parameter;
  54   "uselang=user" may be used to select the language from the current user's
  55   preferences.
  56 * Default output format for the API is now jsonfm.
  57 * Simplified continuation will return a "batchcomplete" property in the result
  58   when a batch of pages is complete.
  59 * Pretty-printed HTML output now has nicer formatting and (if available)
  60   better syntax highlighting.
  61
  62 === Action API internal changes in 1.25 ===
  63 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  64   Most existing modules should continue working without changes, but should do
  65   the following:
  66   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  67   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  68     to replace getParamDescription(). If necessary, the settings array returned
  69     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  70     message.
  71   * Implement getExamplesMessages() to replace getExamples().
  72 * Modules with submodules (like action=query) must have their submodules
  73   override ApiBase::getParent() to return the correct parent object.
  74 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  75   and will have no effect for modules using i18n messages. Use
  76   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  77 * Api formatters will no longer be asked to display the help screen on errors.
  78 * ApiMain::getCredits() was removed. The credits are available in the
  79   'api-credits' i18n message.
  80 * ApiFormatBase has been changed to support i18n and syntax highlighting via
  81   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
  82   has been removed.
  83 * ApiFormatBase now always buffers. Output is done when
  84   ApiFormatBase::closePrinter is called.
  85 * The following methods have been deprecated and may be removed in a future
  86   release:
  87   * ApiBase::getDescription
  88   * ApiBase::getParamDescription
  89   * ApiBase::getExamples
  90   * ApiBase::makeHelpMsg
  91   * ApiBase::makeHelpArrayToString
  92   * ApiBase::makeHelpMsgParameters
  93   * ApiFormatBase::setUnescapeAmps
  94   * ApiFormatBase::getWantsHelp
  95   * ApiFormatBase::setHelp
  96   * ApiFormatBase::formatHTML
  97   * ApiFormatBase::setBufferResult
  98   * ApiFormatBase::getDescription
  99   * ApiMain::setHelp
 100   * ApiMain::reallyMakeHelpMsg
 101   * ApiMain::makeHelpMsgHeader
 102   * ApiQueryImageInfo::getPropertyDescriptions
 103
 104 === Languages updated in 1.25 ===
 105
 106 MediaWiki supports over 350 languages. Many localisations are updated
 107 regularly. Below only new and removed languages are listed, as well as
 108 changes to languages because of Bugzilla reports.
 109
 110 === Other changes in 1.25 ===
 111 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 112   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 113   migration guide for creators and users of custom skins that relied on it.
 114 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 115 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 116   inline styles in the HTML.
 117 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 118 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 119 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 120 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 121 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 122 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 123   since 1.20)
 124 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 125   since 1.20)
 126 * Removed 'jquery.json' module. (deprecated since 1.24)
 127   Use the 'json' module and global JSON object instead.
 128 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 129   Also, the former will now throw an MWException if called with one or more
 130   arguments.
 131 * Removed hitcounters and associated code.
 132
 133 == Compatibility ==
 134
 135 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 136 HHVM 3.3.0.
 137
 138 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 139 support for them is somewhat less mature. There is experimental support for
 140 Oracle and Microsoft SQL Server.
 141
 142 The supported versions are:
 143
 144 * MySQL 5.0.2 or later
 145 * PostgreSQL 8.3 or later
 146 * SQLite 3.3.7 or later
 147 * Oracle 9.0.1 or later
 148 * Microsoft SQL Server 2005 (9.00.1399)
 149
 150 == Upgrading ==
 151
 152 1.25 has several database changes since 1.24, and will not work without schema
 153 updates. Note that due to changes to some very large tables like the revision
 154 table, the schema update may take quite long (minutes on a medium sized site,
 155 many hours on a large site).
 156
 157 If upgrading from before 1.11, and you are using a wiki as a commons
 158 repository, make sure that it is updated as well. Otherwise, errors may arise
 159 due to database schema changes.
 160
 161 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 162 new database fields are filled with data.
 163
 164 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 165 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 166 with MediaWiki 1.21.
 167
 168 Don't forget to always back up your database before upgrading!
 169
 170 See the file UPGRADE for more detailed upgrade instructions.
