### **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`

* 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).

* [alpha] Users can now add taints to nodes by condition ([design doc](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/taint-node-by-condition.md))

#### Storage

* [stable] Mount options

  the scheduler's in-tree plugins now subscribe to specific node events to decide whether to requeue Pods.
  This allows the scheduler to handle cluster events faster with less memory.
  
  Specific node events include updates to taints, tolerations or allocatable.
