<p>
A type determines a set of values together with operations and methods specific
to those values. A type may be denoted by a <i>type name</i>, if it has one, which must be
followed by <a href="#Instantiations">type arguments</a> if the type is generic.
A type may also be specified using a <i>type literal</i>, which composes a type
from existing types.

- Kubernetes API Go types removed runtime use of the `github.com/gogo/protobuf` library, and are no longer registered into the global gogo type registry. Kubernetes API Go types were not suitable for use with the `google.golang.org/protobuf` library, and no longer implement `ProtoMessage()` by default to avoid accidental incompatible use. If removal...

* Added bool type support for jsonpath. ([#39063](https://github.com/kubernetes/kubernetes/pull/39063), [@xingzhou](https://github.com/xingzhou))

to Ingress: A new `pathType` field and a new `IngressClass` resource. The `pathType` field allows specifying how paths should be matched. In addition to the default `ImplementationSpecific` type, there are new `Exact` and `Prefix` path types. 

The `IngressClass` resource is used to describe a type of Ingress within a Kubernetes cluster. Ingresses can specify the class they are associated with by using a new `ingressClassName` field on Ingresses. This new resource and field replace the...

## API Changes
- CustomResourceDefinitions now validate documented API semantics of `x-kubernetes-list-type` and `x-kubernetes-map-type` atomic to reject non-atomic sub-types. ([#84722](https://github.com/kubernetes/kubernetes/pull/84722), [@sttts](https://github.com/sttts))

    * If the serialization type is application/vnd.kubernetes.protobuf, and protobuf marshaling is not implemented for the requested API resource type, a '406 Not Acceptable is returned'.
    * If the serialization type is 'application/json':

### Deprecated/changed metrics

- kubelet probe metrics are now of the counter type rather than the gauge type, and the `prober_probe_result` has been replaced by `prober_probe_total`. ([#76074](https://github.com/kubernetes/kubernetes/pull/76074), [@danielqsj](https://github.com/danielqsj))

  `sync_partial_proxy_rules_duration_seconds` (in addition to the existing\n`sync_proxy_rules_duration_seconds`),
  giving better information about the duration of each \nsync type, rather than
  only giving a weighted average of the two sync types together. ([#117787](https://github.com/kubernetes/kubernetes/pull/117787), [@danwinship](https://github.com/danwinship))
- `kubeadm`: added a new "kubeadm config validate" command that can be used to

  
  ### GCE

  - Add pricing information for missing machine types
  - Add pricing information for different GPU types
  - Ignore the new `topology.gke.io/zone` label when comparing groups
  - Add missing stable labels to template nodes

### CVE-2022-3162: Unauthorized read of Custom Resources
