- Split the connector into two separate packages:`databricks-sql-connector` and`databricks-sqlalchemy`. The`databricks-sql-connector` package contains the core functionality of the connector, while the`databricks-sqlalchemy` package contains the SQLAlchemy dialect for the connector.

- Pyarrow dependency is now optional in`databricks-sql-connector`. Users needing arrow are supposed to explicitly install pyarrow

- Relaxed the number of Http retry attempts (databricks/databricks-sql-python#486 by@jprakash-db)

- Fix: Incorrect number of rows fetched in inline results when fetching results with FETCH_NEXT orientation (databricks/databricks-sql-python#479 by@jprakash-db)
