- Failed pods associated with a job with `parallelism = 1` are recreated by the job controller honoring exponential backoff delay again. However, for jobs with `parallelism > 1`, pods might be created without exponential backoff delay.

### Cluster Federation

#### [alpha] Federated Jobs

Federated Jobs that are automatically deployed to multiple clusters
are now supported. Cluster selection and weighting determine how Job
parallelism and completions are spread across clusters. Federated Job
status reflects the aggregate status across all underlying cluster
jobs.

#### [alpha] Federated Horizontal Pod Autoscaling (HPA)

* Create a new Deployment in kube-system for every version. ([#23512](https://github.com/kubernetes/kubernetes/pull/23512), [@Q-Lee](https://github.com/Q-Lee))
* Use SCP to dump logs and parallelize a bit. ([#22835](https://github.com/kubernetes/kubernetes/pull/22835), [@spxtr](https://github.com/spxtr))

* AWS kube-down: Issue warning if VPC not found ([#27518](https://github.com/kubernetes/kubernetes/pull/27518), [@justinsb](https://github.com/justinsb))
* gce/kube-down: Parallelize IGM deletion, batch more ([#27302](https://github.com/kubernetes/kubernetes/pull/27302), [@zmerlynn](https://github.com/zmerlynn))

* Replace Parallelize with function ParallelizeUntil and formally deprecate the Parallelize. ([#68403](https://github.com/kubernetes/kubernetes/pull/68403), [@wgliang](https://github.com/wgliang))

- Removed the function Parallelize, please convert to use the function ParallelizeUntil. ([#76595](https://github.com/kubernetes/kubernetes/pull/76595), [@danielqsj](https://github.com/danielqsj))

### Apps

### Feature

- Parallelize calls to conversion webhooks when watching from etcd to prevent watchcache from lagging and helps clusters with slow conversion webhooks or transformers.
