_PyErr_ChainExceptions1 no longer avallable to extension modules in Python 3.13 alpha headers
Bug report
Bug description:
The API _PyErr_ChainExceptions1 has been removed from public headers as part of this change in Python 3.13 alpha. It is the only C API available to chain exceptions replacing _PyErr_ChainExceptions. That change was publicly documented in the 3.12 whatsnew.
In my extemsion module I use _PyErr_ChainExceptions for exception chaining for Python <= 3.11 from PEP 490 and _PyErr_ChainExceptions1for 3.12+.
Please provide an approved way for C extensions to continue to chain exceptions. The function is still present and I can duplicate the prototype for all to continue working, but that is not a desirable solution.
CPython versions tested on:
3.13
