- Added metrics to capture CPU distribution across NUMA nodes ([#130491](https://github.com/kubernetes/kubernetes/pull/130491), [@swatisehgal](https://github.com/swatisehgal)) [SIG Node and Testing]

- Added a `--topology-manager-policy-options` flag to the kubelet to support fine tuning the topology manager policies. The first policy option, `prefer-closest-numa-nodes`, allows these policies to favor sets of NUMA nodes with shorter distance between nodes when making admission decisions. ([#112914](https://github.com/kubernetes/kubernetes/pull/112914), [@PiotrProkop](https://github.com/PiotrProkop))

* Fixed a bug in the single-numa-policy of the TopologyManager. Previously, best-effort pods would result in a terminated state with a TopologyAffinity error. Now they will run as expected. ([#83777](https://github.com/kubernetes/kubernetes/pull/83777), [@lmdaly](https://github.com/lmdaly))...

- Fixed bug that caused cAdvisor to incorrectly detect single-socket multi-NUMA topology. ([#99315](https://github.com/kubernetes/kubernetes/pull/99315), [@iwankgb](https://github.com/iwankgb)) [SIG Node]

Align Up!

A beta feature of Kubernetes in release 1.18, the [Topology Manager feature](https://github.com/nolancon/website/blob/f4200307260ea3234540ef13ed80de325e1a7267/content/en/docs/tasks/administer-cluster/topology-manager.md) enables NUMA alignment of CPU and devices (such as SR-IOV VFs) that will allow your workload to run in an environment optimized for low-latency. Prior to the introduction of the Topology Manager, the CPU and Device Manager would make resource allocation decisions...
