Apple today seeded the second beta of an upcoming tvOS 11.2 update to developers for testing purposes, one week after seeding the first tvOS 11.2 update and a little under a week after the launch of the tvOS 11.1.
Designed for the fourth and fifth-generation Apple TV models, the tvOS 11.2 developer beta can be downloaded onto the Apple TV via a profile that’s installed using Xcode.
According to Apple’s release notes, the tvOS 11.2 update enables a new AVDisplayManager feature for developers, designed to allow the device to automatically switch video display modes to match the native frame rate and dynamic range of video content.
The update includes support for switching the Apple TV 4K display output to SDR for apps that are GPU-bound when running in HDR and it re-introduces the Unwatched category in Home Sharing for Movies, TV Shows, and Home Videos.
Apple says it also adds new features, bug fixes, and security improvements to the tvOS operating system.
