### CSI Service Account Token

    * A sample DaemonSet to deploy Flexvolume drivers is now available.

* [prototype] Volume snapshots

  * You can now create a volume snapshot by calling the Kubernetes API.

  * Note that the prototype does not support quiescing before snapshot, so snapshots might be inconsistent.

With Kubernetes v1.12, SIG Storage also introduced alpha support for [volume snapshotting](https://github.com/kubernetes/enhancements/issues/177). This feature introduces the ability to create/delete volume snapshots and create new volumes from a snapshot using the Kubernetes API.

### SIG-vmware

### Beta
- The Kubernetes Volume Snapshot feature has been moved to beta. The VolumeSnapshotDataSource feature gate is on by default in this release. This feature enables you to take a snapshot of a volume (if supported by the CSI driver), and use the snapshot to provision a new volume, pre-populated with data from the snapshot.

- Fix scheduler cache snapshot when a Node is deleted before its Pods ([#95154](https://github.com/kubernetes/kubernetes/pull/95154), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

 - All StorageClass parameters for volume provisioning are supported.
 - All features supported with PersistentVolumeClaims are supported, such as storage capacity tracking, snapshots and restore, and volume resizing.

### Immutable Secrets and ConfigMaps (beta)

Additionally, these Kubernetes snapshot primitives act as basic building blocks that unlock the ability to develop advanced, enterprise-grade, storage administration features for Kubernetes: including application or cluster level backup solutions.
Note that snapshot support will require Kubernetes distributors to bundle the Snapshot controller, Snapshot CRDs, and validation webhook. In addition, a CSI driver supporting the snapshot functionality must also be deployed on the cluster.

- kubeadm will now not fail preflight checks when running on >= 5.0 Linux kernel ([#74355](https://github.com/kubernetes/kubernetes/pull/74355), [@brb](https://github.com/brb))
- Scheduler cache snapshot algorithm has been optimized to improve scheduling throughput. ([#74041](https://github.com/kubernetes/kubernetes/pull/74041), [@bsalamat](https://github.com/bsalamat))
