0.89.0

Features

• ✨ Add support for function return type annotations to declare the response_model. Initial PR #1436 by @uriyyo.

Now you can declare the return type / response_model in the function return type annotation:

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    price: float


@app.get("/items/")
async def read_items() -> list[Item]:
    return [
        Item(name="Portal Gun", price=42.0),
        Item(name="Plumbus", price=32.0),
    ]

FastAPI will use the return type annotation to perform:

• Data validation
• Automatic documentation
  • It could power automatic client generators
• Data filtering

Before this version it was only supported via the response_model parameter.

Read more about it in the new docs: Response Model - Return Type.

0.87.0

Highlights of this release:

• Upgraded Starlette
  • Now the TestClient is based on HTTPX instead of Requests. 🚀
  • There are some possible breaking changes in the TestClient usage, but @Kludex built bump-testclient to help you automatize migrating your tests. Make sure you are using Git and that you can undo any unnecessary changes (false positive changes, etc) before using bump-testclient.
• New WebSocketException (and docs), re-exported from Starlette.
• Upgraded and relaxed dependencies for package extras all (including new Uvicorn version), when you install "fastapi[all]".
• New docs about how to Help Maintain FastAPI.
