     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.

    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
    34     2.0             1.6         2000        BeOpen.com  no
    35     1.6.1           1.6         2001        CNRI        yes (2)
    36     2.1             2.0+1.6.1   2001        PSF         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.
