It changes quite a lot of things, and there is certainly a concern that it's not as compatible as it was. Things I think it addresses fairly well now:
15 minute working day
Simplification of rules (Grappling, polymorph)
Improving 1st level survival
Improved Skills
Smoother management of encounters/CRs
I think there are still quite a few areas which are more problematic to address:
High level NPCs
High level Play/DMing
Christmas Tree Effect
Combat Tracking (buff spells, etc.)
The Beta will hopefuilly improve the compatibility and some of the other issues that are still outstanding. But it is difficult to address some issues without breaking compatibility completely, and at the same time given the vast amounts of Wotc (i.e. non-OGC) material out there that people use (the Complete books for example) it will never be entirely compatible.
