# GET /api/v4/projects/{}/merge_requests/{}/changes is deprecated

GitLab API deprecated GET /api/v4/projects/{id}/merge_requests/{id}/changes without giving a shutdown date yet.

The endpoint GET /api/v4/projects/{id}/merge_requests/{id}/changes has been deprecated without a shutdown date. GitLab API plans to remove this endpoint in v5 of the API. Once removed, requests to this path will fail.
