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.
