To install Sass 1.79.5, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Changes to how selector.unify() and @extend combine selectors:

  • The relative order of pseudo-classes (like :hover) and pseudo-elements (like ::before) within each original selector is now preserved when they're combined.

  • Pseudo selectors are now consistently placed at the end of the combined selector, regardless of which selector they came from. Previously, this reordering only applied to pseudo-selectors in the second selector.

• Tweak the color transformation matrices for OKLab and OKLCH to match the newer, more accurate values in the CSS spec.

• Fix a slight inaccuracy case when converting to srgb-linear and display-p3.

• Potentially breaking bug fix: math.unit() now wraps multiple denominator units in parentheses. For example, px/(em*em) instead of px/em*em.

Command-Line Interface

• Use @parcel/watcher to watch the filesystem when running from JavaScript and not using --poll. This should mitigate more frequent failures users have been seeing since version 4.0.0 of Chokidar, our previous watching tool, was released.

JS API

• Fix SassColor.interpolate() to allow an undefined options parameter, as the types indicate.

Embedded Sass

• Properly pass missing color channel values to and from custom functions.
