After releasing macOS 10.12.4 Sierra Developer Beta 2 earlier today, Apple is offering the second iOS 10.3 build to Public Beta testers. The news comes just a day after it was seeded to developers, alongside watchOS 3.2 and tvOS 10.2.
There aren't really any new front-facing features in today's build, but there are some fixes, which have to do with iCloud Analytics, iCloud backup, managed and shared devices, and Xcode Simulator.
The update itself does bring a few features that are worth noting. You'll find that you can now bring up weather forecasts in Maps, there's a Podcasts widget, Find my iPhone can now find your AirPods, iCloud calls are now supported on Verizon, and more.
If you're on the Apple Beta Software Program, the update is available now. If not, you can always sign up for it here. For those that are anxiously awaiting the new macOS 10.12.4 Sierra beta that includes Night Mode, that one will probably show up at some point tomorrow.
