To get this update, you have to opt in inside your library:

This update brings interface sizing, a new boss and a bunch of content mainly focused on the desert biome/cave. If you don't want any spoilers, I recommend to stop reading here and just find a new desert cave to explore!
Here's a small teaser of where you can find the new boss:
