BIND 8.4.6-REL is a security release of BIND 8.4.
It is possible to remotely trigger a overrun causing a
denial of service. If you are running BIND 8.4.4 or
BIND 8.4.5 you should upgrade.
Also:
1. Add ipv6 as a virtual category, since a key reason for the
BIND 8.4.x branch is IPv6 transport.
2. Download the PGP .asc files for the src and doc tarballs.
3. Add a new example file to PORTDOCS.
