   1 \section{History of the software}
   2
   3 Python was created in the early 1990s by Guido van Rossum at Stichting
   4 Mathematisch Centrum (CWI, see \url{http://www.cwi.nl/}) in the Netherlands
   5 as a successor of a language called ABC.  Guido remains Python's
   6 principal author, although it includes many contributions from others.
   7
   8 In 1995, Guido continued his work on Python at the Corporation for
   9 National Research Initiatives (CNRI, see \url{http://www.cnri.reston.va.us/})
  10 in Reston, Virginia where he released several versions of the
  11 software.
  12
  13 In May 2000, Guido and the Python core development team moved to
  14 BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
  15 year, the PythonLabs team moved to Digital Creations (see
  16 \url{http://www.digicool.com/}).  In 2001, the Python Software
  17 Foundation (PSF, see \url{http://www.python.org/psf/}) was formed, a
  18 non-profit organization created specifically to own Python-related
  19 Intellectual Property.  Digital Creations is a sponsoring member of
  20 the PSF.
  21
  22 All Python releases are Open Source (see
  23 \url{http://www.opensource.org/} for the Open Source Definition).
  24 Historically, most, but not all, Python releases have also been
  25 GPL-compatible; the table below summarizes the various releases.
  26
  27 \begin{tablev}{c|c|c|c|c}{textrm}{Release}{Derived from}{Year}{Owner}{GPL compatible?}
  28   \linev{0.9.0 thru 1.2}{n/a}{1991-1995}{CWI}{yes}
  29   \linev{1.3 thru 1.5.2}{1.2}{1995-1999}{CNRI}{yes}
  30   \linev{1.6}{1.5.2}{2000}{CNRI}{no}
  31   \linev{2.0}{1.6}{2000}{BeOpen.com}{no}
  32   \linev{1.6.1}{1.6}{2001}{CNRI}{no}
  33   \linev{2.1}{2.0+1.6.1}{2001}{PSF}{no}
  34   \linev{2.0.1}{2.0+1.6.1}{2001}{PSF}{yes}
  35   \linev{2.1.1}{2.1+2.0.1}{2001}{PSF}{yes}
  36   \linev{2.2}{2.1.1}{2001}{PSF}{yes}
  37 \end{tablev}
  38
  39 \note{GPL-compatible doesn't mean that we're distributing
  40 Python under the GPL.  All Python licenses, unlike the GPL, let you
  41 distribute a modified version without making your changes open source.
  42 The GPL-compatible licenses make it possible to combine Python with
  43 other software that is released under the GPL; the others don't.}
  44
  45 Thanks to the many outside volunteers who have worked under Guido's
  46 direction to make these releases possible.
