 * logging: allow to enable logging at will and export said logs to a file
 
-### v4.4.7 (Current)
+### v4.4.8 (Current)
+
+* Fixed the bug where on pages with more than one video, the list of available videos in the extension popup wouldn't remove videos that are no longer displayed on site. This resulted in extension listing videos that were no longer on the page. Reboot or navigation would also not clear the list if navigating between various pages on the same host.
+* Fixed the chrome-only bug where on sites with more than one video, the number wouldn't get hidden when the extension popup closed.
+
+### v4.4.7
 
 * Removed unnecessary font files and image files from the package.
 * LoggerUI is now functional.

     <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">4.4.7</p>
+    <p class="label">4.4.8</p>
     <ul>
-      <li><b>[4.4.7.1]</b> CSS fixes</li>
-      <li><b>[4.4.7.1~2]</b> Delay CSS changes if video dimensions are invalid (attempt to fix youtube alignment problems
-      that appear in certain circumstances). 4.4.7.2 increased number of retries.
+      <li>
+        Fixed the bug where on pages with more than one video, the list of available videos in the extension popup
+        wouldn't remove videos that are no longer displayed on site. This resulted in extension listing videos that
+        were no longer on the page. Reboot or navigation would also not clear the list if navigating between various
+        pages on the same host.
+      </li>
+      <li>
+        Fixed the chrome-only bug where on sites with more than one video, the number wouldn't get hidden when the
+        extension popup closed.
       </li>
-      <li>Removed unnecessary font files and image files from the package.</li>
-      <li>(For testing/debugging purposes) Logger UI in swatter mode is now somewhat functional and user-friendly.</li>
     </ul>
