(By minor, you mean the y in x.y.z?) On Windows, yes - the DLL name
changes, causing problems for old extensions. 

On Unix, not necessarily - atleast not in incompatible ways.  I think
the API didn't change between 1.6 and 2.0 (see Include/modsupport.h);
I'm not sure whether 2.3 will see an API change.
