## Dependencies

### Added

The Cluster API effort is currently undergoing a complete rehaul of the existing codebase, moving off Terraform and into using govmomi directly.

### SIG-windows

One of the **biggest benefits** is that now you can create `Annotated` dependencies that are then shared by multiple *path operation functions*, this will allow you to **reduce** a lot of **code duplication** in your codebase, while keeping all the support from editors and tools.

For example, you could have code like this:

```Python
def get_current_user(token: str):
    # authenticate user
    return User()

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, extending the alpha volume-resizing support to more volume plugins, and...

### Deprecation of PodSecurityPolicy

* Add ready replicas in Deployments ([#37959](https://github.com/kubernetes/kubernetes/pull/37959), [@kargakis](https://github.com/kargakis))
* Remove all MAINTAINER statements in Dockerfiles in the codebase as they are deprecated by docker ([#38927](https://github.com/kubernetes/kubernetes/pull/38927), [@luxas](https://github.com/luxas))
