There is not a lot in terms of content, just a better structured game internally. But uhh there's an option to turn on female bard now, and a new playable clown girl, plus couple new day-aspects. Game also loads everything much faster now so you don't have to wait for the black screens to fade and unfade every time for a whole ass second.
What got the most work is mod support, I was restructuring the game so that it's super easy to add custom animations, custom playable characters, new outfits, hats, haircuts and etc. I'll make an example mod and a modding guide probably so people can mess around with the game.
With how the game functions now - it's entirely possible to make a mod that adds a character creator menu or something along the lines.
