(Default/Stable): It has been tested by users on the develop and nightly branches and it’s not known to have any major issues. This version will receive updates approximately monthly. On GitHub, this is the `master` branch.
(Beta): This is the testing edge. Released after being tested in the nightly branch to ensure no immediate issues. New features and bug fixes are released here first after nightly. It can be considered semi-stable but is still `beta`. This version will receive updates either weekly or biweekly depending on development.
!!! warning "**Warning: You may not be able to go back to `master` after switching to this branch.** On GitHub, this is a snapshot of the `develop` branch at a specific point in time."
(Alpha/Unstable) : This is the bleeding edge. It is released as soon as the 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.
