Build and C API Changes
=======================

* The :c:func:`PyByteArray_Init` and :c:func:`PyByteArray_Fini` functions have
been removed. They did nothing since Python 2.7.4 and Python 3.2.0, were
excluded from the limited API (stable ABI), and were not documented.

* The result of :c:func:`PyExceptionClass_Name` is now of type
``const char *`` rather of ``char *``.
(Contributed by Serhiy Storchaka in :issue:`33818`.)
