-<h2>Version 2.1.2 / <set date></h2>
+<h2>Version 2.1.2 / 2015-09-07</h2>
+
+PLEASE NOTE the following important information:
+<ul>
+<li>FrSky Taranis X9E users are highly advised to upgrade to this version or its equivalent when provided by FrSky due to the risk of shutdown upon software error that was present in previous versions.</li>
+<li>Telemetry sensors are now no longer continuously being detected, it is now necessary to go on the telemetry setup page and select the "Discover new sensors" menu item. This prevents creation of non-existing sensors in case if transmission errors, and allows deleting sensors that are received but considered uninteresting.</li>
+</ul>
