I think it's time we consider setting up a dev branch and master branch. The idea has been suggested in the past, and I think we could benefit a lot from following that advice now.

We can file bug fixes over to master, and put breaking changes on dev. This should make it easier to push out bug fixes on the current minor version.

I think we should keep master as the default branch, and we can manually edit PRs to go to the dev branch when appropriate.
