## New Features

  that was previously rejected by the VolemeZone plugin if  addition/update of node, 
  addition/update of PV, addition/update of PVC, or addition of SC matches pod's topology settings. ([#124996](https://github.com/kubernetes/kubernetes/pull/124996), [@Gekko0114](https://github.com/Gekko0114)) [SIG Scheduling and Storage]
- Kube-scheduler implements scheduling hints for the VolumeZone plugin.

* Provided API support for external CSI storage drivers to support block volumes. ([#64723](https://github.com/kubernetes/kubernetes/pull/64723), [@vladimirvivien](https://github.com/vladimirvivien))
* Volume topology aware dynamic provisioning for external provisioners is now supported. ([#63193](https://github.com/kubernetes/kubernetes/pull/63193), [@lichuqiang](https://github.com/lichuqiang))

In Kubernetes 1.19 this feature will be enabled by default with kube-proxy reading from EndpointSlices instead of Endpoints. Although this will mostly be an invisible change, it should result in noticeable scalability improvements in large clusters. It will also enable significant new features in future Kubernetes releases like Topology Aware Routing.

- Fixed Cronjob `status.lastSuccessfulTime` not populated by a manually triggered ([#118530](https://github.com/kubernetes/kubernetes/pull/118530), [@carlory](https://github.com/carlory))
- Fixed Topology Aware Hints not working when the `topology.kubernetes.io/zone` label is added after Node creation. ([#117245](https://github.com/kubernetes/kubernetes/pull/117245), [@tnqn](https://github.com/tnqn))

- **Scheduling**
  - [alpha] Allows pods to require or prohibit (or prefer or prefer not) co-scheduling on the same node (or zone or other topology domain) as another set of pods. ([docs](http://kubernetes.io/docs/user-guide/node-selection/) ([kubernetes/features#51](https://github.com/kubernetes/enhancements/issues/51))
- **Storage**

### AWS

- Kubernetes will now use the zone from the node for topology aware aws-ebs volume creation to reduce unnecessary cloud provider calls. ([#78276](https://github.com/kubernetes/kubernetes/pull/78276), [@zhan849](https://github.com/zhan849))
