### 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.

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...

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint. ([#118510](https://github.com/kubernetes/kubernetes/pull/118510), [@SataQiu](https://github.com/SataQiu)) [SIG Testing]

 - Default `StreamingProxyRedirects` to disabled. If there is a >= 2 version skew between master and nodes, and the old nodes were enabling `--redirect-container-streaming`, this will break them. In this case, the `StreamingProxyRedirects` can still be manually enabled. ([#101647](https://github.com/kubernetes/kubernetes/pull/101647), [@paco...

- Pod status updates faster when reacting on probe results. The first readiness probe will be called faster when startup probes succeeded, which will make Pod status as ready faster. ([#98376](https://github.com/kubernetes/kubernetes/pull/98376), [@matthyx](https://github.com/matthyx))

- 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.
