Thanks Jaspal.  A follow-up here... Are you saying a major version upgrade package will update all plugin applications to A version that is compatible with the upgrade?  But maybe it's not the most recent update to the plugin since the major upgrade version only contained the updates to the plugins at that time?  So like we upgrade to Xanadu 4 and that comes with HAM application v 1.1 for Xanadu but there's actually a 1.2 for Xanadu.  Does that make sense?
