A new update has been released for Mario Kart World, which includes the addition of a Bob-omb Blast Battle mode. The update also appears to include various fixes and changes, such as balancing tweaks, bug fixes, and adjustments to the probability of items obtained from item boxes. The exact scope of the changes is unclear, but they seem to include additional routes and may have undergone further refinement in a subsequent version 1.6.1 update.
