The Corporation for National Research Initiatives has released Python
1.6.1.  This is a "bugfix" release for Python 1.6, fixing the
GPL-incompatibility of the license.  The new 1.6.1 release can be
found here:

There is great subtlety to GPL compatibility.  I refer to the webpages
of the Free Software Foundation for an explanation, in particular

This change does not imply that Python 2.0 or later versions are now
compatible with the GPL.  Similar changes to their licenses need to be
made there; these are still under negotiation.  I'll keep you posted.
