* Fix regression in `v1.JobSpec.backoffLimit` that caused failed Jobs to be restarted indefinitely. ([#63650](https://github.com/kubernetes/kubernetes/pull/63650), [@soltysh](https://github.com/soltysh))

- Fixed a bug in the garbage collector controller which could block indefinitely due to a cache sync failure. This fix allows the garbage collector to eventually continue garbage collecting other resources if a given resource cannot be listed or watched. Any objects in the unsynced resource type with owner references with ...

* fixed foreground deletion of podtemplates ([#60683](https://github.com/kubernetes/kubernetes/pull/60683), [@nilebox](https://github.com/nilebox))
* Timeout docker queries to prevent node going NotReady indefinitely. ([#56967](https://github.com/kubernetes/kubernetes/pull/56967), [@jsravn](https://github.com/jsravn))

* Fix erroneous FailedSync and FailedMount events being periodically and indefinitely posted on Pods after kubelet is restarted ([#44781](https://github.com/kubernetes/kubernetes/pull/44781), [@wongma7](https://github.com/wongma7))

- kubeadm now can join the cluster with pre-existing client certificate if provided ([#66482](https://github.com/kubernetes/kubernetes/pull/66482), [@dixudx](https://github.com/dixudx))
- kubeadm will no longer hang indefinitely if there is no Internet connection and --kubernetes-version is not specified.([#65676](https://github.com/kubernetes/kubernetes/pull/65676), [@dkoshkin](https://github.com/dkoshkin))
