+The fifth major release of containerd includes a mix of new features and
+expanded support, such as support for CGroups v2, expanded SELinux support,
+support for Windows on Kubernetes through CRI, and support for snapshotters
+based on shared remote storage. All significant bug and stability fixes included
+in this release are also available on supported prior releases. Like previous
+major releases, what is not included in this release is also important. There
+are only two small additions to the API with no backwards incompatible changes,
+allowing client and daemon upgrades to be done independently without disruption.
+The incredible increase in usage of containerd over the last year has shown the
+value of our core principles to easily expand support for different use cases
+while driving toward ever increasing stability.
