 ### 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](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.
