- A new `pod_status_sync_duration_seconds` histogram is reported at alpha metrics stability that estimates how long the Kubelet takes to write a pod status change once it is detected.

- kubeadm: You can now delete multiple bootstrap tokens at once. ([#75646](https://github.com/kubernetes/kubernetes/pull/75646), [@bart0sh](https://github.com/bart0sh))

- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI NodeStageVolume for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This PR ensures it is only called once per volume per node. ([#112403](https://github.com/kubernetes/kubernetes/pull/112403), [@akankshakumari393](https://github.com/akankshakumari393)) [SIG Storage]

- Added the implementation for `PodRecreationPolicy` to wait for the creation of pods once the existing ones are fully terminated. ([#117015](https://github.com/kubernetes/kubernetes/pull/117015), [@kannon92](https://github.com/kannon92))

  - the `--cloud-provider-gce-lb-src-cidrs` flag has been deprecated. This flag will be removed once the GCE Cloud Provider is removed from kube-apiserver. ([#81094](https://github.com/kubernetes/kubernetes/pull/81094), [@andrewsykim](https://github.com/andrewsykim))

- In the `wait.PollUntilContextTimeout` function, if `immediate` is true, the condition will now be invoked before waiting, guaranteeing that the condition is invoked at least once and then wait a interval before executing again.

- Client-go: fix that paged list calls with ResourceVersionMatch set would fail once paging kicked in. ([#107335](https://github.com/kubernetes/kubernetes/pull/107335), [@fasaxc](https://github.com/fasaxc)) [SIG API Machinery]

  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric

- `batch/v2alpha1.ScheduledJob` is removed.

- The Job controller now creates pods in batches instead of all at once. ([#49142](https://github.com/kubernetes/kubernetes/pull/49142), [@joelsmith](https://github.com/joelsmith)).
