Second and third generation Apple TV boxes have a new software update to keep an eye out for, and now that the changelog has been posted for 5.0.1 we can see what it brings. According to this screen grab from Apple's support page, the update adds HD previews for TV shows and movies in the iTunes store, and fixes issues affecting AirPlay, Home Sharing, Netflix and more. Of course, FireCore warns jailbroken fans to stay away from the update button for now, all others should get a prompt on their hockey puck sooner rather than later.
