* 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))

- Made legacy watch calls (`ResourceVersion` = 0 or unset) that generate init-events weigh higher in `API Priority and Fairness (APF)` seat usage. Properly accounting for their cost protects the API server from CPU overload. Users might see increased throttling of such calls as a result. ([#134601](https...

### SIG Network

The main milestones for SIG Network this release are the graduation of IPVS-based load balancing and CoreDNS to general availability.

IPVS is an alternative approach to in-cluster load balancing that uses in-kernel hash tables rather than the previous iptables approach, while CoreDNS is a replacement for kube-dns for service discovery.

### SIG Node

* 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))

- `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))

* [fluentd-gcp addon] Switch to the image provided by Stackdriver. The Stackdriver Logging Agent container image uses fluentd v0.14.25. ([#59128](https://github.com/kubernetes/kubernetes/pull/59128), [@bmoyles0117](https://github.com/bmoyles0117))

## Non-user-facing Changes

- 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.

- 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).
