I’m surprised there isn’t more noise about this: The STAC API Specification has reached its 1.0 milestone.

While core STAC specification defines interfaces to publish and organise data in catalogues and collections, STAC API adds dynamic interfaces to enable machines to search and crawl datasets. For example, it adds STAC search, allowing clients to find STAC items across collections, based on filter criteria like a bounding box or date ranges and more complex queries against specific data properties, like cloud cover.

STAC API 1.0 is a continuation of the 0.9 specification, its previous release. The updated specification introduces a long list of changes; few are fundamental, but some are breaking changes—hence the major-version increase. For a detailed list of changes, check the changelog.
