This patch just has a single change which I am sure most people care very little about. The swinging platforms in The Dark Dungeon weren't resetting on level reset. While for most people this isn't a big deal a couple of people have been trying to speedrun it and timings are important! They actually have a leaderboard here
Watching them push the limits of what is possible is absolutely crazy. If you enjoy this give their channels a follow, they both do other games too!
