Overview

Unless otherwise noted in the change logs, the IBM Cloud provider version enables Red Hat OpenShift APIs and features that are at beta. Red Hat OpenShift alpha features are disabled and subject to change.

Check the Security Bulletins on IBM Cloud Status for security vulnerabilities that affect Red Hat OpenShift on IBM Cloud. You can filter the results to view only Kubernetes Service security bulletins that are relevant to Red Hat OpenShift on IBM Cloud. Change log entries that address other security vulnerabilities but don't include an IBM security bulletin are for vulnerabilities that are not known to affect Red Hat OpenShift on IBM Cloud in normal usage. If you run privileged containers, run commands on the workers, or execute untrusted code, then you might be at risk.

Master patch updates are applied automatically. Worker node patch updates can be applied by reloading or updating the worker nodes. For more information about major, minor, and patch versions and preparation actions between minor versions, see Red Hat OpenShift versions.
