| \section{History of the software} |
| |
| Python was created in the early 1990s by Guido van Rossum at Stichting |
| Mathematisch Centrum (CWI, see \url{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 \url{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 \url{http://www.zope.com/}). In 2001, the Python |
| Software Foundation (PSF, see \url{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 |
| \url{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. |
| |
| \begin{tablev}{c|c|c|c|c}{textrm}{Release}{Derived from}{Year}{Owner}{GPL compatible?} |
| \linev{0.9.0 thru 1.2}{n/a}{1991-1995}{CWI}{yes} |
| \linev{1.3 thru 1.5.2}{1.2}{1995-1999}{CNRI}{yes} |
| \linev{1.6}{1.5.2}{2000}{CNRI}{no} |
| \linev{2.0}{1.6}{2000}{BeOpen.com}{no} |
| \linev{1.6.1}{1.6}{2001}{CNRI}{no} |
| \linev{2.1}{2.0+1.6.1}{2001}{PSF}{no} |
| \linev{2.0.1}{2.0+1.6.1}{2001}{PSF}{yes} |
| \linev{2.1.1}{2.1+2.0.1}{2001}{PSF}{yes} |
| \linev{2.2}{2.1.1}{2001}{PSF}{yes} |
| \linev{2.1.2}{2.1.1}{2002}{PSF}{yes} |
| \linev{2.1.3}{2.1.2}{2002}{PSF}{yes} |
| \linev{2.2.1}{2.2}{2002}{PSF}{yes} |
| \end{tablev} |
| |
| \note{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.} |
| |
| Thanks to the many outside volunteers who have worked under Guido's |
| direction to make these releases possible. |
