### **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`

* The calico-node addon tolerates all NoExecute and NoSchedule taints by default. So Calico components can even be scheduled on tainted nodes. ([#57122](https://github.com/kubernetes/kubernetes/pull/57122), [@caseydavenport](https://github.com/caseydavenport))

- The following feature gates for volume expansion GA features have now been removed and must no longer be referenced in `--feature-gates` flags: `ExpandCSIVolumes`, `ExpandInUsePersistentVolumes`, `ExpandPersistentVolumes` ([#113942](https://github.com/kubernetes/kubernetes/pull/113942), [@mengjiao-liu](https://github.com/mengjiao-liu))...

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint. ([#118510](https://github.com/kubernetes/kubernetes/pull/118510), [@SataQiu](https://github.com/SataQiu)) [SIG Testing]...

* [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

* A new `TaintNodesByCondition` admission plugin taints newly created Node objects as "not ready", to fix a race condition that could cause pods to be scheduled on new nodes before their taints were updated to accurately reflect their reported conditions. This admission plugin is enabled by default if the `TaintNodesByCondition` feature is enabled. ([#73097](https://gi...

* /test/e2e/framework: Adds a flag "non-blocking-taints" which allows tests to run in environments with tainted nodes. String value should be a comma-separated list. ([#81043](https://github.com/kubernetes/kubernetes/pull/81043), [@johnSchnake](https://github.com/johnSchnake))...

- Fixes v1.17.0 regression in --service-cluster-ip-range handling with IPv4 ranges larger than 65536 IP addresses ([#86534](https://github.com/kubernetes/kubernetes/pull/86534), [@liggitt](https://github.com/liggitt)) [SIG Network]
