would it be possible to limit your changes to a smaller bounding box? -133.418,-42.163,183.455,55.952 (or, half the world) seems to be a little big for a change of 12 nodes and 3 ways [1]. as all your airport changes use such a big bounding box, history for a small area (like mine [2]) is not meaningful anymore.

thank you!
