Two major features have been added, along with other stuff:

-Inventory overhaul - Instead of having number keys select a weapon or item, the weapon/item have been turned into inventory items to be selected instead.

-Persistent worlds - In other words, if your ship gets destroyed, you won’t end up in a new universe. You will however, spawn as you did when you first started - any ores mined will be gone, for instance

-Starter kit - You start off with the basic weapon and mining laser in your inventory

-Refineries - Currently just a target for target practice, the refinery will, in a future update, refine ores or let you sel the ores instead
