enabled, you can create Services which can use IPv4, IPv6, or both, and you can change this setting for existing Services. Details are available in updated [IPv4/IPv6 dual-stack docs](https://docs.k8s.io/concepts/services-networking/dual-stack/), which cover the nuanced array of options.

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.c...

forwarded to kubelet static pods to control pull policy for etcd and control plane images. This option allows for precise image pull policy specification for master nodes and thus for more tight control over images. It is useful in CI environments and in environments, where the user has total control over master VM templates (thus, the master VM templates can be preloaded with the required Docker images for the control plane services).

- A new `kubelet_preemptions` metric is reported from Kubelets to track the number of preemptions occurring over time, and which resource is triggering those preemptions. ([#84120](https://github.com/kubernetes/kubernetes/pull/84120), [@smarterclayton](https://github.com/smarterclayton))

- RemoteCommand feature gates for kubectl exec, cp, and attach over WebSockets are now enabled by default (Beta):

- Fixed a bug that a pod's .status.nominatedNodeName is not cleared properly, and thus over-occupied system resources. ([#107109](https://github.com/kubernetes/kubernetes/pull/107109), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]
