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.

   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 * $wgAntiLockFlags was removed.
  15 * Edit tokens returned from User::getEditToken may change on every call. Token
  16   validity must be checked by passing the user-supplied token to
  17   User::matchEditToken rather than by testing for equality with a
  18   newly-generated token.
  19
  20 === New features in 1.25 ===
  21 * (bug 62861) Updated plural rules to CLDR 26. Includes incompatible changes
  22   for plural forms in Russian, Prussian, Tagalog, Manx and several languages
  23   that fall back to Russian.
  24 * (bug 58139) ResourceLoaderFileModule now supports language fallback
  25   for 'languageScripts'.
  26 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
  27   parser output for a content object before links update.
  28 * (bug 35785) Enhanced recent changes and extended watchlist are now default.
  29   Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
  30   and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
  31 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
  32   in CSS. This results in slight size increase before gzip compression (due to
  33   percent-encoding), but up to 20% decrease after it.
  34 * Upgrade jStorage to v0.4.12.
  35 * MediaWiki now natively supports page status indicators: icons (or short text
  36   snippets) usually displayed in the top-right corner of the page. They have
  37   been in use on Wikipedia for a long time, implemented using templates and CSS
  38   absolute positioning.
  39   - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
  40   - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
  41   - Adjusting custom skins to support indicators:
  42     https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
  43 * Edit tokens may now be time-limited: passing a maximum age to
  44   User::matchEditToken will reject any older tokens.
  45
  46 === Bug fixes in 1.25 ===
  47 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  48   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  49 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  50   10- and 13-digit forms) containing "X".
  51 * Page moving was refactored into a MovePage class. As part of that:
  52 ** The AbortMove hook was removed.
  53 ** MovePageIsValidMove is for extensions to specify whether a page
  54    cannot be moved for technical reasons, and should not be overriden.
  55 ** MovePageCheckPermissions is for checking whether the given user is
  56    allowed to make the move.
  57 ** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
  58 ** Title::moveTo() was deprecated. Use the MovePage class instead.
  59 ** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
  60    and MovePage::checkPermissions().
  61
  62 === Action API changes in 1.25 ===
  63 * (bug 65403) XML tag highlighting is now only performed for formats
  64   "xmlfm" and "wddxfm".
  65 * action=paraminfo supports generalized submodules (modules=query+value),
  66   querymodules and formatmodules are deprecated
  67 * action=paraminfo no longer outputs descriptions and other help text by
  68   default. If needed, it may be requested using the new 'helpformat' parameter.
  69 * action=help has been completely rewritten, and outputs help in HTML
  70   rather than plain text.
  71 * Hitting api.php without specifying an action now displays only the help for
  72   the main module, with links to submodule help.
  73 * API help is no longer displayed on errors.
  74 * Internationalized messages returned by the API will be in the wiki's content
  75   language by default. 'uselang' is now a recognized API parameter;
  76   "uselang=user" may be used to select the language from the current user's
  77   preferences.
  78 * Default output format for the API is now jsonfm.
  79 * Simplified continuation will return a "batchcomplete" property in the result
  80   when a batch of pages is complete.
  81 * Pretty-printed HTML output now has nicer formatting and (if available)
  82   better syntax highlighting.
  83
  84 === Action API internal changes in 1.25 ===
  85 * ApiHelp has been rewritten to support i18n and paginated HTML output.
  86   Most existing modules should continue working without changes, but should do
  87   the following:
  88   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
  89   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
  90     to replace getParamDescription(). If necessary, the settings array returned
  91     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
  92     message.
  93   * Implement getExamplesMessages() to replace getExamples().
  94 * Modules with submodules (like action=query) must have their submodules
  95   override ApiBase::getParent() to return the correct parent object.
  96 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
  97   and will have no effect for modules using i18n messages. Use
  98   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
  99 * Api formatters will no longer be asked to display the help screen on errors.
 100 * ApiMain::getCredits() was removed. The credits are available in the
 101   'api-credits' i18n message.
 102 * ApiFormatBase has been changed to support i18n and syntax highlighting via
 103   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
 104   has been removed.
 105 * ApiFormatBase now always buffers. Output is done when
 106   ApiFormatBase::closePrinter is called.
 107 * The following methods have been deprecated and may be removed in a future
 108   release:
 109   * ApiBase::getDescription
 110   * ApiBase::getParamDescription
 111   * ApiBase::getExamples
 112   * ApiBase::makeHelpMsg
 113   * ApiBase::makeHelpArrayToString
 114   * ApiBase::makeHelpMsgParameters
 115   * ApiFormatBase::setUnescapeAmps
 116   * ApiFormatBase::getWantsHelp
 117   * ApiFormatBase::setHelp
 118   * ApiFormatBase::formatHTML
 119   * ApiFormatBase::setBufferResult
 120   * ApiFormatBase::getDescription
 121   * ApiMain::setHelp
 122   * ApiMain::reallyMakeHelpMsg
 123   * ApiMain::makeHelpMsgHeader
 124   * ApiQueryImageInfo::getPropertyDescriptions
 125
 126 === Languages updated in 1.25 ===
 127
 128 MediaWiki supports over 350 languages. Many localisations are updated
 129 regularly. Below only new and removed languages are listed, as well as
 130 changes to languages because of Bugzilla reports.
 131
 132 === Other changes in 1.25 ===
 133 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 134   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 135   migration guide for creators and users of custom skins that relied on it.
 136 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
 137 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
 138   inline styles in the HTML.
 139 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 140 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 141 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 142 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 143 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 144 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 145   since 1.20)
 146 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 147   since 1.20)
 148 * Removed 'jquery.json' module. (deprecated since 1.24)
 149   Use the 'json' module and global JSON object instead.
 150 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 151   Also, the former will now throw an MWException if called with one or more
 152   arguments.
 153 * Removed hitcounters and associated code.
 154 * The "temp" zone of the upload respository is now considered private. If it
 155   already exists (such as under the images/ directory), please make sure that
 156   the directory is not web readable (e.g. via a .htaccess file).
 157
 158 == Compatibility ==
 159
 160 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
 161 HHVM 3.3.0.
 162
 163 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 164 support for them is somewhat less mature. There is experimental support for
 165 Oracle and Microsoft SQL Server.
 166
 167 The supported versions are:
 168
 169 * MySQL 5.0.2 or later
 170 * PostgreSQL 8.3 or later
 171 * SQLite 3.3.7 or later
 172 * Oracle 9.0.1 or later
 173 * Microsoft SQL Server 2005 (9.00.1399)
 174
 175 == Upgrading ==
 176
 177 1.25 has several database changes since 1.24, and will not work without schema
 178 updates. Note that due to changes to some very large tables like the revision
 179 table, the schema update may take quite long (minutes on a medium sized site,
 180 many hours on a large site).
 181
 182 If upgrading from before 1.11, and you are using a wiki as a commons
 183 repository, make sure that it is updated as well. Otherwise, errors may arise
 184 due to database schema changes.
 185
 186 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 187 new database fields are filled with data.
 188
 189 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 190 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 191 with MediaWiki 1.21.
 192
 193 Don't forget to always back up your database before upgrading!
 194
 195 See the file UPGRADE for more detailed upgrade instructions.
