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 ===

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.
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".
31 === Action API changes in 1.25 ===
32 * (bug 65403) XML tag highlighting is now only performed for formats
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
48 === Action API internal changes in 1.25 ===
49 * ApiHelp has been rewritten to support i18n and paginated HTML output.
50 Most existing modules should continue working without changes, but should do
52 * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
53 * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
54 to replace getParamDescription(). If necessary, the settings array returned
55 by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
57 * Implement getExamplesMessages() to replace getExamples().
58 * Modules with submodules (like action=query) must have their submodules
59 override ApiBase::getParent() to return the correct parent object.
60 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
61 and will have no effect for modules using i18n messages. Use
62 'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
63 * Api formatters will no longer be asked to display the help screen on errors.

85 changes to languages because of Bugzilla reports.
87 === Other changes in 1.25 ===
88 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been

111 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
114 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
115 support for them is somewhat less mature. There is experimental support for
116 Oracle and Microsoft SQL Server.
118 The supported versions are:
120 * MySQL 5.0.2 or later
121 * PostgreSQL 8.3 or later
122 * SQLite 3.3.7 or later
123 * Oracle 9.0.1 or later
124 * Microsoft SQL Server 2005 (9.00.1399)
128 1.25 has several database changes since 1.24, and will not work without schema
129 updates. Note that due to changes to some very large tables like the revision
130 table, the schema update may take quite long (minutes on a medium sized site,
131 many hours on a large site).
133 If upgrading from before 1.11, and you are using a wiki as a commons
134 repository, make sure that it is updated as well. Otherwise, errors may arise
135 due to database schema changes.
137 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
138 new database fields are filled with data.
140 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
141 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
144 Don't forget to always back up your database before upgrading!
146 See the file UPGRADE for more detailed upgrade instructions.
