Fillable Forms in PDFs / Chapter Availability
Someone was asking me if chapter 16 was available and it made me realize that I didn't mention it was up and ready to enjoy. If you are in doubt, just go to the book's Leanpub page (https://leanpub.com/reportlab) where it will say when the book was last updated. I sometime lag a bit updating Gumroad as that isn't automatic like it is with Leanpub.
Also if you want, please check out chapter 16 and give me some feedback. I wasn't able to get the pdfforms or PdfJinja to work on any of the machines I tried them on, so the coverage of those packages (which I think are the most promising) are lighter than I would like. If you happen to discover what I was missing, let me know ASAP and I will update the chapter.
