used as replacements, including ob_gc_bits, ob_tid, and mimalloc
internal data structures.
- gh-114456: Lower the recursion limit under a debug build of
WASI.
- gh-114083: Compiler applies folding of LOAD_CONST with following
instruction in a separate pass before other optimisations. This
enables jump threading in certain circumstances.
- gh-114388: Fix a RuntimeWarning emitted when assign an
integer-like value that is not an instance of int to an
attribute that corresponds to a C struct member of type T_UINT
and T_ULONG. Fix a double RuntimeWarning emitted when assign a
negative integer value to an attribute that corresponds to a C
struct member of type T_UINT.
- gh-114265: Compiler propagates line numbers before optimization,
leading to more optimization opportunities and removing the need
for the guarantee_lineno_for_exits hack.
- gh-112529: The free-threaded build now has its own thread-safe
GC implementation that uses mimalloc to find GC tracked objects.
It is non-generational, unlike the existing GC implementation.

disabled.
- gh-114058: Implement the foundations of the Tier 2 redundancy
eliminator.

that share state with the main interpreter, this points to the
same static memory structure. For interpreters with their own
obmalloc state, it is heap allocated. Add free_obmalloc_arenas()
which will free the obmalloc arenas and radix tree structures
for interpreters with their own obmalloc state.

capital NAN / INF) * incorrect output when applying the # format
option (alternate form)
- gh-102840: Fix confused traceback when floordiv, mod, or divmod
operations happens between instances of fractions.Fraction and
complex.
- gh-115165: Most exceptions are now ignored when attempting to
set the __orig_class__ attribute on objects returned when
calling typing generic aliases (including generic aliases
created using typing.Annotated). Previously only AttributeError
was ignored. Patch by Dave Shawley.
- gh-112903: Fix “issubclass() arg 1 must be a class” errors in
certain cases of multiple inheritance with generic aliases
(regression in early 3.13 alpha releases).
- gh-115133: Fix tests for XMLPullParser with Expat 2.6.0.
- gh-115059: io.BufferedRandom.read1() now flushes the underlying
write buffer.

non-existing paths in recursive glob().
- gh-67837: Avoid race conditions in the creation of directories
during concurrent extraction in tarfile and zipfile.
- gh-115060: Speed up pathlib.Path.glob() by removing redundant
regex matching.
- gh-97928: Partially revert the behavior of tkinter.Text.count().
By default it preserves the behavior of older Python versions,
except that setting wantobjects to 0 no longer has effect. 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.
- gh-114628: When csv.Error is raised when handling TypeError, do
not print the TypeError traceback.
- gh-85984: Added _POSIX_VDISABLE from C’s <unistd.h> to termios.

value.
- gh-109475: Fix support of explicit option value “–” in argparse
(e.g. --option=--).
- gh-49766: Fix date-datetime comparison. 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.
- gh-110190: Fix ctypes structs with array on Windows ARM64
platform by setting MAX_STRUCT_SIZE to 32 in stgdict. Patch by
Diego Russo
- gh-114678: Ensure that deprecation warning for ‘N’ specifier in
Decimal format is not raised for cases where ‘N’ appears in
other places in the format specifier. Based on patch by Stefan
Krah.
- gh-70303: Return both files and directories from

email.utils.
- gh-113280: Fix a leak of open socket in rare cases when error
occurred in ssl.SSLSocket creation.
- gh-77749: email.policy.EmailPolicy.fold() now always encodes
non-ASCII characters in headers if utf8 is false.
- gh-83383: Synchronization of the dbm.dumb database is now no-op
if there was no modification since opening or last
synchronization. The directory file for a newly created empty
dbm.dumb database is now created immediately after opening
instead of deferring this until synchronizing or closing.
- gh-91602: Add filter keyword-only parameter to
sqlite3.Connection.iterdump() for filtering database objects to
dump. Patch by Mariusz Felisiak.
- gh-112451: Prohibit subclassing pure-Python datetime.timezone.
This is consistent with C-extension implementation. Patch by
Mariusz Felisiak.
- gh-69893: Add the close() method for the iterator returned by
xml.etree.ElementTree.iterparse().
- gh-109653: Reduce the import time of threading module by ~50%.
Patch by Daniel Hollas.
- gh-114492: Make the result of termios.tcgetattr() reproducible
on Alpine Linux. Previously it could leave a random garbage in
some fields.
- gh-114315: Make threading.Lock a real class, not a factory
function. Add __new__ to _thread.lock type.
- gh-100414: Add dbm.sqlite3 as a backend to dbm, and make it the
new default dbm backend. Patch by Raymond Hettinger and Erlend
E. Aasland.
- gh-113267: Revert changes in gh-106584 which made calls of
TestResult methods startTest() and stopTest() unbalanced.
- gh-75128: Ignore an OSError in
asyncio.BaseEventLoop.create_server() when IPv6 is available but
the interface cannot actually support it.
- gh-114423: _DummyThread entries in threading._active are now
automatically removed when the related thread dies.
- gh-114257: Dismiss the FileNotFound error in
ctypes.util.find_library() and just return None on Linux.
- gh-114321: Expose more platform specific constants in the fcntl
module on Linux, macOS, FreeBSD and NetBSD.
- gh-114328: The tty.setcbreak() and new tty.cfmakecbreak() no
longer clears the terminal input ICRLF flag. This fixes a
regression introduced in 3.12 that no longer matched how OSes
define cbreak mode in their stty(1) manual pages.
- gh-114281: Remove type hints from Lib/asyncio/staggered.py. The
annotations in the typeshed project should be used instead.
- gh-101438: Avoid reference cycle in ElementTree.iterparse. The
iterator returned by ElementTree.iterparse may hold on to a file
descriptor. The reference cycle prevented prompt clean-up of the
file descriptor if the returned iterator was not exhausted.
- gh-114198: The signature for the __replace__ method on
dataclasses now has the first argument named self, rather than
obj.
- gh-104522: OSError raised when run a subprocess now only has
filename attribute set to cwd if the error was caused by a
failed attempt to change the current directory.
- gh-114149: Enum: correctly handle tuple subclasses in custom
__new__.
- gh-83648: Support deprecation of options, positional arguments
and subcommands in argparse.
- gh-114087: Speed up dataclasses.asdict up to 1.35x.
- gh-109534: Fix a reference leak in
asyncio.selector_events.BaseSelectorEventLoop when SSL
handshakes fail. Patch contributed by Jamie Phan.
- gh-79634: Accept path-like objects as patterns in
pathlib.Path.glob() and rglob().
- gh-112202: Ensure that a asyncio.Condition.notify() call does
not get lost if the awakened Task is simultaneously cancelled or
encounters any other error.
- gh-113951: Fix the behavior of tag_unbind() methods of
tkinter.Text and tkinter.Canvas classes with three arguments.
Previously, widget.tag_unbind(tag, sequence, funcid) destroyed
the current binding for sequence, leaving sequence unbound, and
deleted the funcid command. Now it removes only funcid from the
binding for sequence, keeping other commands, and deletes the
funcid command. It leaves sequence unbound only if funcid was
the last bound command.
- gh-97959: Fix rendering class methods, bound methods, method and
function aliases in pydoc. Class methods no longer have “method
of builtins.type instance” note. Corresponding notes are now
added for class and unbound methods. Method and function aliases
now have references to the module or the class where the origin
was defined if it differs from the current. Bound methods are
now listed in the static methods section. Methods of builtin
classes are now supported as well as methods of Python classes.
- gh-113796: Add more validation checks in the csv.Dialect
constructor. ValueError is now raised if the same character is
used in different roles.
- gh-113732: Fix support of QUOTE_NOTNULL and QUOTE_STRINGS in
csv.reader().
- gh-113225: Speed up pathlib.Path.walk() by using
os.DirEntry.path where possible.
- gh-89039: When replace() method is called on a subclass of
datetime, date or time, properly call derived constructor.
Previously, only the base class’s constructor was called.
- Also, make sure to pass non-zero fold values when creating
subclasses in various methods. Previously, fold was silently
ignored.
- gh-112919: Speed-up datetime.datetime.replace(),
datetime.date.replace() and datetime.time.replace().
- gh-59013: Set breakpoint on the first executable line of the
function, instead of the line of function definition when the
user do break func using pdb
- gh-112343: Improve handling of pdb convenience variables to
avoid replacing string contents.
- gh-112240: Add option to calendar module CLI to specify the
weekday to start each week. Patch by Steven Ward.
- gh-111741: Recognise image/webp as a standard format in the
mimetypes module.
- gh-43457: Fix the tkinter widget method wm_attributes(). It now
accepts the attribute name without the minus prefix to get
window attributes and allows to specify attributes and values to
set as keyword arguments. Add new optional keyword argument
return_python_dict: calling
w.wm_attributes(return_python_dict=True) returns the attributes
as a dict instead of a tuple. Calling w.wm_attributes() now
returns a tuple instead of string if wantobjects was set to 0.
- gh-82626: Many functions now emit a warning if a boolean value
is passed as a file descriptor argument.
- gh-111051: Added check for file modification during debugging
with pdb
- gh-110345: Show the Tcl/Tk patchlevel (rather than version) in
tkinter._test().

directory exists and creating it, directly call os.makedirs()
with the kwarg exist_ok=True.

filters with properties of zero length. Patch by Radislav
Chugunov.
- gh-96471: Add queue.Queue termination with shutdown().
- gh-101599: Changed argparse flag options formatting to remove
redundancy.
- gh-85984: Add POSIX pseudo-terminal functions os.posix_openpt(),
os.grantpt(), os.unlockpt(), and os.ptsname().
- gh-102512: When os.fork() is called from a foreign thread (aka
_DummyThread), the type of the thread in a child process is
changed to _MainThread. Also changed its name and daemonic
status, it can be now joined.
- gh-88569: Add os.path.isreserved(), which identifies reserved
pathnames such as “NUL”, “AUX” and “CON”. This function is only
available on Windows.
- Deprecate pathlib.PurePath.is_reserved().

- gh-115015: Fix a bug in Argument Clinic that generated incorrect
code for methods with no parameters that use the METH_METHOD |
METH_FASTCALL | METH_KEYWORDS calling convention. Only the
positional parameter count was checked; any keyword argument
passed would be silently accepted.
- C API

and PyLong_FromUnsignedNativeBytes() functions.
- gh-114685: PyBuffer_FillInfo() now raises a SystemError if
called with PyBUF_READ or PyBUF_WRITE as flags. These flags
should only be used with the PyMemoryView_* C API.
- gh-114685: PyObject_GetBuffer() now raises a SystemError if
called with PyBUF_READ or PyBUF_WRITE as flags. These flags
should only be used with the PyMemoryView_* C API.
- gh-114626: Add PyCFunctionFast and PyCFunctionFastWithKeywords

into a dictionary if the key is not already present. This is
similar to dict.setdefault(), but returns an integer value
indicating if the key was already present. It is also similar to
PyDict_SetDefault(), but returns a strong reference instead of a
borrowed reference.

Python 3.13.0 alpha 2¶
- Core and Builtins:
- Don’t include comments in f-string debug expressions. Patch
by Pablo Galindo
- Slightly optimize the Tier 2 (uop) interpreter by only
loading oparg and operand when needed. Also double the
trace size limit again, to 512 this time.
- Change docstrings of __dict__ and __weakref__.
- Lower the max parser stack depth to 1000 under WASI debug
builds.
- When Python is built in debug mode, set the C recursion
limit to 500 instead of 1500. A debug build is likely built
with low optimization level which implies higher stack
memory usage than a release build. Patch by Victor Stinner.
- Enable translating unspecialized FOR_ITER to Tier 2.
- Make hashlib related modules thread-safe without the GIL
- Deprecate assignment to a function’s __code__ field when
the new code object is of a mismatched type (e.g., from a
generator to a plain function).
- Raise exception if frame.clear() is called on a suspended
frame.
- Implement native thread ids for GNU KFreeBSD.
- Use exponential backoff to reduce the number of failed tier
2 optimization attempts by over 99%.
- Joining a thread now ensures the underlying OS thread has
exited. This is required for safer fork() in multi-threaded
processes.
- Make sure that tier 2 traces are de-optimized if the code
is instrumented
