To install Sass 1.32.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Deprecate passing non-% numbers as lightness and saturation to hsl(), hsla(), color.adjust(), and color.change(). This matches the CSS specification, which also requires % for all lightness and saturation parameters. See [the Sass website][color-units] for more details.

• Deprecate passing numbers with units other than deg as the hue to hsl(), hsla(), adjust-hue(), color.adjust(), and color.change(). Unitless numbers are still allowed here, since they're allowed by CSS. See [the Sass website][color-units] for more details.

• Improve error messages about incompatible units.

• Properly mark some warnings emitted by sass:color functions as deprecation warnings.

Dart API

• Rename SassNumber.valueInUnits() to SassNumber.coerceValue(). The old name remains, but is now deprecated.

• Rename SassNumber.coerceValueToUnit(), a shorthand for SassNumber.coerceValue() that takes a single numerator unit.

• Add SassNumber.coerceToMatch() and SassNumber.coerceValueToMatch(), which work like SassNumber.coerce() and SassNumber.coerceValue() but take a SassNumber whose units should be matched rather than taking the units explicitly. These generate better error messages than SassNumber.coerce() and SassNumber.coerceValue().

• Add SassNumber.convertToMatch() and SassNumber.convertValueToMatch(), which work like SassNumber.coerceToMatch() and SassNumber.coerceValueToMatch() except they throw exceptions when converting unitless values to or from units.

• Add SassNumber.compatibleWithUnit(), which returns whether the number can be coerced to a single numerator unit.
