* kube-apiserver: fixed a bug that could cause a goroutine leak if the apiserver encountered an encoding error serving a watch to a websocket watcher ([#84693](https://github.com/kubernetes/kubernetes/pull/84693), [@tedyu](https://github.com/tedyu))

- Fixes a 1.30+ regression in connection stability for exec / attach / portforward requests initiated using a websocket client ([#130253](https://github.com/kubernetes/kubernetes/pull/130253), [@fuweid](https://github.com/fuweid)) [SIG API Machinery, CLI and Testing]

Il utilise le standard précédent pour les frameworks web Python (WSGI) qui est synchrone, donc il ne peut pas gérer les WebSockets et d'autres cas d'utilisation. Néanmoins, il offre de très bonnes performances.

Il est conçu pour avoir des fonctions qui reçoivent deux paramètres, une "requête" et une "réponse". Ensuite, vous

- Fixes issue with websocket-based watches of Service objects not closing correctly on timeout ([#102541](https://github.com/kubernetes/kubernetes/pull/102541), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

## Dependencies

- Enabled feature gates for PortForward (kubectl port-forward) over WebSockets by default (beta).
   - Server-side feature gate: PortForwardWebsocket
   - Client-side (kubectl) feature gate: PORT_FORWARD_WEBSOCKETS environment variable

* Досконаліші (але однаково прості) техніки для оголошення **глибоко вкладених моделей JSON** (завдяки Pydantic).
* Багато додаткових функцій (завдяки Starlette) як-от:
    * **WebSockets**
    * надзвичайно прості тести на основі HTTPX та `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ...та більше.
