GPT-4 API. Is "openai" NPM package updated for this?

I just got accepted into the GPT-4 API beta. Has the official “openai” NPM package for Node.js been updated to be able to call the brand new GPT-4 API endpoint? If not, where do I find sample code or a library that does that for me or shows me how to do that, or do I have code my own from scratch?

Also, is this the API endpoint for ChatGPT-4 to? Or is that still not available yet?
