Features

o Builtin root hints contain AAAA for I.ROOT-SERVERS.NET.
o unbound.h has extern "C" statement for easier include in c++.
o added feature to print configure date, target and options with -h.
o added feature to print event backend system details with -h.
o (ports and works on Minix 3.1.7). On Minix, add /usr/gnu/bin to
PATH, use ./configure AR=/usr/gnu/bin/gar and gmake.
o GOST enabled if SSL is recent and ldns has GOST enabled too.

Bug Fixes

o Fix TCPreply on systems with no writev, if just 1 byte could be
sent.
o Fix to use one pointer less for iterator query state
store_parent_NS.
o Max referral count from 30 to 130, because 128 one character domains
is valid DNS.
o added documentation for the histogram printout to syslog.
o Fix assertion failure reported by Kai Storbeck from XS4ALL, the
assertion was wrong.
o updated ldns tarball.
o iana portlist updated.
o Unbound reports libev or libevent correctly in logs in verbose
mode.
o Fix handling of corner case reply from lame server, follows
rfc2308. It could lead to a nodata reply getting into the cache if
the search for a non-lame server turned up other misconfigured
servers.
o Fix jostle list bug found by Vince (luoce at cnnic), it caused the
qps in overload situations to be about 5 qps for the class of
shortly serviced queries. The capacity of the resolver is then about
(numqueriesperthread / 2) / (average time for such long queries) qps
for long queries. And about (numqueriesperthread / 2)/(jostletimeout
in whole seconds) qps for short queries, per thread.
o Fix the max number of reply-address count to be applied for
duplicate queries, and not for new query list entries. This raises
the memory usage to a max of (16+1)*numqueriesperthread reply
addresses.
o Fix RFC4035 compliance with 2.2 statement that the DNSKEY at apex
must be signed with all algorithms from the DS rrset at the
parent. This is now checked and becomes bogus if not.
o Fix validation of qtype DNSKEY when a key-cache entry exists but no
rr-cache entry is used (it expired or prefetch), it then goes back
up to the DS or trust-anchor to validate the DNSKEY.
o log if a server is skipped because it is on the donotquery list, at
verbosity 4, to enable diagnosis why no queries to 127.0.0.1.
o failure to chown the pidfile is not fatal any more.
o Neat function prototypes, unshadowed local declarations.
o Fix integer underflow in prefetch ttl creation from cache. This
fixes a potential negative prefetch ttl.
o Changed the defaults for num-queries-per-thread/outgoing-range. For
builtin-select: 512/960, for libevent 1024/4096 and for windows
24/48 (because of win api). This makes the ratio this way to improve
resilience under heavy load. For high performance, use libevent and
possibly higher numbers.
