Notes for BIND 9.16.25
----------------------
Feature Changes
~~~~~~~~~~~~~~~
- Overall memory use by ``named`` has been optimized and reduced,
especially on systems with many CPU cores. The default memory
allocator has been switched from ``internal`` to ``external``. A new
command-line option ``-M internal`` allows ``named`` to be started
with the old internal memory allocator. :gl:`#2398`
Bug Fixes
~~~~~~~~~
- On FreeBSD, TCP connections leaked a small amount of heap memory,
leading to an eventual out-of-memory problem. This has been fixed.
:gl:`#3051`
- If signatures created by the ZSK were expired and the ZSK private key
was offline, the signatures were not replaced. This behavior has been
amended to replace the expired signatures with new signatures created
using the KSK. :gl:`#3049`
- Under certain circumstances, the signed version of an inline-signed
zone could be dumped to disk without the serial number of the unsigned
version of the zone. This prevented resynchronization of the zone
contents after ``named`` restarted, if the unsigned zone file was
modified while ``named`` was not running. This has been fixed.
:gl:`#3071`
Known Issues
~~~~~~~~~~~~
- There are no new known issues with this release. See :ref:`above
<relnotes_known_issues>` for a list of all known issues affecting this
BIND 9 branch.
