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.
19 * (bug 72951) The UserGetLanguageObject hook may be passed any IContextSource
20 for its $context parameter. Formerly it was documented as receiving a
21 RequestContext specifically.
22 * Profiling was restructured and $wgProfiler now requires an 'output' parameter.
23 See StartProfiler.sample for details.
24 * $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
25 might be a flash policy directive configurable.
27 === New features in 1.25 ===
28 * (bug 62861) Updated plural rules to CLDR 26. Includes incompatible changes
29 for plural forms in Russian, Prussian, Tagalog, Manx and several languages
30 that fall back to Russian.
31 * (bug 58139) ResourceLoaderFileModule now supports language fallback
32 for 'languageScripts'.
33 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
34 parser output for a content object before links update.
35 * (bug 35785) Enhanced recent changes and extended watchlist are now default.
36 Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
37 and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
38 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
39 in CSS. This results in slight size increase before gzip compression (due to
40 percent-encoding), but up to 20% decrease after it.
41 * Upgrade jStorage to v0.4.12.
42 * MediaWiki now natively supports page status indicators: icons (or short text
43 snippets) usually displayed in the top-right corner of the page. They have
44 been in use on Wikipedia for a long time, implemented using templates and CSS
46 - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
47 - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
48 - Adjusting custom skins to support indicators:
49 https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
50 * Edit tokens may now be time-limited: passing a maximum age to
51 User::matchEditToken will reject any older tokens.
52 * The debug logging internals have been overhauled, and are now using the
55 === Bug fixes in 1.25 ===
56 * (bug 71003) No additional code will be generated to try to load CSS-embedded
57 SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
58 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
59 10- and 13-digit forms) containing "X".
60 * Page moving was refactored into a MovePage class. As part of that:
61 ** The AbortMove hook was removed.
62 ** MovePageIsValidMove is for extensions to specify whether a page
63 cannot be moved for technical reasons, and should not be overriden.
64 ** MovePageCheckPermissions is for checking whether the given user is
65 allowed to make the move.
66 ** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
67 ** Title::moveTo() was deprecated. Use the MovePage class instead.
68 ** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
69 and MovePage::checkPermissions().
71 === Action API changes in 1.25 ===
72 * (bug 65403) XML tag highlighting is now only performed for formats
74 * action=paraminfo supports generalized submodules (modules=query+value),
75 querymodules and formatmodules are deprecated
76 * action=paraminfo no longer outputs descriptions and other help text by
77 default. If needed, it may be requested using the new 'helpformat' parameter.
78 * action=help has been completely rewritten, and outputs help in HTML
79 rather than plain text.
80 * Hitting api.php without specifying an action now displays only the help for
81 the main module, with links to submodule help.
82 * API help is no longer displayed on errors.
83 * 'uselang' is now a recognized API parameter; "uselang=user" may be used to
84 explicitly select the language from the current user's preferences, and
85 "uselang=content" may be used to select the wiki's content language.
86 * Default output format for the API is now jsonfm.
87 * Simplified continuation will return a "batchcomplete" property in the result
88 when a batch of pages is complete.
89 * Pretty-printed HTML output now has nicer formatting and (if available)
90 better syntax highlighting.
91 * Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
92 list=alldeletedrevisions.
93 * prop=revisions will gracefully continue when given too many revids or titles,
94 rather than just ignoring the extras.
95 * prop=revisions will no longer die if rvcontentformat doesn't match a
96 revision's content model; it will instead warn and omit the content.
97 * If the user has the 'deletedhistory' right, action=query's revids parameter
98 will now recognize deleted revids.
99 * prop=revisions may be used as a generator, generating revids.
101 === Action API internal changes in 1.25 ===
102 * ApiHelp has been rewritten to support i18n and paginated HTML output.
103 Most existing modules should continue working without changes, but should do
105 * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
106 * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
107 to replace getParamDescription(). If necessary, the settings array returned
108 by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
110 * Implement getExamplesMessages() to replace getExamples().
111 * Modules with submodules (like action=query) must have their submodules
112 override ApiBase::getParent() to return the correct parent object.
113 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
114 and will have no effect for modules using i18n messages. Use
115 'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
116 * Api formatters will no longer be asked to display the help screen on errors.
117 * ApiMain::getCredits() was removed. The credits are available in the
118 'api-credits' i18n message.
119 * ApiFormatBase has been changed to support i18n and syntax highlighting via
120 extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
122 * ApiFormatBase now always buffers. Output is done when
123 ApiFormatBase::closePrinter is called.
124 * Much of the logic in ApiQueryRevisions has been split into ApiQueryRevisionsBase.
125 * The 'revids' parameter supplied by ApiPageSet will now count deleted
126 revisions as "good" if the user has the 'deletedhistory' right. New methods
127 ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
128 provided to access just the live or just the deleted revids.
129 * The following methods have been deprecated and may be removed in a future
131 * ApiBase::getDescription
132 * ApiBase::getParamDescription
133 * ApiBase::getExamples
134 * ApiBase::makeHelpMsg
135 * ApiBase::makeHelpArrayToString
136 * ApiBase::makeHelpMsgParameters
137 * ApiFormatBase::setUnescapeAmps
138 * ApiFormatBase::getWantsHelp
139 * ApiFormatBase::setHelp
140 * ApiFormatBase::formatHTML
141 * ApiFormatBase::setBufferResult
142 * ApiFormatBase::getDescription
144 * ApiMain::reallyMakeHelpMsg
145 * ApiMain::makeHelpMsgHeader
146 * ApiQueryImageInfo::getPropertyDescriptions
147 * The following classes have been deprecated and may be removed in a future
149 * ApiQueryDeletedrevs
151 === Languages updated in 1.25 ===
153 MediaWiki supports over 350 languages. Many localisations are updated
154 regularly. Below only new and removed languages are listed, as well as
155 changes to languages because of Bugzilla reports.
157 * (bug 64440) Kazakh (kk) wikis should no longer forcefully reset the user's
158 interface language to kk where unexpected.
160 === Other changes in 1.25 ===
161 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
162 removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
163 migration guide for creators and users of custom skins that relied on it.
164 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
165 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
166 inline styles in the HTML.
167 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)

176 * Removed 'jquery.json' module. (deprecated since 1.24)
177 Use the 'json' module and global JSON object instead.
178 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
179 Also, the former will now throw an MWException if called with one or more
181 * Removed hitcounters and associated code.
182 * The "temp" zone of the upload respository is now considered private. If it
183 already exists (such as under the images/ directory), please make sure that
184 the directory is not web readable (e.g. via a .htaccess file).
185 * BREAKING CHANGE: In the XML dump format used by Special:Export and
186 dumpBackup.php, the <model> and <format> tags now apprear before the <text>
187 tag, instead of after the <text> and <sha1> tags.
188 The new schema version is 0.10, the new schema URI is
189 <https://www.mediawiki.org/xml/export-0.10.xsd>.
190 * MWFunction::call() and MWFunction::callArray() were removed, having being
192 * Deprecated the getInternalLinkAttributes, getInternalLinkAttributesObj,
193 and getInternalLinkAttributes methods in Linker, and removed
194 getExternalLinkAttributes method, which was deprecated in MediaWiki 1.18.
198 MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
201 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
202 support for them is somewhat less mature. There is experimental support for
203 Oracle and Microsoft SQL Server.
205 The supported versions are:
207 * MySQL 5.0.2 or later
208 * PostgreSQL 8.3 or later
209 * SQLite 3.3.7 or later
210 * Oracle 9.0.1 or later
211 * Microsoft SQL Server 2005 (9.00.1399)
215 1.25 has several database changes since 1.24, and will not work without schema
216 updates. Note that due to changes to some very large tables like the revision
217 table, the schema update may take quite long (minutes on a medium sized site,
218 many hours on a large site).
220 If upgrading from before 1.11, and you are using a wiki as a commons
221 repository, make sure that it is updated as well. Otherwise, errors may arise
222 due to database schema changes.
224 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
225 new database fields are filled with data.
227 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
228 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
231 Don't forget to always back up your database before upgrading!
233 See the file UPGRADE for more detailed upgrade instructions.
