- jsonpath expressions containing `[start:end:step]` slice are now evaluated correctly ([#73149](https://github.com/kubernetes/kubernetes/pull/73149), [@liggitt](https://github.com/liggitt))

- Implemented deduplication logic for v1beta1.Event API ([#65782](https://github.com/kubernetes/kubernetes/pull/65782), [@yastij](https://github.com/yastij))

* Fixed a bug where a jsonpath filter would return an error if one of the items being evaluated did not contain all of the nested elements in the filter query. ([#47846](https://github.com/kubernetes/kubernetes/pull/47846), [@ncdc](https://github.com/ncdc))

- Kube-apiserver: jsonpath expressions with consecutive recursive descent operators are no longer evaluated for custom resource printer columns ([#93408](https://github.com/kubernetes/kubernetes/pull/93408), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery]

- `GetPodQOS(pod *core.Pod)` function now returns the stored value from `PodStatus.QOSClass`, if set. To compute/evaluate the value of `QOSClass` from scratch, `ComputePodQOS(pod*core.Pod)` must be used. ([#119665](https://github.com/kubernetes/kubernetes/pull/119665), [@vinaykul](https://github.com/vinaykul))

- Fixed a bug in CEL's common.UnstructuredToVal where `==` evaluates to false for identical objects when a field is present but the value is null.  This bug does not impact the Kubernetes API. ([#131559](https://github.com/kubernetes/kubernetes/pull/131559), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]...

  
  However, the Job controller creates a replacement Pod as soon as the termination becomes apparent.
  Once the pod terminates, the Job controller evaluates `.backoffLimit` and `.podFailurePolicy` for the
  relevant Job, taking this now-terminated Pod into consideration.
  
  This behavior is limited to Jobs with `.spec.podFailurePolicy` set, and only when those two feature
