<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...

- Introduced API type `coordination.k8s.io/v1beta1/LeaseCandidate`
  `CoordinatedLeaderElection` feature moves to Beta ([#130751](https://github.com/kubernetes/kubernetes/pull/130751), [@Jefftree](https://github.com/Jefftree)) [SIG API Machinery, Etcd and Testing]

- Types: Code and Status moved from pkg/scheduler/framework to staging repo.
  Users should update import path for these types from `k8s.io/kubernetes/pkg/scheduler/framework` to `k8s.io/kube-scheduler/framework`. ([#132087](https://github.com/kubernetes/kubernetes/pull/132087), [@ania-borowiec](https://github.com/ania-borowiec)) [SIG Node, Scheduling, Storage and Testing]

- Services implemented a field selector for the ClusterIP and Type fields.
  The Kubelet uses this field selector to avoid monitoring Headless Services, which helps reduce memory consumption. ([#123905](https://github.com/kubernetes/kubernetes/pull/123905), [@aojea](https://github.com/aojea)) [SIG Apps, Node and Testing]

  
  ### GCE
  - Decrease the number of GCE Read Requests made while deleting nodes
  - Base pricing of custom instances on their instance family type
  - 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

* 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':
