* Added new way to specify QoS settings for publishers and subscriptions. (`#713 <https://github.com/ros2/rclcpp/issues/713>`_)
* Deprecated ``shared_ptr`` and raw pointer versions of ``Publisher<T>::publish()``. (`#709 <https://github.com/ros2/rclcpp/issues/709>`_)
* Implemented API to set callbacks for liveliness and deadline QoS events for publishers and subscriptions. (`#695 <https://github.com/ros2/rclcpp/issues/695>`_)
* Changed the ``IntraProcessManager`` to be capable of storing ``shared_ptr<const T>`` in addition to ``unique_ptr<T>``. (`#690 <https://github.com/ros2/rclcpp/issues/690>`_)
* Added functions that allow you to publish serialized messages and received serialized messages in your subscription callback. (`#388 <https://github.com/ros2/rclcpp/issues/388>`_)
* Added ability to initialize parameter values in a node with an argument to the Node constructor. (`#486 <https://github.com/ros2/rclcpp/issues/486>`_)
* Nodes now autostart the ROS parameter services which let you get, set, and list parameters in a node. (`#478 <https://github.com/ros2/rclcpp/issues/478>`_)
* Fixed a bug that occurred when mixing ``std::shared_ptr`` and ``std::bind``. (`#470 <https://github.com/ros2/rclcpp/issues/470>`_)
* Added ability to pass command line arguments to the Node constructor. (`#461 <https://github.com/ros2/rclcpp/issues/461>`_)
* Changed library export order for static linking. (`#446 <https://github.com/ros2/rclcpp/issues/446>`_)
* Now depends on ``ament_cmake_ros``. (`#444 <https://github.com/ros2/rclcpp/issues/444>`_)
* Updaed code to use logging macros rather than ``fprintf()``. (`#439 <https://github.com/ros2/rclcpp/issues/439>`_)
