Developer VVildcard777 has updated his 4.05 PS4Hen to support firmware 4.55 (Download links below).
If you’re getting confused, this is normal. You now have two options to run a Homebrew Enabler (HEN) on your PS4: Holy Grail from m0rph3us1987, or VVildcard777’s version released today. (Update: there’s actually a third option, XVortex‘s PS4Hen is also open source and can be found here)
In practice, for most people, these two different versions will not make a difference for now, so if you had no big problem with Holy Grail, there’s probably no good reason to switch now.
However, in the long run, VVildcard777’s PS4Hen is open source, while Holy Grail isn’t. Having an open source version of the PS4Hen could bring faster improvements to the scene ultimately. Especially given some of m0rph3us1987’s recent statements.
