Mythic keeps churning out patches and tomorrow 1.01 will be applied to the live servers. There's a bunch of fixes ("and more!", according to the notes), a lot of them dealing with the chat windows that can get quite troublesome.
I can't see the patch notes mentioning that you have to rejoin any non-default channels every time you log in, or that chat channels never get "sticky" like party- or guild-chat. Very annoying to have to write the channel number every time you want to say something. World of Warcraft had to fix that through an addon, so I am not really holding my breath for Mythic to do it either...
Other good news include tab-targetting working better (it's a mess right now), some PQs getting some bug fixes and a whole dungeon - Lost Vale - being closed down to fix stuff inside it before opening it up again. Not the world's most exciting patch at first glance, but there's a couple of tidbits in there that should make for a smoother experience.
