# Changelog## Unreleased- Cluster and Ring pipelines process commands for each node in its own goroutine.## 6.14- Added Options.MinIdleConns.- Added Options.MaxConnAge.- PoolStats.FreeConns is renamed to PoolStats.IdleConns.- Add Client.Do to simplify creating custom commands.- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.- Lower memory usage.## 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.- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.- Dialer.KeepAlive is set to 5 minutes by default.## v6.12- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled.
