Three new loadouts have been added to the roster; The Pirate, The Hacker and The Hustler!
They're filling in some gaps in the progression, so you can unlock them by completing the 1st, 2nd and 3rd weeks of a run (or you can just enable Boss Mode from the options menu if you want to skip straight to it).
There's also a new mod type that might show up from time to time, and it shows up as a starting bonus on The Hustle's loadout.
Finally, there are probably a few minor fixes in there for issues I found while I was working on the new stuff, but I doubt they're particularly important because I can't remember the specifics of any of them.
Happy Mining,
