#### Network
- EndpointSlices: If upgrading a cluster with EndpointSlices already enabled, any EndpointSlices that should be managed by the EndpointSlice controller should have a `endpointslice.kubernetes.io/managed-by` label set to `endpointslice-controller.k8s.io`.

#### Scheduling

- The EndpointSlice controller now waits for EndpointSlice and Node caches to be synced before starting. ([#94086](https://github.com/kubernetes/kubernetes/pull/94086), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- EndpointSlice has a new NodeName field guarded by the EndpointSliceNodeName feature gate.
  - EndpointSlice topology field will be deprecated in an upcoming release.
  - EndpointSlice "IP" address type is formally removed after being deprecated in Kubernetes 1.17.

### Failing Test

- Fixes hostpath storage e2e tests within SELinux enabled env (#105786, @Elbehery) [SIG Testing]

### Bug or Regression

- EndpointSlice Mirroring controller now cleans up managed EndpointSlices when a Service selector is added (#106132, @robscott) [SIG Apps, Network and Testing]

- 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".

### EndpointSlices are now enabled by default

EndpointSlices are an exciting new API that provides a scalable and extensible alternative to the Endpoints API. EndpointSlices track IP addresses, ports, readiness, and topology information for Pods backing a Service.

- 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. ([#134739](https://github.com/kubernetes/kubernetes/pull/134739), [@shyamjvs](https://github.com/shyamjvs)) [SIG Apps and...

- 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))

- Endpoints and EndpointSlice controllers no longer populate [resourceVersion of targetRef](https://kubernetes.io/docs/reference/kubernetes-api/common-definitions/object-reference/#ObjectReference) in Endpoints and EndpointSlices ([#108450](https://github.com/kubernetes/kubernetes/pull/108450), [@tnqn](https://github.com/tnqn))
