In principle, any CPython extension can be built against this\nAPI/ABI and will remain forward compatible with future minor versions of CPython.\nIn other words: if you build against the stable ABI for Python 3.5, your\nextension should work without modification on Python 3.9.\n\nThe stable ABI simplifies packaging of CPython extensions, since the packager\nonly needs to build one `abi3` wheel that targets the minimum supported Python\nversion.\n\nTo signal that a Python wheel contains `abi3`-compatible extensions,\nthe Python packaging ecosystem uses the `abi3` wheel tag, e.g.:\n\n```text\npyrage",
