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]
4594. [func] dnssec-keygen no longer uses RSASHA1 by default;
the signing algorithm must be specified on
the command line with the "-a" option. Signing
scripts that rely on the existing default behavior
will break; use "dnssec-keygen -a RSASHA1" to
repair them. (The goal of this change is to make
it easier to find scripts using RSASHA1 so they
can be changed in the event of that algorithm
being deprecated in the future.) [RT #44755]
4674. [func] "dig +sigchase", and related options "+topdown" and
"+trusted-keys", have been removed. Use "delv" for
queries with DNSSEC validation. [RT #42793]
4669. [func] Iterative query logic in resolver.c has been
refactored into smaller functions and commented,
for improved readability, maintainability and
testability. [RT #45362]
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]
4637. [func] "nsec3hash -r" option ("rdata order") takes arguments
in the same order as they appear in NSEC3 or
NSEC3PARAM records, so that NSEC3 parameters can
be cut and pasted from an existing record. Thanks
to Tony Finch for the contribution. [RT #45183]
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]
4610. [func] The "new-zones-directory" option specifies the
location of NZF or NZD files for storing
configuration of zones added by "rndc addzone".
Thanks to Petr Menšík. [RT #44853]
4579. [func] Logging channels and dnstap output files can now
be configured with a "suffix" option, set to
either "increment" or "timestamp", indicating
whether to use incrementing numbers or timestamps
as the file suffix when rolling over a log file.
[RT #42838]
4572. [func] The "dnstap-output" option can now take "size" and
"versions" parameters to indicate the maximum size
a dnstap log file can grow before rolling to a new
file, and how many old files to retain. [RT #44502]
4549. [func] Added support for the EDNS TCP Keepalive option
(RFC 7828). [RT #42126]
4548. [func] Added support for the EDNS Padding option (RFC 7830).
[RT #42094]
4518. [func] The "print-time" option in the logging configuration
can now take arguments "local", "iso8601" or
"iso8601-utc" to indicate the format in which the
date and time should be logged. For backward
compatibility, "yes" is a synonym for "local".
[RT #42585]
4471. [cleanup] Render client/query logging format consistent for
ease of log file parsing. (Note that this affects
"querylog" format: there is now an additional field
indicating the client object address.) [RT #43238]
no-auth and no-auth-recursive which suppress
adding the NS records to the authority section
as well as the associated address records for the
nameservers. [RT #42005]
to provide feedback to the trust-anchor administrators
about how key rollovers are progressing as per
draft-ietf-dnsop-edns-key-tag-02. This can be
disabled using 'trust-anchor-telemetry no;'.
[RT #40583]
4421. [func] When built with LMDB (Lightning Memory-mapped
Database), named will now use a database to store
the configuration for zones added by "rndc addzone"
instead of using a flat NZF file. This improves
performance of "rndc delzone" and "rndc modzone"
significantly. Existing NZF files will
automatically by converted to NZD databases.
To view the contents of an NZD or to roll back to
NZF format, use "named-nzd2nzf". To disable
this feature, use "configure --without-lmdb".
[RT #39837]
4411. [func] "rndc dnstap -roll" automatically rolls the
dnstap output file; the previous version is
saved with ".0" suffix, and earlier versions
with ".1" and so on. An optional numeric argument
indicates how many prior files to save. [RT #42830]
added better text to describe the license change
added information about the following changes to notes.xml
+4396. [func] dnssec-keymgr now takes a '-r randomfile' option.
+ [RT #42455]
+4392. [func] Collect statistics for RSSAC02v3 traffic-volume,
+ traffic-sizes and rcode-volume reporting. [RT #41475]
+4388. [func] Support for master entries with TSIG keys in catalog
+ zones. [RT #42577]
+4385. [func] Add support for allow-query and allow-transfer ACLs
+ to catalog zones. [RT #42578]
provisioning secondary servers in which a list of
zones to be served is stored in a DNS zone and can
be propagated to slaves via AXFR/IXFR. [RT #41581]
4375. [func] Add support for automatic reallocation of isc_buffer
to isc_buffer_put* functions. [RT #42394]
