For #38005, the generated change contains item about overload API:

  - Method `ContainerGroupsOperations.update` has a new overload `def update(self: None, resource_group_name: str, container_group_name: str, resource: IO[bytes], content_type: str)`
  - Method `ContainersOperations.execute_command` has a new overload `def execute_command(self: None, resource_group_name: str, container_group_name: str, container_name: str, container_exec_request: IO[bytes], content_type: str)`
  - Method `ContainerGroupProfilesOperations.create_or_update` has a new overload `def create_or_update(self: None, resource_group_name: str, container_group_profile_name: str, container_group_profile: ContainerGroupProfile, content_type: str)`

  - Method `ContainerGroupProfilesOperations.patch` has a new overload `def patch(self: None, resource_group_name: str, container_group_profile_name: str, properties: ContainerGroupProfilePatch, content_type: str)`
  - Method `ContainerGroupProfilesOperations.patch` has a new overload `def patch(self: None, resource_group_name: str, container_group_profile_name: str, properties: IO[bytes], content_type: str)`

However, MGMT SDK changelog usually don't report about overload API so we hope tool doesn't report it anymore.
