Upgrade Notes: https://sourceforge.net/p/metpx/sarracenia/ci/master/tree/doc/UPGRADING.rst

The major focus of the last few weeks has been improving reliability.
Enhanced reliability should come from three main features:

  -- timeouts: all remote operations now have associated timeouts, and
then attempt to re-connect.
  -- pulse: brokers now have a separate queue to keep idle connections
alive transparently using a pulse message sent periodically.
  -- retry_queue: instead of attempting to send X times (where X is
set by "attempts"), the transfer is set aside to a .retry file.
     This automates use of the save/restore logic, so no analyst
intervention is needed. When there are no messages to send, the
subscriber or sender will pick a message from the retry queue and try
to send it. So the senders should be able to transparently recover
from even prolonged outages.  The old behaviour can be restored via
*retry off* setting in the configuration file.


There is one change in interpretation of configuration files compared
to previous versions:

When an sr_subscribe or an sr_sender has no accept/reject clauses,
then previous versions would send everything. The new version sends
nothing. To have it send everything, as before, append to the config
file:

accept_unmatch

Aside from the above, there are also several bugfixes made since 11a3
(SENDER=, and "Sends:" in particular.)
