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