Apple has released iOS 11.4 Beta 1 to those enrolled in its public beta testing program. Apple made the same beta available to developers earlier this week.
The build includes several features that were meant to included in iOS 11.3, but didn’t make the final release.
These include AirPlay 2 and Messages on iCloud, which allows people to store their iMessage content in the cloud and sync it across devices.
The beta is free to download from Apple.
