Notes for BIND 9.19.12
----------------------

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

- None.

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

- BIND now depends on ``liburcu``, Userspace RCU, for lock-free data
  structures. :gl:`#3934`

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

- The TKEY Mode 2 (Diffie-Hellman Exchanged Keying Mode) has been removed and
  using TKEY Mode 2 is now a fatal error.  Users are advised to switch to TKEY
  Mode 3 (GSS-API). :gl:`#3905`

- Zone type ``delegation-only``, and the ``delegation-only`` and
  ``root-delegation-only`` options, have been deprecated; a warning will
  be logged when they are used.

  These options were created to address the SiteFinder controversy, in
  which certain top-level domains redirected misspelled queries to other
  sites instead of returning NXDOMAIN responses. Since top-level domains are
  now DNSSEC signed, and DNSSEC validation is active by default, the
  options are no longer needed. :gl:`#3953`

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