Huge congratulations to Thomas, Matt and Sam for sheparding through PEP 779 that moves the no-gil/free threaded python mode from experimental to supported:
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
Having confidence in the long term of this feature is great for anyone building on it. I’m very grateful to (and feel lucky to be working with!) the many folks who have been squashing bugs and improving performance, and to the people adding support for FT Python across the ecosystem!
The steering commitee have laid out some solid documentation and performance expectations for the ongoing work, and are setting an expectation for broad compatibility for future cpython work:
New experimental projects within CPython must be compatible with, and should be based on the free-threading build. The SC encourages this direction to reduce engineering complexity caused by supporting both GIL and free-threaded builds
I also appreciate the call for building out more high-level concurrency primitives: I think there are a lot of exciting projects to come as we move more of this into production!
