When
zSolver.maxNewtonIterations is greater than 1, the dynamics were often under-damped. The dynamics are correctly damped now, which will result in some simulations appearing more damped than before. To recover similar results to previous versions, decrease
zSolver.stiffnessDamping and
zSolver.massDamping – possibly to the new default values: 0.001 and 0.0 respectively. This
