New Features
~~~~~~~~~~~~
- Support for parsing the DSYNC record has been added.
- Support for parsing DSYNC records has been added.
:gl:`#5440`
These records are used for discovering the receiver endpoint for DNS
notification messages. For more information, see

- Reword the 'shut down hung fetch while resolving' message.

The log message ``shut down hung fetch while resolving`` may be
confusing, because no detection of hung fetches actually takes place.
Instead, the timer on the fetch context expires and the resolver
gives up.
Change the log message to actually say that instead of the original
cryptic message about hung fetch. :gl:`#3148`
- Use native shared library extension.
Use the native shared library extension when build loadable libaries.
For most platforms this is ".so" but for Darwin it is ".dylib".
:gl:`#5375`
The log message has been changed to actually indicate that, instead of the
original cryptic message about hung fetch. :gl:`#3148`
- Plugin extension in plugin path is now optional.
Plugin configuration no longer requires the library file extension, so
it is now possible to invoke a plugin using the syntax `plugin query
"library"` instead of `plugin query "libary.so"`. :gl:`#5377`

Bug Fixes

- Stale RRsets in a CNAME chain were not always refreshed.
With serve-stale enabled, a CNAME chain that contains a stale RRset,
the refresh query doesn't always properly refresh the stale RRsets.
Previously, with serve-stale enabled and a CNAME chain that contained a stale RRset,
the refresh query didn't always properly refresh the stale RRsets.
This has been fixed. :gl:`#5243`
- Add RPZ extended DNS error for zones with a CNAME override policy
configured.
When the zone is configured with a CNAME override policy, or the
response policy zone contains a wildcard CNAME, the extended DNS error
Previously, when the zone was configured with a CNAME override policy, or the
response policy zone contained a wildcard CNAME, the extended DNS error
code was not added. This has been fixed. :gl:`#5342`
- Fix cross builds.
Cross-compilation did not work even when the ``-Ddoc=disabled`` build
option was passed to Meson due to the build targets used for
generating documentation depending on a non-native executable. This
option was passed to Meson, because the build targets used for
generating documentation depended on a non-native executable. This

- Fix named-makejournal man page installation.
- Fix :iscman:`named-makejournal` man page installation.
The man page for :iscman:`named-makejournal` was erroneously not
installed when building from a source tarball. This has been fixed.

- Clean enough memory when adding new ADB names/entries under memory
pressure.
The ADB memory cleaning is opportunistic even when we are under memory
pressure (in the overmem condition). Split the opportunistic LRU
cleaning and overmem cleaning and make the overmem cleaning always
cleanup double of the newly allocated adbname/adbentry to ensure we
never allocate more memory than the assigned limit.
The ADB memory cleaning is opportunistic even when BIND is under memory
pressure (in the overmem condition). :iscman:`named` now ensures that the assigned memory
limit is not exceeded by releasing twice the amount of memory
allocated for each new ADB name/entry when under memory pressure.

- Prevent spurious validation failures.
Under rare circumstances, validation could fail if multiple clients
simultaneously iterated the same set of signatures.
