Dear ROS Community,
Gazebo Citadel has reached end-of-life (EOL) as of December, 2024. Citadel was released in December, 2019 and it was the third major release of Gazebo (named Ignition back then). It was a milestone release because it was the first Long Term Supported (LTS) release of Gazebo with support lasting 5 years. Citadel introduced various exciting features, including SDF frame semantics, Animated actors, Visualization markers, Thermal camera sensors, CLI to Upload models to Fuel, and Rechargeable batteries to name a few. See the entire list of features on the Release Features page.
We recommend all Citadel users migrate to a supported release as soon as possible, such as Harmonic (LTS) or Ionic, which are paired with ROS Jazzy and Rolling (Kilted once released) respectively. Migrating to either Harmonic or Ionic will require migrating from Ignition to Gazebo, so please follow the migration guide. Also, be sure to check the release highlights for Harmonic and Ionic in addition to checking each libraryโs migration guide.
As part of the Citadel EOL, the following Gazebo libraries have also reached end-of-life. Their latest released binaries will remain available at http://packages.osrfoundation.org/, but no more fixes or releases will be made.
Library major version | Final release |
---|---|
gz-gui3 (ignition-gui3) | 3.12.0 |
gz-launch2 (ignition-launch2) | 2.3.1 |
gz-physics2 (ignition-physics2) | 2.6.2 |
gz-rendering3 (ignition-rendering3) | 3.7.2 |
gz-sensors3 (ignition-sensors3) | 3.6.0 |
gz-sim3 (ignition-gazebo3) | 3.15.1 |
We sincerely thank all contributors to all libraries in Citadel
What does End of Life Mean?
Users often ask us, โwhat does end of life mean?โ To put it briefly, end of life means that the Gazebo team will no longer support that particular Gazebo release. In practical terms, this means that we will no longer be providing the following for Gazebo Citadel:
- New features or capabilities
- Security updates
- Bug fixes, patches or support
- Updated binaries
It is also worth noting the things that wonโt change after Gazebo Citadel goes end of life:
- Gazebo Citadel binaries will not suddenly disappear
- Users will not need to migrate immediately, but they should migrate as soon as possible
