December 2025 monthly summary for kubernetes-sigs/kueue: Delivered a critical bug fix to the Topology-Aware Scheduling Activation Guard. Preemption now respects the TopologyAwareScheduling feature gate, ensuring topology-aware scheduling requests are processed only when the feature is enabled. This reduces risk of unintended behavior in environments where the feature flag is off and aligns behavior with configuration semantics.
