 # Changelog
 ## [Unreleased]
 
+### Fixed
+
+- **Relative `db_path` no longer trips the LanceDB cloud-URI sanitizer.** The 0.43 migration to `lancedb.connect_async` started routing the path through an async URI sanitizer that treats anything not clearly an absolute local path as a possible cloud URI, raising `ValueError: An api_key is required when connecting to LanceDb Cloud` on invocations like `haiku-rag info --db db/rag.lancedb`. The path is now made absolute before being handed to LanceDB.

 ## [0.43.0] - 2026-04-24
