I'm not a library developer but is there a way in the library to trigger some kind of event that checks if there's a new version available? I know in VB/Delphi you could have a context menu that would be able to do something. Other than that maybe a push service could be setup or integrated with the forum such that a library poster could trigger a push to all subscribers, similar to "alerts"? A less than elegant solution is to just click "watch thread"
