Apple has just posted a fifth set of developer betas for iOS 11.4, tvOS 11.4, and watchOS 4.3.1, again only a week after the fourth round of betas went out. Unsurprisingly, the release notes at this point list only extremely minor changes since the last beta, and it remains unclear whether iOS 11.4 and tvOS 11.4 will in fact incorporate AirPlay 2, which also made a brief appearance in the iOS 11.3 betas earlier this year before being removed before the final release, a fate similar to that of Messages in iCloud, which is still listed in the release notes as being included “for testing and evaluation purposes.”
