<summary>Release Notes for v4.38.0</summary>

<h1>Performance</h1>
<ul>
<li>Improved performance of ProgressPlugin</li>
<li>Improved performance of chunk graph generation
<ul>
<li>This can boost performance when many chunks are used, especially incremental build performance</li>
<li>Modules from parent chunks are now tracked during chunk graph generation, which allows to skip these modules in async chunks. This often renders <code>optimization.removeAvailableModules</code> unneeded, expect in scenarios where chunks are merged during optimization.</li>
</ul>
</li>
<li><code>optimization.removeAvailableModules</code> is now disabled in development mode by default
<ul>
<li><code>optimization.removeAvailableModules</code> will be disabled for all modes in next major release, feel free to disable it in production too if you want extra performance.</li>
</ul>
</li>
</ul>
