   ([#38139](https://github.com/apache/beam/issues/38139)).
 * (Python) Added type alias for with_exception_handling to be used for typehints. ([#38173](https://github.com/apache/beam/issues/38173)).
 * Added plugin mechanism to support different Lineage implementations (Java) ([#36790](https://github.com/apache/beam/issues/36790)).
+* (Python) Added [Qdrant](https://qdrant.tech/) VectorDatabaseWriteConfig implementation ([#38141](https://github.com/apache/beam/issues/38141)).
