The PlayStation 4 patch is a field dressing. It fixes the "one-hit kill" bug, enables audio in video capture and should fix a crash that occurs when "having a very large amounts of Friends." Let's gloss over the face that a core competence of Battlefield is supposed to be playing with lots of friends.
DICE notes, "We are already working on the next PS4 update that will contain more fixes and have a bigger focus on game stability. Stay tuned."
The Xbox One patch is still planned for this week.
