Aaahhhh I generally don’t keep an alpha version of a project around.
Generally I’ll commit a beta through Git (we use GitHub to manage everything) which we start with a version of 0.0.1. We go through iterations of the beta until final release. When the final release is committed it gets v1.0.0.
I’m not sure I’d be doing any of that without a proper versioning system in place. The thought of maintaining multiple folders is unbelievably daunting.
