PySB v1.2.0 Released

New features

Brand new Simulator classes and SimulationResult classes in the pysb.simulator package. The old pysb.integrate API is unchanged but has been reimplemented using the Simulator class. Model import from other types of models in the pysb.importers package. Currently supports BNGL and SBML model import.


  • pysb_flat exporter now supports MatchOnce.
  • Some Python 2 Unicode issues were addressed by eliminating uses of type(...) == str.
