+	  Generate unbound-control-setup.sh at build time so it respects
+	  prefix and sysconfdir from the configure script.  Also fix the
+	  umask to match the comment, and the comment to match the umask.
+	  Add const and static where needed.  Use unions instead of
+	  playing pointer poker.  Move declarations that are needed in
+	  multiple source files into a shared header.  Move sldns_bgetc()
+	  from parse.c to buffer.c where it belongs.  Introduce a new
+	  header file, worker.h, which declares the callbacks that
+	  all workers must define.  Remove those declarations from
+	  libworker.h.	Include the correct headers in the correct places.
+	  Fix a few dummy callbacks that don't match their prototype.
+	  Fix some casts.  Hide the sbrk madness behind #ifdef HAVE_SBRK.
+	  Remove a useless printf which breaks reproducible builds.
+	  Get rid of CONFIGURE_{TARGET,DATE,BUILD_WITH} now that they're
+	  no longer used.  Add unbound-control-setup.sh to the list of
+	  generated files.  The prototype for libworker_event_done_cb()
+	  needs to be moved from libunbound/libworker.h to
+	  libunbound/worker.h.

+20 May 2014: Wouter
+	- Feature, unblock-lan-zones: yesno that you can use to make unbound
+	  perform 10.0.0.0/8 and other reverse lookups normally, for use if
+	  unbound is running service for localhost on localhost.
+
+16 May 2014: Wouter
+	- Updated create_unbound_ad_servers and unbound_cache scripts from
+	  Yuri Voinov in the source/contrib directory. Added
+	  warmup.cmd (and .sh): warm up the DNS cache with your MRU domains.
+
+9 May 2014: Wouter
+	- Implement draft-ietf-dnsop-rfc6598-rfc6303-01.
+	- iana portlist updated.
+
+8 May 2014: Wouter

+	  unbound_cache.cmd: saves and loads the cache.
+	- Added unbound-control-setup.cmd from Yuri Voinov to the windows
+	  unbound distribution set.  It requires openssl installed in %PATH%.

+	- Change MAX_SENT_COUNT from 16 to 32 to resolve some cases easier.
+
+5 May 2014: Wouter
+	- More #567: remove : from output of stub and forward lists, this is
+	  easier to parse.
+
+29 April 2014: Wouter
+	- iana portlist updated.
+	- Add unbound-control flush_negative that flushed nxdomains, nodata,
+	  and errors from the cache.  For dnssec-trigger and NetworkManager,
+	  fixes cases where network changes have localdata that was already
+	  negatively cached from the previous network.
+
+23 April 2014: Wouter
+	- Patch from Jeremie Courreges-Anglas to use arc4random_uniform
+	  if available on the OS, it gets entropy from the OS.
+
+15 April 2014: Wouter
+	- Fix compile with libevent2 on FreeBSD.
+
+11 April 2014: Wouter
+	- Fix #502: explain that do-ip6 disable does not stop AAAA lookups,
+	  but it stops the use of the ipv6 transport layer for DNS traffic.
+	- iana portlist updated.
+
+10 April 2014: Wouter
+	- iana portlist updated.
+	- Patch from Hannes Frederic Sowa for Linux 3.15 fragmentation
+	  option for DNS fragmentation defense.
+	- Document that dump_requestlist only prints queries from thread 0.
+	- unbound-control stats prints num.query.tcpout with number of TCP
+	  outgoing queries made in the previous statistics interval.
+	- Fix #567: unbound lists if forward zone is secure or insecure with
+	  +i annotation in output of list_forwards, also for list_stubs
+	  (for NetworkManager integration.)
+	- Fix #554: use unsigned long to print 64bit statistics counters on
+	  64bit systems.
+	- Fix #558: failed prefetch lookup does not remove cached response
+	  but delays next prefetch (in lieu of caching a SERVFAIL).
+	- Fix #545: improved logging, the ip address of the error is printed
+	  on the same log-line as the error.

+8 April 2014: Wouter
+	- Fix #574: make test fails on Ubuntu 14.04.  Disabled remote-control
+	  in testbound scripts.
+	- iana portlist updated.
+
+7 April 2014: Wouter
+	- C.ROOT-SERVERS.NET has an IPv6 address, and we updated the root

+The DNS64 code was written by Viagenie, 2009, by Simon Perrault as part
+of the Ecdysis project.  The code is copyright by them, and has the BSD
+license (see the dns64/dns64.c file).
+
+To enable DNS64 functionality in Unbound, two directives in unbound.conf must
+be edited:
+
+1. The "module-config" directive must start with "dns64". For example:
+
+    module-config: "dns64 validator iterator"
+
+If you're not using DNSSEC then you may remove "validator".
+
+2. The "dns64-prefix" directive indicates your DNS64 prefix. For example:
+
+    dns64-prefix: 64:FF9B::/96
+
+The prefix must be a /96 or shorter.
+
+To test that things are working right, perform a query against Unbound for a
+domain name for which no AAAA record exists. You should see a AAAA record in
+the answer section. The corresponding IPv6 address will be inside the DNS64
+prefix. For example:
+
+    $ unbound -c unbound.conf
+    $ dig @localhost jazz-v4.viagenie.ca aaaa
+    [...]
+    ;; ANSWER SECTION:
+    jazz-v4.viagenie.ca.        86400   IN      AAAA    64:ff9b::ce7b:1f02
