Posting about it is not quite enough as most user do not visit the site as frequently as some of us so they will easily miss news updates and forum posts about file updates. This if why I made a feature request for upload/update date next to each file so users can easily see when it was last updated.
+1 on that. I would really appreciate that feature.
That'd be even better. In fact, maybe when the Setup exe goes through its "Checking file integrity" procedure, it could automatically query the GOG server to make sure you've got the most recent version of the game.
If you haven't already done so, it's not a bad idea to make this suggestion on the GOG.com Features Wishlist
. The ironic thing about that request is that if it would happen, every installer would be updated in order to support that. :P
