For those who recently bought Builder Book or are planning to buy it soon - note that as part of our May update, we will upgrade Material-UI and Next.js from the beginning of the book. We currently upgrade those packages at the end of the book.

This will only impact syntax in some of your files. It will not change the concepts you learn, so please don't hesitate to start reading :)
