| 13 | +This minor upgrade adds some fixes and changes that are a bit more than just patches. The text now |
| 14 | +has subchapter headings to help readers browse content and get a bit more context. We're introducing |
| 15 | +new type aliases `point3` and `color` for `vec3` to better indicate the underlying mathematical |
| 16 | +types of parameters and variables. Overall, a bunch of small improvements that we'd recommend |
| 17 | +adopting, but may warrant comparison with any current projects. |
