If you look at a source diff between 8.2.2-P7 and 8.2.3, you might be
scared at some of the little things that were fixed. (There's a lot of
stuff added, too, as one might expect of a release and it is obviously
possible that there are problems introduced within those areas too.)

I can't comment about the big changes - I don't know the code well
enough - but there are a number of changes like this:

 -       if (SPRINTF((tmp, fmt, src[0], src[1], src[2], src[3])) > size) {
 +       if (SPRINTF((tmp, fmt, src[0], src[1], src[2], src[3])) >= size) {

and

 -               if (size < sizeof "255.")
 +               if (size <= sizeof "255.")

that make me willing to upgrade (presupposing they went the right way!)

My favourite inconsequential but useful change, which someone else in
this thread referred to, has to be:

 -                       "No default TTL set using SOA minimum instead");
 +               "No default TTL ($TTL <value>) set, using SOA minimum instead");

James.
