4873. [doc] Grammars for named.conf included in the ARM are now
automatically generated by the configuration parser
itself. As a side effect of the work needed to
separate zone type grammars from each other, this
also makes checking of zone statements in
named-checkconf more correct and consistent.
[RT #36957]
4762. [func] "update-policy local" is now restricted to updates
from local addresses. (Previously, other addresses
were allowed so long as updates were signed by the
local session key.) [RT #45492]
4749. [func] The ISC DLV service has been shut down, and all
DLV records have been removed from dlv.isc.org.
- Removed references to ISC DLV in documentation
- Removed DLV key from bind.keys
- No longer use ISC DLV by default in delv
[RT #46155]
4724. [func] By default, BIND now uses the random number
functions provided by the crypto library (i.e.,
OpenSSL or a PKCS#11 provider) as a source of
randomness rather than /dev/random. This is
suitable for virtual machine environments
which have limited entropy pools and lack
hardware random number generators.
This can be overridden by specifying another
entropy source via the "random-device" option
in named.conf, or via the -r command line option;
however, for functions requiring full cryptographic
strength, such as DNSSEC key generation, this
cannot be overridden. In particular, the -r
command line option no longer has any effect on
dnssec-keygen.
This can be disabled by building with
"configure --disable-crypto-rand".

Stage 2 - synthesis of records from wildcard data.
If the dns64 or filter-aaaa* is configured then the
involved lookups are currently excluded. [RT #40138]
4721. [func] 'dnssec-signzone -x' and 'dnssec-dnskey-kskonly'
options now apply to CDNSKEY and DS records as well
as DNSKEY. Thanks to Tony Finch. [RT #45689]
4713. [func] Added support for the DNS Response Policy Service
(DNSRPS) API, which allows named to use an external
response policy daemon when built with
"configure --enable-dnsrps". Thanks to Vernon
Schryver and Farsight Security. [RT #43376]
4708. [cleanup] Legacy Windows builds (i.e. for XP and earlier)
are no longer supported. [RT #45186]
4707. [func] The lightweight resolver daemon and library (lwresd
and liblwres) have been removed. [RT #45186]
4706. [func] Code implementing name server query processing has
been moved from bin/named to a new library "libns".
Functions remaining in bin/named are now prefixed
with "named_" rather than "ns_". This will make it
easier to write unit tests for name server code, or
link name server functionality into new tools.
[RT #45186]
allows named to provide stale cached answers when
the authoritative server is under attack.
See max-stale-ttl, stale-answer-enable,
stale-answer-ttl. [RT #44790]
4664. [func] Add a "glue-cache" option to enable or disable the
glue cache. The default is "no" to reduce memory
usage, but enabling this option will improve
performance in delegation-heavy zones. [RT #45125]
4613. [func] By default, the maximum size of a zone journal file
is now twice the size of the zone's contents (there
is little benefit to a journal larger than this).
This can be overridden by setting "max-journal-size"
to "unlimited" or to an explicit value up to 2G.
Thanks to Tony Finch. [RT #38324]
