Changes

• In expanded mode, emit characters in Unicode private-use areas as escape sequences rather than literal characters.

• Fix a bug where quotes would be omitted for an attribute selector whose value was a single backslash.

• Properly consider numbers that begin with . as "plain CSS" for the purposes of parsing plain-CSS min() and max() functions.

• Allow if to be used as an unquoted string.

• Properly parse backslash escapes within url() expressions.

• Fix a couple bugs where @extends could be marked as unsatisfied when multiple identical @extends extended selectors across @use rules.

Command Line Interface

• Strip CRLF newlines from snippets of the original stylesheet that are included in the output when an error occurs.

JS API

• Don't crash when a Windows path is returned by a custom Node importer at the same time as file contents.

• Don't crash when an error occurs in a stylesheet loaded via a custom importer with a custom URL scheme.

Dart API
