I'm not sure what method you are using to see newest. I usually hit the search button, which used to always sort by newest. Unfortunately, they have added a "Hottest" sort method which is the default, and you have to switch the search sort to newest to get anything but 5E content to show. In my opinion, the "What's New" page is worthless, and now the search takes an extra step to see what is actually new in the marketplace. Such is progress, I guess.
