I would *hope* that anyone publishing software on the web would know
which version they are developing on.  Then a simple statement "This
software was developed and tested only on Python 2.1.3."  would give
the prospective user some clue about the level of difficulty he faces.

Nope, you are free to choose the level of compatibility that you're
willing to provide.  But some indication of the level you choose would
be very helpful.
