<blockquote>
<h2>Version 7.6.1 — 2024-08-04</h2>
<ul>
<li>
<p>Fix: coverage used to fail when measuring code using
:func:<code>runpy.run_path &lt;python:runpy.run_path&gt;</code> with a
:class:<code>Path &lt;python:pathlib.Path&gt;</code> argument.
This is now fixed, thanks to <code>Ask Hjorth Larsen &lt;pull
1819_&gt;</code>_.</p>
</li>
<li>
<p>Fix: backslashes preceding a multi-line backslashed string could
confuse the
HTML report. This is now fixed, thanks to <code>LiuYinCarl &lt;pull
1828_&gt;</code>_.</p>
</li>
<li>
<p>Now we publish wheels for Python 3.13, both regular and
free-threaded.</p>
</li>
</ul>

<blockquote>
<h1>2.0.32</h1>
<p>Released: August 5, 2024</p>
<h2>general</h2>
<ul>
<li>
<p><strong>[general] [bug] [regression]</strong> Restored legacy class
names removed from
<code>sqlalalchemy.orm.collections.*</code>, including
<code>_orm.MappedCollection</code>,
<code>_orm.mapped_collection()</code>,
<code>_orm.column_mapped_collection()</code>,
<code>_orm.attribute_mapped_collection()</code>. Pull request courtesy
Takashi
Kajinami.</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/11435">#11435</a></p>
</li>
</ul>
<h2>orm</h2>
<ul>
<li>
<p><strong>[orm] [usecase]</strong> The <code>_orm.aliased.name</code>
parameter to <code>_orm.aliased()</code> may now
be combined with the <code>_orm.aliased.flat</code> parameter, producing
per-table names based on a name-prefixed naming convention. Pull request
courtesy Eric Atkin.</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/11575">#11575</a></p>
</li>
<li>
<p><strong>[orm] [bug] [regression]</strong> Fixed regression going back
to 1.4 where accessing a collection using the
&quot;dynamic&quot; strategy on a transient object and attempting to
query would
raise an internal error rather than the expected
<code>NoResultFound</code>
that occurred in 1.3.</p>
<p>This change is also <strong>backported</strong> to: 1.4.53</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/11562">#11562</a></p>
</li>
<li>
<p><strong>[orm] [bug]</strong> Fixed issue where using the
<code>_orm.Query.enable_eagerloads()</code> and
<code>_orm.Query.yield_per()</code> methods at the same time, in order
to disable
eager loading that's configured on the mapper directly, would be
silently
ignored, leading to errors or unexpected eager population of
attributes.</p>
<p>References: <a
href="https://www.sqlalchemy.org/trac/ticket/10834">#10834</a></p>
</li>
<li>
<p><strong>[orm] [bug] [regression]</strong> Fixed regression appearing
in 2.0.21 caused by <a
href="https://www.sqlalchemy.org/trac/ticket/10279">#10279</a> where
using
a <code>_sql.delete()</code> or <code>_sql.update()</code> against an
ORM class that is
the base of an inheritance hierarchy, while also specifying that
subclasses
should be loaded polymorphically, would leak the polymorphic joins into
the
UPDATE or DELETE statement as well creating incorrect SQL.</p>

href="https://www.sqlalchemy.org/trac/ticket/11625">#11625</a></p>

<li>
<p><strong>[orm] [bug] [regression]</strong> Fixed regression from
version 1.4 in</p>
