Branching

How can we branch a project, or clone it into a new project?

There doesn't seem to be any support for it so I tried manually copying the project to a new directory and deleting the collab folder/files but it seems to reconnect directly to the old project.

The main reason I need to do this is actually only because after upgrading unity versions collab thinks I need to catch up with every single changes instead of committing new files so its rendered basically useless because catching up would overwrite the new work.
