The previous --force-branch option is renamed --checkout (the old name preserved for backwards compatibility).

Usage:
  --checkout         Create a branch and check it out.
  --create           Create a branch.
  -n, --name <name>  Specify the name of branch to create or reset.
                       This will force the branch using 'git branch -f '.
  -q, --quiet        Quiet.
