  by setting ENABLE_INGEST_ACTION_TRUNCATE to true.

Changed

• When being ingested, Items and Collection without a links array will not be rejected,
  but will have the field added.

v4.1.0

[4.1.0] - 2024-04-22

Changed

• breaking Collections Auth features (ENABLE_COLLECTIONS_AUTHX) now fails closed

  with ENABLE_THUMBNAILS = true.

v4.0.0

Removed

• Context Extension is now disabled by default, and can be enabled with ENABLE_CONTEXT_EXTENSION

  STAC_VERSION environment variable. This is now fixed at 1.1.0.
• Child link relations removed from root (landing page).

Changed

• Use Node 22 by default.

Added

• To all endpoints that depend on collections, add support for a query parameter (GET)
  or body field (POST) _collections that will filter to only those collections, but
  will not reveal that in link contents. This is controlled by the "ENABLE_COLLECTIONS_AUTHX"

[3.11.0] - 2025-03-27

Added

• Support for the "in" and "between" operators of the Filter Extension
• Support for "s_intersects" opeartor of the Filter Extension. This implements both the
  "Basic Spatial Functions" and "Basic Spatial Functions with additional Spatial Literals"
  conformance classes, supporting operands for s_intersects of either bbox or GeoJSON
  Geometry literals.

v3.10.0

[3.10.0] - 2025-03-21

Changed

• Use Node 20 by default. Node 20 will be supported by AWS into 2026. Upgrade was
  not done to Node 22 because it requires upgrading the ava/typescript library.
• The default stac_version for the root Catalog / Landing page is now 1.1.0.

Fixed

• Removed inapplicable stac_version and stac_extensions fields from ItemCollection

v3.9.0

Changed

• Update to default to OpenSearch 2.17

Added

• Minimum implementation (basic-cql2 conformance class) of the filter extension for the
  /search (GET and POST), /collections/{collectionId}/items (GET), and /aggregate
  (GET) endpoints. Only CQL2 JSON is supported.

v3.8.0

Changed

• Update to default to OpenSearch 2.13

v3.7.0

Fixed

• For the first item indexed in a new collection, if all values in the
  proj:transform array were integers, the values were typed as integers,
  which would then cause an error for subsequent items that had float values
  in the array.

Added

• Allow the following CORS headers to be configured with configuration variables:
  • Access-Control-Allow-Origin: CORS_ORIGIN
  • Access-Control-Allow-Credentials: CORS_CREDENTIALS
  • Access-Control-Allow-Methods: CORS_METHODS
  • Access-Control-Allow-Headers: CORS_HEADERS

v3.6.0

Changed

• Deprecated grid_geohex_frequency, grid_geohash_frequency, and
  grid_geotile_frequency aggregations in favor of new centroid_geohash_grid_frequency,
  centroid_geohex_grid_frequency, and centroid_geotile_grid_frequency aggregations

Added

• Added geometry_geohash_grid_frequency and geometry_geotile_grid_frequency that
  aggregate over the geometry of each Item rather than the centroid. Note that the geohex aggregation geometry_geohex_grid_frequency is not implemented, as OpenSearch 2.11
  does not yet support geohex_grid aggregations over geo_shape fields.
