Changelog since v1.36.3

Changes by Kind

Feature

Added support for per-container targeting of cpu-load-balancing.crio.io, irq-load-balancing.crio.io, and cpu-quota.crio.io annotations. A container name can be appended to the annotation key (e.g. cpu-load-balancing.crio.io/my-container: “disable”) to apply the setting to a specific container rather than all containers in the pod. Container-specific annotations take precedence over pod-level annotations when both are present. (#10152, @openshift-cherrypick-robot)

Bug or Regression

Fix CRI-O crash (nil pointer dereference) in ListPodSandboxStats when a container’s cgroup is cleaned up during teardown. (#10216, @openshift-cherrypick-robot)
Fix a bug in high performance hooks where an init container would continue to hold a cpuset that could be used by a regular container in the same pod. (#10236, @openshift-cherrypick-robot)
