Apple Releases Second watchOS 26.4, tvOS 26.4 and visionOS 26.4 Betas
Source: MacRumors
Apple today provided developers with the second betas of upcoming watchOS 26.4, tvOS 26.4, and visionOS 26.4 for testing purposes. The software comes a week after Apple released the first betas.

The updates are available through the Settings app on each device, and because these are developer betas, a free developer account is required.
watchOS 26.4
- Adds a new Average Bedtime metric to the Sleep features that sync to the Health app, helping users track how bedtime impacts overall sleep quality.

tvOS 26.4
- Eliminates the iTunes Movies and iTunes TV Shows apps on Apple TV, which have been non‑functional for some time and have redirected users to the Apple TV app for purchases. Apple is now phasing them out entirely.
Details on the removal - Introduces a Continuous Audio Connection option for HDMI output.
visionOS 26.4
- Includes support for foveated streaming for apps and games. Foveated streaming delivers video at full quality only to the area where the user is looking, compressing peripheral regions. This results in higher visual quality and lower latency.
