### Release Notes

<details>
<summary>sass/dart-sass (sass)</summary>

###
[`v1.84.0`](https://redirect.github.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1840)

[Compare
Source](https://redirect.github.com/sass/dart-sass/compare/1.83.4...1.84.0)

-   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.
