Attention Needed
This patch releases updates etcd to v3.5.3 which includes a fix for the data inconsistency issues reported earlier (https://groups.google.com/a/kubernetes.io/g/dev/c/B7gJs88XtQc/m/rSgNOzV2BwAJ). To upgrade etcd for an existing cluster, you need to force upgrade the cluster as described here. If you're running Kubernetes 1.22 or newer, we strongly recommend upgrading etcd as soon as possible.
