- In kubelet, log verbosity and flush frequency can also be configured via the configuration file and not just via command line flags. In other commands (kube-apiserver, kube-controller-manager), the flags are listed in the "Logs flags" group and not under "Global" or "Misc". The type for `-vmodule` was made a bit more descriptive (`pattern=N,...` instead of...

    // We know that a fresh connection was created if the server recorded a request with sequence
    // number 0. Since the client may have attempted to reuse the broken connection just before
    // creating a fresh connection, the server may have recorded 2 requests at this point. The order
    // of recording is non-deterministic.

     * <p>Be careful when targeting an older SDK than you are building against (most commonly when

- Kubelet metrics have been changed to buckets. 
  For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]

now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm init phase kubeconfig all` or just `kubeadm init` will now generate the new `super-admin.conf` file. The cluster admin can then decide to keep the file present on a node host or move it to a safe location. `kubadm certs renew` will renew the certificate in `super-admin.conf` to one...

  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

* Fixed a bug in the apiserver storage that could cause just-added finalizers to be ignored on an immediately following delete request, leading to premature deletion. ([#77619](https://github.com/kubernetes/kubernetes/pull/77619), [@caesarxuchao](https://github.com/caesarxuchao))

  Distributions or administrators of Kubernetes may want to control that new Service CIDRs added to the cluster does not overlap with other networks on the cluster, that only belong to a specific range of IPs or just simple retain the existing behavior of only having one ServiceCIDR per cluster.  An example of a Validation Admission Policy to achieve this is:

  If you maintain controllers that previously relied on matchLabelKeys (for instance, to simulate scheduling), 
  you likely no longer need to handle matchLabelKeys directly. Instead, you can just rely on the labelSelector field going forward.
  
  Additionally, a new feature gate `MatchLabelKeysInPodTopologySpreadSelectorMerge`, which is enabled by default, has been
