A couple of weeks ago it was made clear that the next firmware update for PlayStation 4 would introduce the long awaited Suspend/Resume function, making it possible to start your games right where you left off after putting the console in rest mode.
Today Sony has announced that this update, which is codenamed "Yukimura", will arrive tomorrow.
Alongside the aforementioned Suspend/Resume function Yukimura will provide a vast array of other functions, such as "Back-up and restore HDD to USB" and "Automatic installation for system software updates".
You'll find the complete list of improvements over at the PlayStation Blog.
