Release Notes

sass/dart-sass

### [`v1.39.2`](https://togithub.com/sass/dart-sass/blob/master/CHANGELOG.md#​1392) [Compare Source](https://togithub.com/sass/dart-sass/compare/1.39.1...1.39.2) - Fix a bug where configuring with `@use ... with` would throw an error when that variable was defined in a module that also contained `@forward ... with`. ### [`v1.39.1`](https://togithub.com/sass/dart-sass/blob/master/CHANGELOG.md#​1391) [Compare Source](https://togithub.com/sass/dart-sass/compare/1.39.0...1.39.1) - Partial fix for a bug where `@at-root` does not work properly in nested imports that contain `@use` rules. If the only `@use` rules in the nested import are for built-in modules, `@at-root` should now work properly.
