Guido van Rossum3225c1f2001-03-22 15:41:06 +00001A. HISTORY OF THE SOFTWARE
2==========================
Guido van Rossumea70b492000-09-01 19:51:14 +00003
4Python was created in the early 1990s by Guido van Rossum at Stichting
5Mathematisch Centrum (CWI) in the Netherlands as a successor of a
6language called ABC. Guido is Python's principal author, although it
Guido van Rossum028d0692000-09-03 03:13:44 +00007includes many contributions from others. The last version released
8from CWI was Python 1.2. In 1995, Guido continued his work on Python
9at the Corporation for National Research Initiatives (CNRI) in Reston,
Guido van Rossumea70b492000-09-01 19:51:14 +000010Virginia where he released several versions of the software. Python
111.6 was the last of the versions released by CNRI. In 2000, Guido and
Guido van Rossum9d644792000-12-12 15:24:57 +000012the Python core development team moved to BeOpen.com to form the
Guido van Rossum3225c1f2001-03-22 15:41:06 +000013BeOpen PythonLabs team. Python 2.0 was the first and only release
14from BeOpen.com.
15
16Following the release of Python 1.6, and after Guido van Rossum left
17CNRI to work with commercial software developers, it became clear that
18the ability to use Python with software available under the GNU Public
19License (GPL) was very desirable. CNRI and the Free Software
Thomas Woutersf5db48e2001-03-22 16:03:53 +000020Foundation (FSF) interacted to develop enabling wording changes to the
Guido van Rossum3225c1f2001-03-22 15:41:06 +000021Python license. Python 1.6.1 is essentially the same as Python 1.6,
22with a few minor bug fixes, and with a GPL compatible open source
23license. Python 2.1 is a derivative work of Python 1.6.1, as well as
24of Python 2.0.

Guido van Rossum71500c82001-01-18 14:39:49 +000026After Python 2.0 was released by BeOpen.com, Guido van Rossum and the
Guido van Rossum3225c1f2001-03-22 15:41:06 +000027other PythonLabs developers joined Digital Creations. All
28intellectual property added from this point on, starting with Python
292.1 and its alpha and beta releases, is owned by the Python Software
30Foundation (PSF), a non-profit modeled after the Apache Software
31Foundation. See http://www.python.org/psf/ for more information about
32the PSF.

34Thanks to the many outside volunteers who have worked under Guido's
35direction to make these releases possible.
