* The `emptyDir.sizeLimit` field is now correctly omitted from API requests and responses when unset. ([#50163](https://github.com/kubernetes/kubernetes/pull/50163), [@jingxu97](https://github.com/jingxu97))

- Added support for specifying `controlplane` or `cluster` egress selectors in JWT authenticators via the `issuer.egressSelectorType` field in the `AuthenticationConfiguration.jwt` array. If unset, the previous behavior of using no egress selector is preserved. This functionality requires the `StructuredAuthenticationConfigurationEgressSelector` beta feature gate (enabled by default).

#### Storage

- The `Node.Status.Volumes.Attached.DevicePath` field is now unset for CSI volumes. You must update any external controllers that depend on this field. ([#75799](https://github.com/kubernetes/kubernetes/pull/75799), [@msau42](https://github.com/msau42))

- Tighten validation on the qosClass field of pod status. This field is immutable but it would be populated with the old status by kube-apiserver if it is unset in the new status when updating this field via the status subsource. ([#127744](https://github.com/kubernetes/kubernetes/pull/127744), [@carlory](https://github.com/carlory)) [SIG Apps, Instrumentation, Node, Storage and Testing]

- `Service` of type `ExternalName` do not create an `Endpoint` anymore. ([#114814](https://github.com/kubernetes/kubernetes/pull/114814), [@panslava](https://github.com/panslava))
- `cacher`: If `ResourceVersion` is unset, the watch is now served from the underlying storage as documented. ([#115096](https://github.com/kubernetes/kubernetes/pull/115096), [@MadhavJivrajani](https://github.com/MadhavJivrajani))

- Added audienceMatchPolicy field to AuthenticationConfiguration and support for configuring multiple audiences.
  The "audienceMatchPolicy" can be empty (or unset) when a single audience is specified in the "audiences" field.

this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is *estimating* the size...
