Version 3.0:
Now supports the upcoming new lesson, review, and extra study pages
WaniKani is planning to switch tomorrow to Turbo for providing the lesson, review, and extra study pages. I am not too confident that I managed to iron out all the bugs in this version. As always, please report problems right away.
