Comic Life 3.5.12 update for Windows and Mac, released a week ago.
I see that Packt have a pretty good free chapter from one of their how-to-books that goes in-depth on how advanced users can get the most out of setting up Comic Life 3. Unfortunately the PDF utterly lacks metadata or footers/headers, but the number in the file-name reveals it to have been part of their Manga Studio 5 Beginner’s Guide book. Only the expensive Manga Studio EX version has multi-page documents, so presumably that’s why they were suggesting the need to use Comic Life with the budget version of Manga Studio (now Clip Studio).
