Notes for BIND 9.19.24
----------------------

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

- None.

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

- A new option :any:`signatures-jitter` is added to :any:`dnssec-policy` to
  spread out signature expiration times over a period of time. :gl:`#4554`

- A new DNSSEC tool :iscman:`dnssec-ksr` is added to create Key Signing Request
  (KSR) and Signed Key Response (SKR) files. :gl:`#1128`

- Queries and responses now emit distinct dnstap entries for DoT and DoH.
  :any:`dnstap-read` understands DoH and DoT entries. :gl:`#4523`

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

- The ``named`` command line option ``-U <n>``, which specified the number of UDP dispatches,
  has been removed. Using it now prints a warning.  :gl:`#1879`

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

- Querying the statistics channel no longer blocks the DNS communication
  on the networking event loop. :gl:`#4680`

- DNSSEC signatures that are not valid because the current time falls outside
  the signature inception and expiration dates no longer count towards maximum
  validation and maximum validation failures limits. :gl:`#4586`

- Multiple RNDC messages will be processed when sent in a single TCP
  message.

  ISC would like to thank Dominik Thalhammer for reporting the issue
  and preparing the initial patch. :gl:`#4416`

- :iscman:`dnssec-keygen` now allows the options ``-k`` and ``-f`` to be
  used together. This allows creating keys for a given :any:`dnssec-policy`
  that match only the KSK (``-fK``) or ZSK (``-fZ``) role.

Bug Fixes
~~~~~~~~~

- None.
