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 1.22 is an alpha-quality branch and is not recommended for use in
11 === Configuration changes in 1.22 ===
12 * $wgRedirectScript was removed. It was unused.
13 * Removed $wgLocalMessageCacheSerialized, it is now always true.
14 * When $wgUseVFormUserLogin is true, the redesign of Special:UserLogin is
16 * $wgVectorUseIconWatch is now enabled by default.
18 === New features in 1.22 ===
19 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
20 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
21 the "eIOPTZ" formatting characters.
22 * EditWarning: A warning is shown when an editor leaves the edit form without
23 saving (enabled by default, users can opt-out via the 'useeditwarning'
24 preference). This feature was moved from the Vector extension, and is now part
25 of core for all skins. Take care when upgrading that you don't use an older
26 version of the Vector extension as this feature may conflict.
27 * New version of Special:UserLogin form. It is opt-in for now, controlled by
28 the $wgUseVFormUserLogin setting or a 'useNew' URL parameter trigger.
29 * Added 'SpecialSearchResultsPrepend' and 'SpecialSearchResultsAppend' hooks.
30 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
31 by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
33 === Bug fixes in 1.22 ===
34 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
35 navigate to the page by entering the URL directly.
36 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
37 create an account on login due external authentication in some circumstances.
38 * (bug 23393) HTML <hN> headings containing line breaks are now handled
40 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
41 is now non-significant and not preserved in the HTML output.
43 === API changes in 1.22 ===
44 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
45 parameter has had no effect since MediaWiki 1.16, and so its removal is
46 unlikely to impact existing clients.
47 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
48 to action=feedwatchlist.
49 * WDDX formatted output will actually be formatted (and normal output will no
50 longer be), and will no longer choke on booleans.
51 * action=opensearch no longer silently ignores the format parameter.
52 * action=opensearch now supports format=jsonfm.
54 === Languages updated in 1.22===
56 MediaWiki supports over 350 languages. Many localisations are updated
57 regularly. Below only new and removed languages are listed, as well as
58 changes to languages because of Bugzilla reports.
60 === Other changes in 1.22 ===
61 * redirect.php was removed. It was unused.
62 * ClickTracking integration was dropped from the mediaWiki.user.bucket
63 JavaScript function. The 'tracked' option is now ignored.
64 * BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
65 Nostalgia was moved to an extension.
66 * Event namespace used by jquery.makeCollapsible has been changed from
67 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
68 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
69 with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
70 $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
71 use AuthPlugin for external authentication/authorization needs.
72 * The Quickbar feature of the legacy skin model and the last remnants of it
73 throughout the code base have been removed.
74 * Externaledit/externaldiff preference was removed. Very few users used this
75 feature, and improper configuration can actually prevent a user from editing
76 * Calling Linker methods using a skin will now output deprecation warnings.
77 * (bug 46680) "Return to" links are no longer tagged with rel="next".
78 * The Special:ActiveUsers special page was removed.
82 MediaWiki 1.22 requires PHP 5.3.2 or later.
84 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
85 support for them is somewhat less mature. There is experimental support for
88 The supported versions are:
90 * MySQL 5.0.2 or later
91 * PostgreSQL 8.3 or later
92 * SQLite 3.3.7 or later
93 * Oracle 9.0.1 or later
97 1.22 has several database changes since 1.21, and will not work without schema
98 updates. Note that due to changes to some very large tables like the revision
99 table, the schema update may take quite long (minutes on a medium sized site,
100 many hours on a large site).
102 If upgrading from before 1.11, and you are using a wiki as a commons
103 repository, make sure that it is updated as well. Otherwise, errors may arise
104 due to database schema changes.
106 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
107 new database fields are filled with data.
109 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
110 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
113 Don't forget to always back up your database before upgrading!
115 See the file UPGRADE for more detailed upgrade instructions.
