### 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). ([#122757](https://github.com/kubernetes/kubernetes/pull/122757), [@hakman](https://github.com/hakman)) [SIG Network]

- 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

- Improving the performance of Endpoint and EndpointSlice controllers by caching Service Selectors ([#84280](https://github.com/kubernetes/kubernetes/pull/84280), [@gongguan](https://github.com/gongguan))
- Significant kube-proxy performance improvements when using Endpoint Slices at scale. ([#83206](https://github.com/kubernetes/kubernetes/pull/83206), [@robscott](https://github.com/robscott))

* Detach and clear bad disk URI ([#58345](https://github.com/kubernetes/kubernetes/pull/58345), [@rootfs](https://github.com/rootfs))

* Fixed CSIDriver API object to allow missing fields. ([#69331](https://github.com/kubernetes/kubernetes/pull/69331), [@jsafrane](https://github.com/jsafrane))
* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))

- Fix a bug on the endpoint slices mirroring controller where endpoint NotReadyAddresses were mirrored as Ready to the corresponding EndpointSlice ([#102683](https://github.com/kubernetes/kubernetes/pull/102683), [@aojea](https://github.com/aojea)) [SIG Apps and Network]

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop

* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))

* 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))
