News and Updates

SQLAlchemy release 2.0.10 is now available.

Release 2.0.10 revisits the original reason that version 2.0.9 was released quickly, involving apparent row ordering when using RETURNING with SQLAlchemy 2.0's "insertmanyvalues" feature, which had to be disabled for Microsoft SQL Server.

In version 2.0.10, "insertmanyvalues" has gained a new optional RETURNING feature called sort_by_parameter_order which enables a new set of INSERT forms and execution models which ensure these ordering guarantees take place for each of the supported backends SQL Server, PostgreSQL, SQLite and MariaDB. As a result the "insertmanyvalues" performance optimization is re-enabled for SQL Server. For other backends, while no row-ordering issues were observed or reproduced, the new guarantees change how the feature is implemented as used by the ORM. A new documentation section linked from the changelog illustrates the feature in depth.
