This is the source portion of BIND version 8. Its companions are "doc" and
"contrib" so you are probably not missing anything.
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.
Note that BIND 8 is in "end-of-life", having been replaced by BIND 9. See
http://www.isc.org/ for more details.
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.
Fixes long-standing protocol incompatibility in DNSSEC support.
Avoids fwd'ing to root name servers if response will be rejected.
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.

To Support the Effort
Note that BIND is supported by the Internet Software Consortium, and
although it is free for use and redistribution and incorporation into
vendor products and export and anything else you can think of, it
costs money to produce. That money comes from ISPs, hardware and
software vendors, companies who make extensive use of the software,
and generally kind hearted folk such as yourself.
The Internet Software Consortium has also commissioned a DHCP server
implementation, has taken over official support/release of the INN
system, and has supported the Kerberos Version 5 effort at MIT. You
can learn more about the ISC's goals and accomplishments from the web
page at <URL:http://www.isc.org/>.
