   - An extra option has been added to the `SubscriberOptions` class allowing the ability to ignore messages when publisher
   and subscriber share the same node. This feature was particularly interesting to avoid loops in the `ros_gz` bridge.

     - Gazebo Ionic allows to request one-way service requests directly from the command line. In prior Gazebo versions, users
     had to specify `--reptype gz.msgs.Empty ` to simulate one-way service requests.
     - The synchronous service requests have now a default timeout, reducing the amount of typing from the CLI.

+- Gazebo camera tracking.
+
+Control tracking, following and see current tracking status from the gui as well as through gz topics. See [gz-gui#619](https://github.com/gazebosim/gz-gui/pull/619), [gz-msgs#440](https://github.com/gazebosim/gz-msgs/pull/440), and [gz-sim#2402](https://github.com/gazebosim/gz-sim/pull/2402).
+
+
+- Change materials dynamically.
+
+Can now make opaque objects translucent, simulate LEDs or other lighting by setting emissivity when source turned on or off from a `gz-transport` message or over `ros-gz` bridge. See [gz-msgs#414](https://github.com/gazebosim/gz-msgs/pull/414), [gz-msgs#415](https://github.com/gazebosim/gz-msgs/pull/415), [gz-msgs#416](https://github.com/gazebosim/gz-msgs/pull/416), [ros_gz#486](https://github.com/gazebosim/ros_gz/pull/486), and [gz-sim#2286](https://github.com/gazebosim/gz-sim/pull/2286).

+
+- Add new primitive geometry for cones.
+
+Create a parametric cone primitive from the gui or in sdf. Useful for sensor visualization, nosecones, and much more.
