- Kubernetes v1.13 moves support for Container Storage Interface to GA. As part of this move Kubernetes now supports CSI v1.0.0 and deprecates support for CSI 0.3 and older releases. Older CSI drivers must be updated to CSI 1.0 and moved to the new kubelet plugin registration directory in order to work with Kubernetes 1.15+. ([#71020](https://github.com/kubernetes/kubernetes/pull/71020),...

DaemonSet, Deployment, ReplicaSet and StatefulSet kinds. This group and version are part
of the Kubernetes Workloads API. We plan to move them to v1 in an upcoming release, so you might want to plan your migration accordingly.

For more information, see [the issue that describes this work in detail](https://github.com/kubernetes/enhancements/issues/353)

#### API Object Additions and Migrations

* add goroutine to move unschedulable pods to activeq if they are not retried for more than 1 minute ([#72558](https://github.com/kubernetes/kubernetes/pull/72558), [@denkensk](https://github.com/denkensk))

*   deviceplugin has been extended to more gracefully handle the full device plugin lifecycle, including: ([#55088](https://github.com/kubernetes/kubernetes/pull/55088),[ @jiayingz](https://github.com/jiayingz))
    *   Kubelet now uses an explicit cm.GetDevicePluginResourceCapacity() function that makes it possible to more accurately determine what resources are inactive and return a more accurate view of available resources.

#### Generic API Server
* Move pkg/api/rest into genericapiserver ([#39948](https://github.com/kubernetes/kubernetes/pull/39948), [@sttts](https://github.com/sttts))
* Move non-generic apiserver code out of the generic packages ([#38191](https://github.com/kubernetes/kubernetes/pull/38191), [@sttts](https://github.com/sttts))

* Print `SizeLimit` of `EmptyDir` in `kubectl describe pod` outputs. ([#69279](https://github.com/kubernetes/kubernetes/pull/69279), [@dtaniwaki](https://github.com/dtaniwaki))
* add goroutine to move unschedulable pods to activeq if they are not retried for more than 1 minute ([#72558](https://github.com/kubernetes/kubernetes/pull/72558), [@denkensk](https://github.com/denkensk))

See [this doc](https://github.com/kubernetes/community/blob/master/sig-storage/volume-plugin-faq.md#kubernetes-volume-plugin-faq-for-storage-vendors) for more information.
Maintainers of FlexVolume drivers should implement a CSI driver and move users of FlexVolume to CSI.
Users of FlexVolume should move their workloads to CSI driver.
