Major improvements in this release:

  • The balloons policy becomes fully aware of hardware topology, able to utilize idle CPUs, and allows users to choose between packing or spreading workloads across CPUs.
  • CRI-RM becomes compatible with CRI v1 towards both kubelet and container runtimes. Backwards compatibility to CRI v1alpha2 is maintained in both directions, too.
  • Fixes a crash when pod status data is not available in the synchronization phase at cri-resmgr start-up.
