12Notes for BIND 9.18.14
13----------------------
14
15Removed Features
16~~~~~~~~~~~~~~~~
17
18- Zone type ``delegation-only``, and the ``delegation-only`` and
19  ``root-delegation-only`` statements, have been deprecated.
20  A warning is now logged when they are used.
21
22  These statements were created to address the SiteFinder controversy,
23  in which certain top-level domains redirected misspelled queries to
24  other sites instead of returning NXDOMAIN responses. Since top-level
25  domains are now DNSSEC-signed, and DNSSEC validation is active by
26  default, the statements are no longer needed. :gl:`#3953`
27
28Bug Fixes
29~~~~~~~~~
30
31- Several bugs which could cause :iscman:`named` to crash during catalog
32  zone processing have been fixed. :gl:`#3955` :gl:`#3968` :gl:`#3997`
33
34- Previously, downloading large zones over TLS (XoT) from a primary
35  could hang the transfer on the secondary, especially when the
36  connection was unstable. This has been fixed. :gl:`#3867`
37
38- Performance of DNSSEC validation in zones with many DNSKEY records has
39  been improved. :gl:`#3981`
