- Adds feature gate `KubeletInUserNamespace` which enables support for running kubelet in a user namespace.
  
  The user namespace has to be created before running kubelet.
  All the node components such as CRI need to be running in the same user namespace.
  

- Improved logging when volume times out waiting for attach/detach. ([#108628](https://github.com/kubernetes/kubernetes/pull/108628), [@RomanBednar](https://github.com/RomanBednar))
- Improved the rounding of `PodTopologySpread` scores to offer better scoring when spreading a low number of pods. ([#107384](https://github.com/kubernetes/kubernetes/pull/107384), [@sanposhiho](https://github.com/sanposhiho))

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

## Mounting a **FastAPI** application { #mounting-a-fastapi-application }

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

    private final CountDownLatch stopLatch = new CountDownLatch(1);

    private volatile boolean running = false;

    @Override
    public @Nullable Void call() throws InterruptedException {
      running = true;
      startLatch.countDown();
      stopLatch.await();
      running = false;
      return null;
    }

    void waitForStart() throws InterruptedException {

{* ../../docs_src/behind_a_proxy/tutorial004_py39.py hl[9] *}

and then it won't include it in the OpenAPI schema.

## Mounting a sub-application { #mounting-a-sub-application }

## Монтирование приложения **FastAPI** { #mounting-a-fastapi-application }

«Монтирование» означает добавление полностью независимого приложения по конкретному пути; далее оно будет обрабатывать всё под этим путём, используя объявленные в подприложении _операции пути_.

# Benchmarks { #benchmarks }

Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI).
