Yesterday, one new sysytem software of PlayStation 4 was released. As always, the changelog of PS4 5.53 is still one sentence “This system software update improves system performance.”
But Mathieulh confirmed that PS4 5.53 has patched 5.05/5.50 Webkit exploit on his twitter.
The new update allows to choose ow much data you want them to collect from your console. This includes data about online services (which cannot be deactivated), and navigation data (how you use the console. That part can be turned off).
Note: If you want to hack your console in the future, do not update your PS4 and keep it in lower firmware version. Or you do not mind it, just update your console directly.
