kubelet now handles WebSocket-to-SPDY stream translation (exec/attach) and WebSocket tunneling (portforward) using the same handlers previously used at the API server. The kubelet advertises support for this feature to the API server via the NodeDeclaredFeatures mechanism; the API server only proxies directly to a kubelet that has advertised support. Two new ALPHA metrics are added to track routing decisions and WebSocket streaming volume: apiserver_websocket_streaming_requests_total (labels: subresource,...

  
    A previous release built hyperkube using the debian-hyperkube-base@v1.0.0,
    which was updated to address a CVE in the CNI plugins.
    
    A side-effect of using this new image was that the networking packages
    (namely `iptables`) drifted from the versions used in the kube-proxy images.
  
    The following issues were filed on kube-proxy failures when using hyperkube:

  - Clone `kubernetes/kubernetes` in `update-vendor.sh` shallowly, instead of fetching all revisions
  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric

# Directory Leasing Feature - Detailed Design Document

## 1. Overview

Directory leasing extends the SMB3 lease concept to directories, enabling client-side caching of directory metadata and change notifications. This significantly improves performance for applications that frequently enumerate directories or monitor directory changes.

## 2. Protocol Specification Reference

- **MS-SMB2 Section 2.2.13.2.12**: SMB2_CREATE_REQUEST_LEASE_V2 for directories

		}

# Request'i Doğrudan Kullanmak { #using-the-request-directly }

Şu ana kadar, ihtiyacınız olan request parçalarını tipleriyle birlikte tanımlıyordunuz.

Verileri şuradan alarak:

* path'ten parameter olarak.
* Header'lardan.
* Cookie'lerden.
* vb.

Bunu yaptığınızda **FastAPI**, bu verileri doğrular (validate eder), dönüştürür ve API'niz için dokümantasyonu otomatik olarak üretir.

# Using the Request Directly { #using-the-request-directly }

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

# Utiliser Request directement { #using-the-request-directly }

Jusqu'à présent, vous avez déclaré les parties de la requête dont vous avez besoin, avec leurs types.

En récupérant des données depuis :

* Le chemin, sous forme de paramètres.
* En-têtes.
* Cookies.
* etc.

Et ce faisant, **FastAPI** valide ces données, les convertit et génère automatiquement la documentation de votre API.

# 直接使用 Request { #using-the-request-directly }

到目前為止，你都是用對應的型別來宣告你需要的請求各部分。

例如從以下來源取得資料：

- 路徑中的參數。
- 標頭。
- Cookies。
- 等等。

這麼做時，FastAPI 會自動驗證並轉換這些資料，還會為你的 API 產生文件。

但有些情況你可能需要直接存取 `Request` 物件。

## 關於 `Request` 物件的細節 { #details-about-the-request-object }

由於 FastAPI 底層其實是 Starlette，再加上一層工具，因此在需要時你可以直接使用 Starlette 的 [`Request`](https://www.starlette.dev/requests/) 物件。
