- Issue #13521: dict.setdefault() now does only one lookup for the given key,
making it "atomic" for many purposes. Patch by Filip GruszczyĆski.
+- Issue #10538: When using the "s*" code with PyArg_ParseTuple() to fill a
+ Py_buffer structure with data from an object supporting only the old
+ PyBuffer interface, a reference to the source objects is now properly added
+ to the Py_buffer.obj member.
