News and Updates

SQLAlchemy 2.1.7 is now available.

Release 2.1.7 fixes a series of regressions in the 2.1 series, mostly in the ORM, including issues with ORM-native dataclass mappings, selectinload() against aliased many-to-many targets, and execution options applied within SAVEPOINTs, as well as a pool regression where garbage collected connections were not returned to the pool on Python 3.15. The release also adds new SessionTransaction.connections and SessionTransaction.bound_connection() accessors, improves typing so that constructs such as Column(Integer) may be assigned to a wider declared type such as Column[int | None], and includes the fixes that were also released in 2.0.56.

The detailed changelog for 2.1.7 is at Changelog.
