- Adds a /flagz endpoint for kube-scheduler endpoint ([#128818](https://github.com/kubernetes/kubernetes/pull/128818), [@yongruilin](https://github.com/yongruilin)) [SIG Architecture, Instrumentation, Scheduling and Testing]

  Provided you enable the `KubeletFineGrainedAuthz` feature gate, you can access kubelet's `/healthz` endpoint by granting the caller `nodes/helathz` permission in RBAC.
  Similarly you can also access  kubelet's `/pods` endpoint to fetch a list of Pods bound to that node by granting the caller `nodes/pods` permission in RBAC.

- resource metrics endpoint `/metrics/resource/v1alpha1` as well as all metrics under this endpoint have been deprecated. Please convert to the following metrics emitted by endpoint `/metrics/resource`:
  - scrape_error --> scrape_error
  - node_cpu_usage_seconds_total --> node_cpu_usage_seconds

- EndpointSlice hostname is now set in the same conditions Endpoints hostname is. ([#84207](https://github.com/kubernetes/kubernetes/pull/84207), [@robscott](https://github.com/robscott))

### Bug or Regression

- Fixes a race condition in the iptables mode of kube-proxy in 1.27 and later
  that could result in some updates getting lost (e.g., when a service gets a
  new endpoint, the rules for the new endpoint might not be added until
  much later). ([#122815](https://github.com/kubernetes/kubernetes/pull/122815), [@wedaly](https://github.com/wedaly)) [SIG Network]

- Endpoint controller requeues service after an endpoint deletion event occurs to confirm that deleted endpoints are undesired to mitigate the effects of an out of sync endpoint cache. ([#93030](https://github.com/kubernetes/kubernetes/pull/93030), [@swetharepakula](https://github.com/swetharepakula)) [SIG Apps and Network]

      endpoint now gets broken when that endpoint becomes non-ready
      (rather than continuing until the endpoint is fully deleted).
  
    - 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

- 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]

- Fixing issue with Winkernel Proxier - No ingress load balancer rules with endpoints to support load balancing when all the endpoints are terminating. ([#114451](https://github.com/kubernetes/kubernetes/pull/114451),...
