Very high-level response: it's not as bad as it seems.
Python is in fact quite conservative, and, as a commer-
cial developer, I can tell you the compatibility between
versions is satisfying.
There *are* issues with extensions, many of which are
tied to specific releases of Python. A couple of us
will probably follow-up with details.
My summary, though, is: yes, while there are issues
with version compatibility, they're roughly comparable
to those experienced in the Java world.
