This week's League of Legends patch introduces a brand new champion, and some updates to a number of champions, including Sona, Soraka, Shen and Vladimir.
Nautilus is the new champ, and Riot are introducing a new initiating ability to the game with Nautilus' Dredge Line, which pulls both himself and the enemy towards each other. In addition, Sona's getting a nerf, affecting her abilities early-game. Shen, Soraka and Vlad are getting a number of changes as well that will supposedly introduce a better balance in team comps.
