As of today, the RMWs will be feature frozen in preparation for the upcoming Humble release on May 23rd. This means that we’ll no longer be accepting additional features to the RMWs, which includes [`rmw_fastrtps`](https://github.com/ros2/rmw_fastrtps.git), [`rmw_cyclonedds`](https://github.com/ros2/rmw_cyclonedds.git), [`rmw_connextdds`](https://github.com/ros2/rmw_connextdds.git); as well as their vendor packages, [`Fast-DDS`](https://github.com/eProsima/Fast-DDS), [`Fast-CDR`](https://github.com/eProsima/Fast-CDR), [`cyclonedds`](https://github.com/eclipse-cyclonedds/cyclonedds), and [`iceoryx`](https://github.com/eclipse/iceoryx). **We’ll still accept bug fixes to the RMWs.**

One thing to note is that we’ll be accepting general features in the [ROS 2 base packages](https://www.ros.org/reps/rep-2001.html#id23) until April 4th, when we’ll do a general feature freeze.
