- **BREAKING**: Moved project to [oddbird/blend][repo] on GitHub,
  and [@oddbird/blend][pkg] on NPM.
- **BREAKING**: Remove over-complicated settings & output options for now.
  Focus on practical Sass conversion to and from CIE functions.
- **NEW**: `lch()` hue channel accepts any angle unit
  (e.g. `turn`, `rad`, `grad`, or `deg`)
- **NEW**: `lab($lab, $a)` returns an (sRGB) Sass color
- **NEW**: Inspect LCH/Lab values of a Sass color with
  - `lightness()`
  - `a()` and `b()`
  - `chroma()` and `hue()`
- **NEW**: `contrast()` selects the best contrast from a list
- **NEW**: Generate new colors based on relative LCH & Lab adjustments:
  - `set()` to replace a channel value
  - `adjust()` to add or subtract from a channel
  - `scale()` to scale fluidly towards one "end" of the channel range
- **NEW**: `from()` converts a Sass color to LCH
  in order to adjust CIE lightness, chroma, and hue --
  using a syntax roughly based on
  [CSS Colors Level 5 relative syntax][relative]
