(or even be just another bound type parameter).
In a process of repeated simplification, the bound type parameters in each type
argument are substituted with the respective type arguments for those type
parameters until each type argument is free of bound type parameters.
</p>

<p>
If type arguments contain cyclic references to themselves
through bound type parameters, simplification and thus type
inference fails.

- One new field "InternalTrafficPolicy" in Service is added.
  It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only.
  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

* Fixes issue where subpath readOnly mounts failed ([#63045](https://github.com/kubernetes/kubernetes/pull/63045), [@msau42](https://github.com/msau42))
* Fix in vSphere Cloud Provider to report disk is detach when VM is not found. ([#62220](https://github.com/kubernetes/kubernetes/pull/62220), [@abrarshivani](https://github.com/abrarshivani))

* attachdetach controller attaches volumes immediately when Pod's PVCs are bound ([#66863](https://github.com/kubernetes/kubernetes/pull/66863), [@cofyc](https://github.com/cofyc))

        * At Metadata audit level or higher, an annotation with key "mutation.webhook.admission.k8s.io/round_{round idx}_index_{order idx}" gets logged with JSON payload indicating a webhook gets invoked for given request and whether it mutated the object or not.

  - Remove redundant log lines and reduce severity around parsing kubeEnv
  - Don't treat nodes created by virtual kubelet as nodes from non-autoscaled node groups
  - Remove redundant logging around calculating node utilization
  - Add configurable `--network` and `--rm` flags for docker in `Makefile`

### **Application Autoscaling**

Another feature moving to GA in v1.22 is CSI Service Account Token support. This feature allows CSI drivers to use pods' [bound service account tokens](https://kubernetes.io/docs/reference/access-authn-authz/service-accounts-admin/#bound-service-account-token-volume) instead of a more privileged identity. It also provides control over to re-publishing these volumes, so that short-lived tokens can be refreshed.

- Fixed consolidate logs for `instance not found` error
  Fixed skip `not found` nodes when reconciling LB backend address pools ([#105188](https://github.com/kubernetes/kubernetes/pull/105188), [@nilo19](https://github.com/nilo19))

* Bump version of prometheus-to-sd to 0.2.6 to decrease log noise and include latest security patches. ([#64963](https://github.com/kubernetes/kubernetes/pull/64963), [@loburm](https://github.com/loburm))
* Fixes issue for readOnly subpath mounts for SELinux systems and when the volume mountPath already existed in the container image. ([#64351](https://github.com/kubernetes/kubernetes/pull/64351), [@msau42](https://github.com/msau42))
