This document summarizes changes since the last production
release on the BIND 9.12 branch. Please see the
CHANGES for a further list of bug fixes
and other changes.
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.
update-policy rules that otherwise ignore the name field now require that it be set to "." to ensure that any type list present is properly interpreted. Previously, if the name field was omitted from the rule declaration but a type list was present, it wouldn't be interpreted as expected.
When answering authoritative queries, named does not return the target of a cross-zone CNAME between two locally served zones; this prevents accidental cache poisoning. This same restriction was incorrectly applied to recursive queries as well; this has been fixed. [RT #47078]
named could crash when acting as a slave for a catalog zone if zone contained a master definition without an IP address. [RT #45999]
BIND is open source software licenced under the terms of the Mozilla
Public License, version 2.0 (see the
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/mission/contact/.
The end-of-life date for BIND 9.12 has not yet been determined. However, it is not intended to be an Extended Support Version (ESV) branch; accordingly, support will end after the next stable branch (9.14) becomes available. Those needing a longer-lived branch are encouraged to use the current ESV, BIND 9.11, which will be supported until December 2021. See https://www.isc.org/downloads/software-support-policy/ for details of ISC's software support policy.
