### Taints and Tolerations
* Add a manager to NodeController that is responsible for removing Pods from Nodes tainted with NoExecute Taints. This feature is beta (as the rest of taints) and enabled by default. It's gated by controller-manager enable-taint-manager flag. ([#40355](https://github.com/kubernetes/kubernetes/pull/40355), [@gmarek](https://github.com/gmarek))

   * which the elements are provided to the method.
   *
   * @param anElement one of the elements the set should contain
   * @param otherElements the rest of the elements the set should contain
   * @return an immutable set containing those elements, minus duplicates

- Replaced deprecated package `k8s.io/utils/pointer` with `k8s.io/utils/ptr` for ./test/e2e and ./test/utils. ([#132763](https://github.com/kubernetes/kubernetes/pull/132763), [@PatrickLaabs](https://github.com/PatrickLaabs)) [SIG Autoscaling and Testing]

 - reach GA, and deprecate the beta, or
 - have a new beta version _(and deprecate the previous beta)_.

    *   Update CRI to kubernetes v1.9.
    *   Bug fixes in validation test suites.
*   [beta] [cri-containerd](https://github.com/kubernetes-incubator/cri-containerd): CRI implementation for containerd is now v1.0.0-beta.0, [[@Random-Liu](https://github.com/Random-Liu)]
    *   This release supports Kubernetes 1.9+ and containerd v1.0.0+.
    *   Pass all Kubernetes 1.9 e2e test, node e2e test and CRI validation tests.

* test/e2e/e2e.test: ([#69105](https://github.com/kubernetes/kubernetes/pull/69105), [@pohly](https://github.com/pohly))
   * -viper-config can be used to set also the options defined by command line flags
   * the default config file is "e2e.yaml/toml/json/..." and the test starts when no such config is found (as before) but if -viper-config is used, the config file must exist
