7.2.2 — 2026-01-28 ^^^^^^^^^^^^^^^^^^

Enhancements

• :gh:2705: [Linux]: :meth:Process.wait now uses pidfd_open() + poll() (no busy loop). Requires Linux >= 5.3 and Python >= 3.9.
• :gh:2705: [macOS], [BSD]: :meth:Process.wait now uses kqueue() (no busy loop).

Bug fixes

• :gh:2701, [macOS]: fix compilation error on macOS < 10.7. (patch by Sergey Fedorov)
• :gh:2707, [macOS]: fix potential memory leaks in error paths of :meth:Process.memory_full_info and :meth:Process.threads.
• :gh:2708, [macOS]: :meth:Process.cmdline and :meth:Process.environ may fail with OSError: [Errno 0] Undefined error (from sysctl(KERN_PROCARGS2)). They now raise :exc:AccessDenied instead.

7.2.1 — 2025-12-29 ^^^^^^^^^^^^^^^^^^

Bug fixes

• :gh:2699, [FreeBSD], [NetBSD]: :func:heap_info does not detect small allocations (<= 1K). In order to fix that, we now flush internal jemalloc cache before fetching the metrics.

7.2.0 — 2025-12-23 ^^^^^^^^^^^^^^^^^^

Enhancements

• :gh:1275: new :func:heap_info and :func:heap_trim functions, providing direct access to the platform's native C heap allocator (glibc, mimalloc, libmalloc). Useful to create tools to detect memory leaks.
• :gh:2403, [Linux]: publish wheels for Linux musl.
• :gh:2680: unit tests are no longer installed / part of the distribution. They now live under tests/ instead of psutil/tests.

Bug fixes

• :gh:2684, [FreeBSD], [critical]: compilation fails on FreeBSD 14 due to missing include.
• :gh:2691, [Windows]: fix memory leak in :func:net_if_stats due to missing Py_CLEAR.
