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).

- 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))

- Kubelet: the deprecated `--master-service-namespace` flag is removed in v1.27 ([#116015](https://github.com/kubernetes/kubernetes/pull/116015), [@SataQiu](https://github.com/SataQiu))

- 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.

### Bug or Regression

- Fixed a bug where a high churn of events was causing master instability by reducing the maximum number of objects (events) attached to a single etcd lease. ([#100452](https://github.com/kubernetes/kubernetes/pull/100452), [@mborsz](https://github.com/mborsz)) [SIG API Machinery and Instrumentation]

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...

### Promoted Local Ephemeral Storage Capacity Isolation to Stable

 - 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...
