I got it on my Paperwhite last night, but turned it off within a few minutes. No biggie. Now it's back to the layout it was before, which I like, with only a few minor changes to the menu at the top
I tried to find the answer, but Amazon's confusing - will the Kindle 4 be pushed with the new update or is it outside the time period for which they're releasing it? My old Kindle 4 is always online, able to download updates, but hasn't seen any changes, so I'm not sure if I should expect them considering it's not a touch interface?
