v1.4.0

• Added support for multi-dimensional quantile queries.
• Added support for multi-objective model checking under pure (deterministic) schedulers with bounded memory using --purescheds.
• Allow to quickly check a benchmark from the Quantitative Verification Benchmark Set using the --qvbs option.
• Added script resources/examples/download_qvbs.sh to download the QVBS.
• If an option is unknown, Storm now suggests similar option names.
• Flagged several options as 'advanced' to clean up the --help-message. Use --help all to display a complete list of options.
• Support for parsing of exact time bounds for properties, e.g., P=? [F=27 "goal"].
• Export of optimal schedulers when checking MDPs with the sparse engine (experimental). Use --exportscheduler <filename>.
• PRISM language: Support for the new round operator.
• PRISM language: Improved error messages of the parser.
• JANI: Allow bounded types for constants.
• JANI: Support for non-trivial reward accumulations.
• JANI: Fixed support for reward expressions over non-transient variables.
• DRN: Added support for exact parsing and action-based rewards.
• DRN: Support for placeholder variables which allows to parse recurring rational functions only once.
• Fixed sparse bisimulation of MDPs (which failed if all non-absorbing states in the quotient are initial).
• Support for export of MTBDDs from Storm.
• Support for k-shortest path counterexamples (arguments -cex --cextype shortestpath)
• New settings module transformation for Markov chain transformations. Use --help transformation to get a list of available transformations.
• Support for eliminating chains of Non-Markovian states in MAs via --eliminate-chains.
• Export to dot format allows for maximal line width in states (argument --dot-maxwidth <width>)
• storm-conv can now apply transformations on a prism file.
• storm-pars: Enabled building, bisimulation and analysis of symbolic models.
• storm-dft: Support partial-order for state space generation.
• storm-dft: Compute lower and upper bounds for number of BE failures via SMT.
• storm-dft: Allow to set relevant events which are not set to Don't Care.
• storm-dft: Support for constant failed BEs. Use flag --uniquefailedbe to create a unique constant failed BE.
• storm-dft: Support for probabilistic BEs via PDEPs.
• Fixed linking with Mathsat on macOS.
• Fixed linking with IntelTBB for GCC.
• Fixed compilation for macOS Mojave and higher.
• Several bug fixes.
