Today, Apple released the first developer betas for iOS 11.2, watchOS 4.2, and tvOS 11.2. The news comes while iOS 11.1, watchOS 4.1, and tvOS 11.1 are all still in beta, so it"s safe to assume that those will be released soon.
The iOS 11.2 release notes just show a bunch of known issues. Most of them have to do with the developer end of things, but one thing to be aware of is that if you charge your iPhone on a dock, charging your phone without the dock will require you to restart the device. You"ll also find that playing a podcast with chapter markers will cause the Podcasts app to crash.
There are only two known issues for watchOS 4.2. iTunes sign-in may fail when you"re pairing the device, and app icons may appear as placeholder images.
As for tvOS 11.2, there should be a range of fixes for those that are using the new Apple TV 4K with 4K TVs. There"s automatic mode switching to native frame rate and dynamic range, and support for switching the display output to SDR for GPU-bound apps.
These builds are only for developers right now, but iOS and tvOS Public Beta testers should see them within the next couple of days.
