Highlighted below are the changes made since the previous release (v0.24.9):

⚠️ BREAKING CHANGES

• The API Group of CRD PodGroup and ElasticQuota is migrated to scheduling.x-k8s.io. The brand new installations don't need to do anything. Users migrating to this release need to do the following steps:
  • use kubectl replace -f <crds> to ensure new CRDs function well
  • migrate the labels - new label is using a style of *.scheduling.x-k8s.io/<label-name>, e.g., scheduling.x-k8s.io/pod-group
• Helm chart now leverages --namespace scheduler-plugins --create-namespace to consolidate both Helm release meta info and chart artifacts in the same namespace. Moreover, it enables users to customize the installation namespace.

⭐ Major changes:

• new ScoringStrategy LeastNUMANodes for NodeResourceTopologyMatch plugin that will score nodes based on how many NUMA nodes are required to satisfy resource requirements of given pod
• refactoring in NodeResourceTopologyMatch plugin
• support scheduler component config v1
• PodGroup and ElasticQuota now serve /status as a standard subresrouce
• (WIP) migrate to controller-runtime to replace typed clientset
• bumped the Kubernetes dependency to v1.25.7
