On Monday, April 4th we’ll start a feature freeze for the [ROS 2 Base packages](https://www.ros.org/reps/rep-2001.html#id23) for the Humble upcoming Humble release on May 23rd.

Once this freeze goes into effect, we will no longer accept additional features to packages in the ROS 2 Base packages, which includes `rcl`, `rclcpp`, `rclpy`, `rosbag2`, `ros2cli`, and `geometry2`. You can see the entire list of included packages here: [REP 2001 -- ROS 2 Variants (ROS.org)](https://www.ros.org/reps/rep-2001.html#id23). Keep in mind the ROS Base packages includes all of the [ROS Core packages](https://www.ros.org/reps/rep-2001.html#id22). **Bug fixes will still be accepted after the freeze date.**

You can find more info on the Humble release timeline here: [Humble Hawksbill (humble) — ROS 2 Documentation: Rolling documentation](https://docs.ros.org/en/rolling/Releases/Release-Humble-Hawksbill.html#release-timeline).
