 			[GL #622]
 5317.	[func]		A new asynchronous network communications system

 5312.	[bug]		Do not flush the cache for `rndc validation status`.

 5310.	[bug]		TCP failures were affecting EDNS statistics. [GL #1059]
 5309.	[placeholder]
 5308.	[bug]		Don't log DNS_R_UNCHANGED from sync_secure_journal()
 			at ERROR level in receive_secure_serial(). [GL #1288]

 			queries. (CVE-2019-6477) [GL #1264]
 5305.	[bug]		NSEC Aggressive Cache ("synth-from-dnssec") has been
 			disabled by default because it was found to have
 			a significant performance impact on the recursive
 			service. [GL #1265]
 5304.	[bug]		"dnskey-sig-validity 0;" was not being accepted.
 			[GL #876]
 5303.	[placeholder]
 5302.	[bug]		Fix checking that "dnstap-output" is defined when
 			"dnstap" is specified in a view. [GL #1281]
 5301.	[bug]		Detect partial prefixes / incomplete IPv4 address in
 			acls. [GL #1143]
 5300.	[bug]		dig/mdig/delv: Add a colon after EDNS option names,
 			even when the option is empty, to improve
 			readability and allow correct parsing of YAML
 			output. [GL #1226]
 	--- 9.15.5 released ---
 5299.	[security]	A flaw in DNSSEC verification when transferring
 			mirror zones could allow data to be incorrectly
 			marked valid. (CVE-2019-6475) [GL #1252]
 5298.	[security]	Named could assert if a forwarder returned a
 			referral, rather than resolving the query, when QNAME
 			minimization was enabled. (CVE-2019-6476) [GL #1051]
 5297.	[bug]		Check whether a previous QNAME minimization fetch
 			is still running before starting a new one; return
 			SERVFAIL and log an error if so. [GL #1191]
 5296.	[placeholder]
 5295.	[cleanup]	Split dns_name_copy() calls into dns_name_copy() and
 			dns_name_copynf() for those calls that can potentially
 			fail and those that should not fail respectively.
 			[GL !2265]
 5294.	[func]		Fallback to ACE name on output in locale, which does not
 			support converting it to unicode.  [GL #846]
 5293.	[bug]		On Windows, named crashed upon any attempt to fetch XML
 			statistics from it. [GL #1245]
 5292.	[bug]		Queue 'rndc nsec3param' requests while signing inline
 			zone changes. [GL #1205]

 5289.	[bug]		Address NULL pointer dereference in rpz.c:rpz_detach.

 			dlz_mysqldyn_mod.c. [GL #1207]
 5285.	[port]		win32: implement "-T maxudpXXX". [GL #837]
 5284.	[func]		Added +unexpected command line option to dig.
 			By default, dig won't accept a reply from a source
 			other than the one to which it sent the query.
 			Invoking dig with +unexpected argument will allow it
 			to process replies from unexpected sources.
 5283.	[bug]		When a response-policy zone expires, ensure that
 			its policies are removed from the RPZ summary
 			database. [GL #1146]
 5282.	[bug]		Fixed a bug in searching for possible wildcard matches
 			for query names in the RPZ summary database. [GL #1146]
 5281.	[cleanup]	Don't escape commas when reporting named's command
 			line. [GL #1189]
 5280.	[protocol]	Add support for displaying EDNS option LLQ. [GL #1201]
 5279.	[bug]		When loading, reject zones containing CDS or CDNSKEY
 			RRsets at the zone apex if they would cause DNSSEC
 			validation failures if published in the parent zone
 			as the DS RRset.  [GL #1187]
 5278.	[func]		Add YAML output formats for dig, mdig and delv;
 			use the "+yaml" option to enable. [GL #1145]
 	--- 9.15.3 released ---
 5277.	[bug]		Cache DB statistics could underflow when serve-stale
 			was in use, because of a bug in counter maintenance
 			when RRsets become stale.
 			Functions for dumping statistics have been updated
 			to dump active, stale, and ancient statistic
 			counters.  Ancient RRset counters are prefixed
 			with '~'; stale RRset counters are still prefixed
 			with '#'. [GL #602]
 5276.	[func]		DNSSEC Lookaside Validation (DLV) is now obsolete;

 CODE OF CONDUCT
 BIND 9 Code of Conduct
 Like the technical community as a whole, the BIND 9 team and community is
 made up of a mixture of professionals and volunteers from all over the
 world, working on every aspect of the mission - including mentorship,
 teaching, and connecting people.
 Diversity is one of our huge strengths, but it can also lead to
 communication issues and unhappiness. To that end, we have a few ground
 rules that we ask people to adhere to. This code applies equally to the
 core development team, open source contributors and those seeking help and
 guidance.
 This isn't an exhaustive list of things that you can't do. Rather, take it
 in the spirit in which it's intended - a guide to make it easier to enrich
 all of us and the technical communities in which we participate.
 This code of conduct applies to all spaces managed by the BIND 9 project
 or Internet Systems Consortium. This includes chat, the mailing lists, the
 issue tracker, and any other fora created by the project team which the
 community uses for communication. In addition, violations of this code
 outside these spaces may affect a person's ability to participate within
 them.
 If you believe someone is violating the code of conduct, we ask that you
 report it by emailing conduct@isc.org. For more details please see our
 Reporting Guidelines.
  * Be friendly and patient.
  * Be welcoming. We strive to be a community that welcomes and supports
    people of all backgrounds and identities. This includes, but is not
    limited to members of any race, ethnicity, culture, national origin,
    colour, immigration status, social and economic class, educational
    level, sex, sexual orientation, gender identity and expression, age,
    size, family status, political belief, religion, and mental and
    physical ability.
  * Be considerate. Your work will be used by other people, and you in
    turn will depend on the work of others. Any decision you take will
    affect users and colleagues, and you should take those consequences
    into account when making decisions. Remember that we're a world-wide
    community, so you might not be communicating in someone else's primary
    language.
  * Be respectful. Not all of us will agree all the time, but disagreement
    is no excuse for poor behavior and poor manners. We might all
    experience some frustration now and then, but we cannot allow that
    frustration to turn into a personal attack. It's important to remember
    that a community where people feel uncomfortable or threatened is not
    a productive one. Members of the BIND 9 community should be respectful
    when dealing with other members as well as with people outside the
    BIND 9 community.
  * Be careful in the words that you choose. We are a community of
    professionals, and we conduct ourselves professionally. Be kind to
    others. Do not insult or put down other participants. Harassment and
    other exclusionary behavior aren't acceptable. This includes, but is
    not limited to:
      + Violent threats or language directed against another person.
      + Discriminatory jokes and language.
      + Posting sexually explicit or violent material.
      + Posting (or threatening to post) other people's personally
        identifying information ("doxing").
      + Personal insults, especially those using racist or sexist terms.
      + Unwelcome sexual attention.
      + Advocating for, or encouraging, any of the above behavior.
      + Repeated harassment of others. In general, if someone asks you to
        stop, then stop.
  * When we disagree, try to understand why. Disagreements, both social
    and technical, happen all the time and BIND 9 is no exception. It is
    important that we resolve disagreements and differing views
    constructively. Remember that we're different. The strength of BIND 9
    comes from its varied community, people from a wide range of
    backgrounds. Different people have different perspectives on issues.
    Being unable to understand why someone holds a viewpoint doesn't mean
    that they're wrong. Don't forget that it is human to err and blaming
    each other doesn't get us anywhere. Instead, focus on helping to
    resolve issues and learning from mistakes.

 HISTORY
 Functional enhancements from prior major releases of BIND 9
 BIND 9.14
 BIND 9.14 (a stable branch based on the 9.13 development branch) includes
 a number of changes from BIND 9.12 and earlier releases. New features
 include:
  * A new "plugin" mechanism has been added to allow query functionality
    to be extended using dynamically loadable libraries. The "filter-aaaa"
    feature has been removed from named and is now implemented as a
    plugin.
  * Socket and task code has been refactored to improve performance.
  * QNAME minimization, as described in RFC 7816, is now supported.
  * "Root key sentinel" support, enabling validating resolvers to indicate
    via a special query which trust anchors are configured for the root
    zone.
  * Secondary zones can now be configured as "mirror" zones; their
    contents are transferred in as with traditional slave zones, but are
    subject to DNSSEC validation and are not treated as authoritative data
    when answering. This makes it easier to configure a local copy of the
    root zone as described in RFC 7706.
  * The "validate-except" option allows configuration of domains below
    which DNSSEC validation should not be performed.
  * The default value of "dnssec-validation" is now "auto".
  * IDNA2008 is now supported when linking with libidn2.
  * "named -V" now outputs the default paths for files used by named and
    other tools.
 In addition, workarounds that were formerly in place to enable resolution
 of domains whose authoritative servers did not respond to EDNS queries
 have been removed. See https://dnsflagday.net for more details.
 Cryptographic support has been modernized. BIND now uses the best
 available pseudo-random number generator for the platform on which it's
 built. Very old versions of OpenSSL are no longer supported. Cryptography
 is now mandatory: building BIND without DNSSEC is no longer supported.
 Special code to support certain legacy operating systems has also been
 removed; see the file PLATFORMS.md for details of supported platforms. In
 addition to OpenSSL, BIND now requires support for IPv6, threads, and
 standard atomic operations provided by the C compiler.
 BIND 9.12
 BIND 9.12 includes a number of changes from BIND 9.11 and earlier
 releases. New features include:
  * named and related libraries have been substantially refactored for
    improved query performance -- particularly on delegation heavy zones
    -- and for improved readability, maintainability, and testability.
  * Code implementing the name server query processing logic has been
    moved into a new libns library, for easier testing and use in tools
    other than named.
  * Cached, validated NSEC and other records can now be used to synthesize
    NXDOMAIN responses.
  * The DNS Response Policy Service API (DNSRPS) is now supported.
  * Setting 'max-journal-size default' now limits the size of journal
    files to twice the size of the zone.
  * dnstap-read -x prints a hex dump of the wire format of each logged DNS
    message.
  * dnstap output files can now be configured to roll automatically when
    reaching a given size.
  * Log file timestamps can now also be formatted in ISO 8601 (local) or
    ISO 8601 (UTC) formats.
  * Logging channels and dnstap output files can now be configured to use
    a timestamp as the suffix when rolling to a new file.
  * 'named-checkconf -l' lists zones found in named.conf.
  * Added support for the EDNS Padding and Keepalive options.
  * 'new-zones-directory' option sets the location where the configuration
    data for zones added by rndc addzone is stored.
  * The default key algorithm in rndc-confgen is now hmac-sha256.
  * filter-aaaa-on-v4 and filter-aaaa-on-v6 options are now available by
    default without a configure option.
  * The obsolete isc-hmac-fixup command has been removed.

 * IDNA2008 is now supported when linking with `libidn2`.
 * "named -V" now outputs the default paths for files used by named
  and other tools.
 In addition, workarounds that were formerly in place to enable resolution
 of domains whose authoritative servers did not respond to EDNS queries
 have been removed. See [https://dnsflagday.net](https://dnsflagday.net)
 for more details.
 Cryptographic support has been modernized. BIND now uses the
 best available pseudo-random number generator for the platform on which
 it's built. Very old versions of OpenSSL are no longer supported.
 Cryptography is now mandatory: building BIND without DNSSEC is no
 longer supported.
 Special code to support certain legacy operating systems has also
 been removed; see the file [PLATFORMS.md](PLATFORMS.md) for details
 of supported platforms. In addition to OpenSSL, BIND now requires
 support for IPv6, threads, and standard atomic operations provided
 by the C compiler.
 #### BIND 9.12
 BIND 9.12 includes a number of changes from BIND 9.11 and earlier releases.
 New features include:
 * `named` and related libraries have been substantially refactored for
  improved query performance -- particularly on delegation heavy zones --
  and for improved readability, maintainability, and testability.
 * Code implementing the name server query processing logic has been moved
  into a new `libns` library, for easier testing and use in tools other
  than `named`.
 * Cached, validated NSEC and other records can now be used to synthesize
  NXDOMAIN responses.
 * The DNS Response Policy Service API (DNSRPS) is now supported.
 * Setting `'max-journal-size default'` now limits the size of journal files
  to twice the size of the zone.
 * `dnstap-read -x` prints a hex dump of the wire format of each logged
  DNS message.
 * `dnstap` output files can now be configured to roll automatically when
  reaching a given size.
 * Log file timestamps can now also be formatted in ISO 8601 (local) or ISO
  8601 (UTC) formats.
 * Logging channels and `dnstap` output files can now be configured to use a
  timestamp as the suffix when rolling to a new file.
 * `'named-checkconf -l'` lists zones found in `named.conf`.
 * Added support for the EDNS Padding and Keepalive options.
 * 'new-zones-directory' option sets the location where the configuration
  data for zones added by rndc addzone is stored.
 * The default key algorithm in `rndc-confgen` is now hmac-sha256.
 * `filter-aaaa-on-v4` and `filter-aaaa-on-v6` options are now available
  by default without a configure option.
 * The obsolete `isc-hmac-fixup` command has been removed.

 ## Platform quirks
 ### ARM
 If the compilation ends with following error:
 ```
 Error: selected processor does not support `yield' in ARM mode
 ```
 You will need to set `-march` compiler option to `native`, so the compiler
 recognizes `yield` assembler instruction.  The proper way to set `-march=native`
 would be to put it into `CFLAGS`, e.g. run `./configure` like this:
 `CFLAGS="-march=native -Os -g" ./configure` plus your usual options.
 If that doesn't work, you can enforce the minimum CPU and FPU (taken from Debian
 armhf documentation):
 * The lowest worthwhile CPU implementation is Armv7-A, therefore the recommended
  build option is `-march=armv7-a`.
 * FPU should be set at VFPv3-D16 as they represent the miminum specification of
  the processors to support here, therefore the recommended build option is
  `-mfpu=vfpv3-d16`.
 The configure command should look like this:
 ```
 CFLAGS="-march=armv7-a -mfpu=vfpv3-d16 -Os -g" ./configure
 ```

  * The default value of "dnssec-validation" is now "auto".
  * IDNA2008 is now supported when linking with libidn2.
 In addition, workarounds that were formerly in place to enable resolution
 of domains whose authoritative servers did not respond to EDNS queries
 have been removed. See https://dnsflagday.net for more details.
 Cryptographic support has been modernized. BIND now uses the best
 available pseudo-random number generator for the platform on which it's
 built. Very old versions of OpenSSL are no longer supported. Cryptography
 is now mandatory: building BIND without DNSSEC is now longer supported.
 Special code to support certain legacy operating systems has also been
 removed; see the file PLATFORMS.md for details of supported platforms. In
 addition to OpenSSL, BIND now requires support for IPv6, threads, and
 standard atomic operations provided by the C compiler.

 Portions of BIND that are written in Python, including dnssec-keymgr,

 argparse, ply and distutils.core modules to be available. argparse is a

 Compile-time options
 To see a full list of configuration options, run configure --help.
 On most platforms, BIND 9 is built with multithreading support, allowing
 it to take advantage of multiple CPUs. You can configure this by
 specifying --enable-threads or --disable-threads on the configure command
 line. The default is to enable threads, except on some older operating
 systems on which threads are known to have had problems in the past.
 (Note: Prior to BIND 9.10, the default was to disable threads on Linux
 systems; this has now been reversed. On Linux systems, the threaded build
 is known to change BIND's behavior with respect to file permissions; it
 may be necessary to specify a user with the -u option when running named.)
 To build shared libraries, specify --with-libtool on the configure command

 information which is confidential or security sensitive.
 To look up a GitLab issue by its number, use the URL https://
 gitlab.isc.org/isc-projects/bind9/issues/NNN. To look up a merge request,
 use https://gitlab.isc.org/isc-projects/bind9/merge_requests/NNN.
 In rare cases, an issue or merge request number may be followed with the
 letter "P". This indicates that the information is in the private ISC
 GitLab instance, which is not visible to the public.

 In addition, workarounds that were formerly in place to enable resolution
 of domains whose authoritative servers did not respond to EDNS queries
 have been removed. See [https://dnsflagday.net](https://dnsflagday.net)
 for more details.
 Cryptographic support has been modernized. BIND now uses the
 best available pseudo-random number generator for the platform on which
 it's built. Very old versions of OpenSSL are no longer supported.
 Cryptography is now mandatory: building BIND without DNSSEC is now
 longer supported.
 Special code to support certain legacy operating systems has also
 been removed; see the file [PLATFORMS.md](PLATFORMS.md) for details
 of supported platforms. In addition to OpenSSL, BIND now requires
 support for IPv6, threads, and standard atomic operations provided
 by the C compiler.

 information which is confidential or security sensitive.
 To look up a GitLab issue by its number, use the URL
 [https://gitlab.isc.org/isc-projects/bind9/issues/NNN](https://gitlab.isc.org/isc-projects/bind9/issues).
 To look up a merge request, use
 [https://gitlab.isc.org/isc-projects/bind9/merge_requests/NNN](https://gitlab.isc.org/isc-projects/bind9/merge_requests).
 In rare cases, an issue or merge request number may be followed with the
 letter "P". This indicates that the information is in the private ISC
 GitLab instance, which is not visible to the public.

      If <span class="command"><strong>nslookup</strong></span> has been built with IDN (internationalized
      domain name) support, it can accept and display non-ASCII domain names.
      <span class="command"><strong>nslookup</strong></span> appropriately converts character encoding of
      domain name before sending a request to DNS server or displaying a
      reply from the server.
      If you'd like to turn off the IDN support for some reason, define
      the <code class="envar">IDN_DISABLE</code> environment variable.
      The IDN support is disabled if the variable is set when

 .PP
 The input keys can be specified in a number of ways:
 .PP
 By default,
 \fBdnssec\-dsfromkey\fR
 reads a key file named like
 Knnnn\&.+aaa+iiiii\&.key, as generated by
 \fBdnssec\-keygen\fR\&.
 .PP
 With the
 \fB\-f \fR\fB\fIfile\fR\fR
 option,
 \fBdnssec\-dsfromkey\fR
 reads keys from a zone file or partial zone file (which can contain just the DNSKEY records)\&.
 .PP
 With the
 \fB\-s\fR
 option,
 \fBdnssec\-dsfromkey\fR
 reads a
 keyset\-
 file, as generated by
 \fBdnssec\-keygen\fR\fB\-C\fR\&.
