Article says what the patch does Yay “ A new update has been deployed following the recent XP progression fixes with additional improvements across both titles, including:
Public Multiplayer matches will now prioritize PS5 hosts and no longer fall back to PS4 hosts
Additional protections against host migration workarounds
Controller deadzone behavior updated to align with the original PS3 versions
Note that XP exploits and issues might not be fully resolved yet, but the studio has confirmed they will implement additional fixes in the future.”
The article says more than I put here finally something is being done also the dead zone issues seem to be. Better it claims
