That's not windows specific - most packages which distribute binary
packages need to package binaries for every minor version (2.4, 2.5,
etc...). That's certainly the case for numpy and scipy. Python does
not have a stable ABI across minor releases, only micro releases.

I doubt that's what Paul was referring to, though - he seemed more
concern with API/language changes than ABI issues.
