(Default/Stable): It has been tested by users on the develop and nightly branches and it’s not known to have any major issues. On GitHub, this is the `master` branch.
(Beta): This is the testing edge. Released after tested in nightly to ensure no immediate issues. New features and bug fixes released here first after nightly. It can be considered semi-stable, but is still `beta`.
(Alpha/Unstable): This is the bleeding edge. It is released as soon as code is committed and passes all automated tests. This build may have not been used by us or other users yet. There is no guarantee that it will even run in some cases. This branch is only recommended for advanced users. Issues and self investigation are expected in this branch.
