[dependabot]

Bumps sqlalchemy from 2.0.43 to 2.0.49.

Release notes

Sourced from sqlalchemy's releases.

2.0.49

Released: April 3, 2026

orm

• [orm] [bug] Fixed issue where _orm.Session.get() would bypass the identity map and emit unnecessary SQL when with_for_update=False was passed, rather than treating it equivalently to the default of None. Pull request courtesy of Joshua Swanson.

• [orm] [bug] Fixed issue where chained _orm.joinedload() options would not be applied correctly when the final relationship in the chain is declared on a base mapper and accessed through a subclass mapper in a _orm.with_polymorphic() query. The path registry now correctly computes the natural path when a property declared on a base class is accessed through a path containing a subclass mapper, ensuring the loader option can be located during query compilation.

• [orm] [bug] [inheritance] Fixed issue where using _orm.Load.options() to apply a chained loader option such as _orm.joinedload() or _orm.selectinload() with _orm.PropComparator.of_type() for a polymorphic relationship would not generate the necessary clauses for the polymorphic subclasses. The polymorphic loading strategy is now correctly propagated when using a call such as joinedload(A.b).options(joinedload(B.c.of_type(poly))) to match the behavior of direct chaining e.g. joinedload(A.b).joinedload(B.c.of_type(poly)).

• [orm] [bug] [inheritance] Fixed issue where using chained loader options such as _orm.selectinload() after _orm.joinedload() with _orm.PropComparator.of_type() for a polymorphic relationship would not properly apply the chained loader option. The loader option is now correctly applied when using a call such as joinedload(A.b.of_type(poly)).selectinload(poly.SubClass.c) to eagerly load related objects.

typing

• [typing] [bug] Fixed a typing issue where the typed members of :data:.func would return the appropriate class of the same name, however this creates an issue for

If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
