Release Notes

sass/dart-sass (sass)

v1.99.0

Compare Source

• Add support for parent selectors (&) at the root of the document. These are
  emitted as-is in the CSS output, where they're interpreted as the scoping
  root.

• User-defined functions named calc or clamp are no longer forbidden. If
  such a function exists without a namespace in the current module, it will be
  used instead of the built-in calc() or clamp() function.

• User-defined functions whose names begin with - and end with -expression,
  -url, -and, -or, or -not are no longer forbidden. These were
  originally intended to match vendor prefixes, but in practice no vendor
  prefixes for these functions ever existed in real browsers.

• User-defined functions named EXPRESSION, URL, and ELEMENT, those that
  begin with - and end with -ELEMENT, as well as the same names with some
  lowercase letters are now deprecated, These are names conflict with plain CSS
  functions that have special syntax.

  See the Sass website for details.

• In a future release, calls to functions whose names begin with - and end
  with -expression and -url will no longer have special parsing. For now,
  these calls are deprecated if their behavior will change in the future.

  See the Sass website for details.

• Calls to functions whose names begin with - and end with -progid:... are
  deprecated.

  See the Sass website for details.
