Notes for BIND 9.17.4
---------------------

Security Fixes
~~~~~~~~~~~~~~

- None.

Known Issues
~~~~~~~~~~~~

- None.

New Features
~~~~~~~~~~~~

- ``rndc`` has been updated to use the new BIND network manager API.
  This change had the side effect of altering the TCP timeout for RNDC
  connections from 60 seconds to the ``tcp-idle-timeout`` value, which
  defaults to 30 seconds. Also, because the network manager currently
  has no support for UNIX-domain sockets, those cannot now be used
  with ``rndc``. This will be addressed in a future release, either by
  restoring UNIX-domain socket support or by formally declaring them
  to be obsolete in the control channel. [GL #1759]

Feature Changes
~~~~~~~~~~~~~~~

- None.

Bug Fixes
~~~~~~~~~

- Addressed an error in recursive clients stats reporting.
  There were occasions when an incoming query could trigger a prefetch for
  some eligible rrset, and if the prefetch code were executed before recursion,
  no increment in recursive clients stats would take place. Conversely,
  when processing the answers, if the recursion code were executed before the
  prefetch, the same counter would be decremented without a matching increment.
  [GL #1719]

- The introduction of KASP support broke whether the second field
  of sig-validity-interval was treated as days or hours. (Thanks to
  Tony Finch.) [GL !3735]
