<blockquote>
<h1>2.0.42</h1>
<p>Released: July 29, 2025</p>
<h2>orm</h2>
<ul>
<li>
<p><strong>[orm] [usecase]</strong> Added <code>dataclass_metadata</code> argument to all ORM attribute constructors
that accept dataclasses parameters, e.g. <code>mapped_column.dataclass_metadata</code>,
<code>relationship.dataclass_metadata</code>, etc.
It's passed to the underlying dataclass <code>metadata</code> attribute
of the dataclass field. Pull request courtesy Sigmund Lahn.</p>
<p>References: <a href="https://www.sqlalchemy.org/trac/ticket/10674">#10674</a></p>
</li>
<li>
<p><strong>[orm] [bug]</strong> Implemented the <code>_orm.defer()</code>, <code>_orm.undefer()</code> and
<code>_orm.load_only()</code> loader options to work for composite attributes, a
use case that had never been supported previously.</p>
<p>References: <a href="https://www.sqlalchemy.org/trac/ticket/12593">#12593</a></p>
</li>
<li>
<p><strong>[orm] [bug]</strong> Fixed bug where the ORM would pull in the wrong column into an UPDATE when
a key name inside of the <code>ValuesBase.values()</code> method could be located
from an ORM entity mentioned in the statement, but where that ORM entity
was not the actual table that the statement was inserting or updating.  An
extra check for this edge case is added to avoid this problem.</p>
<p>References: <a href="https://www.sqlalchemy.org/trac/ticket/12692">#12692</a></p>
</li>
</ul>
<h2>engine</h2>
<ul>
<li><strong>[engine]</strong> Improved validation of execution parameters passed to the
<code>_engine.Connection.execute()</code> and similar methods to
provided a better error when tuples are passed in.
Previously the execution would fail with a difficult to
understand error message.</li>
</ul>
<h2>sql</h2>
<ul>
<li>
<p><strong>[sql] [usecase]</strong> The <code>_sql.values()</code> construct gains a new method <code>_sql.Values.cte()</code>,
which allows creation of a named, explicit-columns <code>CTE</code> against an
unnamed <code>VALUES</code> expression, producing a syntax that allows column-oriented
selection from a <code>VALUES</code> construct on modern versions of PostgreSQL, SQLite,
and MariaDB.</p>
