v1.87.0

Compare Source

• Potentially breaking bug fix: When a plain CSS file with a top-level
  nesting selector & is loaded into a nested Sass context via
  meta.load-css() or @import, Sass now emits plain CSS nesting rather than
  incorrectly combining it with the parent selector using a descendant
  combinator.

v1.86.3

Compare Source

• Fix a bug introduced in 1.86.1 where Sass fails to resolve paths starting with
  a .. segment.

v1.86.2

Compare Source

• No user-visible changes.

v1.86.1

Compare Source

• Improve the performance of file: URL case canonicalization on Windows and
  Mac OS.

v1.86.0

Compare Source

• Add support for % as an expression in its own right. It will still be parsed
  as the modulo operator when between two other expressions, but in any other
  context it will be an expression whose value is the unquoted string %.

• Consider attr() to be a special number function that can be used as a
  channel in color functions.

• Deprecate user-defined functions named type() so that we can eventually
  support the new CSS type() function.

Dart API

• Increase the minimum Dart SDK to 3.6.0.

v1.85.1

Compare Source

• Fix a bug where global Sass functions whose names overlap with CSS math
  functions could incorrectly be treated as CSS math functions even though they
  used Sass-only features, causing compilation failures. For example,
  round(-$var / 2) previously threw an error but now works as intended.

v1.85.0

Compare Source

• No longer fully trim redundant selectors generated by @extend. This caused
  unacceptable performance issues for certain heavy users of @extend. We'll
  try to find a more performant way to accomplish it in the future.

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.
