Given that 2.7 has now been end-of-life for two and a half years,
I don't think we need such a detailed explanation here anymore of
the differences between Python 2 and Python 3.

Add a closure keyword-only parameter to exec(). It can only be specified when exec-ing a code object that uses free variables. When specified, it must be a tuple, with exactly the number of cell variables referenced by the code object. closure has a default value of None, and it must be None if the code object doesn't refer to any free variables.
On slow buildbot workers, some test_ssl tests fail randomly because
of short timeout (30 seconds). Use support.LONG_TIMEOUT instead which
is longer and also adjusted (by regrtest --timeout option) on
buildbot workers known to be slow.
In C++, the _PyObject_EXTRA_INIT macro now uses nullptr, rather than
0, to initialize the _ob_next and _ob_prev members of the PyObject
structure.
Fix test_cppext failure when Python is built with
./configure --with-trace-refs.
- add member() and nonmember() functions
- add deprecation warning for internal classes in enums not
becoming members in 3.13

Prevent `max_tasks_per_child` use with a "fork" mp_context to avoid deadlocks.
Also defaults to "spawn" when no mp_context is supplied for safe convenience.
38f331d introduced a delayed initialization routine to set up
ctypes formattable (`_ctypes_init_fielddesc`), but inadvertently
removed setting the `initialization` flag to 1 to avoid initting
each time.
Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.
* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
present.
One more thing that can help prevent people from using `preexec_fn`.
Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related.
