# 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. ## v6.12 - ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled.
