production.
=== Configuration changes in 1.22 ===
+* $wgRedirectScript was removed. It was unused.
+* Removed $wgLocalMessageCacheSerialized, it is now always true.
+* When $wgUseVFormUserLogin is true, the redesign of Special:UserLogin is
+ activated.
=== New features in 1.22 ===
+* (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
+* (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
+ the "eIOPTZ" formatting characters.
+* EditWarning: A warning is shown when an editor leaves the edit form without
+ saving (enabled by default, users can opt-out via the 'useeditwarning'
+ preference). This feature was moved from the Vector extension, and is now part
+ of core for all skins. Take care when upgrading that you don't use an older
+ version of the Vector extension as this feature may conflict.
+* New version of Special:UserLogin form. It is opt-in for now, controlled by
+ the $wgUseVFormUserLogin setting or a 'useNew' URL parameter trigger.
=== Bug fixes in 1.22 ===
+* Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
+ navigate to the page by entering the URL directly.
+* (bug 47138) Fixed a fatal error when a blocked user tries to automatically
+ create an account on login due external authentication in some circumstances.
=== API changes in 1.22 ===
+* (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
+ parameter has had no effect since MediaWiki 1.16, and so its removal is
+ unlikely to impact existing clients.
=== Languages updated in 1.22===
changes to languages because of Bugzilla reports.
=== Other changes in 1.22 ===
-
+* redirect.php was removed. It was unused.
+* ClickTracking integration was dropped from the mediaWiki.user.bucket
+ JavaScript function. The 'tracked' option is now ignored.
+* BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
+ Nostalgia was moved to an extension.
+* Event namespace used by jquery.makeCollapsible has been changed from
+ 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
+* BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
+ with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
+ $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
+ use AuthPlugin for external authentication/authorization needs.
+* The Quickbar feature of the legacy skin model and the last remnants of it
+ throughout the code base have been removed.
+* Externaledit/externaldiff preference was removed. Very few users used this
+ feature, and improper configuration can actually prevent a user from editing
