I don't know if GOG already has this feature. But I would like it if we could get emails when our games get patches and other new things. I do know that when we go to the site we get a little red notification about updates. But why not just send an email.

You might want to vote for one of [url=http://www.gog.com/wishlist/site/email_notification_of_new_patch_update_for_owned_game]wishlist items.

There may be more but I found those almost immediately.
