The `--feature-gates` flag now supports an `AllBeta=false` value which disables all beta feature gates. ([#84304](https://github.com/kubernetes/kubernetes/pull/84304), [@liggitt](https://github.com/liggitt))

- Removed feature gates `ServiceLoadBalancerClass` and `ServiceLBNodePortControl`. These feature gates were enabled (and locked) since `v1.24`. ([#112577](https://github.com/kubernetes/kubernetes/pull/112577), [@andrewsykim](https://github.com/andrewsykim))

- Promote StatefulSet minReadySeconds to GA. This means `--feature-gates=StatefulSetMinReadySeconds=true` are not needed on kube-apiserver and kube-controller-manager binaries and they'll be removed soon following policy at https://kubernetes.io/docs/reference/using-api/deprecation-policy/#deprecation ([#110896](https:...

- 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.
