+      We've updated the packager to use the <a href="https://docs.turbowarp.org/new-compiler">new compiler</a> to make projects run even faster.
+    </p>
+    <p>
+      If your project relies on extensions that require the old compiler, a version of the packager using the old compiler will be available on <a href="https://packager-legacy.turbowarp.org/">packager-legacy.turbowarp.org</a> indefinitely.
