New Contributors

• @nbrewerh made their first contribution in https://github.com/nasa/trick/pull/1547
• @Andyj4586 made their first contribution in https://github.com/nasa/trick/pull/1541

Full Changelog: https://github.com/nasa/trick/compare/19.6.0...19.7.0

• Support for LLVM/clang 15
• Support for Python 3.11
• Add new MonteCarloGenerate capability from EG CML
  • For more information, see the documentation on Monte Carlo Generate
• Significant TrickOps enhancements
  • For more information, see the documentation on TrickOps
• New example sims - SIM_aircraft and SIM_robot
• Add input file command to terminate a sim if a Python event errors out: trick.terminate_on_event_parse_error(<True|False>)
  • For more information, see input file documentation
• Add a command line flag to S_main to move all runtime file changes into the output directory, allowing for a read only sim directory: --read-only-sim
  • For more information, see documentation on Running A Simulation
• Add a compilation flag to allow ICG to parse to a specific C++ standard TRICK_ICGFLAGS += -icg-std=c++11
  • For more information, see documentation on Making a Simulation
• Add a make spotless target at the root makefile. This is recommended before building the upgraded version of Trick.
• Improved testing
• Various stability improvements and bugfixes
• Documentation improvements (thanks to @Codym48 and @garshaam for their contributions!)

• Hotfix for #1409 - patch variable server error when sending a value with units

• New variable server command: var_send_once
• Interface change: differentiate turning on/off sim objects from turning on/off jobs within sim objects.
  • set_sim_object_onoff: Command to turn on/off the sim_object. If sim object is disabled then enabled, jobs retain their status from before.
  • set_sim_object_jobs_onoff: Command to turn all the individual jobs on/off. Does not set overall sim object status. (old behavior of set_sim_object_onoff)
  • get_sim_object_onoff: Command to get sim object on/off status. 1 for on, 0 for off, -1 if object not found.
  • Sim object functions enable and disable are unchanged, but adds deprecation message to prefer enable_all_jobs and disable_all_jobs
• Improve testing and documentation for STL checkpointing
• Migrate integration testing to TrickOps
• Added test coverage metrics
• Fixed bug in Memory Manager coordinating destructor and deletion
• Fix Executive::set_time_tic_value segmentation fault
• Refactoring of autoconf.ac script
• Fix race condition in Monte Carlo Timeouts (thanks @irowebbn !)
• Improved documentation
• 32 bit support and better install instructions for RHEL 8
• Various stability improvements and minor bugfixes

• Improved documentation and Install Guide
• Improved tutorial (Thank you open source community + interns!)
• Web server improvements in freeze mode
• Major memory and stability improvements for RHEL 8, Ubuntu 18.04-22.04, and macOS Monterrey
• Major bugfixes for LLVM versions 10, 11, 12, 13, and 14.
• Migrate testing from centOS 8 to rockylinux, almalinux, Oracle Linux 8.
• Better support for Python 3
• Improved interpolator documentation
• New example sims:
  • SIM_splashdown represents a capsule splashing into a body of water, complete with a new 3D module viewer.
  • SIM_billiards is an interactive billiards simulation
• Improved SIM_balloon graphics
• Experimental support for macOS Silicon (M1, M2)

Various bug fixes, performance upgrades, and preview features.

Trick embedded webserver overhaul preview included. Will be detailed in next major release.

Trick 23 coming soon!

New Tool: Introducing TrickOps - An Extensible Sim Testing Framework

Features:

• Multiple simultaneous sim builds, runs, file vs. file comparisons, arbitrary post-run analyses, valgrind of runs
• Real-time progress bars for sim builds and runs
• Exit code management lets users easily define success & failure
• Failed comparisons can optionally generate koviz error reports
