3.1.0

packages and was replaced with v3.1.1 after an installation
but was discovered.

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. (`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
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` to allow the Bus base class to manage tasks. 426
* writing to closed writers is not supported any more (it was supported only for some)
* 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`.


Other notable changes
---------------------

* can.Message class updated 413
- Addition of a `Message.equals` method.
- Deprecate id_type in favor of is_extended_id
- Initializer parameter extended_id deprecated 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](https://docs.python.org/3/glossary.html#term-file-like-object) and
[path-like](https://docs.python.org/3/glossary.html#term-path-like-object) 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
- the method `Listener.on_message_received()` is now abstract (using `abc.abstractmethod`)
* 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
