It can inspect local shared objects, wheels, PyPI packages, and package release histories. ### Project history The README says abi3audit was created by Trail of Bits and is now maintained as part of the Python Packaging Authority. GitHub release metadata for early versions still references the trailofbits repository, while current PyPI metadata points to the PyPA source repository. ### Adoption history abi3audit emerged from security and packaging concerns around Python's stable ABI. Its transfer to PyPA made it part of the Python packaging tool ecosystem, and the Homebrew input facts show it packaged as a command-line tool for macOS users. ### How it is used Users run abi3audit against a shared object, a wheel file, or a PyPI package name. The README documents verbose output for mismatch details and a JSON report mode for tooling integration. ### Why package nerds care abi3audit is package-nerd significant because abi3 wheels promise compatibility across CPython minor versions, but that promise is not automatically enforced at install time. The tool gives maintainers and distribution builders a way to check whether wheel tags and actual exported symbols agree. ### Timeline - 2022-09-20: Current GitHub repository created. - 2022-09-28: Earliest GitHub release in the current release list is v0.0.2. - 2022: Early release notes reference the Trail of Bits repository. - 2022-11: README links Trail of Bits writing about finding bugs with abi3audit. - 2025: Release series continues under PyPA with packaging and Python-version maintenance. - 2026-01-23: v0.0.26 released. ### Related projects - Related projects and standards include CPython's stable ABI, abi3 wheel tags, PyPI, PyPA packaging tools, setuptools' py-limited-api option, auditwheel, and Kaitai Struct parsers used by the project. ### Sources - Official README, PyPI metadata, GitHub repository metadata, and GitHub release metadata. ## Security Notes No matching local secret-handling manifest was found for abi3audit.
