====== - depend on package ``sym`` for symbolic backend
0.5.3
====== - minor fixes
0.5.2
====== - from_callback now respects backend paramter (e.g. ``math`` or ``sympy``)
0.5.1
====== - Added SymbolicSys.analytic_stiffness - Allow chaining pre-/post-processors in TransformedSys - Make PartiallySolvedSys more general (allow use dependent variable) - Better choice of first_step when not specified (still arbitrary though) - Documentation fixes - SymbolicSys got a new classmethod: from_other
0.5.0
====== - OdeSys.solve() changed signature: first arg "solver" moved to kwargs and renamed "integrator". Default of None assumed (inspects $PYODESYS_INTEGRATOR) - OdeSys.integrate_* renamed ``_integrate_*`` (only for internal use). - Info dict from integrate() keys renamed (for consistency with pyneqsys): - nrhs -> nfev - njac -> njev - internal_xout (new) - internal_yout (new)
0.4.0
====== - SymbolicSys not available directly from pyodesys (but from pyodesys.symbolic) - OdeSys.integrate_* documented as private (internal). - symbolic.PartiallySolvedSystem added - multiple (chained) pre and postprocessors supported - stiffness may be inspected retroactively (ratio biggest/smallest eigenvalue of the jacobian matrix).
