BeOpen.com to form the BeOpen PythonLabs team.  In October of the same 
year, the PythonLabs team moved to Digital Creations (now Zope 
Corporation, see http://www.zope.com).  In 2001, the Python Software 
Foundation (PSF, see http://www.python.org/psf/) was formed, a 
non-profit organization created specifically to own Python-related 
Intellectual Property.  Zope Corporation is a sponsoring member of 
the PSF. 
 
All Python releases are Open Source (see http://www.opensource.org for 
the Open Source Definition).  Historically, most, but not all, Python 
releases have also been GPL-compatible; the table below summarizes 
the various releases.

Footnotes: 
 
(1) GPL-compatible doesn't mean that we're distributing Python under 
    the GPL.  All Python licenses, unlike the GPL, let you distribute 
    a modified version without making your changes open source.  The 
    GPL-compatible licenses make it possible to combine Python with 
    other software that is released under the GPL; the others don't. 
 
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, 
    because its license has a choice of law clause.  According to 
    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 
    is "not incompatible" with the GPL. 
 
Thanks to the many outside volunteers who have worked under Guido's 
direction to make these releases possible.
