Snapshot builds are [available][snap]. [R8 and ProGuard][r8_proguard] rules are available.

Also, we have a [bill of materials (BOM)][bom] available to help you keep OkHttp artifacts up to date and be sure about version compatibility.

```kotlin
    dependencies {
       // define a BOM and its version
       implementation(platform("com.squareup.okhttp3:okhttp-bom:4.12.0"))

## 未来

至此，**FastAPI** 及其理念已经为很多人所用。

对于很多用例，它比以前很多备选方案都更适用。

很多开发者和开发团队已经依赖 **FastAPI** 开发他们的项目（包括我和我的团队）。

但，**FastAPI** 仍有很多改进的余地，也还需要添加更多的功能。

总之，**FastAPI** 前景光明。

There are also some **company-backed** Client and SDK generators based on OpenAPI (FastAPI), in some cases they can offer you **additional features** on top of high-quality generated SDKs/clients.

Some of them also ✨ [**sponsor FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨, this ensures the continued and healthy **development** of FastAPI and its **ecosystem**.
