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

  :gl:`#608`

Removed Features
~~~~~~~~~~~~~~~~

- None.

- Configuring control channel to use Unix Domain Socket has an fatal error since

  non-functional since BIND 9.18
