I really don't understand why they even did that? Guess the web devs got too bored while the current one worked too well, but that should have maybe been a sign to keep your hands from it.
You don't even need to be a designer to see how it looks worse even if you are not able to point out what exactly is wrong.
Especially do not get why they got rid of the borders for the sake of minimalism. It adds so much unnecessary mental overhead.
