30.1.1 Python versions

The current shipping version of Python is 2.3.4. Most Python-OEChem distributions are built to work with Python 2.3. Python supports binary compatibility between patch versions, but not between minor versions. In other words, PyOEChem built for Python 2.3.4 can be expected to work with Python 2.3.x, but not backward to Python 2.2.X or forward to Python 2.4.x.

On some platforms, Python 2.2 is the default, installed version and we provide OEChem builds for that. For all other platforms, only Python 2.3 is supported.
