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 (now Zope -Corporation, see http://www.zope.com). In 2001, the Python Software -Foundation (PSF, see http://www.python.org/psf/) was formed, a -non-profit organization created specifically to own Python-related -Intellectual Property. Zope Corporation is 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?

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. - - -B.
