Apple has released the first developer betas of watchOS 26.4, tvOS 26.4, and visionOS 26.4 for testing. The software updates arrived just days after the 26.3 versions launched for each platform. Developer accounts are required to access these beta versions through the Settings app on each device.

While Apple hasn't detailed all the changes, the updates are expected to introduce new emoji characters and potentially enhanced Siri capabilities. The company typically uses beta releases to test new features before wider deployment. These incremental updates follow Apple's regular software release cycle for its ecosystem of devices.

Public beta testers will likely gain access to the tvOS 26.4 and watchOS 26.4 betas later this month, though visionOS 26.4 will remain limited to developers. The software updates are scheduled to launch in mid-to-late March, continuing Apple's pattern of regular platform updates across its device lineup.
