(RHSA-2021:3925) Important: Red Hat Advanced Cluster Management 2.3.3 bug fix, security, and image updates

Red Hat Advanced Cluster Management for Kubernetes 2.3.3 images

Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with
security policy built in.

This advisory contains the container images for Red Hat Advanced Cluster Management for Kubernetes, which fix several bugs and provide security updates. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release:

https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.3/html/release_notes/

Note: Because Red Hat OpenShift Container Platform version 4.9 was just released, the functional testing of the compatibility between Red Hat Advanced Cluster Management 2.3.3 and Red Hat OpenShift Container Platform version 4.9 is still in progress.
