ROS 2 Iron Irwini Released!
Happy World Turtle Day! Today the ROS 2 Release Team is happy to announce the ninth release of ROS 2: Iron Irwini (codenamed iron).
In addition to the official logo shared previously, we also have a new Iron Irwini turtlesim icon. We’ve also added : iron : (
) and : irwini : (
) icons to ROS Discourse.
Iron Irwini is a standard support (i.e. not a long term support (LTS)) release that will be supported until November 2024. The distribution is primarily supported on the following platforms:
- Tier 1 platforms:
- Ubuntu 22.04 (Jammy): amd64 and arm64
- Windows 10 (Visual Studio 2019): amd64
- Tier 2 platforms:
- RHEL 9: amd64
- Tier 3 platforms:
- macOS: amd64
- Debian Bullseye: amd64
For more information about RMW implementations, compiler / interpreter versions, and system dependency versions see REP 2000.
Iron Irwini is feature packed and full of performance improvements. It’s worth going over the release notes and complete changelogs for core ROS 2 packages. Particularly it’s worth highlighting:
- Improved DDS Discovery Options to allow users to specify how ROS 2 performs discovery of nodes.
- Service Introspection which allows users to inspect the metadata and activities associated with an ongoing service.
- Documentation for core python APIs, e.g. rclpy.
- Events executor - a new experimental rclcpp executor with improved performance
If you are new to ROS, we recommend trying Iron Irwini on a Tier 1 supported platform. Check out the installation instructions and tutorials on docs.ros.org, and give Iron a spin! Should you run into any difficulties, please ask a question on ROS Answers.
ROS 2 is truly a community effort, and this could not have been better exemplified by our public beta testing of Iron Irwini over the past few weeks. Over 400 test cases were put through the ringer with several improvements identified along the way. It really helped “harden” the Iron distribution. The release team would like to extend a heartfelt thank you to all testers.
As a reminder, our T-shirt and swag campaign is still live to grab all the merch you can to support the release. All proceeds help support the Open Source Robotics Foundation (OSRF).
Thanks to the 239 contributors who contributed to this release through code changes, documentation, and testing.

ROS wouldn’t exist if it weren’t for all of our wonderful package maintainers. We’ve asked all of the package maintainers who plan to have their code ready for release today, or soon, to prepare “iron flexes” 
. In the comments below they’ll be posting brief updates about all of the new features they are bringing to Iron for their packages.
Finally, we’d like to announce the name of the next ROS 2 release for May 2024:
Jazzy Jalisco

. Moving forward, the team will aim to make patch releases of Open-RMF packages roughly monthly
