BIND 9.12.0 is a new feature release of BIND, still under development.
|
|
This document summarizes new features and functional changes that
|
|
have been introduced on this branch. With each development
|
|
release leading up to the final BIND 9.12.0 release, this document
|
|
will be updated with additional features added and bugs fixed.

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).
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
This new requirement will not affect anyone who is using BIND
|
|
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.
|
|
</para>
|
|
<para>
|
|
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 <link

Added the ability to specify the maximum number of records

permitted in a zone (<option>max-records #;</option>).

This provides a mechanism to block overly large zone

transfers, which is a potential risk with slave zones from
|
|
other parties, as described in CVE-2016-6170.
