Sony has started pushing PS4 firmware 6.72 to PS4 consoles worldwide, a few hours ago.

PS4 6.72 and hacks. Should you update?

As always with such a minor release, not much is known about the update. It is not clear whether this actually patches an undisclosed exploit, or if it just brings some urgent patch for a specific game. Furthermore, at the time of publishing, Sony haven’t updated their official firmware page and 6.71 is still mentioned as the latest update.

We advise for people who want to hack their console to stay on as own a firmware as they possibly can, until we hear more details from hackers. The highest hackable firmware (publicly) is 5.05/5.07. (Check more details on our PS4 Jailbreak page)

PS4 6.71 and 6.70

The previous update, 6.71, was released on June 4th, 2019. A few days before that, 6.70 had been released but these firmware updates did not bring any significant changes.

For people not looking to hack their PS4, it is likely you will have to update to 6.72 in order to retain online service access for your console (PSN, etc…). For others, as stated above, we recommend not to update.
