- One new field "InternalTrafficPolicy" in Service is added.
  It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only.
  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

  If you were using the aggregated API server feature, and you were writing out
  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

  - Deletion of remote endpoints will be triggered only for terminated endpoints (those present in the old endpoints map but not in the new endpoints map), whereas previously it was also done for terminating endpoints.

* Update defaultbackend to 1.5: move /metrics to a private endpoint (:10254). ([#69383](https://github.com/kubernetes/kubernetes/pull/69383), [@bowei](https://github.com/bowei))
* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))

- Fix a bug on the endpoints controller that does not reconcile the Endpoint object after this is truncated (it gets more than 1000 endpoints addresses) ([#127417](https://github.com/kubernetes/kubernetes/pull/127417), [@aojea](https://github.com/aojea)) [SIG Apps, Network and Testing]

* Format-separated endpoints for the OpenAPI spec, such as /swagger.json, /swagger-2.0.0.0.json, and so on, have been deprecated. The old endpoints will remain in 1.10, 1.11, 1.12 and 1.13, and get removed in 1.14. Please use single `/openapi/v2` endpoint with the appropriate Accept: header instead. For example:

<table>
  <tr>

- Add Endpoint Slice Controller for managing new EndpointSlice resource, disabled by default. ([#81048](https://github.com/kubernetes/kubernetes/pull/81048), [@robscott](https://github.com/robscott))

      endpoint now gets broken when that endpoint becomes non-ready

    - Traffic to a service IP now starts getting rejected (as opposed to
      merely dropped) as soon as there are no longer any *usable*
      endpoints, rather than waiting until all of the terminating
      endpoints have terminated even when those terminating endpoints
