A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an
incompatible breaking change needing manual actions.
### To 10.0.0
For releases with `usePassword: true`, the value `sentinel.usePassword` controls whether the password authentication also applies to the sentinel port. This defaults to `true` for a secure configuration, however it is possible to disable to account for the following cases:
* Using a version of redis-sentinel prior to `5.0.1` where the authentication feature was introduced.
* Where redis clients need to be updated to support sentinel authentication.
If using a master/slave topology, or with `usePassword: false`, no action is required.
### To 8.0.18
For releases with `metrics.enabled: true` the default tag for the exporter image is now `v1.x.x`. This introduces many changes including metrics names. You'll want to use [this dashboard](https://github.com/oliver006/redis_exporter/blob/master/contrib/grafana_prometheus_redis_dashboard.json) now. Please see the [redis_exporter github page](https://github.com/oliver006/redis_exporter#upgrading-from-0x-to-1x) for more details.
