-## v8
-
-- Documentation at https://redis.uptrace.dev/
-
-- All commands require `context.Context` as a first argument, e.g. `rdb.Ping(ctx)`. If you are not
-  using `context.Context` yet, the simplest option is to define global package variable
-  `var ctx = context.TODO()` and use it when `ctx` is required.
-
-- Full support for `context.Context` canceling.
-
-- Added `redis.NewFailoverClusterClient` that supports routing read-only commands to a slave node.
-
-- Added `redisext.OpenTemetryHook` that adds
-  [Redis OpenTelemetry instrumentation](https://redis.uptrace.dev/tracing/).
-
-- Redis slow log support.
-
-- Ring uses Rendezvous Hashing by default which provides better distribution. You need to move
-  existing keys to a new location or keys will be inaccessible / lost. To use old hashing scheme:
-
-```go
-import "github.com/golang/groupcache/consistenthash"
-
-ring := redis.NewRing(&redis.RingOptions{
-    NewConsistentHash: func() {
-        return consistenthash.New(100, crc32.ChecksumIEEE)
-    },
-})
-```
-
-- `ClusterOptions.MaxRedirects` default value is changed from 8 to 3.
-- `Options.MaxRetries` default value is changed from 0 to 3.
-
-- `Cluster.ForEachNode` is renamed to `ForEachShard` for consistency with `Ring`.
-
-## v7.3
-
-- New option `Options.Username` which causes client to use `AuthACL`. Be aware if your connection
-  URL contains username.
-
-## v7.2
-
-- Existing `HMSet` is renamed to `HSet` and old deprecated `HMSet` is restored for Redis 3 users.
-
-## v7.1
-
-- Existing `Cmd.String` is renamed to `Cmd.Text`. New `Cmd.String` implements `fmt.Stringer`
-  interface.
-
-## v7
-
-- _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.
-
-## v6.15
-
-- 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. See
-  https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup
