Scala with Cats 2

Two questions come up time and again: "when will the book be updated to Cats 2?", and "when will printed versions be available?" We're happy to say the answer to both is: soon! We have started working on updating the book. In fact the current version of the book, which is linked from the web site, is built against Cats 2 (although it does not discuss new concepts like the Parallel type class). This issue tracks our progress on the update.
