changelog</a>.</em></p>
<blockquote>
<h2>1.21.4</h2>
<ul>
<li>
<p>Fix unsoundness in <code>OnceCell::wait</code> under
<code>--features=parking_lot</code>, <a
href="https://redirect.github.com/matklad/once_cell/pull/295">#295</a>.</p>
<p>If thread A calls <code>wait</code>, while thread B calls
<code>get_or_try_init(f)</code>, and, furthermore, <code>f</code>
panics,
the <code>wait</code> incorrectly returns and thread A observes
uninitialized memory.</p>
<p>Kudos to <a
