Zune update leaked?

A Zune user told the other Zune user on zunerama that somehow Microsoft pushed out an updated version of the Zune software, version 2.1.0522.00. It doesn’t seem to do anything more than just sit there right now, but is this a look at Zune software to come? A failed update that frightened the masses?
