This commit introduces the ability to process URLs like redis://localhost/1?dial_timeout=10s and similar. Go programs which were providing a configuration tunable (e.g. CLI flag, config entry or environment variable) to configure the Redis connection now don't need to perform this task themselves. * chore: add links to readme * chore: fix discussions link * empty hooks.withContext removed * chore: gofmt * chore: use conventional commits and auto-generate changelog * feat: add acl auth support for sentinels * chore: swap to acl auth at the test-level * Add support for BLMove command * chore: update dependencies * chore: update link * feat: add SetVal method for each command * feat: add Cmd.{String,Int,Float,Bool}Slice helpers and an example * chore: tweak GH actions to run all jobs * chore: add Lua scripting example * Fix Redis Cluster issue during roll outs of new nodes with same addr (#1914) * fix: recycle connections in some Redis Cluster scenarios This issue was surfaced in a Cloud Provider solution that used for rolling out new nodes using the same address (hostname) of the nodes that will be replaced in a Redis Cluster, while the former ones once depromoted as Slaves would continue in service during some mintues for redirecting traffic. The solution basically identifies when the connection could be stale since a MOVED response will be returned using the same address (hostname) that is being used by the connection. At that moment we consider the connection as no longer usable forcing to recycle the connection. * chore: lazy reload when moved or ask * chore: use conv commit message * chore: release v8.11.4 (release.sh) * fix: add whitespace for avoid unlikely colisions * fix: format * chore: fix links * chore: use ctx parameter in cmdInfo * Bump github.com/onsi/ginkgo from 1.16.4 to 1.16.5 (#1925) Bumps [github.com/onsi/ginkgo](https://github.com/onsi/ginkgo) from 1.16.4 to 1.16.5. - [Release notes](https://github.com/onsi/ginkgo/releases) - [Changelog](https://github.com/onsi/ginkgo/blob/master/CHANGELOG.md) - [Commits](https://github.com/onsi/ginkgo/compare/v1.16.4...v1.16.5) --- updated-dependencies: - dependency-name: github.com/onsi/ginkgo dependency-type: direct:production update-type: version-update:semver-patch ...

-### OpenTelemetry Example 
-Prints spans and metrics to the console.
-#### To Run:
- `docker-compose up -d`
- `go run .`
+# Example for go-redis OpenTelemetry instrumentation

-When you're finished, be sure to run `docker-compose down` to shutdown
-the redis server.
+See [Monitoring performance and errors](https://redis.uptrace.dev/guide/tracing.html) for details.

+This example requires Redis Server on port `:6379`. You can start Redis Server using Docker:
+
+```shell
+docker-compose up -d
+```
+
+You can run this example with different OpenTelemetry exporters by providing environment variables.
+
+**Stdout** exporter (default):
+
+```shell
+go run .
+```
+
+**Jaeger** exporter:
+
+```shell
+OTEL_EXPORTER_JAEGER_ENDPOINT=http://localhost:14268/api/traces go run .
+```
+
+**Uptrace** exporter:
+
+```shell
+UPTRACE_DSN="https://<token>@uptrace.dev/<project_id>" go run .
+```

-To run this example you need a Redis server. You can start one with Docker:
-
-```shell
-make up
-```
-
-Then run the example:
-
-```shell
-go run main.go
