- A new `pod_status_sync_duration_seconds` histogram is reported at alpha metrics...

- kube-proxy uses field-selector clusterIP!=None on Services to avoid watching for Headless Services, reducing unnecessary network bandwidth ([#126769](https://github.com/kubernetes/kubernetes/pull/126769), [@Sakuralbj](https://github.com/Sakuralbj)) [SIG Network]

- Traffic shaping is now supported for the CNI network driver. ([#63194](https://github.com/kubernetes/kubernetes/pull/63194), [@m1093782566](https://github.com/m1093782566))

### Bug or Regression

* Kubernetes client users may disable automatic compression when invoking Kubernetes APIs by setting the `DisableCompression` field on their rest.Config.  This is recommended when clients communicate primarily over high bandwidth / low latency networks where response compression does not improve end to end latency.

### Bug or Regression

- Kube-apiserver: gzip compression switched from level 4 to level 1 to improve large list call latencies in exchange for higher network bandwidth usage (10-50% higher). This increases the headroom before very large unpaged list calls exceed request timeout limits.
