You should not use this version in production as it does contain bugs and breaking changes will probably be made until the MyBB. 릴리스 후보가 게시될 때까지 변경 사항이 적용될 수 있으므로 프로덕션 환경에서 사용해서는 안 됩니다. If you want to dive into the source code of the new, laravel based, MyBB., you can do it here in the official repository.
