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) * Enable TCP Fast Open when possible. Add OSX support for TFO. * Rename return_call_debugging to return_call_reporting * Bugfix: configure problem with getdns-0.5.1 on OpenBSD Thanks Claus Assmann. * pkg-config support.

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 ' to set suffixes with the given comma separated list * Better help text for getdns_query (printed with the '-h' option) * Setting the +specify_class extension with getdns_query * Return NOT_IMPLEMENTED for not implemented namespaces, and the not implemented getdns_context_set_follow_redirects() function. * 2015-11-18: Version 0.5.1 * Bugfix: growing upstreams arrow. * Bugfix: Segfault on timeout in specific conditions * Bugfix: install getdns_extra.h from build location * Bugfix: Don't let cookies overwrite existing EDNS0 options * Don't link libdl * The EDNS(0) Padding Option (draft-mayrhofer-edns0-padding).

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. (ldns still necessary to be able to run tests though) * JSON pointer arguments to getdns_dict_get_* and getdns_dict_set_* 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.

Thanks Paul Wouters. * Added new transport list options in API. The option is now an ordered list of GETDNS_TRANSPORT_UDP, GETDNS_TRANSPORT_TCP, GETDNS_TRANSPORT_TLS, GETDNS_TRANSPORT_STARTTLS. * Added new context setting for idle_timeout * CSYNC RR type * EDNS0 COOKIE option code set to 10 * dnssec_return_validation_chain for negative and insecure responses. * dnssec_return_validation_chain return a single RRSIG on each RRSET (whenever possible) * getdns_validate_dnssec() accept replies from the replies_tree * getdns_validate_dnssec() asses negative and insecure responses. * Native stub dnssec validation * Implemented getdns_context_set_dnssec_trust_anchors() * Switch freely between stub and recursive mode * getdns_query -k shows default trust anchors * functions and defines to get library and API versions in string and numeric values: getdns_get_version(), getdns_get_version_number(), getdns_get_api_version() and getdns_get_api_version_number() * 2015-05-21: Version 0.2.0 * Fix libversion numbering: Thanks Daniel Kahn Gillmor * run_once method for the libevent extension * autoreconf -fi on FreeBSD always, because of newer libtool version suitable for FreeBSD installs too.

Thanks Ondřej Surý * Fix: Include m4 dir in distribution tarball * Fix: Link build requirements in tests too. Thanks Ondřej Surý * Fix: Remove executable flags on source files. Thanks Paul Wouters * Fix: Return "just_address_answers" only when queried for addresses * Eliminate ldns intermediate wireformat parsing * The CSYNC RR type * Fix: canonical_name in response dict returns the canonical name found after following all CNAMEs * Implementation of the section 6 and 7 version of draft-ietf-dnsop-cookies-01.txt for stub resolution. Enable with the --enable-draft-edns-cookies option to configure.

This results in AAAA being the first in the just_address_answers sections of the response dict. * New context update callback function to also return a user given argument along with the context and which item was changed. Thanks Scott Hollenbeck. * Demotivate use of getdns_strerror and expose getdns_get_errorstr_by_id. Thanks Scott Hollenbeck. * A getter for context update callback, to allow for chaining update callbacks. * 2015-01-16: Version 0.1.6 * Fix: linking against libev on FreeBSD * Fix: Let configure report problem on FreeBSD when configuring with libevent and libunbound <= 1.4.22 is not compiled with libevent. * Fix: Build on Mac OS-X * Fix: Lintian errors in manpages * Better libcheck detection * Better portability with UNIX systems * 2014-10-31: Version 0.1.5 * Unit tests for transport settings * Fix: adhere to set maximum UDP payload size * API change: when no maximum UDP payload size is set, outgoing values will adhere to the suggestions in RFC 6891 and may follow a scheme that uses multiple values to maximize receptivity. * Stub mode use 1232 maximum UDP payload size when connecting to an IPv6 upstreams and 1432 with an IPv4 upstream. * Evaluate namespaces (or not) on a per query basis * GETDNS_NAMESPACE_LOCALNAMES namespace now gives just_address_answers only and does not mimic a DNS packet answer anymore * The add_opt_parameters extension * IPv6 scope_id support with link-local addresses.
