Less than a week after Apple released the third betas for iOS 11.4, tvOS 11.4, and watchOS 4.3.1, the company is back with its fourth round of developer betas.
As expected, the release notes list only very minor changes, and although Messages in iCloud and AirPlay 2 support remain in place in iOS 11.4 beta 4, it’s unclear whether these will still make it into the final release.
At this point, AirPlay 2 is only available with Apple TV devices running the tvOS 11.4 beta, although the HomePod will presumably get a similar 11.4 update by the final release — Apple is not making beta software available for the HomePod at this point.
