It was a person here:
link who wrote: "The old home button is gone, replaced with the word. Advertising screen is absent. Lower screen has Browse Kobo option on left or tips on the right. Center screen has My Books on left and An Author selection on right. Top of screen gives selection of four books you are reading. Upper left corner has Home and this brings you to all menu buttons."
Based on his comment "The advertising screen is absent" I thought perhaps the newer home screen had been modified in this latest update.
