Release Notes

sass/dart-sass (sass)

### [`v1.77.4`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1774) [Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.3...1.77.4) ##### Embedded Sass - Support passing `Version` input for `fatalDeprecations` as string over embedded protocol. - Fix a bug in the JS Embedded Host where `Version` could be incorrectly accepted as input for `silenceDeprecations` and `futureDeprecations` in pure JS. ### [`v1.77.3`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1773) [Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.2...1.77.3) ##### Dart API - `Deprecation.duplicateVariableFlags` has been deprecated and replaced with `Deprecation.duplicateVarFlags` to make it consistent with the `duplicate-var-flags` name used on the command line and in the JS API.
