- `kubectl proxy` now correctly handles the `exec`, `attach`, and
  `portforward` commands.  You must pass `--disable-filter` to the command to allow these commands.

- Added `cronjobs.batch` to "all", so that `kubectl get all` returns them.

- Added flag `--include-uninitialized` to `kubectl annotate`, `apply`, `edit-last-applied`,

- Dropped the additional rule requirement (cronjobs/finalizers) for roles
  using kubectl create cronjobs to ensure backward compatibility. ([#124883](https://github.com/kubernetes/kubernetes/pull/124883), [@ardaguclu](https://github.com/ardaguclu))

- Promote CronJobs to batch/v1 ([#99423](https://github.com/kubernetes/kubernetes/pull/99423), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, Apps, CLI and Testing]

* Set defaults for successfulJobsHistoryLimit (3) and failedJobsHistoryLimit (1) in batch/v1beta1.CronJobs ([#52533](https://github.com/kubernetes/kubernetes/pull/52533), [@soltysh](https://github.com/soltysh))

* Scheduler only activates unschedulable pods if node's scheduling related properties change. ([#71551](https://github.com/kubernetes/kubernetes/pull/71551), [@mlmhl](https://github.com/mlmhl))
* Fixes pod deletion when cleaning old cronjobs ([#71802](https://github.com/kubernetes/kubernetes/pull/71802), [@soltysh](https://github.com/soltysh))

### CLI

- Fixed `kubectl exec` usage string to correctly reflect flag placement. ([#77589](https://github.com/kubernetes/kubernetes/pull/77589), [@soltysh](https://github.com/soltysh))
- Fixed `kubectl describe cronjobs` error of `Successful Job History Limit`. ([#77347](https://github.com/kubernetes/kubernetes/pull/77347), [@danielqsj](https://github.com/danielqsj))

## Changelog since v1.5.0-alpha.2

### Action Required

* Deprecate extensions/v1beta1.Jobs ([#36355](https://github.com/kubernetes/kubernetes/pull/36355), [@soltysh](https://github.com/soltysh))
* Rename ScheduledJobs to CronJobs. ([#36021](https://github.com/kubernetes/kubernetes/pull/36021), [@soltysh](https://github.com/soltysh))

- Drop additional rule requirement (cronjobs/finalizers) in the roles who use kubectl create cronjobs to be backwards compatible ([#124883](https://github.com/kubernetes/kubernetes/pull/124883), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI]

- Annotation `batch.kubernetes.io/cronjob-scheduled-timestamp` added to Job objects scheduled from CronJobs is promoted to stable. ([#128336](https://github.com/kubernetes/kubernetes/pull/128336), [@soltysh](https://github.com/soltysh))

- Added warnings about workload resources (Pods, ReplicaSets, Deployments, Jobs, CronJobs, or ReplicationControllers) whose names are not valid DNS labels. ([#114412](https://github.com/kubernetes/kubernetes/pull/114412), [@thockin](https://github.com/thockin))
