The main concept remains the same, but I will tell you the differences between that version and this current one.
Instead of using the gather node, the conversation node is "say" and "gather" put together. It has a section called "extract variables" that does the same thing as gather. The condition node is now part of the line that connects two nodes together.
Start with a workflow template and you'll see what I mean. If you have any other questions, let us know.
