And the `dict` you receive as `weights` will actually have `int` keys and `float` values.

## Recap { #recap }

With **FastAPI** you have the maximum flexibility provided by Pydantic models, while keeping your code simple, short and elegant.

But with all the benefits:

* Editor support (completion everywhere!)
* Data conversion (a.k.a. parsing / serialization)
* Data validation
* Schema documentation

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure { #an-example-file-structure }

**OkHttp now supports Happy Eyeballs ([RFC 8305][rfc_8305]) for IPv4+IPv6 networks.** It attempts
both IPv6 and IPv4 connections concurrently, keeping whichever connects first.

**We’ve improved our Kotlin APIs.** You can skip the builder:

```kotlin
val request = Request(
  url = "https://cash.app/".toHttpUrl(),
)
```

{* ../../docs_src/behind_a_proxy/tutorial001_py39.py hl[6] *}

And the proxy would be **"stripping"** the **path prefix** on the fly before transmitting the request to the app server (probably Uvicorn via FastAPI CLI), keeping your application convinced that it is being served at `/app`, so that you don't have to update all your code to include the prefix `/api/v1`.

Up to here, everything would work as normally.

- kubeadm: removed preflight check for nsenter on Linux nodes
  kubeadm: added preflight check for `losetup` on Linux nodes. It's required by kubelet for keeping a block device opened. ([#129450](https://github.com/kubernetes/kubernetes/pull/129450), [@carlory](https://github.com/carlory)) [SIG Cluster Lifecycle]

- The DRA device taints and toleration feature received a separate feature gate, `DRADeviceTaintRules`, which controlled support for `DeviceTaintRules`. This allowed disabling it while keeping `DRADeviceTaints` enabled so that tainting via `ResourceSlices` continued to work.

                # Before this was also used for closing dependencies with yield but
                # those now have their own AsyncExitStack, to properly support
                # streaming responses while keeping compatibility with the previous
                # versions (as of writing 0.117.1) that allowed doing
                # except HTTPException inside a dependency with yield.

* ⬆️ Upgrade OpenAI model for translations to gpt-5.2. PR [#14579](https://github.com/fastapi/fastapi/pull/14579) by [@tiangolo](https://github.com/tiangolo).

## 0.126.0

### Upgrades

* ➖ Drop support for Pydantic v1, keeping short temporary support for Pydantic v2's `pydantic.v1`. PR [#14575](https://github.com/fastapi/fastapi/pull/14575) by [@tiangolo](https://github.com/tiangolo).
    * The minimum version of Pydantic installed is now `pydantic >=2.7.0`.

API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
issue if there is one) requesting the feature and describing specific use cases
for it.

        "race conditions and multiple comments"
