You were probably here for the first fan art update, but if you weren't then we received that update which added a bunch of content to the game.
This new update has added even more content - new skins, guns, decorations, triggers, and some very nice features for the level editor, such as being able to upload custom decorations. There's definitely more than what I listed that is being added in the update, and I believe some work on multiplayer will be finished soon. Stay tuned.
Anyway if you'd like to test out some of the upcoming content, click here:
