Apple has updated the Apple TV software to version 7.0. This new version works only on the third-generation Apple TV. It refreshes the interface with an iOS 7-style aesthetic, though the steps for navigating in the interface haven’t much changed, just the look. Apple has also rolled out the new Beats Music app, which is available only in the new Apple TV 7 software. Read my TidBITS article, Apple TV Updated to 7.0, Includes Beats Music to see how it looks.
