<p><em>Sourced from <a
href="https://github.com/square/okhttp/blob/master/CHANGELOG.md">com.squareup.okhttp3:okhttp-bom's
changelog</a>.</em></p>
<blockquote>
<h2>Version 5.2.1</h2>
<p><em>2025-10-09</em></p>
<ul>
<li>
<p>Fix: Don't crash when calling <code>Socket.shutdownOutput()</code> or
<code>shutdownInput()</code> on an <code>SSLSocket</code>
on Android API 21 through 23. This method throws an
<code>UnsupportedOperationException</code>, so we now
catch that and close the underlying stream instead.</p>
</li>
<li>
<p>Upgrade: [Okio 3.16.1][okio_3_16_1].</p>
</li>
</ul>
<h2>Version 5.2.0</h2>
<p><em>2025-10-07</em></p>
<ul>
<li>
<p>New: Support [HTTP 101] responses with <code>Response.socket</code>.
This mechanism is only supported on
HTTP/1.1. We also reimplemented our websocket client to use this new
mechanism.</p>
</li>
<li>
<p>New: The <code>okhttp-zstd</code> module negotiates [Zstandard
(zstd)][zstd] compression with servers that
support it. It integrates a new (unstable) [ZSTD-KMP] library, also from
Square. Enable it like
this:</p>
<pre lang="kotlin"><code>val client = OkHttpClient.Builder()
  .addInterceptor(CompressionInterceptor(Zstd, Gzip))
  .build()
</code></pre>
</li>
<li>
<p>New: Support the <code>QUERY</code> HTTP method. You will need to set
the <code>Request.cacheUrlOverride</code>
property to cache calls made with this method. The
<code>RequestBody.sha256()</code> may be helpful here;
use it to compose a cache URL from the query body.</p>
</li>
<li>
<p>New: Publish events when calls must wait to execute.
<code>EventListener.dispatcherQueueStart()</code>
is invoked when a call starts waiting, and
<code>dispatcherQueueEnd()</code> is invoked when it's done.</p>
</li>
<li>
<p>New: <code>Request.toCurl()</code> returns a copy-pasteable [curl]
command consistent with Chrome’s and
Firefox’s ‘copy as cURL’ features.</p>
</li>
<li>
<p>New: Support [JPMS]. We replaced our
<code>Automatic-Module-Name</code> metadata with proper
<code>module-info.java</code> files.</p>
</li>
<li>
<p>Fix: Recover gracefully when worker threads are interrupted. When we
introduced fast fallback in
OkHttp 5.0, we started using background threads while connecting. Sadly
that code didn't handle
interruptions well. This is now fixed.</p>
</li>
<li>
<p>Upgrade: [Kotlin 2.2.20][kotlin_2_2_20].</p>
</li>
<li>
<p>Upgrade: [Okio 3.16.0][okio_3_16_0].</p>
</li>
</ul>
