 * Adds support for developing `asyncio` applications with `python-can` more easily. This can be useful
   when implementing protocols that handles simultaneous connections to many nodes since you can write
   synchronous looking code without handling multiple threads and locking mechanisms. #388

+* New can viewer terminal application. (`python -m can.viewer`) #390
 * More formally adds task management responsibility to the `Bus`. By default tasks created with
   `bus.send_periodic` will have a reference held by the bus - this means in many cases the user
   doesn't need to keep the task in scope for their periodic messages to continue being sent. If

   something like `fp`, `log_file` or `output_file`. Changed the name of the first parameter of the
   read/writer constructors from `filename` to `file`.
