Clip-o-tron - OF1 version still working on OF2 - need to install new one?

When beta testing OF2 it was possible to install the clipper from OF1 which I did. This is still working well. Now I notice that a new version has been made available.

Do I install the new one? Do I need to uninstall the old one, or just install over the other version?
Any advice gratefully received.
