A new PlayStation 4 update has landed--but it's not the type that adds new features or functionality. Version 5.55, which is mandatory, "improves system performance" in unspecified ways, according to the official patch notes posted by Sony on its website.
"This system software update improves system performance," reads the one-line patch notes.
If you're not automatically prompted to download the update, you can navigate to Settings and then to System Software Update where you will see a button that says Update. It's possible to download and install the update via a USB storage device, too; here's how to do that.
This update follows version 5.50 that was released in March. That was a much bigger update that brought new organizational features, additional parental controls, and a new supersampling option for PS4 Pro, among other things.
In other news, there is still no word on when we'll be able to change our PSN usernames--a feature much-requested by the PlayStation community. However, Sony hinted at PSX that this capability may arrive within the year.
Sony's E3 2018 briefing is coming up early next month. The event will focus on four big games, and Sony has also confirmed there will be no news about hardware--so no PS5 reveal.
