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.
