We’re happy to announce the release of `rclrs` v0.8.0!

Continuing our proud tradition of Conference-Driven Development (CDD), this release arrives just in time for [ROSCon Global 2026 in Toronto](https://roscon.ros.org/2026/).

If you are at ROSCon, do not miss Michael Grey’s talk on composable actions concurrency with rclrs.

What’s New

### **ROS 2 Lyrical Support**

`rclrs` now supports ROS 2 Lyrical Luth. Bindings have been regenerated for Humble, Jazzy, Kilted, Lyrical, and Rolling.

### **ros-env Message Access**

ROS message packages are now accessed through `ros-env`. This keeps `rclrs`, applications, and generated messages on the same message definitions.

Applications using generated messages should import them with:

`use ros_env::*;`

### **Actions and Parameters**

- `ActionClientState` now exposes `server_is_available`.
- Action APIs received corrections and action-server tasks no longer require Sync.
- Parameter callbacks are now supported.

### **Topic Endpoint QoS**

`TopicEndpointInfo` now exposes its QoS profile, improving graph inspection and diagnostics.

### **Performance and Reliability**

This release includes performance improvements and fixes across action handling, dynamic-message introspection, sequence resizing, and `rosout` initialization.

### Breaking Changes

- Applications using generated ROS messages must add `ros-env` and use `use ros_env::*;`.
- ROS shim interfaces are now supplied through `ros-env`.
- `TopicEndpointInfo` exposes its QoS profile.
- Parameter callback APIs introduce breaking interface changes.

See the changelog ( [ros2\_rust/rclrs/CHANGELOG.md at main · ros2-rust/ros2\_rust · GitHub](https://github.com/ros2-rust/ros2_rust/blob/main/rclrs/CHANGELOG.md) ) for the complete list of changes.
