- The Event Receiver is updated to take in an additional input -> attribute_dictionary, to specify what attributes to subscribe to. This change is backwards compatible. Bugs in the run method of Event Receiver, the handler methods in TmcLeafNodeComponentManager, and the starting of event receiver instance from the same class are fixed. - A bug in the tmc_command class in the track_transitions method is fixed, where an exception could be raised from the caught exception in thread. - track_transitions method in tmc_command class is renamed to track_and_update_command_status and refactored to have code further modular.
