Release notes

2.0.45

Released: December 9, 2025

orm

[orm] [bug] Fixed issue where calling Mapper.add_property() within mapper event hooks such as MapperEvents.instrument_class(), MapperEvents.after_mapper_constructed(), or MapperEvents.before_mapper_configured() would raise an AttributeError because the mapper's internal property collections were not yet initialized. The Mapper.add_property() method now handles early-stage property additions correctly, allowing properties including column properties, deferred columns, and relationships to be added during mapper initialization events. Pull request courtesy G Allajmi.

examples

[examples] [bug] Fixed the "short_selects" performance example where the cache was being used in all the examples, making it impossible to compare performance with and without the cache. Less important comparisons like "lambdas" and "baked queries" have been removed.

sql

[sql] [bug] Some improvements to the _sql.ClauseElement.params() method to replace bound parameters in a query were made, however the ultimate issue in #12915 involving ORM _orm.aliased() cannot be fixed fully until 2.1, where the method is being rewritten to work without relying on Core cloned traversal.

[sql] [bug] Fixed issue where using the ColumnOperators.in_() operator with a nested CompoundSelect statement (e.g. an INTERSECT of UNION queries) would raise a NotImplementedError when the
