<blockquote>
<h2>v2.34.2</h2>
<h2>2.34.2 (2026-05-14)</h2>
<ul>
<li>Moved <code>headers</code> input type back to <code>Mapping</code>
to avoid invariance issues with <code>MutableMapping</code> and inferred
dict types. Users calling <code>Request.headers.update()</code> may need
to narrow typing in their code. (<a
