**Update:** Following the [announced plan](https://discuss.python.org/t/c-api-my-plan-to-clarify-private-vs-public-functions-in-python-3-13/30131), I reverted [50 private APIs](https://github.com/python/cpython/issues/112026#issuecomment-1813191948) which were removed in Python 3.13 alpha1. These APIs will be available again in the incoming Python 3.13 alpha2 (scheduled next Tuesday).
