Without even so much as an announcement, Apple has updated AppleTV to iOS 4.3, build 8F455. The official AppleTV software page doesn’t reflect the change, but we’re hearing about it from a number of sources. The big change is that it seems to add support for streaming of purchased content:
You can buy — not just rent but buy — new episodes directly from your Apple TV, and access and stream any TV show episodes you’ve previously purchased using your iTunes account. (I’m not quite sure if it has all episodes — but it’s showing me all the TV shows I can remember buying from iTunes.)
TV shows are also now listed in the “Purchased” section of the iTunes Store on your computer, iPhone, and iPad. In other words, Apple just rolled out a cloud-based storage locker for TV shows. Next up (I hope): movies.
Apparently this update also adds support for Vimoe and YouTube playlists.
Unfortunately, we’re also hearing that it’s USA only for now.
