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

116 changes to languages because of Bugzilla reports.
118 === Other changes in 1.25 ===
119 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
120 removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
121 migration guide for creators and users of custom skins that relied on it.
122 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
123 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
124 inline styles in the HTML.

134 * Removed 'jquery.json' module. (deprecated since 1.24)
135 Use the 'json' module and global JSON object instead.

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