In order to ease the migration to Socket.IO v3, the Engine.IO server
can now communicate with v3.x clients.
```js
const eioServer = require("engine.io")(httpServer, {
allowEIO3: true // false by default
});
```
If `allowEIO3` is false, the v3.x clients will now receive an HTTP 400
response ("Unsupported protocol version").
Note: the code of the v3 parser has been imported from [1] and
browser-related dependencies were removed.
