Apple has just released the first beta versions of watchOS 4.2 along with tvOS 11.2 to registered developers.
Here are the changes in tvOS 11.2 with two focusing on the Apple TV 4K:
tvOS 11.2 includes new features, bug fixes, and security improvements in the OS and SDK, including:
– Automatic mode switching to native frame rate and dynamic range of video content with Apple TV 4K
– Support for switching Apple TV 4K display output to SDR for apps that are GPU-bound when running in HDR
– Restoring Unwatched category in Home Sharing for Movies, TV Shows, and Home Videos
We’re also expecting Apple to release watchOS 4.1 and tvOS 11.1 to the general public sometime this week. Both of those software versions have gone through four beta versions.
