The PlayStation 4 has seen a number of updates since the last major update in March of this year and it has just received yet another update. Unlike March's Yakimura update that brought a number of new features, this update is much more toned down.
Similar to the previous update to the system this update will be looking to add stability to the PS4. Sony has revealed that the update will bring stability improvement"during use of some features," that's all.
The update shouldn't take long, the file size is around 245MB and will automatically begin downloading once you turn on your PS4. The update is now available for download (it should be titled Version 2.57).
