+        <p>
+        This version of Cozy features an important change in library management.
+        Previously every file which was imported in your library but couldn't be found anymore was removed from the library during a scan.
+        Now audiobooks are not removed from your library automatically anymore. This prevents accidentally loosing the progress of a audiobook when a file can't be found temporarily.
+        To remove an audiobook from the library simply right-click on it and choose the remove from library option.
+        </p>
+        <ul>
+          <li>The download option will be enabled for audiobooks on removable or network drives automatically for each new storage location you add.</li>
+          <li>Unavailable books (books where a file can't be found) can now be opened to display the book detail view. They will be flagged with a little unavailable tag</li>
+          <li>Under the hood improvements in the media importer</li>
+          <li>Media playback is rewritten from ground up. It's far more stable than before.</li>
+          <li>Fix: When a different system language than English is used Cozy created two folders in the users home directory on the first startup, a translated and a English one. Now only the translated folder will be created.</li>
+          <li>Fix: A wrong mouse pointer was displayed with some pointer themes</li>
+          <li>Fix: A memory leak in the importer</li>
+          <li>Fix: The playback speed of a book was not remembered correctly</li>
+          <li>Fix: The desktop integration did not respect the switch author and reader setting</li>
+          <li>As always, updated translations thanks to all of the translators!</li>
