Hi all,

I have just tagged the spiped-1.6.0 source tree and uploaded the release
tarball to the http://www.tarsnap.com/spiped.html .  The SHA256 hash of
the release tarball is
  e6f7f8f912172c3ad55638af8346ae7c4ecaa92aed6d3fb60f2bda4359cba1e4

Significant changes since 1.5.0:
* The limit of 500 connections to the spiped -n flag has been removed.
* spiped now performs a graceful shutdown on SIGTERM.
* The -k option now accepts "-" as a synonym for standard input.
* A new -v option prints the version number of spipe and spiped.

There are also a variety of less visible changes: Performance improvements in
the SHA256 routines, a workaround for a docker signal-handling bug, minor bug
and compiler warning fixes, the addition of a test suite, and some minor code
reorganization.
