Release Notes

sass/dart-sass (sass)

v1.84.0

Compare Source

• Allow newlines in whitespace in the indented syntax.

• Potentially breaking bug fix: Selectors with unmatched brackets now always
  produce a parser error. Previously, some edge cases like [foo#{"]:is(bar"}) {a: b} would compile without error, but this was an unintentional bug.

• Fix a bug in which various Color Level 4 functions weren't allowed in plain
  CSS.

• Fix the error message for @extend without a selector and possibly other
  parsing edge-cases in contexts that allow interpolation.

Embedded Host

• Fixed the implementation of the SassBoolean type to adhere to the spec,
  now using a class instead of an interface.
