I generally have v0, v1, v2, ... as the main branch. All changes are made in feature branches (with unimportant naming) and are merged into the appropriate main branch. If we need to support releases then a v1.2 or similar branch is created for each release. Fixes are then added there (as well as the main branch usually). I generally don't create branches for prod or releases, just tags. I also don't have a `next` branch. Whatever is on the version branch is "next" to be released.
