New Features ~~~~~~~~~~~~ - The statstics channel now includes information about incoming zone transfers currently in progress. :gl:`#3883` - The new :any:`resolver-use-dns64` option enables ``named`` to apply :any:`dns64` rules to IPv4 server addresses when sending recursive queries, so that resolution can be performed over a NAT64 connection. :gl:`#608` - Processing large incremental transfers (IXFR) can take a long time. Offload the processing to a separate work thread that doesn't block networking threads and keeps them free to process regular traffic. :gl:`#4367` Removed Features ~~~~~~~~~~~~~~~~ - Configuring control channel to use Unix Domain Socket has an fatal error since BIND 9.18. Completely remove the feature and make ``named-checkconf`` also report this as an error in the configuration. :gl:`#4311` The support for control channel over Unix Domain Sockets has been non-functional since BIND 9.18 - Support for specifying ``lock-file`` via configuration and via the :option:`named -X` command line option has been removed. An external process supervisor should be used instead. :gl:`#4391` Alternatively :program:`flock` can be used to achieve the same effect as the removed configuration/argument: flock -n -x
