My favorite new additions: - django.core.cache.backends.redis.RedisCache cache backend provides built-in support for caching with Redis - The runserver management command now supports the --skip-checks option. - The shell command now respects sys.__interactivehook__ at startup. This allows loading shell history between interactive sessions. As a consequence, readline is no longer loaded if running in isolated mode. - New QuerySet.contains(obj) method returns whether the queryset contains the given object. This tries to perform the query in the simplest and fastest way possible. - Lookup expressions may now be used in QuerySet annotations, aggregations, and directly in filters.
