1 | A. HISTORY OF THE SOFTWARE |
---|
2 | ========================== |
---|
3 | |
---|
4 | Python was created in the early 1990s by Guido van Rossum at Stichting |
---|
5 | Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands |
---|
6 | as a successor of a language called ABC. Guido remains Python's |
---|
7 | principal author, although it includes many contributions from others. |
---|
8 | |
---|
9 | In 1995, Guido continued his work on Python at the Corporation for |
---|
10 | National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) |
---|
11 | in Reston, Virginia where he released several versions of the |
---|
12 | software. |
---|
13 | |
---|
14 | In May 2000, Guido and the Python core development team moved to |
---|
15 | BeOpen.com to form the BeOpen PythonLabs team. In October of the same |
---|
16 | year, the PythonLabs team moved to Digital Creations (now Zope |
---|
17 | Corporation, see http://www.zope.com). In 2001, the Python Software |
---|
18 | Foundation (PSF, see http://www.python.org/psf/) was formed, a |
---|
19 | non-profit organization created specifically to own Python-related |
---|
20 | Intellectual Property. Zope Corporation is a sponsoring member of |
---|
21 | the PSF. |
---|
22 | |
---|
23 | All Python releases are Open Source (see http://www.opensource.org for |
---|
24 | the Open Source Definition). Historically, most, but not all, Python |
---|
25 | releases have also been GPL-compatible; the table below summarizes |
---|
26 | the various releases. |
---|
27 | |
---|
28 | Release Derived Year Owner GPL- |
---|
29 | from compatible? (1) |
---|
30 | |
---|
31 | 0.9.0 thru 1.2 1991-1995 CWI yes |
---|
32 | 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes |
---|
33 | 1.6 1.5.2 2000 CNRI no |

---|

---|
37 | 2.0.1 2.0+1.6.1 2001 PSF yes |
---|
38 | 2.1.1 2.1+2.0.1 2001 PSF yes |
---|
39 | 2.1.2 2.1.1 2002 PSF yes |
---|
40 | 2.1.3 2.1.2 2002 PSF yes |
---|
41 | 2.2 and above 2.1.1 2001-now PSF yes |
---|
42 | |
---|
43 | Footnotes: |
---|
44 | |
---|
45 | (1) GPL-compatible doesn't mean that we're distributing Python under |
---|
46 | the GPL. All Python licenses, unlike the GPL, let you distribute |
---|
47 | a modified version without making your changes open source. The |
---|
48 | GPL-compatible licenses make it possible to combine Python with |
---|
49 | other software that is released under the GPL; the others don't. |
---|
50 | |
---|
51 | (2) According to Richard Stallman, 1.6.1 is not GPL-compatible, |
---|
52 | because its license has a choice of law clause. According to |
---|
53 | CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 |
---|
54 | is "not incompatible" with the GPL. |
---|
55 | |
---|
56 | Thanks to the many outside volunteers who have worked under Guido's |
---|
57 | direction to make these releases possible. |
