The full notes for this version are its short notes: that was all that was written then.
- Fixed: whole surfaces (like the floor) sometimes disappeared.
- The renderer skips faces that are completely buried inside other blocks. It decided that from only 5 sample points, and corner columns plus something in the middle of the map could cover all 5. The entire floor was then treated as buried and not drawn.
- It now checks a 9×9 grid, so only faces that really are buried get skipped.
- Maps re-bake their lighting once.
