     <h2>What's new</h2>
     <p>Full changelog for older versions <a href="https://github.com/tamius-han/ultrawidify/blob/master/CHANGELOG.md">is available here</a>.</p>
-    <p class="label">5.1.6</p>
+    <p class="label">5.1.7</p>
     <ul>
-      <li>Added new config for disney+ (courtesy of @MStefan99)</li>
-      <li>Chrome hardware acceleration is bugged and cannot be worked around in-extension. Only way to fix this is for users to change their Google Chrome settings. Added naggathon with instructions into the extension popup.</li>
+      <li>In some situations, video aligned would move the video by non-whole number of pixels. On some hardware configuration, this would introduce a thin vertical white line. This issue <i>should</i> be fixed now.</li>
