Apple felizola the first beta of iOS 11.4 for developers. The main innovation is the support ClassKit presented at a recent presentation with iPad’s 9.7 inches. Also came tvOS 11.4 Beta 1 and watch OS 4.3.1 Beta 1, which received no significant changes.
The first beta of iOS 11.3, the company added AirPlay 2, but then the function cut. In iOS 11.4 she returned. However, to combine the HomePod in a stereo pair need the same beta version on all the speakers — when I try to connect a warning will appear about the necessary update.
In addition, in the iCloud settings back switch backup messages in iMessage. He was also in the bet iOS 11.3, but before the final release, the feature is not there.
iOS 11.4 will be released in June, and that means AirPlay the 2 before this time we will not see.
