I picked up a print copy of the Deluxe Hero's Handbook a week or so from an online store. I liked it so much I decided to grab a few of the other books in PDF directly from greenronin.com, including a copy of the same Deluxe Hero's Handbook for convenience. However, I just noticed that my hardcopy printing has a 2013-2015 copyright on the front page, while the PDF I just downloaded still has just the 2013 copyright. I had assumed the PDF would be the same or perhaps even more recent than the hardcopy I have, so this seems odd. (One nice thing about DTRPG is that you can see when the PDF has been updated in the sidebar for each title.)
Bottom line... does GR keep the PDFs updated, and if so, how does one get access to revised content?
