Kubernetes: The Great Feature Gate Cleanup

A wave of pull requests removed long-graduated feature gates across networking, scheduling, apps, and instrumentation, while the scheduler subsystem saw a cluster of concurrency and correctness fixes. Together they mark routine but essential release hygiene ahead of version 1.38.

Good morning, it's September 1st, 2026, and this is your Kubernetes briefing.

Today's biggest signal is cleanup. Across at least five pull requests, contributors are removing feature gates that graduated to general availability years ago and were simply never cleared out. Dan Winship's PR 141733 removes old networking gates including "N-Ftables Proxy Mode" and the multi-C-I-D-R service…

The second theme is scheduler reliability. Multiple PRs from Macsko and others tightened up the scheduling queue: PR 141575 runs pre-enqueue checks per entity, PR 141546 modernizes iteration with Go's newer iterator pattern, and PR 141695 fixes a data race in requeue logic that was causing test flakiness. A related…

Worth flagging individually: PR 141302 fixes H-P-A replica calculations to properly ignore succeeded pods, preventing incorrect scale-damping in batch-style workloads. And PR 141722 stops kubelet from logging raw H-T-T-P probe headers, closing a credential-leak risk in verbose logs.

What's next: expect the remaining feature-gate removal PRs to merge before code freeze, and watch whether the two mutation-cache race fixes converge into one. Scheduler queue behavior is getting real scrutiny…
