"Starting with the 3.13 release, CPython has experimental 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."

"The free-threaded build of CPython aims to provide similar thread-safety "

"to protect against concurrent modifications in ways that behave similarly to "
