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
  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 * Pretty-printed HTML output now has nicer formatting and (if available)
  51   better syntax highlighting.
  52
  53 === Action API internal changes in 1.25 ===
  54 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  55   Most existing modules should continue working without changes, but should do
  56   the following:
  57   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  58   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  59     to replace getParamDescription(). If necessary, the settings array returned
  60     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  61     message.
  62   * Implement getExamplesMessages() to replace getExamples().
  63 * Modules with submodules (like action=query) must have their submodules
  64   override ApiBase::getParent() to return the correct parent object.
  65 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  66   and will have no effect for modules using i18n messages. Use
  67   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  68 * Api formatters will no longer be asked to display the help screen on errors.
  69 * ApiMain::getCredits() was removed. The credits are available in the
  70   'api-credits' i18n message.
  71 * ApiFormatBase has been changed to support i18n and syntax highlighting via
  72   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
  73   has been removed.
  74 * ApiFormatBase now always buffers. Output is done when
  75   ApiFormatBase::closePrinter is called.
  76 * The following methods have been deprecated and may be removed in a future
  77   release:
  78   * ApiBase::getDescription
  79   * ApiBase::getParamDescription
  80   * ApiBase::getExamples
  81   * ApiBase::makeHelpMsg
  82   * ApiBase::makeHelpArrayToString
  83   * ApiBase::makeHelpMsgParameters
  84   * ApiFormatBase::setUnescapeAmps
  85   * ApiFormatBase::getWantsHelp
  86   * ApiFormatBase::setHelp
  87   * ApiFormatBase::formatHTML
  88   * ApiFormatBase::setBufferResult
  89   * ApiFormatBase::getDescription
  90   * ApiMain::setHelp
  91   * ApiMain::reallyMakeHelpMsg
  92   * ApiMain::makeHelpMsgHeader
  93
  94 === Languages updated in 1.25 ===
  95
  96 MediaWiki supports over 350 languages. Many localisations are updated
  97 regularly. Below only new and removed languages are listed, as well as
  98 changes to languages because of Bugzilla reports.
  99
 100 === Other changes in 1.25 ===
 101 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 102   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 103   migration guide for creators and users of custom skins that relied on it.
 104 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 105 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 106   inline styles in the HTML.
 107 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 108 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 109 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 110 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 111 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 112 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 113   since 1.20)
 114 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 115   since 1.20)
 116 * Removed 'jquery.json' module. (deprecated since 1.24)
 117   Use the 'json' module and global JSON object instead.
 118 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 119   Also, the former will now throw an MWException if called with one or more
 120   arguments.
 121
 122 == Compatibility ==
 123
 124 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 125 HHVM 3.3.0.
 126
 127 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 128 support for them is somewhat less mature. There is experimental support for
 129 Oracle and Microsoft SQL Server.
 130
 131 The supported versions are:
 132
 133 * MySQL 5.0.2 or later
 134 * PostgreSQL 8.3 or later
 135 * SQLite 3.3.7 or later
 136 * Oracle 9.0.1 or later
 137 * Microsoft SQL Server 2005 (9.00.1399)
 138
 139 == Upgrading ==
 140
 141 1.25 has several database changes since 1.24, and will not work without schema
 142 updates. Note that due to changes to some very large tables like the revision
 143 table, the schema update may take quite long (minutes on a medium sized site,
 144 many hours on a large site).
 145
 146 If upgrading from before 1.11, and you are using a wiki as a commons
 147 repository, make sure that it is updated as well. Otherwise, errors may arise
 148 due to database schema changes.
 149
 150 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 151 new database fields are filled with data.
 152
 153 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 154 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 155 with MediaWiki 1.21.
 156
 157 Don't forget to always back up your database before upgrading!
 158
 159 See the file UPGRADE for more detailed upgrade instructions.

 163 == Online documentation ==
 164

 170
 171 == Mailing list ==
 172
 173 A mailing list is available for MediaWiki user support and discussion:
 174
 175         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 176
 177 A low-traffic announcements-only list is also available:
 178
 179         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 180
 181 It's highly recommended that you sign up for one of these lists if you're
 182 going to run a public MediaWiki, so you can be notified of security fixes.
