+### Data File
+

 * [#11254](https://github.com/netbox-community/netbox/issues/11254) - Introduce the `X-Request-ID` HTTP header to annotate the unique ID of each request for change logging
 * [#11440](https://github.com/netbox-community/netbox/issues/11440) - Add an `enabled` field for device type interfaces
 * [#11517](https://github.com/netbox-community/netbox/issues/11517) - Standardize the inclusion of related objects across the entire UI
