(Not really an issue just trying to help people that might not catch this)
As Aviana said there's some config options that might default or not work immediately.

If you normally have Raid > Show When: Party/Always/Raid enabled, on first load your character will not appear in the raid frame if you are in a group.

You have to re-select your preferred option with the update.

(at least I hope and think this was just a one time bug)
