Apple is preparing to launch watchOS 10.2, a significant update for the Apple Watch that introduces new features. The update has been undergoing testing by developers through three beta versions, with the fourth and latest beta released recently.
The fourth beta of watchOS 10.2 has a build number of 21S5358a. The update size varies depending on the current version of the Apple Watch. For those who are running the stable version of watchOS 10.1.1, the update is approximately 542MB. For those who are already on a previous beta version, the update is smaller.
The access to watchOS 10.2 is currently restricted to registered Apple developers. However, the update is expected to be publicly available soon for early adopters who want to experience the new features firsthand.
One marquee capability arriving in beta 4 is Contact Key Verification for iMessage, a major security enhancement that should prove especially valuable for government personnel, journalists, human rights activists and more. Additional promising developments are likely as the software continues to evolve.
This new verification functionality promises robust protection against severe online threats once the finished update is launched.
