    • Need to widen it to 32 bits

UTC2347 - metadata corrections in parameter metadata

  • Removes the values examples
  • UI issue in MissionPlanner
    • Can’t set an arbitrary value
  • We’ll close this issue and open one against MissionPlanner

UTC2354 - AP_NavEKF3: make time-horizon OF data a local variable by peterbarker · Pull Request #17585 · ArduPilot/ardupilot · GitHub

  • Moves global state to be a stack variable
  • Saves 60 bytes of RAM per EK3 core
  • merged

UTC0008 - Copter: these two errors are too common to be called "emergency" by tridge · Pull Request #17574 · ArduPilot/ardupilot · GitHub

  • We’ll go with notice for now
  • For 4.1
  • False-positives are killing the utility of this patch set
  • PH does the yaw imbalance
  • LTH is responsible for thrust-loss
  • 50% emergency?

  • Otherwise notice
  • Maybe a must-be-flying-for-10-seconds before warning threshold
  • Moving to be a warning based on imax not i
  • Rate graph should be used for actually looking for problems on a vehicle in the logs
  • Tagged as MergeOnCIPass
