@immi101
Thanks for the reply. Yes, mrkgnao had experienced blocking issues several times, but that's not what I had in mind.
adaliabooks: Yeah, see what immi101 says below. It's possible to get it, but I'd have to call the changelog url (or the actual downloads) for every product on your library page. With 100 products you might just be ok... but with all products on one page you'd almost certainly crash your browser and / or get locked out of Gog for a few hours..
But I'll have a poke about and see if the changelog info is already present on the page or is called each time you open a new one (I think this is the case) or if there is any other info that would do the trick hidden about.
The download files do have a 'date' field, but it's always empty :/
I'll have a poke about with the notification system too and see if there's anything there that might help, though I'm fairly sure it's mostly server side...
I looked below, there's nth there but the Quick Post box. ;-P
I was thinking more along the lines of getting that info from MaGog instead of DDOS-ing GOG, but I admit that I don't know if that would be even doable or any better of a solution.
Also keep in mind, that there are cases where files get updated without a changelog being added to the user-accounts.
It'd best, for a number of reasons, if GOG provided this feature natively, and they should have already. But it looks to be one more of those "low priority" things for them, so I appreciate you looking into it.
