Changelog

v7.2

Existing HMSet is renamed to HSet and old deprecated HMSet is restored for Redis 3 users.

Existing Cmd.String is renamed to Cmd.Text. New Cmd.String implements fmt.Stringer interface.

Important. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a transactional pipeline.
WrapProcess is replaced with more convenient AddHook that has access to context.Context.
WithContext now can not be used to create a shallow copy of the client.
New methods ProcessContext, DoContext, and ExecContext.
Client respects Context.Deadline when setting net.Conn deadline.
Client listens on Context.Done while waiting for a connection from the pool and returns an error when context context is cancelled.
Add PubSub.ChannelWithSubscriptions that sends *Subscription in addition to *Message to allow detecting reconnections.
time.Time is now marshalled in RFC3339 format. rdb.Get("foo").Time() helper is added to parse the time.
SetLimiter is removed and added Options.Limiter instead.
HMSet is deprecated as of Redis v4.

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.

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.

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
