+BIND 9.20.13
+------------
+
+New Features
+~~~~~~~~~~~~
+
+- Add manual mode configuration option to dnsec-policy. ``1e435b107f``
+
+ Add a new option ``manual-mode`` to :any:`dnssec-policy`. The intended
+ use is that if it is enabled, it will not automatically move to the
+ next state transition, but instead the transition is logged. Only
+ after manual confirmation with ``rndc dnssec -step`` the transition is
+ made. :gl:`#4606` :gl:`!10880`
+
+- Add a new 'servfail-until-ready' configuration option for RPZ.
+ ``925af17d21``
+
+ By default, when :iscman:`named` is started it may start answering to
+ queries before the response policy zones are completely loaded and
+ processed. This new feature gives an option to the users to tell
+ :iscman:`named` that incoming requests should result in SERVFAIL
+ answer until all the response policy zones are processed and ready.
+ Note that if one or more response policy zones fail to load,
+ :iscman:`named` starts responding to queries according to those zones
+ that did load.
+
+ Note, that enabling this option has no effect when a DNS Response
+ Policy Service (DNSRPS) interface is used. :gl:`#5222` :gl:`!10889`
+
+- Support for parsing HHIT and BRID records has been added.
+ ``1f051af24d``
+
+ :gl:`#5444` :gl:`!10932`
+
+Removed Features
+~~~~~~~~~~~~~~~~
+
+- Deprecate the "tkey-gssapi-credential" statement. ``b239a70cac``
+
+ The :any:`tkey-gssapi-keytab` statement allows GSS-TSIG to be set up
+ in a simpler and more reliable way than using the
+ :any:`tkey-gssapi-credential` statement and setting environment
+ variables (e.g. ``KRB5_KTNAME``). Therefore, the
+ :any:`tkey-gssapi-credential` statement has been deprecated;
+ :any:`tkey-gssapi-keytab` should be used instead.
+
+ For configurations currently using a combination of both
+ :any:`tkey-gssapi-keytab` *and* :any:`tkey-gssapi-credential`, the
+ latter should be dropped and the keytab pointed to by
+ :any:`tkey-gssapi-keytab` should now only contain the credential
+ previously specified by :any:`tkey-gssapi-credential`. :gl:`#4204`
+ :gl:`!10924`
+
+- Obsolete the "tkey-domain" statement. ``9352ae65d7``
+
+ Mark the ``tkey-domain`` statement as obsolete, since it has not had
+ any effect on server behavior since support for TKEY Mode 2
+ (Diffie-Hellman) was removed (in BIND 9.20.0). :gl:`#4204`
+ :gl:`!10926`
+
+Feature Changes
+~~~~~~~~~~~~~~~
+
+- Update clang-format style with options added in newer versions.
+ ``0c2c477c31``
+
+ Add and apply InsertBraces statement to add missing curly braces
+ around one-line statements and use
+ ControlStatementsExceptControlMacros for SpaceBeforeParens to remove
+ space between foreach macro and the brace, e.g. `FOREACH (x) {`
+ becomes `FOREACH(x) {`. :gl:`!10864`
+
+Bug Fixes
+~~~~~~~~~
+
+- Ensure file descriptors 0-2 are in use. ``35dee6eb90``
+
+ libuv expect file descriptors <= STDERR_FILENO are in use. otherwise,
+ it may abort when closing a file descriptor it opened. :gl:`#5226`
+ :gl:`!10908`
+
+- Prevent spurious SERVFAILs for certain 0-TTL resource records.
+ ``6b266b222c``
+
+ Under certain circumstances, BIND 9 can return SERVFAIL when updating
+ existing entries in the cache with new NS, A, AAAA, or DS records with
+ 0-TTL. :gl:`#5294` :gl:`!10898`
+
+- Use DNS_RDATACOMMON_INIT to hide branch differences. ``a64df9729b``
+
+ Initialization of the common members of rdata type structures varies
+ across branches. Standardize it by using the `DNS_RDATACOMMON_INIT`
+ macro for all types, so that new types are more likely to use it, and
+ hence backport more cleanly. :gl:`#5467` :gl:`!10834`
+
+- RPZ canonical warning displays zone entry incorrectly. ``d833676515``
+
+ When an IPv6 rpz prefix entry is entered incorrectly the log message
+ was just displaying the prefix rather than the full entry. This has
+ been corrected. :gl:`#5491` :gl:`!10930`
+
+- Fix a catalog zone issue when having an unset 'default-primaries'
+ configuration clause. ``293e75af28``
+
+ A catalog zone with an unset ``default-primaries`` clause could cause
+ an unexpected termination of the :iscman:`named` process after two
+ reloading or reconfiguration commands. This has been fixed.
+ :gl:`#5494` :gl:`!10905`
+
+- Add and use __attribute__((nonnull)) in dnssec-signzone.c.
+ ``a8eed36d3e``
+
+ Clang 20 was spuriously warning about the possibility of passing a
+ NULL file pointer to `fprintf()`, which uses the 'nonnull' attribute.
+ To silence the warning, the functions calling `fprintf()` have been
+ marked with the same attribute to assure that NULL can't be passed to
+ them in the first place.
+
+ Close #5487 :gl:`!10913`
+
+- RPZ 'servfail-until-ready': skip updating SERVFAIL cache.
+ ``af2fb26325``
+
+ In order to not pollute the SERVFAIL cache with the configured
+ SERVFAIL answers while RPZ is loading, set the NS_CLIENTATTR_NOSETFC
+ attribute for the client. :gl:`!10940`
+
