[Compare
Source](https://togithub.com/sass/dart-sass/compare/1.68.0...1.69.0)

- Add a `meta.get-mixin()` function that returns a mixin as a
first-class Sass
    value.

-   Add a `meta.apply()` mixin that includes a mixin value.

- Add a `meta.module-mixins()` function which returns a map from mixin
names in
    a module to the first-class mixins that belong to those names.

- Add a `meta.accepts-content()` function which returns whether or not a
mixin
    value can take a content block.

- Add support for the relative color syntax from CSS Color 5. This
syntax
cannot be used to create Sass color values. It is always emitted as-is
in the
    CSS output.

##### Dart API

- Deprecate `Deprecation.calcInterp` since it was never actually emitted
as a
    deprecation.

##### Embedded Sass

- Fix a rare race condition where the embedded compiler could freeze
when a
    protocol error was immediately followed by another request.
