Hi,
I just released 0.6.4.beta1, you can download tar.gz and a windows
installer from:
http://code.google.com/p/sympy/downloads/list
It's a beta only, e.g. all tests should pass, but there are still a
few issues to be fixed:
http://code.google.com/p/sympy/issues/list?q=label:Milestone-Release0...
They either need a review, or a simple patch. Most important one is to
reduce the import time:

rename disabled -> !USE_PYTEST on utilities.pytest
define a variable PYTHON in the doc's Makefile that let's you
customize the default python interpreter

change the behaviour of the code, it just makes it more readable
Implement debug framework.
robustify a test on solvers that was failing on amd64
improve debugging of limits using the debugging framework
Refactor Rational._eval_power
Fix roots_quartic:
Use by default cubics and quartics formula on roots().
