“This system software update improves the quality of the system performance”.
Sony has just released an update for the PS4, and as you might have guessed and as is the case for most minor firmware updates, it’s a “stability improvement”, also known on the scene as “we patched some vulnerability”.
There is no word out yet from hackers if this impacts any of the (unreleased) exploits they have access to. A few weeks ago, hacker qwertyoruiop stated he would release his 4.5x hack if and when Sony patches it. Obviously, unless his exploit actually leaked to Sony, it is very unlikely that this is what this update is about.
There was however a recent announce about a critical Linux/FreeBSD vulnerability (stack clash), which, based on the timing of this release, could be related. Of course to be sure we’d have to wait for a statement from PS4 hackers out there.
As always, people looking forward to homebrew on their PS4 should stay on as low a firmware as they possibly can.. In my case, I have bought a second PS4 (a PS4 Slim) as my main gaming rig, while my other PS4 patiently waits for homebrew.
