+<h2>2026-08-22 - Better Volume & Private Songs</h2>
 <p>
-You can now mark songs as private, so they will only be visible to you.  This
-works basically the same way as it does for playlists.
+This update has two parts:
 </p>
+<ul>
+    <li>The volume slider (on desktop) now has a proper audio taper, making it
+        a little easier to find the volume you want.
+    </li>
