FastAPI 0.126.0 dropped support for Pydantic v1, while still supporting `pydantic.v1` for a little while.

/// warning

The Pydantic team stopped support for Pydantic v1 for the latest versions of Python, starting with **Python 3.14**.

This includes `pydantic.v1`, which is no longer supported in Python 3.14 and above.

- Stopped expanding PVCs annotated with node-expand-not-required. ([#131907](https://github.com/kubernetes/kubernetes/pull/131907), [@gnufied](https://github.com/gnufied)) [SIG API Machinery, Etcd, Node, Storage and Testing]

- kube-apiserver: fixed a 1.31 regression that stopped honoring build ID overrides with the --version flag ([#126665](https://github.com/kubernetes/kubernetes/pull/126665), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

- Kubeadm: stopped applying the `--pod-infra-container-image` flag for the kubelet. The flag has been deprecated and no longer served a purpose in the kubelet as the logic was migrated to CRI (Container Runtime Interface). During upgrade, kubeadm will attempt to remove...

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

**Note**: have in mind that the Pydantic team already stopped supporting Pydantic v1 for recent versions of Python, starting with Python 3.14.
