Changelog

v6.13

Ring got new options called HashReplicas and Hash. It is recommended to set HashReplicas = 1000 for better keys distribution between shards.
Cluster client was optimized to use much less memory when reloading cluster state.
ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres.

ClusterClient got new option called ClusterSlots which allows to build cluster of normal Redis Servers that don't have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup
