What

The docs previously said each agent update produced a version numbered with a timestamp, and gave a timestamp example. They now say versions start at 1 and increment by one on each update.

Details
  • Also tightened: effort is the only field exempt from full replacement when you supply a model object, and supplying model without inference_geo clears any pinned geography.
