Hopefully it fixes a issue introduced in the last patch(controllers randomly disconnecting while playing on full charge every 1.5 Hours)
I think is not widespread issue. Never experienced anything like that.
I can say it fixed it no longer getting random control disconnects on pro
Hmmmmmmm another "blanketed" fix on what and how it does it. I mean it is no issue here, but I would love to know the specifics of how and why this update was especially needed.
"To improve stability" silly, well until it gets hacked AGAIN of course
