Red Hat Advanced Cluster Management for Kubernetes 2.3.3 General
Availability release images, which fix bugs, provide security fixes, and

2. Description:

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_mana
gement_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.
