Grinding Gear Games has published a humongous post detailing Path of Exile's 0.11.0 patch. The content drop is currently scheduled for Wednesday, June 5th, and it looks to include a number of tweaks and rebalances designed to improve your dungeon-crawling gameplay experience.
Among the noteworthy adds are a set of "very difficult goals" called Challenges that look to be some sort of precursor to a full-fledged achievement system. Grinding Gear says it isn't quite ready for proper achievements just yet, but you can think of Challenges as a sort of experiment to see how they might affect PoE's gameplay. There's much more to the update, of course, but you'll need to click through to the game's official website to read it all.
