+## [4.2.0] - unreleased
+
+### 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.
