|
- When a secondary server receives a large incremental zone
|
|
transfer (IXFR), it can have a negative impact on query
|
|
performance while the incremental changes are applied to
|
|
the zone. To address this, ``named`` can now
|
|
limit the size of IXFR responses it sends in response to zone
|
|
transfer requests. If an IXFR response would be larger than an
|
|
AXFR of the entire zone, it will send an AXFR resonse instead.
|
|
|
|
This behavior is controlled by the ``max-ixfr-ratio``
|
|
option - a percentage value representing the ratio of IXFR size
|
|
to the size of a full zone transfer. This value cannot exceed
|
|
100%, which is also the default. [GL #1515]

Feature Changes
|
|
~~~~~~~~~~~~~~~
|
|
|
|
- The SONAMEs for BIND 9 libraries now include the current BIND 9
|
|
version number, in an effort to tightly couple internal libraries with
|
|
a specific release. This change makes the BIND 9 release process both
|
|
simpler and more consistent while also unequivocally preventing BIND 9
|
|
binaries from silently loading wrong versions of shared libraries (or
|
|
multiple versions of the same shared library) at startup. [GL #2387]
|
|
|
|
- The default value of ``max-stale-ttl`` has been changed from 12 hours to 1
|
|
day and the default value of ``stale-answer-ttl`` has been changed from 1
|
|
second to 30 seconds, following RFC 8767 recommendations. [GL #2248]
|
|
|
|
- As part of an ongoing effort to use RFC 8499 terminology,
|
|
``primaries`` can now be used as a synonym for ``masters`` in
|
|
``named.conf``. Similarly, ``notify primary-only`` can now be used as
|
|
a synonym for ``notify master-only``. The output of ``rndc
|
|
zonestatus`` now uses ``primary`` and ``secondary`` terminology.

Bug Fixes

|
- KASP incorrectly set signature validity to the value of the DNSKEY signature
|
|
validity. This is now fixed. [GL #2383]
