I don't talk about it a lot, but I use ubuntu for my home server and for my development machines at work. So I was fairly excited about the latest release coming out today. I don't usually get it the first day, but decided to do it this time.
Anyway, it's called Quantal Quetzal (the picture that goes with it is based on the resplendent quetzal. I should really look it up, but I assume the name is an aztec one (they have a god named quetzalcoatl, a bird-snake, IIRC). The bird looks like this; pretty neat.
I haven't done much with it, it's only on my server box, but I'm looking forward to finding out. I especially want to know about juju, which sounds nifty.
