Implementation details.

- Fixes spurious 0 revisions listed when running `kubectl rollout history` for a StatefulSet ([#82643](https://github.com/kubernetes/kubernetes/pull/82643), [@ZP-AlwaysWin](https://github.com/ZP-AlwaysWin))

cluster-internal resources installed by kubeadm will be overwritten when upgrading from v1.6 to v1.7. ([#47081](https://github.com/kubernetes/kubernetes/pull/47081), [@luxas](https://github.com/luxas))

* kubeadm deb/rpm packages: cAdvisor doesn't listen on `0.0.0.0:4194` without authentication/authorization because of the possible information leakage. The cAdvisor API can still be accessed via `https://{node-ip}:10250/stats/`, though. ([kubernetes/release#356](https://github.com/kubernetes/release/pull/356),...

- Extend discovery GroupManager with Group lister interface ([#127524](https://github.com/kubernetes/kubernetes/pull/127524), [@mjudeikis](https://github.com/mjudeikis)) [SIG API Machinery]

- Added support to the kube-proxy nodePortAddresses / --nodeport-addresses option to
  accept the value "primary", meaning to only listen for NodePort connections
  on the node's primary IPv4 and/or IPv6 address (according to the Node object).
  This is strongly recommended, if you were not previously using
  --nodeport-addresses, to avoid surprising behavior.

- In kubelet, log verbosity and flush frequency can also be configured via the configuration file and not just via command line flags. In other commands (kube-apiserver, kube-controller-manager), the flags are listed in the "Logs flags" group and not under "Global" or "Misc". The type for `-vmodule` was made a bit more descriptive (`pattern=N,...` instead of `moduleSpec`). ([#106090](https://github.com/kubernetes/kubernetes/pull/106090), [@pohly](https://github.com/pohly))...

## Changelog since v1.10.5

### Action Required

- Kubeadm: Graduated the kubeadm-specific feature...

- Fixed panic when performing a `set env` operation on a `--local` resource ([#65636](https://github.com/kubernetes/kubernetes/pull/65636), [@juanvallejo](https://github.com/juanvallejo))
