Maybe this is a dumb question but I'm going to ask it anyway. I wonder why
halo is not available any more. From what I've seen, it's very good. Can't
it just be added back into the new version of PoV? There are so many things
I want to do that don't seem to work with media. Something like the fireball
I've seen posted...

Because the media concept is more universal, it replaces both atmosphere
and halo. Some other changes went together with it like the interior
structure and moving of things like ior from finish to interior.

It probably could, but AFAIK it was quite deeply nested with other things
so it would be a lot of work to get it running again, furthermore some
things could interfere with the media code.
Also note it was taken out of Povray for good reasons (see above) and
therefore will probably not be added to official povray again.

They probably could be done with media too, but without doubt some things
got much more complicated.

I don't know what fireball you mean, but here's a media-fireball:
sphere{0,1 pigment{rgbt 1}interior{media{emission<5,2,1>*4 density{spherical
scale.5 turbulence.5}density{granite}}}hollow}camera{location-z*2}
cu!

also, there is now the glow keyword in megapov. maybe glows are what
you need.

Did you read the documentation? It explains why.

The fireball I was thinking of was posted as 'Goodness gracious, great balls
of fire!' by Jonathan hunt. I'll try doing it with glows, I think that might
work.

It doesn't really give any reason. It just seemed not logical to take out
something that worked quite well and replace it with something that has a
lot more feature but can't do the same thing. I haven't seen any 3.1g update
of Jonathan's 'great balls of fire' for instance.
So I just assumed it should be easier to have them both.

See the section "Why are Interior and Media Necessary?"

It's true that in 3.1 the (only) sampling algorithm leaves a bit to be
desired. However, new sampling algorithms will be added to the new version
of povray, so this problem should be fixed by then (if you are impatient,
use MegaPov).
After that, I don't see any problem recreating all the same effects as
with halo. Granted, you may not get pixel-by-pixel identical results, but
if you tweak a bit you'll surely get results that are very close to the
halo effects.
With media you'll get more freedom as well.
