+- MARC: Added support for filtering fields (see Marc::filterFields).
+- LIDO: Added support for filtering repository locations.
+- QDC: Added a driver param (preferredFormatTypes) to indicate preferred dc.type fields for format.
+- Added optional index hints for PDO databases. Not useful in most cases.

+- Enhanced the export function:
+  - Added support for timestamp injection

 ### Changed
