Looking to get into Pathfinder but am confused as to which core rule book is the new "Remastered" version.

So I did some research and they just released a new "Remastered" version of 2E but I don't see anything on the front covers of any of these books that explain which is the Remastered and which isn't. I'm thinking of getting the core or GM rulebook just to study by myself for fun for the time being. Also interested in any lore books. Thanks
