BIND 9.17 is an unstable development release of BIND. This document summarizes new features and functional changes that have been introduced on this branch. With each development release leading up to the stable BIND 9.18 release, this document will be updated with additional features added and bugs fixed.
Please see the file CHANGES for a more
detailed list of changes and bug fixes.
To build on UNIX-like systems, BIND 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.
The libuv asynchronous I/O library and the
OpenSSL cryptography library must be available for the target
platform. A PKCS#11 provider can be used instead of OpenSSL 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.
More information can be found in the PLATFORMS.md
file that is included in the source distribution of BIND 9. If your
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.
The latest versions of BIND 9 software can always be found at https://www.isc.org/download/. There you will find additional information about each release, source code, and pre-compiled versions for Microsoft Windows operating systems.
BIND 9 is open source software licensed under the terms of the Mozilla
Public License, version 2.0 (see the LICENSE
file for the full text).
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.
Those wishing to discuss license compliance may contact ISC at https://www.isc.org/contact/.
BIND 9.17 is an unstable development branch. When its development is complete, it will be renamed to BIND 9.18, which will be a stable branch.
The end of life date for BIND 9.18 has not yet been determined. For those needing long term support, the current Extended Support Version (ESV) is BIND 9.11, which will be supported until at least December 2021.
