The new Apple TV it started to be sold a few days ago. And, for those who already have one, the company has just made the first update available for the set-top box.
To download the tvOS 9.0.1 (compilation 13T402), just go to Software Update System Settings this is if the option to download updates automatically is not enabled, of course. Bearing in mind that tvOS 9.1 beta is already being tested, everything indicates that Siri will become compatible with Apple Music in this version.
The update probably only brings general bug fixes and performance improvements, as expected from a .0.1.
