6.2.1 == "beta" 9. Yeah, it is.
6.2.2 == "beta"... prolly 15 or 16.
In the world of software, there is never final, nor stable.
With the exception of a handful of minorly broken things, the entire 6.2 beta and release versions have been relativly bug free.
We could probably get away with releasing the current 6.2.2 as a public beta and not encounter a single issue...
... however, we have lots more planned for it.
