* kubelet: fix fail to close kubelet->API connections on heartbeat failure when bootstrapping or client certificate rotation is disabled ([#78016](https://github.com/kubernetes/kubernetes/pull/78016), [@gaorong](https://github.com/gaorong))
* Active watches of custom resources now terminate properly if the CRD is modified. ([#78029](https://github.com/kubernetes/kubernetes/pull/78029), [@liggitt](https://github.com/liggitt))

### DELETE operation in REST API

* The kubelet --reconcile-cdir flag is deprecated because it has no function anymore. ([#35523](https://github.com/kubernetes/kubernetes/pull/35523), [@luxas](https://github.com/luxas))
* Notice of deprecation for recycler [#36760](https://github.com/kubernetes/kubernetes/pull/36760)

### Other (Cleanup or Flake)

- Fix: statle smb mount issue when smb file share is deleted and then unmount ([#121851](https://github.com/kubernetes/kubernetes/pull/121851), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]
- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.

- Set kubelet option `--volume-stats-agg-period` to negative value to disable volume calculations. ([#96675](https://github.com/kubernetes/kubernetes/pull/96675), [@pacoxu](https://github.com/pacoxu)) [SIG Node]

### Failing Test

- Kubelet podresources API now provides the information about active pods only. ([#79409](https://github.com/kubernetes/kubernetes/pull/79409), [@takmatsu](https://github.com/takmatsu)) [SIG Node]
