This update is focused on decorative elements. There are a bunch of new items you can craft, such as furniture, light fixtures, and some outdoor elements. There is a new system which allows customizing the surface of most of these new items...in other words, changing the color and sometimes other aspects of the surface. Also, players can customize the colors of individual lights they create. Mostly unrelated to this, there is also a new upgrade Tier for player inventory (both your personal inventory and the storage locker), which results in 24 item slots.
All of this should allow you to make your home on Syrinx a bit more cozy and personalized!
