* Add RequestedToCapacityRatioPriority priority function. Function is parametrized with set of points mapping node utilization (0-100) to score (0-10). ([#63929](https://github.com/kubernetes/kubernetes/pull/63929), [@losipiuk](https://github.com/losipiuk))
    * Function is linear between points. Resource utilization is defined as one minus ratio of total amount of resource requested by pods on node and node's capacity (scaled to 100).

  - The DynamicKubeletConfig feature gate is deprecated. The functionality is still accessible by using the kubeadm alpha kubelet enable-dynamic command.
  - The command `kubeadm config print-defaults` is deprecated in favor of `kubeadm config print init-defaults` and `kubeadm config print join-defaults` ([#69617](https://github.com/kubernetes/kubernetes/pull/69617), [@rosti](https://github.com/rosti))

### **Scheduling**

*   Taint key `unreachable` is now in GA.
*   Taint key `notReady` is changed to `not-ready`, and is also now in GA.
*   These changes are automatically updated for taints. Tolerations for these taints must be updated manually. Specifically, you must:
    *   Change `node.alpha.kubernetes.io/notReady` to `node.kubernetes.io/not-ready`

brings additional power to both local storage and Persistent Volumes. [Mount namespace propagation](https://github.com/kubernetes/enhancements/issues/432) allows a container to mount a volume as rslave so that host mounts can be seen inside the container, or as rshared so that mounts made inside a container can be seen by the host. (Note that this is [not supported on Windows](https://github.com/kubernetes/kubernetes/pull/60275).) [Local Ephemeral Storage Capacity Isolation](https://github.com/k...

The original `etcd_object_counts` metrics name is marked as "Deprecated" and will be removed in the future.
