<p><em>Sourced from <a href="https://github.com/sass/dart-sass/blob/main/CHANGELOG.md">sass's changelog</a>.</em></p>
<blockquote>
<h2>1.85.0</h2>
<ul>
<li>No longer fully trim redundant selectors generated by <code>@extend</code>. This caused
unacceptable performance issues for certain heavy users of <code>@extend</code>. We'll
try to find a more performant way to accomplish it in the future.</li>
</ul>
<h2>1.84.0</h2>
<ul>
<li>
<p>Allow newlines in whitespace in the indented syntax.</p>
</li>
<li>
<p><strong>Potentially breaking bug fix</strong>: Selectors with unmatched brackets now always
produce a parser error. Previously, some edge cases like <code>[foo#

)

</code> would compile without error, but this was an unintentional bug.</p>
</li>
<li>
<p>Fix a bug in which various Color Level 4 functions weren't allowed in plain
CSS.</p>
</li>
<li>
<p>Fix the error message for <code>@extend</code> without a selector and possibly other
parsing edge-cases in contexts that allow interpolation.</p>
</li>
</ul>
<h3>Embedded Host</h3>
<ul>
<li>Fixed the implementation of the <code>SassBoolean</code> type to adhere to the spec,
now using a class instead of an interface.</li>
</ul>
<h2>1.83.4</h2>
<ul>
<li>No user-visible changes.</li>
</ul>
<h2>1.83.3</h2>
<ul>
<li>No user-visible changes.</li>
</ul>
<h2>1.83.2</h2>
<ul>
<li>
<p>Properly display deprecation IDs for the JS Sass API.</p>
</li>
<li>
<p>Don't display deprecation IDs for user-defined deprecations.</p>
