-1. Fix NULL dereference bug in ga_vectorcall by using PyObject_Vectorcall() instead of calling PyVectorcall_Function().
-2. Remove the redundant Py_XDECREF call in _Py_make_parameters
+Fix vectorcall support in types.GenericAlias when the underlying type does not support the vectorcall protocol. Fix possible leaks in types.GenericAlias and types.UnionType in case of memory error.
