Steam has detailed the new product update required for Torchlight 2.
Patch 188.8.131.52 contains notes about changes to the game's functionality, gameplay, scripting, networking, graphics, and more.
One fix prevents players from "stealing" items from the buyback tab by closing the window with the space bar. Runic Games also addressed crashes and multiplayer problems, such as when "non-killing MP players did not receive appropriate XP falloff due to level delta." The developer also improved skills where needed.
Those are only a few of the many issues that have been resolved. You can read the full list on the Steam blog.
