New bugs of note:

  • MPPI binaries are broken fix coming in 1.2.5 and 1.1.12 for Humble/Iron

Anything else?

  • Alejandro & Ben & Ryan – Gazebo vs Ignition migration status and check (@ahcorde)
    • New gazebo performs worse than gazebo classic (80% vs 100% CPU)
    • Something seems very wrong; costmaps not showing up and state estimation is running away
    • Can we skip Ignition and just go to Gazebo2? Can do in all bridge, etc. The world file is only thing that needs to be updated later.
