Color-0.3.0: CHANGELOG.md

# Changelog for Color

## 0.3.0

* Rename `Y` color model into `X` to avoid the annoying name conflict.
* Add `ColorSpace` instance for `Y'` and enrich it with base space info
* Rename `YCbCr` -> `Y'CbCr` and remove explicit linearity from its base space
* Fix BT470 transfer function. `ecctf` and `dcctf` were mixed up.
* Move `transfer` and `itransfer` functions into the `RedGreenBlue` class
* Move out `ecctf` and `dcctf` functions outside of `RedGreenBlue` class
* Remove all customized functions from RGB modules in favor of their respective class
  implementations:

  * `primaries` (standalone) -> `gamut` (in class)
  * `transfer` (standalone) -> `transfer` (in class)
  * `itransfer` (standalone) -> `itransfer` (in class)
  * `npmStandard` (standalone) -> `npm` (in class)
  * `inpmStandard` (standalone) -> `inpm` (in class)

* Addition of `coerceGamut`
* Fix re-export of vector's `MVector`, `Vector` type families.
* Re-arrange how modules are exported a little bit.

## 0.2.0

* Addition of `CIE1931 RGB` color space
* Add `Linearity` kind to `RedGreenBlue` color spaces.

* Addition of universal division `(//)` to `Elevator`
* Addition of CIE1931 RGB color space.
* Fix show instance for floating point colors: adjust formatting in Elevator for `Float` and `Double`
* Add record accessor functions: `chromaticityCIExyY`, `whitePointChromaticity`
* Fix show instance for `Gamut`
* Remove deprecated: `CIECAM02` and `ciecam02Adaptation`
