Threaded IO, Server assisted client caching, and Redis proxy in my opinion is an important milestones. Threaded IO will fully utilize multiple cores; and improvements are amazing. Server assisted caching will reduce client round-trips. Redis proxy will remove the debate of which client library to use, Jedis for example has not allowed reading from replicas or doing multiplexing distributed commands; proxy is gonna solve all those gripes. I can't wait for it to be stable and production ready.
