Apple released a new round of Developer Beta builds today, bringing the second betas of iOS 10.3, watchOS 3.2, and tvOS 10.2. The one OS that"s missing from the list is macOS 10.12.4 Sierra, the first build of which was released two weeks ago alongside iOS 10.3 and tvOS 10.2.
iOS 10.3 has a number of new features; Find my iPhone now has a feature to find your AirPods, there"s a Podcasts widget, iCloud calls are now supported on Verizon, there are weather forecasts in Maps, and you"ll find a new one-handed keyboard for the iPad. This build fixes some issues with iCloud Analytics, iCloud backup, managed and shared devices, and Xcode Simulator.
watchOS 3.2 adds a new Theater Mode, which will keep your Apple Watch from lighting up when you move your arm in a movie theater, and it supports SiriKit. This build fixes a few issues with SiriKit.
tvOS 10.2 adds some under-the-hood changes, such as support for the Apple File System. This build fixes issues with Mobile Device Management, TVMLKit, and and on demand resources.
It wouldn"t be surprising if Apple releases macOS 10.12.4 Sierra Developer Beta 2 within the next couple days, as they all tend to be released around the same time. If you"re on the Public Beta program, you should see the new iOS 10.3 build within a couple days as well.
