Despite my efforts, I have not been able to get the digital files finished on time. It turns out making a quite a lot of tiny illustrations takes quite a lot of time. I was hoping to get this done so I can get the digital release done before a trip I'm going on, but I've fallen short.
This doesn't affect the physical shipping date (the files are already with the printer), but it does mean the digital release will have to wait until I get back later this month. To tide you over during the wait, here are some mock-ups of both the new modules.
Thank you for your patience, and see you soon with the digital release.
