    1414- It introduces a new attribute, `QuerySet._known_related_object`. This is only used to automatically set the reverse relation when creating objects through a related manager. When you're accessing `tournament.pool_set.all()`, `tournament.pool_set.all()._known_related_object == ('tournament', tournament)`, so each pool objects gets its 'tournament' attribute set to the original `tournament` instance.
    15 - It caches the reverse relation in several `get_prefetch_query_set()` methods, as explained above.
     15- It caches the reverse relation in several `get_prefetch_query_set()` methods, as explained above. This isn't implemented for many-to-many relations since there's no way to be sure that we have all the objects we need to build the reverse relation.
