Add _PyTypes_FiniTypes() best-effort function to clear static types:
don't deallocate a type if it still has subclasses.
remove_subclass() now sets tp_subclasses to NULL when removing the
last subclass.
"python -X showrefcount" now shows the total reference count after
clearing and destroyed the main Python interpreter. Previously, it
was shown before.
Py_FinalizeEx() now calls _PyDebug_PrintTotalRefs() after
finalize_interp_delete().
Ensure that directory file descriptors refer to directories different
from the current directory, and that src_dir_fd and dst_dir_fd refer
to different directories.
Add context manager open_dir_fd() in test.support.os_helper.
The signal module now creates its struct_siginfo type as a heap type
using PyStructSequence_NewType(), rather than using a static type.
Add 'siginfo_type' member to the global signal_state_t structure.
The _curses module now creates its ncurses_version type as a heap
type using PyStructSequence_NewType(), rather than using a static
type.
* Move _PyStructSequence_FiniType() definition to pycore_structseq.h.
* test.pythoninfo: log curses.ncurses_version.
The time module now creates its struct_time type as a heap
type using PyStructSequence_NewType(), rather than using a static
type.
* Add a module state to the time module: add traverse, clear and free
functions.
* Use PyModule_AddType().
* Remove the 'initialized' variable.
* _testembed_Py_Initialize() now uses the PyConfig API, rather than
deprecated Py_SetProgramName().
* Reduce INIT_LOOPS from 16 to 4: test_embed now takes 8.7 seconds
rather than 14.7 seconds.
Add _PyStructSequence_FiniType() and _PyStaticType_Dealloc()
functions to finalize a structseq static type in Py_Finalize().
Currrently, these functions do nothing if Python is built in release
mode.
Clear static types:
* AsyncGenHooksType: sys.set_asyncgen_hooks()
* FlagsType: sys.flags
* FloatInfoType: sys.float_info
* Hash_InfoType: sys.hash_info
* Int_InfoType: sys.int_info
* ThreadInfoType: sys.thread_info
* UnraisableHookArgsType: sys.unraisablehook
* VersionInfoType: sys.version
* WindowsVersionType: sys.getwindowsversion()
Fix an uncaught exception during help text generation when
argparse.BooleanOptionalAction is used with default=argparse.SUPPRESS
and help is specified.
* Add RETURN_GENERATOR and JUMP_NO_INTERRUPT opcodes.
* Trim frame and generator by word each.
* Minor refactor of frame.c
* Update test.test_sys to account for smaller frames.
* Treat generator functions as normal functions when evaluating and specializing.
The docstrings for MappingProxyType's keys(), values(), and items()
methods were never updated to reflect the changes that Python 3 brought
to these APIs, namely returning views rather than lists.
A small change to the documentation of datetime module , in the format codes section of stftime and strptime. Changed the description of format code '%W' from 'as a decimal number' to 'a zero padded decimal number' so it's in line with the example having leading zeros. Similar to the format code '%U' above.

The documentation on ``GenericAlias`` objects implies at multiple points that
only container classes can define ``__class_getitem__``. This is misleading.
This PR proposes a rewrite of the documentation to clarify that non-container
classes can define ``__class_getitem__``, and to clarify what it means when a
non-container class is parameterized.
See also: initial discussion of issues with this piece of documentation in
GH-29308, and previous BPO issue [42280](https://bugs.python.org/issue42280).
Also improved references in glossary and typing docs. Fixed some links.

This addresses [bpo-45554]() by expanding the `exitcode` documentation to also describe what `exitcode` will be in cases of normal termination, `sys.exit()` called, and on uncaught exceptions.

Use common error message for non-string attribute name in the builtin
functions getattr and hasattr.
The special check no longer needed since Python 3.0.
