Nova64 v0.4.9

Released: 2026-04-29

A very large release (270 commits) spanning the v0.3.x/v0.4.x line into trunk. Two headline efforts land here: the native Godot host merges to trunk, and the Babylon.js backend reaches broad parity with Three.js. This release also introduces the grouped nova64.* namespace API that becomes the canonical cart-facing contract.

Highlights

Godot native host — merged to trunk 🎉

• The GDExtension (nova64-godot/gdextension/), QuickJS bridge, cart shim, conformance harness, and visual-parity tooling become part of the main build. Nova64 carts run end-to-end through a native Godot 4.x host.
• Carts running natively: minecraft-demo, f-zero-nova-3d, star-fox-nova-3d, space-harrier-3d, fps-demo-3d, plus the 00–10 conformance series.
• fps-demo-3d ships a Godot-side WAD start-screen map picker loading freedoom1.wad through nova64.wad.load().
• Native voxel work: full 22-function voxel API in the JS shim over a sparse-Map + heightmap model, 3-octave noise terrain, 8-biome classification, and MultiMesh-batched rendering out to 64×64 columns.

Babylon.js backend parity

• GPU instancing API, SolidParticleSystem-based particles, TSL procedural shader materials, advanced glitch shader, and voxel texture-atlas UV parity.
• Framebuffer64 support and right-handed coordinate system to match Three.js player controls and 2D framebuffer compositing.
• Native WebXR VR/AR + Cardboard fallback and MediaPipe hand/face/pose tracking.

nova64.* namespace API

• New grouped namespace (16 sub-namespaces) with destructuring collision guardrails; examples migrated off flat ESLint globals.

Other

• Environment-aware logging (dev/production modes).
• MagicaVoxel .vox format support in the OS9 Model Viewer.
• TSL Shader Pack Phase 1 — procedural material presets + single-shader viewer.
• Adapter contract stabilized (capabilities, command-buffer, conformance tests).
• Version history moved to CHANGELOG.md; Playwright test infrastructure added.
