Changes

• 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.
