Nearly two weeks since the last release, Apple has made available the third betas of iOS 10.3, watchOS 3.2, and tvOS 10.2 available to developers.
The latest iOS 10.3 beta includes implementation of APFS, a new Find My AirPods , and a new reviews API which limits how often an app can ask users to submit ratings on the App Store. Also implemented is iCloud-connected device calling and a floating one-handed keyboard for iPad users.
Also, an upcoming version of iOS will drop support for 32-bit apps entirely, according to an error message discovered in the first iOS 10.3 beta, which persists to the current release.
A new theater mode has been included on watchOS 3.2, enabling users of the device to prevent the screen from automatically turning on when the user's wrist is raised without completely turning off the device.
It is not yet known what new features, if any, tvOS 10.2 will have.
Developers can update to the newest beta releases using the software update feature on registered devices.
