v3.0.2

ropesim 3.0.2 — 2026-07-08

Climbing rope physics engine — Python library, CLI, TUI, and a native 3D desktop app.

ropesim models lead-fall dynamics with a UIAA 101 / EN 892 impact-force model and
RK4 damped-spring integration in a Rust core (optional Rapier3D full-physics mode).
One engine, four frontends: a pip-installable Python library, a 20+ command CLI, a
Textual terminal UI, and a native C++ / Qt6 desktop application with a 60 fps OpenGL
rope renderer.

Changed

• CI no longer re-runs the full test matrix on version tags — a v* tag push

⚠️ ropesim informs judgement — it is for education and planning, never a substitute for testing, redundancy, and experience at the crag.
