Daring Fireball is saying that a new software update for Apple TV has hit and it's a good one: you can finally buy TV shows from your Apple TV and stream any TV shows you've previously purchased from iTunes.
This is great. The stuff you bought is no longer trapped in the purgatory of iTunes and can now conveniently be watched on the big screen. It's all working in "the cloud" and is pretty damn convenient for anyone who has bought a lot of TV shows from iTunes. No support for movies yet though. Additionally, the update has added support for Vimeo. [Daring Fireball]
