I finally fixed the problem where you could back-space too far past the beginning of the command and "break" the command -- for real this time ;-)
This is a bug fix release. Please read the release notes for the previous alphas (sorry, I know, I hate that, but it's the best list of features right now -- I'll be working on that).
I've fixed the crash on Tab-Complete which occurred when there was nothing found to complete, and I've added proper version information in preparation for making this click-once deployable.
