* Update golang/x/net dependency to bring in fixes for CVE-2019-9512, CVE-2019-9514 ([#81525](https://github.com/kubernetes/kubernetes/pull/81525), [@cblecker](https://github.com/cblecker))
* cpuUsageNanoCores is now reported in the Kubelet summary API on Windows nodes ([#80176](https://github.com/kubernetes/kubernetes/pull/80176), [@liyanhui1228](https://github.com/liyanhui1228))

  If the `DeclarativeValidation` feature gate was enabled, mismatches with existing validation are reported via metrics.

# Conceptos de Implementación { #deployments-concepts }

Cuando implementas una aplicación **FastAPI**, o en realidad, cualquier tipo de API web, hay varios conceptos que probablemente te importen, y al entenderlos, puedes encontrar la **forma más adecuada** de **implementar tu aplicación**.

Algunos de los conceptos importantes son:

* Seguridad - HTTPS
* Ejecución al iniciar
* Reinicios
* Replicación (la cantidad de procesos en ejecución)
* Memoria

      /** The executor on which this Callable will be scheduled. */
      private final ScheduledExecutorService executor;

      /**
       * The service that is managing this callable. This is used so that failure can be reported
       * properly.
       */
      /*
       * This reference is part of a reference cycle, which is typically something we want to avoid

    * It's mainly syntax sugar, a convenience for developer experience.
    * Now `Request`, `Response`, `WebSocket`, `status` can be imported directly from `fastapi` as in `from fastapi import Response`. This is because those are frequently used, to use the request directly, to set headers and cookies, to get status codes, etc.
