What's new

v2.0.3Nov 3, 2026

🎮 NIBBLY 2.0.3 — BUG FIXES & FLOWCHART QoL
A focused patch release fixing six reported bugs and improving Flowcharts usability.
📐 FLOWCHARTS QoL ✔️ New "Edit" mode — one tap on a node opens the editor ✔️ Nibbly-style modals replace prompt() and confirm() (iOS-friendly) ✔️ Camera no longer recenters on add/connect/delete/move — your scroll position is preserved ✔️ Arrows now stick exactly to diamonds, ellipses and parallelograms ✔️ Exported SVG/PNG wrap title and subtitles inside the node
🎨 UI FIXES ✔️ Formula buttons: icons now always inline to the left of the text (no :has() dependency, works on old WebViews) ✔️ Loading screen background now turns red on error (not just the accent) ✔️ "Process" node now correctly labeled "Proceso" in Spanish
🔧 UNDER THE HOOD ✔️ Shape-aware edgePoint() for all node types ✔️ Global pointer listeners registered once — no more duplicate handlers per render ✔️ Flowcharts internal version → 2.3.0
🛡️ NO AI ONLINE OR LOCAL Everything runs locally. No telemetry. No training.
✅ Official Release — v2.0.3
