  - unbound-control auth_zone_transfer _zone_ option starts the probe
    sequence for a master to transfer the zone from and transfers when
    a new zone version is available.
  - num.queries.tls counter for queries over TLS.
  - log port number with err_addr logs.
  - dns64-ignore-aaaa: config option to list domain names for which the
    existing AAAA is ignored and dns64 processing is used on the A
  - Fix #4112: Fix that unbound-anchor -f /etc/resolv.conf will not pass
    if DNSSEC is not enabled.  New option -R allows fallback from
    resolv.conf to direct queries.
  - Note RFC8162 support.  SMIMEA record type can be read in by the
    zone record parser.
  - Patches from Jim Hague (Sinodun) for EDNS KeepAlive.
  - Add config tcp-idle-timeout (default 30s). This applies to
    client connections only; the timeout on TCP connections upstream
    is unaffected.
  - Add edns-tcp-keepalive and edns-tcp-keepalive timeout options
    and implement option in client responses.
  - Add delay parameter to streamtcp, -d secs.
    To be used when testing idle timeout.
  - 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
  - Patch to implement tcp-connection-limit from Jim Hague (Sinodun).
    This limits the number of simultaneous TCP client connections
    from a nominated netblock.
  - Fix #4142: 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.
  - unbound-checkconf checks if modules exist and prints if they are
    not compiled in the name of the wrong module.
  - 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.
  - Upgraded crosscompile script to include libunbound DLL in the
  - 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.
  - log-servfail: yes prints log lines that say why queries are
    returning SERVFAIL to clients.
  - log-local-actions: yes option for unbound.conf that logs all the
    local zone actions, a patch from Saksham Manchanda (Secure64).

  - #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
  - 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.
  - Added serve-expired-ttl and serve-expired-ttl-reset options.

* Thu May 03 2018
  - update to 1.7.1
  - Add --with-libhiredis, unbound support for a new cachedb
    backend that uses a Redis server as the storage.  This
    implementation depends on the hiredis client library
    And unbound should be built with both --enable-cachedb and
    - -with-libhiredis[=PATH] (where $PATH/include/hiredis/hiredis.h
    should exist).  Patch from Jinmei Tatuya (Infoblox).
  - Create additional tls service interfaces by opening them on other
    portnumbers and listing the portnumbers as additional-tls-port: nr.
  - ED448 support.

  - nitpick fixes in example.conf.
  - Fix above stub queries for type NS and useless delegation point.

  - Commented configuration directive dlv-anchor-file: in unbound.conf
    (see bsc#1055060). The DLV key file is deliberately still
    shipped in the package so users could easily re-enable this.
* Wed Apr 04 2018
  - update to 1.7.0
  - auth-zone provides a way to configure RFC7706 from unbound.conf,
    eg. with auth-zone: name: "." for-downstream: no for-upstream: yes
    fallback-enabled: yes and masters or a zonefile with data.
  - Aggressive use of NSEC implementation. Use cached NSEC records to
    generate NXDOMAIN, NODATA and positive wildcard answers.
  - Accept tls-upstream in unbound.conf, the ssl-upstream keyword is
    also recognized and means the same.  Also for tls-port,
    tls-service-key, tls-service-pem, stub-tls-upstream and
  - [dnscrypt] introduce dnscrypt-provider-cert-rotated option,
    from Manu Bretelle.
    This option allows handling multiple cert/key pairs while only
    distributing some of them.
    In order to reliably match a client magic with a given key without
    strong assumption as to how those were generated, we need both key and
    cert. Likewise, in order to know which ES version should be used.
    On the other hand, when rotating a cert, it can be desirable to only
    serve the new cert but still be able to handle clients that are still
    using the old certs's public key.
    The `dnscrypt-provider-cert-rotated` allow to instruct unbound to not
    publish the cert as part of the DNS's provider_name's TXT answer.

    * Added generic EDNS code for registering known EDNS option codes,
      bypassing the cache response stage and uniquifying mesh states. Four
      EDNS option lists were added to module_qstate
      (module_qstate.edns_opts_*) to store EDNS options from/to front/back side.
    * Added two flags to module_qstate (no_cache_lookup, no_cache_store)
      that control the modules' cache interactions.

      functions can be called just before replying with local data or Chaos,
      replying from cache, replying with SERVFAIL, replying with a resolved
      query, sending a query to a nameserver. The functions can inspect the
      available data and maybe change response/query related data (i.e. append
      EDNS options).

    instead introduce a libunbound-devel-mini package which holds the
    shared library and devel files with a minimal build requires.
* Thu Feb 04 2016
  - split off a libunbound package with less buildrequires to
    allow shorter buildcycles when built by gnutls. bsc#964346

* Thu Oct 15 2015
  - update to 1.5.6
    - Default for ssl-port is port 853, the temporary port assignment for
      secure domain name system traffic. If you used to rely on the older
      default of port 443, you have to put a clause in unbound.conf for
      that. The new value is likely going to be the standardised port number
      for this traffic.
    - ANY responses include DNAME records if present, as per Evan Hunt's
      remark in dnsop.

    - Allow certificate chain files to allow for intermediate
      certificates. (thanks Daniel Kahn Gillmor)
    - Enable ECDHE for servers. Where available, use
      SSL_CTX_set_ecdh_auto() for TLS-wrapped server configurations
      to enable ECDHE. Otherwise, manually offer curve p256. Client
      connections should automatically use ECDHE when available.
      (thanks Daniel Kahn Gillmor)
    - Feature --enable-pie option to that builds PIE binary.
      [bugzilla: 699 ]
    - Feature --enable-relro-now option that enables full read-only

      harden-algo-downgrade is turned off.
    - Document in the manual more text about configuring locally
      served zones.

    - Fix that configure script does not detect LibreSSL 2.2.2
      [bugzilla: 694 ]
    - Fix deadlock for local data add and zone add when

  - update to 1.5.4
    - [bugzilla: 644 ] harden-algo-downgrade option, if turned off,
      fixes the reported excessive validation failure when multiple
      algorithms are present. If set to 'no', it allows the weakest
      algorithm to validate the zone.
    - stats reports tcp usage, of incoming-num-tcp buffers.
    - contrib/unbound_smf22.tar.gz: Solaris SMF installation/removal
      scripts. Contributed by Yuri Voinov.
    - Add ip-transparent config option for bind to non-local addresses.
    - Synthesize ANY responses from cache. Does not search exhaustively,
      but MX,A,AAAA,SOA,NS also CNAME.
    - unbound-control list_insecure command shows the negative trust
      anchors currently configured, patch from Jelte Jansen.
    - ratelimit feature, ratelimit: 1000, can be used to turn it on. It
      ratelimits recursion effort per zone. For particular names you can
      configure exceptions in unbound.conf.
    - Ratelimit does not apply to prefetched queries, and
      ratelimit-factor is default 10. Repeated normal queries get resolved
      and with prefetch stay in the cache.
    - unbound-control ratelimit_list lists high rate domains.
    - caps-whitelist in unbound.conf allows whitelist of loadbalancers
      that cannot work with caps-for-id or its fallback.
    - RFC 7553 RR type URI support, is now enabled by default.
    - cache-max-negative-ttl config option, default 3600.
    - Add local-zone type inform_deny, that logs query and drops answer.
    Bug Fixes
    - Unbound exits with a fatal error when the auto-trust-anchor-file
      fails to be writable. This is seconds after startup. You can load a
      readonly auto-trust-anchor-file with trust-anchor-file. The file has
      to be writable to notice the trust anchor change, without it, a trust
      anchor change will be unnoticed and the system will then become
    - DLV is going to be decommissioned. Advice to stop using it, and
      put text in the example configuration and man page to that effect.
    - Patch from Brad Smith that syncs compat/getentropy_linux with
      OpenBSD's version (2015-03-04).
    - 0x20 fallback improved: servfail responses do not count as missing
      comparisons (except if all responses are errors), inability to find
      nameservers does not fail equality comparisons, many nameservers does
      not try to compare more than max-sent-count, parse failures start 0x20
      fallback procedure.
    - store caps_response with best response in case downgrade response
      happens to be the last one.
    - Document that incoming-num-tcp increase is good for large servers.
    - Fix lintian warning in unbound-checkconf man page (from Andreas
    - Updated default keylength in unbound-control-setup to 3k.
    - Fixup compile on cygwin, more portable openssl thread id.
    - Use reallocarray for integer overflow protection, patch submitted
      by Loganaden Velvindron.
    - Fixed to add integer overflow checks on allocation (defense in depth).
    - Fix segfault on user not found at startup (from Maciej Soltysiak).
    - [bugzilla: 657 ] Fix that libunbound(3) recommends deprecated
    - If unknown trust anchor algorithm, and libressl is used, error
      message encourages upgrade of the libressl package.
    - rename ldns subdirectory to sldns to avoid name collision.
    - [bugzilla: 660 ] Fix interface-automatic broken in the presence of
      asymmetric routing.
    - Libunbound skips dos-line-endings from etc/hosts.
    - Fix crash in dnstap: Do not try to log TCP responses after timeout.
    - Fix that get_option for cache-sizes does not print double newline.
    - [bugzilla: 663 ] Fix that ssl handshake fails when using unix
      socket because dh size is too small.
    - [bugzilla: 664 ] libunbound python3 related fixes (from Tomas
      Hozza); Use print_function also for Python2. libunbound examples:
      produce sorted output. libunbound-Python: libldns is not used anymore.
      Fix issue with Python 3 mapping of FILE* using file_py3.i from ldns.
    - Fix leaked dns64prefix configuration string.
    - Removed contrib/unbound_unixsock.diff, because it has been
      integrated, use control-interface: /path in unbound.conf.
    - Change syntax of particular validator error to be easier for
      machine parse, swap rrset and ip adres info so it looks like:
      validation failure < TXT IN>: signature crypto failed
      from 2001:DB8:7:bba4::53 for <* NSEC IN>
    - Fix that unparseable error responses are ratelimited.
    - SOA negative TTL is capped at minimumttl in its rdata section.
    - [bugzilla: 674 ] Do not free pointers given by getenv.
    - [bugzilla: 677 ] Fix CNAME corresponding to a DNAME was checked
      incorrectly and was therefore always synthesized (thanks to Valentin
      Dietrich). And fix DNAME responses from cache that failed internal
      chain test.
    - iana portlist update.

    - Patch from Robert Edmonds fixes hyphens in unbound-anchor man
    - Removed 'increased limit open files' log message that is
      written to console. It is only written on verbosity 4 and

    - unbound-control stats prints num.query.tcpout with number of
      TCP outgoing queries made in the previous statistics interval.
    - Patch from Jeremie Courreges-Anglas to use arc4random_uniform
      if available on the OS, it gets entropy from the OS.
    - Add unbound-control flush_negative that flushed nxdomains,
      nodata, and errors from the cache. For dnssec-trigger and
      NetworkManager, fixes cases where network changes have
      localdata that was already negatively cached from the previous
    - Contrib windows scripts from Yuri Voinov added to src/contrib:
      create_unbound_ad_servers.cmd: enters anti-ad server lists.

    - Patch from Dag-Erling Smorgrav that implements that: unbound
    - dd does not fork in the background and also logs to stderr.
    - DNS64 from Viagenie (BSD Licensed), written by Simon Perrault.

    - [bugzilla: 567] Fix unbound lists if forward zone is secure or
      insecure with +i annotation in output of list_forwards, also
      for list_stubs (for NetworkManager integration). And remove ':'
      from output of stub and forward lists, this is easier to parse.
    - [bugzilla: 554] Fix use unsigned long to print 64bit statistics
      counters on 64bit systems.

    - Fixup out-of-directory compile with
    - Code cleanup patch from Dag-Erling Smorgrav, with compiler
      issue fixes from FreeBSD's copy of Unbound, he notes: Generate at build time so it respects prefix
      and sysconfdir from the configure script.  Also fix the umask
      to match the comment, and the comment to match the umask. Add
      const and static where needed. Use unions instead of playing
      pointer poker. Move declarations that are needed in multiple
      source files into a shared header. Move sldns_bgetc() from
      parse.c to buffer.c where it belongs. Introduce a new header
      file, worker.h, which declares the callbacks that all workers
      must define. Remove those declarations from libworker.h.
      Include the correct headers in the correct places. Fix a few
      dummy callbacks that don't match their prototype. Fix some
      casts. Hide the sbrk madness behind #ifdef HAVE_SBRK. Remove a
      useless printf which breaks reproducible builds. Get rid of
      CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're no longer
      used. Add to the list of generated
      files. The prototype for libworker_event_done_cb() needs to be
      moved from libunbound/libworker.h to libunbound/worker.h.
