- SimB simulation can be controlled by an external simulator, e. g. a reinforcement learning agent
- Decisions made by reinforcement learning agent can be corrected by a safety shield via a
SHIELD_INTERVENTIONdefinition - Added estimation of average and cumulative sum to SimB
- Added average trace length to SimB statistics
- Added CSV export of SimB statistics with trace length and estimated value
- Added column for number of steps to trace replay table
- Added syntax highlighting for a few more code text fields
- Editor now asks for confirmation before discarding unsaved changes when reloading the machine

VISB_JSON_FILEdefault - Fixed editor syntax highlighting sometimes not working on Windows
- Improved error messages when a machine file could not be read
- Improved handling of invalid values for ProB preferences
- Improved feedback for internal errors in VisB
Note: This is the last release to support Java 8, 11, and 17. The next release will require Java 21 or newer. This only affects users of the multi-platform jar - consider using the platform-specific binaries, which have an appropriate JRE version bundled.
Note: The multi-platform jar might not work on all macOS processor architectures - consider using the platform-specific binaries, which are available for both x86_64 and arm64.
