a replicaset becomes asynchronous by default. The object will continue to exist in the key-value store for some time. The API server will set its metadata.deletionTimestamp, add the "orphan" finalizer to its metadata.finalizers. The object will be deleted from the key-value store after the garbage collector orphans its dependents. Please refer to this [user-guide](http://kubernetes.io/docs/user-guide/garbage-collector/) for more information regarding the garbage collection.

* **Other objects**:...

- Garbage collector now can correctly orphan ControllerRevisions when StatefulSets are deleted with orphan propagation policy. ([#84984](https://github.com/kubernetes/kubernetes/pull/84984), [@cofyc](https://github.com/cofyc)) [SIG Apps]

* Fixes an issue with stuck connections handling error responses ([#71419](https://github.com/kubernetes/kubernetes/pull/71419), [@liggitt](https://github.com/liggitt))
* Ensure orphan public IPs on Azure deleted when service recreated with the same name. ([#70463](https://github.com/kubernetes/kubernetes/pull/70463), [@feiskyer](https://github.com/feiskyer))

### SIG Azure

- Ensured orphan public IPs on Azure deleted when service recreated with the same name. ([#70463](https://github.com/kubernetes/kubernetes/pull/70463), [@feiskyer](https://github.com/feiskyer))

### Bug or Regression

- Only declare Job as finished after removing all Pod finalizers to avoid orphan Pods ([#119165](https://github.com/kubernetes/kubernetes/pull/119165), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps and Testing]

- Enabled kube-controller-manager '--concurrent-job-syncs' flag works on orphan Pod processors ([#126567](https://github.com/kubernetes/kubernetes/pull/126567), [@fusida](https://github.com/fusida)) [SIG Apps]

- Declare Job as finished only after removing all Pod finalizers to avoid orphan Pods. ([#119159](https://github.com/kubernetes/kubernetes/pull/119159), [@alculquicondor](https://github.com/alculquicondor))

- Add foreground cascading deletion to kubectl with the new `kubectl delete foreground|background|orphan` option. ([#93384](https://github.com/kubernetes/kubernetes/pull/93384), [@zhouya0](https://github.com/zhouya0))
