v0.9.0

What's New since v0.8.4

New dynamic-pools policy

A new policy that allows applications to be assigned to dynamically resized CPU pools. The pools are non-overlapping and are resized based on the resource requests of the containers and the actual CPU utilization of the application.

Enhancements to balloons policy

New PreferSpreadOnPhysicalCores configuration option in the balloons policy. Enabling this option for a balloon makes the CPU allocator to prefer CPUs from separate physical CPU cores.

There are also bugfixes to dynamic configuration updates.

CRI v1alpha2 dropped

Support for deprecated CRI version v1alpha2 was removed. This means that CRI-RM v0.9 requires Kubernetes v1.23 (or later) and containerd v1.6 (or later) or CRI-O v1.20 (or later).
