Changelog

This changelog lists only the most important changes. Smaller (bug)fixes as well as non-mature features are not part of the changelog. The releases of major and minor versions contain an overview of changes since the last major/minor update.

Version 1.1.x

Version 1.1.1

  • c++ api changes: Building model takes BuilderOptions instead of extended list of Booleans, does not depend on settings anymore.
  • storm-cli-utilities now contains cli related stuff, instead of storm-lib
  • storm-pars: support for welldefinedness constraints in mdps.

Version 1.1.0 (2017/8)

  • Support for long-run average rewards on MDPs and Markov automata using a value-iteration based approach.
  • Storm can now check MDPs and Markov Automata (i.e. MinMax equation systems) via Linear Programming.
  • Parametric model checking is now handled in a separated library/executable called storm-pars.
  • Wellformedness constraints on PMCs:
    • include constraints from rewards
    • are in smtlib2
    • fixed
    • computation of only constraints without doing model checking is now supported
  • Fix for nested formulae
  • JANI: Explicit engine supports custom model compositions.
  • Support for parsing/building models given in the explicit input format of IMCA.
  • Storm now overwrites files if asked to write files to a specific location.
  • Changes in build process to accommodate for changes in carl. Also, more robust against issues with carl.
  • USE_POPCNT removed in favor of FORCE_POPCNT. The popcnt instruction is used if available due to march=native, unless portable is set. Then, using FORCE_POPCNT enables the use of the SSE 4.2 instruction

Version 1.0.x

Version 1.0.1 (2017/4)

  • Multi-objective model checking support now fully included
  • Several improvements in parameter lifting
  • Several improvements in JANI parsing
  • Properties can contain model variables
  • Support for rational numbers/functions in decision diagrams via sylvan
  • Elimination-based solvers (exact solution) for models stored as decision diagrams
  • Export of version and configuration to cmake
  • Improved building process

Version 1.0.0 (2017/3)
