Ok, that's what I thought.
My initial reaction is that I would like to wait til 6.3.1 goes final (for a week or two) before having to update my board again.
My second assumption is that I'll also probably have to wait a few days to see if most of the hacks are compatible with the new version? (I'd prefer to let the real coders/programmers find the bugs first - they know how to handle them!!!)
Cheers.
