* Add garbage collector into kube-controller-manager ([#26341](https://github.com/kubernetes/kubernetes/pull/26341), [@caesarxuchao](https://github.com/caesarxuchao))
* Add orphaning finalizer logic to GC ([#25599](https://github.com/kubernetes/kubernetes/pull/25599), [@caesarxuchao](https://github.com/caesarxuchao))

- Fixes a bug where Services using finalizers may hold onto ClusterIP and/or NodePort allocated resources for longer than expected if the finalizer is removed using the status subresource ([#120657](https://github.com/kubernetes/kubernetes/pull/120657), [@aojea](https://github.com/aojea)) [SIG Network and Testing]

* Fixed controller manager crash by making it tolerant to discovery errors.([#49767](https://github.com/kubernetes/kubernetes/pull/49767), [@deads2k](https://github.com/deads2k))

- Fix job tracking with finalizers for more than 500 pods, ensuring all finalizers are removed before counting the Pod. ([#104666](https://github.com/kubernetes/kubernetes/pull/104666), [@alculquicondor](https://github.com/alculquicondor))

* Fixes potential deadlock when deleting CustomResourceDefinition for custom resources with finalizers ([#60542](https://github.com/kubernetes/kubernetes/pull/60542), [@liggitt](https://github.com/liggitt))

* Fixed potential deadlock when deleting CustomResourceDefinition for custom resources with finalizers. ([#60542](https://github.com/kubernetes/kubernetes/pull/60542), [@liggitt](https://github.com/liggitt))

* The OwnerReferencesPermissionEnforcement admission plugin now requires `update` permission on the `finalizers` subresource of the referenced owner in order to set `blockOwnerDeletion` on an owner reference.

* Fix for [failure to delete federation controllers with finalizers](https://github.com/kubernetes/kubernetes/issues/43828). ([#44084](https://github.com/kubernetes/kubernetes/pull/44084), [@nikhiljindal](https://github.com/nikhiljindal))

### Failing Test

- Resolves an issue running Ingress conformance tests on clusters which use finalizers on Ingress objects to manage releasing load balancer resources ([#96742](https://github.com/kubernetes/kubernetes/pull/96742), [@spencerhance](https://github.com/spencerhance)) [SIG Network and Testing]
