Sony has just rolled out a new PlayStation 5 firmware update, PS5 system software update 21.01-03.21.00.

As with most PlayStation firmware updates nowadays, the release notes for this update only mention improved system performance. If enabled, the new system update will automatically be downloaded to the console. The new firmware version can also be downloaded manually via the PS5's system settings ( Settings > System > System Software > System Software Update).
