We only provide shared libraries that are to be loaded by the Python runtime. So those shared libraries are just Python module and their being written in C++ is an implementation detail. What matters is therefore only the Python API, in which I include the Python API exposed by our *.so, on the one hand and the C++ API on the other hand. But then each cctbx release contains a TAG file providing a version number the set of which is sortable, e.g. 2012_05_08_2305
