### Upgrades

* ⬆️ Upgrade Starlette to 0.25.0. PR [#5996](https://github.com/tiangolo/fastapi/pull/5996) by [@tiangolo](https://github.com/tiangolo).
    * This solves a vulnerability that could allow denial of service attacks by using many small multipart fields/files (parts), consuming high CPU and memory.
    * Only applications using forms (e.g. file uploads) could be affected.

### Swagger UI y `examples` específicos de OpenAPI { #swagger-ui-and-openapi-specific-examples }

Ahora, como Swagger UI no soportaba múltiples ejemplos de JSON Schema (a fecha de 2023-08-26), los usuarios no tenían una forma de mostrar múltiples ejemplos en la documentación.

Para resolver eso, FastAPI `0.103.0` **añadió soporte** para declarar el mismo viejo campo **específico de OpenAPI** `examples` con el nuevo parámetro `openapi_examples`. 🤓

will fail early. The default value is `httpcookiemaxnum=3000`. Setting
`httpcookiemaxnum=0` will allow the cookie parsing to accept an indefinite
number of cookies. To avoid denial of service attacks, this setting and default
was backported to Go 1.25.2 and Go 1.24.8.

Go 1.26 added a new `urlmaxqueryparams` setting that controls the maximum number

Il y a quelque temps, [un utilisateur de **FastAPI** a demandé](https://github.com/fastapi/fastapi/issues/3#issuecomment-454956920) :

> Quelle est l'histoire de ce projet ? Il semble être sorti de nulle part et est devenu génial en quelques semaines [...].

Voici un petit bout de cette histoire.
