I was under the impression that binary compatibility was only guaranteed within a minor revision (e.g., 2.6.1 must run code compiled for 2.6.0, but 2.7.0 doesn't have to).  I've been wrong before, though.

Certainly the C extension module I maintain is sprinkled with #ifdef's so it will compile under 2.5, 2.6, and 3.0. ;-)
