- 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. ([#112399](https://github.com/kubernetes/kubernetes/pull/112399), [@shyamjvs]...

Instead the API server will automatically carry these forward from the original object when...
