Apple has seeded the fourth developer betas of watchOS 26.5, tvOS 26.5, and visionOS 26.5 for testing.
The build numbers for today's releases are 23T5568a for watchOS, 23L5469a for tvOS, and 23O5468a for visionOS. The updates were released alongside iOS 26.5 beta 4 and iPadOS 26.5 beta 4.
Apple has not shared detailed release notes for these builds, and no major new features have surfaced yet. The updates appear to focus on performance improvements and bug fixes.
These releases follow the public rollout of version 26.4 across the ecosystem late last month. That update added support for AirPods Max 2 and HLS video podcasts on Vision Pro, removed legacy iTunes apps from Apple TV, and introduced a quick-start Workout toggle on Apple Watch.
Registered developers can download the updates by navigating to the Software Update section in Settings on their respective devices. The watchOS update must be installed through the Watch app on a paired iPhone.
