 ### Breaking Changes
 
 * PostgreSQL 11 is no longer supported (due to adopting Django 4.2). NetBox v3.6 requires PostgreSQL 12 or later.
-* The `napalm_driver` and `napalm_args` fields (which were deprecated in v3.5) have been removed from the platform model.
+* The `device_role` field on the Device model has been renamed to `role`. The `device_role` field has been temporarily retained on the REST API serializer for devices for backward compatibility, but is read-only.
+* The `choices` array field has been removed from the CustomField model. Any defined choices are automatically migrated to CustomFieldChoiceSets, accessible via the new `choice_set` field on the CustomField model.
+* The `napalm_driver` and `napalm_args` fields (which were deprecated in v3.5) have been removed from the Platform model.
