- ## [8.11.4](https://github.com/go-redis/redis/compare/v8.11.3...v8.11.4) (2021-10-04)
-
-
- ### Features
-
- * add acl auth support for sentinels ([f66582f](https://github.com/go-redis/redis/commit/f66582f44f3dc3a4705a5260f982043fde4aa634))
- * add Cmd.{String,Int,Float,Bool}Slice helpers and an example ([5d3d293](https://github.com/go-redis/redis/commit/5d3d293cc9c60b90871e2420602001463708ce24))
- * add SetVal method for each command ([168981d](https://github.com/go-redis/redis/commit/168981da2d84ee9e07d15d3e74d738c162e264c4))
-
-
-
- ## v8.11
-
- - Remove OpenTelemetry metrics.
- - Supports more redis commands and options.
-
- ## v8.10
-
- - Removed extra OpenTelemetry spans from go-redis core. Now go-redis instrumentation only adds a
- single span with a Redis command (instead of 4 spans). There are multiple reasons behind this
- decision:
-
- - Traces become smaller and less noisy.
- - It may be costly to process those 3 extra spans for each query.
- - go-redis no longer depends on OpenTelemetry.
-
- Eventually we hope to replace the information that we no longer collect with OpenTelemetry
- Metrics.
-
- ## v8.9
-
- - Changed `PubSub.Channel` to only rely on `Ping` result. You can now use `WithChannelSize`,
- `WithChannelHealthCheckInterval`, and `WithChannelSendTimeout` to override default settings.
-
- ## v8.8
-
- - To make updating easier, extra modules now have the same version as go-redis does. That means that
- you need to update your imports:
-
- ```
- github.com/go-redis/redis/extra/redisotel -> github.com/go-redis/redis/extra/redisotel/v8
- github.com/go-redis/redis/extra/rediscensus -> github.com/go-redis/redis/extra/rediscensus/v8
- ```
-
- ## v8.5
-
- - [knadh](https://github.com/knadh) contributed long-awaited ability to scan Redis Hash into a
- struct:
-
- ```go
- err := rdb.HGetAll(ctx, "hash").Scan(&data)
-
- err := rdb.MGet(ctx, "key1", "key2").Scan(&data)
- ```
-
- - Please check [redismock](https://github.com/go-redis/redismock) by
- [monkey92t](https://github.com/monkey92t) if you are looking for mocking Redis Client.
-
- ## v8
-
- - 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
