 Check out [the `check` utility function's documentation](https://grafana.com/docs/k6/latest/javascript-api/jslib/utils/check/) for more information on how to use it.
+### `k6/experimnetal/websockets` updates towards WebSockets API compatibility
 
-### Support ArrayBufferViews in `send` for `k6/experimental/websockets` [#3944](https://github.com/grafana/k6/pull/3844)
+#### Support ArrayBufferViews in `send` for `k6/experimental/websockets` [#3944](https://github.com/grafana/k6/pull/3844)
 
 As part of making `k6/experimental/websockets` compliant with the [WebSocket API](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket), it now supports Uint8Array and other ArrayBufferViews directly as arguments to `send`, instead of having to specifically provide their `buffer`.
 
 This should make the module more compliant with libraries that use the WebSocket API.

+#### `readyState` actually being a number [#3972](https://github.com/grafana/k6/pull/3972)
 
+Due to goja/Sobek internal workings, `readyState` wasn't exactly a number in JavaScript code. This had some abnormal behavior, which limited interoperability with libraries.
+
+This has been fixed, and `readyState` is a regular number from the JavaScript perspective.
