Koordinator v1.8: Introducing Koord-Queue, Reservation Pre-Allocation, and Expanded Heterogeneous Device Support

Background ​ AI and batch workloads continue to drive the evolution of Kubernetes scheduling. As clusters grow larger and workloads become more diverse, users demand richer queueing semantics, more accurate resource reservation, deeper observability, and unified management across increasingly heterogeneous hardware. Since its open-source release in April 2022, Koordinator has delivered 16 major versions, providing an end-to-end solution for workload orchestration, co-location, fine-grained scheduling, isolation, and performance optimization.
