## 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
- Added support for [RESP3](https://github.com/antirez/RESP3/blob/master/spec.md) protocol.
- Removed `Pipeline.Close` since there is no real need to explicitly manage pipeline resources.
`Pipeline.Discard` is still available if you want to reset commands for some reason.
- Replaced `*redis.Z` with `redis.Z` since it is small enough to be passed as value.
