This article explains the significance of the CPython Application Binary Interface (ABI), specifically focusing on the stable ABI (abi3) which allows C extensions to remain compatible across different Python minor versions. It provides guidance for Python developers on how to leverage abi3 to simplify distribution and reduce maintenance overhead for native code packages.
Background
The CPython ABI defines how C extensions interact with the Python interpreter. Historically, changes between minor Python versions often broke binary compatibility, forcing recompilation of extensions.
