PS4 is updated to improve its system performance

Firmware 4.55 for Sony's desktop game console is now live.

A new update is now available for PS4, one that brings PlayStation-branded hardware to its version 4.55, and that in exchange for just 324MB allows us to improve some elements of its operation.

By Sony, and in a rather vague message, they limit themselves to clarifying that this "software update improves the quality of system performance", and comes after the firmware patch 4.50 that was released in early March.
