- Registered metric `apiserver_request_body_size_bytes` to track the size distribution of requests by `resource` and `verb`. ([#120474](https://github.com/kubernetes/kubernetes/pull/120474),...

- Fix a bug in cronjob controller where already created jobs...

- Add a `serving` and `terminating` condition to the EndpointSlice API.
  `serving` tracks the readiness of endpoints regardless of their terminating state. This is distinct from `ready` since `ready` is only true when pods are not terminating. 

- The iptables mode of kube-proxy now tracks accepted packets that are destined for node-ports on localhost by introducing `kubeproxy_iptables_localhost_nodeports_accepted_packets_total` metric.

- A new kubelet metric `image_pull_duration_seconds` was added. The metric tracks the duration (in seconds) it takes for an image to be pulled, including the time spent in the waiting queue of image puller. The metric is broken down by bucketed image size.

#### Application Deployment

* DaemonSet, Deployment, ReplicaSet, and StatefulSet objects are now persisted in etcd in apps/v1 format ([#58854](https://github.com/kubernetes/kubernetes/pull/58854), [@liggitt](https://github.com/liggitt))

* YAMLDecoder Read now tracks rest of buffer on io.ErrShortBuffer ([#58817](https://github.com/kubernetes/kubernetes/pull/58817), [@karlhungus](https://github.com/karlhungus))

  // allocatedResources is the storage resource within AllocatedResources tracks the capacity allocated to a PVC. It may
  // be larger than the actual capacity when a volume expansion operation is requested.
  // For storage quota, the larger value from allocatedResources and PVC.spec.resources is used.

### Feature

- A new Priority and Fairness metric 'apiserver_flowcontrol_work_estimate_seats_samples' has been added that tracks the estimated seats associated with a request. ([#106628](https://github.com/kubernetes/kubernetes/pull/106628), [@tkashem](https://github.com/tkashem))
