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
17 === New features in 1.22 ===
18 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
19 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
20 the "eIOPTZ" formatting characters.
21 * EditWarning: A warning is shown when an editor leaves the edit form without
22 saving (enabled by default, users can opt-out via the 'useeditwarning'
23 preference). This feature was moved from the Vector extension, and is now part
24 of core for all skins. Take care when upgrading that you don't use an older
25 version of the Vector extension as this feature may conflict.
26 * New version of Special:UserLogin form. It is opt-in for now, controlled by
27 the $wgUseVFormUserLogin setting or a 'useNew' URL parameter trigger.
29 === Bug fixes in 1.22 ===
30 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
31 navigate to the page by entering the URL directly.
32 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
33 create an account on login due external authentication in some circumstances.
35 === API changes in 1.22 ===
36 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
37 parameter has had no effect since MediaWiki 1.16, and so its removal is
38 unlikely to impact existing clients.
40 === Languages updated in 1.22===
42 MediaWiki supports over 350 languages. Many localisations are updated
43 regularly. Below only new and removed languages are listed, as well as
44 changes to languages because of Bugzilla reports.
46 === Other changes in 1.22 ===
47 * redirect.php was removed. It was unused.
48 * ClickTracking integration was dropped from the mediaWiki.user.bucket
49 JavaScript function. The 'tracked' option is now ignored.
50 * BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
51 Nostalgia was moved to an extension.
52 * Event namespace used by jquery.makeCollapsible has been changed from
53 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
54 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
55 with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
56 $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
57 use AuthPlugin for external authentication/authorization needs.
58 * The Quickbar feature of the legacy skin model and the last remnants of it
59 throughout the code base have been removed.
60 * Externaledit/externaldiff preference was removed. Very few users used this
61 feature, and improper configuration can actually prevent a user from editing
65 MediaWiki 1.22 requires PHP 5.3.2 or later.
67 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
68 support for them is somewhat less mature. There is experimental support for
71 The supported versions are:
73 * MySQL 5.0.2 or later
74 * PostgreSQL 8.3 or later
75 * SQLite 3.3.7 or later
76 * Oracle 9.0.1 or later
80 1.22 has several database changes since 1.21, and will not work without schema
81 updates. Note that due to changes to some very large tables like the revision
82 table, the schema update may take quite long (minutes on a medium sized site,
83 many hours on a large site).
85 If upgrading from before 1.11, and you are using a wiki as a commons
86 repository, make sure that it is updated as well. Otherwise, errors may arise
87 due to database schema changes.
89 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
90 new database fields are filled with data.
92 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
93 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
96 Don't forget to always back up your database before upgrading!
98 See the file UPGRADE for more detailed upgrade instructions.
