<p><em>Sourced from <a href="https://github.com/square/okio/blob/master/CHANGELOG.md">com.squareup.okio:okio's changelog</a>.</em></p>
<blockquote>
<h2>Version 3.9.0</h2>
<p><em>2024-03-12</em></p>
<ul>
<li>New: <code>FileSystem.SYSTEM</code> can be used in source sets that target both Kotlin/Native and
Kotlin/JVM. Previously, we had this symbol in each source set but it wasn't available to
common source sets.</li>
<li>New: <code>COpaquePointer.readByteString(...)</code> creates a ByteString from a memory address.</li>
<li>New: Support <code>InflaterSource</code>, <code>DeflaterSink</code>, <code>GzipSink</code>, and <code>GzipSource</code> in Kotlin/Native.</li>
<li>New: Support openZip() on Kotlin/Native. One known bug in this implementation is that
<code>FileMetadata.lastModifiedAtMillis()</code> is interpreted as UTC and not the host machine's time zone.</li>
<li>New: Prefer NTFS timestamps in ZIP file systems' metadata. This avoids the time zone problems
of ZIP's built-in DOS timestamps, and the 2038 time bombs of ZIP's extended timestamps.</li>
<li>Fix: Don't leak file handles to opened JAR files open in <code>FileSystem.RESOURCES</code>.</li>
<li>Fix: Don't throw a <code>NullPointerException</code> if <code>Closeable.use { ... }</code> returns null.</li>
</ul>
