        - Perform TLS SNI indication of the host that is being contacted
          for DNS over TLS service.  It sets the configured tls auth name.

        - Disable minimal-responses in ipsecmod unit tests.
        - Added serve-expired-ttl and serve-expired-ttl-reset options.

   27 August 2018: Wouter
        - Set defaults to yes for a number of options to increase speed and
          resilience of the server.  The so-reuseport, harden-below-nxdomain,
          and minimal-responses options are enabled by default.  They used
          to be disabled by default, waiting to make sure they worked.  They
          are enabled by default now, and can be disabled explicitly by
          setting them to "no" in the unbound.conf config file.  The reuseport
          and minimal options increases speed of the server, and should be
          otherwise harmless.  The harden-below-nxdomain option works well
          together with the recently default enabled qname minimisation, this
          causes more fetches to use information from the cache.
        - next release is called 1.8.0.
        - Fix lintflags for lint on FreeBSD.

   22 August 2018: George
        - #4140: Expose repinfo (comm_reply) to the inplace_callbacks. This
          gives access to reply information for the client's communication
          point when the callback is called before the mesh state (modules).
          Changes to C and Python's inplace_callback signatures were also
          necessary.

   21 August 2018: Wouter
        - log-local-actions: yes option for unbound.conf that logs all the
          local zone actions, a patch from Saksham Manchanda (Secure64).
        - #4146: num.query.subnet and num.query.subnet_cache counters.
        - Fix only misc failure from log-servfail when val-log-level is not
          enabled.

   17 August 2018: Ralph
        - Fix classification for QTYPE=CNAME queries when QNAME minimisation is
          enabled.

   17 August 2018: Wouter
        - Set libunbound to increase current, because the libunbound change
          to the event callback function signature.  That needs programs,
          that use it, to recompile against the new header definition.
        - print servfail info to log as error.
        - added more servfail printout statements, to the iterator.
        - log-servfail: yes prints log lines that say why queries are
          returning SERVFAIL to clients.

   16 August 2018: Wouter
        - Fix warning on compile without threads.
        - Fix contrib/fastrpz.patch.

   15 August 2018: Wouter
        - Fix segfault in auth-zone read and reorder of RRSIGs.

   14 August 2018: Wouter
        - Fix that printout of error for cycle targets is a verbosity 4
          printout and does not wrongly print it is a memory error.
        - Upgraded crosscompile script to include libunbound DLL in the
          zipfile.

   10 August 2018: Wouter
        - Fix #4144: dns64 module caches wrong (negative) information.

   9 August 2018: Wouter
        - unbound-checkconf checks if modules exist and prints if they are
          not compiled in the name of the wrong module.
        - document --enable-subnet in doc/README.
        - Patch for stub-no-cache and forward-no-cache options that disable
          caching for the contents of that stub or forward, for when you
          want immediate changes visible, from Bjoern A. Zeeb.

   7 August 2018: Ralph
        - Make capsforid fallback QNAME minimisation aware.

   7 August 2018: Wouter
        - Fix #4142: unbound.service.in: improvements and fixes.
          Add unit dependency ordering (based on systemd-resolved).
          Add 'CAP_SYS_RESOURCE' to 'CapabilityBoundingSet' (fixes warnings
          about missing privileges during startup). Add 'AF_INET6' to
          'RestrictAddressFamilies' (without it IPV6 can't work). From
          Guido Shanahan.
        - Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
          This limits the number of simultaneous TCP client connections
          from a nominated netblock.
        - make depend, yacc, lex, doc, headers.  And log the limit exceeded
          message only on high verbosity, so as to not spam the logs when
          it is busy.

   6 August 2018: Wouter
        - Fix for #4136: Fix to unconditionally call destroy in daemon.c.

   3 August 2018: George
        - Expose if a query (or a subquery) was ratelimited (not src IP
          ratelimiting) to libunbound under 'ub_result.was_ratelimited'.
          This also introduces a change to 'ub_event_callback_type' in
          libunbound/unbound-event.h.
        - Tidy pylib tests.

   3 August 2018: Wouter
        - Revert previous change for #4136: because it introduces build
          problems.
        - New fix for #4136: This one ignores lex without without
          yylex_destroy.

   1 August 2018: Wouter
        - Fix to remove systemd sockaddr function check, that is not
          always present.  Make socket activation more lenient.  But not
          different when socket activation is not used.
        - iana port list update.

   31 July 2018: Wouter
        - Patches from Jim Hague (Sinodun) for EDNS KeepAlive.
        - Sort out test runs when the build directory isn't the project
          root directory.
        - Add config tcp-idle-timeout (default 30s). This applies to
          client connections only; the timeout on TCP connections upstream
          is unaffected.
        - Error if EDNS Keepalive received over UDP.
        - Add edns-tcp-keepalive and edns-tcp-keepalive timeout options
          and implement option in client responses.
        - Correct and expand manual page entries for keepalive and idle timeout.
        - Implement progressive backoff of TCP idle/keepalive timeout.
        - Fix 'make depend' to work when build dir is not project root.
        - Add delay parameter to streamtcp, -d secs.
          To be used when testing idle timeout.
        - From Wouter: make depend, the dependencies in the patches did not
          apply cleanly.  Also remade yacc and lex.
        - Fix mesh.c incompatible pointer pass.
        - Please doxygen so it passes.
        - Fix #4139: Fix unbound-host leaks memory on ANY.

        - Print error if SSL name verification configured but not available
          in the ssl library.
        - Fix that ratelimit and ip-ratelimit are applied after reload of
          changed config file.
        - Resize ratelimit and ip-ratelimit caches if changed on reload.

   16 July 2018: Wouter
        - Fix qname minimisation NXDOMAIN validation lookup failures causing
          error_supers assertion fails.
        - Squelch can't bind socket errors with Permission denied unless

        - Fix documentation ambiguity for tls-win-cert in tls-upstream and
          forward-tls-upstream docs.
        - iana port update.
