### Deprecation

- Added support for vSphere in-tree volumes migration to vSphere CSI driver. The in-tree vSphere Volume plugin will be deprecated and removed in a future release.

## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

### Failing Test

- DRA driver helper: Fixed handling of apiserver restart when running on a Kubernetes version which did not support the `resource.k8s.io` version used by the DRA driver. ([#133076](https://github.com/kubernetes/kubernetes/pull/133076), [@pohly](https://github.com/pohly)) [SIG Node and Testing]

- Unlocked the `CSIMigrationvSphere` feature gate.
  The change allow users to continue using the in-tree vSphere driver,pending a vSphere
  CSI driver release that has with GA support for Windows, XFS, and raw block access. ([#116342](https://github.com/kubernetes/kubernetes/pull/116342), [@msau42](https://github.com/msau42)) [SIG Storage]

## Known Issues

- This release enables in-tree RBD migration to CSI driver with a couple of feature gates.  These featuregates are alpha in this release.

  - `CSIMigrationRBD`: when enabled, it will redirect traffic from in tree rbd plugin ( kubernetes.io/rbd )  to CSI driver ( rbd.csi.ceph.com) , default to `false` now.
  - `IntreePluginRBDUnregister`: Disables the RBD in-tree driver

  The feature gates can be enabled by:

- Promote CSIMigrationOpenStack to Beta (off by default since it requires installation of the OpenStack Cinder CSI Driver. The in-tree AWS OpenStack Cinder driver "kubernetes.io/cinder" was deprecated in 1.16 and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time. Users should...

- Prevented Pods from being scheduled onto nodes that lack the required CSI driver. ([#135012](https://github.com/kubernetes/kubernetes/pull/135012), [@gnufied](https://github.com/gnufied)) [SIG API Machinery, Scheduling, Storage and Testing]
