A. HISTORY OF THE SOFTWARE |
|
========================== |
|
|
|
Python was created in the early 1990s by Guido van Rossum at Stichting |
|
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands |
|
as a successor of a language called ABC. Guido remains Python's |
|
principal author, although it includes many contributions from others. |
|
|
|
In 1995, Guido continued his work on Python at the Corporation for |
|
National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) |
|
in Reston, Virginia where he released several versions of the |
|
software. |
|
|
|
In May 2000, Guido and the Python core development team moved to |
|
BeOpen.com to form the BeOpen PythonLabs team. In October of the same |
|
year, the PythonLabs team moved to Digital Creations, which became |
|
Zope Corporation. In 2001, the Python Software Foundation (PSF, see |
|
https://www.python.org/psf/) was formed, a non-profit organization |
|
created specifically to own Python-related Intellectual Property. |
|
Zope Corporation was 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. |
|
|
|
Release Derived Year Owner GPL- |
|
from compatible? (1) |
|
|
|
0.9.0 thru 1.2 1991-1995 CWI yes |
|
1.3 thru 1.5.2 1.2 1995-1999 CNRI yes |
|
1.6 1.5.2 2000 CNRI no |
|
2.0 1.6 2000 BeOpen.com no |
|
1.6.1 1.6 2001 CNRI yes (2) |
|
2.1 2.0+1.6.1 2001 PSF no |
|
2.0.1 2.0+1.6.1 2001 PSF yes |
|
2.1.1 2.1+2.0.1 2001 PSF yes |
|
2.1.2 2.1.1 2002 PSF yes |
|
2.1.3 2.1.2 2002 PSF yes |
|
2.2 and above 2.1.1 2001-now PSF yes |
|
|
|
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. |
