Since updating to PS3 4.89 OFW and PSVita 3.74 OFW earlier this week followed by the Remote Kernel Heap Overflow by M00nbsd disclosure and PS5 5.10 OFW, today Sony pushed live a PS4 System Software / Firmware v9.60 Update which once again 'improves' system performance similar to the previous revision. 
As always, DON'T UPDATE if you wish to use PS4 Game Backup PKGs via PS4 Torrents and Homebrew Apps whenever a new PS4 Jailbreak Exploit arrives in the PlayStation 4 Scene.
