### Bug or Regression

- Added jitter factor to lease controller that better smears load on kube-apiserver over time. ([#101652](https://github.com/kubernetes/kubernetes/pull/101652), [@marseel](https://github.com/marseel)) [SIG API Machinery and Scalability]

  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 
  But, registering appropriate `QueueingHintFn` is, of course, better from a scheduling performance perspective. ([#118551](https://github.com/kubernetes/kubernetes/pull/118551), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling, Storage and Testing]

* update QEMU version to v2.9.1 ([#50597](https://github.com/kubernetes/kubernetes/pull/50597), [@dixudx](https://github.com/dixudx))
* controllers backoff better in face of quota denial ([#49142](https://github.com/kubernetes/kubernetes/pull/49142), [@joelsmith](https://github.com/joelsmith))

seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.

To learn more about the feature, please refer to the official [seccomp tutorial](https://kubernetes.io/docs/tutorials/clusters/seccomp/#enable-the-use-of-runtimedefault-as-...

### Other (Cleanup or Flake)

- Service session affinity timeout tests are no longer required for Kubernetes network plugin conformance due to variations in existing implementations. New conformance tests will be developed to better express conformance in future releases.

### Added

- All `klog` flags except for `-v` and `-vmodule` are deprecated. Support for `-vmodule` is only guaranteed for the text log format. ([#105042](https://github.com/kubernetes/kubernetes/pull/105042), [@pohly](https://github.com/pohly))

- kubeadm: Added better handling of errors during unmount when calling `kubeadm reset`. When failing to unmount directories under `/var/run/kubelet`, kubeadm will now throw an error instead of showing a warning and continuing to clean up said directory. In such situations, it is better for you to inspect the problem and resolve it manually. Then, you can call `kubeadm reset` again to complete the cleanup....

  you want to set the equivalent of any of the `--iptables-xxx` options.)
  
  As this code is still very new, it has not been heavily optimized yet;
  while it is expected to _eventually_ have better performance than the
  iptables backend, very little performance testing has been done so far. ([#121046](https://github.com/kubernetes/kubernetes/pull/121046), [@danwinship](https://github.com/danwinship))
