+### Code Style and C++ conventions

+We require that all C++ code follows the conventions laid out [here](). `colcon test` will automatically check for deviations of style. If you'd like to have you're code autoformatted you can run the following command:

 ### Release
 * Open-RMF binaries for new ROS 2 distributions will be available along with the new release of ROS 2.
 * Roughly monthly, patch releases for packages with changes will be available in source and binary forms. All releases will be announced [here](https://github.com/open-rmf/rmf/releases)
