"Python's C API is covered by the Backwards Compatibility Policy, :pep:`387`. "
"While the C API will change with every minor release (e.g. from 3.9 to "
"3.10), most changes will be source-compatible, typically by only adding new "
"API. Changing existing API or removing API is only done after a deprecation "
"period or to fix serious issues."

"n'affecte cependant pas la compatibilité du code source. Typiquement, des "

#: c-api/stable.rst:108

"One issue that ``Py_LIMITED_API`` does not guard against is calling a "
"function with arguments that are invalid in a lower Python version. For "
"example, consider a function that starts accepting ``NULL`` for an argument. "
"In Python 3.9, ``NULL`` now selects a default behavior, but in Python 3.8, "
"the argument will be used directly, causing a ``NULL`` dereference and "
"crash. A similar argument works for fields of structs."

"Also note that the Limited API is not necessarily stable: compiling with "
"``Py_LIMITED_API`` with Python 3.8 means that the extension will run with "

#~ "Unfortunately, the API compatibility does not extend to binary "

#~ "field, might not break the API, but can break the ABI.  As a consequence, "
#~ "extension modules need to be recompiled for every Python release "
#~ "(although an exception is possible on Unix when none of the affected "

#~ "Malheureusement, la compatibilité de l'API ne s'étend pas à une "

#~ "type d'un attribut peut ne pas casser l'API mais casser l'ABI.  Par "
#~ "conséquent, les modules d'extension doivent être recompilés à chaque "
#~ "nouvelle version de Python (ce n'est exceptionnellement pas nécessaire "
#~ "sur Unix, si aucune des interfaces modifiées n'est utilisée). De plus, "
