Feature Changes
~~~~~~~~~~~~~~~
-- In order to reduce unnecessary memory consumption in the cache,
- NXDOMAIN records are no longer retained past the normal negative
- cache TTL, even if ``stale-cache-enable`` is set to ``yes``.
- :gl:`#3386`.
-
-- The option :any:`auto-dnssec` is deprecated and will be removed in 9.19.
- Please migrate to :any:`dnssec-policy`. :gl:`#3667`
-
-- Deprecate setting the operating system limit (``coresize``, ``datasize``,
- ``files`` and ``stacksize``) from ``named.conf``. These options should be set
- from the operating system (``ulimit``) or from the process supervisor
+- To reduce unnecessary memory consumption in the cache, NXDOMAIN
+ records are no longer retained past the normal negative cache TTL,
+ even if :any:`stale-cache-enable` is set to ``yes``. :gl:`#3386`
+
+- The :any:`auto-dnssec` option has been deprecated and will be removed
+ in a future BIND 9.19.x release. Please migrate to
+ :any:`dnssec-policy`. :gl:`#3667`
+
+- The :any:`coresize`, :any:`datasize`, :any:`files`, and
+ :any:`stacksize` options have been deprecated. The limits these
+ options set should be enforced externally, either by manual
+ configuration (e.g. using ``ulimit``) or via the process supervisor
(e.g. ``systemd``). :gl:`#3676`
-- Deprecate setting alternate local addresses for inbound zone transfers
- (:any:`alt-transfer-source`, :any:`alt-transfer-source-v6`,
- :any:`use-alt-transfer-source`). :gl:`#3694`
+- Setting alternate local addresses for inbound zone transfers has been
+ deprecated. The relevant options (:any:`alt-transfer-source`,
+ :any:`alt-transfer-source-v6`, and :any:`use-alt-transfer-source`)
+ will be removed in a future BIND 9.19.x release. :gl:`#3694`
Bug Fixes
~~~~~~~~~
-- Increase the number of HTTP headers in the statistics channel from
- 10 to 100 to accomodate for some browsers that send more that 10
- headers by default. :gl:`#3670`
+- The number of HTTP headers allowed in requests sent to
+ :iscman:`named`'s statistics channel has been increased from 10 to
+ 100, to accommodate some browsers that send more than 10 headers
+ by default. :gl:`#3670`
+- TLS configuration for primary servers was not applied for zones that
+ were members of a catalog zone. This has been fixed. :gl:`#3638`
-- Copy TLS identifier when setting up primaries for catalog member
- zones. :gl:`#3638`
-
-- Fix an assertion failure in the statschannel caused by reading from the HTTP
- connection closed prematurely (connection error, shutdown). :gl:`#3693`
+- :iscman:`named` could crash due to an assertion failure when an HTTP
+ connection to the statistics channel was closed prematurely (due to a
+ connection error, shutdown, etc.). This has been fixed. :gl:`#3693`
- The ``zone <name>/<class>: final reference detached`` log message was
moved from the INFO log level to the DEBUG(1) log level to prevent the
:iscman:`named-checkzone` tool from superfluously logging this message
in non-debug mode. :gl:`#3707`
-- When a catalog zone is removed from the configuration, in some
- cases a dangling pointer could cause a :iscman:`named` process
- crash. This has been fixed. :gl:`#3683`
-
-- The ``named`` would wait for some outstanding recursing queries
- to finish before shutting down. This has been fixed. :gl:`#3183`
+- When a catalog zone was removed from the configuration, in some cases
+ a dangling pointer could cause the :iscman:`named` process to crash.
+ This has been fixed. :gl:`#3683`
-- When a zone is deleted from a server, an key management objects related to
- that zone would be kept in the memory and released only at the server
- shutdown. This could lead to constantly increasing memory usage for servers
- with a high zone churn. :gl:`#3727`
+- In certain cases, :iscman:`named` waited for the resolution of
+ outstanding recursive queries to finish before shutting down. This was
+ unintended and has been fixed. :gl:`#3183`
+- When a zone was deleted from a server, a key management object related
+ to that zone was inadvertently kept in memory and only released upon
+ shutdown. This could lead to constantly increasing memory use on
+ servers with a high rate of changes affecting the set of zones being
+ served. This has been fixed. :gl:`#3727`
