You have to click on 'New Releases' up at the top (nearest to 'Comixology' logo), then scroll down to the sixth line down to 'All New Releases'.
While it's a pain in the butt to find it, I do like that you can go back to previous weeks with it, and filter by publisher.
But finding my library is even more of a hurdle. lol
'View your library' should be on that top menu, as well. Not hidden in the account info page.
