I'm not so sure about this one. Don't you have a Help -> About dialog box somewhere in your app?
It would be nice it the control told you what version you have, when it tells you that you have the latest version.
Either show it in the label "You have the latest version (3.1.7)"or it the user clicks the drop down it could be a drop down option
