1.79.0

• Breaking change: Passing a number with unit % to the $alpha parameter of color.change(), color.adjust(), change-color(), and adjust-color() is now interpreted as a percentage, instead of ignoring the unit. For example, color.change(red, $alpha: 50%) now returns rgb(255 0 0 / 0.5).

• Potentially breaking compatibility fix: Sass no longer rounds RGB channels to the nearest integer. This means that, for example, rgb(0 0 1) != rgb(0 0 0.6). This matches the latest version of the CSS spec and browser behavior.

• Potentially breaking compatibility fix: Passing large positive or negative values to color.adjust() can now cause a color's channels to go outside that color's gamut. In most cases this will currently be clipped by the browser and end up showing the same color as before, but once browsers implement gamut mapping it may produce a different result.

• Add support for CSS Color Level 4 [color spaces]. Each color value now tracks its color space along with the values of each channel in that color space. There are two general principles to keep in mind when dealing with new color spaces:

  1. With the exception of legacy color spaces (rgb, hsl, and hwb), colors will always be emitted in the color space they were defined in unless they're explicitly converted.

  2. The color.to-space() function is the only way to convert a color to another color space. Some built-in functions may do operations in a different color space, but they'll always convert back to the original space afterwards.

• rgb colors can now have non-integer channels and channels outside the normal gamut of 0-255. These colors are always emitted using the rgb() syntax so that modern browsers that are being displayed on wide-gamut devices can display the most accurate color possible.

• Add support for all the new color syntax defined in Color Level 4, including:

  • oklab(), oklch(), lab(), and lch() functions;
  • a top-level hwb() function that matches the space-separated CSS syntax;
  • and a color() function that supports the srgb, srgb-linear, display-p3, a98-rgb, prophoto-rgb, rec2020, xyz, xyz-d50, and xyz-d65 color spaces.

• Add new functions for working with color spaces:
