Notes for BIND 9.18.14
----------------------
Removed Features
~~~~~~~~~~~~~~~~
- Zone type ``delegation-only``, and the ``delegation-only`` and
``root-delegation-only`` statements, have been deprecated.
A warning is now logged when they are used.
These statements 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 statements are no longer needed. :gl:`#3953`
Bug Fixes
~~~~~~~~~
- Several bugs which could cause :iscman:`named` to crash during catalog
zone processing have been fixed. :gl:`#3955` :gl:`#3968` :gl:`#3997`
- Previously, downloading large zones over TLS (XoT) from a primary
could hang the transfer on the secondary, especially when the
connection was unstable. This has been fixed. :gl:`#3867`
- Performance of DNSSEC validation in zones with many DNSKEY records has
been improved. :gl:`#3981`
Known Issues
~~~~~~~~~~~~
- There are no new known issues with this release. See :ref:`above
<relnotes_known_issues>` for a list of all known issues affecting this
BIND 9 branch.
