[Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.5...1.77.6)

-   Fix a few cases where comments and occasionally even whitespace wasn't allowed
    between the end of Sass statements and the following semicolon.

### [`v1.77.5`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1775)

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.4...1.77.5)

[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.

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.1...1.77.2)

-   Don't emit deprecation warnings for functions and mixins beginning with `__`.

-   Allow user-defined functions whose names begin with `_` and otherwise look
    like vendor-prefixed functions with special CSS syntax.

##### Command-Line Interface

-   Properly handle the `--silence-deprecation` flag.

-   Handle the `--fatal-deprecation` and `--future-deprecation` flags for
    `--interactive` mode.

### [`v1.77.1`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1771)

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.0...1.77.1)

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.75.0...1.76.0)

-   Throw errors for misplaced statements in keyframe blocks.

-   Mixins and functions whose names begin with `--` are now deprecated for
    forwards-compatibility with the in-progress CSS functions and mixins spec.
    This deprecation is named `css-function-mixin`.
