Apple today released new Developer Beta builds for all of its operating systems with the exception of macOS 10.12.4 Sierra. This includes beta 3 of iOS 10.3, watchOS 3.2, and tvOS 10.2.
iOS 10.3 has a number of minor new features, such as the ability to find Apple's new AirPods in the Find My iPhone app. There are also new weather options in Maps, as well as improvements to HomeKit and CarPlay.
The company fixed a number of issues in this release. For example, Location and Play Sound now works as expected for AirPods in Find My iPhone. Other issues were fixed with iCloud Analytics, iCloud Backup, LAN Asset Cache, Lightning video adapters, managed and shared devices, and Xcode Simulator.
watchOS 3.2 adds SiriKit, as well as a new Theater Mode. Turning on Theater Mode will stop the screen from waking up when you lift the watch. Unfortunately, there are no release notes for this build, as the link redirects to the tvOS changelog. We'll keep you updated as they show up and there's anything worth noting.
As for tvOS 10.2, that will convert the device to the Apple File System (APFS), much like iOS 10.3. The new build comes with a few notes and known issues that have to do with Accelerated Scrolling, Device Enrollment Program (DEP) / Mobile Device Management (MDM), and Top Shelf App Extension.
Aside from those, there are also new betas for Apple Configurator 2.4, macOS Server 5.3, the Classroom 2.0 app, and Xcode 8.3. You can find them all at Apple Developer.
Update: macOS 10.12.4 Sierra beta 3 is now available to developers.
