[ANNOUNCE] kueue 0.17.0 is released

[Michał Woźniak]

We have just released Kueue v0.17.0.

For more details, please check the release notes and the documentation.

Highlights:

1. Performance and Scalability: Scheduler throughput is significantly improved for large clusters. Key enhancements include faster TAS snapshotting, alpha support for bulk scheduling with equivalence hashes (SchedulingEquivalenceHashing), smarter throttling of inadmissible requeues, and reduced memory usage through stripping managedFields. See blogpost.
2. Topology-Aware Scheduling: Node hot swap now supports node taints, and TAS snapshotting performance has improved further. The release also introduces multi-layered scheduling for next-generation accelerator hardware, along with ResourceTransformations support for virtual credit–style resources to enable quota sharing across multiple flavors.
3. MultiKueue: now supports LeaderWorkerSet and RayService.. It also introduces alpha support for orchestrated preemption, ensuring that only one worker cluster performs preemption at a time.
4. Expanded AI/ML Integrations: Kueue continues to strengthen its ML ecosystem support with native KubeRay RayService management, support for Kubeflow Trainer v2.2, and a new SparkApplication integration available behind a feature gate.
5. KueueViz and Observability: KueueViz adds token-based authentication, resource reporting, and a hierarchical tree view. Observability is also enhanced with new cohort metrics, custom Prometheus labels, and the graduation of LocalQueue metrics to beta, enabled by default.
6. Scheduling and Fairness: Fair Sharing now favors workloads within nominal quota more predictably. New controls include admission gating with the kueue.k8s.io/admission-gated-by annotation, and priority boosting via the workload annotation kueue.x-k8s.io/priority-boost. DRA integration also adds alpha support for extended resources.
7. Core Features Graduated to GA: Several key queueing and cohort-management capabilities are now generally available, including LendingLimit, LocalQueueDefaulting, ObjectRetentionPolicies, SanitizePodSets, and HierarchicalCohorts

Thank you to the contributors who reported issues, implemented features, fixed bugs, etc.

Cheers,
Michal
