Is there any change in Gitlab API response headers from version 16.4 on GitLab SAAS?

Currently Gitlab is on 16.4 version GitLab Enterprise Edition 16.4.0-pre e920065c29c

Is there any change in API response from this version?

We have noticed the change in response headers.
e.g., Earlier ‘X-Total’ is now ‘x-total’,
Earlier ‘X-Next-Page’ is now ‘x-next-page’.
