 ### Changed
 
+- **Vacuum Retention**: Default `vacuum_retention_seconds` increased from 60 seconds to 86400 seconds (1 day) for better version retention in typical workflows
 - **BREAKING**: Major refactoring of graph-related code into unified `haiku.rag.graph` module structure:
   - `haiku.rag.research` → `haiku.rag.graph.research`
   - `haiku.rag.qa.deep` → `haiku.rag.graph.deep_qa`

-**Automatic Cleanup:** Vacuum runs automatically in the background after document operations. By default, it removes versions older than 60 seconds (configurable via `storage.vacuum_retention_seconds`), preserving recent versions for concurrent connections. Manual vacuum can be useful for cleanup after bulk operations or to free disk space immediately.
