This release has features for saving memory and faster notification.
With --enable-packed, 33% memory savings could be had, or something
along that size.  Notification of secondary servers happens in parallel,
and has faster timeouts.  More sockets are used for zone transfers.
This speeds up communication with a larger set of servers.

- xfr-inspect, it is not installed, it prints xfr files from /tmp
  made with 'make xfr-inspect' in the source dir.
- retry timeout between sending notifies dropped from 15 to 3 sec.
- NSD sends 16 notifies simultaneously.
- configure --enable-packed reduces memory usage, at expense of
  unaligned reads.  Saves about 17%.
- Save memory by selectively allocate precompiled nsec3 hashes,
  saves about 16% memory.
- make ip-transparent option work on OpenBSD.
- Save about 2% memory by changing usage count size in name tree.
- Fix #2871: Increase number of sockets for xfrd transfers.

- Fix gcc 7.1.1 warnings.
- Fix writev compile warning on FreeBSD.
- Fix #1446: A corrupted zone file "propagates" to good ones.
- nsd-control zonestatus prints wait time between attempts, for zones
  that are in that waiting time.
- Fix collision printout of nsec3 to print name, hash and reverse.
- Fix #1567: Change crit to err log level for gettimeofday failure.
  Add defines for compile without syslog.

Best regards, Wouter
