### API Change

- Fixed: log timestamps now include trailing zeros to maintain a fixed width ([#91207](https://github.com/kubernetes/kubernetes/pull/91207), [@iamchuckss](https://github.com/iamchuckss)) [SIG Apps and Node]

### Bug or Regression

    * To avoid that negative effect only use per pod metrics from pods that are:
    * - ready (so metrics about them should be valid), or
    * - unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).

- Added new annotation `batch.kubernetes.io/cronjob-scheduled-timestamp` to Job objects scheduled from CronJobs. ([#118137](https://github.com/kubernetes/kubernetes/pull/118137), [@helayoty](https://github.com/helayoty))
