Apple today released the final version of tvOS 9.2.1 for the 4th generation Apple TV. The update includes general performance and stability improvements. No new features were added in this release.
You can update your Apple TV by going to Settings > System > Software Updates > Update Software.
It is highly expected that Apple will unveil the next-generation operating system for the new Apple TV at this year’s WWDC that will be held between June 13-17 in San Francisco.
Back in March Apple released tvOS 9.2 software update for Apple TV 4, a major update that brought folders for grouping apps on the home screen, support for Bluetooth keyboards, new Siri languages and an updated app switcher UI to the new Apple TV.
