## Full Stack FastAPI Template - Pilha de Tecnologias e Recursos { #full-stack-fastapi-template-technology-stack-and-features }

- ⚡ [**FastAPI**](https://fastapi.tiangolo.com/pt) para a API do backend em Python.
    - 🧰 [SQLModel](https://sqlmodel.tiangolo.com) para as interações do Python com bancos de dados SQL (ORM).

* Fixes an issue with upgrade requests made via pod/service/node proxy subresources sending a non-absolute HTTP request-uri to backends ([#52065](https://github.com/kubernetes/kubernetes/pull/52065), [@liggitt](https://github.com/liggitt))

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
