With CSI the Kubernetes volume layer becomes truly extensible, allowing third party storage developers to write drivers making their storage systems available in Kubernetes without having to touch the core code.

CSI was first introduction as alpha in Kubernetes v1.9 and moved to beta in Kubernetes v1.10.

* Fix for Pod stuck in ContainerCreating with error "Volume is not yet attached according to node". ([#50806](https://github.com/kubernetes/kubernetes/pull/50806), [@verult](https://github.com/verult))
* Fixed controller manager crash by making it tolerant to discovery errors.([#49767](https://github.com/kubernetes/kubernetes/pull/49767), [@deads2k](https://github.com/deads2k))

- Renames the timeout field for the DelegatingAuthenticationOptions to TokenRequestTimeout and set the timeout only for the token review client. Previously the timeout was also applied to watches making them reconnecting every 10 seconds.

- Fixes a regression exposed in 1.27 by kubectl switching to openapi v3 by making apiregistration.k8s.io discoverable in openapi/v3 ([#119841](https://github.com/kubernetes/kubernetes/pull/119841), [@atiratree](https://github.com/atiratree)) [SIG API Machinery]

@app.post("/items/", response_model=ItemV2)
def create_item(item: Item):
    return {"title": item.name, "summary": item.description}
```

Adding this feature was a big effort with the main objective of making it easier for the few applications still stuck in Pydantic v1 to migrate to Pydantic v2.

And with this, support for **Pydantic v1 is now deprecated** and will be **removed** from FastAPI in a future version soon.

* Filter published OpenAPI schema by making nullable, required fields non-required in order to avoid kubectl to wrongly reject null values. ([#85733](https://github.com/kubernetes/kubernetes/pull/85733), [@sttts](https://github.com/sttts))
