Breaking Changes

* 🔒️ Add `strict_content_type` checking for JSON requests. PR [14978](https://github.com/fastapi/fastapi/pull/14978) by [tiangolo](https://github.com/tiangolo).
 * Now FastAPI checks, by default, that JSON requests have a `Content-Type` header with a valid JSON value, like `application/json`, and rejects requests that don't.
 * If the clients for your app don't send a valid `Content-Type` header you can disable this with `strict_content_type=False`.
 * Check the new docs: [Strict Content-Type Checking](https://fastapi.tiangolo.com/advanced/strict-content-type/).

0.120.0

There are no major nor breaking changes in this release. ☕️

The internal reference documentation now uses `annotated_doc.Doc` instead of `typing_extensions.Doc`, this adds a new (very small) dependency on [`annotated-doc`](https://github.com/fastapi/annotated-doc), a package made just to provide that `Doc` documentation utility class.

I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc).

This new version `0.120.0` only contains that transition to the new home package for that utility class `Doc`.

0.119.0

FastAPI now (temporarily) supports both Pydantic v2 models and `pydantic.v1` models at the same time in the same app, to make it easier for any FastAPI apps still using Pydantic v1 to gradually but quickly **migrate to Pydantic v2**.

Python
from fastapi import FastAPI
from pydantic import BaseModel as BaseModelV2
from pydantic.v1 import BaseModel


class Item(BaseModel):
 name: str
 description: str | None = None


class ItemV2(BaseModelV2):
 title: str
 summary: str | None = None


app = FastAPI()


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.

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

You can read in the docs more about how to [Migrate from Pydantic v1 to Pydantic v2](https://fastapi.tiangolo.com/how-to/migrate-from-pydantic-v1-to-pydantic-v2/).
