1.2 Python versions

Python-OEChem distributions are built to work with the latest version of Python at the time of release, i.e., this release supports Python 2.5. However, to allow for easier installation a default system Python is also supported if it is Python 2.3 or higher. On systems where Python 2.2 is still the default, we build for Python 2.5 using the system compiler. Other versions may also be made available for user convenience.

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.
