Apple releases sixth betas of macOS 10.12.4, iOS 10.3 to developers [u]

Apple on Monday made available a sixth beta releases of macOS 10.12.4 and iOS 10.3 to developers, marching ever closer to a public release. [Updated with info on public betas]

The main feature addition to macOS 10.12.4 is Night Shift, a carryover of a feature first introduced to iPhones and iPads with iOS 9.3. As on those devices, Night Shift for Mac gradually warms color temperatures to reduce exposure to blue light, which can potentially help people get to sleep more easily.

The 10.12.4 update also expands dictation support to more languages, adds better PDFKit APIs, and enables cricket scores in Siri. Other focus areas include iCloud Analytics, and standard bugfixes and performance tweaks.

Beta 6 of macOS 10.12.4 has build number 16E189a

The iOS 10.3 beta 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 iOS 10.3 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 is, but iOS 11 is expected at the 2017 WWDC.

The latest iOS 10.2 beta has build number 14E5273a.

It's not clear when the finished versions of macOS 10.12.4 and iOS 10.2 will be available, but the first beta appeared in late January. Few releases take more than six betas, with only OS X 10.8.3 reaching as many as 10.

Update: Apple has also released public betas of both updates, which should be available to anyone registered with the official Beta Software Program.
