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.
