I printed off the 2015 version (yes, the whole thing) and it has served as a very valuable reference. I wish there was a way to purchase a nice printed edition to support the authors. If they read this - thanks! Also, is a 2017 version of the course coming to OCW? I imagine that's why they'd release the updated PDF.
Freshman at MIT here taking this class -- the lectures are actually taught in a flipped classroom format, so I wouldn't imagine they would release the course considering there are no lectures to follow. I could see them releasing problem sets, however.
