We don't yet know what improvements the sixth update to macOS High Sierra will bring, but it likely focuses on bug fixes and performance improvements for issues that were not able to be addressed in macOS High Sierra 10.13.5.

We'll update this post if any new features or notable bug fixes are discovered in the new macOS 10.13.6 beta.

Work on macOS High Sierra is wrapping up, with Apple now shifting focus to the next-generation version of macOS, macOS 10.14, which will be unveiled next week at the Worldwide Developers Conference.

Bizarre. Can't remember the last time the next beta came before the previous version's final release.

I think they are holding it because a new mac is coming on 4th, and there is something in 10.13.5 about new Mac that they dont want us to know yet
my thoughts exactly!
Just intuition , there is something in 10.13.5 about new Mac that they don't want us to know yet, could be new macbook, or air or mini, any mac
This wouldn't be necessary. They would just have a special build for the new Mac. They've done it multiple times before.
