Bugfixes Bug in statistical inefficiency computation where self.max_n_iterations wasn't being used was fixed (#577). Bug in estimated performance in realtime yaml file fixed by iterating through all MCMC moves (#578) Potential bug fixed by explicitly updating and broadcasting thermodynamic states in replicas, when used in an MPI (distributed) context. Issue #579 (#587). Bug in handling unsampled states in realtime/offline analysis fixed by using MultiStateSampler._unsampled_states to build the mbar estimate array. Issue #592 (#593) Enhancements DHFR test system does not require parmed as dependency, since OpenMM can now handle prmtop/inpcrd files. Issue #539 (#588). MultiStateSamplerAnalyzer now allows to manually specify n_equilibrium_iterations and statistical_inefficiency parameters. (#586)
