##  External Dependencies

- Default etcd server is unchanged at v3.2.24 since Kubernetes 1.12. ([#68318](https://github.com/kubernetes/kubernetes/pull/68318))
- The list of validated docker versions remain unchanged at 1.11.1, 1.12.1, 1.13.1, 17.03, 17.06, 17.09, 18.06 since Kubernetes 1.12. ([#68495](https://github.com/kubernetes/kubernetes/pull/68495))

  
  This behavior will change to:
  - Services that have been set  IPFamilyPolicy = PreferDualstack will not be upgraded when the service object is updated. User can still change policy, type etc and existing behaviors remain the same.

- Introducing new semantic for metric `volume_operation_total_seconds` to be the end to end latency of volume provisioning/deletion. Existing metric "storage_operation_duration_seconds" will remain untouched, however it is exposed to the following potential issues:

- **[alpha]** Represent node problems "not ready" and "unreachable" using `NoExecute` taints. In combination with `tolerationSeconds` described below, this allows per-pod specification of how long to remain bound to a node that becomes unreachable or not ready, rather than using the default of 5 minutes. You can enable this alpha feature by including `TaintBasedEvictions=true` in `--feature-gates`, such as `--feature-gates=FooBar=true,TaintBasedEvictions=true`....

* Fixes an issue where Portworx volumes cannot be mounted if 9001 port is already in use on the host and users remap 9001 to another port. ([#70392](https://github.com/kubernetes/kubernetes/pull/70392), [@harsh-px](https://github.com/harsh-px))
