### Other notable changes

* When the number of jobs exceeds 500, cronjob should schedule without error. ([#77475](https://github.com/kubernetes/kubernetes/pull/77475), [@liucimin](https://github.com/liucimin))

- Adds two new metrics to cronjobs, a histogram to track the time difference when a job is created and the expected time when it should be created, as well as a gauge for the missed schedules of a cronjob ([#99341](https://github.com/kubernetes/kubernetes/pull/99341), [@alaypatel07](https://github.com/alaypatel07))

- Fixes calculating the requeue time in the cronjob controller, which results in properly handling failed/stuck jobs ([#121540](https://github.com/kubernetes/kubernetes/pull/121540), [@soltysh](https://github.com/soltysh)) [SIG Apps]

- Users should not rely on unsupported CRON_TZ variable when specifying schedule, both the API server and cronjob controller will emit warnings pointing to https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/ containing explanation ([#106455](https://github.com/kubernetes/kubernetes/pull/106455), [@soltysh](https://github.com/soltysh)) [SIG Apps]...

  * You do not need to adjust this flag on Kubelet:  there was no authorization for the Kubelet APIs in 1.4.
* batch/v2alpha1.ScheduledJob has been renamed, use batch/v2alpha1.CronJob instead ([#36021](https://github.com/kubernetes/kubernetes/pull/36021), [@soltysh](https://github.com/soltysh))
* PetSet has been renamed to StatefulSet.
  If you have existing PetSets, **you must perform extra migration steps** both
