PS4 Software Update 4.05 Released October 25, 2016Posted by Maniac in Game News.
A required software update, version 4.05, was released for the PS4 earlier today. The new update is very vague about what it does, meaning that it probably adds no new features and only includes bug fixes and optimizations for the PlayStation 4 hardware.
If you had the previous software update installed, this new update should only weigh in at around 350MB. You MUST install the update to access the PlayStation Network.
