@d0gg0d I fucking wish! No, you can look at the products docs page to check if any updates have been passed through but it's generally just a way to document the products changelog for Daz. I don't think they'd ever produce a way to get updates announced or even searchable when it's something that their Install Manager does automatically for legitimate purchases.
...Of course there might be a way to fool the IM into checking the database, like a "scraper" but I'm not tech savvy enough to know for sure. Or maybe there could be a way for a scraper to be produced that would harvest the update information on requested products?
