PSP firmware 4.05 goes live with new visualizers

Sony's official blog says PSP firmware 4.05, out now, contains "other features" in addition to a couple new music visualizers, but it's not clear what they are, apart from a slightly tweaked XMB animation if you've got a wallpaper set up. Go forth and download -- let us know if there's anything earth-shattering in there, won't you?
