By rewrite, do you mean just incorporating new features?
I try very hard to make sure that each version is fully backwards compatible (excluding "hackish" code). Is there something specifically that you had trouble with in 1.3.2 or in 1.4? I'd like to know, so I can keep an eye on those issues, and/or add them to the docs if they cause problems.
