v1.48.0

## WebSocket routing

New methods [page.routeWebSocket()](https://playwright.dev/docs/api/class-page#page-route-web-socket) and [browserContext.routeWebSocket()](https://playwright.dev/docs/api/class-browsercontext#browser-context-route-web-socket) allow to intercept, modify and mock WebSocket connections initiated in the page. Below is a simple example that mocks WebSocket communication by responding to a `"request"` with a `"response"`.

```js
await page.routeWebSocket('/ws', ws => {
  ws.onMessage(message => {
    if (message === 'request')
      ws.send('response');
  });
});
```

See [WebSocketRoute](https://playwright.dev/docs/api/class-websocketroute) for more details.

## UI updates
- New "copy" buttons for annotations and test location in the HTML report.
- Route method calls like [route.fulfill()](https://playwright.dev/docs/api/class-route#route-fulfill) are not shown in the report and trace viewer anymore. You can see which network requests were routed in the network tab instead.
- New "Copy as cURL" and "Copy as fetch" buttons for requests in the network tab.

## Miscellaneous
- Option [`form`](https://playwright.dev/docs/api/class-apirequestcontext#api-request-context-fetch-option-form) and similar ones now accept [FormData](https://playwright.dev/docs/api/class-formdata).
- New method [page.requestGC()](https://playwright.dev/docs/api/class-page#page-request-gc) may help detect memory leaks.
- New option [`location`](https://playwright.dev/docs/api/class-test#test-step-option-location) to pass custom step location.
- Requests made by [APIRequestContext](https://playwright.dev/docs/api/class-apirequestcontext) now record detailed timing and security information in the HAR.
