+    <p>dconf Editor has had a facelift for 3.20. Settings lists have been
+    overhauled, to give a better overview, and each row now includes the
+    description for the setting. Search uses the standard design found in other
+    GNOME applications, making it easier to find, and it can be activated by
+    starting to type.</p>
+    <p>The new version includes a number of new features, too: bookmarks allow
+    you to easily go back to frequently used settings and "use default value"
+    switches allow you to toggle settings you have changed. Copy current page
+    and reset visible keys are other handy functions that have been added.</p>
