- Removed `WindowsHostProcessContainers` feature-gate. ([#117570](https://github.com/kubernetes/kubernetes/pull/117570), [@marosset](https://github.com/marosset)) [SIG API Machinery, Apps, Auth, Node and Windows]
- Revised the comment about the feature-gate level for `PodFailurePolicy` from alpha to beta. ([#117802](https://github.com/kubernetes/kubernetes/pull/117802), [@kerthcet](https://github.com/kerthcet)) [SIG API Machinery and Apps]

We expect this implementation to progress from alpha to beta and GA in coming releases, so we’re eager to have you comment about your dual-stack experiences in [#k8s-dual-stack](https://kubernetes.slack.com/messages/k8s-dual-stack) or in [enhancements #563](https://features.k8s.io/563).
