lol, I'm actually packaging 4.21 as an upgrade to our environment as we speak ! (we're still running 3.5x believe it or not). Going to be deploying in a few months ... and I'm happy just thinking about it ... [Wink]

Truthfully, 4.21 seems to be the best release since (oh, way back) to 4.02 ... dont think I would touch anything other than those two.
