 ### Fixed
+- Fixed scheduler pod cache memory growth by transforming cached Pods to retain only scheduler-relevant container fields while stripping large literal env values and managed fields [#1646](https://github.com/kai-scheduler/KAI-Scheduler/issues/1646)
 - Fix the MinNodeGPUMemoryMiB calculation in the scheduler. This affected allocations for fractional pod requesting gpu "gpu-memory". [#1795](https://github.com/kai-scheduler/KAI-Scheduler/issues/1795) [davidLif](https://github.com/davidLif)
 - Use the maximum gpu size ine the cluster rather then the minimum when checking a potential overLimit or isNonPreemptebleOverquota for a pod. [#1792](https://github.com/kai-scheduler/KAI-Scheduler/issues/1795) [davidLif](https://github.com/davidLif)

 - Reduced scheduler heap retention after scheduling cycles by clearing completed session snapshots and callback references, and by releasing the node scoring pool without waiting for finalizers.
 - Fixed Helm chart prometheus RBAC always being installed when `prometheus.enabled` is false, and the `kai-prometheus` ClusterRoleBinding referencing the `prometheus` ServiceAccount in hardcoded `kai-scheduler` namespace instead of the Helm release namespace [#1684](https://github.com/kai-scheduler/KAI-Scheduler/pull/1684) [dttung2905](https://github.com/dttung2905)
 - Fixed post-delete cleanup hook hardcoding `kai-scheduler` namespace instead of Helm release namespace on `helm uninstall` [#1619](https://github.com/kai-scheduler/KAI-Scheduler/pull/1619) [dttung2905](https://github.com/dttung2905)
-- Fixed scheduler pod cache memory growth by transforming cached Pods to retain only scheduler-relevant container fields while stripping large literal env values and managed fields [#1646](https://github.com/kai-scheduler/KAI-Scheduler/issues/1646)
 - Improved solver performance in some large reclaim scenarios [#1627](https://github.com/kai-scheduler/KAI-Scheduler/pull/1627) [itsomri](https://github.com/itsomri)
 - Grove grouper now sets `minSubGroup` (equal to the number of child SubGroups) instead of `minMember=0` on parent SubGroups generated from `topologyConstraintGroupConfigs` [#1639](https://github.com/kai-scheduler/KAI-Scheduler/issues/1639) [davidLif](https://github.com/davidLif)
 - Fixed Helm chart not wiring `podgrouper.queueLabelKey` into `spec.global.queueLabelKey` on the Config CR, so custom queue label keys were ignored at install time [#1655](https://github.com/kai-scheduler/KAI-Scheduler/pull/1655) [dttung2905](https://github.com/dttung2905)
