Apple has provided developer beta participants with a fresh second build of watchOS 10.2 to test out on their devices.
Developers participating part in the beta program can get the latest builds via the Apple Developer Center or by updating their devices with the beta software. Public beta versions are usually provided a short time after the developer releases, via the Apple Beta Software Program.
The second developer beta for watchOS 10.2 arrives after the first beta, which landed on October 26.
The second build of watchOS 10.2 is number 21S5342e, replacing the first, 21S5331f.
At this early stage, it is unclear what changes there are in watchOS 10.2, aside from the usual collection of bug fixes and performance improvements typical of Apple's updates.
AppleInsider and Apple strongly suggest users don't install beta operating systems or other beta software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
