+    New, more informative message about the release you're running and updating it.
+    <p></p>
+    DDE version 3 does have *some* incompatibilities with DDE version 2,
+    but overall has lots of improvements.
+    We do NOT recommend switching to version 3 before a big demo of your code!
+    <p></p>
+    Haddington will help you upgrade your version 2 code to
+    version 3, should you chose to make the switch and find incompatibilities.<br/>
+    You can see differences between v2 and v3 by looking at the Release Notes in:<br/>
