I think you're reading it wrong there; this is not a statement of "3.0 came out and then they kept breaking compatibility all the time until 3.3", it's a statement of "3.0 declared what the changes were so people could play with the new APIs, and then 3.1, 3.2 and 3.3 spent time on performance and making porting easier so that people could actually port to and deploy on later 3.x releases".
