Good morning, it's November 2nd, 2026.
The big signal today is a concentrated reliability push on the API server watch cache, paired with tighter rules for workload-aware scheduling.
First, the watch cache. PR 143077 merged a fix for a watcher goroutine leak where a stopped watch could block forever if draining was turned on after it was queued for shutdown. That is now preserved correctly. Around it, a series of proposals advances consistency and recovery: PR 143696 introduces Consistent Get…
Second, scheduling. PR 143695 would require all pod group templates in a Workload to share one preemption policy, extending existing checks for priority and priority class. PR 143702 adds end-to-end tests for Composite Pod Group since its promotion to beta, covering gang scheduling and unschedulable hierarchies. PR…
Finally, security and small correctness fixes. PR 143642 bumps the Go networking library for two CVEs. PR 143688 fixes the audit truncate backend to deep-copy events so truncation annotations don't leak into other backends. Also merged: a kubeadm version-policy error fix in PR 143629, and Container Stop Signals…
What's next: watch for feedback on the new cache feature gates, and for…
