<blockquote>
<h1>1.18.4</h1>
<p>Released: February 10, 2026</p>
<h2>bug</h2>
<ul>
<li>
<p><strong>[bug] [operations]</strong> Reverted the behavior of
<code>Operations.add_column()</code> that would
automatically render the &quot;PRIMARY KEY&quot; keyword inline when a
<code>Column</code> with <code>primary_key=True</code> is added. The
automatic
behavior, added in version 1.18.2, is now opt-in via the new
<code>Operations.add_column.inline_primary_key</code> parameter. This
change restores the ability to render a PostgreSQL SERIAL column, which
is
required to be <code>primary_key=True</code>, while not impacting the
ability to
render a separate primary key constraint. This also provides consistency
with the <code>Operations.add_column.inline_references</code> parameter
and
gives users explicit control over SQL generation.</p>
<p>To render PRIMARY KEY inline, use the
<code>Operations.add_column.inline_primary_key</code> parameter set to
<code>True</code>:</p>
<p>op.add_column(
&quot;my_table&quot;,
Column(&quot;id&quot;, Integer, primary_key=True),
inline_primary_key=True
)References: <a

</li>
</ul>
<h1>1.18.3</h1>
<p>Released: January 29, 2026</p>
<h2>bug</h2>
<ul>
<li>
<p><strong>[bug] [autogenerate]</strong> Fixed regression in version
1.18.0 due to <a
href="https://redirect.github.com/sqlalchemy/alembic/issues/1771">#1771</a>
where autogenerate
would raise <code>NoReferencedTableError</code> when a foreign key
constraint
referenced a table that was not part of the initial table load,
including
tables filtered out by the
<code>EnvironmentContext.configure.include_name</code> callable or
tables
in remote schemas that were not included in the initial reflection
run.</p>
<p>The change in <a
href="https://redirect.github.com/sqlalchemy/alembic/issues/1771">#1771</a>
was a performance optimization that eliminated
additional reflection queries for tables that were only referenced by
foreign keys but not explicitly included in the main reflection run.
However, this optimization inadvertently removed the creation of
<code>Table</code> objects for these referenced tables, causing
autogenerate
to fail when processing foreign key constraints that pointed to
them.</p>
<p>The fix creates placeholder <code>Table</code> objects for foreign
key targets</p>
