- Fixed 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. ([#120623](https://github.com/kubernetes/kubernetes/pull/120623), [@aojea](https://github.com/aojea))

- Only declare Job as finished after removing all Pod finalizers to avoid orphan Pods ([#119160](https://github.com/kubernetes/kubernetes/pull/119160), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps and Testing]

Ao invés disso, sendo um sistema "assíncrono", uma vez finalizada, a tarefa pode esperar um pouco (alguns microssegundos) para que o computador / programa finalize o que quer que esteja fazendo,e então volte para pegar o resultado e continue trabalhando com ele.

- Do not remove the "batch.kubernetes.io/job-tracking" finalizer from a Pod, in a corner
  case scenario, when the Pod is controlled by an API object which is not a batch Job
  (e.g. when the Pod is controlled by a custom CRD). ([#124798](https://github.com/kubernetes/kubernetes/pull/124798), [@mimowo](https://github.com/mimowo)) [SIG Apps and Testing]
- Dropped the additional rule requirement (cronjobs/finalizers) for roles
