3.0.0

Major features

• 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. #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
  this behavior isn't desired pass store_task=False to the send_periodic method. Stop all tasks
  by calling the bus's new stop_all_periodic_tasks method. #412

Breaking changes

• Interfaces should no longer override send_periodic and instead implement
  _send_periodic_internal #426
• writing to closed writers is not supported any more (it was supported only for some)
• the method Listener.on_message_received() is now abstract (using @abc.abstractmethod)
• the file in the reader/writer is now always stored in the attribute uniformly called file, and not in
  something like fp, log_file or output_file. Changed the name of the first parameter of the
  read/writer constructors from filename to file.

Backend Specific Changes

3rd party interfaces

• Deprecated python_can.interface entry point instead use can.interface. #389

neovi

• Added support for CAN-FD #408
• Fix issues checking if bus is open. #381
• Adding multiple channels support. #415

nican

• implements reset instead of custom flush_tx_buffer. #364

pcan

• now supported on OSX. #365

serial

• Removed TextIOWrapper from serial. #383
• switch to serial_for_url enabling using remote ports via loop://, ``socket://andrfc2217://` URLs. #393
• hardware handshake using rtscts kwarg #402

socketcan

• socketcan tasks now reuse a bcm socket
• socketcan bugfix to receive error frames #384

vector

• Vector interface now implements _detect_available_configs. #362
• Added support to select device by serial number. #387

Other notable changes

• can.Message class updated #413
  • Addition of a Message.equals method.
  • Deprecate id_type in favor of is_extended_id
  • documentation, testing and example updates
  • Addition of support for various builtins: repr, slots, copy
• IO module updates to bring consistency to the different CAN message writers and readers. #348
  • context manager support for all readers and writers
  • they share a common super class called BaseIOHandler
  • all file handles can now be closed with the stop() method
  • the table name in SqliteReader/SqliteWriter can be adjusted
  • append mode added in CSVWriter and CanutilsLogWriter
  • file-like and
    path-like objects can now be passed to
    the readers and writers (except to the Sqlite handlers)
  • add a __ne__() method to the Message class (this was required by the tests)
  • added a stop() method for BufferedReader
  • SqliteWriter: this now guarantees that all messages are being written, exposes some previously internal metrics
    and only buffers messages up to a certain limit before writing/committing to the database.
  • the unused header_line attribute from CSVReader has been removed
  • privatized some attributes that are only to be used internally in the classes
• Start testing against Python 3.7 #380
• All scripts have been moved into can/scripts. #370, #406
• Added support for additional sections to the config #338
• Code coverage reports added. #346, #374
• Bug fix to thread safe bus. #397
