[getdns-api] getdns-1.5.2 and stubby-0.2.6 released

[Willem Toorop]

Dear all,

I am pleased to announce the new GnuTLS, bugfix and maintenance release,
version 1.5.2 of getdns.

This release has experimental support for GnuTLS >= 3.5.0 as replacement
for OpenSSL. To enabled, use the --with-gnutls option at configure time.
Note that getdns needs the gnutls-dane library too (which is used for
SPKI authentication of DNS-over-TLS upstreams). DNSSEC validation will
use the cryptographic functions from libnettle (the cryptographic
library also used by GnuTLS).

When build with GnuTLS, getdns will still be linked with libcrypto (from
OpenSSL) for S/MIME verification of the root-anchors.xml file with Zero
configuration DNSSEC. It is our intention to replace that with something
more GnuTLS native at some point in the future too, so that getdns can
do without OpenSSL altogether.


Maintenance work included bringing TCP Fast Open up to par with current
practice. This means that at least on Linux 4.11+, getdns can connect
TFO with TLS.

The most prominent bugfix is for DNSSEC scheduling which in some
circumstances wrongly failed with insecure delegations of more than one
label.

A few more issues are resolved with this release. For a complete
overview see the ChangeLog below.


This release has the 0.2.6 release of Stubby included, with updates to
documentation and fixes for the Windows build.
