For the PlayStation 4, the PS4 Firmware 5.53 was released, which apparently makes no major changes or brings features to the console. The official changelog can only be deduced that the stability of the system was screwed.
Sony has released a new firmware for the PlayStation 4, which raises the system to version 5.53. The download has a size of more than 400 MB, but it is not clear which changes are made in the background. New features were apparently not added, because Sony refers only to an improvement in system performance. The wording reads: “This system software update improves system performance.” This is a standard statement for minor updates that do not bring any new features.
The PS4 Firmware 5.53 is available worldwide and can be downloaded as usual via the system update. Soon, the download should also be available on the official site, so you can take a detour via a PC and import the update manually if necessary. About a month ago, the larger PS4 Firmware 5.50 was released, which brought significantly more new features. These include cross-supersampling, kids time control, UI changes, USB wallpaper import, and other features.
A few days ago, a new firmware update was released for the PS Vita, which raises the handheld to version 3.68. Also to this firmware no noteworthy information was published. According to speculation, this was an exploit closed.
