As a watch, Apple continues to release new trial versions of its operating systems weekly. A week after Wednesday, the fifth beta of the iOS 12.1 (compilation 16B5089b) of tvOS 12.1 (16J5602a) and watchOS 5.1 (16R5589c).
What's new for iOS 12.1, as we've said, includes Dual SIM support on the XS / XS Max / XR iPhones, group FaceTime (also on macOS, of course, and even watchOS only on audio) and a choice of adjust the depth of photos before you take them.
For now, the new trial versions of iOS and tvOS have not yet appeared in the Apple Beta Software Program (watchOS is not part of the program); We'll let you know when that happens. We will also be watching for the release of the macOS Mojave 10.14.1 beta 5, which has not yet occurred.

As expected, today was the day of macOS Mojave 10.14.1 beta 5 (build 18B73a) to be released to developers. Soon, an equivalent version of tests should also paint in the Apple Beta Software Program.
