The Resource Management Working Group graduated three features to beta in the 1.10 release.  First, [CPU Manager](https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/), which allows users to request exclusive CPU cores.  This helps performance in a variety of use-cases, including network latency sensitive applications, as well as applications that benefit from CPU cache residency.  Next, [Huge Pages](https://kubernetes.io/docs/tasks/manage-hugepages/scheduling-hugepages/), which...

    * Fixes volume detach from shutdown nodes.
* Enable insertId generation, and update Stackdriver Logging Agent image to 0.5-1.5.36-1-k8s. This help reduce log duplication and guarantee log order. ([#68920](https://github.com/kubernetes/kubernetes/pull/68920), [@qingling128](https://github.com/qingling128))

- The kube-controller-manager managed signers can now have distinct signing certificates and keys.  See the help about `--cluster-signing-[signer-name]-{cert,key}-file`.  `--cluster-signing-{cert,key}-file` is still the default. ([#90822](https://github.com/kubernetes/kubernetes/pull/90822), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Apps and...

### Removing deprecated flags in kubeadm

* Improves how 'kubectl' uses the terminal size when printing help and usage. ([#34502](https://github.com/kubernetes/kubernetes/pull/34502), [@fabianofranz](https://github.com/fabianofranz))

  - The `--export` flag for the `kubectl get` command, deprecated since v1.14, will be removed in v1.18.
  - `kubectl cp` no longer supports copying symbolic links from containers; to support this use case, see `kubectl exec --help` for examples using `tar` directly ([#82143](https://github.com/kubernetes/kubernetes/pull/82143), [@soltysh](https://github.com/soltysh))

- `--log-flush-frequency` had no effect in several commands or was missing. Help and warning texts were not always using the right format for a command (`add_dir_header` instead of `add-dir-header`). Fixing this included cleaning up flag handling in component-base/logs: that package no longer adds flags to the global flag sets....

- Kube-controller-manager's help will include controllers behind a feature gate in `--controllers` flag ([#120371](https://github.com/kubernetes/kubernetes/pull/120371), [@atiratree](https://github.com/atiratree)) [SIG API Machinery]

- Optimizing loadbalancer creation with the help of attribute Internal Traffic Policy: Local ([#114466](https://github.com/kubernetes/kubernetes/pull/114466), [@princepereira](https://github.com/princepereira)) [SIG Network]

* Added liveness probe to Heapster service. ([#31878](https://github.com/kubernetes/kubernetes/pull/31878), [@mksalawa](https://github.com/mksalawa))
* Adding clusters to the list of valid resources printed by kubectl help ([#31719](https://github.com/kubernetes/kubernetes/pull/31719), [@nikhiljindal](https://github.com/nikhiljindal))
