The biggest change to this version is a shift from the CC-BY-SA 4.0 license to just CC-BY 4.0.  I've had to chance to learn a bit more about licensing since I first released the game and felt that was the right move to make.

In anticipation of the potential physical release of The Librarian's Apprentice, I've also gone through and made a few tweaks to some clean things up.  No actual content was added or removed.
