BIND 9.14 is a stable branch of BIND.

This document summarizes significant changes since the last

production release on that branch.

As of BIND 9.13/9.14, BIND has adopted the "odd-unstable/even-stable"
|
|
release numbering convention. BIND 9.14 contains new features added
|
|
during the BIND 9.13 development process. Henceforth, the 9.14 branch
|
|
will be limited to bug fixes and new feature development will proceed
|
|
in the unstable 9.15 branch, and so forth.

<para>
|
|
Since 9.12, BIND has undergone substantial code refactoring and
|
|
cleanup, and some very old code has been removed that supported
|
|
obsolete operating systems and operating systems for which ISC is
|
|
no longer able to perform quality assurance testing. Specifically,
|
|
workarounds for UnixWare, BSD/OS, AIX, Tru64, SunOS, TruCluster
|
|
and IRIX have been removed.
|
|
</para>
|
|
<para>
|
|
On UNIX-like systems, BIND now requires support for POSIX.1c
|
|
threads (IEEE Std 1003.1c-1995), the Advanced Sockets API for
|
|
IPv6 (RFC 3542), and standard atomic operations provided by the
|
|
C compiler.
|
|
</para>
|
|
<para>
|
|
More information can be found in the <filename>PLATFORM.md</filename>
|
|
file that is included in the source distribution of BIND 9. If your
|
|
platform compiler and system libraries provide the above features,
|
|
BIND 9 should compile and run. If that isn't the case, the BIND
|
|
development team will generally accept patches that add support
|
|
for systems that are still supported by their respective vendors.
|
|
</para>
|
|
<para>
|
|
As of BIND 9.14, the BIND development team has also made cryptography
|
|
(i.e., TSIG and DNSSEC) an integral part of the DNS server. The
|
|
OpenSSL cryptography library must be available for the target
|
|
platform. A PKCS#11 provider can be used instead for Public Key
|
|
cryptography (i.e., DNSSEC signing and validation), but OpenSSL is
|
|
still required for general cryptography operations such as hashing
|
|
and random number generation.

This combination of settings was never intended to work,

but there was no check for it in the parser. This has been

corrected; a warning is now logged. (In BIND 9.15 and

higher this error will be fatal.) [GL #868]

BIND is open source software licenced under the terms of the Mozilla

The license requires that if you make changes to BIND and distribute
|
|
them outside your organization, those changes must be published under
|
|
the same license. It does not require that you publish or disclose
|
|
anything other than the changes you have made to our software. This
|
|
requirement does not affect anyone who is using BIND, with or without
|
|
modifications, without redistributing it, nor anyone redistributing
|
|
BIND without changes.
