Full Release Notes

## What's new in v0.3.1

### Slider control rewrite

Complete overhaul of the slider UI component:

- Drag interaction moved from track bar to label (more intuitive, Blender-style)
- Defaults to unbounded range — no more artificial min/max clamping
- Arrow keys (Up/Down/Left/Right) for fine adjustments, Shift for 10× steps, Cmd/Ctrl for 0.1× precision
- Scroll wheel support on the label area
- Cleaner, more compact design

### ESC key fix

Fixed a long-standing annoyance where pressing Escape during a mid-action (drawing a wall, placing a slab, etc.) would both cancel the current action **and** switch back to select mode. Now:

- First ESC cancels the in-progress action (e.g., clears the wall draft)
- Second ESC switches back to select mode

Affected tools: Wall, Slab, Ceiling, Roof.

### STL and OBJ export

New export formats alongside the existing GLB export. Uses Three.js built-in exporters, no new dependencies.

- **STL** — standard for 3D printing (physical scale models)
- **OBJ** — widely used in rendering pipelines

Three format-specific buttons in the settings panel replace the single export button.

### State management fixes

- Fixed recursive `deleteNodesAction` that could cause state inconsistencies — now collects all descendants first, deletes in a single batch
- Fixed memory leak in temporal tracking (`prevNodesSnapshot` persisted across store re-creations)
- Fixed `requestAnimationFrame` in `updateNodesAction` without cleanup — could queue duplicate callbacks
- Removed unused debug variable in wall system

### Other improvements

- **Ghost wall fix** — `WALL_MIN_LENGTH` increased to match grid snap step (0.5m), preventing zero-length wall artifacts that crashed on reload
- **Antialias** — re-enabled default antialias on WebGPU renderer
- **Post-processing** — cleaned up pipeline code, improved error handling
- **Window panel** — removed artificial slider bounds on position, dimension, and frame controls
- **Resize handling** — added 100ms debounce for smoother viewport resizing
- **Community setup** — added issue/PR templates, CONTRIBUTING.md, simplified SETUP.md
