Hello all,
I'm glad to announce the release of psutil 5.9.6:
https://github.com/giampaolo/psutil
About
=====
psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX, both 32-bit and 64-bit architectures. Supported Python versions are 2.7 and 3.6+. PyPy is also known to work.

**Enhancements**
- #1703: `cpu_percent()`_ and `cpu_times_percent()`_ are now thread safe,
meaning they can be called from different threads and still return
meaningful and independent results. Before, if (say) 10 threads called
``cpu_percent(interval=None)`` at the same time, only 1 thread out of 10
would get the right result.
- #2266: if `Process`_ class is passed a very high PID, raise `NoSuchProcess`_
instead of OverflowError. (patch by Xuehai Pan)
- #2246: drop python 3.4 & 3.5 support. (patch by Matthieu Darbois)
- #2290: PID reuse is now pre-emptively checked for `Process.ppid()`_ and
`Process.parents()`_.
- #2312: use ``ruff`` Python linter instead of ``flake8 + isort``. It's an
order of magnitude faster + it adds a ton of new code quality checks.
**Bug fixes**
- #2195, [Linux]: no longer print exception at import time in case /proc/stat
can't be read due to permission error. Redirect it to ``PSUTIL_DEBUG``
instead.
- #2241, [NetBSD]: can't compile On NetBSD 10.99.3/amd64. (patch by Thomas
Klausner)
- #2245, [Windows]: fix var unbound error on possibly in `swap_memory()`_
(patch by student_2333)
- #2268: ``bytes2human()`` utility function was unable to properly represent
negative values.
- #2252, [Windows]: `disk_usage()`_ fails on Python 3.12+. (patch by
Matthieu Darbois)
- #2284, [Linux]: `Process.memory_full_info()`_ may incorrectly raise
`ZombieProcess`_ if it's determined via ``/proc/pid/smaps_rollup``. Instead
we now fallback on reading ``/proc/pid/smaps``.
- #2287, [OpenBSD], [NetBSD]: `Process.is_running()`_ erroneously return
``False`` for zombie processes, because creation time cannot be determined.
- #2288, [Linux]: correctly raise `ZombieProcess`_ on `Process.exe()`_,
`Process.cmdline()`_ and `Process.memory_maps()`_ instead of returning a
"null" value.
- #2290: differently from what stated in the doc, PID reuse is not
pre-emptively checked for `Process.nice()`_ (set), `Process.ionice()`_,
(set), `Process.cpu_affinity()`_ (set), `Process.rlimit()`_
(set), `Process.parent()`_.
- #2308, [OpenBSD]: `Process.threads()`_ always fail with AccessDenied (also as
root).
