Apple has been pushing out iOS betas at a pretty fierce pace lately. It released iOS 10.2 beta 4 on November 28, followed by beta 5 a few days later on December 2. Today, it's already rolling out another new preview release.
iOS 10.2 beta 6 (build 14C90/14C91) is now available, both for developers and those on the Public Beta program. The final version of iOS 10.2 is likely to be released for all non-beta users later this month.
The newest version of Apple's mobile OS will bring various new features, including the company's TV hub app, dozens of additional emoji, and a new Emergency SOS feature that will call 911 (or your country's equivalent emergency services number) if you push the power/wake button five times in a row. It will also bring other minor tweaks, such as the option to preserve camera settings, along with various bug fixes and stability improvements.
Meanwhile, Apple has also released macOS 10.12.1 beta 5, bumping the build number up to 16C60b, following the fourth beta's arrival last month. Unlike the latest iOS beta, the new macOS release is exclusively for devs.
And finally, developers can also get their hands on watchOS 3.1.1 beta 5. As its version number suggests, that update will be a minor one, focusing on bug fixes. Like iOS 10.2, the final versions of the macOS and watchOS updates are expected to be released to the public before the year's end.
