SymPy 0.6.4
4 Apr 2009
robust and fast (still pure Python) multivariate factorization
sympy works with pickle protocol 2 (thus works in ipython parallel)
./sympy test now uses our testing suite and it tests both regular tests and doctests
examples directory tidied up
more trigonometric simplifications
polynomial roots finding and factoring vastly improved
mpmath updated
many bugfixes (more than 200 patches since the last release)
