* Fixed bug where SQL functions passed to
:paramref:`_schema.Column.server_default` would not be rendered with the
particular form of parenthesization now required by newer versions of MySQL
and MariaDB. Pull request courtesy of huuya.
* Fixed bug in ORM bulk update/delete where using RETURNING with bulk
update/delete in combination with ``populate_existing`` would fail to
accommodate the ``populate_existing`` option.
* Continuing from 🎫`11912`, columns marked with
:paramref:`.mapped_column.onupdate`,
:paramref:`.mapped_column.server_onupdate`, or :class:`.Computed` are now
refreshed in ORM instances when running an ORM enabled UPDATE with WHERE
criteria, even if the statement does not use RETURNING or
``populate_existing``.
* Added new parameter :paramref:`_orm.mapped_column.hash` to ORM constructs
such as :meth:`_orm.mapped_column`, :meth:`_orm.relationship`, etc.,
which is interpreted for ORM Native Dataclasses in the same way as other
dataclass-specific field parameters.
* Fixed bug in reflection of table comments where unrelated text would be
returned if an entry in the ``pg_description`` table happened to share the
same oid (objoid) as the table being reflected.
* Fixed regression caused by fixes to joined eager loading in 🎫`11449`
released in 2.0.31, where a particular joinedload case could not be
asserted correctly. We now have an example of that case so the assertion
has been repaired to allow for it.
* Improved the error message emitted when trying to map as dataclass a class
while also manually providing the ``__table__`` attribute.
This usage is currently not supported.
* Improved a query used for the MySQL 8 backend when reflecting foreign keys
to be better optimized. Previously, for a database that had millions of
