Storage made Kubernetes more pluggable and modular by introducing an alpha implementation of the Container Storage Interface (CSI). CSI will make installing new volume plugins as easy as deploying a pod, and enable third-party storage providers to develop their plugins without the need to add code to the core Kubernetes codebase.

The SIG also focused on adding functionality to the Kubernetes volume subsystem, such as alpha support for exposing volumes as block devices inside containers,...

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.

There is no intermediate action required by end-users, because `v1` and `v1alpha2` do not differ in their implementation.
It is likely that `v1alpha2` will be removed in one of the future Kubernetes releases to be able to develop `v1`.
