 * [For versions >= `v1.4.0`] All supported ROS versions (melodic/noetic/humble) now work on a completely persistent filesystem to save apt, library and other installations + all other user-defined changes on the container. Additionally, this version also supports audio, enabling users to play sounds through the `rosez` containers.
 * [For versions >= `v1.5.0`] The `sc` or `skip-compilation` flag is now supported, which completely bypasses rosdep and catkin/colcon builds for faster startup.
 * [For versions >= `v1.6.0`] A ROS2 Foxy version is now available (with the `ros2ezf` command). Its image comes with built-in `ros1_bridge` support for *ez* ROS1-ROS2 integration.
+* [For versions >= `v1.6.1`] A deletion script has been included inside the `internal/deeper/` folder. It takes the version-to-delete as an argument. For example, `bash delete_version.bash ros2ezf` deletes the Foxy version for rosez.
 ## Tested platforms
 * EndeavourOS
 * Fedora 35
