Messages on iCloud
We’ve all been waiting for the Messages on iCloud feature since June 2017. It was included in iOS 11.3 beta as well, but it wasn’t included in iOS 11.3 which was released to the public last week possibly because it was quite buggy in the beta versions.
For heavy iMessage users, this feature promises to get rid of 4-8 GB of conversations without actually having to delete anything. It also reduces the frustration of manually moving iMessage conversations every time you get a new phone.
Stereo Support for HomePod
iOS 11.4 beta 1 also includes Stereo support for HomePod, which means you will be able to add another two HomePod to create a stereo pair. However, it won’t work properly until the corresponding software update for HomePod is available.
