[Python-Dev] [RELEASED] Python 3.3.0

[Georg Brandl]

Thanks. It's really a team effort: a little digging in the hg history says
that:

* 86 people have committed during the 3.3 development
* 70 during 3.2 development and
* 55 during 3.1 development

No surprise the feature list is so long...

cheers,
Georg
