One of my rigs had 0.6.5 both updaters would create an invalid jar.  Would it be possible to have a history of updaters somewhere?  I was able to find my 0.6.5->0.6.5a updater, but in the event that someone is still running a version other than the previous or 0.6.3, then it might be helpful to have the other updaters available so we can catch up and then run the newest updater.
