PS4 update 5.01 has been released by Sony, which appears to be another stability update.

Like most recent PS4 system software update, release notes are minimal, and only mention improved system performance. Whether the firmware update addresses issues that have been reported following the PS4 5.0 update, including the dreaded error code e-801809a8, is unsure at this point.
