 ## ⚠ Breaking Changes
 
-- Minimum supported `Node.js` version is `20.9.0`.
+- Minimum supported `Node.js` version is `22.15.0`.
 - Minimum supported `webpack` version is `5.101.0`.
 - Support for **SockJS** in the WebSocket transport has been removed. Now, only **native WebSocket** is supported, or **custom** client and server implementations can be used.
 - The options for passing to the `proxy` have changed. Please refer to the [http-proxy-middleware migration guide](https://github.com/chimurai/http-proxy-middleware/blob/master/MIGRATION.md) for details.
-- Remove support for the spdy server type. Use the http2 server type instead; however, since Express does not work correctly with it, a custom server (e.g., Connect or Hono) should be used.
