This 20document summarizes significant changes since the last production 21release on that branch. Please see the CHANGES file for a more detailed 22list of changes and bug fixes. 23 24Note on Version Numbering 25------------------------- 26 27As of BIND 9.13/9.14, BIND has adopted the "odd-unstable/even-stable" 28release numbering convention. BIND 9.16 contains new features that were 29added during the BIND 9.15 development process. Henceforth, the 9.16 30branch will be limited to bug fixes, and new feature development will 31proceed in the unstable 9.17 branch. 32 33Supported Platforms 34------------------- 35 36To build on Unix-like systems, BIND requires support for POSIX.1c 37threads (IEEE Std 1003.1c-1995), the Advanced Sockets API for IPv6 38(:rfc:`3542`), and standard atomic operations provided by the C 39compiler. 40 41The libuv asynchronous I/O library and the OpenSSL cryptography library 42must be available for the target platform. A PKCS#11 provider can be 43used instead of OpenSSL for Public Key cryptography (i.e., DNSSEC 44signing and validation), but OpenSSL is still required for general 45cryptography operations such as hashing and random number generation. 46 47More information can be found in the ``PLATFORMS.md`` file that is 48included in the source distribution of BIND 9. If your compiler and 49system libraries provide the above features, BIND 9 should compile and 50run. If that is not the case, the BIND development team will generally 51accept patches that add support for systems that are still supported by 52their respective vendors. 53 54Download 55-------- 56 57The latest versions of BIND 9 software can always be found at 58https://www.isc.org/download/. There you will find additional 59information about each release, source code, and pre-compiled versions 60for Microsoft Windows operating systems. 61 62.. include:: ../notes/notes-9.16.20.rst 63.. include:: ../notes/notes-9.16.19.rst 64.. include:: ../notes/notes-9.16.18.rst 65.. include:: ../notes/notes-9.16.17.rst 66.. include:: ../notes/notes-9.16.16.rst 67.. include:: ../notes/notes-9.16.15.rst 68.. include:: ../notes/notes-9.16.14.rst 69.. include:: ../notes/notes-9.16.13.rst 70.. include:: ../notes/notes-9.16.12.rst 71.. include:: ../notes/notes-9.16.11.rst 72.. include:: ../notes/notes-9.16.10.rst 73.. include:: ../notes/notes-9.16.9.rst 74.. include:: ../notes/notes-9.16.8.rst 75.. include:: ../notes/notes-9.16.7.rst 76.. include:: ../notes/notes-9.16.6.rst 77.. include:: ../notes/notes-9.16.5.rst 78.. include:: ../notes/notes-9.16.4.rst 79.. include:: ../notes/notes-9.16.3.rst 80.. include:: ../notes/notes-9.16.2.rst 81.. include:: ../notes/notes-9.16.1.rst 82.. include:: ../notes/notes-9.16.0.rst 83 84.. _relnotes_license: 85 86License 87------- 88 89BIND 9 is open source software licensed under the terms of the Mozilla 90Public License, version 2.0 (see the ``LICENSE`` file for the full 91text). 92 93The license requires that if you make changes to BIND and distribute 94them outside your organization, those changes must be published under 95the same license.
