Apple Releases Fourth watchOS 26.5, tvOS 26.5 and visionOS 26.5 Betas
Source: MacRumors
Apple today provided developers with the fourth betas of upcoming watchOS 26.5, tvOS 26.5, and visionOS 26.5 for testing purposes. The software arrives a week after Apple released the third betas for each platform.

The updates are available through the Settings app on each device, and because these are developer betas, a free developer account is required.
There’s no word yet on what’s inside the software. watchOS, tvOS, and visionOS typically introduce only a few features in each new beta, with most changes focused on bug fixes and performance improvements. Nothing new was found in the first three betas.
