With the upcoming release of ROS 2 Lyrical Luth in May 2026, Fast DDS will continue serving as the default middleware implementation for ROS 2.

For more than 11 years, Fast DDS has accompanied the ROS 2 ecosystem through every distribution, continuously evolving together with the community to provide scalable, reliable, and high-performance communications.

At eProsima, we are extremely proud to continue contributing to the ROS ecosystem and to support the growing adoption of ROS 2 in robotics, industrial automation, autonomous systems, defense, and many other domains.

Lyrical Luth also brings interesting communication-related improvements, including Native Buffers support in the Fast DDS RMW implementation, opening the door to more efficient accelerated-memory and GPU-oriented transport workflows.

We would like to thank the entire ROS community, Open Robotics, and all contributors involved in making ROS 2 stronger with every release.

Looking forward to Lyrical Luth.

I remember the release of ROS 2 Galactic - the first thing after installation was setting up global environment variables for Fast DDS (not doing this led to some interesting adventures with network administrators :winking_face_with_tongue:).
