Please help solve milestone issues release so we can make a final
release as soon as possible:
http://code.google.com/p/sympy/issues/list?q=milestone=Release0.6.5
In case you are wondering, there is no beta1 release because after
uploading that release, I realized that sympy.logic was not included in
the sources, so I corrected this and had to move on to beta2 ...

Many thanks for the release. All tests pass for me now. Yes, we need
to fix most of the issues above, so any help is appreciated. I'll be
working on them over the weekend.
