==================
- Added an option, ``start-test-program`` to supply a test command to
test whether the program managed by zdaemon is up and operational,
rather than just running. When starting a program, the start
command doesn't return until the test passes. You could, for
example, use this to wait until a web server is actually accepting
connections.
- Added a ``start-timeout`` option to error if a program takes too long to
start. This is especially useful in combination with the
``start-test-program`` option.
- Added an option, stop-timeout, to control how long to wait
for a graceful shutdown.
Previously, this was controlled by backoff-limit, which didn't make
much sense.
- Several undocumented, untested, and presumably unused features were removed.
