Basically it now allows the manufacturers to put bigger logo's on bowls and remove the outer rings etc. I misunderstood it myself initially kakadu till Major Ball and others alerted me to what it mean, as i'd seen these pictures from Taylor Bowls out a month or so doing the rounds. I guess they had some bowls ready and were just waiting world bowls to approve the changes, which they have done.
I initially thought it was removing the discs from the non bias side, but this is what it about.

So it just the manufacturers wanting to change the outer rings and in some cases removing them to fit larger logos or whatever on bowls i gather.
