Guido remains Python’s principal author, although it includes many contributions from others.</p> <p>In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see <a class="reference external" href="https://www.cnri.reston.va.us/">https://www.cnri.reston.va.us/</a>) in Reston, Virginia where he released several versions of the software.</p> <p>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 <a class="reference external" href="http://www.zope.com/">http://www.zope.com/</a>). In 2001, the Python Software Foundation (PSF, see <a class="reference external" href="https://www.python.org/psf/">https://www.python.org/psf/</a>) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation is a sponsoring member of the PSF.</p> <p>All Python releases are Open Source (see <a class="reference external" href="https://opensource.org/">https://opensource.org/</a> for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases.</p> <table border="1" class="docutils"> <colgroup> <col width="23%" /> <col width="20%" /> <col width="17%" /> <col width="17%" /> <col width="24%" /> </colgroup> <thead valign="bottom"> <tr class="row-odd"><th class="head">Release</th> <th class="head">Derived from</th> <th class="head">Year</th> <th class="head">Owner</th> <th class="head">GPL compatible?</th> </tr> </thead> <tbody valign="top"> <tr class="row-even"><td>0.9.0 thru 1.2</td> <td>n/a</td> <td>1991-1995</td> <td>CWI</td> <td>yes</td> </tr> <tr class="row-odd"><td>1.3 thru 1.5.2</td> <td>1.2</td> <td>1995-1999</td> <td>CNRI</td> <td>yes</td> </tr> <tr class="row-even"><td>1.6</td> <td>1.5.2</td> <td>2000</td> <td>CNRI</td> <td>no</td> </tr> <tr class="row-odd"><td>2.0</td> <td>1.6</td> <td>2000</td> <td>BeOpen.com</td> <td>no</td> </tr> <tr class="row-even"><td>1.6.1</td> <td>1.6</td> <td>2001</td> <td>CNRI</td> <td>no</td> </tr> <tr class="row-odd"><td>2.1</td> <td>2.0+1.6.1</td> <td>2001</td> <td>PSF</td> <td>no</td> </tr> <tr class="row-even"><td>2.0.1</td> <td>2.0+1.6.1</td> <td>2001</td> <td>PSF</td> <td>yes</td> </tr> <tr class="row-odd"><td>2.1.1</td> <td>2.1+2.0.1</td> <td>2001</td> <td>PSF</td> <td>yes</td> </tr> <tr class="row-even"><td>2.1.2</td> <td>2.1.1</td> <td>2002</td> <td>PSF</td> <td>yes</td> </tr> <tr class="row-odd"><td>2.1.3</td> <td>2.1.2</td> <td>2002</td> <td>PSF</td> <td>yes</td> </tr> <tr class="row-even"><td>2.2 and above</td> <td>2.1.1</td> <td>2001-now</td> <td>PSF</td> <td>yes</td> </tr> </tbody> </table> <div class="admonition note"> <p class="first admonition-title">Note</p> <p class="last">GPL-compatible doesn’t mean that we’re distributing Python under the GPL.
