We were unable to find any usage of or basis for this and believe it may have been targeting a custom gitconfig shorthand syntax. ([#116598](https://github.com/kubernetes/kubernetes/pull/116598), [@natasha41575](https://github.com/natasha41575)) [SIG CLI]

networking.k8s.io/v1 API group. The structure remains unchanged from the v1beta1 API. The net.beta.kubernetes.io/network-policy annotation on Namespaces (used to opt in to isolation) has been removed. Instead, isolation is now determined on a per-pod basis. A NetworkPolicy may target a pod for isolation by including the pod in its spec.podSelector. Targeted Pods accept the traffic specified in the respective NetworkPolicy (and nothing else). Pods not targeted by any NetworkPolicy accept all traffic by...

- Added to `MutableFeatureGate` the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously.
