+        <p>New features and bugfixes in this release:</p>
+        <ul>
+          <li>The header bar player controls have been redesigned, partly based on the design of Elisa. The header bar is resizeable and can be fully collapsed to just a minimal toolbar.</li>
+          <li>The left sidebar menu in desktop mode has been redesigned. It's now using similar buttons to the ones used in the bottom navigation bar in mobile mode.</li>
+          <li>The audio backend has been re-written from scratch. It can now handle multiple backends: libVLC, gstreamer and Qt Multimedia. Kasts will use libVLC as default backend when available, which should solve common issues: volume control is now available through the main toolbar and seeking should no longer make the audio hang.</li>
+          <li>The settings menu was ported to the new form components.</li>
+          <li>Support for chapter images was added.</li>
+          <li>Timestamps mentioned in episode descriptions are now clickable, which will make the audio jump to that point in the episode.</li>
+          <li>Images in headers are now clickable. This will open a fullscreen view of the image in question.</li>
+          <li>The subscribe button is now disabled when a podcast has just been added.</li>
+          <li>Several issues with right-to-left language layouts were solved.</li>
+        </ul>
