Merge request changes not returned by the API

[AxelReviron]

Hello,

I've encountered an issue where the changes from a merge request response appear to be empty. Here's my code:

$mergeRequestChanges = $this->gitlab->mergeRequests()->changes(
    $mergeRequest->project->gitlab_id,
    $gitlabResponse['iid']
);

dd($mergeRequestChanges);

This is the response from the API (some data has been anonymized for confidentiality, but all relevant information is included):

As you can see, my merge request has 2 changes, but they are not returned by the API.

Additionally, I have a question: I've been searching for the following routes in the library but can't find them:

• GET /projects/:id/merge_requests/:merge_request_iid/diffs
• GET /projects/:id/merge_requests/:merge_request_iid/raw_diffs

Are there any plans to implement these ? May I create a pull request for this ?

Thank you.
