The Steering Council (SC) approves PEP 779 [Criteria for supported status for free-threaded Python], with the effect of removing the “experimental” tag from the free-threaded build of Python 3.14 [...]

With these recommendations and the acceptance of this PEP, we as the Python developer community should broadly advertise that free-threading is a supported Python build option now and into the future, and that it will not be removed without following a proper deprecation schedule. [...]

Keep in mind that any decision to transition to Phase III, with free-threading as the default or sole build of Python is still undecided, and dependent on many factors both within CPython itself and the community. We leave that decision for the future.
