Am I correct in understanding that changing the Python minor revision number (2.5 -> 2.6) requires external modules to recompile? (It certainly does on Windows.)

There is an ongoing debate on that. The original intent was that you normally shouldn't have to recompile modules just because the Python version changes. Instead, you should do so when PYTHON_API_VERSION changes. Of course, such a change would also cause a change to PYTHON_API_VERSION. Then, even if PYTHON_API_VERSION changes, you aren't required to recompile your extension modules. Instead, you get a warning that the API version is different and might require recompilation: it does require recompilation if the extension module relies on some of the changed API. With this change, people not recompiling their extension modules would likely see Python crash rather quickly after seeing the warning about incompatible APIs.
