-### CVE-specific actions
-
-  - [ ] Assign a CVE identifier
-  - [ ] Determine CVSS score
-  - [ ] Determine the range of BIND versions affected (including the Subscription Edition)
-  - [ ] Determine whether workarounds for the problem exists
-  - [ ] Create a draft of the security advisory and put the information above in there
-  - [ ] Prepare a detailed description of the problem which should include the following by default:
-      - instructions for reproducing the problem (a system test is good enough)
-      - explanation of code flow which triggers the problem (a system test is *not* good enough)
-  - [ ] Prepare a private merge request containing the following items in separate commits:
-      - a test for the issue (may be moved to a separate merge request for deferred merging)
-      - a fix for the issue
-      - documentation updates (`CHANGES`, release notes, anything else applicable)
-  - [ ] Ensure the merge request from the previous step is reviewed by SWENG staff and has no outstanding discussions
-  - [ ] Ensure the documentation changes introduced by the merge request addressing the problem are reviewed by Support and Marketing staff
-  - [ ] Prepare backports of the merge request addressing the problem for all affected (and still maintained) BIND branches (backporting might affect the issue's scope and/or description)
-  - [ ] Prepare a standalone patch for the last stable release of each affected (and still maintained) BIND branch
-
-### Release-specific actions
-
-  - [ ] Create/update the private issue containing links to fixes & reproducers for all CVEs fixed in a given release cycle
-  - [ ] Reserve a block of `CHANGES` placeholders once the complete set of vulnerabilities fixed in a given release cycle is determined
-  - [ ] Ensure the merge requests containing CVE fixes are merged into `security-*` branches in CVE identifier order
-
-### Post-disclosure actions
-
-  - [ ] Merge a regression test reproducing the bug into all affected (and still maintained) BIND branches

+### Functional enhancements from prior major releases of BIND 9
+
+#### BIND 9.16
+
+BIND 9.16 (a stable branch based on the 9.15 development branch)
+includes a number of changes from BIND 9.14 and earlier releases.
+New features include:
+
+* New `dnssec-policy` statement to configure a key and signing policy
+  for zones, enabling automatic key regeneration and rollover.
+* New network manager based on `libuv`.
+* Added support for the new GeoIP2 geolocation API, `libmaxminddb`.
+* Improved DNSSEC trust anchor configuration using the `trust-anchors`
+  statement, permitting configuration of trust anchors in DS as well as
+  DNSKEY format.
+* YAML output for `dig`, `mdig`, and `delv`.
+
+#### 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](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.
+
+#### BIND 9.11
+
+BIND 9.11.0 includes a number of changes from BIND 9.10 and earlier
+releases.  New features include:
+
+- Added support for Catalog Zones, a new method for provisioning servers: a
+  list of zones to be served is stored in a DNS zone, along with their
+  configuration parameters. Changes to the catalog zone are propagated to
+  slaves via normal AXFR/IXFR, whereupon the zones that are listed in it
+  are automatically added, deleted or reconfigured.
+- Added support for "dnstap", a fast and flexible method of capturing and
+  logging DNS traffic.
+- Added support for "dyndb", a new API for loading zone data from an
+  external database, developed by Red Hat for the FreeIPA project.
+- "fetchlimit" quotas are now compiled in by default.  These are for the
+  use of recursive resolvers that are are under high query load for domains
+  whose authoritative servers are nonresponsive or are experiencing a
+  denial of service attack:
+    - "fetches-per-server" limits the number of simultaneous queries that
+      can be sent to any single authoritative server.  The configured value
+      is a starting point; it is automatically adjusted downward if the
+      server is partially or completely non-responsive. The algorithm used
+      to adjust the quota can be configured via the "fetch-quota-params"
+      option.
+    - "fetches-per-zone" limits the number of simultaneous queries that can
+      be sent for names within a single domain.  (Note: Unlike
+      "fetches-per-server", this value is not self-tuning.)
+    - New stats counters have been added to count queries spilled due to
+      these quotas.
+- Added a new "dnssec-keymgr" key mainenance utility, which can generate or
+  update keys as needed to ensure that a zone's keys match a defined DNSSEC
+  policy.
+- The experimental "SIT" feature in BIND 9.10 has been renamed "COOKIE" and
+  is no longer optional. EDNS COOKIE is a mechanism enabling clients to
+  detect off-path spoofed responses, and servers to detect spoofed-source
+  queries.  Clients that identify themselves using COOKIE options are not
+  subject to response rate limiting (RRL) and can receive larger UDP
+  responses.
+- SERVFAIL responses can now be cached for a limited time (defaulting to 1
+  second, with an upper limit of 30).  This can reduce the frequency of
+  retries when a query is persistently failing.
+- Added an "nsip-wait-recurse" switch to RPZ. This causes NSIP rules to be
+  skipped if a name server IP address isn't in the cache yet; the address
+  will be looked up and the rule will be applied on future queries.
+- Added a Python RNDC module. This allows multiple commands to sent over a
+  persistent RNDC channel, which saves time.
+- The "controls" block in named.conf can now grant read-only "rndc" access
+  to specified clients or keys. Read-only clients could, for example, check
+  "rndc status" but could not reconfigure or shut down the server.
+- "rndc" commands can now return arbitrarily large amounts of text to the
+  caller.
+- The zone serial number of a dynamically updatable zone can now be set via
+  "rndc signing -serial <number> <zonename>".  This allows inline-signing
+  zones to be set to a specific serial number.
+- The new "rndc nta" command can be used to set a Negative Trust Anchor
+  (NTA), disabling DNSSEC validation for a specific domain; this can be
+  used when responses from a domain are known to be failing validation due
+  to administrative error rather than because of a spoofing attack.
+  Negative trust anchors are strictly temporary; by default they expire
+  after one hour, but can be configured to last up to one week.
+- "rndc delzone" can now be used on zones that were not originally created
+  by "rndc addzone".
+- "rndc modzone" reconfigures a single zone, without requiring the entire
+  server to be reconfigured.
+- "rndc showzone" displays the current configuration of a zone.
+- "rndc managed-keys" can be used to check the status of RFC 5011 managed
+  trust anchors, or to force trust anchors to be refreshed.
+- "max-cache-size" can now be set to a percentage of available memory. The
+  default is 90%.
+- Update forwarding performance has been improved by allowing a single TCP
+  connection to be shared by multiple updates.
+- The EDNS Client Subnet (ECS) option is now supported for authoritative
+  servers; if a query contains an ECS option then ACLs containing "geoip"
+  or "ecs" elements can match against the the address encoded in the
+  option.  This can be used to select a view for a query, so that different
+  answers can be provided depending on the client network.
+- The EDNS EXPIRE option has been implemented on the client side, allowing
+  a slave server to set the expiration timer correctly when transferring
+  zone data from another slave server.
+- The key generation and manipulation tools (dnssec-keygen, dnssec-settime,
+  dnssec-importkey, dnssec-keyfromlabel) now take "-Psync" and "-Dsync"
+  options to set the publication and deletion times of CDS and CDNSKEY
+  parent-synchronization records.  Both named and dnssec-signzone can now
+  publish and remove these records at the scheduled times.
+- A new "minimal-any" option reduces the size of UDP responses for query
+  type ANY by returning a single arbitrarily selected RRset instead of all
+  RRsets.
+- A new "masterfile-style" zone option controls the formatting of text zone
+  files:  When set to "full", a zone file is dumped in
+  single-line-per-record format.
+- "serial-update-method" can now be set to "date". On update, the serial
+  number will be set to the current date in YYYYMMDDNN format.
+- "dnssec-signzone -N date" sets the serial number to YYYYMMDDNN.
+- "named -L <filename>" causes named to send log messages to the specified
+  file by default instead of to the system log.
+- "dig +ttlunits" prints TTL values with time-unit suffixes: w, d, h, m, s
+  for weeks, days, hours, minutes, and seconds.
+- "dig +unknownformat" prints dig output in RFC 3597 "unknown record"
+  presentation format.
+- "dig +ednsopt" allows dig to set arbitrary EDNS options on requests.
+- "dig +ednsflags" allows dig to set yet-to-be-defined EDNS flags on
+  requests.
+- "mdig" is an alternate version of dig which sends multiple pipelined TCP
+  queries to a server.  Instead of waiting for a response after sending a
+  query, it sends all queries immediately and displays responses in the
+  order received.
+- "serial-query-rate" no longer controls NOTIFY messages.  These are
+  separately controlled by "notify-rate" and "startup-notify-rate".
+- "nsupdate" now performs "check-names" processing by default on records to
+  be added.  This can be disabled with "check-names no".
+- The statistics channel now supports DEFLATE compression, reducing the
+  size of the data sent over the network when querying statistics.
+- New counters have been added to the statistics channel to track the sizes
+  of incoming queries and outgoing responses in histogram buckets, as
+  specified in RSSAC002.
+- A new NXDOMAIN redirect method (option "nxdomain-redirect") has been
+  added, allowing redirection to a specified DNS namespace instead of a
+  single redirect zone.
+- When starting up, named now ensures that no other named process is
+  already running.
+- Files created by named to store information, including "mkeys" and "nzf"
+  files, are now named after their corresponding views unless the view name
+  contains characters incompatible with use as a filename. Old style
+  filenames (based on the hash of the view name) will still work.
+
+#### BIND 9.10.0
+
+BIND 9.10.0 includes a number of changes from BIND 9.9 and earlier
+releases.  New features include:
+
+ - DNS Response-rate limiting (DNS RRL), which blunts the
+   impact of reflection and amplification attacks, is always
+   compiled in and no longer requires a compile-time option
+   to enable it.
+ - An experimental "Source Identity Token" (SIT) EDNS option
+   is now available.  Similar to DNS Cookies as invented by
+   Donald Eastlake 3rd, these are designed to enable clients
+   to detect off-path spoofed responses, and to enable servers
+   to detect spoofed-source queries.  Servers can be configured
+   to send smaller responses to clients that have not identified
+   themselves using a SIT option, reducing the effectiveness of
+   amplification attacks.  RRL processing has also been updated;
+   clients proven to be legitimate via SIT are not subject to
+   rate limiting.  Use "configure --enable-sit" to enable this
+   feature in BIND.
+ - A new zone file format, "map", stores zone data in a
+   format that can be mapped directly into memory, allowing
+   significantly faster zone loading.
+ - "delv" (domain entity lookup and validation) is a new tool
+   with dig-like semantics for looking up DNS data and performing
+   internal DNSSEC validation.  This allows easy validation in
+   environments where the resolver may not be trustworthy, and
+   assists with troubleshooting of DNSSEC problems. (NOTE:
+   In previous development releases of BIND 9.10, this utility
+   was called "delve". The spelling has been changed to avoid
+   confusion with the "delve" utility included with the Xapian
+   search engine.)
+ - Improved EDNS(0) processing for better resolver performance
+   and reliability over slow or lossy connections.
+ - A new "configure --with-tuning=large" option tunes certain
+   compiled-in constants and default settings to values better
+   suited to large servers with abundant memory.  This can
+   improve performance on such servers, but will consume more
+   memory and may degrade performance on smaller systems.
+ - Substantial improvement in response-policy zone (RPZ)
+   performance.  Up to 32 response-policy zones can be
+   configured with minimal performance loss.
+ - To improve recursive resolver performance, cache records
+   which are still being requested by clients can now be
+   automatically refreshed from the authoritative server
+   before they expire, reducing or eliminating the time
+   window in which no answer is available in the cache.
+ - New "rpz-client-ip" triggers and drop policies allowing
+   response policies based on the IP address of the client.
+ - ACLs can now be specified based on geographic location
+   using the MaxMind GeoIP databases.  Use "configure
+   --with-geoip" to enable.
+ - Zone data can now be shared between views, allowing
+   multiple views to serve the same zones authoritatively
+   without storing multiple copies in memory.
+ - New XML schema (version 3) for the statistics channel
+   includes many new statistics and uses a flattened XML tree
+   for faster parsing. The older schema is now deprecated.
+ - A new stylesheet, based on the Google Charts API, displays
+   XML statistics in charts and graphs on javascript-enabled
+   browsers.
+ - The statistics channel can now provide data in JSON
+   format as well as XML.
+ - New stats counters track TCP and UDP queries received
+   per zone, and EDNS options received in total.
+ - The internal and export versions of the BIND libraries
+   (libisc, libdns, etc) have been unified so that external
+   library clients can use the same libraries as BIND itself.
+ - A new compile-time option, "configure --enable-native-pkcs11",
+   allows BIND 9 cryptography functions to use the PKCS#11 API
+   natively, so that BIND can drive a cryptographic hardware
+   service module (HSM) directly instead of using a modified
+   OpenSSL as an intermediary. (Note: This feature requires an
+   HSM to have a full implementation of the PKCS#11 API; many
+   current HSMs only have partial implementations. The new
+   "pkcs11-tokens" command can be used to check API completeness.
+   Native PKCS#11 is known to work with the Thales nShield HSM
+   and with SoftHSM version 2 from the Open DNSSEC project.)
+ - The new "max-zone-ttl" option enforces maximum TTLs for
+   zones. This can simplify the process of rolling DNSSEC keys
+   by guaranteeing that cached signatures will have expired
+   within the specified amount of time.
+ - "dig +subnet" sends an EDNS CLIENT-SUBNET option when
+   querying.
+ - "dig +expire" sends an EDNS EXPIRE option when querying.
+   When this option is sent with an SOA query to a server
+   that supports it, it will report the expiry time of
+   a slave zone.
+ - New "dnssec-coverage" tool to check DNSSEC key coverage
+   for a zone and report if a lapse in signing coverage has
+   been inadvertently scheduled.
+ - Signing algorithm flexibility and other improvements
+   for the "rndc" control channel.
+ - "named-checkzone" and "named-compilezone" can now read
+   journal files, allowing them to process dynamic zones.
+ - Multiple DLZ databases can now be configured.  Individual
+   zones can be configured to be served from a specific DLZ
+   database.  DLZ databases now serve zones of type "master"
+   and "redirect".
+ - "rndc zonestatus" reports information about a specified zone.
+ - "named" now listens on IPv6 as well as IPv4 interfaces
+   by default.
+ - "named" now preserves the capitalization of names
+   when responding to queries: for instance, a query for
+   "example.com" may be answered with "example.COM" if the
+   name was configured that way in the zone file.  Some
+   clients have a bug causing them to depend on the older
+   behavior, in which the case of the answer always matched
+   the case of the query, rather than the case of the name
+   configured in the DNS.  Such clients can now be specified
+   in the new "no-case-compress" ACL; this will restore the
+   older behavior of "named" for those clients only.
+ - new "dnssec-importkey" command allows the use of offline
+   DNSSEC keys with automatic DNSKEY management.
+ - New "named-rrchecker" tool to verify the syntactic
+   correctness of individual resource records.
+ - When re-signing a zone, the new "dnssec-signzone -Q" option
+   drops signatures from keys that are still published but are
+   no longer active.
+ - "named-checkconf -px" will print the contents of configuration
+   files with the shared secrets obscured, making it easier to
+   share configuration (e.g. when submitting a bug report)
+   without revealing private information.
+ - "rndc scan" causes named to re-scan network interfaces for
+   changes in local addresses.
+ - On operating systems with support for routing sockets,
+   network interfaces are re-scanned automatically whenever
+   they change.
+ - "tsig-keygen" is now available as an alternate command
+   name to use for "ddns-confgen".
+
+#### BIND 9.9.0
+
+BIND 9.9.0 includes a number of changes from BIND 9.8 and earlier
+releases.  New features include:
+
+- Inline signing, allowing automatic DNSSEC signing of
+  master zones without modification of the zonefile, or
+  "bump in the wire" signing in slaves.
+- NXDOMAIN redirection.
+- New 'rndc flushtree' command clears all data under a given
+  name from the DNS cache.
+- New 'rndc sync' command dumps pending changes in a dynamic
+  zone to disk without a freeze/thaw cycle.
+- New 'rndc signing' command displays or clears signing status
+  records in 'auto-dnssec' zones.
+- NSEC3 parameters for 'auto-dnssec' zones can now be set prior
+  to signing, eliminating the need to initially sign with NSEC.
+- Startup time improvements on large authoritative servers.
+- Slave zones are now saved in raw format by default.
+- Several improvements to response policy zones (RPZ).
+- Improved hardware scalability by using multiple threads
+  to listen for queries and using finer-grained client locking
+- The 'also-notify' option now takes the same syntax as
+  'masters', so it can used named masterlists and TSIG keys.
+- 'dnssec-signzone -D' writes an output file containing only DNSSEC
+  data, which can be included by the primary zone file.
+- 'dnssec-signzone -R' forces removal of signatures that are
+  not expired but were created by a key which no longer exists.
+- 'dnssec-signzone -X' allows a separate expiration date to
+  be specified for DNSKEY signatures from other signatures.
+- New '-L' option to dnssec-keygen, dnssec-settime, and
+  dnssec-keyfromlabel sets the default TTL for the key.
+- dnssec-dsfromkey now supports reading from standard input,
+  to make it easier to convert DNSKEY to DS.
+- RFC 1918 reverse zones have been added to the empty-zones
+  table per RFC 6303.
+- Dynamic updates can now optionally set the zone's SOA serial
+  number to the current UNIX time.
+- DLZ modules can now retrieve the source IP address of
+  the querying client.
+- 'request-ixfr' option can now be set at the per-zone level.
+- 'dig +rrcomments' turns on comments about DNSKEY records,
+  indicating their key ID, algorithm and function
+- Simplified nsupdate syntax and added readline support
+
+#### BIND 9.8.0
+
+BIND 9.8.0 includes a number of changes from BIND 9.7 and earlier
+releases.  New features include:
+
+- Built-in trust anchor for the root zone, which can be
+  switched on via "dnssec-validation auto;"
+- Support for DNS64.
+- Support for response policy zones (RPZ).
+- Support for writable DLZ zones.
+- Improved ease of configuration of GSS/TSIG for
+  interoperability with Active Directory
+- Support for GOST signing algorithm for DNSSEC.
+- Removed RTT Banding from server selection algorithm.
+- New "static-stub" zone type.
+- Allow configuration of resolver timeouts via
+  "resolver-query-timeout" option.
+- The DLZ "dlopen" driver is now built by default.
+- Added a new include file with function typedefs
+  for the DLZ "dlopen" driver.
+- Made "--with-gssapi" default.
+- More verbose error reporting from DLZ LDAP.
+
+#### BIND 9.7.0
+
+BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
+releases.  Most are intended to simplify DNSSEC configuration.
+New features include:
+
+- Fully automatic signing of zones by "named".
+- Simplified configuration of DNSSEC Lookaside Validation (DLV).
+- Simplified configuration of Dynamic DNS, using the "ddns-confgen"
+  command line tool or the "local" update-policy option.  (As a side
+  effect, this also makes it easier to configure automatic zone
+  re-signing.)
+- New named option "attach-cache" that allows multiple views to
+  share a single cache.
+- DNS rebinding attack prevention.
+- New default values for dnssec-keygen parameters.
+- Support for RFC 5011 automated trust anchor maintenance
+- Smart signing: simplified tools for zone signing and key
+  maintenance.
+- The "statistics-channels" option is now available on Windows.
+- A new DNSSEC-aware libdns API for use by non-BIND9 applications
+- On some platforms, named and other binaries can now print out
+  a stack backtrace on assertion failure, to aid in debugging.
+- A "tools only" installation mode on Windows, which only installs
+  dig, host, nslookup and nsupdate.
+- Improved PKCS#11 support, including Keyper support and explicit
+  OpenSSL engine selection.
+
+#### BIND 9.6.0
+
+- Full NSEC3 support
+- Automatic zone re-signing
+- New update-policy methods tcp-self and 6to4-self
+- The BIND 8 resolver library, libbind, has been removed from the BIND 9
+  distribution and is now available as a separate download.
+- Change the default pid file location from /var/run to
+  /var/run/{named,lwresd} for improved chroot/setuid support.
+
+#### BIND 9.5.0
+
+- GSS-TSIG support (RFC 3645).
+- DHCID support.
+- Experimental http server and statistics support for named via xml.
+- More detailed statistics counters including those supported in BIND 8.
+- Faster ACL processing.
+- Use Doxygen to generate internal documentation.
+- Efficient LRU cache-cleaning mechanism.
+- NSID support.
+
+BIND 9.4.0
+
+- Implemented "additional section caching (or acache)", an internal cache
+  framework for additional section content to improve response performance.
+  Several configuration options were provided to control the behavior.
+- New notify type 'master-only'.  Enable notify for master zones only.
+- Accept 'notify-source' style syntax for query-source.
+- rndc now allows addresses to be set in the server clauses.
+- New option "allow-query-cache".  This lets "allow-query" be used to
+  specify the default zone access level rather than having to have every
+  zone override the global value.  "allow-query-cache" can be set at both
+  the options and view levels.  If "allow-query-cache" is not set then
+  "allow-recursion" is used if set, otherwise "allow-query" is used if set
+  unless "recursion no;" is set in which case "none;" is used, otherwise
+  the default (localhost; localnets;) is used.
+- rndc: the source address can now be specified.
+- ixfr-from-differences now takes master and slave in addition to yes and
+  no at the options and view levels.
+- Allow the journal's name to be changed via named.conf.
+- 'rndc notify zone [class [view]]' resend the NOTIFY messages for the
+  specified zone.
+- 'dig +trace' now randomly selects the next servers to try.  Report if
+  there is a bad delegation.
+- Improve check-names error messages.
+- Make public the function to read a key file, dst_key_read_public().
+- dig now returns the byte count for axfr/ixfr.
+- allow-update is now settable at the options / view level.
+- named-checkconf now checks the logging configuration.
+- host now can turn on memory debugging flags with '-m'.
+- Don't send notify messages to self.
+- Perform sanity checks on NS records which refer to 'in zone' names.
+- New zone option "notify-delay".  Specify a minimum delay between sets of
+  NOTIFY messages.
+- Extend adjusting TTL warning messages.
+- Named and named-checkzone can now both check for non-terminal wildcard
+  records.
+- "rndc freeze/thaw" now freezes/thaws all zones.
+- named-checkconf now check acls to verify that they only refer to existing
+  acls.
+- The server syntax has been extended to support a range of servers.
+- Report differences between hints and real NS rrset and associated address
+  records.
+- Preserve the case of domain names in rdata during zone transfers.
+- Restructured the data locking framework using architecture dependent
+  atomic operations (when available), improving response performance on
+  multi-processor machines significantly.  x86, x86_64, alpha, powerpc, and
+  mips are currently supported.
+- UNIX domain controls are now supported.
+- Add support for additional zone file formats for improving loading
+  performance.  The masterfile-format option in named.conf can be used to
+  specify a non-default format.  A separate command named-compilezone was
+  provided to generate zone files in the new format.  Additionally, the -I
+  and -O options for dnssec-signzone specify the input and output formats.
+- dnssec-signzone can now randomize signature end times (dnssec-signzone -j
+  jitter).
+- Add support for CH A record.
+- Add additional zone data constancy checks.  named-checkzone has extended
+  checking of NS, MX and SRV record and the hosts they reference.  named
+  has extended post zone load checks.  New zone options: check-mx and
+  integrity-check.
+- edns-udp-size can now be overridden on a per server basis.
+- dig can now specify the EDNS version when making a query.
+- Added framework for handling multiple EDNS versions.
+- Additional memory debugging support to track size and mctx arguments.
+- Detect duplicates of UDP queries we are recursing on and drop them.  New
+  stats category "duplicates".
+- "USE INTERNAL MALLOC" is now runtime selectable.
+- The lame cache is now done on a <qname,qclass,qtype> basis as some
+  servers only appear to be lame for certain query types.
+- Limit the number of recursive clients that can be waiting for a single
+  query (<qname,qtype,qclass>) to resolve.  New options clients-per-query
+  and max-clients-per-query.
+- dig: report the number of extra bytes still left in the packet after
+  processing all the records.
+- Support for IPSECKEY rdata type.
+- Raise the UDP receive buffer size to 32k if it is less than 32k.
+- x86 and x86_64 now have separate atomic locking implementations.
+- named-checkconf now validates update-policy entries.
+- Attempt to make the amount of work performed in a iteration self tuning.
+  The covers nodes clean from the cache per iteration, nodes written to
+  disk when rewriting a master file and nodes destroyed per iteration when
+  destroying a zone or a cache.
+- ISC string copy API.
+- Automatic empty zone creation for D.F.IP6.ARPA and friends.  Note: RFC
+  1918 zones are not yet covered by this but are likely to be in a future
+  release.
+- New options: empty-server, empty-contact, empty-zones-enable and
+  disable-empty-zone.
+- dig now has a '-q queryname' and '+showsearch' options.
+- host/nslookup now continue (default)/fail on SERVFAIL.
+- dig now warns if 'RA' is not set in the answer when 'RD' was set in the
+  query.  host/nslookup skip servers that fail to set 'RA' when 'RD' is set
+  unless a server is explicitly set.
+- Integrate contributed DLZ code into named.
+- Integrate contributed IDN code from JPNIC.
+- libbind: corresponds to that from BIND 8.4.7.
+
+#### BIND 9.3.0
+
+- DNSSEC is now DS based (RFC 3658).
+- DNSSEC lookaside validation.
+- check-names is now implemented.
+- rrset-order is more complete.
+- IPv4/IPv6 transition support, dual-stack-servers.
+- IXFR deltas can now be generated when loading master files,
+  ixfr-from-differences.
+- It is now possible to specify the size of a journal, max-journal-size.
+- It is now possible to define a named set of master servers to be used in
+  masters clause, masters.
+- The advertised EDNS UDP size can now be set, edns-udp-size.
+- allow-v6-synthesis has been obsoleted.
+- Zones containing MD and MF will now be rejected.
+- dig, nslookup name. now report "Not Implemented" as NOTIMP rather than
+  NOTIMPL.  This will have impact on scripts that are looking for NOTIMPL.
+- libbind: corresponds to that from BIND 8.4.5.
+
+#### BIND 9.2.0
+
+- The size of the cache can now be limited using the "max-cache-size"
+  option.
+- The server can now automatically convert RFC1886-style recursive lookup
+  requests into RFC2874-style lookups, when enabled using the new option
+  "allow-v6-synthesis".  This allows stub resolvers that support AAAA
+  records but not A6 record chains or binary labels to perform lookups in
+  domains that make use of these IPv6 DNS features.
+- Performance has been improved.
+- The man pages now use the more portable "man" macros rather than the
+  "mandoc" macros, and are installed by "make install".
+- The named.conf parser has been completely rewritten.  It now supports
+  "include" directives in more places such as inside "view" statements, and
+  it no longer has any reserved words.
+- The "rndc status" command is now implemented.
+- rndc can now be configured automatically.
+- A BIND 8 compatible stub resolver library is now included in lib/bind.
+- OpenSSL has been removed from the distribution.  This means that to use
+  DNSSEC, OpenSSL must be installed and the --with-openssl option must be
+  supplied to configure.  This does not apply to the use of TSIG, which
+  does not require OpenSSL.
+- The source distribution now builds on Windows.  See
+  win32utils/readme1.txt and win32utils/win32-build.txt for details.
+- This distribution also includes a new lightweight stub resolver library
+  and associated resolver daemon that fully support forward and reverse
+  lookups of both IPv4 and IPv6 addresses.  This library is considered
+  experimental and is not a complete replacement for the BIND 8 resolver
+  library.  Applications that use the BIND 8 `res_*` functions to perform
+  DNS lookups or dynamic updates still need to be linked against the BIND 8
+  libraries.  For DNS lookups, they can also use the new "getrrsetbyname()"
+  API.
+- BIND 9.2 is capable of acting as an authoritative server for DNSSEC
+  secured zones.  This functionality is believed to be stable and complete
+  except for lacking support for verifications involving wildcard records
+  in secure zones.
+- When acting as a caching server, BIND 9.2 can be configured to perform
+  DNSSEC secure resolution on behalf of its clients.  This part of the
+  DNSSEC implementation is still considered experimental.  For detailed
+  information about the state of the DNSSEC implementation, see the file
+  doc/misc/dnssec.

 At a minimum, BIND requires a Unix or Linux system with an ANSI C compiler,
 basic POSIX support, and a 64-bit integer type. BIND also requires the
-`libuv` asynchronous I/O library, the `nghttp2` HTTP/2 library, the
-`jemalloc` memory allocation library, and the OpenSSL cryptography
-library.  On Linux, BIND requires the `libcap` library to set process
-privileges, though this requirement can be overridden by disabling
-capability support at compile time. See [Compile-time options](#opts)
