  - The deprecated `--etcd-quorum-read` flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove the `--etcd-quorum-read` flag from kube-apiserver invocations before upgrading.
- kube-controller-manager
  - The deprecated `--insecure-experimental-approve-all-kubelet-csrs-for-group` flag has been removed.

- Kubeadm: only enable the klog flags that are still supported for kubeadm, rather than hiding the unwanted flags. This means that the previously unrecommended hidden flags about klog (including `--alsologtostderr`, `--log-backtrace-at`, `--log-dir`, `--logtostderr`, `--log-file`, `--log-file-max-size`, `--one-output`, `--skip-log-headers`, `--stderrthreshold`...

- Enables YAML support for statusz and flagz. ([#135309](https://github.com/kubernetes/kubernetes/pull/135309), [@richabanker](https://github.com/richabanker)) [SIG API Machinery, Instrumentation and Testing]

## Action Required

- etcd2 as a backend is deprecated and support will be removed in Kubernetes 1.13.

* Make ThirdPartyResource a root scoped object ([#25006](https://github.com/kubernetes/kubernetes/pull/25006), [@liggitt](https://github.com/liggitt))
* mark container-port flag as deprecated ([#25072](https://github.com/kubernetes/kubernetes/pull/25072), [@AdoHe](https://github.com/AdoHe))
* Provide flags to use etcd3 backed storage ([#24455](https://github.com/kubernetes/kubernetes/pull/24455), [@hongchaodeng](https://github.com/hongchaodeng))

### Other notable changes

- The new flag `--chunk-size=SIZE` for `kubectl drain` has been promoted to beta, and enabled by default. This flag  may be used to alter the number of items or disable this feature when `0` is passed.
