+
+### Upgrade Notes
+
+RosConnection 2.0: maintain a single constant connection from Unity to the Endpoint. This is more efficient than opening one connection per message, and it eliminates a whole bunch of user issues caused by ROS being unable to connect to Unity due to firewalls, proxies, etc.
+
+### Known Issues
