Unable to set SCSS variable to CSS variable? : <p>Consider the following SCSS:</p>

<pre><code>$color-black: #000000;

body {
    --color: $color-black;
}
</code></pre>

<p>When it is compiled with node-sass <strong>version 4.7.2</strong>, it produces following CSS:</p>

<pre><code>body {
    --color: #000000; 
}
</code></pre>

<p>When I compile the same SCSS with version <strong>4.8.3 or higher</strong>, it produces following:</p>

<pre><code>body {
    --color: $color-black; 
}
</code></pre>

<p><strong>What am I missing?</strong> I checked release logs, but could not found anything useful. Also, I wonder if this change is genuine why does it have only minor version change? Should it not be a major release?</p>

<p>Also, <strong>what is my alternative?</strong> Should I use <strong>Interpolation</strong>?</p>
