- Supported fine-grained supplemental groups policy (KEP-3619), which enabled
  fine-grained control for supplementary groups in the first container processes.
  This allows you to choose whether to include groups defined in the container image (/etc/groups)

* [fluentd-gcp addon] Bump fluentd-gcp-scaler to v0.5.2 to pick up security fixes. ([#76762](https://github.com/kubernetes/kubernetes/pull/76762), [@serathius](https://github.com/serathius))
* specify azure file share name in azure file plugin ([#76988](https://github.com/kubernetes/kubernetes/pull/76988), [@andyzhangx](https://github.com/andyzhangx))

* kubeadm will now pull required images during preflight checks if it cannot find them on the system. ([#64105](https://github.com/kubernetes/kubernetes/pull/64105), [@chuckha](https://github.com/chuckha))

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.
  * The webhook and log file now output the `v1beta1` event format.

- Added a new command line argument `--interactive` to kubectl. The new command line argument lets a user confirm deletion requests per resource interactively. ([#114530](https://github.com/kubernetes/kubernetes/pull/114530), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]

  - `--service-account-key-file`, set to one or more files containing one or more public keys used to verify tokens.

- 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/kubern...

 - [Action Required] CSI drivers that call IsLikelyNotMountPoint should not assume false means that the path is a mount point. Each CSI driver needs to make sure correct usage of return value of IsLikelyNotMountPoint because if the file is an irregular file but not a mount point is acceptable ([#129370](https://github.com/kubernetes/kubernetes/pull/129370), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage and Windows]

* Removing `--prom-push-gateway` flag from e2e tests ([#52485](https://github.com/kubernetes/kubernetes/pull/52485), [@nielsole](https://github.com/nielsole))
* If a container does not create a file at the `terminationMessagePath`, no message should be output about being unable to find the file. ([#52567](https://github.com/kubernetes/kubernetes/pull/52567), [@smarterclayton](https://github.com/smarterclayton))
