@ben.boeckel thanks! I see https://gitlab.com/gitlab-org/gitlab-ce/issues/18458 talks about the updated_at value that is present when editing an issue. Can you add the additional info there as well?

Also we should include that you need to be a project owner according to https://gitlab.com/gitlab-org/gitlab-ce/issues/19863#note_13100519.

Updated.
