Apple makes available fifth developer beta releases of iOS 10.3, watchOS 3.2, and tvOS 10.2

The latest iOS 10.3 beta with build number 14E5269a includes a new Find My AirPods, migration to APFS, and a new reviews API which limits how often an app can ask users to submit ratings on the App Store.

Also included in the iOS update is iCloud-connected device calling for Verizon customers, and a floating one-handed keyboard for iPad users.

Instead of just telling the user that the application may cause slow-downs of the device like in iOS 10.2, all 10.3 beta releases warn the user that an upcoming version of iOS will drop support for 32-bit apps entirely. Apple has not made clear what version that it, but iOS 11 is expected at the 2017 WWDC.

A new theater mode has been included with the watchOS 3.2 betas, 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. The build number on the fifth watchOS beta is 14V5243a.

Apple hasn't drawn a great deal of attention to tvOS 10.2, but the betas have so far added accelerated scrolling, support for the Device Enrollment Program, and wider mobile device management (MDM) options, according to Apple notes.

The full tvOS 10.2 release is expected to implement support for the VideoToolbox framework, which lets people tap directly into hardware-accelerated encoding and decoding functions. The framework is already present in iOS and macOS.

The build number on Wednesday's beta is 14W5260a.

Wednesday's releases follow Tuesday's debut of the fifth beta for macOS Sierra 10.12.4. Also released on Wednesday is the fourth beta release of Xcode 8.3, including support for all the new features in the betas.

Developers can update to the newest beta releases using the software update feature for iOS, and from the Mac App Store with registered hardware. Those interested in testing beta software before wide release can sign up for Apple's program via the company's official website.
