This was always true; this section does ask you to change anything, it just shows you (" Rails has already preconfigured the development and test environments for you to use Active Storage. … take a peek") where these definitions are. That being said, the title of the section and a few places give the impression that you need to take an active role; I’ve adjusted/eliminated those; and added a pointer into the new section within the deployment chapter that will show up in the next beta where you actually will be adjusting this for production.

Thanks!
