I notice this also that there is not an upgrade path. 1.0.8 is out and as far as Softaculous is concerned you have to uninstall and reinstall thirtybees to get the new versions.
This it seems like something I could look at at some point, I just dont want to step on anyone's toes if this is in the works already.
