Trick Simulation Environment 25.0.0

New in Trick 25.0.0

• Jperf realtime performance analysis tool - Allows users to visualize realtime performance if frame logging was enabled during a simulation run. Located at bin/trick-jperf.
• Look and feel options for trick-tv
• enforcing cpp17 on Trick itself. Users can define any standard for their individual simulations builds.
• Updated documentation for best practices when attempting to run in hard realtime
• Support for llvm/clang 20/21 and gcc 11/13
• Added multi-rate integration and logging support
• New Trickify capability which expands upon previous version to compile normally static code into libraries for faster build iterations. Classic trickification still allowed.
• Enhanced Variable Server to support interaction with some STL container types: Vector, Array, and Deque. Supported element types listed in PR #1996. More STLs planned in future release. Allows viewing and updating of single-layer supported containers (so no vectors of vectors of vectors).
• Added ROS2-compliant example publisher/subscriber simulations using fastDDS protocol.
• Size checking via Variable Server on dynamically-allocated arrays and supported STL containers
• Including with release binary installers for RHEL8-flavored and Ubuntu-flavored OSs. Mac installer to come.
