    # TODO: needed by asyncio in Python 3.9.7 https://bugs.python.org/issue45097, try to remove on 3.9.8
    'ignore:The loop argument is deprecated since Python 3\.8, and scheduled for removal in Python 3\.10:DeprecationWarning:asyncio',
    'ignore:starlette.middleware.wsgi is deprecated and will be removed in a future release\..*:DeprecationWarning:starlette',

!!! note "Technical Details"
    It used <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a> instead of the default Python `asyncio` loop. That's what made it so fast.

    It clearly inspired Uvicorn and Starlette, that are currently faster than Sanic in open benchmarks.

    Find a way to have a crazy performance.

## 0.47.1

* Fix model filtering in `response_model`, cloning sub-models. PR [#889](https://github.com/tiangolo/fastapi/pull/889).
* Fix FastAPI serialization of Pydantic models using ORM mode blocking the event loop. PR [#888](https://github.com/tiangolo/fastapi/pull/888).

## 0.47.0

!!! note "Detalhes técnicos"
    Ele utiliza <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a> ao invés do '_loop_' `asyncio` padrão do Python. É isso que deixa ele tão rápido.

    Ele claramente inspirou Uvicorn e Starlette, que são atualmente mais rápidos que o Sanic em testes de performance abertos.
