- Introducing Memory quality of service support with `cgroups v2 (Alpha)`. The `MemoryQoS` feature is now in Alpha. This allows `kubelet` running with `cgroups v2` to set memory QoS at container, pod and QoS level to protect and guarantee better memory quality. This feature can be enabled through feature gate Memory QoS. ([#102970](https://github.com/kubernetes/kubernetes/pull/102970), [@borgerli](https://github.com/borgerli))

  Burstable QoS pods. For Best-Effort/Guaranteed QoS pods, swap would be disabled.
  
  Containers with memory requests equal to their memory limits also won't have
  swap access, and it is a way to opt-out of swap for a single container.
  
  The formula for the swap limit for Burstable QoS pods is:
  `(<memory-request>/<node-memory-capacity>)*<node-swap-capacity>`.

  flags+=" --resolv-conf=${WINDOWS_CNI_DIR}\hostdns.conf"

  # Both --cgroups-per-qos and --enforce-node-allocatable should be disabled on
  # windows; the latter requires the former to be enabled to work.
  flags+=" --cgroups-per-qos=false --enforce-node-allocatable="

  # Turn off kernel memory cgroup notification.
  flags+=" --kernel-memcg-notification=false"

- The topology manager aligns resources for pods of all QoS classes with respect to NUMA locality, not just Guaranteed QoS pods. ([#83492](https://github.com/kubernetes/kubernetes/pull/83492), [@ConnorDoyle](https://github.com/ConnorDoyle))
