Dear All,

We have special RIPE71 release, version 0.5.1 of getdns.

This release contains all contributions added during the hackathon
helt at the IETF94 in Yokahama; carefully reviewed and polished.

The included contributions are:

* EDNS(0) padding option
	With this option, the query size will be padded to be a
	multiple of a block size when queried over GETDNS_TRANSPORT_TLS
	transport, to eliminate guessing the query by analyzing query
	sizes. The block size can be set with
	getdns_context_set_tls_query_padding_blocksize() function.

* An EDNS client subnet private option
	With this option EDNS client subnet aware upstreams are asked
	to not reveal the originating network of the query.

* The return_call_debugging extensions
	This extension was already in the API, but had not been
	implemented yet. It returns "meta" information about a query in
	the response dict (under the name "call_debugging". On top of
	the returned information which was already described in the API
	spec, this version also returns information about the transport
	eventually used to perform the query, and (if applicable)
	whether authentication succeeded.

* 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 recursive resolution mode. This is the
	simplest form of passive roadblock detection and avoidance. For
	a very extensive overview of the types of roadblock, see: draft-
	ietf-dnsop-dnssec-roadblock-avoidance. Use the --enable-draft-
	dnssec-roadblock-avoidance option to configure to compile with
	this extension.

Besides these additions contains a few bugfixes too. For an complete
overview see the ChangeLog.

ChangeLog
=========
* 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).
    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.
