<blockquote>
<h1>7.2.2</h1>
<p>2026-01-28</p>
<p><strong>Enhancements</strong></p>
<ul>
<li>2705_: [Linux]: <code>Process.wait()</code>_ now uses
<code>pidfd_open()</code> + <code>poll()</code> for
waiting, resulting in no busy loop and faster response times. Requires
Linux &gt;= 5.3 and Python &gt;= 3.9. Falls back to traditional polling
if
unavailable.</li>
<li>2705_: [macOS], [BSD]: <code>Process.wait()</code>_ now uses
<code>kqueue()</code> for waiting,
resulting in no busy loop and faster response times.</li>
</ul>
<p><strong>Bug fixes</strong></p>
<ul>
<li>2701_, [macOS]: fix compilation error on macOS &lt; 10.7. (patch by
Sergey
Fedorov)</li>
<li>2707_, [macOS]: fix potential memory leaks in error paths of
<code>Process.memory_full_info()</code> and
<code>Process.threads()</code>.</li>
<li>2708_, [macOS]: Process.cmdline()<code>_ and
</code>Process.environ()<code>_ may fail with ``OSError: [Errno 0]
Undefined error`` (from ``sysctl(KERN_PROCARGS2)``). They now raise
</code>AccessDenied`_ instead.</li>
</ul>
<h1>7.2.1</h1>
<p>2025-12-29</p>
<p><strong>Bug fixes</strong></p>
<ul>
<li>2699_, [FreeBSD], [NetBSD]: <code>heap_info()</code>_ does not
detect small allocations
(&lt;= 1K). In order to fix that, we now flush internal jemalloc cache
before
fetching the metrics.</li>
</ul>
<h1>7.2.0</h1>
<p>2025-12-23</p>
<p><strong>Enhancements</strong></p>
<ul>
<li>1275_: new <code>heap_info()</code>_ and <code>heap_trim()</code>_
functions, providing direct
access to the platform's native C heap allocator (glibc, mimalloc,
libmalloc). Useful to create tools to detect memory leaks.</li>
<li>2403_, [Linux]: publish wheels for Linux musl.</li>
<li>2680_: unit tests are no longer installed / part of the
distribution. They
now live under <code>tests/</code> instead of
<code>psutil/tests</code>.</li>
</ul>
<p><strong>Bug fixes</strong></p>
