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/

Data API supports a new filter option: UpdateFilter. This filter can be used to filter items by changes to a specified metadata field value made after a specified date. It allows users to identify items which may have been republished with quality improvements or fixes, enabling them to keep internal catalogs up-to-date and make more informed redownload decisions. You can read more on this filter type here: https://developers.planet.com/docs/data/searches-filtering/#updatefilter

• Data API now returns a list of supported asset types for each item type in all GET item_types calls. This field lists the set of asset types which may be produced for a given item type. You can reference this change in our API reference documentation here: https://developers.planet.com/docs/apis/data/reference/#operation/ListItemTypes

• analytic_sr assets are now available for PSOrthoTile and REOrthoTile item types. You can search for and order these assets via the Data API, Orders API (analytic_sr product bundle), and Python CLI.

Filtering items by available assets is now available via the AssetFilter filtering option of the Data API. More information on this filter type is available here: https://developers.planet.com/docs/data/searches-filtering/#asset-filters
