* Job controller now respects ControllerRef to avoid fighting over Pods. ([#42176](https://github.com/kubernetes/kubernetes/pull/42176), [@enisoc](https://github.com/enisoc))

* CronJob controller now respects ControllerRef to avoid fighting with other controllers. ([#42177](https://github.com/kubernetes/kubernetes/pull/42177), [@enisoc](https://github.com/enisoc))

- Avoid caching the Azure VMSS instances whose network profile is nil ([#100948](https://github.com/kubernetes/kubernetes/pull/100948), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

    * Default value for expendable pod priority cutoff in GCP deployment of Cluster Autoscaler changed from 0 to -10.
    * action required: users deploying workloads with priority lower than 0 may want to use priority lower than -10 to avoid triggering scale-up.

### Other notable changes

* Metadata Agent Improvements ([#66485](https://github.com/kubernetes/kubernetes/pull/66485), [@bmoyles0117](https://github.com/bmoyles0117))

Anyway, the cluster should get back to the proper size after 10 min.

### Deployment

- DaemonSet controller is now using backoff algorithm to avoid hot loops fighting with kubelet on pod recreation when a particular DaemonSet is misconfigured. ([#65309](https://github.com/kubernetes/kubernetes/pull/65309), [@tnozicka](https://github.com/tnozicka))
