### kubeadm
* A new label and taint is used for marking the master. The label is `node-role.kubernetes.io/master=""` and the taint has the effect `NoSchedule`. Tolerate the `node-role.kubernetes.io/master="":NoSchedule` taint to schedule a workload on the master (a networking DaemonSet for example).
* The kubelet API is now secured, only cluster admins are allowed to access it.

- kubeadm: all master components are now exclusively relying on the `PriorityClassName` pod spec for annotating them as cluster critical components. Since `scheduler.alpha.kubernetes.io/critical-pod` annotation is no longer supported by Kubernetes 1.14 this annotation is no longer added to master components.

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).

### SIG Azure

* The Azure cloud provider now supports standard SKU load balancer and public IP.
`excludeMasterFromStandardLB` defaults to true, which means master nodes are excluded from the standard load balancer. Also note that because all nodes (except master) are added as loadbalancer backends, the standard load balancer doesn't work with the `service.beta.kubernetes.io/azure-load-balancer-mode` annotation.

a critical security issue in the Kubernetes API Server, is resolved in v1.13.0 (and in [v1.10.11](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.10.md/#v11011), [v1.11.5](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.11.md/#v1115), and [v1.12.3](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.12.md/#v1123)). We recommend all clusters running previous versions update to one of these releases immediately. See issue...
