<p><em>Sourced from <a href="https://github.com/square/okhttp/blob/master/CHANGELOG.md">okhttp's changelog</a>.</em></p>
<blockquote>
<h2>Version 4.9.1</h2>
<p><em>2021-01-30</em></p>
<ul>
<li>Fix: Work around a crash in Android 10 and 11 that may be triggered when two threads
concurrently close an SSL socket. This would have appeared in crash logs as
<code>NullPointerException: bio == null</code>.</li>
</ul>
<h2>Version 4.9.0</h2>
<p><em>2020-09-11</em></p>
<p><strong>With this release, <code>okhttp-tls</code> no longer depends on Bouncy Castle and doesn't install the
Bouncy Castle security provider.</strong> If you still need it, you can do it yourself:</p>
<pre><code>Security.addProvider(BouncyCastleProvider())
</code></pre>
<p>You will also need to configure this dependency:</p>
<pre><code>dependencies {
  implementation &quot;org.bouncycastle:bcprov-jdk15on:1.65&quot;
}
</code></pre>
<ul>
<li>Upgrade: [Kotlin 1.4.10][kotlin_1_4_10]. We now use Kotlin 1.4.x [functional
interfaces][fun_interface] for <code>Authenticator</code>, <code>Interceptor</code>, and others.</li>
<li>Upgrade: Build with Conscrypt 2.5.1.</li>
</ul>
<h2>Version 4.8.1</h2>
<p><em>2020-08-06</em></p>
<ul>
<li>Fix: Don't crash in <code>HeldCertificate.Builder</code> when creating certificates on older versions of
Android, including Android 6. We were using a feature of <code>SimpleDateFormat</code> that wasn't
available in those versions!</li>
</ul>
<h2>Version 4.8.0</h2>
<p><em>2020-07-11</em></p>
<ul>
<li>New: Change <code>HeldCertificate.Builder</code> to use its own ASN.1 certificate encoder. This is part
of our effort to remove the okhttp-tls module's dependency on Bouncy Castle. We think Bouncy
Castle is great! But it's a large dependency (6.5 MiB) and its security provider feature
impacts VM-wide behavior.</li>
</ul>
