While we have worked a lot on HyperRogue recently, we concentrated mostly on experimental features; for people interested in the classic, core non-Euclidean puzzle-roguelike gameplay, the most interesting thing is probably the lands, and there have been no new lands for some time. Version 11.3 includes three new lands, and has many other feature and improvements!
