## Supported Versions

Information about supported Kubernetes versions can be found on the
[Kubernetes version and version skew support policy] page on the Kubernetes website.

## Reporting a Vulnerability

Instructions for reporting a vulnerability can be found on the
[Kubernetes Security and Disclosure Information] page.

- Existing or newer buckets can be created with versioning enabled and eventually can be suspended as well. Existing versions of objects stay as is and can still be accessed using the version ID.
- All versions, including delete-markers should be deleted before deleting a bucket.
