* Moves the bytecode to the end of the corresponding PyCodeObject, and quickens it in-place.
* Removes the almost-always-unused co_varnames, co_freevars, and co_cellvars member caches
* _PyOpcode_Deopt is a new mapping from all opcodes to their un-quickened forms.
* _PyOpcode_InlineCacheEntries is renamed to _PyOpcode_Caches
* _Py_IncrementCountAndMaybeQuicken is renamed to _PyCode_Warmup
* _Py_Quicken is renamed to _PyCode_Quicken
* _co_quickened is renamed to _co_code_adaptive (and is now a read-only memoryview).
* Do not emit unused nonzero opargs anymore in the compiler.
Remove the private undocumented function
_PyEval_GetCoroutineOriginTrackingDepth() from the C API. Call the
public sys.get_coroutine_origin_tracking_depth() function instead.
Change the internal function
_PyEval_SetCoroutineOriginTrackingDepth():
* Remove the 'tstate' parameter;
* Add return value and raises an exception if depth is negative;
* No longer export the function: call the public
sys.set_coroutine_origin_tracking_depth() function instead.
Uniformize also function declarations in pycore_ceval.h.
Remove the following private undocumented functions from the C API:
* _PyEval_GetAsyncGenFirstiter()
* _PyEval_GetAsyncGenFinalizer()
* _PyEval_SetAsyncGenFirstiter()
* _PyEval_SetAsyncGenFinalizer()
Call the public sys.get_asyncgen_hooks() and sys.set_asyncgen_hooks()
functions instead.
Add new functions to pack and unpack C double (serialize and
deserialize):
* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()
Document these functions and add unit tests.
Rename private functions and move them from the internal C API
to the public C API:
* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()
Replace the "unsigned char*" type with "char*" which is more common
and easy to use.
Add methods __typing_subst__() in TypeVar and ParamSpec.
Simplify code by using more object-oriented approach, especially
the C code for types.GenericAlias and the Python code for
collections.abc.Callable.
Rename also struct _cframe to struct _PyCFrame.
Add a comment suggesting using public functions rather than using
directly the private _PyCFrame structure.
Rename private functions (no exported), add an underscore prefix:
* PyLineTable_InitAddressRange() => _PyLineTable_InitAddressRange()
* PyLineTable_NextAddressRange() => _PyLineTable_NextAddressRange()
* PyLineTable_PreviousAddressRange() => _PyLineTable_PreviousAddressRange()
Move private functions to the internal C API:
* _PyCode_Addr2EndLine()
* _PyCode_Addr2EndOffset()
* _PyCode_Addr2Offset()
* _PyCode_InitAddressRange()
* _PyCode_InitEndAddressRange(
* _PyLineTable_InitAddressRange()
* _PyLineTable_NextAddressRange()
* _PyLineTable_PreviousAddressRange()
No longer export the following internal functions:
* _PyCode_GetVarnames()
* _PyCode_GetCellvars()
* _PyCode_GetFreevars()
* _Py_GetSpecializationStats()
Add "extern" to pycore_code.h functions to identify them more easiliy
(they are still not exported).
<stdbool.h> is the standard/modern way to define embedd/extends Python free to define bool, true and false, but there are existing applications that use slightly different redefinitions, which fail if the header is included.
It's OK to use stdbool outside the public headers, though.

Move forward declarations of Python C API types to a new pytypedefs.h
header file to solve interdependency issues between header files.
pytypedefs.h contains forward declarations of the following types:
* PyCodeObject
* PyFrameObject
* PyGetSetDef
* PyInterpreterState
* PyLongObject
* PyMemberDef
* PyMethodDef
* PyModuleDef
* PyObject
* PyThreadState
* PyTypeObject
Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal
C API).
* Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h.
* Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR
macro which is always defined. gcc -Wundef emits a warning when
using _PY_SHORT_FLOAT_REPR but the macro is not defined, if
pycore_pymath.h include was forgotten.
Rename Include/buffer.h header file to Include/pybuffer.h to avoid
conflicts with projects having an existing "buffer.h" header file.
* Incude pybuffer.h before object.h in Python.h.
* Remove #include "buffer.h" from Include/cpython/object.h.
* Add a forward declaration of the PyObject type in pybuffer.h to fix
an inter-dependency issue.
