I noticed that in my Library on the new store, a fair number of PDFs have a 'last updated' date that is fairly recent... e.g. Thirst for Blood (book 1 of Shades of Blood) has a last updated date of 12/31/25, the Starfinder Galaxy Guide says 12/24/25, and Starfinder Alien Core says 1/2/26. This feels much more frequent than when PDFs would get updates on the old store's digital content page. Is there a way to know what changes have been made, or to get notified of updated versions being uploaded so that we know to go redownload them? Or are the dates listed here in error and the file actually hasn't been changed?
