  89. - Support for long-run average rewards on MDPs and Markov automata using a value-iteration based approach.
  90. - Storm can now check MDPs and Markov Automata (i.e. MinMax equation systems) via Linear Programming.
  91. - Parametric model checking is now handled in a separated library/executable called `storm-pars`.
  92. - Wellformedness constraints on PMCs:
  93. * include constraints from rewards
