- OnData() channel data handler. - ConditionalRun() for devices without incoming data. - Header file with common main(), to be extended with getDevice/addCustomOptions. - Update examples (MQ/Tutorial3) to use the new API and config. - NewSimpleMessage() for simpler creation of small messages (additional copy). - Replace SetProperty/GetProperty with fConfig access. - Runtime configurable channel names for common devices. - Configurable logging interval per channel. - FairMQMultiplier for distributing same data to multiple outputs. - Cleanup state machine messages. - Cmd option to toggle signal handling. - Simpler API for send/receive timeouts. - Enable --log-to-file. - Fix coverity issues, warnings. - Various code cleanup and minor tweaks.
