- Images for cloud-controller-manager, kube-apiserver, kube-controller-manager, and kube-scheduler now contain a minimal /etc/nsswitch.conf and should respect /etc/hosts for lookups ([#69238](https://github.com/kubernetes/kubernetes/pull/69238), [@BenTheElder](https://github.com/BenTheElder))

### 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.

- Kubemark: added two flags, `--kube-api-qps` which indicates the maximum QPS to the apiserver, and `--kube-api-burst` which indicates maximum burst for throttle to the apiserver. ([#124147](https://github.com/kubernetes/kubernetes/pull/124147), [@devincd](https://github.com/devincd))

The [dynamic maximum volume count](https://github.com/kubernetes/enhancements/issues/554) feature was also moved to beta. This enables a volume plugin to specify the maximum number of a given volume type per node as a function of the node characteristics (for example, a larger limit for larger nodes, a smaller limit for smaller nodes).

- Kubelet allows pods to use the `net.ipv4.ip_local_reserved_ports` sysctl by default and the minimal kernel version is 3.16; Pod Security admission allows this sysctl in v1.27+ versions of the baseline and restricted policies.

- The kube-proxy image contains `/go-runner` as a replacement for deprecated klog flags. ([#106301](https://github.com/kubernetes/kubernetes/pull/106301), [@pohly](https://github.com/pohly))
- The maximum length of the `CSINode` id field has increased to 256 bytes to match the CSI spec. ([#104160](https://github.com/kubernetes/kubernetes/pull/104160), [@pacoxu](https://github.com/pacoxu))

I wouldn't be in Bill's place for a good deal:  this fireplace is
narrow, to be sure; but I THINK I can kick a little!'

  She drew her foot as far down the chimney as she could, and
waited till she heard a little animal (she couldn't guess of what
sort it was) scratching and scrambling about in the chimney close
above her:  then, saying to herself `This is Bill,' she gave one
sharp kick, and waited to see what would happen next.
