Since their previous revision and the 8.00 PS4 Beta, today Sony pushed live the latest 'system performance' update in PS4 System Software / Firmware 7.55 which many suspect fixes one of the recently reported vulnerabilities in the PlayStation Bug Bounty Program. 
If this is the case, here's to hoping whoever cashed in on it will follow in the footsteps of theflow0 and after getting $ony's approval (disclosure log) publicly release the exploit that lead to the last PS4 Jailbreak so that scene developers can further examine the latest findings.
As always DON'T UPDATE if you wish to use PS4 game backups and homebrew apps whenever a new PS4 jailbreak exploit arrives, and we'll add any related Tweets below as PlayStation 4 scene developers have a chance to examine it.
