+Version 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
+
+General fixes, cleanup and docs changes: (#347, #348, #367, #368, #370, #371, #373, #420, #417, #419, #432)
