Blizzard has patched Diablo III to version 2.0.4 in the Americas. There are a decent number of class tweaks in the patch as well as an adjustment to the drop of unique legendary crafting materials. They've been "significantly increased," if you're wondering.
There are a few itemization changes, too, including an adjustment to to treasure drops from resplendent chests. "The treasure from Resplendent Chests has been improved to feel more resplendent," Blizzard says.
