Dear all,

We have a first release candidate for the upcoming 1.2.2 bugfix release
of getdns.

Recently Stubby has seen increased interest. Already after the release
of the Windows installer, but even more so after the introduction of
Quad9 and the description of how to use DNS-over-TLS with Stubby by Alex
Band and Stéphane Borzmeyer.

The increased install base has generated excellent feedback and has also
revealed some bugs. This release has those bugs fixed, and also contains
a few more configuration options to be able to adapt to more diverse

The bugs fixed with this release are:

  * A segfault with the native DNSSEC validation code when DS and DNSKEY
    queries timed out,

  * A non RFC compliant edns_client_subnet_private option that caused
    some upstream EDNS Client Subnet implementations (i.e. Unbound's) to
    return FORMERR, and

  * Doing the meta queries for Zero configuration DNSSEC with the
    resolvers from /etc/resolv.conf, which cause Stubby to query itself
    for this, effectively breaking the possibility to fetch the root
    trust-anchors and bootstrap DNSSEC.

Besides these fixes, this release allows to configure a getdns_context
to be initialized with resolv.conf and hosts at alternative locations,
with the getdns_context_set_resolvconf() and getdns_context_set_hosts()
functions. Also a specific location for the CA store, for authenticating
DNS-over-TLS upstreams, can be specified with the
getdns_context_set_CApath() and getdns_context_set_CAfile() functions.

The getdns_context_get_api_information() function exposes more
getdns_context settings, amongst which:

  * The default settings for extensions,

  * The paths for files that were used to initialize a getdns_context
    (resolv.conf, hosts and trust anchors), and

  * More information about the version, configuration and capabilities
    of the OpenSSL library in use.

This release candidate includes a candidate for a 0.2.0 release of
Stubby. The most prominent bugfix therein is to not do DNSSEC validation
for queries with the CD bit set, when DNSSEC validation was not
configured in the first place. This bug caused decreased performance for
configurations with an unbound forwarding to Stubby.

The Stubby release candidate also includes some additional auxiliary
functionality which is used by the macOS prototype GUI that was just
released: https://dnsprivacy.org/wiki/display/DP/Stubby+GUI+for+macOS

Please review this release candidate carefully, if all is well, the
actual release will follow Thursday the 21th of December.
