Test version ($20/month) - 0.09.20
Patreon version ($5/month) - 0.09.04
Public version (free) - 0.08.12
Not many people have the test version since you have to donate $20 a month for it. The free version will always be available at a minimum, but it is like a month behind current builds.
Here is SuperPowered 0.09.04, I think it is just bug fixes for 0.09.03 though. The developer seems to have dropped the password requirement for now. This is the original/unmodded version.
