### Describe the enhancement requested Hey all! 👋 I've started looking into adding support for the 3.13 free-threaded build of CPython. This aims to be a tracking issue for all work necessary to support it. A very high-level list of steps is (more details to follow as I investigate more issues): - [ ] Set up CI for free-threading (This needs to be done for 3.13 as well as part of #43519). - [ ] Move away from APIs that use borrowed references (`PyList_GetItem`, `PyDict_GetItem` and friends) under the free-threaded build - [ ] Audit C extension modules for thread-safety issues - [ ] `pyarrow` is a good candidate to test Cython again, since it's got lots of Cython code. Ideally test Cython nightly and also cython/cython#6226. - [ ] Mark C/Cython extension modules as thread-safe with the `Py_mod_gil` slot (or `PyUnstable_Module_SetGIL` / `freethreading_compatible`) - [ ] Upload (nightly) wheels for the free-threaded build. Hope this all sounds good! Let me know in case there's something that doesn't seem right. ### Component(s) Python -- This is an automated message from the Apache Git Service.
