+### Fixed
+- Fixed extended resources present on only a subset of nodes being reported as unavailable cluster-wide: `ResourceVector.SetMax` now grows the accumulator to the longer vector's length instead of silently dropping resource indices discovered after the first-iterated node, which caused pods requesting such resources to be rejected as unschedulable ("No node in the node-pool has X resources") depending on node map iteration order. [#1851](https://github.com/kai-scheduler/KAI-Scheduler/issues/1851)
+- Block NaN value for fraction in the pod admission [#1798](https://github.com/kai-scheduler/KAI-Scheduler/issues/1798) [davidLif](https://github.com/davidLif)
+- In the fractional admission checks, check that the fractional value can be parsed as a quantity. [#1798](https://github.com/kai-scheduler/KAI-Scheduler/issues/1798) [davidLif](https://github.com/davidLif)
+- Podgrouper now rejects negative PyTorch replica indexes and LWS worker indexes, and caps the number of subgroups created for block-level segmentation at 10000 to avoid unbounded PodGroup fan-out. [davidLif](https://github.com/davidLif)
+- Fixed GPU-sharing pods with dotted pod names generating invalid ConfigMap-backed volume names. Volume names are now sanitized to valid DNS labels while preserving original ConfigMap references used for shared-GPU injection.
+- Fixed scheduler panic during reclaim when building eviction messages for jobs in root-level queues (`ParentQueue` empty) that reclaim across hierarchy branches. [#1863](https://github.com/kai-scheduler/KAI-Scheduler/issues/1863)
+- Fixed GPU-sharing pods with dotted pod names generating invalid ConfigMap-backed volume names. Volume names are now sanitized to valid DNS labels while preserving original ConfigMap references used for shared-GPU injection. [#1728](https://github.com/kai-scheduler/KAI-Scheduler/issues/1728)
+- Allow creating PodGroups with an explicit minMember of 0
