+Starting with the 3.13 release, CPython has support for a build of
 Python called :term:`free threading` where the :term:`global interpreter lock`
 (GIL) is disabled.  Free-threaded execution allows for full utilization of the
 available processing power by running threads in parallel on available CPU cores.
 While not all software will benefit from this automatically, programs
 designed with threading in mind will run faster on multi-core hardware.
