Steam announces an automatic update is now available for Dungeon Defenders to bring the dungeon crawler to version 7.40 along with the announcement that the new Jester Hero DLC is now available for the game, and will be free-of-charge for the next two weeks. Here's word:

A sly trickster born in a whimsical realm of chaos, the Jester's abilities are shrouded in mystery. She can quickly turn the tide of battle by using any weapon and can deceive enemies with 'presents' that explode to reveal random defenses and bonuses. Her 'Move Tower' ability allows her to adapt defensive strategies and react to any combat situation, while her 'Wheel O' Fortuna' ability can grant boons or decimate friend and foe alike.
