 This is a ROS 2 package for integrating the `ros2_control` controller architecture with the [Gazebo Classic](https://classic.gazebosim.org/) simulator.
 
+> Gazebo Classic goes end-of-life in January of 2025. We strongly recommend all users migrate from Gazebo Classic (numbered releases) to modern Gazebo (formerly known as Ignition 3, lettered releases) before January 2025.
+>
+> Furthermore, Gazebo Classic is not released to Ubuntu Noble. As a consequence, gazebo_ros2_control won't be released for Jazzy and Rolling anymore.

 This package provides a Gazebo plugin which instantiates a `ros2_control` controller manager and connects it to a Gazebo model.
