Are you saying that there are several 4.2.2 versions sharing the same release number?
If that's so then it doesn't sound sensible at all. Shouldn't be hard to append a 4th number to reflect minor fixes.
Anyway, we installed "our version of the 4.2.2 version" on March 14 (5 days ago). Not going to push anything newer than 4.2.1 until we see a bump in the version number or get proper feedback.
All the best,
