I am currently looking a lot into git-flow, and trying to figure out, how to use it for the projects I am involved on.
I have looked at the various git-flow tutorial
Is this possible at all with git flow?
Anything is possible using git-flow as a series of best-practices rather than a hard rule. Just open your feature branches from your 1.0 release branch instead of from your develop branch.
1.0
develop
