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.
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 * $wgAntiLockFlags was removed.
16 === New features in 1.25 ===
17 * (bug 58139) ResourceLoaderFileModule now supports language fallback
18 for 'languageScripts'.
19 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
20 parser output for a content object before links update.
21 * (bug 35785) Enhanced recent changes and extended watchlist are now default.
22 Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
23 and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
24 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
25 in CSS. This results in slight size increase before gzip compression (due to
26 percent-encoding), but up to 20% decrease after it.
27 * Upgrade jStorage to v0.4.12.
28 * MediaWiki now natively supports page status indicators: icons (or short text
29 snippets) usually displayed in the top-right corner of the page. They have
30 been in use on Wikipedia for a long time, implemented using templates and CSS
32 - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
33 - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
34 - Adjusting custom skins to support indicators:
35 https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
37 === Bug fixes in 1.25 ===
38 * (bug 71003) No additional code will be generated to try to load CSS-embedded
39 SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
40 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
41 10- and 13-digit forms) containing "X".
43 === Action API changes in 1.25 ===
44 * (bug 65403) XML tag highlighting is now only performed for formats
46 * action=paraminfo supports generalized submodules (modules=query+value),
47 querymodules and formatmodules are deprecated
48 * action=paraminfo no longer outputs descriptions and other help text by
49 default. If needed, it may be requested using the new 'helpformat' parameter.
50 * action=help has been completely rewritten, and outputs help in HTML
51 rather than plain text.
52 * Hitting api.php without specifying an action now displays only the help for
53 the main module, with links to submodule help.
54 * API help is no longer displayed on errors.
55 * Internationalized messages returned by the API will be in the wiki's content
56 language by default. 'uselang' is now a recognized API parameter;
57 "uselang=user" may be used to select the language from the current user's
59 * Default output format for the API is now jsonfm.
60 * Simplified continuation will return a "batchcomplete" property in the result
61 when a batch of pages is complete.
62 * Pretty-printed HTML output now has nicer formatting and (if available)
63 better syntax highlighting.
65 === Action API internal changes in 1.25 ===
66 * ApiHelp has been rewritten to support i18n and paginated HTML output.
67 Most existing modules should continue working without changes, but should do
69 * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
70 * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
71 to replace getParamDescription(). If necessary, the settings array returned
72 by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
74 * Implement getExamplesMessages() to replace getExamples().
75 * Modules with submodules (like action=query) must have their submodules
76 override ApiBase::getParent() to return the correct parent object.
77 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
78 and will have no effect for modules using i18n messages. Use
79 'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
80 * Api formatters will no longer be asked to display the help screen on errors.
81 * ApiMain::getCredits() was removed. The credits are available in the
82 'api-credits' i18n message.
83 * ApiFormatBase has been changed to support i18n and syntax highlighting via
84 extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
86 * ApiFormatBase now always buffers. Output is done when
87 ApiFormatBase::closePrinter is called.
88 * The following methods have been deprecated and may be removed in a future
90 * ApiBase::getDescription
91 * ApiBase::getParamDescription
92 * ApiBase::getExamples
93 * ApiBase::makeHelpMsg
94 * ApiBase::makeHelpArrayToString
95 * ApiBase::makeHelpMsgParameters
96 * ApiFormatBase::setUnescapeAmps

101 * ApiFormatBase::getDescription
103 * ApiMain::reallyMakeHelpMsg
104 * ApiMain::makeHelpMsgHeader

110 changes to languages because of Bugzilla reports.
112 === Other changes in 1.25 ===
113 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been

115 migration guide for creators and users of custom skins that relied on it.
116 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.

137 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
140 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
141 support for them is somewhat less mature. There is experimental support for
142 Oracle and Microsoft SQL Server.
144 The supported versions are:
146 * MySQL 5.0.2 or later
147 * PostgreSQL 8.3 or later
148 * SQLite 3.3.7 or later
149 * Oracle 9.0.1 or later
150 * Microsoft SQL Server 2005 (9.00.1399)
154 1.25 has several database changes since 1.24, and will not work without schema
155 updates. Note that due to changes to some very large tables like the revision
156 table, the schema update may take quite long (minutes on a medium sized site,
157 many hours on a large site).
159 If upgrading from before 1.11, and you are using a wiki as a commons
160 repository, make sure that it is updated as well. Otherwise, errors may arise
161 due to database schema changes.
163 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
164 new database fields are filled with data.
166 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
167 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
170 Don't forget to always back up your database before upgrading!
172 See the file UPGRADE for more detailed upgrade instructions.
174 For notes on 1.23.x and older releases, see HISTORY.
