 - **Query primitives**. These simple, GameObject-less shapes allow for collision detection without requiring simulation (i.e., without calling Physics.Simulate). This feature will allow users to initialize objects in feasible locations, and can also be used for motion planning.
 
 ## [**New!**] ROS 2

 In the URDF Importer we have added the functionality to instantiate a robot from URDF into a Unity scene with [Articulation Body](https://docs.unity3d.com/2020.2/Documentation/Manual/class-ArticulationBody.html) components on their corresponding joints.
 
-Aside from facilitating communication with the TCP Endpoint, the TCP Connector contains the `MessageGeneration` code from ROS#. We added the extra functionality that when generating a C# class from a ROS message, functions are also generated that will serialize and deserialize the messages as ROS would internally.
+Aside from facilitating communication with the TCP Endpoint, the TCP Connector contains an adapted version of the `MessageGeneration` code from ROS#. However, unlike ROS# our messages are transmitted in ROS's own serialization format, eliminating the JSON encoding/decoding step for some significant performance improvements.
 
 You can find more details about the differences between our implementation and ROS#, along with some of their future plans, in the [ROS# project](https://github.com/siemens/ros-sharp/wiki/Ext_RosSharp_RoboticsHub#differences-between-unity-robotics-hub-and-ros).
