What Every Python Developer Should Know About the CPython ABI

I explore the critical differences between the standard CPython ABI and the stable ABI3, explaining why understanding these distinctions is vital for building efficient, cross-version compatible Python extensions. By mastering these concepts, developers can avoid common pitfalls and ensure their code runs smoothly across different Python versions without unnecessary recompilation.

"Ignoring the stable ABI3 is like building a house on shifting sand; your extension might work today, but it will crumble with the next Python update."
