## Changes to API Resources
### ABAC
* ABAC policies using `"user":"*"` or `"group":"*"` to match all users or groups will only match authenticated requests. To match unauthenticated requests, ABAC policies must explicitly specify `"group":"system:unauthenticated"` ([#38968](https://github.com/kubernetes/kubernetes/pull/38968), [@liggitt](https://github.com/liggitt))

また、`from starlette.requests import Request`と`from starlette.responses import JSONResponse`を使用することもできます。

**FastAPI** は開発者の利便性を考慮して、`fastapi.responses`と同じ`starlette.responses`を提供しています。しかし、利用可能なレスポンスのほとんどはStarletteから直接提供されます。これは`Request`と同じです。

## デフォルトの例外ハンドラのオーバーライド

**FastAPI** にはいくつかのデフォルトの例外ハンドラがあります。

1.19.13, Go 1.20.8, and Go 1.21.1.

Go 1.22 made it an error for a request or response read by a net/http
client or server to have an empty Content-Length header.
This behavior is controlled by the `httplaxcontentlength` setting.

Go 1.22 changed the behavior of ServeMux to accept extended
patterns and unescape both patterns and request paths by segment.
This behavior can be controlled by the

- Kubeadm: make sure that a variety of API server requests are retried during "init", "join", "upgrade", "reset" workflows. Prior to this change some API server requests, such as, creating or updating ConfigMaps were "one-shot"...
