- Update to version 2.1.0
* Added full JSON formatting for all protocols and message types.
This is supported on all output types - file, udp and zmq.
Together with multiple outputs feature that was introduced in
version 2.0.0 this enables arbitrarily flexible arrangements,
like logging to a file as text, logging to another file as JSON
and sending JSON across the network using UDP and/or ZMQ. When
collecting data from multiple receivers, --station-id option
may be used to assign unique names to receivers in order to
discriminate input from each one.
* Removed a few duplicate routines that have their counterparts
in libacars.
