* The new ``stdout`` argument for :func:`~django.db.models.signals.pre_migrate`
and :func:`~django.db.models.signals.post_migrate` signals allows redirecting
output to a stream-like object. It should be preferred over
:py:data:`sys.stdout` and :py:func:`print` when emitting verbose output in
order to allow proper capture when testing.
