• @emersonknapp feedback on improvements to launch:

  • Allow actions to take a single text element, rather than an array or struct:
    • Allow `include:` to take a single text element instead of requiring `file:` by emersonknapp · Pull Request #867 · ros2/launch · GitHub

  • General housekeeping around Python launch files in documentation:
