The lead paragraph and Graphics section already mentioned 3D mesh / multi-material / perspective projection, but two feature lists hadn't caught up with the 19.7 3D surface:

  • Camera — added the `Camera3d` perspective camera (drop-in 2D subclass with frustum culling), which was entirely absent from the Camera list despite being a headline 19.7 feature. Also noted the follow damping is now frame-rate-independent.
  • Physics — broad-phase now mentions the `Octree` (3D, auto-swapped from QuadTree on `sortOn` crossings); region queries now list sphere queries + 3D raycasts (`raycast3d`) alongside the existing raycast / AABB.

Docs-only, no code change.
