The old format won't be getting any new features and only the most critical bugfixes.  As a consequence, you should upgrade this instance.							&lt;/p&gt;
+&lt;p style=&quot; margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;The upgrade will create a new instance with the same contents as the current one, in the new format. The original instance will remain untouched, in case anything goes wrong in the process.							&lt;/p&gt;
