the "release" is what you find in systems/texlive/Images

as expected (modulo exaggeration: there was nothing new overnight last
night -- i know because all ctan distribution comes through my archive).

tex live is a *live* system.  when it was first released, its liveness
was no more than release a year.  nowadays, after the (nominal) yearly
release, there are patches regularly available.  for some people, that's
an advantage.

so take the dvd images and install from them.

and most operating system distributions come with tex live 2007, taken
from a snapshot some time back.  (there's a tl2008 rpm in the fedora
distribution, but we've not managed to get it going here, yet.)

if you can't do the obvious thing and use the os distributed tex (e.g.,
if you're not using an os distribution that provides tex), go with the
original tex live release.

in summary, if you want something static, go for something static, and
don't go in for the dynamic service.
