6 THIS IS NOT A RELEASE YET
8 MediaWiki 1.25 is an alpha-quality branch and is not recommended for use in
11 === Configuration changes in 1.25 ===
12 * $wgPageShowWatchingUsers was removed.
13 * $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
14 * $wgAntiLockFlags was removed.
15 * Edit tokens returned from User::getEditToken may change on every call. Token
16 validity must be checked by passing the user-supplied token to
17 User::matchEditToken rather than by testing for equality with a
18 newly-generated token.
20 === New features in 1.25 ===
21 * (bug 62861) Updated plural rules to CLDR 26. Includes incompatible changes
22 for plural forms in Russian, Prussian, Tagalog, Manx and several languages
23 that fall back to Russian.
24 * (bug 58139) ResourceLoaderFileModule now supports language fallback
25 for 'languageScripts'.
26 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
27 parser output for a content object before links update.
28 * (bug 35785) Enhanced recent changes and extended watchlist are now default.
29 Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
30 and https://www.mediawiki.org/wiki/Manual:$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
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 * The debug logging internals have been overhauled, and are now using the
48 === Bug fixes in 1.25 ===
49 * (bug 71003) No additional code will be generated to try to load CSS-embedded
50 SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
51 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
52 10- and 13-digit forms) containing "X".
53 * Page moving was refactored into a MovePage class. As part of that:
54 ** The AbortMove hook was removed.
55 ** MovePageIsValidMove is for extensions to specify whether a page
56 cannot be moved for technical reasons, and should not be overriden.
57 ** MovePageCheckPermissions is for checking whether the given user is
58 allowed to make the move.
59 ** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
60 ** Title::moveTo() was deprecated. Use the MovePage class instead.
61 ** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
62 and MovePage::checkPermissions().
64 === Action API changes in 1.25 ===
65 * (bug 65403) XML tag highlighting is now only performed for formats
67 * action=paraminfo supports generalized submodules (modules=query+value),
68 querymodules and formatmodules are deprecated
69 * action=paraminfo no longer outputs descriptions and other help text by
70 default. If needed, it may be requested using the new 'helpformat' parameter.
71 * action=help has been completely rewritten, and outputs help in HTML
72 rather than plain text.
73 * Hitting api.php without specifying an action now displays only the help for
74 the main module, with links to submodule help.
75 * API help is no longer displayed on errors.
76 * Internationalized messages returned by the API will be in the wiki's content
77 language by default. 'uselang' is now a recognized API parameter;
78 "uselang=user" may be used to select the language from the current user's
80 * Default output format for the API is now jsonfm.
81 * Simplified continuation will return a "batchcomplete" property in the result
82 when a batch of pages is complete.
83 * Pretty-printed HTML output now has nicer formatting and (if available)
84 better syntax highlighting.
86 === Action API internal changes in 1.25 ===
87 * ApiHelp has been rewritten to support i18n and paginated HTML output.
88 Most existing modules should continue working without changes, but should do
90 * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
91 * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
92 to replace getParamDescription(). If necessary, the settings array returned
93 by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
95 * Implement getExamplesMessages() to replace getExamples().
96 * Modules with submodules (like action=query) must have their submodules
97 override ApiBase::getParent() to return the correct parent object.
98 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
99 and will have no effect for modules using i18n messages. Use
100 'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
101 * Api formatters will no longer be asked to display the help screen on errors.
102 * ApiMain::getCredits() was removed. The credits are available in the
103 'api-credits' i18n message.
104 * ApiFormatBase has been changed to support i18n and syntax highlighting via
105 extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
107 * ApiFormatBase now always buffers. Output is done when
108 ApiFormatBase::closePrinter is called.
109 * The following methods have been deprecated and may be removed in a future
111 * ApiBase::getDescription
112 * ApiBase::getParamDescription
113 * ApiBase::getExamples
114 * ApiBase::makeHelpMsg
115 * ApiBase::makeHelpArrayToString
116 * ApiBase::makeHelpMsgParameters
117 * ApiFormatBase::setUnescapeAmps
118 * ApiFormatBase::getWantsHelp
119 * ApiFormatBase::setHelp
120 * ApiFormatBase::formatHTML
121 * ApiFormatBase::setBufferResult

124 * ApiMain::reallyMakeHelpMsg
125 * ApiMain::makeHelpMsgHeader
126 * ApiQueryImageInfo::getPropertyDescriptions
128 === Languages updated in 1.25 ===
130 MediaWiki supports over 350 languages. Many localisations are updated
131 regularly. Below only new and removed languages are listed, as well as
132 changes to languages because of Bugzilla reports.
134 === Other changes in 1.25 ===
135 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
136 removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
137 migration guide for creators and users of custom skins that relied on it.
138 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
139 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
140 inline styles in the HTML.
141 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
142 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
143 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
144 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
145 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
146 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
148 * Removed 'async' parameter from the mw.Api#getCategories() method. (deprecated
150 * Removed 'jquery.json' module. (deprecated since 1.24)
151 Use the 'json' module and global JSON object instead.

153 Also, the former will now throw an MWException if called with one or more
155 * Removed hitcounters and associated code.
156 * The "temp" zone of the upload respository is now considered private. If it
157 already exists (such as under the images/ directory), please make sure that
158 the directory is not web readable (e.g. via a .htaccess file).
162 MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
165 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
166 support for them is somewhat less mature. There is experimental support for
167 Oracle and Microsoft SQL Server.
169 The supported versions are:
171 * MySQL 5.0.2 or later
172 * PostgreSQL 8.3 or later
173 * SQLite 3.3.7 or later
174 * Oracle 9.0.1 or later
175 * Microsoft SQL Server 2005 (9.00.1399)
179 1.25 has several database changes since 1.24, and will not work without schema
180 updates. Note that due to changes to some very large tables like the revision
181 table, the schema update may take quite long (minutes on a medium sized site,
182 many hours on a large site).
184 If upgrading from before 1.11, and you are using a wiki as a commons
185 repository, make sure that it is updated as well. Otherwise, errors may arise
186 due to database schema changes.
188 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
189 new database fields are filled with data.
191 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
192 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
195 Don't forget to always back up your database before upgrading!
197 See the file UPGRADE for more detailed upgrade instructions.
