group now allows providing the user uid. ([#49677](https://github.com/kubernetes/kubernetes/pull/49677), [@dims](https://github.com/dims))

* After a kubelet rotates its client cert, it now closes its connections to the API server to force a handshake using the new cert. Previously, the kubelet could keep its existing connection open, even if the cert used for that connection was expired and rejected by the API server. ([#49899](https://github.com/kubernetes/kubernetes/pull/49899), [...

non-interface terms must be pairwise disjoint (the pairwise intersection of the type sets must be empty).
Given a type parameter <code>P</code>:
</p>

<pre>
interface {
	P                // illegal: P is a type parameter
	int | ~P         // illegal: P is a type parameter
	~int | MyInt     // illegal: the type sets for ~int and MyInt are not disjoint (~int includes MyInt)

- Exposes and sets a default timeout for the SubjectAccessReview client for DelegatingAuthorizationOptions ([#96152](https://github.com/kubernetes/kubernetes/pull/96152), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery and Cloud Provider]

- For statically provisioned PVs, if its volume source is CSI type or it has migrated annotation, when it's deleted, the PersisentVolume controller won't changes its phase to the Failed state. 
  

*   A new service annotation `service.beta.kubernetes.io/azure-dns-label-name` now sets the Azure DNS label for a public IP address. ([#47849](https://github.com/kubernetes/kubernetes/pull/47849),[ @tomerf](https://github.com/tomerf))

- kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version.
- kubeadm now automatically sets the `--pod-infra-container-image` flag when starting the kubelet.

### Bug or Regression

- Fixes a race condition in the iptables mode of kube-proxy in 1.27 and later
  that could result in some updates getting lost (e.g., when a service gets a
  new endpoint, the rules for the new endpoint might not be added until
  much later). ([#122815](https://github.com/kubernetes/kubernetes/pull/122815), [@wedaly](https://github.com/wedaly)) [SIG Network]

- DRA: scheduling pods is up to 16x faster, depending on the scenario. Scheduling throughput depends a lot on cluster utilization. It is higher for lightly loaded clusters with free resources and gets lower when the cluster utilization increases. ([#127277](https://github.com/kubernetes/kubernetes/pull/127277), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Architecture, Auth, Etcd, Instrumentation, Node, Scheduling and Testing]

- For statically provisioned PVs, if its volume source is CSI type or it has migrated annotation, when it's deleted, the PersisentVolume controller won't changes its phase to the Failed state. 
  

- Resolves a potential issue with GC and NS controllers which may delete objects after getting a 404 response from the server during its startup. This PR ensures that requests to aggregated APIs will get 503, not 404 while the APIServiceRegistrationController hasn't finished its job.
