PlayStation 4's latest firmware update is available to download now, but don't expect it to do all that much. According to Sony, system update 5.03 "improves system performance." The patch weighs in at around 375 MB, and it's mandatory to install--just turn your PS4 on and the update should begin downloading automatically.
The new update is minor compared to the latest big patch, version 5.0, which was released in October. That included improvements and new features based around the console's in-built streaming capabilities, as well as an enhanced Friends List, more versatile Quick Menu, and an overhauled parental control features.

In more good news for the system, Sony hinted at PSX that we may be able to change our PSN usernames within a year.
