I signed up to receive the PDF on Jul 19, 2019. The same day, I received the link to the PDF dated Feb 1, 2019 - v3.3.3. It contains a lot of outdated information and it took me a while to realize that the online version is very different, especially in the section: “Set up the Serverless Framework/Add support for ES6/ES7 JavaScript.”
I realize that this is a living document that changes often. I’d be happy to help generate new versions of the PDF but I don’t have access to a Mac. Are you planning to update it soon?
