<h2>Tokio v1.16.1</h2>
<h1>1.16.1 (January 28, 2022)</h1>
<p>This release fixes a bug in <a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4428">#4428</a> with the change <a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4437">#4437</a>.</p>
<p><a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4428">#4428</a>: <a href="https://github-redirect.dependabot.com/tokio-rs/tokio/pull/4428">tokio-rs/tokio#4428</a>
<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4437">#4437</a>: <a href="https://github-redirect.dependabot.com/tokio-rs/tokio/pull/4437">tokio-rs/tokio#4437</a></p>
<h2>Tokio v1.16.0</h2>
<p>Fixes a soundness bug in <code>io::Take</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4428">#4428</a>). The unsoundness is exposed when
leaking memory in the given <code>AsyncRead</code> implementation and then overwriting the
supplied buffer:</p>
<pre lang="rust"><code>impl AsyncRead for Buggy {
    fn poll_read(
        self: Pin&lt;&amp;mut Self&gt;,
        cx: &amp;mut Context&lt;'_&gt;,
        buf: &amp;mut ReadBuf&lt;'_&gt;
    ) -&gt; Poll&lt;Result&lt;()&gt;&gt; {
      let new_buf = vec![0; 5].leak();
      *buf = ReadBuf::new(new_buf);
      buf.put_slice(b&quot;hello&quot;);
      Poll::Ready(Ok(()))
    }
}
</code></pre>
<p>Also, this release includes improvements to the multi-threaded scheduler that
can increase throughput by up to 20% in some cases (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4383">#4383</a>).</p>
<h3>Fixed</h3>
<ul>
<li>io: <strong>soundness</strong> don't expose uninitialized memory when using <code>io::Take</code> in edge case (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4428">#4428</a>)</li>
<li>fs: ensure <code>File::write</code> results in a <code>write</code> syscall when the runtime shuts down (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4316">#4316</a>)</li>
<li>process: drop pipe after child exits in <code>wait_with_output</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4315">#4315</a>)</li>

<li>rt: reduce false-positive thread wakups in the multi-threaded scheduler (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4383">#4383</a>)</li>

</ul>
<h3>Added</h3>
<ul>
<li>net: <code>TcpSocket::linger()</code> and <code>set_linger()</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4324">#4324</a>)</li>
<li>net: impl <code>UnwindSafe</code> for socket types (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4384">#4384</a>)</li>
<li>rt: impl <code>UnwindSafe</code> for <code>JoinHandle</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4418">#4418</a>)</li>
<li>sync: <code>watch::Receiver::has_changed()</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4342">#4342</a>)</li>
<li>sync: <code>oneshot::Receiver::blocking_recv()</code> (<a href="https://github-redirect.dependabot.com/tokio-rs/tokio/issues/4334">#4334</a>)</li>
