- Update F00251-change-user-install-location.patch to install packages
in /usr/local by default when using pip outside of a RPMBUILD
environment.
- Update to 3.13.0~b4:
- Tests
- gh-121084: Fix test_typing random leaks. Clear typing ABC
caches when running tests for refleaks (-R option): call
_abc_caches_clear() on typing abstract classes and their
subclasses.
- gh-121160: Add a test for
readline.set_history_length(). Note that this test may fail
on readline libraries.
- gh-121200: Fix test_expanduser_pwd2() of
test_posixpath. Call getpwnam() to get pw_dir, since it
can be different than getpwall() pw_dir.
- gh-121188: When creating the JUnit XML file, regrtest
now escapes characters which are invalid in XML, such
as the chr(27) control character used in ANSI escape
sequences.

Python 3.13) is now keyword-only.

site.register_readline() helper. The CAN_USE_PYREPL
variable now will be initialized, when imported.
- gh-121332: Fix constructor of ast nodes with custom
_attributes. Previously, passing custom attributes would
raise a DeprecationWarning. Passing arguments to the
constructor that are not in _fields or _attributes remains
deprecated.

accessing the depracated atributes of the importlib.abc
module.

asyncio.

did not honor exit_on_error=False.

globals from files passed using the -i argument would not
be included in the REPL’s global namespace.
- gh-120782: Fix wrong references of the datetime types after
reloading the module.
- gh-120713: datetime.datetime.strftime() now 0-pads years
with less than four digits for the format specifiers %Y and
%G on Linux.
- gh-117983: Defer the threading import in importlib.util
until lazy loading is used.
- gh-119189: When using the ** operator or pow() with
Fraction as the base and an exponent that is not rational,
a float, or a complex, the fraction is no longer converted
to a float.
- gh-118714: Allow restart in post-mortem debugging of
pdb. Removed restart message when the user quits pdb from
post-mortem mode.

private.

correctly respect the history when an input hook was
set. Patch by Pablo Galindo

remain exhausted, once they become exhausted.
- gh-121439: Allow tuples of length 20 in the freelist to be
reused.
- gh-121368: Fix race condition in _PyType_Lookup in the
free-threaded build due to a missing memory fence. This
could lead to _PyType_Lookup returning incorrect results on
arm64.
- gh-121130: Fix f-strings with debug expressions in format
specifiers. Patch by Pablo Galindo
- gh-121115: PyLong_AsNativeBytes() no longer

it couldn’t be used in 3rd party code. Patch by Victor

Seprevents its argument from being garbage collected
Several functions that take char * are now documented
Seas possibly preventing string objects from being
Segarbage collected; refer to their documentation
Sefor details: PyUnicode_InternFromString(),
SePyDict_SetItemString(), PyObject_SetAttrString(),
SePyObject_DelAttrString(), PyUnicode_InternFromString(),
Seand PyModule_Add* convenience functions

interning strings, which were falsely triggered by stable
ABI extensions.
