Three critical production fixes ship across core scheduler, metrics, and admission layers while DRA resource tracking stabilizes after surfacing a crash bug in the informer.

In brief

DRA graduates to stable in Kubernetes. Resource slice tracker informer lands. Device plugins no longer in beta. That's the GA you've been waiting for.
kubelet can now skip cadvisor's container discovery when using CRI stats. One less layer to parse. Metrics pipelines just got simpler.
Namespace lifecycle admission finally allows updates to resources in deleted namespaces. The blocker's gone. Terminating clusters aren't stuck anymore.
node-problem-detector now caches compiled regexes in the log buffer. Fewer allocations per match. Better CPU efficiency for long-running detectors.

Dynamic Resource Allocation locked its PrioritizedList feature to stable default-on after proving itself in 1.36 [4], but not before engineers uncovered a crash in the resource slice tracker when OnDelete events fire without the deleted DeviceTaintRule [1]. The fix migrates to type-safe informer APIs that caught the bug immediately. In parallel, kubelet now bypasses cAdvisor container discovery entirely when using CRI stats [2], eliminating redundant metric collection and simplifying the observability stack. The NamespaceLifecycle admission plugin got a critical fix [3] that now allows Updates to orphaned objects still sitting in etcd after their namespace deletes, unblocking storage version migration for stranded resources. Cloud provider vsphere bumped to Kubernetes v0.37.0-beta.0 after a false start [5] [6] [7] [8], and node-problem-detector shipped a 12x performance win by caching compiled regexes in the log buffer [9], cutting per-call latency from 2590ns to 211ns.

Action items

→ Upgrade cluster-autoscaler to 9.59.0 for DRA documentation support kubernetes/autoscaler [plan]
→ Monitor kubelet CRI stats adoption for metrics accuracy kubernetes/kubernetes [monitor]
