The `merged_by` field in the [merge request API](https://docs.gitlab.com/ee/api/merge_requests.html#list-merge-requests) has been deprecated in favor of the `merge_user` field which more correctly identifies who merged a merge request when performing actions (merge when pipeline succeeds, add to merge train) other than a simple merge. API users are encouraged to use the new `merge_user` field instead. The `merged_by` field will be removed in v5 of the GitLab REST API.
