Good morning, it's Friday, November 13th, 2026.
The lead story is Dynamic Resource Allocation. Multiple fixes ensure administrative access to devices isn't blocked by normal capacity limits.
First theme, D R A correctness and sharing. Two linked fixes, PR 144073 and PR 144119, make admin requests skip capacity accounting, minimum rounding, and shared counter reservations across all three allocator implementations. In practice, an admin probe won't be rejected just because a G P U or other consumable…
Second, API server scale and startup. PR 143874 caches Open API version 3 resources in client-go and kubectl, with benchmarks showing faster apply. PR 144033 cuts bootstrap gets by using lists to skip up-to-date namespaced R B A C objects. For observability, PR 141451 adds alpha metrics for stalled watchers served…
Third, node and control-plane hardening. PR 142515 brings kubelet support for pulling and garbage-collecting O C I seccomp profiles before sandbox and container creation. PR 144091 preserves the no-swap mount option when resizing memory-backed empty dir volumes, fixing remount failures on older kernels. On the CLI…
What's next: cluster operators should test D R A admin access…
