Dear All,

We have a release candidate for version 0.5.0 of getdns.

This is mostly a new features release

This release does all crypto operations using OpenSSL directly and has
no longer a dependency on libldns. Note however that libldns is still
used by the unit tests.

Following the October 2015 release of the API specification, this
library release now allows to accesses deeply embeded datastructure
members in getdns_dicts by JSON Pointer RFC 6901. This works both for
both the getter and setter functions.

DNS over TLS now uses the default IANA assigned port number for
domain-s: 853.

This release includes an experimental implementation of upstream
server hostname authentication for TLS connections in stub mode (note
that the default behaviour has not changed compared to the 0.3
release). A new, non-standard function
getdns_context_set_tls_authentication() can be used to set the
authentication to GETDNS_AUTHENTICATION_ which requires that a server
provides a valid certificate (validated using the default CA
repository) and that the hostname specified in the "tls_auth_name"
field of the upstream dict matches that in the certificate. The
authentication setting is only enforced when the transport list
contains only GETDNS_TRANSPORT_TLS and in this case if authentication
fails for all upstreams, queries will fail. If the transport list
contains other clear text transports then opportunistic TLS will be
performed which does not require authentication of the TLS connection.
Examples of usage using the getdns_query tool can be found in the
tests_transports.sh script in the test directory.

Please review this candidate carefully. If no issues arrise the actual
release will follow Thursday the 29th of October 2015.

* 2015-10-??: 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.
    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.
Version: GnuPG v2
