Huh, you're right; Wikipedia puts the EOL of the current version at 2025-12-31. I wonder if they changed that or I misremembered; I was quite sure that I'd read of it being EOLed years ago. (Or perhaps I did read an EOL notice but they were announcing it on Enterprise timelines, i.e. "heads up that it'll finally die in a mere 8 more years"...)
It’s only on Itanium hardware now which is super dead, which limits the ability for anyone to experience it
Um. So I think you're the first person I've ever encountered who had anything good to say for it. I never had the pleasure, so I'm working from second-hand accounts; what was good about it?
One nice thing was Ignite.
I really missed that, until I found ReaR.
I actually passed the HP-UX certification exam.
Coincidentally CDE dropped its support in this very release.
