Focus was placed around the brig and maintenance areas, but a number of smaller changes are also present all around the station. I'll try to list as many as I can.

-Expanded maintenance areas. New room "Electrical Maintenance" added.
-Brig partially remapped to better resist greytide attacks, as well as provide a more natural passageway to the labor shuttle
-Labor Securitron defaults to off because officers often left the prisoners on arrest, making them unable to work their quota off
-Emergency shuttle redesigned to encourage more orderly conduct. Includes new cargo and security areas.
-Replaced all white airlock doors with real airlocks.
-New public garden area near arrivals
-Moved the Ore Redemption Machine over to the delivery office
-The Misc Research lab returns as the Testing Lab, equipped with a firing range
-Added a list of sorttype codes in comments for easy reference
