Sometime between Thursday, 2008-05-15 and today (2008-05-18) the AutoAuthenticate stopped being called on page loads. I am using the http://www.mediawiki.org/wiki/Extension:LDAP_Authentication plugin, which until this updated, prompted a user for a login on page load when a non-authenticated user visited the wiki. Now, it sets $wgHooks['AutoAuthenticate'][] = 'fnMyHook'; but 'fnMyHook' (for example) is never called.
It seems that the hook was renamed to UserLoadFromSession according to the release notes - sorry for the invalid bug.
