There is also a C API change: PyFrame_New() is reverting to its
pre-2.1 signature.  The change introduced by nested scopes was a

eval_code2() setup code must INCREF cells it copies out of the

PythonInterpreterClassic and PythonInterpreterCarbon now have filetype "Atmp". The ConfigurePythonXXX scripts will set this to APPL when copying either of those to PythonInterpreter.

macostools.copy() now has an optional forcetype flag, which sets the filetype. This is used by various tools to set the type to APPL when copying interpreter template files (Atmp filetype).
