This is the source portion of BIND version 8.  Its companions are "doc" and
"contrib" so you are probably not missing anything.

NOTE:
	BIND 8 is in "end-of-life", having been replaced by BIND 9.  See
	http://www.isc.org/ for more details.

See the CHANGES file for a detailed listing of all changes.  See the INSTALL
file for information on building and installing BIND.

See the SUPPORT file for information on obtaining commercial support for ISC
artifacts including BIND, INN, and DHCP.

To Support the Effort

	ISC provides BIND and other high quality reference implementations
	of core internet protocols, unencumbered and free of charge.  We
	are a nonprofit public benefit corporation, and we need support
	from the BIND user community in order to enhance our efforts.

	See http://www.isc.org/ to learn about the BIND Forum, specialized
	support and enhancement contracts, donations, and other ways to
	help (and other things we do).            -- sales@isc.org

BIND 8.4.6 Highlights
	Maintenance release.
	Security Fix: Buffer Overrun (q_usedns).

BIND 8.4.5 Highlights
	Maintenance release.
	nsupdate: The use of a blank line to cause a update request
	to be sent is deprecated.  Use "send" instead.

BIND 8.4.4 Highlights
	Maintenance release.

BIND 8.4.3 Highlights
	Maintenance release.

BIND 8.4.2 Highlights
	Maintenance release.
	Security Fix: Negative Cache Poison Fix.

BIND 8.4.1 Highlights
	Maintenance release.

BIND 8.4.0 Highlights
	IPv6 transport support for named, named-xfer and ndc.

BIND 8.3.4 Highlights
	Security Fix DoS and buffer overrun.

BIND 8.3.3 Highlights
	Security Fix libbind. All applications linked against libbind
	need to relinked.
	'rndc restart' now preserves named's arguements

BIND 8.3.2 Highlights
	dig, nslookup, host and nsupdate have improved IPv6 support.

BIND 8.3.1 Highlights
	Critical bug fix to prevent DNS storms. If you have BIND 8.3.0 you
	need to upgrade.

BIND 8.3.0 Highlights
	IPv6 transport support in resolver (from KAME).
	Opaque rdata support.
	EDNS0 support.
	Glue ordering to help non-ENDS0 aware clients (servers) cope with
	larger responses as a result of IPv6 by allowing A records to be added
	first to the additional section.  IPv6 capable clients are expected to
	use EDNS0 to allow larger responses to be sent.
	Bug Fixes, includes BIND 8.2.5 changes.

BIND 8.2.4 Highlights
	NSAP processing was not RFC 1706 compliant. NOTE: OLD MASTER FILES
	NEED TO BE CORRECTED AND CACHE FILES REMOVED.

	new port/cygwin contributed by s_c_biggs@bigfoot.com.
	new contrib/mdnkit (V1.3) from author.
	new contrib/adm from official ftp site.
	new contrib/host from author.
	new contrib/dnsp from author.
	fixed file descriptor leak in resolver.
	fixed a major memory leak in the processing of dynamic updates.
	numerous portability improvements.
	numerous bug fixes.

BIND 8.2.3 Highlights

	Improved support for Windows NT and Windows 2000.
	Host stats are no longer required to track the source of a record.
	IXFR improvements.
	Forwarders track and use RTT to select fastest.
	Unix domain sockets implementions that require the directory
	to be secure, are now secured.
	Many minor problems fixed.
	Linux DoS removed.

BIND 8.2.2 patchlevel 5 Highlights

	Bug in named-xfer (from patchlevel 4).
	Portability to IPv6 versions of FreeBSD, OpenBSD, NetBSD.
	Portability improvements (A/UX, AIX, IRIX, NetBSD, SCO, MPE/IX, NT).
	"also-notify" option could cause memory allocation errors.
	IXFR improvements (though client-side is still disabled).
	Contributed software upgraded (including TIS's "dns_signer").
	Several latent denial-of-service bugs fixed (from audits, not abuse).
	New "make noesw" top-level target for removing encumbered components.

BIND 8.2.2 Highlights

	Interoperability with MS-Win2K has been improved.                     
	Server-side IXFR is now known to work even under high load.                 
	Support for Windows/NT (thanks to BayNetworks).
	More fixes, especially to DNSSEC, TSIG, IXFR, and selective forwarding.
	More portability improvements and lint removal (A/UX 3.1.1, SCO 5.0).
	Better NOTIFY behaviour, especially with large update volume.
	Better UPDATE handling, including SRV RR support and RFC compliance.
	Fix for "ndc reload ZONENAME" (specific zone reload) problems.
	Fix for round robin when multiple CNAMEs are in use.
	New "min-roots" (MINROOTS) and "serial-queries" (MAXQSERIAL) options.
	Log files are no longer auto-rotated every time the server starts up.
	New "ndc reconfig" command only finds new/deleted zones, no stat()ing.
	New global options for "transfer-source" and "also-notify".
	$GENERATE now supports more record types, and options.

BIND 8.2.1 Highlights

	Bug fixes, especially to DNSSEC, TSIG, IXFR, and selective forwarding.
	Portability improvements and lint removal.
	Use best SOA rather than first-better when selecting an AXFR master.
	$TTL now accepts symbolic time values (such as "$TTL 1h30m").
	"ndc reload" now accepts a zone argument, for single-zone reloads.
	ndc is better behaved; is verbose or quiet when appropriate.
	event and error reporting improvements.

BIND 8.2 Highlights

	RFC 2308 (Negative Caching)
	RFC 2181 (DNS Clarifications)
	RFC 2065 (DNS Security)
	TSIG (Transaction SIGnatures)
	support for multiple virtual name servers
	NDC uses a "control channel" now (no more signals)
	"Split DNS" via zone type "forward".

	Many bug fixes
	Documentation improvements
	Performance enhancements

BIND 8.1.2 Highlights

	Security fixes for a number of problems including:

		An attacker could overwrite the stack if inverse query support
		was enabled.

		A number of denial of service attacks where malformed packets
		could cause the server to crash.

		The server was willing to answer queries on its forwarding
		sockets.

	Several memory leaks have been plugged.

	The server no longer panics if a periodic interface scan fails due
	to no file descriptors being available.

	Updates to a number of ports.  New ports for QNX, LynxOS, HP-UX 9.x,
	and HP MPE.

	"files unlimited" now works as expected on systems where setting
	an infinite rlim_max for RLIMIT_NOFILE works.

	Adding and deleting the same record in the same dynamic update no
	longer crashes the server.

	If a dynamic update fails, rollback is now done in LIFO order instead
	of FIFO order.

	Better behavior when priming of the root servers fails.

	purge_zone() didn't work correctly for the root zone, allowing
	old data to persist after loading the zone.

	Improved handling of oversized UDP packets.

	All hosts on the also-notify list are now notified.

	The meaning of the count returned by select() varies somewhat by
	operating system, and this could cause previous releases of the
	server to spin.

	Per-host statistics may be disabled by specifying 'host-statistics no'
	in named.conf.

	The maximum number of zones has been increased from 32768 to 65536.

	query-source may specify an address and port that the server is
	already listening on.  BIND 8.1.1 required that either the address
	or port be wild.  E.g., you can now say:

		listen-on port 53 { 10.0.0.1; };
		query-source address 10.0.0.1 port 53;

	The value of FD_SETSIZE to use may be specified.

	Experimental -u (set user id), -g (set group id), and -t (chroot)
	command line options.  See the INSTALL file for details.
