 - 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.
