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. |
