As of right now, watchOS 9.5 is only available to registered Apple developers. You can update your Apple Watch by going to Settings, choosing General, then choosing Software Update. You can also install the update via the Apple Watch companion app on your iPhone.
The build number of watchOS 9.5 beta 1 is 20T5527c.
It remains to be seen what, if anything, is new in watchOS 9.5. Apple just released watchOS 9.4 to everyone on Monday. This update included a few new features, such as the expansion of AFib History and Cycle Tracking to new countries.
watchOS 10 is just a few months away, as Apple is expected to announce the update at WWDC in June. As we approach that debut, we expect watchOS 9 updates to become smaller in scope.
