Kubernetes shipped NUMA device attributes for DRA workload placement [ref:17] while simultaneously hardening Windows node test infrastructure [ref:9] and cleaning up scheduler integration tests [ref:16].

In brief

Kubernetes DRA now has standard numaNode device attributes with SLIT-based helpers. NUMA awareness in device allocation just got less DIY.
Windows e2e node tests landed in Kubernetes presubmits. Windows support's been invisible in CI for years. This is overdue.
Kubernetes test-infra bumped Windows nodes to containerd 2.x. Old CRI implementations are finally getting phased out on the CI side.
KEP-6012: CompositePodGroup API shipped in Kubernetes. Pod group scheduling just became a core concern, not a plugin problem.
kube-api-linter's optionalorrequired check now enforces on flowcontrol APIs. Boring, necessary, shipped.

The DRA subsystem got its most significant upgrade in weeks with standard `numaNode` device attributes and SLIT-based helpers [1], enabling cross-driver NUMA co-placement without driver-specific workarounds. Windows testing got real teeth added with a new presubmit job that fires on Windows-related code changes [2], paired with a critical shift to containerd 2.x for all Windows test scenarios [3]. The core API layer is seeing active hardening: flowcontrol linters now enforce required and optional field tags across all API versions [5], addressing 108 existing violations in one pass. Meanwhile, test-infra overhauled how it validates job configuration, tightening org and repo label enforcement to prevent subtle sync bugs [4]. The scheduler got foundational work on the CompositePodGroup API implementation [6], clearing the way for workload affinity patterns that don't exist in 1.30. Across the board, dependency updates hit the release infrastructure [7] [8] [9], including the actions/setup-go migration to ESM.

Action items

→ Review and validate DRA device attributes in your custom device drivers against the new numaNode standard [ref:17] kubernetes/kubernetes [plan]
→ Update Windows test jobs to containerd 2.x to stay aligned with new validation gates [ref:10] kubernetes/test-infra [plan]
→ Audit your flowcontrol API field definitions for missing +required and +optional tags [ref:15] kubernetes/kubernetes [monitor]
