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

- 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.

* PVC may not be synced to controller local cache in time if PV is bound by external PV binder (e.g. kube-scheduler), double check if PVC is not found to prevent reclaiming PV wrongly. ([#67062](https://github.com/kubernetes/kubernetes/pull/67062), [@cofyc](https://github.com/cofyc))

* 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))

### **Application Autoscaling**

        * 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.

* 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))

  - 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`

- When using `kubectl logs <pod-name>` and the pod is not found, the error message now includes the namespace. Previously, the message would be "Error from server (NotFound): pods "my-pod-name" not found". Now, it reflects the namespace in the message as follows: "Error from server (NotFound): pods "my-pod-name" not found in namespace "default"".

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.
