The most noticable additions in the last 2-3 years have been the mansion's detailed slave information panel, the shop sell quantity popup, and the mod system and Constants mod overhauls. There have been various gameplay tweaks like renaming 2 elven races, making rope reusable, and updating human and elf racial bonuses. The game has a change log in the main menu that lists the most significant changes going back many versions. The vast majority of the changes are simply to ensure that most of the game is reliable, so not everything shows up in the change log.
