Version 11? Last time I checked they where at 4. Are they using semantic versioning? If yes, that many major versions is a red flag.

- v8: we added functions and streams. It basically changes everything. We also added asynchronous stuff but you don’t care yet.
- v11: we added built-in async http. Now you really want to have a look at that asynchronous stuff from v8.
And that’s pretty much it.
