Great job. I pushed in one small patch with docstrings fxies (Aaron
reviewed) and I suggest we also update the sympy logo:
http://code.google.com/p/sympy/issues/detail?id=1506
Also so that I don't forget, I need to:
* test on windows
* test in Sage
* test the deb package in debian
I'll try to do so tomorrow and let's release on Monday.

Ok, I didn't manage to do that yesterday, so I am doing it right now.

Works on windows 7 in python 2.6 and all tests pass.

I am testing now.

works, except some failures in the plotting code in my Debian chroot:

One test fails, see:
http://code.google.com/p/sympy/issues/detail?id=1536
I have attached a fix to that issue. Fabian, please apply and if all
is ok, make a release.
The sympy.doctest() fail a lot in Sage, probably due to Sage using
some different printer or something. But all regular tests work, so
that's the most important.

Tomorrow I'll review all carefully and make a final release :-)

Thanks. You forgot to push this in:
http://code.google.com/p/sympy/issues/detail?id=1414
I did that now.
