type of a specially annotated switch expression.
The switch expression is evaluated exactly once in a switch statement.

<h4 id="Expression_switches">Expression switches</h4>

<p>
In an expression switch,
the switch expression is evaluated and
the case expressions, which need not be constants,
are evaluated left-to-right and top-to-bottom; the first one that equals the
switch expression

- `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.

- 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))

  // Parameters specified here will be merged to the generated DNS
  // configuration based on DNSPolicy.
  // +optional
  optional PodDNSConfig dnsConfig = 26;

  // If specified, all readiness gates will be evaluated for pod readiness.
  // A pod is ready when all its containers are ready AND
  // all conditions specified in the readiness gates have status equal to "True"

* 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))

  
  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
