Sony Interactive Entertainment just made its newest PS4 system software update numbered 5.00 and code named "Nobunaga" available for download on the PSN.

The update requires 347.4 megabytes of your bandwidth, and this time it's a major one.

Among the new features included in the update are an overhauled family system, better friend list management (including the ability to follow anyone), improved broadcast features, messages and notifications, team tournaments, virtual surround sound for PlayStation VR and more.

It's worth mentioning that unlike small incremental updates, this one is mandatory, and you'll be prompted to update as soon as you connect to the PlayStation Network.

At the moment of this writing the update isn’t available yet on the relevant websites, and and you’ll need to take advantage of the option in the settings of your PS4 or PS4 Pro to launch the download and installation. Later today you should be able to  download it from here if you’re in North America and from here if you’re in Europe.

The latest sizable update to the PS4 system software was released in March, and was numbered 4.50. It included external HDD support, Boost Mode for PS4 Pro, custom wallpapers, and more.

You can find the full patch notes of the update in the gallery below.
