* Added support in jquery.localize for placeholder attributes.
* (bug 38151) Implemented mw.user.getRights for getting and caching the current
user's user rights.
+* Session storage can now configured independently of general object cache
+ storage, by using $wgSessionCacheType. $wgSessionsInMemcached has been
+ renamed to $wgSessionsInObjectCache, with the old name retained for backwards
+ compatibility.
* Implemented mw.user.getGroups for getting and caching user groups.
* (bug 37830) Added $wgRequirePasswordforEmailChange to control whether password
confirmation is required for changing an email address or not.
