At a very fast pace of testing, Apple had released last Friday iOS 11.1 beta 4 and watchOS 4.1 beta 4.
Today, the fourth beta versions of the macOS High Sierra 10.13.1 (compilation 17B45a) and tvOS 11.1 (15J5582a), as well as the fifth iOS 11.1 (15B93).
These new compilations are available for developers only, but will soon be painted for members of the Apple Beta Software Program as well.
The feedback from those who are already testing them all could not be better, as we have heard. It seems that now Apple got it right!
