v0.5.0 Changes
January 09, 2019- SymPy introduced a backward incompatibility to differentiation Matrices in
SymPy 1.2, which remained in SymPy 1.3, see:
https://github.com/sympy/sympy/issues/14958. This breaks PyDy's System class,
see: https://github.com/pydy/pydy/issues/395. A fix is introduced to handle
all support versions of SymPy. [PR
