Guido is Python's principal author, although it -includes many contributions from others. The last version released -from CWI was Python 1.2. In 1995, Guido continued his work on Python -at the Corporation for National Research Initiatives (CNRI) in Reston, -Virginia where he released several versions of the software. Python -1.6 was the last of the versions released by CNRI. In 2000, Guido and -the Python core development team moved to BeOpen.com to form the -BeOpen PythonLabs team. Python 2.0 was the first and only release -from BeOpen.com. - -Following the release of Python 1.6, and after Guido van Rossum left -CNRI to work with commercial software developers, it became clear that -the ability to use Python with software available under the GNU Public -License (GPL) was very desirable. CNRI and the Free Software -Foundation (FSF) interacted to develop enabling wording changes to the -Python license. Python 1.6.1 is essentially the same as Python 1.6, -with a few minor bug fixes, and with a different license that enables -later versions to be GPL-compatible. Python 2.0.1 is a derivative work -of Python 1.6.1, as well as of Python 2.0. - -After Python 2.0 was released by BeOpen.com, Guido van Rossum and the -other PythonLabs developers joined Digital Creations.
