Important: On macOS, if you are using a version older than mid-April 2026, you may need to re-install your certificate if you encounter errors! This is a one-time action — leaf certificates are now generated automatically for every new version and do not need to be re-installed manually. NEW PRC Server — completely redesigned web UI ("Control Deck"). The Babylon.js 3D viewport now fills the whole browser window and the controls float above it as glass panels: a top command bar (robot selector with status LED, icon navigation, license-status dot, light/dark theme toggle) and a transport dock with play/pause, loop, a scrubbable timeline, and per-axis ring-gauge telemetry. Ships with a new dark "cockpit" theme and a light theme; Radzen/Bootstrap dependencies were dropped in favor of a built-in design system. PRC Server — real robot geometry in the viewport. Robots that ship 3D geometry now render their actual link meshes instead of placeholder tubes; IMPROVEMENTS PRC Server — axis ring gauges now map to each robot's real joint limits (instead of a fixed ±360°), and any axis driven past its limit turns solid red (both the chip and the dial) for clear out-of-reach feedback. PRC Server — updated Babylon.js with smoother viewport interaction; removed unused rendering assets. PRC.Verify — clearer sign-in and licensing wording. BUG FIXES UR5e/7e — fixed an incorrect flange coordinate-system definition that mis-oriented the robot flange (and any attached tool/TCP). Grasshopper (GH & GH2) — swapping the robot in a PRC setup no longer leaves a stale "empty" robot behind on the server; the setup now keeps a stable ID across robot changes, the viewport rebuilds the geometry for the new robot, and the robot type is shown in the server top bar. PRC Server — fixed a theme error that could appear on page load from a stale browser cache.
