- [beta] StatefulSets allow workloads that require persistent identity or per-instance storage to be created and managed on Kubernetes. ([docs](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/)) ([kubernetes/features#137](https://github.com/kubernetes/enhancements/issues/137))

  the Pod won't be stuck in the unschedulable pod pool. ([#119290](https://github.com/kubernetes/kubernetes/pull/119290), [@carlory](https://github.com/carlory))
- Added apiserver identity to the following metrics: 

entsprev","guaranteedUnique","children","contents","prev","sibling","cur","targets","l","closest","index","prevAll","add","addBack","parents","parentsUntil","nextAll","nextUntil","prevUntil","contentDocument","content","reverse","rnothtmlwhite","Identity","v","Thrower","ex","adoptValue","resolve","reject","noValue","method","promise","fail","then","Callbacks","object","_","flag","firing","memory","fired","locked","list","queue","firingIndex","fire","once","stopOnFalse","remove","disable","lock",...

* Uses the port config option in the kubeapi-load-balancer charm. ([#48958](https://github.com/kubernetes/kubernetes/pull/48958), [@wwwtyro](https://github.com/wwwtyro))
* azure: support retrieving access tokens via managed identity extension ([#48854](https://github.com/kubernetes/kubernetes/pull/48854), [@colemickens](https://github.com/colemickens))

* The node authorizer now allows nodes to request service account tokens for the service accounts of pods running on them. This allows agents using the node identity to take actions on behalf of local pods. ([#55019](https://github.com/kubernetes/kubernetes/pull/55019), [@mikedanese](https://github.com/mikedanese))

### SIG Windows development tools

/enhancements/tree/master/keps/sig-storage/596-csi-inline-volumes) feature allows CSI volumes to be specified directly in the pod specification for ephemeral use cases. They can be used to inject arbitrary states, such as configuration, secrets, identity, variables or similar information, directly inside pods using a mounted volume. This was initially introduced in 1.15 as an alpha feature, and it moved to GA. This feature is used by some CSI drivers such as the [secret-store CSI driver](https:/...
