Log Message:
Unbound 1.4.16

Features:

* applied patch to support outgoing-interface with ub_ctx_set_option.

Bug Fixes:

* Fix validation failures (like: validation failure xx: no NSEC3 closest
  encloser from yy for DS zz. while building chain of trust, because of
  a bug in the TTL-fix in 1.4.15, it picked the wrong rdata for an NSEC3.
  Now it does not change rdata, and fixes TTL.
* Fix version-number in libtool to be version-info so it produces
  libunbound.so.2 like it should.
* Fixes for port to OpenIndiana OS with gcc 4.6.
* Fix to write key files completely to a temporary file, and if that
  succeeds, replace the real key file. So failures leave a useful file.

Unbound 1.4.15

Bug Fixes:

* Fix for memory leak (about 20 bytes when a tcp or udp send operation
  towards authority servers failed, takes about 50.000 such failures to
  leak one Mb, such failures are also usually logged).
* Fix to randomize hash function, based on 28c3 congress.
* [bugzilla: 425 ] unbound reports wrong TTL in reply, it reports a TTL
  that would be permissible by the RFCs but it is not the TTL in the cache.
* [bugzilla: 429 ] add ub_version() call to libunbound. API version increase,
  with (binary) backwards compatibility for the previous version.
* Fix bug where canonical_compare of RRSIG did not downcase the signer-name.
  This is mostly harmless because RRSIGs do not have to be sorted in
  canonical order, usually.
* uninitialised variable in reprobe for rtt blocked domains fixed.
* iana portlist updated.
