The latest Diablo 3 patch 2.4.3 or 1.15 on console now adds support for the PS4 Pro. The patch notes mention that 4K support was added but the resolution specs were not released in the notes.

For those who are running on a 1080p display, you will see improvements to the resolution with less jagged edges with multiple users on NeoGaf and Reddit reporting the clearer images on HD Tvs.

The patch also included a new dungeon which is a recreation of a Diablo 1 level, enemy improvements, boss tweaks and a number of changes to items, Greater rifts and bounties.
