Binary compatibility across Python versions?

[Philip Semanchuk]

Hi all,
Does Python guarantee binary compatibility across major, minor and/or  
micro versions? I looked through the docs and even with Google's help  
I wasn't able to find any official statements on this subject.


Specifically, I'm concerned with binaries created by SWIG for a C++  
library that our project uses. We'd like to ship precompiled binaries  
for Linux, OS X and Windows for Python 2.5 and 2.6. I'm hoping that it  
is sufficient to create binaries for each Python for each platform (3  
* 2 == 6 total precompiled binaries).

Thanks for any advice and pointers to official documentation on the  
subject.

Cheers
Philip
