- 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

- RemoteCommand feature gates for kubectl exec, cp, and attach over WebSockets are now enabled by default (Beta):
  - Server-side feature gate: `TranslateStreamCloseWebsocketRequests`
  - Client-side (kubectl) feature gate: `KUBECTL_REMOTE_COMMAND_WEBSOCKETS`

- 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]

* 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))

* 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.
