Which versions of node.js are available on Azure Web Sites?

Question

I already know how to change the version of Node.js running on an Azure website, but how do I see what the available Node.js version are that can be used in Azure?

This is similar to this question, but the asker there explicitly wants to know the version that is currently running, not what versions are available.
