Data API supports a new metadata field, "publishing_stage" to help you understand an item's publishing lifecycle and make decisions on when to download an item, based on whether your pipeline needs to optimize for data latency or data accuracy. This field is searchable and returned in the metadata.json file for all PlanetScope and SkySat items, published after June 19, 2020. More information on this field is available here: https://developers.planet.com/docs/data/items-assets/
