GitLab 12.1 (July 2019) introduces a difference:
"Merge Requests for Confidential Issues"
When discussing, planning and resolving confidential issues, such as security vulnerabilities, it can be particularly challenging for open source projects to remain efficient since the Git repository is public.
As of 12.1, it is now possible for confidential issues in a public project to be resolved within a streamlined workflow using the Create confidential merge request button, which helps you create a merge request in a private fork of the project.
See "Confidential issues" from issue 58583.
A similar feature exists in GitHub, but involves the creation of a special private fork, called "maintainer security advisory".
GitLab 13.5 (Oct. 2020) will add reviewers, which was already available for GitHub before.
