## Upgrading
|
||||
|
||||
### To 4.0.0
|
||||
|
||||
The `metrics-generator` component kind has switched from a 'Deployment' to a 'Statefulset'. More details at [Github issue](https://github.com/bitnami/charts/pull/31495).
|
||||
|
||||
### To 3.8.0
|
||||
|
||||
This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850).
