FYI, I did a compare of Python 3.2 LICENSE to the much earlier 2.0.1 AFTER removing the history information – so the compare started with the statement “TERMS AND CONDITIONS FOR ACCESSING OR OTHERWISE USING PYTHON”. 

The licenses are the same other than adding to the list of copyright years and changing the title “CWI PERMISSIONS STATEMENT AND DISCLAIMER” TO “CWI LICENSE AGREEMENT FOR PYTHON 0.9.0 THROUGH 1.2”.  I have attached the compare.

I also noticed that the license link for particular versions of the Python software don’t always match.  For instance the link http://www.python.org/download/releases/2.4.6/license/ links to a license titled 2.4.4 license.  Similarly the URL for 3.0.1 points to a license titled 2.6.1.  There are others.

Between versions 2.4.4 and 2.5 “Version 2” is added to the license.  But the changes continue to be limited to extensions of the copyright years.

I believe that the discrete licenses are:

-          CWI LICENSE AGREEMENT FOR PYTHON 0.9.0 THROUGH 1.2

-          CNRI LICENSE AGREEMENT FOR PYTHON 1.6.1

-          Python Version 1 (Covers Python after 1.6.1 and prior to 2.5)

-          Python Version 2 (Covers Python 2.5 and after)

Thanks,
