Release Notes

sass/dart-sass (sass)

v1.79.5

Compare Source

• 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.

v1.79.4

Compare Source

JS API

• Fix a bug where passing green or blue to color.change() for legacy colors would fail.

v1.79.3

Compare Source

• Update the $channel parameter in the suggested replacement for color.red(), color.green(), color.blue(), color.hue(), color.saturation(), color.lightness(), color.whiteness(), and color.blackness() to use a quoted string.

v1.79.2

Compare Source

• Add a $space parameter to the suggested replacement for color.red(), color.green(), color.blue(), color.hue(), color.saturation(), color.lightness(), color.whiteness(), and color.blackness().

• Update deprecation warnings for the legacy JS API to include a link to relevant documentation.

v1.79.1

Compare Source

• No user-visible changes.

v1.79.0

Compare Source

• 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:

  • color.to-space($color, $space) converts $color to the given $space. In most cases this conversion is lossless—the color may end up out-of-gamut for the destination color space, but browsers will generally display it as best they can regardless. However, the hsl and hwb spaces can't represent out-of-gamut colors and so will be clamped.

  • color.channel($color, $channel, $space: null) returns the value of the given $channel in $color, after converting it to $space if necessary. It should be used instead of the old channel-specific functions such as color.red() and color.hue().

  • color.same($color1, $color2) returns whether two colors represent the same color even across color spaces. It differs from $color1 == $color2 because == never consider colors in different (non-legacy) spaces as equal.

  • color.is-in-gamut($color, $space: null) returns whether $color is in-gamut for its color space (or $space if it's passed).

  • color.to-gamut($color, $space: null) returns $color constrained to its space's gamut (or to $space's gamut, if passed). This is generally not recommended since even older browsers will display out-of-gamut colors as best they can, but it may be necessary in some cases.

  • color.space($color): Returns the name of $color's color space.

  • color.is-legacy($color): Returns whether $color is in a legacy color space (rgb, hsl, or hwb).

  • color.is-powerless($color, $channel, $space: null): Returns whether the given $channel of $color is powerless in $space (or its own color space). A channel is "powerless" if its value doesn't affect the way the color is displayed, such as hue for a color with 0 chroma.

  • color.is-missing($color, $channel): Returns whether $channel's value is missing in $color. Missing channels can be explicitly specified using the special value none and can appear automatically when color.to-space() returns a color with a powerless channel. Missing channels are usually treated as 0, except when interpolating between two colors and in color.mix() where they're treated as the same value as the other color.

• Update existing functions to support color spaces:

  • hsl() and color.hwb() no longer forbid out-of-bounds values. Instead, they follow the CSS spec by clamping them to within the allowed range.

  • color.change(), color.adjust(), and color.scale() now support all channels of all color spaces. However, if you want to modify a channel that's not in $color's own color space, you have to explicitly specify the space with the $space parameter. (For backwards-compatibility, this doesn't apply to legacy channels of legacy colors—for example, you can still adjust an rgb color's saturation without passing $space: hsl).

  • color.mix() and color.invert() now support the standard CSS algorithm for interpolating between two colors (the same one that's used for gradients and animations). To use this, pass the color space to use for interpolation to the $method parameter. For polar color spaces like hsl and oklch, this parameter also allows you to specify how hue interpolation is handled.

  • color.complement() now supports a $space parameter that indicates which color space should be used to take the complement.

  • color.grayscale() now operates in the oklch space for non-legacy colors.

  • color.ie-hex-str() now automatically converts its color to the rgb space and gamut-maps it so that it can continue to take colors from any color space.

• The following functions are now deprecated, and uses should be replaced with the new color-space-aware functions defined above:

  • The color.red(), color.green(), color.blue(), color.hue(), color.saturation(), color.lightness(), color.whiteness(), and color.blackness() functions, as well as their global counterparts, should be replaced with calls to color.channel().

  • The global adjust-hue(), saturate(), desaturate(), lighten(), darken(), transaprentize(), fade-out(), opacify(), and fade-in() functions should be replaced by color.adjust() or color.scale().

• Add a global-builtin future deprecation, which can be opted-into with the --future-deprecation flag or the futureDeprecations option in the JS or Dart API. This emits warnings when any global built-in functions that are now available in sass: modules are called. It will become active by default in an upcoming release alongside the @import deprecation.

Dart API

• Added a ColorSpace class which represents the various color spaces defined in the CSS spec.

• Added SassColor.space which returns a color's color space.

• Added SassColor.channels and .channelsOrNull which returns a list of channel values, with missing channels converted to 0 or exposed as null, respectively.

• Added SassColor.isLegacy, .isInGamut, .channel(), .isChannelMissing(), .isChannelPowerless(), .toSpace(), .toGamut(), .changeChannels(), and .interpolate() which do the same thing as the Sass functions of the corresponding names.

• SassColor.rgb() now allows out-of-bounds and non-integer arguments.

• SassColor.hsl() and .hwb() now allow out-of-bounds arguments.

• Added SassColor.hwb(), .srgb(), .srgbLinear(), .displayP3(), .a98Rgb(), .prophotoRgb(), .rec2020(), .xyzD50(), .xyzD65(), .lab(), .lch(), .oklab(), .oklch(), and .forSpace() constructors.

• Deprecated SassColor.red, .green, .blue, .hue, .saturation, .lightness, .whiteness, and .blackness in favor of SassColor.channel().

• Deprecated SassColor.changeRgb(), .changeHsl(), and .changeHwb() in favor of SassColor.changeChannels().

• Added SassNumber.convertValueToUnit() as a shorthand for SassNumber.convertValue() with a single numerator.

• Added InterpolationMethod and HueInterpolationMethod which collectively represent the method to use to interpolate two colors.

JS API

• While the legacy API has been deprecated since we released the modern API, we now emit warnings when the legacy API is used to make sure users are aware that it will be removed in Dart Sass 2.0.0. In the meantime, you can silence these warnings by passing legacy-js-api in silenceDeprecations when using the legacy API.

• Modify SassColor to accept a new space option, with support for all the new color spaces defined in Color Level 4.

• Add SassColor.space which returns a color's color space.

• Add SassColor.channels and .channelsOrNull which returns a list of channel values, with missing channels converted to 0 or exposed as null, respectively.

• Add SassColor.isLegacy, .isInGamut(), .channel(), .isChannelMissing(), .isChannelPowerless(), .toSpace(), .toGamut(), .change(), and .interpolate() which do the same thing as the Sass functions of the corresponding names.

• Deprecate SassColor.red, .green, .blue, .hue, .saturation, .lightness, .whiteness, and .blackness in favor of SassColor.channel().

Embedded Sass

• Add Color SassScript value, with support for all the new color spaces defined in Color Level 4.

• Remove RgbColor, HslColor and HwbColor SassScript values.

v1.78.0

Compare Source

• The meta.feature-exists function is now deprecated. This deprecation is named feature-exists.

• Fix a crash when using @at-root without any queries or children in the indented syntax.

JS API

• Backport the deprecation options (fatalDeprecations, futureDeprecations, and silenceDeprecations) to the legacy JS API. The legacy JS API is itself deprecated, and you should move off of it if possible, but this will allow users of bundlers and other tools that are still using the legacy API to still control deprecation warnings.

• Fix a bug where accessing SourceSpan.url would crash when a relative URL was passed to the Sass API.

Embedded Sass

• Explicitly expose a sass executable from the sass-embedded npm package. This was intended to be included in 1.63.0, but due to the way platform-specific dependency executables are installed it did not work as intended. Now users can run npx sass for local installs or just sass when sass-embedded is installed globally.

• Add linux-riscv64, linux-musl-riscv64, and android-riscv64 support for the sass-embedded npm package.

• Fix an edge case where the Dart VM could hang when shutting down when requests were in flight.

• Fix a race condition where the embedded host could fail to shut down if it was closed around the same time a new compilation was started.

• Fix a bug where parse-time deprecation warnings could not be controlled by the deprecation options in some circumstances.

v1.77.8

Compare Source

• No user-visible changes.

v1.77.7

Compare Source

• Declarations that appear after nested rules are deprecated, because the semantics Sass has historically used are different from the semantics specified by CSS. In the future, Sass will adopt the standard CSS semantics.

  See the Sass website for details.

• Potentially breaking bug fix: // in certain places such as unknown at-rule values was being preserved in the CSS output, leading to potentially invalid CSS. It's now properly parsed as a silent comment and omitted from the CSS output.

v1.77.6

Compare Source

• Fix a few cases where comments and occasionally even whitespace wasn't allowed between the end of Sass statements and the following semicolon.
