- A new `DisableCompression` field (default = `false`) has been added to kubeconfig under cluster info. When set to `true`, clients using the kubeconfig opt out of response compression for all requests to the apiserver. This can help improve list call latencies significantly when client-server network bandwidth is ample (>30MB/s) or if the server is CPU-constrained.

- 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. ([#112398](https://github.com/kubernetes/kubernetes/pull/112398),...
