Kubernetes: Scheduler Gang Cleanup, Proxy and User Namespace Backports

Scheduler work dominates with gang-scheduling cleanup and clearer status and metrics, while kubectl proxy CSRF and kubelet user-namespace fixes are being backported to 1.35 through 1.37. Control-plane consistency work aligns cache and etcd watches and tightens CRD and in-place resize admission.

Good morning, it's October 20th, 2026 — this is your Kubernetes developer briefing.

The clearest pattern today is scheduler maturation around gang scheduling and workload-aware placement, with cleaner internals and clearer signals for operators.

First theme: gang scheduling cleanup. PR 142951 removed group priority lookups and special-case forks in preemption, relying on uniform priority and snapshot listers instead, with commit c905fdd landing that change. Related follow-up 143209 moves hierarchy traversal into a shared helper with explicit error handling…

Second: security and node fixes moving to stable branches. The kubectl proxy cross-site filter extension, merged as 143187 and cherry-picked as 143189 through 143191 to releases 1.35 to 1.37, blocks the node run API path from leaking administrative ports. Separately, the user namespace ID-range fix from 141345 is…

Third: control-plane consistency. PR 143092 aligns non-recursive watch behavior between the cache layer and etcd, while 143166 refactors etcd storage helpers, and 143199 re-checks custom resource name conflicts that were skipped as already accepted. For in-place pod resize, proposal 143202 would make admission…
