SQLAlchemy 2.1.0 Released

SQLAlchemy 2.1.0, released September 24, 2026, is the first production release of the 2.1 series and becomes the version installed by default with pip install sqlalchemy. Upgrades from 2.0 are generally straightforward but include a set of harder, breaking changes that will require some workflow adjustments: the greenlet dependency used for asyncio features is no longer installed automatically (install via pip install sqlalchemy asyncio), driver-less PostgreSQL and Oracle URLs now default to psycopg (psycopg3) and oracledb respectively, and Python 3.11 is now the minimum supported Python version.

Major feature additions include tstring(), a variant of text() that allows dynamically indicated bind parameters inside plain SQL strings; explicit CreateView and CREATE TABLE AS support; and official support for Microsoft’s mssql-python driver through collaboration with Microsoft. The release encompasses many other fixes and improvements accumulated over three years since 2.0, so users should consult the 2.1 migration guide and full changelog for detailed guidance. SQLAlchemy 2.1.0 is available for download on the project’s release page.
