Esto incluye, por ejemplo:

* Notificaciones por email enviadas después de realizar una acción:
  * Como conectarse a un servidor de email y enviar un email tiende a ser "lento" (varios segundos), puedes devolver el response de inmediato y enviar la notificación por email en segundo plano.
* Procesamiento de datos:

Allí puedes seleccionar "Releases only".

Al hacerlo, recibirás notificaciones (en tu email) cada vez que haya un nuevo lanzamiento (una nueva versión) de **FastAPI** con correcciones de bugs y nuevas funcionalidades.
