- Added a health check for the device plugin gRPC registration server. When the registration server is down, kubelet is marked as unhealthy. If systemd watchdog is configured, this will result in a kubelet restart. ([#128432](https://github.com/kubernetes/kubernetes/pull/128432), [@zhifei92](https://github.com/zhifei92)) [SIG Node]

- kube-scheduler dropped support for configuration files with apiVersion `componentconfig/v1alpha1`. Ensure kube-scheduler is configured using command-line flags or a configuration file with apiVersion `kubescheduler.config.k8s.io/v1alpha1` before upgrading to 1.13.
- kubectl

- K8s.io/client-go: Fixes a regression in 1.34+ which prevented informers from using configured Transformer functions. ([#135580](https://github.com/kubernetes/kubernetes/pull/135580), [@serathius](https://github.com/serathius) [SIG API Machinery]
