#### 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]

- The `EndpointSlice` API is now GA. The `EndpointSlice` topology field has been removed from the GA API and will be replaced by a new per Endpoint Zone field. If the topology field was previously used, it will be converted into an annotation in the v1 Resource. The `discovery.k8s.io/v1alpha1`...

- Fix static pod restarts in cases where the container is not present. ([#108189](https://github.com/kubernetes/kubernetes/pull/108189), [@rphillips](https://github.com/rphillips)) [SIG Node]
- Fixes a bug where a partial EndpointSlice update could cause node name information to be dropped from endpoints that were not updated. ([#108202](https://github.com/kubernetes/kubernetes/pull/108202), [@robscott](https://github.com/robscott)) [SIG 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.

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

- EndpointSlice IP validation now matches Endpoints IP validation. ([#101084](https://github.com/kubernetes/kubernetes/pull/101084), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

### 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]
