Re: [Wikitech-l] does upgrading MediaWiki cause users to need to login again?

I don't believe this would break a session, however; the object should be recreated fresh, authenticated from the login token in the session. If it's a reproducible problem, it should be possible to track it down. Double-check that it's not a basic problem with sessions; for instance sessions in memcached being broken by an upgrade process that includes restarting memcached, or some change to the memcached hashing (which shouldn't have happened); or an unrelated update to PHP wiping old session data; or the newer MediaWiki version simply using a different session name than the old one. - -- brion
