1 Security reminder: MediaWiki does not require PHP's register_globals. If you
2 have it on, turn it '''off''' if you can.
6 THIS IS NOT A RELEASE YET
8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
11 === Configuration changes in 1.24 ===
12 * The server's canonical hostname is available as $wgServerName, which is
13 exposed in both mw.config and ApiQuerySiteInfo.
14 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
15 for using the old schema of the page_props table, in case the respective
16 schema update was not applied.
17 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
18 user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
19 if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
20 * $wgMasterWaitTimeout has been deprecated.
21 * $wgDBClusterTimeout has been removed.
22 * $wgProxyKey has been removed. It is no longer used by MediaWiki core.
23 Ensure $wgSecretKey is set in LocalSettings.php.
24 * $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
25 contains an array of interwiki prefixes that should be treated as language
26 prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
29 === New features in 1.24 ===
30 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
31 WhatLinksHere entries.
32 * Added a new hook, "ContentGetParserOutput", to customize parser output for
33 a given content object.
34 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
35 * HTMLForm's HTMLTextField now supports the 'url' type.
36 * HTMLForm fields may now be dynamically hidden based on the values of other
38 * HTMLForm now supports multiple copies of an input field or set of input
39 fields, e.g. the form may request "one or more usernames" without having to
40 have the user enter delimited list of names into a text field.
41 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
42 the sidebar just before its display.
43 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
44 jquery.cookie so that getting/setting a cookie is syntactically and
45 functionally similar to using the WebRequest::getCookie() and
46 WebResponse::setcookie() methods.
47 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
48 $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
49 and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
50 This option is turned off by default, and will be removed in MediaWiki 1.25.
51 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
52 * Changes to content typography (fonts, etc.). See
53 https://www.mediawiki.org/wiki/Typography_refresh for further information.
54 * WikitextContent will now render redirects with the expected "redirect"
55 header, rather than as an ordered list. Code calling Article::viewRedirect
56 can probably be changed to no longer special-case redirects.
57 * Header font set to a serif font stack. See
58 https://www.mediawiki.org/wiki/Typography_refresh for further information.
59 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
60 the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
61 is only for page views, since this hook doesn't affect UserLogin, OAuth,
62 CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
63 overall design of the system.
64 * (bug 17367) It is now possible to add pages to your watchlist from
65 Special:UnwatchedPages without reloading the special page.
66 * New methods setVolatile and isVolatile are added to PPFrame, so that
67 extensions such as Cite.php can mark that their output is volatile and
69 * (bug 52817) Advanced search options are now saved on the search page itself,
70 rather than in a dedicated pane in the preferences panel.
71 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
72 the Vector skin has gained a label that should make it more discoverable.
73 * MWCryptHKDF added for fast, cryptographically secure random number generation
74 that won't deplete openssl's entropy pool.
75 * ResourceLoader: File modules can now provide a skip function that uses an
76 inline feature test to bypass loading of the module.
77 * (bug 20210) Special pages may now provide autocompletion of their subpage
78 names in search suggestions. Right now the only useful implementation is in
79 Special:Log, but more are to come.
80 * Special:MostLinkedTemplates is no longer limited to transclusions from the
82 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
83 This works the same as 'remoteExtPath' but is relative to the skins/ folder
84 instead of the extensions/ folder.
85 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
86 to 'name', to allow for the name to be localizable. 'name' should still be
87 specified for backwards-compatibility and to define the path Special:Version
88 uses to find extension license information.
89 * Browser tests are now included to verify basic wiki functionality in developer
90 environments. For details on running tests, see tests/browser/README.mediawiki.
92 === Bug fixes in 1.24 ===
93 * (bug 49116) Footer copyright notice is now always displayed in user language
94 rather than content language (same as copyright notice for editing interface).
95 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
96 restriction was present in the parameters. Images with both the "frame"
97 option and a size specification set will now always ignore the provided
98 size and display an unscaled image, as the documentation has always
100 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
101 which used to collapse some sidebar elements by default.
102 This removes -list id suffixes like p-lang-list: instead of using things like
103 #p-lang-list, you can do #p-lang .body ul.
104 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
105 follow redirects to their target pages.
106 * Parser now dies early if called recursively, instead of producing subtle bugs.
107 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
108 remaining page content.
109 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
110 in the file namespace and delete the file on the target page. It will still
111 however delete the redirect page.
112 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
113 recover the original code of extension tags.
115 === Web API changes in 1.24 ===
116 * action=parse API now supports prop=modules, which provides the list of
117 ResourceLoader modules that should be used to enhance the parsed content.
118 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
119 field which is true iff protocol-relative urls can be used to access
120 a particular interwiki map entry.
121 * ApiQueryLogEvents now provides logpage, which is the page ID from the
122 logging table, if ids are requested and the user has the permissions.
123 * action=edit now requires that appendtext, prependtext, or section=new be used
124 when using the 'redirect' parameter, to prevent clients accidentally
125 overwriting the target page with the content of the redirect.
126 * action=logevents will now return an error if both letitle and leprefix are
128 * action=logevents has a new parameter, lenamespace, to allow filtering by
130 * action=expandtemplates has a new parameter, prop, and a new output format.
131 The old format is still used if prop isn't provided, but this is deprecated.
132 * meta=userinfo can now return the count of unread pages on the watchlist.
133 * list=watchlist can now filter by unread status.
135 === Languages updated in 1.24 ===
137 MediaWiki supports over 350 languages. Many localisations are updated
138 regularly. Below only new and removed languages are listed, as well as
139 changes to languages because of Bugzilla reports.
141 === Other changes in 1.24 ===
142 * The deprecated jquery.delayedBind ResourceLoader module was removed.
143 * The deprecated function mw.util.toggleToc was removed.
144 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
145 were removed as they were unused.
146 * (bug 65477) User::pingLimiter() now has an additional profile point varying
147 by action being used.
148 * mediawiki.util.$content no longer supports old versions of the Vector,
149 Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
150 and/or "mw-body-primary" class name in their html.
151 * Added pp_sortkey column to page_props table, so pages can be efficiently
152 queried and sorted by property value (bug 58032).
153 See $wgPagePropsHaveSortkey if you want to postpone the schema change.
154 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
155 core to their own respective repositories. See also
156 https://www.mediawiki.org/wiki/Skin:Modern and
157 https://www.mediawiki.org/wiki/Skin:CologneBlue.
158 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
159 the "headelement" template key are no longer supported. Setting
160 $useHeadElement = false; is no longer supported and will not cause old keys
161 like "headlinks", "skinnameclass", etc. to be defined.
162 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
163 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
164 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
165 Special pages should subclass SpecialPage and implement the execute() method.
166 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
168 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
169 * The skin autodiscovery mechanism has been deprecated and will be removed in
170 MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
171 for migration guide for creators and users of custom skins that relied on it.
172 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
173 skin style files used by the module.
174 * Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
175 * Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
176 * Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
177 * Removed info(), purge(), revert() and rollback() from the Article class; they
178 have since become subclasses of the Action class. (deprecated since 1.19)
179 * SearchEngineReplacePrefixesComplete hook was removed.
180 * Removed HTMLForm::addJS(). (deprecated since 1.18)
181 * Removed LogEventsList::showHeader(). (deprecated since 1.19)

227 MediaWiki 1.24 requires PHP 5.3.2 or later.
229 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
230 support for them is somewhat less mature. There is experimental support for
231 Oracle and Microsoft SQL Server.
233 The supported versions are:
235 * MySQL 5.0.2 or later
236 * PostgreSQL 8.3 or later
237 * SQLite 3.3.7 or later
238 * Oracle 9.0.1 or later
239 * Microsoft SQL Server 2005 (9.00.1399)
243 1.24 has several database changes since 1.23, and will not work without schema
244 updates. Note that due to changes to some very large tables like the revision
245 table, the schema update may take quite long (minutes on a medium sized site,
246 many hours on a large site).
248 If upgrading from before 1.11, and you are using a wiki as a commons
249 repository, make sure that it is updated as well. Otherwise, errors may arise
250 due to database schema changes.
252 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
253 new database fields are filled with data.
255 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
256 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
259 Don't forget to always back up your database before upgrading!
261 See the file UPGRADE for more detailed upgrade instructions.
263 For notes on 1.23.x and older releases, see HISTORY.
