### Release Notes

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

### [`v1.77.7`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1777)

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.77.6...1.77.7)

-   Declarations that appear after nested rules are deprecated, because the
    semantics Sass has historically used are different from the semantics
    specified by CSS. In the future, Sass will adopt the standard CSS semantics.

    See [the Sass website](https://sass-lang.com/d/mixed-decls) for details.

-   **Potentially breaking bug fix:** `//` in certain places such as unknown
    at-rule values was being preserved in the CSS output, leading to potentially
    invalid CSS. It's now properly parsed as a silent comment and omitted from the
    CSS output.

### [`v1.77.6`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1776)

[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)

-   Fully trim redundant selectors generated by `@extend`.

### [`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.

### [`v1.77.2`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1772)

[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)

-   Fix a crash that could come up with importers in certain contexts.

### [`v1.77.0`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1770)

[Compare Source](https://togithub.com/sass/dart-sass/compare/1.76.0...1.77.0)

-   *Don't* throw errors for at-rules in keyframe blocks.

### [`v1.76.0`](https://togithub.com/sass/dart-sass/blob/HEAD/CHANGELOG.md#1760)

[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`.
