Kubernetes: Backport Season and the Great Feature Gate Cleanup
A heavy wave of cherry picks landed fixes for DRA allocation, scheduler namespace selectors, and startup probes across four release branches, while a parallel cleanup effort stripped out graduated feature gates and reorganized watch cache internals.

This is Kubernetes, your development briefing for September 12th, 2026.
The dominant pattern today is backporting. A single fix rarely shipped once — it shipped four times, once per supported release branch.
Start with dynamic resource allocation. The integer overflow fix in per-claim device limit checks, originally PR 141307, got cherry-picked into releases 1.34 through 1.37 by thc1006 in PRs 141922 through 141925. Around it, divyanshuprakas-h's PR 141898 fixed how the allocator handles invalid all-device allocation,…
The same backport pattern shows up in scheduling and kubelet. The job controller's finalizer-removal fix from PR 141329 went out to three branches. A scheduler regression around negative namespace selector evaluation, PR 141563, is being backported to 1.34 and 1.35. And a startup probe gating fix, PR 141342, where…
Second theme: deprecation cleanup. Danwinship's PR 141762 removed the MultiCIDRServiceAllocator and DisableAllocatorDualWrite feature gates, both long GA. Antcybersec's PR 142051 is doing the same for three service account token gates from KEP-4193. This is routine maintenance, but it shrinks the configuration…
Third, infrastructure quality: rpb-ant's PR…
