Hello, In Fedora, we’re rebuilding a set of around 4000 packages with Python 3.13.0 alpha 1. Here’s the current status. - ~2600 packages were rebuilt successfully so far. - ~1400 packages were not rebuilt yet, because their dependencies didn’t build. - current biggest blocker: [numpy](https://github.com/numpy/numpy/issues/25035) (blocks ~500 packages) - previous biggest blocker: [Cython](https://github.com/cython/cython/pull/5767) (fixed in Cython and [CPython](https://github.com/python/cpython/pull/111162) – we’ve backported both changes) - ~220 failed to build. This includes test failures, for packages where we run the test suite. - Some failures were already fixed; 158 still fail to build Here is a rough breakdown of the failures we encountered. ## Removal of C APIs with names prefixed by `_Py` or `_PY` 5 fail with: implicit declaration of function ‘\_Py\_IDENTIFIER‘: `python-zodbpickle`, `python-drgn`, `btrfs-progs`, `python3-typed_ast`, `python-multidict` 5 fail with: ‘\_PyThreadState\_UncheckedGet’ was not declared in this scope: `python-wsaccel`, `pybind11`, `pythia8`, `HepMC3`, `python-cffi` 4 fail with: implicit declaration of function ‘\_PyUnicode\_AsString: `python-gstreamer1`, `kernel-tools`, `python-cffi`, `python-cvxopt` 3 fail with: ‘\_PyLong\_Copy’ was not declared in this scope;
