- **NEW**: Expose access to `srgb-linear` color space. This is mainly for development and testing and not listed in docs currently.
- **FIX**: Cylindrical spaces, when calling `overlay` can now request to be overlaid in a different space. This is because alpha composition does not work well in cylindrical spaces. HSL, HSV, and HWB will now request `overlay` to be done in sRGB, and LCH will request overlay to be done in LAB.
- **FIX**: Add support for premultiplied alpha when interpolating via `premultiplied` option.
