Accepting request 1291400 from devel:languages:python:Factory
- Update to 3.14.0~b4:
- Tools/Demos
- gh-135968: Stubs for strip are now provided as part of an
iOS install.
- gh-133600: Backport file reorganization for .
Tools/wasm/wasi This should make backporting future code .
changes easier. It also simplifies instructions around how.
to do WASI builds in the devguide .
- Tests
- gh-135966: The iOS testbed now handles the app_packages
folder as a site directory.
- gh-135494: Fix regrtest to support excluding tests from
--pgo tests. Patch by Victor Stinner.
- Security
- gh-136053: marshal: fix a possible crash when deserializing
slice objects.
- gh-135661: Fix parsing start and end tags in
html.parser.HTMLParser according to the HTML5 standard.
- Whitespaces no longer accepted between </ and the tag
name. E.g. </ script> does not end the script section.
- Vertical tabulation (\v) and non-ASCII whitespaces no
longer recognized as whitespaces. The only whitespaces
are \t\n\r\f and space.
- Null character (U+0000) no longer ends the tag name.
- Attributes and slashes after the tag name in end tags are
now ignored, instead of terminating after the first > in
quoted attribute value. E.g. </script/foo=">"/>.
- Multiple slashes and whitespaces between the last
attribute and closing > are now ignored in both start and
end tags. E.g. <a foo=bar/ //>.
- Multiple = between attribute name and value are no longer
collapsed. E.g. <a foo==bar> produces attribute “foo”
with value “=bar”.
- Whitespaces between the = separator and attribute name or
value are no longer ignored. E.g. <a foo =bar> produces
two attributes “foo” and “=bar”, both with value None; <a
foo= bar> produces two attributes: “foo” with value “”
and “bar” with value None.
- gh-102555: Fix comment parsing in html.parser.HTMLParser
according to the HTML5 standard. --!> now ends the comment.
-- > no longer ends the comment. Support abnormally ended
empty comments <--> and <--->.
- Library
- gh-136286: Fix pickling failures for protocols 0 and 1 for
many objects realted to subinterpreters.

references in typing.evaluate_forward_ref().
- gh-85702: If zoneinfo._common.load_tzdata is given a
package without a resource a zoneinfo.ZoneInfoNotFoundError
is raised rather than a PermissionError. Patch by Victor
Stinner.
- gh-136028: Fix parsing month names containing “İ”
(U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE) in
time.strptime(). This affects locales az_AZ, ber_DZ, ber_MA
and crh_UA.
- gh-135995: In the palmos encoding, make byte 0x9b decode to
› (U+203A - SINGLE RIGHT-POINTING ANGLE QUOTATION MARK).
- gh-53203: Fix time.strptime() for %c and %x formats on
locales byn_ER, wal_ET and lzh_TW, and for %X format on
locales ar_SA, bg_BG and lzh_TW.
- gh-91555: An earlier change, which was introduced in
3.14.0b2, has been reverted. It disabled logging for
a logger during handling of log messages for that
logger. Since the reversion, the behaviour should be as it
was before 3.14.0b2.
- gh-135878: Fixes a crash of types.SimpleNamespace on free
threading builds, when several threads were calling its
__repr__() method at the same time.
- gh-135836: Fix IndexError in

asyncio.loop.create_connection() that could occur when the
Happy Eyeballs algorithm resulted in an empty exceptions
list during connection attempts.

format(Decimal(1.25), '.016f').
- gh-130662: Accept leading zeros in precision and
width fields for Fraction formatting, for example
format(Fraction(1, 3), '.016f').

separators in the fractional part for Fraction’s
formatting. Patch by Sergey B Kirpichev.
- gh-87790: Support underscore and comma as thousands
separators in the fractional part for Decimal’s
formatting. Patch by Sergey B Kirpichev.
- gh-130664: Handle corner-case for Fraction’s formatting:
treat zero-padding (preceding the width field by a zero
('0') character) as an equivalent to a fill character of
'0' with an alignment type of '=', just as in case of
float’s.
- Documentation
- gh-136155: EPUB builds are fixed by excluding
non-XHTML-compatible tags.
- Core and Builtins
- gh-109700: Fix memory error handling in
PyDict_SetDefault().

determined, the 48-bit node ID is now generated with a
cryptographically-secure pseudo-random number generator
(CSPRNG) as per RFC 9562, §6.10.3. This affects uuid1() and

values of csv.Dialect attributes.
- gh-132969: Prevent the ProcessPoolExecutor executor thread,
which remains running when shutdown(wait=False), from
attempting to adjust the pool’s worker processes after the
object state has already been reset during shutdown. A
combination of conditions, including a worker process
having terminated abormally, resulted in an exception and

-m asyncio pstree commands now show complete execution
context. Patch by Pablo Galindo.
- gh-127319: Set the allow_reuse_port class variable to False
on the XMLRPC, logging, and HTTP servers. This matches the
behavior in prior Python releases, which is to not allow
port reuse.
- gh-135171: Reverts the behavior of async generator
expressions when created with object w/o __aiter__ method
to the pre-3.13 behavior of raising a TypeError.
- gh-130077: Properly raise custom syntax errors when
incorrect syntax containing names that are prefixes of soft
keywords is encountered. Patch by Pablo Galindo.
- gh-135171: Reverts the behavior of generator expressions
when created with a non-iterable to the pre-3.13 behavior
of raising a TypeError. It is no longer possible to
cause a crash in the debugger by altering the generator
expression’s local variables. This is achieved by moving
the GET_ITER instruction back to the creation of the
generator expression and adding an additional check to
FOR_ITER.
- gh-116738: Make methods in heapq thread-safe on the free
threaded build.
- gh-134876: Add support to PEP 768 remote debugging for
Linux kernels which don’t have CONFIG_CROSS_MEMORY_ATTACH

the same underlying keys object.
- gh-134679: Fix crash in the free threading build’s QSBR
code that could occur when changing an object’s __dict__
attribute.
- gh-127682: No longer call __iter__ twice in list
comprehensions. This brings the behavior of list
comprehensions in line with other forms of iteration
- gh-133912: Fix the C API function PyObject_GenericSetDict
to handle extension classes with inline values.
- C API
- gh-134989: Fix Py_RETURN_NONE, Py_RETURN_TRUE and
Py_RETURN_FALSE macros in the limited C API 3.11 and
older: don’t treat Py_None, Py_True and Py_False as
immortal. Patch by Victor Stinner.
- gh-134989: Implement PyObject_DelAttr() and
PyObject_DelAttrString() as macros in the limited C API
3.12 and older. Patch by Victor Stinner.
- gh-133968: Add PyUnicodeWriter_WriteASCII() function to
write an ASCII string into a PyUnicodeWriter. The function
is faster than PyUnicodeWriter_WriteUTF8(), but has an
undefined behavior if the input string contains non-ASCII
characters. Patch by Victor Stinner.
- Build
- gh-119132: Remove “experimental” tag from the CPython
free-threading build.
- gh-135497: Fix the detection of MAXLOGNAME in the
configure.ac script.

Windows debug builds. Patch by Chris Eibl.
- gh-134632: Fixed build-details.json generation to use
INCLUDEPY, in order to reference the pythonX.Y subdirectory
of the include directory, as required in PEP 739, instead
of the top-level include directory.

Accepting request 1276737 from devel:languages:python:Factory
- Update to 3.14.0~b1:
- Tools/Demos
- gh-130453: Allow passing multiple keyword arguments with
the same function name in pygettext.
- gh-130195: Add warning messages when pygettext
unimplemented -a/--extract-all option is called.
- Tests
- gh-133131: The iOS testbed will now select the most
recently released “SE-class” device for testing if a device
isn’t explicitly specified.
- gh-91048: Add ability to externally inspect all pending
asyncio tasks, even if no task is currently entered on the
event loop.
- gh-109981: The test helper that counts the list of open
file descriptors now uses the optimised /dev/fd approach on
all Apple platforms, not just macOS. This avoids crashes
caused by guarded file descriptors.
- gh-132678: Add --prioritize to -m test. This option allows
the user to specify which selected tests should execute
first, even if the order is otherwise randomized. This is
particularly useful for tests that run the longest.
- gh-131290: Tests in Lib/test can now be correctly executed
as standalone scripts.
- Security
- gh-115322: The underlying extension modules behind
readline:, subprocess, and ctypes now raise audit events
on previously uncovered code paths that could lead to file
system access related to C function calling and external
binary execution. The ctypes.call_function audit hook has
also been fixed to use an unsigned value for its function
pointer.
- Library
- gh-133490: Add color support to PDB in remote mode.
- gh-132493: Avoid eagerly evaluating annotations in
functions decorated with reprlib.recursive_repr().
- gh-130645: Add color to stdlib argparse CLIs. Patch by Hugo
van Kemenade.

with the FORWARDREF format if evaluating the annotations
throws an exception other than NameError or AttributeError.
- gh-133351: Fix remote PDB to correctly request tab
completions for Python expressions from the server when
completing a continuation line of a multi-line Python
block.
- gh-133367: Add the --feature-version, --optimize,
and --show-empty options to the ast command-line
interface. Patch by Semyon Moroz.
- gh-133363: The cmd.Cmd class has been fixed to reliably
call the completedefault method whenever the do_shell
method is not defined and tab completion is requested for a
line beginning with !.
- gh-113081: Highlight syntax on source code in pdb.
- gh-133349: Introduced auto-indent in pdb multi-line input.
- gh-133306: Use \z instead of \Z in fnmatch.translate() and
glob.translate().
- gh-133306: Support \z as a synonym for \Z in regular
expressions.
- gh-133300: Make argparse.ArgumentParser’s suggest_on_error
a keyword-only parameter. Patch by Hugo van Kemenade.
- gh-133290: Fix attribute caching issue when setting
ctypes._Pointer._type_ in the undocumented and deprecated
ctypes.SetPointerType() function and the undocumented
set_type() method.
- gh-133223: When PDB is attached to a remote process, do a
better job of intercepting Ctrl+C and forwarding it to the
remote process.
- gh-133153: Do not complete pdb commands in interact mode of
pdb.
- gh-133139: Add the curses.assume_default_colors() function,
a refinement of the curses.use_default_colors() function
which allows to change the color pair 0.
- gh-133089: Use original timeout value for
subprocess.TimeoutExpired when the func subprocess.run()
is called with a timeout instead of sometimes a confusing
partial remaining time out value used internally on the
final wait().
- gh-133036: codecs.open() is now deprecated. Use open()
instead. Contributed by Inada Naoki.
- gh-132987: Many builtin and extension functions which
accept an unsigned integer argument, now use __index__() if
available.
- gh-124703: Set return code to 1 when aborting process from
pdb.
- gh-133005: Support passing preset option to tarfile.open()
when using 'w|xz' mode.
- gh-115032: Support for custom logging handlers with the
strm argument is deprecated and scheduled for removal in
Python 3.16. Define handlers with the stream argument
instead. Patch by Mariusz Felisiak.
- gh-132991: Add socket.IP_FREEBIND constant on Linux 2.4 and
later.
- gh-132995: Bump the version of pip bundled in ensurepip to
version 25.1.1
- gh-132933: The zipapp module now applies the filter when
creating the list of files to add, rather than waiting
until the file is being added to the archive.
- gh-121249: Always support the float complex and double
complex C types in the struct module. Patch by Sergey B
Kirpichev.
- gh-132915: fcntl.fcntl() and fcntl.ioctl() can now detect
a buffer overflow and raise SystemError. The stack and
memory can be corrupted in such case, so treat this error
as fatal.

and terminated.
- gh-132893: Improved statistics.NormalDist.cdf() accuracy
for inputs smaller than the mean.

modules in pdb.
- gh-129965: Add MIME types for .7z, .apk, .deb, .glb, .gltf,
.gz, .m4v, .php, .rar, .rpm, .stl and .wmv. Patch by Hugo
van Kemenade.
- gh-132742: fcntl.fcntl() now supports arbitrary bytes-like
objects, not only bytes. fcntl.ioctl() now automatically
retries system calls failing with EINTR and releases the
GIL during a system call even for large bytes-like object.
- gh-132451: The CLI for the PDB debugger now accepts a -p
PID argument to allow attaching to a running process. The
process must be running the same version of Python as the
one running PDB.
- gh-125618: Add a format parameter to
annotationlib.ForwardRef.evaluate(). Evaluating annotations
in the FORWARDREF format now succeeds in more cases that
would previously have raised an exception.

await statements in pdb.
- gh-132493: typing.Protocol now uses
annotationlib.get_annotations() when checking whether
or not an instance implements the protocol with
isinstance(). This enables support for isinstance checks
against classes with deferred annotations.
- gh-132536: Do not disable PY_THROW event in bdb because it
can’t be disabled.
- gh-132527: Include the valid typecode ‘w’ in the error
message when an invalid typecode is passed to array.array.
- gh-132099: The Bluetooth socket with the BTPROTO_HCI
protocol on Linux now accepts an address in the format of
an integer device_id, not only a tuple (device_id,).
- gh-81793: Fix os.link() on platforms (like Linux)
where the system link() function does not follow
symlinks. On Linux, it now follows symlinks by default
or if follow_symlinks=True is specified. On Windows, it
now raises an error if follow_symlinks=True is passed. On
macOS, it now raises an error if follow_symlinks=False is
passed and the system linkat() function is not available at
runtime.
- gh-132493: Support creation of typing.Protocol classes with
annotations that cannot be resolved at class creation time.
- gh-132491: Rename annotationlib.value_to_string to
annotationlib.type_repr() and provide better handling for
function objects.
- gh-132426: Add
annotationlib.get_annotate_from_class_namespace() as a
helper for accessing annotations in metaclasses, and remove
annotationlib.get_annotate_function.
- gh-70145: Add support for channels in Bluetooth HCI
protocol (BTPROTO_HCI).
- gh-131913: Add a shortcut function
multiprocessing.Process.interrupt() alongside the
existing multiprocessing.Process.terminate() and
multiprocessing.Process.kill() for an improved control over
child process termination.
- gh-132439: Fix PyREPL on Windows: characters entered via
AltGr are swallowed. Patch by Chris Eibl.
- gh-132429: Fix support of Bluetooth sockets on NetBSD
and DragonFly BSD. Add support for cid and bdaddr_type
in the BTPROTO_L2CAP address on FreeBSD. Return cid in
getsockname() for BTPROTO_L2CAP if it is not zero.
- gh-132106: QueueListener.start now raises a RuntimeError if
the listener is already started.
- gh-132417: Fix a NULL pointer dereference when a C function
called using ctypes with restype py_object returns NULL.
- gh-132385: Fix instance error suggestions trigger potential
exceptions in object.__getattr__() in traceback.
- gh-125866: Add optional add_scheme argument to
urllib.request.pathname2url(); when set to true, a complete
URL is returned. Likewise add optional require_scheme
argument to url2pathname(); when set to true, a complete
URL is accepted.
- gh-132308: A traceback.TracebackException now correctly
renders the __context__ and __cause__ attributes from
falsey Exception, and the exceptions attribute from falsey
ExceptionGroup.
- gh-130645: Add colour to argparse help output. Patch by
Hugo van Kemenade.
- gh-127495: In PyREPL, append a new entry to the
PYTHON_HISTORY file after every statement. This should
preserve command-line history after interpreter is
terminated. Patch by Sergey B Kirpichev.
- gh-129463: Comparison of annotationlib.ForwardRef objects
no longer uses the internal __code__ and __ast_node__
attributes, which are used as caches.
- gh-132250: Fixed the SystemError in cProfile when locating
the actual C function of a method raises an exception.
- gh-132064: annotationlib.get_annotations() now uses
the __annotate__ attribute if it is present, even if
__annotations__ is not present. Additionally, the function
now raises a TypeError if it is passed an object that does
not have any annotatins.
- gh-130664: Support the '_' digit separator in formatting
of the integral part of Decimal’s. Patch by Sergey B
Kirpichev.
- gh-131952: Add color output to the json CLI. Patch by Tomas
Roun.
- gh-132063: Prevent exceptions that evaluate as
falsey (namely, when their __bool__ method returns
False or their __len__ method returns 0) from being
ignored by concurrent.futures.ProcessPoolExecutor and
concurrent.futures.ThreadPoolExecutor.
- gh-132106: logging.handlers.QueueListener now implements
the context manager protocol, allowing it to be used in a
with statement.
- gh-132054: The application/yaml mime type (RFC 9512) is now
supported by mimetypes. Patch by Sasha “Nelie” Chernykh and
Hugo van Kemenade.
- gh-119605: Respect follow_wrapped for __init__() and
__new__() methods when getting the class signature for a
class with inspect.signature(). Preserve class signature
after wrapping with warnings.deprecated(). Patch by Xuehai
Pan.

module, and improve the performance of shlex.quote() by up
to 12x. Patch by Adam Turner.
- gh-85302: Add support for BTPROTO_SCO in sockets on
FreeBSD.
- gh-131757: Make functools.lru_cache() call the cached
function unlocked to allow concurrency.

interface. Contributed by Harry Lees.
- gh-100926: Move ctypes.POINTER() types cache from
a global internal cache (_pointer_type_cache) to
the ctypes._CData.__pointer_type__ attribute of the
corresponding ctypes types. This will stop the cache from
growing without limits in some situations.
- gh-85702: If zoneinfo._common.load_tzdata is given a
package without a resource a ZoneInfoNotFoundError is
raised rather than a IsADirectoryError.
- gh-123471: Make concurrent iterations over itertools.repeat
safe under free-threading.
- gh-131127: Systems using LibreSSL now successfully build.
- gh-89157: Make the pure Python implementation of
datetime.date.fromisoformat(), only accept ASCII strings
for consistency with the C implementation.
- gh-130941: Fix configparser.ConfigParser parsing empty
interpolation with allow_no_value set to True.
- gh-110067: Make heapq max-heap functions
heapq.heapify_max(), heapq.heappush_max(),
heapq.heappop_max(), and heapq.heapreplace_max()
public. Previous underscored naming is kept for backwards
compatibility. Additionally, the missing function
heapq.heappushpop_max() has been added to both the C and
Python implementations.
- gh-129098: Fix REPL traceback reporting when using
compile() with an inexisting file. Patch by Bénédikt Tran.
- gh-130631: http.cookiejar.join_header_words() is now more
similar to the original Perl version. It now quotes the
same set of characters and always quote values that end
with "\n".

tkinter.OptionMenu and tkinter.ttk.OptionMenu.
- gh-77065: Add keyword-only optional argument echo_char for
getpass.getpass() for optional visual keyboard feedback
support. Patch by Semyon Moroz.
- gh-130317: Fix PyFloat_Pack2() and PyFloat_Unpack2()
for NaN’s with payload. This corrects round-trip for
struct.unpack() and struct.pack() in case of the IEEE
754 binary16 “half precision” type. Patch by Sergey B
Kirpichev.
- gh-130402: Joining running daemon threads during
interpreter shutdown now raises PythonFinalizationError.
- gh-130167: Improve speed of difflib.IS_LINE_JUNK(). Patch
by Semyon Moroz.
- gh-101410: Added more detailed messages for domain errors
in the math module.
- gh-128384: Make warnings.catch_warnings use a context
variable for holding the warning filtering state if
the sys.flags.context_aware_warnings flag is set to
true. This makes using the context manager thread-safe
in multi-threaded programs. The flag is true by default
in free-threaded builds and is otherwise false. The
value of the flag can be overridden by the the -X
context_aware_warnings command-line option or by the
PYTHON_CONTEXT_AWARE_WARNINGS environment variable.
- gh-129719: Fix missing socket.CAN_RAW_ERR_FILTER constant
in the socket module on Linux systems. It was missing since
Python 3.11.
- gh-129027: Raise DeprecationWarning for
sys._clear_type_cache(). This function was deprecated in
Python 3.13 but it didn’t raise a runtime warning.
- gh-128307: Add eager_start keyword argument to
asyncio.loop.create_task()
- gh-127604: Add support for printing the C stack trace on
systems that support it via faulthandler.dump_c_stack() or
via the c_stack argument in faulthandler.enable().
- gh-127385: Add the F_DUPFD_QUERY constant to the fcntl
module.
- gh-126838: Add resolve_host keyword-only parameter to
urllib.request.url2pathname(), and fix handling of file
URLs with authorities.
- gh-82129: Fix NameError when calling
typing.get_type_hints() on a dataclasses.dataclass()
created by dataclasses.make_dataclass() with un-annotated
fields.
- gh-122559: Remove __reduce__() and __reduce_ex__() methods
that always raise TypeError in the C implementation
of io.FileIO, io.BufferedReader, io.BufferedWriter
and io.BufferedRandom and replace them with default
__getstate__() methods that raise TypeError. This restores
fine details of behavior of Python 3.11 and older versions.
- gh-122179: hashlib.file_digest() now raises BlockingIOError
when no data is available during non-blocking I/O. Before,
it added spurious null bytes to the digest.
- gh-53032: Expose decimal.IEEEContext() to support creation
of contexts corresponding to the IEEE 754 (2008) decimal
interchange formats. Patch by Sergey B Kirpichev.
- gh-120220: Deprecate the tkinter.Variable
methods trace_variable(), trace_vdelete() and
trace_vinfo(). Methods trace_add(), trace_remove() and
trace_info() can be used instead.
- gh-113539: webbrowser: Names in the BROWSER environment
variable can now refer to already registered web browsers,
instead of always generating a new browser command.
This makes it possible to set BROWSER to the value of one
of the supported browsers on macOS.
- bpo-44172: Keep a reference to original curses windows in
subwindows so that the original window does not get deleted
before subwindows.
- gh-75223: Deprecate undotted extensions in
mimetypes.MimeTypes.add_type(). Patch by Hugo van Kemenade.

keyboard shortcuts for the new, non-basic REPL (F1, F2, and
F3).
- Core and Builtins
- gh-133336: -J is no longer reserved for use by
Jython. Patch by Adam Turner.
- gh-133261: Fix bug where the cycle GC could untrack
objects in the trashcan because they looked like they were
immortal. When objects are added to the trashcan, we take
care to ensure they keep a mortal reference count.
- gh-133346: Added experimental color theming support to the
_colorize module.
- gh-132917: For the free-threaded build, check the process
memory usage increase before triggering a full automatic
garbage collection. If the memory used has not increased
10% since the last collection then defer it.
- gh-91048: Add a new python -m asyncio ps PID command-line
interface to inspect asyncio tasks in a running Python
process. Displays a flat table of await relationships. A
variant showing a tree view is also available as python -m
asyncio pstree PID. Both are useful for debugging async
code. Patch by Pablo Galindo, Łukasz Langa, Yury Selivanov,
and Marta Gomez Macias.
- gh-133304: Workaround NaN’s “canonicalization” in
PyFloat_Pack4() and PyFloat_Unpack4() on RISC-V.
- gh-133197: Improve SyntaxError error messages for
incompatible string / bytes prefixes.
- gh-133231: Add new utilities of observing JIT compilation:
sys._jit.is_available(), sys._jit.is_enabled(), and
sys._jit.is_active().
- gh-133194: ast.parse() will no longer parse new PEP 758
syntax with older feature_version passed.
- gh-131798: Split CALL_LEN into several uops allowing the
JIT to remove them when optimizing. Patch by Diego Russo.
- gh-131798: Use sym_new_type instead of sym_new_not_null for
_BUILD_STRING, _BUILD_SET
- gh-132942: Fix two races in the type lookup cache. This
affected the free-threaded build and could cause crashes
(apparently quite difficult to trigger).
- gh-131798: Propagate the return type of
_BINARY_OP_SUBSCR_TUPLE_INT in JIT. Patch by Tomas Roun
- gh-132952: Speed up startup with the -S argument by
importing the private _io module instead of io. This fixes
a performance regression introduced earlier in Python 3.14
development and restores performance to the level of Python
3.13.
- gh-131798: Allow the JIT to remove int guards after
_CALL_LEN by setting the return type to int. Patch by Diego
Russo
- gh-131798: Split CALL_TUPLE_1 into several uops allowing
the JIT to remove some of them. Patch by Tomas Roun
- gh-131798: Split CALL_STR_1 into several uops allowing the
JIT to remove some of them. Patch by Tomas Roun

for dict and set. Patch by Victor Stinner.
- gh-131591: Reset any PEP 768 remote debugging pending call
in children after os.fork() calls.

reference to the item while calling repr(item). Patch by
Victor Stinner.
- gh-132661: Implement PEP 750 (Template Strings). Add
new syntax for t-strings and implement new
internal string.templatelib.Template and
string.templatelib.Interpolation types.
- gh-132479: Fix compiler crash in certain circumstances
where multiple module-level annotations include
comprehensions and other nested scopes.
- gh-132747: Fix a crash when calling __get__() of a method
with a None second argument.
- gh-132744: Certain calls now check for runaway recursion
and respect the system recursion limit.
- gh-132449: Syntax errors that look like misspellings of
Python keywords now provide a helpful fix suggestion for
the typo. Contributed by Pablo Galindo Salgado.
- gh-132737: Support profiling code that requires __main__,
such as pickle.
- gh-132639: Added PyLong_AsNativeBytes(),
PyLong_FromNativeBytes() and
PyLong_FromUnsignedNativeBytes() to the limited C API.
- gh-100239: Add specialisation for BINARY_OP/SUBSCR on list
and slice.
- gh-132508: Uses tagged integers on the evaluation stack
to represent the instruction offsets when reraising an
exception. This avoids the need to box the integer which
could fail in low memory conditions.
- gh-124476: Fix decoding from the locale encoding in the
C.UTF-8 locale.
- gh-131927: Compiler warnings originating from the same
module and line number are now only emitted once, matching
the behaviour of warnings emitted from user code. This can
also be configured with warnings filters.
- gh-132457: Make staticmethod() and classmethod() generic.
- gh-131798: Use sym_new_type instead of sym_new_not_null for
_BUILD_LIST, _BUILD_SET, _BUILD_MAP
- gh-131798: Split CALL_TYPE_1 into several uops allowing the
JIT to remove some of them.
- gh-132386: Fix crash when passing a dict subclass as the
globals parameter to exec().
- gh-127682: No longer call __iter__ twice when creating and
executing a generator expression. Creating a generator
expression from a non-interable will raise only when the
generator expression is executed. This brings the behavior
of generator expressions in line with other generators.
- gh-132261: The internal storage for annotations and
annotate functions on classes now uses different keys in
the class dictionary. This eliminates various edge cases
where access to the __annotate__ and __annotations__
attributes would behave unpredictably.
- gh-132284: Don’t wrap base PyCFunction slots on class
creation if not overridden.
- gh-130415: Improve the JIT’s ability to remove unused
constant and local variable loads, and fix an issue where
deallocating unused values could cause JIT code to crash or
behave incorrectly.
- gh-126703: Fix possible use after free in cases where a
method’s definition has the same lifetime as its self.
- gh-132286: Fix that type.__annotate__ was not deleted, when
type.__annotations__ was deleted.
- gh-131798: Allow the JIT to remove an extra _TO_BOOL_BOOL
instruction after _CONTAINS_OP_DICT by setting the return
type to bool.
- gh-124715: Prevents against stack overflows when calling
Py_DECREF(). Third-party extension objects no longer need
to use the “trashcan” mechanism, as protection is now built
into the Py_DECREF() macro.
- gh-131798: Allow the JIT compiler to remove some type
checks for operations on lists, tuples, dictionaries, and
sets.
- gh-128398: Improve error message when an object supporting
the synchronous (resp. asynchronous) context manager
protocol is entered using async with (resp. with) instead
of with (resp. async with). Patch by Bénédikt Tran.
- gh-131798: Allow the JIT to remove unicode guards after
_BINARY_OP_SUBSCR_STR_INT by setting the return type to
string.
- gh-131878: Handle uncaught exceptions in the main input
loop for the new REPL.
- gh-131878: Fix support of unicode characters with two or
more codepoints on Windows in the new REPL.
- gh-126835: Move constant folding to the peephole
optimizer. Rename AST optimization related files
(Python/ast_opt.c -> Python/ast_preprocess.c), structs
(_PyASTOptimizeState -> _PyASTPreprocessState) and
functions (_PyAST_Optimize -> _PyAST_Preprocess,
_PyCompile_AstOptimize -> _PyCompile_AstPreprocess).
- gh-114809: Add support for macOS multi-arch builds with the
JIT enabled
- gh-131507: PyREPL now supports syntax
highlighing. Contributed by Łukasz Langa.
- gh-130907: If the __annotations__ of a module object
are accessed while the module is executing, return the
annotations that have been defined so far, without caching
them.
- gh-130104: Three-argument pow() now try calling __rpow__()
if necessary. Previously it was only called in two-argument
pow() and the binary power operator.
- gh-130070: Fixed an assertion error for exec() passed a
string source and a non-None closure. Patch by Bartosz
Sławecki.
- gh-129958: Fix a bug that was allowing newlines
inconsitently in format specifiers for single-quoted
f-strings. Patch by Pablo Galindo.
- gh-129858: elif statements that follow an else block now
have a specific error message.
- gh-69605: Add module autocomplete to PyREPL.
- gh-128555: Add the sys.flags.thread_inherit_context flag.
- This flag is set to true by default on the
free-threaded build and false otherwise. If the flag
is true, starting a new thread using threading.Thread
will, by default, use a copy of the contextvars.Context
from the caller of threading.Thread.start() rather than
using an empty context.
- Add the -X thread_inherit_context command-line option
and PYTHON_THREAD_INHERIT_CONTEXT environment variable,
which set the thread_inherit_context flag.
- Add the context keyword parameter to Thread. It can be
used to explicitly pass a context value to be used by a
new thread.
- Make the _contextvars module built-in.
- gh-123539: Improve SyntaxError message for using import ...
as and from ... import ... as with not a name.
- gh-102567: -X importtime now accepts value 2, which
indicates that an importtime entry should also be printed
if an imported module has already been loaded. Patch by
Noah Kim and Adam Turner.
- gh-116436: Improve error message when TypeError occurs
during dict.update()
- gh-103997: String arguments passed to “-c” are now
automatically dedented as if by textwrap.dedent(). This
allows “python -c” invocations to be indented in shell
scripts without causing indentation errors. (Patch by Jon
Crall and Steven Sun)
- gh-89562: Remove hostflags member from PySSLContext struct.
- C API
- gh-133166: Fix regression where PyType_GetModuleByDef()
returns NULL without setting TypeError when a static type
is passed.
- gh-133164: Add
PyUnstable_Object_IsUniqueReferencedTemporary() function
for determining if an object exists as a unique temporary
variable on the interpreter’s stack. This is a replacement
for some cases where checking that Py_REFCNT() is one is
no longer sufficient to determine if it’s safe to modify a
Python object in-place with no visible side effects.
- gh-133140: Add PyUnstable_Object_IsUniquelyReferenced()
as a replacement for Py_REFNCT(op) == 1 on free threaded
builds of Python.
- gh-131747: On non-Windows platforms, deprecate using
ctypes.Structure._pack_ to use a Windows-compatible layout
on non-Windows platforms. The layout should be specified
explicitly by setting ctypes.Structure._layout_ to 'ms'.
- gh-128972: For non-free-threaded builds, the memory layout
of PyASCIIObject is reverted to match Python 3.13. (Note
that the structure is not part of stable ABI and so its
memory layout is guaranteed to remain stable.)
- gh-133079: The undocumented APIs Py_C_RECURSION_LIMIT and
PyThreadState.c_recursion_remaining, added in 3.13, are
removed without a deprecation period.
- gh-132987: The k and K formats in PyArg_Parse() now support
the __index__() special method, like all other integer
formats.
- gh-132909: Fix an overflow when handling the K format in
Py_BuildValue(). Patch by Bénédikt Tran.
- gh-132798: Deprecated and undocumented
functions PyUnicode_AsEncodedObject(),
PyUnicode_AsDecodedObject(), PyUnicode_AsEncodedUnicode()
and PyUnicode_AsDecodedUnicode() are scheduled for removal
in 3.15.
- gh-132470: Creating a ctypes.CField with a byte_size that
does not match the actual type size now raises a ValueError
instead of crashing the interpreter.
- gh-112068: Add support of nullable arguments in
PyArg_Parse() and similar functions. Adding ? after any
format unit makes None be accepted as a value.
- gh-50333: Non-tuple sequences are deprecated as argument
for the (items) format unit in PyArg_ParseTuple() and other
argument parsing functions if items contains format units
which store a borrowed buffer or a borrowed reference.
- Build
- gh-113464: Use the cpython-bin-deps “externals” repository
for Windows LLVM dependency management. Installing LLVM
manually is no longer necessary for Windows JIT builds.
- gh-133183: iOS compiler shims now include
IPHONEOS_DEPLOYMENT_TARGET in target triples, ensuring that
SDK version minimums are honored.
- gh-133167: Fix compilation process with
--enable-optimizations and --without-docstrings.
- gh-133171: Since free-threaded builds do not support the
experimental JIT compiler, prevent these configurations
from being combined.
- gh-132758: Fix building with tail call interpreter and
pystats.
- gh-132649: The PClayout script now allows passing
--include-tcltk on Windows ARM64.
- gh-132257: Change the default LTO flags on GCC to not
pass -flto-partition=none, and allow parallelization of
LTO. For newer GNU makes and GCC, this has a multiple
factor speedup for LTO build times, with no noticeable loss
in performance.
- gh-132026: Fix use of undefined identifiers in platform
triplet detection on MIPS Linux platforms.
- Disabled GIL and experimental JIT cannot be combined.
- Remove python-3.3.0b1-test-posix_fadvise.patch (not needed
since kernel 3.6-rc1)
- _contextvars is not a dynamic module any more
(gh#python/cpython#128384)
- rename _testexternalinspection to _remotedebugging
(gh#python/cpython!133284)

- Tools/Demos
- gh-130453: Allow passing multiple keyword arguments with
the same function name in pygettext.
- gh-130195: Add warning messages when pygettext
unimplemented -a/--extract-all option is called.
- Tests
- gh-133131: The iOS testbed will now select the most
recently released “SE-class” device for testing if a device
isn’t explicitly specified.
- gh-91048: Add ability to externally inspect all pending
asyncio tasks, even if no task is currently entered on the
event loop.
- gh-109981: The test helper that counts the list of open
file descriptors now uses the optimised /dev/fd approach on
all Apple platforms, not just macOS. This avoids crashes
caused by guarded file descriptors.
- gh-132678: Add --prioritize to -m test. This option allows
the user to specify which selected tests should execute
first, even if the order is otherwise randomized. This is
particularly useful for tests that run the longest.
- gh-131290: Tests in Lib/test can now be correctly executed
as standalone scripts.
- Security
- gh-115322: The underlying extension modules behind
readline:, subprocess, and ctypes now raise audit events
on previously uncovered code paths that could lead to file
system access related to C function calling and external
binary execution. The ctypes.call_function audit hook has
also been fixed to use an unsigned value for its function

Accepting request 1245486 from devel:languages:python:Factory
- Update to the fifth development version of 3.14.0:
- Tools/Demos
- gh-129248: The iOS test runner now strips the log prefix
from each line output by the test suite.
- gh-104400: Fix several bugs in extraction by switching to
an AST parser in pygettext.
- Tests
- gh-129386: Add test.support.reset_code, which can be used
to reset various bytecode-level optimizations and local
instrumentation for a function.
- gh-128474: Disable test_embed test cases that segfault on
BOLT instrument binaries. The tests are only disabled when
BOLT is enabled.
- gh-128003: Add an option --parallel-threads=N to the
regression test runner that runs individual tests in
multiple threads in parallel in order to find concurrency
bugs. Note that most of the test suite is not yet reviewed
for thread-safety or annotated with @thread_unsafe when
necessary.
- Security
- gh-105704: When using urllib.parse.urlsplit() and
urllib.parse.urlparse() host parsing would not reject
domain names containing square brackets ([ and ]). Square
brackets are only valid for IPv6 and IPvFuture hosts
according to RFC 3986 Section 3.2.2. (bsc#1236705,
CVE-2025-0938, gh#python/cpython#105704).
- gh-126108: Fix a possible NULL pointer dereference in
PySys_AddWarnOptionUnicode().
- gh-80222: Fix bug in the folding of quoted strings
when flattening an email message using a modern email
policy. Previously when a quoted string was folded so
that it spanned more than one line, the surrounding
quotes and internal escapes would be omitted. This could
theoretically be used to spoof header lines using a
carefully constructed quoted string if the resulting
rendered email was transmitted or re-parsed.
- gh-119511: Fix a potential denial of service in the imaplib
module. When connecting to a malicious server, it could
cause an arbitrary amount of memory to be allocated. On
many systems this is harmless as unused virtual memory is
only a mapping, but if this hit a virtual address size
limit it could lead to a MemoryError or other process
crash. On unusual systems or builds where all allocated
memory is touched and backed by actual ram or storage
it could’ve consumed resources doing so until similarly
crashing.
- Library
- gh-129939: Comparison pages with highlighted changes
generated by the difflib.HtmlDiff class now support dark
mode.
- gh-129928: Raise sqlite3.ProgrammingError if a user-defined
SQL function with invalid number of parameters is
created. Patch by Erlend Aasland.
- gh-129583: Update bundled pip to 25.0.1
- gh-129766: Fix crash in warnings, when calling
_release_lock() with no existing lock.
- gh-129005: _pyio.FileIO.readall() now allocates, resizes,
and fills a data buffer using the same algorithm
_io.FileIO.readall() uses.
- gh-129646: Update the locale alias mapping in the locale
module to match the latest X Org locale alias mapping and
support new locales in Glibc 2.41.
- gh-128317: Put CLI calendar highlighting in private class,
removing highlight_day from public calendar.TextCalendar
API. Patch by Hugo van Kemenade.
- gh-129603: Fix bugs where sqlite3.Row objects could
segfault if their inherited description was set to
None. Patch by Erlend Aasland.
- gh-129559: Add bytearray.resize() method so bytearray can
be efficiently resized in place.
- gh-129502: Unlikely errors in preparing arguments for
ctypes callback are now handled in the same way as errors
raised in the callback of in converting the result of
the callback – using sys.unraisablehook() instead of
sys.excepthook() and not setting sys.last_exc and other
variables.
- gh-129403: Corrected ValueError message for asyncio.Barrier
and threading.Barrier.
- gh-129409: Fix an integer overflow in the csv module when
writing a data field larger than 2GB.
- gh-126400: Add a socket timeout keyword argument to
logging.handlers.SysLogHandler.

asyncio.staggered.staggered_race().
- gh-129205: Add os.readinto() to read into a buffer object
from a file descriptor.
- gh-128772: Fix pydoc for methods with the __module__
attribute equal to None.
- gh-129061: Fix FORCE_COLOR and NO_COLOR when empty
strings. Patch by Hugo van Kemenade.
- gh-92897: Scheduled the deprecation of the check_home
argument of sysconfig.is_python_build() to Python 3.15.
- gh-129064: Deprecate sysconfig.expand_makefile_vars(),
in favor of using sysconfig.get_paths() with the vars
argument.
- gh-128550: Removed an incorrect optimization relating
to eager tasks in asyncio.TaskGroup that resulted in
cancellations being missed.
- gh-128991: Release the enter frame reference within bdb
callback
- gh-118761: Reduce import time of pstats and zipfile by up
to 20%, by removing unnecessary imports to typing. Patch by
Bénédikt Tran.
- gh-128978: Fix a NameError in
sysconfig.expand_makefile_vars(). Patch by Bénédikt Tran.
- gh-128961: Fix a crash when setting state on an exhausted
array.array iterator.
- gh-128894: Fix
traceback.TracebackException._format_syntax_error not to
fail on exceptions with custom metadata.
- gh-128916: Do not attempt to set SO_REUSEPORT on sockets of
address families other than AF_INET and AF_INET6, as it is
meaningless with these address families, and the call with
fail with Linux kernel 6.12.9 and newer.
- gh-118761: Improve import time of tomllib by removing
typing, string, and tomllib._types imports. Patch by Taneli
Hukkinen.
- gh-128679: tracemalloc: Fix race conditions when
tracemalloc.stop() is called by a thread, while other
threads are tracing memory allocations. Patch by Victor
Stinner.
- gh-128891: Add specialized opcodes to opcode.opname.
- gh-118761: Reduce import time of gettext by up to ten
times, by importing re on demand. In particular, re is
no longer implicitly exposed as gettext.re. Patch by Eli
Schwartz.
- gh-118761: Reduce the import time of optparse when no help
text is printed. Patch by Eli Schwartz.
- gh-128657: Fix possible extra reference when using objects
returned by hashlib.sha256() under free threading.
- gh-118761: Reduce the import time of csv by up to five
times, by importing re on demand. In particular, re is no
more implicitly exposed as csv.re. Patch by Bénédikt Tran.
- gh-128308: Support the name keyword argument
for eager tasks in asyncio.loop.create_task(),
asyncio.create_task() and asyncio.TaskGroup.create_task(),
by passing on all kwargs to the task factory set by
asyncio.loop.set_task_factory().
- gh-118761: Improve the performance of base64.b16decode()
by up to ten times by more efficiently checking the
byte-string for hexadecimal digits. Reduce the import
time of base64 by up to six times, by no longer importing
re. Patch by Bénédikt Tran, Chris Markiewicz, and Adam
Turner.
- gh-128156: When using macOS system libffi, support for
complex types in ctypes is now checked at runtime (macOS
10.15 or newer). The types must also be available at build
time.
- gh-128636: Fix PyREPL failure when os.environ is
overwritten with an invalid value.
- gh-128498: Default to stdout isatty for color detection
instead of stderr. Patch by Hugo van Kemenade.
- gh-128384: Add locking to warnings to avoid some
data races when free-threading is used. Change
_warnings_runtime_state.mutex to be a recursive mutex
and expose it to warnings, via the _acquire_lock() and
_release_lock() functions. The lock is held when filters
and _filters_version are updated.
- gh-128509: Add sys._is_immortal() for identifying immortal
objects at runtime.
- gh-128479: Fix asyncio.staggered.staggered_race() leaking
tasks and issuing an unhandled exception.
- gh-128427: uuid.NIL and uuid.MAX are now available to
represent the Nil and Max UUID formats as defined by RFC
9562.
- gh-91279: zipfile.ZipFile.writestr() now respect
SOURCE_DATE_EPOCH that distributions can set centrally
and have build tools consume this in order to produce
reproducible output.
- gh-112064: Fix incorrect handling of negative read sizes in
HTTPResponse.read. Patch by Yury Manushkin.
- gh-58956: Fixed a frame reference leak in bdb.

asyncio._SelectorTransport is closed before writes are
completed.
- gh-121604: Add missing Deprecation warnings for
importlib.machinery.DEBUG_BYTECODE_SUFFIXES,
importlib.machinery.OPTIMIZED_BYTECODE_SUFFIXES,
importlib.machinery.WindowsRegistryFinder,
importlib.abc.ResourceLoader,
importlib.abc.SourceLoader.path_mtime().
- gh-127873: When -E is set, only ignore PYTHON_COLORS
and not FORCE_COLOR/NO_COLOR/TERM when colourising
output. Patch by Hugo van Kemenade.
- gh-125413: Add pathlib.Path.info attribute, which stores
an object implementing the pathlib.types.PathInfo protocol
(also new). The object supports querying the file type and
internally caching stat() results. Path objects generated
by iterdir() are initialized with file type information
gleaned from scanning the parent directory.
- gh-127712: Fix handling of the secure argument of
logging.handlers.SMTPHandler.

- gh-126332: Fix _pyrepl crash when entering a double CTRL-Z
on an overflowing line.
- gh-125553: Fix round-trip invariance for backslash
continuations in tokenize.untokenize().
- gh-91048: Add asyncio.capture_call_graph() and
asyncio.print_call_graph() functions.
- gh-124703: Quitting pdb in inline mode will emit a
confirmation prompt and exit gracefully now, instead of
printing an exception traceback.
- gh-123987: Fixed issue in NamespaceReader where a non-path
item in a namespace path, such as a sentinel added by an
editable installer, would break resource loading.

the loaded shared libraries for the current process.
- gh-55454: Add IMAP4 IDLE support to the imaplib
module. Patch by Forest.
- gh-119257: Show tab completions menu below the current
line, which results in less janky behaviour, and fixes a
cursor movement bug. Patch by Daniel Hollas
- gh-101410: Support custom messages for domain errors in the
math module (math.sqrt(), math.log() and math.atanh() were
modified as examples). Patch by Charlie Zhao and Sergey B
Kirpichev.
- gh-81340: Use os.copy_file_range() in shutil.copy(),
shutil.copy2(), and shutil.copyfile() functions by
default. An underlying Linux system call gives filesystems
an opportunity to implement the use of copy-on-write (in
case of btrfs and XFS) or server-side copy (in the case of
NFS.) Patch by Illia Volochii.
- bpo-27307: Add attribute and item access support to
string.Formatter in auto-numbering mode, which allows
format strings like ‘{.name}’ and ‘{[1]}’.

- gh-128563: Fix an issue where the “lltrace” debug feature
could have been incorrectly enabled for some frames.
- gh-129393: On FreeBSD, sys.platform doesn’t contain the
major version anymore. It is always 'freebsd', instead of
'freebsd13' or 'freebsd14'.
- gh-129345: Fix null pointer dereference in syslog.openlog()
when an audit hook raises an exception.
- gh-129231: Improve memory layout of JIT traces. Patch by
Diego Russo
- gh-129149: Add fast path for medium-size integers in
PyLong_FromUnsignedLong(), PyLong_FromUnsignedLongLong()
and PyLong_FromSize_t().
- gh-129201: The free-threaded version of the cyclic garbage
collector has been optimized to conditionally use CPU
prefetch instructions during the collection. This can
reduce collection times by making it more likely that
data is in the CPU cache when it is needed. The prefetch
instructions are enabled if the number of long-lived
objects (objects surviving a full collection) exceeds a
threshold.
- gh-129093: Fix f-strings such as f'{expr=}' sometimes not
displaying the full expression when the expression contains
!=.
- gh-124363: Treat debug expressions in f-string as raw
strings. Patch by Pablo Galindo
- gh-128714: Fix the potential races in get/set dunder
methods __annotations__, __annotate__ and __type_params__
for function object, and add related tests.
- gh-128799: Add frame of except* to traceback when it wraps
a naked exception.
- gh-128842: Collect JIT memory stats using pystats. Patch by
Diego Russo.
- gh-100239: Specialize BINARY_OP for bitwise logical
operations on compact ints.
- gh-128910: Undocumented and unused private C-API functions
_PyTrash_begin and _PyTrash_end are removed.
- gh-128807: Add a marking phase to the free-threaded
GC. This is similar to what was done in gh-126491. Since
the free-threaded GC does not have generations and is
not incremental, the marking phase looks for all objects
reachable from known roots. The roots are objects known to
not be garbage, like the module dictionary for sys. For
most programs, this marking phase should make the GC a bit
faster since typically less work is done per object.
- gh-100239: Add opcode BINARY_OP_EXTEND which executes a
pair of functions (guard and specialization functions)
accessed from the inline cache.
- gh-128563: A new type of interpreter has been added
to CPython. This interpreter uses tail calls for its
instruction handlers. Preliminary benchmark results suggest
7-11% geometric mean faster on pyperformance (depending
on platform), and up to 30% faster on Python-intensive
workloads. This interpreter currently only works on newer
compilers, such as clang-19. Other compilers will continue
using the old interpreter. Patch by Ken Jin, with ideas on
how to implement this in CPython by Mark Shannon, Garret
Gu, Haoran Xu, and Josh Haberman.
- gh-126703: Improve performance of iterating over lists and
tuples by using a freelist for the iterator objects.
- gh-127953: The time to handle a LINE event in
sys.monitoring (and sys.settrace) is now independent of the
number of lines in the code object.
- gh-128330: Restore terminal control characters on REPL
exit.
- gh-128016: Improved the SyntaxWarning message for invalid
escape sequences to clarify that such sequences will raise
a SyntaxError in future Python releases. The new message
also suggests a potential fix, i.e., Did you mean "\\e"?.
- gh-126004: Fix handling of UnicodeError.start and
UnicodeError.end values in the codecs.replace_errors()
error handler. Patch by Bénédikt Tran.
- gh-126004: Fix handling of UnicodeError.start
and UnicodeError.end values in the
codecs.backslashreplace_errors() error handler. Patch by
Bénédikt Tran.
- gh-126004: Fix handling of UnicodeError.start
and UnicodeError.end values in the
codecs.xmlcharrefreplace_errors() error handler. Patch by
Bénédikt Tran.
- gh-127119: Slightly optimize the int deallocator.
- gh-127349: Fixed the error when resizing terminal in Python
REPL. Patch by Semyon Moroz.
- gh-125723: Fix crash with gi_frame.f_locals when generator
frames outlive their generator. Patch by Mikhail Efimov.
- gh-126349: Add turtle.fill(), turtle.poly() and
turtle.no_animation() context managers. Patch by Marie
Roald and Yngve Mardal Moe.
- gh-115911: If the current working directory cannot be
determined due to permissions, then import will no longer
raise PermissionError. Patch by Alex Willmer.
- gh-112713: Added support for the Partitioned cookie flag in
http.cookies.
- C API
- gh-129533: Update PyGC_Enable(), PyGC_Disable(),
PyGC_IsEnabled() to use atomic operation for thread-safety
at free-threading build. Patch by Donghee Na.
- gh-89188: Implement PyUnicode_KIND() and PyUnicode_DATA()
as function, in addition to the macros with the same
names. The macros rely on C bit fields which have
compiler-specific layout. Patch by Victor Stinner.
- gh-91417: Remove PySequence_Fast() from the limited
C API, since this function has to be used with
PySequence_Fast_GET_ITEM which never worked in the limited
C API. Patch by Victor Stinner.
- gh-128509: Add PyUnstable_IsImmortal() for determining
whether an object is immortal.
- gh-129033: Remove _PyInterpreterState_GetConfigCopy() and
_PyInterpreterState_SetConfig() private functions. Use
instead PyConfig_Get() and PyConfig_Set(), public C API
added by PEP 741 “Python Configuration C API”. Patch by
Victor Stinner.
- gh-129033: Remove the private _Py_InitializeMain()
function. It was a provisional API added to Python 3.8 by
PEP 587. Patch by Victor Stinner.
- gh-128844: Add PyUnstable_TryIncRef() and
PyUnstable_EnableTryIncRef() unstable APIs. These
are helpers for dealing with unowned references in a
thread-safe way, particularly in the free threading build.
- gh-128911: Add PyImport_ImportModuleAttr() and
PyImport_ImportModuleAttrString() helper functions to
import a module and get an attribute of the module. Patch
by Victor Stinner.
- gh-128863: The following private functions are deprecated
and planned for removal in Python 3.18:
_PyBytes_Join(): use PyBytes_Join().
_PyDict_GetItemStringWithError(): use PyDict_GetItemStringRef().
_PyDict_Pop(): use PyDict_Pop().
_PyLong_Sign(): use PyLong_GetSign().
_PyLong_FromDigits() and _PyLong_New(): use PyLongWriter_Create().
_PyThreadState_UncheckedGet(): use PyThreadState_GetUnchecked().
_PyUnicode_AsString(): use PyUnicode_AsUTF8().
_Py_HashPointer(): use Py_HashPointer().
_Py_fopen_obj(): use Py_fopen().
The pythoncapi-compat project can be used to get these new
public functions on Python 3.13 and older. Patch by Victor Stinner.
- gh-126599: Remove some internal test APIs for the
experimental JIT compiler.
- gh-127925: Convert the decimal module to use PEP 757 C API
(export-import integers), offering some speed-up if the
integer part of the Decimal instance is small. Patch by
Sergey B Kirpichev.
- Build
- gh-129660: Drop test_embed from PGO training, whose
contribution in recent versions is considered to be
ignorable.
- gh-128902: Fix compile errors with Clang 9 and older due to
lack of __attribute__((fallthrough)) support.
- Remove upstreamed patches:
- CVE-2025-0938-sq-brackets-domain-names.patch
- 314a4-no-SO_REUSEPORT.patch

Patch by Victor Stinner. - gh-126742: Fix support of localized error messages reported by dlerror(3) and gdbm_strerror in ctypes and dbm.gnu functions respectively. Patch by Bénédikt Tran. - gh-122548: Adds two new local events to sys.monitoring, BRANCH_LEFT and BRANCH_RIGHT. This allows the two arms of the branch to be disabled independently, which should hugely improve performance of branch-level coverage tools. The old branch event, BRANCH is now deprecated. - gh-127847: Fix the position when doing interleaved seeks and reads in uncompressed, unencrypted zip files returned by zipfile.ZipFile.open(). - gh-127688: Add the SCHED_DEADLINE and SCHED_NORMAL constants to the os module. - gh-83662: Add missing __class_getitem__ method to the Python implementation of functools.partial(), to make it compatible with the C version. This is mainly relevant for alternative Python implementations like PyPy and GraalPy, because CPython will usually use the C-implementation of that function. - gh-127586: multiprocessing.pool.Pool now properly restores blocked signal handlers of the parent thread when creating processes via either spawn or forkserver. - gh-98188: Fix an issue in email.message.Message.get_payload() where data cannot be decoded if the Content Transfer Encoding mechanism contains trailing whitespaces or additional junk text.

Now it is always the opposite of \b. To get an old behavior, use (?!\A\Z)\B. To get a new behavior in old Python versions, use (?!\b). - gh-126639: tempfile.NamedTemporaryFile will now issue a ResourceWarning when it is finalized by the garbage collector without being explicitly closed. - gh-126624: Expose error code XML_ERROR_NOT_STARTED of Expat >=2.6.4 in xml.parsers.expat.errors. - gh-126225: getopt and optparse are no longer marked as deprecated. There are legitimate reasons to use one of these modules in preference to argparse, and none of these modules are at risk of being removed from the standard library. Of the three, argparse remains the recommended default choice, unless one of the concerns noted at the top of the optparse module documentation applies. - gh-124761: Add SO_REUSEPORT_LB constant to socket for FreeBSD. - gh-121720: enum.EnumDict can now be used without resorting to private API. - gh-123424: Add zipfile.ZipInfo._for_archive() setting default properties on ZipInfo objects. Patch by Bénédikt Tran and Jason R. Coombs. - gh-121676: Deprecate calling the Python implementation of functools.reduce() with a function or sequence as a keyword argument. This will be forbidden in Python 3.16 in order to match the C implementation. - gh-112015: ctypes.memoryview_at() now exists to create a memoryview object that refers to the supplied pointer and length. This works like ctypes.string_at() except it avoids a buffer copy, and is typically useful when implementing pure Python callback functions that are passed dynamically-sized buffers. - gh-95371: Added support for other image formats (PNG, PGM, and PPM) to the turtle module. Patch by Shin-myoung-serp. - Core and Builtins - gh-128078: Fix a SystemError when using anext() with a default tuple value. Patch by Bénédikt Tran. - gh-128717: Fix a crash when setting the recursion limit while other threads are active on the free threaded build. - gh-124483: Treat Py_DECREF and variants as escaping when generating opcode and uop metadata. This prevents the possibility of a __del__ method causing the JIT to behave incorrectly. - gh-126703: Improve performance of class methods by using a freelist. - gh-128137: Update PyASCIIObject layout to handle interned field with the atomic operation. Patch by Donghee Na. - gh-128192: Upgrade HTTP digest authentication algorithm for urllib.request by supporting SHA-256 digest authentication as specified in RFC 7616. - gh-126868: Increase usage of freelist for int allocation. - gh-114203: Optimize Py_BEGIN_CRITICAL_SECTION for simple recursive calls. - gh-127705: Adds stackref debugging when Py_STACKREF_DEBUG Inis set. Finds all double-closes and leaks, logging the Inorigin and last borrow. spired by HPy’s debug mode. Inhttps://docs.hpyproject.org/en/latest/debug-mode.html - gh-128079: Fix a bug where except* does not properly check the return value of an ExceptionGroup’s split() function, leading to a crash in some cases. Now when split() returns an invalid object, except* raises a TypeError with the original raised ExceptionGroup object chained to it. - gh-128030: Avoid error from calling PyModule_GetFilenameObject on a non-module object when importing a non-existent symbol from a non-module object. - gh-128035: Indicate through ssl.HAS_PHA whether the ssl module supports TLSv1.3 post-handshake client authentication (PHA). Patch by Will Childs-Klein. - gh-127274: Add a new flag, CO_METHOD, to co_flags that indicates whether the code object belongs to a function defined in class scope. - gh-66409: During the path initialization, we now check if base_exec_prefix is the same as base_prefix before falling back to searching the Python interpreter directory. - gh-127970: We now use the location of the libpython runtime library used in the current proccess to determine sys.base_prefix on all platforms implementing the dladdr function defined by the UNIX standard — this includes Linux, Android, macOS, iOS, FreeBSD, etc. This was already the case on Windows and macOS Framework builds. - gh-127773: Do not use the type attribute cache for types with incompatible MRO. - gh-127903: Objects/unicodeobject.c: fix a crash on DEBUG builds in _copy_characters when there is nothing to copy. - gh-127809: Fix an issue where the experimental JIT may infer an incorrect result type for exponentiation (** and **=), leading to bugs or crashes. - gh-126862: Fix a possible overflow when a class inherits from an absurd number of super-classes. Reported by Valery Fedorenko. Patch by Bénédikt Tran. - C API - gh-128400: Py_FatalError() no longer shows all threads on the free threaded build to prevent crashes. - gh-128629: Add macros Py_PACK_VERSION() and Py_PACK_FULL_VERSION() for bit-packing Python version numbers. - gh-128008: Add PyWeakref_IsDead() function, which tests if a weak reference is dead. - gh-127350: Add Py_fopen() function to open a file. Similar to the fopen() function, but the path parameter is a Python object and an exception is set on error. Add also Py_fclose() function to close a file, function needed for Windows support. Patch by Victor Stinner. - Build - gh-128627: For Emscripten builds the function pointer cast call trampoline now uses the wasm-gc ref.test instruction if it’s available instead of Wasm JS type reflection. - gh-128472: Skip BOLT optimization of functions using computed gotos, fixing errors on build with LLVM 19. - gh-115765: GNU Autoconf 2.72 is now required to generate !configure. Patch by Erlend Aasland. - gh-123925: Fix building the curses module on platforms with libncurses but without libncursesw. - gh-90905: Add support for cross-compiling to x86_64 on aarch64/arm64 macOS. - gh-128321: Set LIBS instead of LDFLAGS when checking if sqlite3 library functions are available. This fixes the ordering of linked libraries during checks, which was incorrect when using a statically linked libsqlite3. - gh-100384: Error on unguarded-availability in macOS builds, preventing invalid use of symbols that are not available in older versions of the OS. - gh-128104: Remove Py_STRFTIME_C99_SUPPORT conditions in favor of requiring C99 strftime(3) specifier support at build time. When cross-compiling, there is no build time check and support is assumed. - gh-127951: Add option --pystats to the Windows build to enable performance statistics collection.
