Well, judging from the mailling list traffic, it seems they stopped
handing out dns_update (you can get it from the website) and started
distributing this:

# From: Jason Gunthorpe <jgg@deltatee.com>
# To: samba@packages.debian.org
# Subject: Nifty samba script
#
# Here is a really nifty script I just wrote for samba, it takes the
# wins database in /var/samba/wins and writes out two dns files for it.
# In this way network wide wins clients can get into the dns for use by
# unix machines.
#
# Perhaps this could be included in  /usr/doc/examples or somesuch.

BEGIN {
  FS=3D"#|\"";
FORWARD=3D"/tmp/wins.hosts"
REVERSE=3D"/tmp/wins.rev"
DOMAIN=3D"caresswm.org"
}
$3 =3D=3D "00" {
  split($4,a," " );
  split(a[2],b,".");
  while (sub(" ","-",$2));
  $2=3Dtolower($2);
  if (b[1] =3D=3D "255")
    next;
  if (length($2) >=3D 8)
    print $2"\ta\t"a[2] > FORWARD
  else
    print $2"\t\ta\t"a[2] > FORWARD
  print b[4]"."b[3]"\t\tptr\t"$2"."DOMAIN"." > REVERSE
}
END {
  system("echo killall -HUP named");
}
