- The test "[sig-network] EndpointSlice should have Endpoints and EndpointSlices pointing to API Server [Conformance]" only requires that there is an EndpointSlice that references the "kubernetes.default" service, it no longer requires that its named "kubernetes". ([#104664](https://github.com/kubernetes/kubernetes/pull/104664), [@aojea](https...

- Improved performance of `Endpoint` and `EndpointSlice` controllers when there are a large number of services in a single namespace by making pod-to-service lookup asynchronous.

## Changes by Kind

### Deprecation

  the endpoints for it by hand (rather than letting kube-controller-manager
  generate `Endpoints` and `EndpointSlices` for it automatically based on the
  Service definition), then you should write out an EndpointSlice object rather
  than (or in addition to) an `Endpoints` object. ([#129837](https://github.com/kubernetes/kubernetes/pull/129837), [@danwinship](https://github.com/danwinship)) [SIG API Machinery, Network and Testing]

- Adds EndpointSlice integration to kube-proxy, can be enabled with EndpointSlice feature gate. ([#81430](https://github.com/kubernetes/kubernetes/pull/81430), [@robscott](https://github.com/robscott))

- Fix printing resources with int64 fields ([#110572](https://github.com/kubernetes/kubernetes/pull/110572), [@sanchezl](https://github.com/sanchezl)) [SIG API Machinery]
- Fix unnecessary recreation of placeholder EndpointSlice ([#110732](https://github.com/kubernetes/kubernetes/pull/110732), [@jluhrsen](https://github.com/jluhrsen)) [SIG Apps and Network]

- Fixed a bug on the `EndpointSlice` mirroring controller that generated multiple slices in some cases for custom endpoints in non canonical format. ([#114155](https://github.com/kubernetes/kubernetes/pull/114155), [@aojea](https://github.com/aojea))

### Documentation

- Migrated the `EndpointSlice` and `EndpointSliceMirroring` controllers (within `kube-controller-manager`) to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging). ([#115295](https://github.com/kubernetes/kubernetes/pull/115295),...

  even when the deprecated annotation `volume.beta.kubernetes.io/storage-class` was set. ([#116089](https://github.com/kubernetes/kubernetes/pull/116089), [@cvvz](https://github.com/cvvz)) [SIG Apps and Storage]
