- 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]

- CEL cost estimator no longer treats enums as unbounded strings when determining its length. Instead, the length is set to the longest possible enum value. ([#121085](https://github.com/kubernetes/kubernetes/pull/121085), [@jiahuif](https://github.com/jiahuif)) [SIG API Machinery]

- Add --for=create option to kubectl wait ([#125868](https://github.com/kubernetes/kubernetes/pull/125868), [@soltysh](https://github.com/soltysh)) [SIG CLI and Testing]
- Add a TopologyManager policy option: max-allowable-numa-nodes to configures maxAllowableNUMANodes for kubelet. ([#124148](https://github.com/kubernetes/kubernetes/pull/124148), [@cyclinder](https://github.com/cyclinder)) [SIG Node and Testing]

- Fixed bug that caused cAdvisor to incorrectly detect single-socket multi-NUMA topology. ([#99209](https://github.com/kubernetes/kubernetes/pull/99209), [@iwankgb](https://github.com/iwankgb)) [SIG Node]

## Changelog since v1.20.11

## Changes by Kind

### API Change

- Kube-apiserver: Fixes handling of CRD schemas containing literal null values in enums (#104990, @liggitt) [SIG API Machinery, Apps and Network]

### Bug or Regression

- Detach volumes from vSphere nodes not tracked by attach-detach controller (#104910, @gnufied) [SIG Cloud Provider and Storage]

- Added a new `align-by-socket` policy option to cpu manager `static` policy.  When enabled CPU's to be aligned at socket boundary rather than NUMA boundary. ([#111278](https://github.com/kubernetes/kubernetes/pull/111278), [@arpitsardhana](https://github.com/arpitsardhana))

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...

* [fluentd-gcp addon] Fluentd now runs in its own network, not in the host one. ([#54395](https://github.com/kubernetes/kubernetes/pull/54395), [@crassirostris](https://github.com/crassirostris))
* fix azure storage account num exhausting issue ([#54459](https://github.com/kubernetes/kubernetes/pull/54459), [@andyzhangx](https://github.com/andyzhangx))
