Apple rolls out release candidate beta for watchOS 10.3

A fourth developer beta of watchOS 10.3 has been released for testing as the release candidate.

Developers participating in the beta program can pull the latest version via the Apple Developer Center or simply by updating their devices with the beta software. Public beta releases are usually available a brief period after the developer releases, via the Apple Beta Software Program.

The fourth developer beta for watchOS 10.3 arrives after the third, introduced on January 9, while the second round occurred on January 3.

So far, it doesn't seem like there are any major new features in watchOS 10.3, so it may end up being a bug fix and performance improvement fix release.

The fourth build of watchOS 10.3 is number 21S644, replacing the third, 21S5642a.

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.
