upgrades in production environments carries significant risk. - Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily. - If you plan to use `mc admin update`, MinIO process must have write access to the parent directory where the binary is present on the host system. - `mc admin update` is not supported and should...

acquiring certificates ensure the corresponding domain names are set as per the standard [DNS naming conventions](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#pod-identity) in a Kubernetes StatefulSet (for a distributed MinIO setup). Then create a secret using ```bash kubectl create secret generic tls-ssl-minio --from-file=path/to/private.key --from-file=path/to/public.crt ``` Then install the chart, specifying that you want to use the TLS secret: ```bash helm install --set ...

    *   reflector_lists_total
    *   reflector_short_watches_total
    *   reflector_watch_duration_seconds
    *   reflector_watches_total
    * While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable. 
* Fix keymutex issues which may crash in some platforms. ([#74386](https://github.com/kubernetes/kubernetes/pull/74386), [@danielqsj](https://github.com/danielqsj))
