v4.5.0

[4.5.0]

Added

• Asset proxying for generating pre-signed S3 URLs through proxy endpoints GET /collections/{collectionId}/items/{itemId}/assets/{assetKey} and GET /collections/{collectionId}/assets/{assetKey}.
• Environment variables ASSET_PROXY_BUCKET_OPTION, ASSET_PROXY_BUCKET_LIST, and
  ASSET_PROXY_URL_EXPIRY to configure asset proxying.

Changed

• When asset proxying is enabled, when a STAC Item or Collection is served, asset S3 hrefs
  are replaced with proxy endpoint URLs and the original S3 URLs are preserved in
  alternate.s3.href using the Alternate Assets Extension.

Fixed

• When using the _filter parameter, the combined filter was returned in the next link
  body. This had the correct semantics, but the size of the filter would grow by one
  and nesting each pagination request, as the _filter was repeatedly added to body.

v4.4.0

Changed

• If a request includes the STAC-Endpoint header, that endpoint will be used when generating link hrefs.
  This deprecates (but still supports) the X-STAC-Endpoint header. This change is in order to comply
  with the proprietary header name recommendations in RFC 6648.

Added

• To all endpoints that accept a filter parameter, add support for a query parameter (GET)
  or body field (POST) _filter or a header STAC-Filter-Authx that will "and" a CQL2
  filter expression to the user's
  request, such that the extra expression will not be
  will not be revealed in link contents. This is controlled by the ENABLE_FILTER_AUTHX
  environment variable.
• To all endpoints that already support the _collections parameter, also support a
  header STAC-Collections-Authx to pass the value.

v4.3.0

Changed

• Compression is enabled by default, can be disabled by setting
  ENABLE_RESPONSE_COMPRESSION to false. If using post-hooks, you must update
  to hooks to handle compression or disable compression.
• Update to default to OpenSearch 2.19

Added

• The maximum limit for the number of items returned from the /search and
  /collections/{collection_id}/items endpoints can now be configured with the
  ITEMS_MAX_LIMIT variable. It is recommended that this be set to 100.

v4.2.0

Added

• Added support for ingest actions, specifically "truncate collection". This is enabled
  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.

Removed

• From ingest.js, removed combineDbObjectsIntoBulkOperations and writeRecordsInBulkToDb
  functions, as they have not been used since version 2.0.0.

v4.1.0

[4.1.0] - 2024-04-22

Changed

• breaking Collections Auth features (ENABLE_COLLECTIONS_AUTHX) now fails closed
  rather than open. If _collections is not specified or is empty, caller has no
  access to collections. Also, adds a special collection name * that means access
  to all collections is granted.
• breaking The thumbnails behavior is now disabled by default, and can be enabled
  with ENABLE_THUMBNAILS = true.

v4.0.0

Removed

• Context Extension is now disabled by default, and can be enabled with ENABLE_CONTEXT_EXTENSION
• Removed configurability of the Root / Landing Page Catalog stac_version via the
  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"

v4.0.0-rc.1

[4.0.0-rc.1] - 2025-04-07

Removed

• Context Extension is not disabled by default, and can be enabled with ENABLE_CONTEXT_EXTENSION
• Removed configurability of the Root / Landing Page Catalog stac_version via the
  STAC_VERSION environment variable. This is now fixed at 1.1.0.
• Child link relations removed from root (landing page).

Changed

v3.11.0

[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

  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.

Fixed

• Removed inapplicable stac_version and stac_extensions fields from ItemCollection

v3.9.0

Changed

• Update to default to OpenSearch 2.17
