Update atv flash and apps

Just wondering how to update atv flash when next update is coming? Is there an automatic option for update in maintenance or do i have to do i manually like i did with the first installation?
Same quastion wit apps like xbmc or couchsurfer? How will we be able to update these?

You can update Couch Surfer and XBMC the same way you installed them, I will just give you the option. I'm not sure how they roll out Flash updates.
