20180613
	djbdnscurve6 done (v24).
	Includes curvedns.c and requiring qlibs and NACL.

20180614
	djbdnscurve6 documentation and man pages finished (v25).
	slashpackage installation working.
20180618

	install.c uses now errmsg instead of sys_err (v27).
20180620
	changed FALLBACK to UZ5FALLBACK while default in source is 0; 
	but UZ5FALLBACK=2 in dnscache-conf.
	Working on BSD, Linux, and OmniOS; RasPi using Sodium as NACL lib
	needs still some tweaking (v28).
20180622
	axfrdns + axfr-get working; added axfrdns-conf.8 man page.
	added ./scripts directory including dnscache-log.pl + axfr-get.sh (v29).

	New logmsg calls instead of errmsg (v32).
20180810
	final cleanup & done (v33).
20190313
	added pseudo IP address ':0' for servers to allow simultaneous binding

	Quadratic lookup scheme for dns_transmit.c (tx. Joseph Tam).
	Fixed missing IP address for client rejection in log (tx. Bob Dodds).
	fehQlibs-10 required (v34).
20190609
	fixed bug in tinydns-data with false translatation of IPv6|v4 addreses 
	for MX records. fixed bug in dnsip abending while evaluating IPv6 addresses.
  fixed alignment bug in dd.c for dd6 (tx vise). 
	fixed bug in dns_nd.c for IPv6; dnsfilter is working now for IPv4 and IPv6 (tx vise).
  dns_ip, dns_mx, dns_txt, and dns_name return now number of answers given (fehQlibs-12).
  libsodium compatibility checked and verified (v35).
20190612
	fixed  CVE-2009-0858 in response.c (tx. Martin).
