  * Fix for DNSSEC bug in finding most specific key when
    trust anchor proves non-existance of one of the labels
    along the authentication chain other than the non-
    existance of a DS record on a zonecut.
  * Enhancement getdnsapi/stubby#56 & getdnsapi/stubby#130:
    Configurable minimum and maximum TLS versions with
    getdns_context_set_tls_min_version() and
    getdns_context_set_tls_max_version() functions and
    tls_min_version and tls_max_version configuration parameters

      This is configurable with the --with-max-udp-backoff configure
      option.
    Thanks Robert Groenenberg
  * Bugfix: Find zonecut with DS queries (instead of SOA queries).
    Thanks Elmer Lastdrager

    with the tls_curves_list setting in the upstream dict with
    getdns_context_set_upstream_recursive_servers()
  * New tool getdns_server_mon for checking upstream recursive
    resolver's capabilities.
  * Improved handling of opportunistic back-off.  If other transports
    are working, don’t forcibly promote failed upstreams just wait for
    the re-try timer.
  * Hostname authentication with libressl
    Thanks Norbert Copones
  * Security bugfix in response to CVE-2017-15105.  Although getdns was
    not vulnerable for this specific issue, as a precaution code has been
    adapted so that signatures of DNSKEYs, DSs, NSECs and NSEC3s can not
    be wildcard expansions when used with DNSSEC proofs.  Only direct
    queries for those types are allowed to be wildcard expansions.

    memory double linked list detected issue, with serving functionality.
    Thanks maddie and Bruno Pagani

    with the tls_cipher_list setting in the upstream dict with
    getdns_context_set_upstream_recursive_servers()
  * PR #366: Add support for TLS 1.3 and Chacha20-Poly1305
    Thanks Pascal Ernster

    validation.  Thanks Bruno Pagani

* 2017-11-11: Version 1.2.1
  * Handle more I/O error cases.  Also, when an I/O error does occur,
    never stop listening (with servers), and
    never exit (when running the built-in event loop).
  * Bugfix: Tolerate unsigned and unused RRsets in the authority section.
            Fixes DNSSEC with BIND upstream.
  * Bugfix: DNSSEC validation without support records
  * Bugfix: Validation of full recursive DNSKEY lookups
  * Bugfix: Retry to validate full recursion BOGUS replies with zero
    configuration DNSSEC only when DNSSEC was actually requested
  * Bugfix #348: Fix a linking issue in stubby when libbsd is present
    Thanks Remi Gacogne
  * More robust scheduling; Eliminating a segfault with long running

    described in RFC7958.  The URL from which to fetch
    the trust anchor, the verification CA and email
    can be set with the new getdns_context_set_trust_anchor_url(),
    getdns_context_set_trust_anchor_verify_CA() and
    getdns_context_set_trust_anchor_verify_email() functions.
    The default values are to fetch from IANA and to validate
    with the ICANN CA.
  * Update of Stubby with yaml configuration file and
    logging from a certain severity support.
  * Fix tpkg exit status on test failure. Thanks Jim Hague.
  * Refined logging levels for upstream statistics
  * Reuse (best behaving) backed-off TLS upstreams when non are usable.
  * Let TLS upstreams back-off a incremental amount of time.
    Back-off time starts with 1 second and is doubled each failure, but
    will not exceed the time given by getdns_context_set_tls_backoff_time()
  * Make TLS upstream management more resilient to temporary outages
    (like laptop sleeps)

* 2017-09-04: Version 1.1.3
  * Small bugfixes that came out of static analysis
  * No annotations with the output of getdns_query anymore,
    unless -V option is given to increase verbosity

    but does not have it implemented.  Thanks Joel Purra
  * Compile without Stubby by default.  Stubby now has a git repository
    of its own.  The new Stubby repository is added as a submodule.
    Stubby will still be build alongside getdns with the --with-stubby
    configure option.

* 2017-07-03: Version 1.1.2
  * Bugfix for parallel make install
  * Bugfix to trigger event callbacks on socket errors

    from a json like formatted file.  The output of -i (print API
    information) can be used as config file directly.
    Settings may also be given in this format as arguments of
    the getdns_query command directly.
  * DNS server mode for getdns_query.  Enable by providing addresses
    to listen on, either by giving "-z <listen address>" options or by

    TLS verification. GETDNS_AUTHENTICATION_HOSTNAME is replaced by 
    GETDNS_AUTHENTICATION_REQUIRED (but remains available as an alias). 
    Upstreams can now be configured with either a hostname or a SPKI pinset 
    for TLS authentication (or both). If the GETDNS_AUTHENTICATION_REQUIRED
    option is used at least one piece of authentication information must be 
    configured for each upstream, and all the configured authentication 
    information for an upstream must validate.
  * Remove STARTTLS implementation (no change to SPEC)

    (-K) to attach pinsets to getdns_contexts.
    Thanks Daniel Kahn Gillmor
  * Initial support for Windows.  Thanks Gowri Visweswaran
  * add_warning_for_bad_dns extension
  * Try and retry with suffixes giving with getdns_context_set_suffix()
    following directions given by getdns_context_set_append_name()
    getdns_query options to set suffixes and append_name directions:
    '-W' to append suffix always (default)
    '-1' to append suffix only to single label after failure
    '-M' to append suffix only to multi label name after failure
    '-N' to never append a suffix
    '-Z <suffixes>' to set suffixes with the given comma separated list
  * Better help text for getdns_query (printed with the '-h' option)

    When using DNS over TLS, query sizes will be padded to multiples
    of a block size given with:
    getdns_context_set_tls_query_padding_blocksize()
  * An EDNS client subnet private option, that will ask a EDNS client
    subnet aware resolver to not reveal any details about the 
    originating network.  See: draft-ietf-dnsop-edns-client-subnet
    Set with: getdns_context_set_edns_client_subnet_private()
  * The return_call_debugging extension.  The extension will also return
    the transport used on top of the information about the request which
    is described in the API spec.
  * A dnssec_roadblock_avoidance extension.  When set, the library will
    work in stub resolution mode and try to get a by DNSSEC validation
    assessed answer.  On BOGUS answers the library will retry rescursive
    resolution mode.  This is the simplest form of passive roadblock
    detection and avoidance: draft-ietf-dnsop-dnssec-roadblock-avoidance.
    Use the --enable-draft-dnssec-roadblock-avoidance option to configure
    to compile with this extension.

* 2015-10-29: Version 0.5.0
  * Native crypto.  No ldns dependency anymore.

    to dereference nested dicts and lists.
  * Bugfix: DNSSEC code finding zone cut with redirects + pursuing unsigned
    DS answers close to the root.  Thanks Theogene Bucuti!
  * Default port for TLS changed to 853
  * Unofficial extension to the API to allow TLS hostname verification to be
    required for stub mode when using only TLS as a transport. 
    When required a hostname must be supplied in the
    'hostname' field of the upstream_list dict and the TLS cipher suites are
    restricted to the 4 AEAD suites recommended in RFC7525.
