Sure, but whether or not 3.x changed significantly from 2.x isn't really what I'm asking about, I was more wondering if you imagined upon the release of 3 (or 2 for that matter) that it was more or less the final stable overall design, or were significant future redesigns/rewrites still in the plan at that point?
