  - [beta] Kubelet integrates with memcg notification API to detect when a hard eviction threshold is crossed ([kubernetes/features#125](https://github.com/kubernetes/enhancements/issues/125))

### Bug or Regression

- Add `--detach-keys` flag to `kubectl attach` and `kubectl run`, allowing detach without terminating the container ([#134997](https://github.com/kubernetes/kubernetes/pull/134997), [@yangjunmyfm192085](https://github.com/yangjunmyfm192085)) [SIG API Machinery and CLI]

- Adds support for `InterfaceNamePrefix` and `BridgeInterface` as arguments to `--detect-local-mode` option and also introduces a new optional `--pod-interface-name-prefix` and `--pod-bridge-interface` flags to kube-proxy. ([#95400](https://github.com/kubernetes/kubernetes/pull/95400), [@tssurya](https://github.com/tssurya))
