New Features
~~~~~~~~~~~~
- New configuration options, ``tcp-receive-buffer``, ``tcp-send-buffer``,
``udp-receive-buffer``, and ``udp-send-buffer``, have been added. These
options allows the operator to fine tune the receiving and sending
buffers in the operating system. On busy servers, increasing the value
of the receive buffers can prevent the server from dropping the packets
during short spikes, and decreasing the value would prevent the server to
became clogged up with queries that are too old and have already timeouted
on the receiving side. :gl:`#2313`

- Run zone dumping tasks on separate asynchronous thread pools. This change
makes zone dumping no longer block networking I/O. :gl:`#2732`
- Zone dumping tasks are now run on separate asynchronous thread pools.
This change prevents zone dumping from blocking network I/O.

- The interface handling code has been refactored to use fewer resources,
which should lead to less memory fragmentation and better startup
performance. :gl:`#2433`

Bug Fixes
~~~~~~~~~
- Fix a race condition in reading and writing key files for KASP zones in
multiple views. :gl:`#1875`
- A race condition could occur when reading and writing key files for
zones using KASP and configured in multiple views. This has been
fixed. :gl:`#1875`
- Check ``key-directory`` conflicts in ``named.conf`` for zones in multiple
views with different ``dnssec-policy``. Using the same ``key-directory`` for
such zones is not allowed. :gl:`#2463`
- Zones which are configured in multiple views, with different values
set for ``dnssec-policy`` and with identical values set for
``key-directory``, are now detected and treated as a configuration
error. :gl:`#2463`
- The calculation of the estimated IXFR transaction size by
`dns_journal_iter_init()` was invalid. This resulted in excessive
AXFR-style-IXFR responses. :gl:`#2685`
- The calculation of the estimated IXFR transaction size in
``dns_journal_iter_init()`` was invalid. This resulted in excessive
AXFR-style IXFR responses. :gl:`#2685`
- If a query was answered with stale data on a server with DNS64 enabled,
an assertion could occur if a non-stale answer arrived afterward. This
has been fixed. :gl:`#2731`
- If a query was answered with stale data on a server with DNS64
enabled, an assertion could occur if a non-stale answer arrived
afterward. This has been fixed. :gl:`#2731`
- Fixed an assertion failure that could occur if stale data was used
to answer a query, and then a prefetch was triggered after the query
was restarted (for example, to follow a CNAME). :gl:`#2733`
- Fixed an assertion failure that could occur if stale data was used to
answer a query, and then a prefetch was triggered after the query was
restarted (for example, to follow a CNAME). :gl:`#2733`
- Fix an error that would enable don't fragment socket option instead
of disabling it leading to errors when sending the oversized UDP
packets. [GL #2746]
- Fixed an error which caused the ``IP_DONTFRAG`` socket option to be
enabled instead of disabled, leading to errors when sending oversized
UDP packets. :gl:`#2746`
- Fixed a bug that caused the NSEC salt to be changed for KASP zones on
every startup. :gl:`#2725`
