Can we just upload Verionum's compiled 08 Windows client as a "release" or does that involve some sort of process in git?
Er, I don't know. I've never travelled the "release" path in github (I have that joyful experience to look forward to with Slimcoin at some point soon). For now, all I can do is point you to the GitHub docs (
https://help.github.com/articles/about-releases/) - which, on a quick skim do imply that git is actively involved.
Cheers
