Now the special comparison methods like `__eq__` and `__lt__` return
NotImplemented if one of comparands is date and other is datetime
instead of ignoring the time part and the time zone or forcefully
return "not equal" or raise TypeError.
It makes comparison of date and datetime subclasses more symmetric
and allows to change the default behavior by overriding
the special comparison methods in subclasses.
It is now the same as if date and datetime was independent classes.
Setters for members with an unsigned integer type now support
the same range of valid values for objects that has a __index__()
method as for int.
Previously, Py_T_UINT, Py_T_ULONG and Py_T_ULLONG did not support
objects that has a __index__() method larger than LONG_MAX.
Py_T_ULLONG did not support negative ints. Now it supports them and
emits a RuntimeWarning.
By default, it preserves an inconsistent behavior of older Python
versions: packs the count into a 1-tuple if only one or none
options are specified (including 'update'), returns None instead of 0.
Except that setting wantobjects to 0 no longer affects the result.
Add a new parameter return_ints: specifying return_ints=True makes
Text.count() always returning the single count as an integer
instead of a 1-tuple or None.
Avoid race conditions in the creation of directories during concurrent
extraction in tarfile and zipfile.

`_multiprocessing` is only used under the `if _winapi:` block, this moves the import to be within the `_winapi` ImportError handling try/except for equivalent treatment.
When expanding and filtering paths for a `**` wildcard segment, build an `re.Pattern` object from the subsequent pattern parts, rather than the entire pattern, and match against the `os.DirEntry` object prior to instantiating a path object. Also skip compiling a pattern when expanding a `*` wildcard segment.
On macOS the statvfs interface returns block counts as
32-bit integers, and that results in bad reporting for
larger disks.
Therefore reimplement statvfs in terms of statfs, which
does use 64-bit integers for block counts.
Tested using a sparse filesystem image of 100TB.
Biased reference counting maintains two refcount fields in each object:
`ob_ref_local` and `ob_ref_shared`. The true refcount is the sum of these two
fields. In some cases, when refcounting operations are split across threads,
the ob_ref_shared field can be negative (although the total refcount must be
at least zero). In this case, the thread that decremented the refcount
requests that the owning thread give up ownership and merge the refcount
fields.
Fixes a few issues related to refleak tracking in the free-threaded build:
- Count blocks in abandoned segments
- Call `_mi_page_free_collect` earlier during heap traversal in order to get an accurate count of blocks in use.
- Add missing refcount tracking in `_Py_DecRefSharedDebug` and `_Py_ExplicitMergeRefcount`.
- Pause threads in `get_num_global_allocated_blocks` to ensure that traversing the mimalloc heaps is safe.
This changes a number of internal usages of `PyDict_SetDefault` to use `PyDict_SetDefaultRef`.
