Microsoft has announced another new version, this time only a (very) minor update for those of us in version 19H2 Preview of the ring, with the build number up to 18363.387. According to the updated blog post, "This is just a small update of Build 18363.385 update with some fixes to uninstall 19H2 updates." and promised a 19H2 version (build 18363.xx) soon, and here it is. I could also follow the movements and try this if appropriate, we have come here :).
One good thing about these minor constructions is that we should be very close to a full 19H2 launch. Then move on to everything that remains to be tested for 20H1 and beyond.
