Apple issues new public & developer iOS 10.2, macOS 10.12.2 betas, plus dev-only watchOS 3.1.1 beta

Release notes accompanying each of the three betas offer little information about what the updates include beyond maintenance changes. The short cycle on the iOS beta — just days after the last update — at least suggests that a release is imminent.

Major additions for iOS 10.2 include a selection of fresh wallpapers and emoji characters, which debut alongside minor additions like new first-party widgets and system settings tweaks.

iOS 10.2 and tvOS 10.1 will also add single sign-on support for streaming TV, allowing users subscribed to cable, satellite, or online-only services to access channels across multiple apps without constantly re-authenticating.

Apple has previously said that its "TV" app will launch on iOS and tvOS as a free software update in December.

Monday's iOS 10.2 update comes hot-on-the-heels of Friday's fifth iOS beta, which makes for three iOS updates in eight days.

Developers can download the latest beta releases from Apple's developer webpage or directly on test devices via Software Update. Public beta participants can get the software as an over-the-air update if they're already registered in the program.
