   fixes.

Download

   The latest versions of BIND 9 software can always be found at
   http://www.isc.org/downloads/. There you will find additional
   information about each release, source code, and pre-compiled versions
   for Microsoft Windows operating systems.

License Change

   With the release of BIND 9.11.0, ISC changed to the open source license
   for BIND from the ISC license to the Mozilla Public License (MPL 2.0).

   The MPL-2.0 license requires that if you make changes to licensed
   software (e.g. BIND) and distribute them outside your organization,
   that you publish those changes under that same license. It does not
   require that you publish or disclose anything other than the changes
   you made to our software.

   This requirement will not affect anyone who is using BIND, with or
   without modifications, without redistributing it, nor anyone
   redistributing it without changes. Therefore, this change will be
   without consequence for most individuals and organizations who are
   using BIND.

   Those unsure whether or not the license change affects their use of
   BIND, or who wish to discuss how to comply with the license may contact
   ISC at https://www.isc.org/mission/contact/.

Security Fixes

     * A race condition could trigger an assertion failure when a large
       number of incoming packets were being rejected. This flaw is
       disclosed in CVE-2019-6471. [GL #942]

End of Life

   BIND 9.11 (Extended Support Version) will be supported until at least
   December, 2021. See
   https://www.isc.org/downloads/software-support-policy/ for details of
   ISC's software support policy.
