While floor/ceil 's documentation are very precise, `truncate` was not explained. I actually had to search online to understand the difference between `truncate` and `floor` (admittedly, once I remembered that numbers are signed, and that floating numbers actually uses a bit for negation symbol instead of two complement, it became obvious)

The second parameter (named `func`) has been present since the `locale`
module was introduced in eef1d4e8b1, but has never been documented.
This commit updates the documentation for `locale.atof` to clarify the
behavior of the function and how the `func` parameter is used.

Move the private _PyFrameEvalFunction type, and private
_PyInterpreterState_GetEvalFrameFunc() and
_PyInterpreterState_SetEvalFrameFunc() functions to the internal C
API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.
Update the _PyFrameEvalFunction documentation.
Move the private undocumented _PyEval_EvalFrameDefault() function to
the internal C API. The function now uses the _PyInterpreterFrame
type which is part of the internal C API.
- Remove ``--with-tclk-*`` options from `configure`
- Use pkg-config to detect `_tkinter` dependencies (Tcl/Tk, X11)
- Manual override via environment variables `TCLTK_CFLAGS` and `TCLTK_LIBS`
Update documentation to note that in some circumstances,
KeyboardInterrupt may cause code to enter an inconsistent state. Also
document sample workaround to avoid KeyboardInterrupt, if needed.
In rare cases, capturing group could get wrong result.
Regular expression engines in Perl and Java have similar bugs.
The new behavior now matches the behavior of more modern
RE engines: in the regex module and in PHP, Ruby and Node.js.
The enter_context is updated with following information: 'The :meth:`__enter__` method
returns the ExitStack instance, and performs no additional operations.'

* `PyFrame_FastToLocalsWithError` and `PyFrame_LocalsToFast` are no longer called during profile and tracing.
(Contributed by Fabio Zadrozny)
* Make accesses to a frame's `f_locals` safe from C code, not relying on calls to `PyFrame_FastToLocals` or `PyFrame_LocalsToFast`.
* Document new `PyFrame_GetLocals` C-API function.
The goal here is to reduce potential confusion between
`assert_type(val, type)` and `assert isinstance(val, typ)`.
The former is meant to ask a type checker to confirm a fact, the latter
is meant to tell a type checker a fact. The behaviour of the latter more
closely resembles what I'd expect from the prior phrasing of
"assert [something] to the type checker".
After a long deliberation we ended up feeling that the message argument for Future.cancel(), added in 3.9, was a bad idea, so we're deprecating it in 3.11 and plan to remove it in 3.13.
People are testing those blocs with the default
inline_comment_prefixes of None, leading to a:
configparser.InterpolationSyntaxError: '$' must be followed by '$' or '{', found: '$ sign ($ is the only character that needs to be escaped)'
* Add the metadata_encoding parameter in the zipfile.ZipFile constructor.
* Add the --metadata-encoding option in the zipfile CLI.

Clarifies a versionchanged note on crc32 & adler32 docs that the workaround is only needed for Python 2 and earlier.
Also cleans up an unnecessary intermediate variable in the implementation.

Define *posix_venv* and *nt_venv* sysconfig installation schemes
to be used for bootstrapping new virtual environments.
Add *venv* sysconfig installation scheme to get the appropriate one of the above.
The schemes are identical to the pre-existing
*posix_prefix* and *nt* install schemes.
The venv module now uses the *venv* scheme to create new virtual environments
instead of hardcoding the paths depending only on the platform. Downstream
Python distributors customizing the *posix_prefix* or *nt* install
scheme in a way that is not compatible with the install scheme used in
virtual environments are encouraged not to customize the *venv* schemes.
When Python itself runs in a virtual environment,
sysconfig.get_default_scheme and
sysconfig.get_preferred_scheme with `key="prefix"` returns
*venv*.
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.
As per the comments, this mirrors the [datetime documentation](https://docs.python.org/3/library/datetime.html#datetime.datetime.fromtimestamp).
