Release notes

Sourced from sqlalchemy's releases.

2.1.5

Released: October 16, 2026

orm

• [orm] [feature] Added the _orm.Unmapped annotation and the _orm.unmapped_column() construct, providing a declarative-compatible approach to having "excluded" columns in a Declarative model, that is, columns that are part of the _schema.Table but are not mapped, replacing the use of _orm.Mapper.exclude_properties for this purpose when using a Declarative mapping.

• [orm] [bug] [regression] Fixed regression caused by #11917 in version 2.0.36 where an ORM enabled _sql.update() using WHERE criteria which matched more than one object present in the _orm.Session would expire server-side onupdate columns, as well as columns that were SET to a SQL expression, on only one of the matched objects, leaving the remaining objects with stale values for those attributes. The columns are now expired for all matched objects.

  This change is also backported to: 2.0.55

• [orm] [deprecated] Using the _orm.Mapper.exclude_properties or _orm.Mapper.include_properties parameters on a Declarative mapping to exclude attributes that are declared on the class, such as with _orm.mapped_column(), is deprecated and now emits a deprecation warning. This use was never supported, and depending on the arguments passed to _orm.mapped_column(), the attribute could remain mapped regardless; in particular, as of 2.1 this includes ORM mapped dataclasses where _orm.mapped_column.default is present. The new _orm.unmapped_column() construct should be used instead. Excluding columns that are present only in the _schema.Table, such as those from __table__, __table_args__ or table reflection, is not affected.

schema

• [schema] [bug] Fixed issue where dialect-specific keyword arguments established on a ForeignKeyConstraint, ForeignKey or CheckConstraint, such as postgresql_not_valid, were not carried along to the copy of the constraint produced by
