### 3.0.0

- 🎉 NEW: Add support for modern CSS color spaces. This means you can now export and parse CSS colors in `lab()`, `lch()`, `oklab()`, `oklch()` space.
- 🎉 NEW: you can now control the standard white reference point for the CIE Lab and CIE Lch color spaces via `setLabWhitePoint`.
- Breaking: `color.css()` will no longer return [legacy CSS colors](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/rgb#legacy_syntax_comma-separated_values) like `rgb(255, 255, 0)` but use modern CSS colors like `rgb(255 255 0)` instead.
- fix: you can now use chroma.js both via the default export as well as named exports in ES6.
- fix: switch to W3C implementation of OKLab color space

### 2.6.0

- 🎉 NEW: add [`color.shade()`](#color-shade), [`color.tint()`](#color-shade).
- fix: remove false w3c color cornflower

### 2.5.0

- refactored code base to ES6 modules

### 2.4.0

- add support for Oklab and Oklch color spaces

### 2.3.0

- use binom of degree n in chroma.bezier

### 2.2.0

- use Delta e2000 for chroma.deltaE #269

### 2.0.3

- hsl2rgb will, like other x2rgb conversions now set the default alpha to 1

### 2.0.2

- use a more mangle-safe check for Color class constructor to fix issues with uglifyjs and terser

### 2.0.1

- added `chroma.valid()` for checking if a color can be parsed by chroma.js

### 2.0.0

- chroma.js has been ported from CoffeeScript to ES6! This means you can now import parts of chroma in your projects!
- changed HCG input space from [0..360,0..100,0..100] to [0..360,0..1,0..1] (to be in line with HSL)
- added new object unpacking (e.g. `hsl2rgb({h,s,l})`)
- changed default interpolation to `lrgb` in mix/interpolate and average.
- if colors can't be parsed correctly, chroma will now throw Errors instead of silently failing with console.errors

### 1.4.1

- chroma.scale() now interprets `null` as NaN and returns the fallback color. Before it had interpreted `null` as `0`
- added `scale.nodata()` to allow customizing the previously hard-coded fallback (aka "no data") color #cccccc

### 1.4.0

- color.hex() now automatically sets the mode to 'rgba' if the colors alpha channel is < 1. so `chroma('rgba(255,0,0,.5)').hex()` will now return `"#ff000080"` instead of `"#ff0000"`. if this is not what you want, you must explicitly set the mode to `rgb` using `.hex("rgb")`.
- bugfix in chroma.average in LRGB mode ([#187](https://github.com/gka/chroma.js/issues/187))
- chroma.scale now also works with just one color ([#180](https://github.com/gka/chroma.js/issues/180))

### 1.3.5

- added LRGB interpolation

### 1.3.4

- passing _null_ as mode in scale.colors will return chroma objects

- added [chroma.deltaE](https://gka.github.io/chroma.js/#chroma-deltae)
- [color.set](https://gka.github.io/chroma.js/#color-set) now returns a new chroma instance
- chroma.scale now allows [disabling of internal cache](https://gka.github.io/chroma.js/#scale-cache)
